DETAILED DESCRIPTION OF THE INVENTION
[0015]
While the making and using of various embodiments of the present invention are
discussed in detail below, it should be appreciated that the present invention
provides many
applicable inventive concepts that may be embodied in a wide variety of
specific contexts. The
specific embodiments discussed herein are merely illustrative of specific ways
to make and use
the invention and do not delimit the scope of the invention.
[0016] An
eye examination is a series of tests performed by an ophthalmologist (medical
doctor), optometrist, or orthoptist assessing vision and ability to focus on
and discern objects, as
well as other tests and examinations pertaining to the eyes. Health care
professionals often
recommend that all people should have periodic and thorough eye examinations
as part of
routine primary care, especially since many eye diseases are asymptomatic.
[0017] Eye
examinations may detect potentially treatable blinding eye diseases, ocular
manifestations of systemic disease, or signs of tumours or other anomalies of
the brain.
[0018]
Ideally, the eye examination consists of an external examination, followed by
specific tests for visual acuity, pupil function, extraocular muscle motility,
visual fields,
intraocular pressure and ophthalmoscopy through a dilated pupil.
[0019] A
minimal eye examination consists of tests for visual acuity, pupil function,
and
extraocular muscle motility, as well as direct ophthalmoscopy through an
undilated pupil.
[0020]
Close inspection of the anterior eye structures and ocular adnexa are often
done with
a slit lamp which is a table mounted microscope with a special adjustable
illumination source
attached. A small beam of light that can be varied in width, height, incident
angle, orientation
3
SUBSTITUTE SHEET (RULE 26)
CA 03002845 2018-04-20
WO 2017/070374 PCT/US2016/057955
and colour, is passed over the eye. Often, this light beam is narrowed into a
vertical "slit", during
slit-lamp examination. The examiner views the illuminated ocular structures,
through an optical
system that magnifies the image of the eye and the patient is seated while
being examined, and
the head stabilized by an adjustable chin rest.
[0021] This allows inspection of all the ocular media, from cornea to
vitreous, plus
magnified view of eyelids, and other external ocular related structures.
Fluorescein staining
before slit lamp examination may reveal corneal abrasions or herpes simplex
infection.
[0022] The binocular slit-lamp examination provides stereoscopic magnified
view of the
eye structures in striking detail, enabling exact anatomical diagnoses to be
made for a variety of
eye conditions.
[0023] Also ophthalmoscopy and gonioscopy examinations can also be
performed through
the slit lamp when combined with special lenses. These lenses include the
Goldmann 3-mirror
lens, gonioscopy single-mirror/ Zeiss 4-mirror lens for (ocular) anterior
chamber angle structures
and +90D lens, +78D lens, +66D lens & Hruby (-56D) lens, the examination of
retinal structures
is accomplished.
[0024] Intraocular pressure (lOP) can be measured by Tonometry devices. The
eye can be
thought of as an enclosed compartment through which there is a constant
circulation of fluid that
maintains its shape and internal pressure. Tonometry is a method of measuring
this pressure
using various instruments. The normal range is 10-21 mmHg.
[0025] Some of these types of eye examinations include placing the chin of
a patient on a
chin rest within a support device and then measuring the eye sight. However,
most chin rests

