Description

Shape-adjustable pressure ulcer prevention cushion and its adjustment method The present invention relates to a pressure sore prevention cushion that can adjust the shape of the seat. Spinal cord injury is a representative condition of severe disability. Individuals with severe spinal cord injuries experience a decline in physical function due to paralysis depending on the location of the injury, making it difficult to participate in various activities. In particular, for those with severe disabilities, such as spinal cord injuries, whose sensory functions are impaired along with motor functions following the injury, their limbs are at risk if they do not exercise special caution. Individuals with severe spinal cord injuries who have limited sensory function in their limbs generally use electric wheelchairs, and they utilize cushions to reduce pressure concentrated on their buttocks when sitting for long periods. These cushions are commonly referred to as "bedsore prevention cushions," and inflatable cushions are sometimes provided as assistive devices for the disabled. The ‘offloading pressure sore prevention cushion’ has the same purpose of preventing pressure sores, but while the main pressure sore prevention cushion is inflatable, the offloading pressure sore prevention cushion mentioned in the present invention is manufactured in a form that includes a seat portion with adjustable shape instead of being inflatable. In the present invention, ‘offloading’ refers to a method of reducing the pressure applied to the buttocks to off, or close to zero, by dispersing the pressure on the protruding parts of the ischium (hip bone) where pressure is applied while sitting on a pressure measuring sensor (body pressure sensor) to reduce pressure concentration, and allowing the pressure to be absorbed more by the parts with relatively more surrounding muscles and fat. As such, the production of offloading pressure ulcer prevention cushions requires the user to move around multiple times to evaluate and measure their physical deformities, which causes significant fatigue for the user and is a considerably cumbersome task for the technicians making the product. Due to this repetitive process, it takes about 4 to 5 days to produce an offloading cushion for a single user, and therefore the user must visit the production site for at least 2 days. The technology forming the background of the present invention is disclosed in Korean Registered Patent Publication No. 10-2106279. FIG. 1 is a schematic three-dimensional view for explaining the lower plate and seat plate of a pressure ulcer prevention cushion according to one embodiment of the present invention.
