THERAPEUTIC BLANKET
[0001]
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0002] The present invention relates to a therapeutic blanket, and, more
particularly, to
weighted therapeutic blankets.
2. Description of the Related Art
[0003] The tactile system provides input to the brain for interpretation of
various types of
touch, pressure, temperature and pain through receptors in the skin. For
example, deep pressure
touch can be very calming. This type of input facilitates the release of
dopamine, also known as
the "pleasure chemical", in the brain that helps people maintain emotional
neutrality. Dopamine
activates the parasympathetic nervous system for a relaxed, neutral and
balanced homeostatic
state. Dopamine may neutralize cortisol and adrenaline, which contribute to
the fight or flight
response of the autonomic nervous system. Conversely, an excess of dopamine
may increase
hyperactivity, which may then be regulated by increasing serotonin levels via
the proprioceptive
system. Proprioception refers to the information gathered by the nervous
system from one's
muscles, joints, tendons and ligaments. It is also known as the "position
sense", which offers a
sense of grounding that is interpreted by the emotional state as perceived
security and/or safety.
Proprioceptive input facilitates the release of serotonin, the master
regulator of the central
nervous system (brain and spinal cord), as well as dopamine. Valued as the
"coping chemical",
serotonin breaks up dopamine thereby preventing hyperactivity and over-
processing of
information, resulting in a neutral state of arousal. Persons having
difficulty processing
1
Date Recue/Date Received 2021-04-09
information from one or both of these systems will demonstrate behaviors that
impede function.
Poor sensory modulation leads to a compromised body system that is interpreted
by the central
nervous system as being "in pieces". The brain and the body will focus on
keeping the
individual's self together, thereby rendering the individual substantially
incapable of efficient
higher cortical function. The basic sub-cortical needs must first be met
before focus can be
diverted to higher cortical function. Maintaining the nervous system at a calm
and alert state is
imperative for cognitive functions and learning.
[0004] Persons affected by impaired function of the nervous system can include
those with
developmental disabilities, Sensory Processing Disorders (SPD), Attention
Deficit Hyperactivity
Disorders (ADHD), Post Traumatic Stress Disorder (PTSD) and autism spectrum
disorders.
Individuals with these conditions have difficulty maintaining homeostasis
within the nervous
system, thereby inhibiting their ability to participate in effective learning
and sometimes causing
behaviors incongruent with social norms. Such identifiable behaviors can
include constant
movement, impulsivity, decreased attention span, inability to focus on a
particular task and
seeking of heavy-pressure related tasks.
[0005] Current treatments for persons affected by an impaired function of the
nervous system
can include pharmaceutical products, behavioral therapy, speech-language
therapy, physical
therapy, play-based therapy, situational therapy and nutritional therapy.
Often in combination,
these forms of treatment can be a tremendous benefit; yet, they are not
without their own
shortcomings. For instance, pharmaceuticals may elicit irresponsive results,
or worse they may
cause adverse side effects for a particular individual. Results from treatment
in general can vary
greatly from one individual to another. Therefore, partially due to the
individualistic nature of
conventional treatment methods, alternative additional forms of treatment were
developed,
including types of treatments utilizing deep pressure and tactile input
therapy.

Date Recue/Date Received 2021-04-09
[0006] Some applications of deep pressure therapy in the prior art include use
of squeeze
machines, weighted blankets, and various weighted articles such as gloves or
vests. These deep
pressure devices have been known to release serotonin, which helps an
individual feel calm and
secure. However, the problem with many of these forms of deep pressure therapy
is that they are
restrictive and can keep the user from fully engaging in daily activities such
as routine tasks,
learning, common social interactions and play.
[0007] What is needed in the art is therapeutic blanket that serves a dual
sensory function with
reference to the proprioception and tactile systems in a healthcare
environment.
SUMMARY OF THE INVENTION
[0008] The present invention relates to a weighted therapeutic blanket that
may be made of
layers of cloth or fabric with specific distributions of weighted elements.
[0009] The present invention provides therapeutic blankets, which are
configured to serve a
dual sensory function with reference to the proprioception and tactile
systems. While the present
invention is beneficial in home, school and community settings, it is
primarily directed for use in
medical and therapy settings, for example, but not limited to: therapeutic
institutional mental
health settings and inpatient and outpatient medical surgery and treatment
settings. The present
invention is beneficial for treatments throughout the lifespan, from birth
through hospice care, of
persons either having neurological disabilities or being neurologically
typical (NT) but
demonstrating anxiety and related conditions. More specifically, the garment
according to the
present invention is a discreet and aesthetically pleasing intervention aimed
at the
neurological/sensory underpinnings contributing to unacceptable sensory-
seeking behaviors in
children and adults with disabilities, and neurologically typical individuals
with situational
anxiety.
[0010] The invention in one form is directed to a therapeutic blanket
including first and second
3
Date Recue/Date Received 2021-04-09
outer layers that are attached together, and an internal matrix of generally
equal sized cells. Each
cell containing a measured weighted mass, the mass being held within the
respective cell. The
matrix being secured to the first and second outer layers along an outer
perimeter of the blanket.