CA 03002845 2018-04-20

within standard support devices do not adequately support larger patients.
Thus, this type of
patient feels uncomfortable when the chin is placed on the chin rest of the
device. For example,
bigger patients have to squeeze their upper body into the support device in
order to place their
chin on the chin rest which can be very uncomfortable to the patient.
[0026] Therefore, a need exists for a chin rest within a support device
that is comfortable
for larger patients, as well medium sized patients, to place their chin on the
chin rest for the eye
examination. The present invention has an advantage to solve this need.
[0027] Now turning to Figure 1, an embodiment of the present invention is
illustrated. In
this embodiment, a chin rest and head support system 100 is shown attached to
table 102. In
turn, a support level 104 is attached to the table 102 along with a medical
eye testing device 106.
The eye testing device 106 is positioned adjacent to the support system 100 in
order to allow an
eye professional/technician to exam a patient. The support system 100 includes
a left support bar
108 as well as a right support bar 110. Also shown in this figure, is a left
handle 112 near the
bottom of the left support bar 108. Similarly, a right handle 114 near the
bottom of the right
support bar 110 is shown.
[0028] Also shown in this figure is a chin rest 116 attached near the
center of curved chin
bar 118. The curved chin bar 118 is attached to the right support bar 110 as
well as the left
support bar 108. At the juncture where the curved chin bar 118 is attached to
the right support
bar 108, a mechanism 120 allows the curved chin bar 118 to adjust vertically
as may be required
for the comfort of the patient to be examined. In addition, the head rest 122
is shown attached to
the right support bar 110 as well as the left support bar 108. Moreover a
handle 124 is shown
that may be used to grip the support system 100 in order to reposition or move
the support

system 100.
[0029] Figure 2 illustrates the support system 100 from a side view. In
this figure, the grip
124 is shown attached to the right support bar 110 which includes the
adjustment mechanism 120
and the right handle 114. In addition, the head rest 122, the chin rest 116
and curved chin bar
118 along with the eye testing device 106 and the support level 104 are shown.
[0030] Figure 3 illustrates a different perspective of the support system
100 from a rear/side
view. In this figure, a chin rest and head support system 100 is shown
attached to table 102,
which in turn is on top of an additional table 126. However, in other
embodiments, the table 102
and the additional table 126 can be combined as well as other configurations
of similar supports
can be utilized.
[0031] Moreover, a support level 104 is attached to the table 102 along
with an eye testing
device 106. Similar to Figure 2, the eye testing device 106 is positioned
adjacent to the support
system 100 in order to allow an eye professional/technician to exam a patient.
Additionally, the
support system 100 includes the left support bar 108 as well as a right
support bar 110. Also
shown in this figure, is the left handle 112 near the bottom of the left
support bar 108. Likewise,
the right handle 114 near the bottom of the right support bar 110 is shown.
[0032] Also shown in this figure is the chin rest 116 attached near the
center of the curved
chin bar 118. The curved chin bar 118 is attached to the right support bar 110
as well as the left
support bar 108. At the juncture where the curved chin bar 118 is attached to
the right support
bar 108, the adjustment mechanism 120 allows the curved chin bar 118 to adjust
vertically as
shown in Figure 1. In addition, the head rest 122 is shown attached to the
right support bar 110

as well as the left support bar 108. Moreover the handle 124 is shown that may
be used to grip
the support system 100 in order to reposition or move the support system 100.
[0033] Figure 4 illustrates a detailed view of the adjustment mechanism 120
that allows the
chin rest 116 and the curved chin bar 118 vertically adjust as desired by the
eye
professional/technician and/or the patient. In this figure, the head rest 122,
the right support bar
110, as well as the eye testing device 106 are shown.

embodiment, the support system 100 includes the left support bar 108, the
right support bar 110,
the curved chin bar 118, the chin rest 116, the left handle 112, the right
handle 114, the head rest
122 and the handle 124. In this embodiment, similarly to figure 3, the support
system 100 is
shown attached to table 102, which in turn is on top of an additional table
126. However, in
other embodiments, the table 102 and the additional table 126 can be combined
as well as other
configurations of similar supports can be utilized. In addition, this
embodiment includes an
adjustment bar 128 which elevates the chin rest 116 as desired by the eye
professional/technician
and/or the patient.
[0035] Figure 6 illustrates a side view of embodiment of Figure 5. Similar
to the first
embodiment, the support system 100 includes the right support bar 110, the
curved chin bar 118,
the chin rest 116, the right handle 114, the head rest 122 and the handle 124.
In this
