Abstract: A connection assembly includes a connector and a coupler. The connector has a housing member, which is provided on an end with a plurality of air inlet pipes, one of which is a blocked pipe while all other ones are open pipes, and on another end with an air outlet pipe connected to an inflatable member. The coupler has a chamber internally defining a receiving space for holding the housing member therein and having a fixing end with a plurality of coupling pipes spaced thereon to connect with an air supply device. The air inlet pipes are inserted in the coupling pipes. An external detection system detects the internal pressure of respective coupling pipes to obtain a relative position of the blocked air inlet pipe on the connector, and accordingly regulates the air supplied by the air supply device to control the internal pressure of the inflatable member.

Abstract: A sensing device is configured for placing in an air cushion bed below air bladders thereof to detect an exact state of the bed in use, and includes a first and a second sheet connected together to define an air chamber therebetween. The air bladders and the air chamber are communicable with one another via inflation valves on the first sheet and are synchronously and identically inflated. First and second sensing elements are disposed outside and inside the air chamber, respectively. The first sensing element has deformation and acceleration sensors arranged thereon for monitoring how the bed reacts to a patient lying thereon and the manner in which the bed is being used. The second sensing element includes upper and lower conductive sensing sheets and an electrical connection state therebetween is used to detect whether the air bladders are sufficiently inflated. Thus, the air cushion bed is safer for use.

Abstract: An inflatable wrap with automatic tightness detection includes a wrap strap 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 and a sensor element arranged at locations separately corresponding to the two mating connection elements, and a processor element 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.

Abstract: A weight measuring system for hospital bed includes a bed bottom frame having two load cell mounting spaces formed at a front end and a rear end of the bed bottom frame between a first and a second supporting frame thereof; and a plurality of load cells mounted on the bed bottom frame to locate in the two load cell mounting spaces. Each load cell includes a supporting unit and at least one strain measurement unit attached to a lateral surface of the supporting unit for measuring an extent of strain elongation of the supporting unit under a bedridden patient's weight. With these arrangements, a nurse can not only measure a bedridden patient's weight without the need of moving the patient, but also monitor the patient's movement on the hospital bed in real time, preventing the patient from getting out of bed alone or carelessly falling off the hospital bed.

Abstract: A hospital bed with bed leaving alarm function includes a bed frame unit, a plurality of support pads mounted on the bed frame unit to together form a bed surface, on which a patient lies, sits or leans; and a plurality of casters. At least one bed leaving sensing unit is provided on a middle section of the bed surface and connected to an external monitoring device. Each bed leaving sensing unit includes a substrate for correspondingly locking to a top of the support pads, and a plurality of sensors spaced on the substrate and electrically connected to the monitoring device. The bed leaving sensing unit provides pressure data to the monitoring device, and the monitoring device emits an alarm when the pressure data indicates the patient is not lying on the bed, so as to prevent the patient from leaving bed alone or carelessly falling off the hospital bed.

Abstract: 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.

Abstract: A power-operated caster brake mechanism includes a driving device having a driving motor; a linking mechanism having a shifting member connected to a moving bar of the driving motor, and two rotating members connected to two ends of the shifting member; a caster connected to each rotating member and including a wheel and a brake and direction-lock mechanism, the latter including a brake block located in a wheel support, and a pin connected at an end to the brake block and another end to the rotating member; and a mechanical switch connected to the moving bar. When the driving motor shifts the shifting member, the rotating members rotate the brake blocks to different positions, bringing the casters to a braked, a direction-locked, or a freely swiveling state. In case the driving motor is failed, the casters can still be set to a desired operating state with the mechanical switch.

Abstract: A cluster-type fluid-conducting pipe connecting device includes a base section; a retaining ring fitted to a front of the base section and turnable from a closed position to an open position; the retaining ring and the base section being correspondingly provided at a front end with fixing slots and connection slots, respectively, and a sideward locating slot being formed at a rear end of each fixing slot; a reset structure enabling the retaining ring to automatically return from the open position to the closed position; and a connector having a forward pipe engaging section for fluid-conducting pipes to connect thereto, and a rearward plug section for inserting into the base section and externally provided with stubs that slide into the connection and fixing slots while the retaining ring is in the open position and are locked in the locating slots while the retaining ring is in the closed position.
