February 6, 2015 and U.S. provisional patent application number 62/122,467
filed on October
22, 2014,
FIELD OF THE EMBODIMENTS
The invention and its embodiments relate to medical devices, namely a device
that is
capable of alleviating lower back pain. In particular, the present invention
and its embodiments
relate to a device that prevents the lumbar spine process and its peripheral
nerves from being
touched or compressed.
BACKGROUND OF THE EMBODIMENTS
There are about 150 - 200 million adults that suffer from low back pain in
United States,
and it is the second most common reason people seek a doctor. This health
problem results in
about 2.4 million Americans chronically disabled and temporarily on
disability. Lower back pain
affects the spine's stability, flexibility, and strength as result cause pain,
discomfort and stiffness
during daily living activities such as sitting, driving or sleeping. A great
majority of back pain
experienced by the general population occurs in the lower portion of the back
generally referred
to as the lumbar area or the spinal segments L-3 through S-1 specifically. In
order to comprehend

the most causes of low back pain, it is essential to understand the
functioning of the spinal
column. The purpose of the human spinal column is to support and protects the
body. The most
common area of low back pain is at the spinal process segment L-3 to S-1. The
spine process is
composed of twenty four individual vertebrae. Each vertebra is attached and
support by
cartilages, muscles and ligaments to allow flexibility to bend over, and to
rotate the torso. Each
vertebra is connected by an intervertebral disc that functioning to provide
cushion, and prevent
compression to the peripheral spinal nerves. Whenever there is a shift of the
vertebrae from its
normal position caused by herniated discs, spinal stenosis, fractures,
osteoarthritis or injury, it
presses against the spinal nerves, and as a result it stimulates pain during
daily living activities
such as a sitting, sleeping, driving or bending. Likewise, low pain back is
also caused by, the
shifting of the 2 vertebrae caused by unequal pressure of the muscles
supporting the spine
column. This can occur due to overuse or injury of the muscles or ligaments,
uneven muscular
stress, emotional tension. The majority of low back pain is managed with
conservative treatment
such as rest, analgesic, anti- inflammatory medications in conjunction with
physical therapy to
strength the back muscles to support the spine column to relief pain or
eliminate it. Another
conventional treatment used to address back pain due to injury or non- injury
is applying
pressure to the area with orthopedic belt devices.

to be limited thereto. In fact, those of ordinary skill in the art may
appreciate upon reading the
present specification and viewing the present drawings that various
modifications and variations
can be made thereto.
Low Back Pain solution device features two main components: the outside
envelope and
the back section. These components can be constructed from, by non-limiting
example ethyl
vinyl acetate (EVA) or nitrile butadiene rubber foam. In one embodiment, the
back section is a
single piece shaped similarly to a human buttocks. In a preferred embodiment,
the back section
features two cushion pads, as well as a cavity. Preferably, this cavity will
be 6 centimeters wide.
The purpose of this cavity is to protect the spinal column and peripheral
nerves from being
touched or compressed by any object. Objects that can frequently cause such
touching or
compression include chairs, sofas, beds or car seats. This function also
prevents pressure against
incision site of post-spine surgery individual or individual with injured
back. It allows the
individual to perform daily activities such as sleeping, sitting or driving.
Further, any spinal incision is protected from being touched by any object
during the
above activities, which makes a user's healing process fast and effective. In
turn, this makes the
recovery period shorter. Another significant feature of this device is the two
soft yet firm
cushioned pads. Preferably, these pads have rectangular base with a rounded
top, however, this
does not mean that other shapes would not be suitable. This rounded top lies
on the erector
spinae muscles allowing the spine process and its nerves to be free from
contact due to any
object. In a preferred embodiment, these pads are aligned parallel to a user's
lower spine
processes and erector spinae musculature. These pads hold the muscles in place
to support the
spine; allowing good blood flow to the area, and it prevents the muscles to
fatigue, which also
promotes healing.