[0011] The invention in another form is directed to a therapeutic blanket
including a plurality
of weighted fabric chains, a bladder, and top and bottom fabric layers. The
bladder has a
plurality of channels therein, with a corresponding one of the fabric chains
being inserted into
each of the channels. The bladder is secured between the top fabric layer and
the bottom fabric
layer along an outer perimeter of the fabric layers.

DETAILED DESCRIPTION OF THE INVENTION
[0043] Referring now to the drawings, and more particularly to Figs. 1-3,
there is shown an
embodiment of the inventive garment 10, which is generally constructed of a
fabric shell 12 that
has a quilted pattern in the form of a plurality of quilted squares 16 for
securing a weighted
filling 14 therein. The garment 10 further includes a pair of curved shoulder
panels 11 and at
6
Date Recue/Date Received 2021-04-09
least one fastener 18.
[0044] The garment 10 is generally configured such that there is a
substantially even weight
distribution within the quilted squares 16 from an anterior side, shown in
Fig. 1, to a posterior
side (not shown) of the garment 10. According to the embodiment shown in Fig.
1, the garment
encompasses the shoulder girdles of a wearer, and it has a contour in the
likeness of a
shoulder cape. The curved shoulder panels 11 allow a clear, defined fit, which
in combination
with the elastic character of the fabric shell 12 maintains the placement of
the garment 10
without inhibiting functional upper-body use of the wearer. Additionally, due
to the snug fit of
the garment 10 around the shoulder girdle, there is a greater surface contact
area for sensory
input. This design ensures accurate and consistent pressure to the body via
the peripheral
nervous system. This even weight distribution provides necessary input to the
surface area of the
mid chest region, shoulder girdle (both anterior and posterior) and upper back
region. Further,
the dermatomes are activated with constant and repeated stimulus each time the
garment is
applied or worn while providing the user with a secure fit that provides a
"hugging" or
compression fit of comfort.
[0045] Fabric shell 12 of the present embodiment is a plush material with a
slight elasticity,
which adds both to the tactile and proprioceptive benefit of the garment 10,
while providing a
comfortable compression fit. The fabric shell 12 houses the weighted filling
14, which can be in
the form of a glass or polymer pellet filling 15 as in the present embodiment,
or in the form of
any other suitable filling that is durable and washable. The fabric shell 12
of the present
embodiment has a quilted pattern in the form of a plurality of quilted squares
16. However, the
fabric shell 12 may have any geometric pattern that equally distributes the
weighted filling 14
throughout the garment 10, including a quilted triangular pattern or a diamond
pattern. Each
quilted square 16 is designed to be substantially the same size and to contain
substantially the
7
Date Recue/Date Received 2021-04-09
same amount of the weighted filling 14. In the embodiment shown in Fig. 1,
each quilted square
16 is 2 'A square inches; however, the size of each quilted square 16 is not
limited to 2 'A square
inches. The quilted squares 16 could be sized in a range from 1 to 3 square
inches. Further, the
quilted geometric pattern may be comprised of various shapes that are not of
equal size.
[0046] The fastener 18 is positioned at the anterior side of the garment 10
such that the wearer
can easily don and doff the garment 10. The embodiment shown in Fig. 1 has a
fastener 18 in
the form of two magnetic fasteners (not shown). Additional possible fasteners
include buttons,
snaps, clasps, laces, Velcro or any other suitable fastener for securing the
garment about the
body of the user. Magnetic fasteners provide simplicity in fastening and they
eliminate the
potential for startling the wearer due to a sudden auditory stimulus, as would
snaps or hook and
loop fasteners. Additionally, magnetic fasteners allow for the garment 10 to
be readily
reversible. The magnetic fasteners are housed within the fabric shell 12, in
other words they are
sewn into the interior of the garment 10, and they do not extend to the
exterior of the garment 10.
Therefore, the wearer's temptation to fidget with the fastener 18 in the
present embodiment is
reduced, allowing the wearer to more easily focus on the task at hand.
[0047] Referring now to Fig. 4, the garment 10 may further include an
integrated hood 20,
which also is constructed of the same plush fabric shell 12 shown in Fig. 3.
The integrated hood
20 includes the weighted filling 14, which is substantially evenly distributed
throughout the
fabric shell 12 of the hood 20. The integrated hood 20 provides an additional
dimension of
sensory input, while maintaining the quilted configuration and cohesive
appearance. It is also
feasible for the integrated hood 20 to be formed as a separate unit, which can
be coupled with the
garment 10 by using an additional fastener or a set of additional fasteners
(not shown). The
additional fasteners may be in the form of magnetics, buttons, snaps, clasps,
Velcro or any
other fastener capable of securing the garment 10 to the hood 20.
