摘要:
An air cushion bed includes an inflatable air mattress; a first sensing mat provided on an outer surface of the air mattress and including a first upper and a first lower sensing sheet with a first soft pad sandwiched between them; and a first determining module electrically connected to the first upper and lower sensing sheets. When the first sensing mat is compressed and the first upper and lower sensing sheets are electrically connected to each other via holes on the first soft pad, the first determining module determines there is a patient lying on the air mattress or the air mattress with a patient lying thereon is insufficiently inflated. A second sensing mat and a second determining module can be additionally provided on another outer surface of the air mattress opposite to the first sensing mat for the air cushion bed to determine both of the above two situations.
摘要:
An inflatable wrap with automatic tightness detection includes a wrap strap (10) having at least one inflatable sealed zone formed thereon, at least one fluid guiding tube connected to between the sealed zone and an external fluid supply, at least two mating connection elements separately provided on two longitudinally opposite ends of the wrap strap, and a sensor module embedded in the wrap strap. The sensor module includes an output element (51) and a sensor element (52) arranged at locations separately corresponding to the two mating connection elements, and a processor element (53) electrically connected to the sensor element. When the two mating connection elements are detachably connected together to bind the wrap strap around a user's body area with the sensor element and the output element becoming aligned with each other to provide an alignment sensing function, it means the wrap strap forms a closed loop structure to provide a proper pressing force.
