There is
an invisible problem among people with spinal cord injuries.
Paraplegics and quadriplegics are plagued by pressure sores (decubitus
ulcers) because the loss of feeling and mobility in the lower body.
These ulcers result from lack of circulation due to pressure on the
soft
tissues. Ulcers can be large and can extend to the bone. Typically,
post
surgical confinement to bed degrades the health of the patient,
beginning a downward health spiral. Several products exist that delay
the formation of sores, but currently there is no clinically tested
product on the market that prevents their formation.
Care for pressure sores in general is a major expense, estimated at
$3-5 billion a year in the US. People who use a wheelchair for more
than eight years have a better than 80% chance of developing at least
one pressure sore. Over 60,000 deaths annually in the US are attributed
to pressure sore complications.
An average hospital stay of 90 days is required for a typical severe
sore.
To address the problem of pressure sore formation,
Aqua-Aire
Cushion designed and built a seat cushion to prevent pressure sores.
Improving reliability and safety. The cushion works by migrating
water and air through a bladder virtually eliminating shear force and
pressure on the user.
Thus, the seat itself shifts the weight
distribution. Optimization of materials, fabrication method, all attribute to
potential
applications that extend past the prevention of pressure sores to
reduction of fatigue in professions that require long periods of
sitting,
such as truck driving ad even office work.