8
Date Recue/Date Received 2021-04-09
[0048] Additionally, as illustrated in Fig. 4, a loop 24 may be provided on
the posterior,
bottom edge of the garment. This facilitates a greater sense of independence
because when the
integrated hood 20 is not in use the wearer can easily hang it in his or her
"cubby", locker at
school, or on a hook in a social atmosphere or at home.
[0049] Referring now to Fig. 5, there is shown a second embodiment of the
inventive garment
according to the present invention in the form of an endless loop of fabric
30, which may be
draped about the head, shoulders and neck of the wearer. Garment 30 includes
the fabric shell
12, shown in Fig. 3, which is constructed with a plurality of quilted squares
16, as illustrated in
Fig. 2. The quilted squares 16 include a weighted filling 14, which can be in
the form of a
plurality of glass or polymer pellets (not shown) therein. According to this
second embodiment
of the present invention, the weight of the weighted material 14 is
distributed substantially
evenly across the entirety of the garment 30.
[0050] Referring now to Fig. 6, a third embodiment of the inventive garment is
provided in the
form of a stand-alone hood 40. The hood 40 includes a chinstrap 42 and at
least one fastener 18.
Hood 40 provides proprioceptive input at the crown of the head of a user, via
even disbursement
of weight to the frontal and parietal portions of the cranium. The chinstrap
42 is configured for
applying a predetermined amount of pressure to the temporomandibular joint
(TMJ) when the
chinstrap 42 is fastened under the chin of a user. The TMJ is a site for
sensory stimulation and
organization. A pressure input by the chinstrap 42 advantageously reduces the
quantity and
intensity of maladaptive oral habits, for example, excessive mouthing, teeth
grinding and
chewing on clothing and/or fingers. The fastener 18 can include magnets,
buttons, snaps, clasps,
laces, Velcro or any other suitable fastener for securing the chinstrap 42.
Exemplary uses for
the stand-alone hood 40 may include: (1) Use in transition prior to getting a
child's hair cut; (2)
Calming an otherwise over-stimulated child in a loud, bright community
setting, such as a
9
Date Recue/Date Received 2021-04-09
grocery store, department store or restaurant; (3) Minimizing environmental
input (i.e., light,
noise and movement of peers) from the classroom in a school setting; and (4)
Calming an
overwhelmed child in a social setting with a number of different people and
activities going on
around the user.
[0051] Referring now to Fig. 7, there is shown a fourth embodiment of the
present invention in
the form of a hooded wrap garment 50, constructed of the same fabric shell 12
described above
and having an even distribution of the weighted filling 14. The weighted
filling 14 can be, for
example, a glass or polymer pellet filling (not shown) encapsulated within the
fabric shell 12 for
even weight distribution across the area of the garment 50. The garment 50
further includes a
hood portion 52 and a pair of symmetrical, elongate structural members 54 that
extend outwardly
from the hood portion 52. The extended length of the elongate structural
members 54 provides
additional versatility in how the hooded warp garment 50 is worn because the
elongate structural
members 54 can be extended up to 4 or more feet (ft.). For example, depending
upon the input
desired, the length of the hooded wrap garment 50 may be wrapped or draped
unilaterally or
bilaterally over the shoulders of the user, or may be draped comfortably on
the lap or about the
waist of the wearer when in a seated or reclining position. Upon standing, the
hooded wrap
garment 50 is configured to drape downwardly to the top of the knees of a
wearer, thereby
eliciting a greater pressure input through the shoulders as is promoted by
gravitational effects.
Advantageously, the hooded wrap garment 50 provides flexibility in use and
directed input to the
proprioceptive and tactile sensory systems.
[0052] The hooded wrap garment 50 according to the present invention may also
be configured
without the hood portion as a simple wrap or scarf (not shown). Such a wrap or
scarf can be
wrapped over one or both shoulders, or it may be draped about the neck of the
user to extend
down the back or the front of the body. Reverse wear of such a wrap or scarf,
in other words
Date Recue/Date Received 2021-04-09
with opposing ends extending down the back of the wearer, would elicit a
calming sense due to
the selected proprioceptive and tactile input on the user's nervous system via
providing
substantially uniform weight distribution across the chest and the sternum.
[0053] Referring now to Fig. 8, there is shown a fifth embodiment of the
present invention
configured as a lap pad 60. The lap pad 60 is formed of the same plush,
quilted fabric shell 12
with the weighted filling 14 therein, which is substantially evenly
distributed across the area of
the lap pad 60 for maximum proprioceptive input. The lap pad 60 may be used
simply as a
weighted lap pad or folded in half to increase the weight distribution over a
smaller area, for
example, at the center of the lap of a user. Additionally or alternatively,
the lap pad 60 may be
utilized as a muff when a user's hands are placed between the layers of the
folded lap pad 60,
offering additional proprioceptive and tactile input to the hands, thereby
calming the user. Also,
by positioning the hands of a user within the folds of the lap pad 60, the
upper extremity
tremoring of a user may be dampened, thereby soothing the user through the
enhanced
proprioceptive and tactile inputs on the nervous system.
