Wheelchair cushion modification: device for locating high-pressure regions.
Location and geometry of bony prominences must be known in order to modify foam wheelchair cushions to reduce high seating pressures beneath patients susceptible to decubitus ulcers. A portable, adjustable "wheelchair barograph" has been built that will identify high pressure regions clinically by means of light patterns. No electronic readout is required to obtain accurate records of high pressure regions on the seating surface which may be added to the patient's record or used directly to mark locations for cushion modification.
