ABSTRACT:
A monitoring system for monitoring inflation pressure within an inflatable cushion. The monitoring system includes a housing, a pneumatic tube, a locking adaptor and a sensing and signaling system. The pneumatic tube extends through the housing with the locking adaptor attached to the distal end of the pneumatic tube. The locking adaptor is effective for releasably and sealingly attaching the pneumatic tube to a stem valve on an inflatable cushion. The sensing and signaling is retained within the housing and includes at least a pressure sensor in pneumatic communication with the pneumatic tube proximate a proximal end of the pneumatic tube, and a means in communication with the pressure sensor for generating a perceptible signal when the pressure sensed by the pressure sensor falls below a predetermined threshold value.