[0054] Optionally, a plurality of magnetic fasteners (not shown) may be
provided at the
corners of the lap pad 60, affixed within the fabric shell 12. This would
allow the user to secure
the lap pad 60 along a longitudinal axis L or a lateral axis M for increased
versatility in use, as
shown in Fig. 8. For example, the lap pad 60 may be secured around the neck of
a user for
targeted proprioceptive and tactile input to the neck and/or shoulders for a
more proximal
proprioceptive experience. Alternatively, the lap pad 60 may be worn around
the hips as a belt
for proximal stability and input at the pelvic girdle. This is particularly
advantageous for
providing body-awareness for ambulation and gait training.
[0055] Referring now to Fig. 9, a sixth embodiment of the present invention
provides a
perimeter blanket 70, which includes a central panel 71 and a perimeter area
72 formed by the
11
Date Recue/Date Received 2021-04-09
fabric shell 12, which is illustrated in Fig. 3. The perimeter area 72 further
includes a plurality of
quilted squares 74 that house the weighted filling 14, which is substantially
uniformly distributed
throughout the fabric shell 12. Perimeter area 72 outlines the central panel
71, which is also
formed of the same plush fabric as perimeter area 72, for a calming input into
the tactile sensory
system. Advantageously, since the quilted squares 74 are positioned about the
perimeter it
allows the user to selectively distribute the weight to provide a desired
amount of pressure and
tension across selected areas of the body, thereby allowing the user to define
the desired
proprioceptive input into the nervous system. The perimeter blanket 70 thereby
provides both
weight and compression when draped and/or wrapped about the body with varying
degrees of
tension. Further, because of the unique design and weight distribution, the
perimeter blanket 70
will not shift off of a user's lap or body, despite active movement.
[0056] The perimeter blanket 70 may further optionally include, encased within
the fabric shell
12, a plurality of magnetic inserts 76 having respective alternating
polarities positioned around
the periphery of the perimeter blanket 70 such it may be gathered up into a
sack or a bag for a
variety of uses.
[0057] Referring now to Fig. 10, there is shown a seventh embodiment in the
form of
proprioceptive and tactile input bands 80, which may be positioned about the
wrists or ankles of
a user. The bands 80 include the plush fabric shell 12, the weighted filling
14 and a fastener
configured as a plurality of magnets 82. Provided in varying widths and
lengths, the bands 80
offer proprioceptive input for a number of functional activities, for example,
handwriting and
fine-motor activities when positioned about the wrists. The magnets 82 are
hidden within the
fabric shell 12 and are positioned at opposing ends within contiguous quilted
squares (not
shown), such that bands 80 may be folded lengthwise for a greater intensity of
weight
distribution. The plush fabric shell 12 has a slight elasticity that offers an
additional sensory
12
Date Recue/Date Received 2021-04-09
component of compression, depending upon the tension applied to bands 80 in
positioning them
about the body.
[0058] According to the present invention, additional optional accessories may
be utilized in
association with any of the above-referenced embodiments of the present
invention. For
example, magnetic patches 90 (see Fig. 11) may be secured to any of the above-
identified
embodiments using a fastener 18. Such magnetic patches 90 may be used to
provide visual or
tangible recognition of tasks accomplished throughout the user's day. These
tasks may include
visual presentations of information such as emotional status, functional
prompts for visual
sequencing, self-help and/or daily skills and routines, sports, therapy
sessions, etc.
[0059] Also, an additional accessory in the form of a purse 92 (see Fig. 11),
bag or backpack
(not shown) may be provided in a matching fabric pattern to be utilized in
association with the
above-identified inventive garments, thereby providing an aesthetically
pleasing, socially
acceptable or normalized and fashionable set, while also meeting the
specialized neurologic
needs of the user. Selective weighting of the purse 92, bag or backpack may be
provided such
that the fashionable accessory can be converted for purposes of selective
proprioceptive input at
predetermined points across and around the user's body. The purse 92, bag or
backpack may
also be provided with overlapping magnets (not shown) on the straps to offer a
safety release
feature.
[0060] Referring to Fig. 12, another accessory is shown as an inventive
therapeutic fidget 100.
The fidget 100 includes a plurality of square linear magnets 102 positioned
within a plurality of
quilted fabric squares 104, which aid in self-regulation of a user to calm and
organize the
nervous system. By actively grasping and pulling the magnetic strips 102
apart, tensile qualities
of the fidget 100 engage receptors of the nervous system and thereby provide
the desired
proprioceptive, auditory and tactile inputs. Likewise, the alternating
alignment of the magnets
13
Date Recue/Date Received 2021-04-09
102 piques the interest of the user by experiencing proprioceptive input via
the
"repelling/oppositional" forces. As can be seen in Fig.12 each of the fabric
squares 104 are
coupled to at least one other fabric square 104, each having magnets 102
centrally located within
fabric squares 104. Each magnet 102 has a corresponding shape with the other
magnets 102.
Fig. 12 also illustrates that the fabric squares 104 form a linear array of
fabric squares, with each
of the fabric squares 104 have no more than two other fabric squares 104
adjacent thereto.
[0061] Also along these lines, Fig. 13 illustrates another inventive accessory
in the
configuration of a crown headband 110. The crown headband 110 provides
selective pressure at
a plurality of points around the head, giving the wearer a fitted, compression-
like feel.
Circumferential input to the area just above the supra-orbital processes
provides direct
neurological benefits. These benefits can include activation of the body's
Labyrinthine righting
reflex and proprioceptive balancing. With such neuromuscular re-education,
postural alignment
can be obtained via activation of the spinal nerves, enhancing the body's
capacity for higher
cortical learning.
[0062] In addition, according to the present invention, there is provided a
magnetic book (not
shown) that includes a plurality of magnets positioned at a perimeter of a
plurality of pages to
provide positive intensity resistance, while fostering literacy and functional
communication
skills. The magnetic book of the present invention may be utilized to provide
the user with
visual clues to allow the user to participate in their day with greater
independence. Visual
supports are graphic clues that can be used to aid communication between the
caregiver and the
patient or user of the book. The inventive magnetic book may also be used as
an environmental
prompt that aids a child in remembering what is expected of them in a certain
activity or routine.
The invention may be modified to meet the needs of (1) Social stories in the
form of a
personalized reference to daily routines and activities, providing comfort and
assistance in
14
Date Recue/Date Received 2021-04-09
memory and self-regulation; (2) Visual schedules by laying out the events of a
day or routine,
one-by-one, and by giving a clear sense of the sequence and expectations of
the day; (3) First-
Then Boards which show the sequence of events and teach that in order to get a
reward the child
or patient must sometimes perform a less favorable activity first; and (4)
Choice Boards which
provide different options of what a child would like to do within activities
and routines, thereby
helping a user to focus on appropriate options and efficient communication of
desires.
[0063] Now, additionally referring to Fig. 14, there is shown another
embodiment of the
present invention in the form of a weighted blanket 170 that is similar to
perimeter blanket 70,
but having a complete array of quilted squares 174 each having weighted
fillings 176 therein.
The weighted fillings 174 are substantially uniformly distributed throughout
the fabric shell.
Advantageously, since the quilted squares 174 are positioned in the form of an
array it allows the
user to selectively distribute the weight to provide a desired amount of
pressure and tension
across selected areas of the body, thereby allowing the user to define the
desired proprioceptive
input into the nervous system. Blanket 170 provides both weight and
compression when draped
and/or wrapped about the body with varying degrees of tension. Blanket 170 may
further
optionally include, encased within the fabric shell, a plurality of magnetic
inserts 176 having
respective alternating polarities positioned around the periphery of blanket
170 such it may be
gathered up into a sack or a bag for a variety of uses.
[0064] Now, additionally referring to Figs. 15 and 16 there are shown other
variants of the
present invention in the form of a layered fabric item 200, where an array
202, of twenty-four
filled elements 204, which can include substantially equal amounts of glass or
polymer pellets,
are shown in Fig. 15 and an array 206 of sixteen filled elements 204 are shown
in Fig. 16.
Considering the arrangement of Fig. 15, array 202 can be considered to have
three linear arrays
208, 210 and 212, each with eight elements 204. In a similar fashion, fabric
item 200 can have
Date Recue/Date Received 2021-04-09
two linear arrays 214 and 216 that are arranged in array 206. Here fabric item
200 has two outer
fabric layers 218 and 220 that are used to enclose array 206. While it is
contemplated that
elements 204 can be arranged as individual elements that are then positioned
and individually
secured to fabric layers 218 and 220, it is also considered that linear arrays
of elements 204 are
manufactured and arranged side-by-side and attached to fabric layers 218 and
220 to form a
finished fabric item 200. Fabric layers 218 and 220 are secured to each other
and may be
secured through array 206 to form a quilted appearance. It is also
contemplated that selected
seams may be used to secure linear arrays 214 and 216 to layers 218 and 220.
[0065] Each filled element 204 can have a weighted filling 222 therein or item
222 can be
magnets 222 having magnetic polarities that are arranged for specific
purposes. For example, in
fabric item 200 (which can also be called a fidget 200), each magnet 222 in
linear array 214 can
be arranged to have the same or opposing polarities as the immediately
adjacent magnet 222.
For purposes of explanation each element in linear arrays 214 and 216 are
assigned positions a-h
therein, and will be referred to as magnet 214a through 216h, and the
polarities will be referred
to as North (N) facing out of the page or South (S) facing out of the page.
One conceived pattern
is for magnet 214a to be N and magnet 214b to be S and this alternating
pattern continues along
linear array 214; and that magnets 216a-h be arranged in a contra pattern of S-
N-S-N-S-N-S-N.
In this pattern each magnet 222 will be an opposite polarity to its adjacent
neighbor. With this
arrangement fidget 200 can be folded along the numerous intersections between
elements 204 in
various ways with the attractive magnetic forces arranging a centering and
coupling of each fold.
The fidget 200 presents a therapeutic interest for the user, to arrange,
rearrange and flip the fidget
around to investigate the various ways that it can be arranged, providing
physical therapeutic
possibilities for the hands, eye-hand coordination exercises and interest to
occupy the mind.
[0066] Now, additionally referring to Figs. 17 and 18, there is shown yet
another embodiment
16
Date Recue/Date Received 2021-04-09
of the present invention in the form of a blanket 250 having outer fabric
layers 252 and 254 that
are arranged to have channels 256 and 258 formed therein by seams 260 that
proceed along a
length of blanket 250 with an end seamed piece 262 and a side seamed piece 264
finishing the
look of blanket 250. While, for purposes of illustration, two channels 256 and
258 are shown,
there are channels all along the width of blanket 250.
[0067] Now, additionally referring to Figs. 19-23, there are shown the steps
of making blanket
250, as well as the internal structure thereof. Linear arrays 266 of filled
elements (weighted
sections) 204 are arranged to be pulled into each channel 256/258 using a
pulling device 268.
Pulling device 268 is a stiffened yet flexible item that is pushed through
each channel 256/258 to
which each linear array 266 is temporarily coupled and the pulling of device
268 allows each
linear array 266 to be positioned in a respective channel, as shown in Figs.
19 and 20. As shown
in Fig. 21 linear arrays 266 have been positioned in each channel of blanket
250, and are
arranged so that an end of each linear array 266, as shown in Fig. 22, is
positioned at an end of
each channel 256/258, so that end piece 262 can be seamed, at each end of
channel 256/258, to
thereby captivate the ends of each linear array 266 to fabric layers 252 and
254.
[0068] Now, additionally referring to Figs. 24-29, there are shown elements of
a therapeutic
blanket 300 along with the details of steps taken to make therapeutic blanket
300 of the present
invention. Glass beads 320 are added to each square 314 and then square 314 is
closed with an
ultrasonic weld, not stitching. Fig. 24 illustrates a filling chain group 302
of three chains 304
that are being cut from group 302. Chains 304 are referred to that in this
embodiment of the
present invention and each square 314 can be considered a link 314 in the
linear chain 304.
When chains 304 are cut from group 302 approximately one half inch of edge
material 306 is left
along each side of each chain 304.
[0069] Edge material 306 is folded onto chain 304 as chain 304 is inserted
into a bladder 308,
17
Date Recue/Date Received 2021-04-09
as illustrated in Fig. 25. Bladder 308 has channels 310 that are defined by
the space between
seams positioned approximately 2 inches apart on two pieces of fabric that are
formed into
bladder 308. Chains 304 are inserted into channels 310 by first inserting Pull-
through Rods into
the channels 310 of bladder 308 and an end of each chain 304 is hooked to each
pull-through
rod. The pull-through rods are then withdrawn thereby pulling chains 304 into
channels 310,
with edge material 306 being drawn in in a folded over condition. Edge
material 306, which can
be considered a 'A inch fold over is important because it helps keep chain 304
in place and not
twist around as chain 304 is drawn into channel 310. Further, because of the
nature of the
medical grade fabric used in blanket 300, the position and folded nature of
edge material 306
provides extra cushion in blanket 300. As bladder 308 is filled with chains
304 it becomes a
bladder assembly 312.
[0070] Bladder assembly 312 is illustrated with a top view in Fig. 26 and a
bottom view Fig.
27. Links 314 form a matrix M of links 314 or cells 314. Chains 304 as well as
fabric layers 316
and 318 of bladder 308 may be made of a fabric, such as brushed tricot. At
this point in the
making of blanket 300, there are 4 layers of brushed tricot (the two layers
that form chains 304
and layers 316 and 318 + the fold-over edge material 306 + the beads 320 in
the 2 inch squares
314 with the specific bead weight in each link 314.
[0071] Outer shells 322, made of antimicrobial fabric, such as Fusion III
fabric are place on
both sides of bladder assembly 312 to thereby result in a total of 6 layers of
fabric (4 brushed
tricot + 2 Fusion III). Fabrics 322 and bladder assembly 312 are aligned to
prepare for sewing
with a baste stitch. It is also contemplated that an ultrasonic welding
technique could be used
instead of using sewn stitching. Then after a baste stitch is sewn around
entire periphery edge, or
the perimeter of blanket 300, an overlock stitch is sewn around the perimeter.
A binding 324 is
then folded over the perimeter and is sewn onto therapeutic blanket 300.
Binding 324 can be
18
Date Recue/Date Received 2021-04-09
made of 210 D antimicrobial fabric. As illustrated in Figs. 28 and 29, blanket
300 has rounded
corners. Further, there are no stitches on the main body of the item, so that
the product is smooth
and able to be wiped clean per the medical protocols in use at hospitals and
other medical
facilities.
[0072] The present invention uses glass beads that are chosen with a specific
size of between
2.85 mm and 3.45 mm and are nominally spherical of approximately 3 mm in
diameter so that
they provide the correct weight in the range of 0.1 Oz. to 0.4 Oz. per 2 inch
square, which results
in the desired density for each 2" square. Different fill weight selections
are generally set at 1, 2,
3 or 4 tenths of an ounce per square of 2 inches to achieve different weights
per square inch
depending on the size of the item and the needed therapeutic input.
[0073] The importance of bead fill with dimensional size products is that it
is not just a heavy
weight. It is that the placement of weight must be done in the right way with
the right amount of
weight to promote nerve contact and activation. In other words, the
combination of size of
square, weight per square inch, size of the bead, and density of bead.
[0074] Smaller dimensional size product = less nerve contact area = more
weight per square
inch to produce Deep Touch Pressure to activate the nerve.
[0075] Larger dimensional size product = more nerve contact area = less weight
per square
inch needed to produce Deep Touch Pressure to activate the nerve.
[0076] Purdue Northwest University and Parkview Health System have conducted a
study
using the present invention. The study was conducted by Jamie Vinson BSN, RN,
FIN-BC,
RYT, the following is mainly the results of that study.
[0077] A bedside nurse was inspired to investigate a complementary
intervention, historically
used to reduce anxiety and agitation in children on the Autism spectrum, for
the use of anxiety
reduction in adults receiving their first and second outpatient chemotherapy
infusions. A
19
Date Recue/Date Received 2021-04-09
research study was conducted that compared the effectiveness of weighted
blanket intervention
to no blanket intervention in the reduction of anxiety for patients receiving
their first two
outpatient infusion visits. Anxiety management is often treated with
pharmacological measures.
This patient -centered innovation gives the patient and nurses a non -
pharmacological
intervention option to help reduce the patient's anxiety. Comments received
from patients about
the weighted blanket were overwhelmingly positive. This simple intervention
may also lead to
an improved patient experience and/or less need for pharmacological
interventions for anxiety.
[0078] Weighted blankets have been used as a way of delivering Deep Touch
Pressure (DTP)
to those suffering from autism, ADHD, PTSD, bipolar disorder and insomnia by
both
occupational therapists and caregivers to help reduce anxiety, increase focus,
and promote rest.
Weighted blankets have more recently been used to reduce anxiety in painful
dental procedures.
Some cancer patients experience increased anxiety when receiving chemotherapy
infusions.
There is a lack of research on the effectiveness of weighted blankets as an
intervention for
anxiety reduction in patients who are receiving chemotherapy infusions.
[0079] A randomized, controlled, crossover study used each patient as their
own control to
evaluate the effects of weighted blankets on anxiety in outpatient infusion
center patients
receiving their first and second chemotherapy infusions.
[0080] Data collection at admission included: demographics, vital signs, State-
Trait Anxiety
Inventory for Adults form Y1 (STAIAD-Y1), and Visual Analog Scale (VAS).
[0081] Data collection at 30 (+/-5) minutes from when the weighted blanket was
placed or
from when the admission VAS for anxiety was marked by the patient included:
vital signs,
STAIAD-Y1, and VAS.
[0082] Data collected at patient discharge included: vital signs, VAS and
patient/nurse
comments.

[0085] When a weighted blanket was used, patient STAIAD-Y1 scores were reduced
by an
additional 2.15 (95% CI 4.05, 0.25) on average compared to those where it was
not.
[0086] Weighted blanket use was associated with a mean 8.89 (95% CI 16.59,
1.18) point
additional reduction in VAS scores at the half-hour mark.
[0087] The correlation analysis of VAS and STAIAD-Y1 scores showed a strong
positive
correlation between the two scores.
[0088] There were no adverse events with the use of the weighted blanket.
[0089] The majority of nurses and patient comments about the weighted blanket
were positive.
[0090] The Purdue Northwest University and Parkview Health System study found
that
STAIAD-Y1 and VAS anxiety decreased more with the use of the weighted blanket.
The study
also concluded that under an adjusted linear mixed-effects model, including
STAIAD-Yl and
VAS anxiety, the overall anxiety of the patient also decreased more with the
use of the weighted
blanket. The study also found that STAIAD-Y1 and VAS anxiety correlate with
one another.
Therein, a higher STAIAD-Yl score correlates with a higher VAS anxiety score.
[0091] Weighted blankets may be used as a complementary intervention for
reducing anxiety
21
Date Recue/Date Received 2021-04-09
in patients receiving chemotherapy.
[0092] A standard weight medical-grade therapeutic weighted blanket can be
safely used in the
adult population.
[0093] A visual analog scale is a valid tool to measure anxiety compared to
STAIAD-Yl.
[0094] Patients and nurses enjoyed using the weighted blanket as an
intervention to help
reduce anxiety. (end of 1st study excerpt).
[0095] In a subsequent article the author of the study indicated:
[0096] Initially, CapeAble (owner of the present invention) donated three
blankets for me to
trial in the hospital. Then Amy Poole, director, Oncology Services, asked The
HOPE Foundation
to donate enough money for us to purchase five medical-grade weighted blankets
from
CapeAble.
[0097] I learned two important things (from the study): 1) These patients
experienced a
reduction in anxiety through weighted blanket therapy, and 2) You can
effectively use the same
blanket on patients of all weights. It is not the total weight of the blanket
that matters, it is the
amount of Deep Touch Pressure (DTP) the blanket delivers (ounces per square
inch). This means
that there is no need for multiple "weights". We can use a standard weight
medical-grade
therapeutic weighted blanket for patients of many shapes and sizes. This will
change the current
guidelines of the weighted blanket industry.
[0098] I (received) the American Holistic Nurses Association Research Grant
Award this year
and have also received funding from the Parkview Foundation. The next step
will be to research
whether weighted blankets can reduce pre-surgical pain and anxiety, and
postsurgical
restlessness, nausea and vomiting. Quality Improvement (QI) projects using
weighted blankets
are also underway here at Parkview. Nurses and patients are seeing amazing
results. I am always
hearing the testimony of how well the weighted blanket has worked in all sorts
of scenarios. I
22
Date Recue/Date Received 2021-04-09
would like to be the first hospital to implement weighted blankets as a
standard of care for all
patients in the health system. (end of excerpt).
[0099] In a recent study (2nd study herein) of the therapeutic blanket of the
present invention
carried out by Hannah Rawlinson, she stated that - Application of a CapeAble
(owner of the
present invention) weighted blanket to create DTP to improve quality of sleep.
CapeAble
weighted blankets were donated for the use of this project. The focus is on
neuroscience and
neurological response to maximize complete nerve contact through the weighted
blanket
(Pacheco, 2018). The blankets are unique in their structure, providing evenly
distributed weight
over the entire body. The difference in CapeAble weighted blankets compared to
weighted
blankets that have been used over the past 30 years is their ability to use
less weight more
effectively. These medical grade blankets are designed with 0.20 ounces per
two-inch square
pocket of glass beads (Pacheco, 2018). This design does not allow for the
weight within the
blanket to shift. When the blankets are applied to patients, the blanket is
able to conform to any
shape or size body. The blanket compresses evenly and stays in direct contact
with the patient's
nerves. By stimulating the ANS through DTP, it signals the brain to release
calming chemicals
and endorphins (Pacheco ,2018). CapeAble weighted blankets are easily
manipulatable and
gentle on the patients. Medical grade CapeAble weighted blankets come in three
sizes; small,
medium, and [twin]. Blanket size is chosen based on age, size, frailty, and
diagnosis. (end of 2'd
study excerpt).
[00100] The present invention is a therapeutic blanket 300 and includes first
and second outer
layers 322 that are attached together. An internal matrix M of generally equal
sized cells 314 lies
between layers 322. Each cell 314 containing a measured weighted mass 320, the
mass 320
being held within the respective cell 314. The matrix M is secured to the
first and second outer
layers 322 along an outer perimeter binding 324 of blanket 300. As
illustrated, matrix M is only
23
Date Recue/Date Received 2021-04-09
secured along the outer perimeter and is not otherwise attached to layers 322.
The mass of each
measured weighted mass is substantially similar, and matrix M extends
substantially to the outer
perimeter of the first and second outer layers 322. The mass of each measured
weighted mass
320 is within the range of 0.1-0.4 Oz. with the preferred fill being
approximately 0.2 Oz.
[00101] Each cell 314 is approximately four square inches in area, with the
width and length
that are approximately equal, of approximately 2 inches. Each cell 314 of
chain 304 of matrix M
is configured to be sequentially sealed after a preselected amount of the
weighted mass 320 that
includes glass or polymer pellets 320 is inserted therein.
[00102] First outer layer and the second outer layer 322 is an anti-microbial
fabric. The
matrix M is a bladder assembly 312 that includes a series of weighted chains
304 pulled into
channels 310 of a bladder 308. Weighted chains 304 have an edge material 306
that is folded
over on each chain 304 within the channel 310 in which the chain 304 is
placed.
[00103] Another way of considering therapeutic blanket 300 is that it includes
a plurality of
weighted fabric chains 304, a bladder 308 having a plurality of channels 310
therein. A
corresponding one of the fabric chains 304 are inserted into each of the
channels 310. Top fabric
layer 322, bottom fabric layer 322, and the bladder 308 are secured together.
The bladder 308
being between the top fabric layer 322 and the bottom fabric layer 322 along
an outer perimeter
324 of fabric layers 322.
[00104] Each of the plurality of chains 304 have a portion 306 along the
length of the chain
304 that is folded over as chain 304 is inserted into the associated channel
310. Each chain 304
is secured to bladder 308 and bladder 308 is secured to fabric layers 322
along perimeter 324 of
fabric layers 322.
[00105] While this invention has been described with respect to at least one
embodiment, the
present invention can be further modified within the spirit and scope of this
disclosure. This

adaptations of the invention
using its general principles. Further, this application is intended to cover
such departures from
the present disclosure as come within known or customary practice in the art
to which this
invention pertains.
