Abstract: An inflatable air mattress device includes a cover internally defining a first and a second receiving zone for receiving a pump and an air mattress therein, respectively. The air mattress includes a plurality of parallelly arranged air cells, each of which internally includes a first air chamber located below a second air chamber and having an elastic member provided therein. The pump is held in the first receiving zone via a movement-limiting mechanism and is provided with an air input and an air release line for communicably connecting to each of the air cells. Since the air cells, the pump and the air input and release lines all are arranged inside the cover, the inflatable air mattress device has an esthetic appearance and occupies less space. The elastic members in the first air chambers prevent a user from contacting with a hard bed frame when the air cells are deflated.

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.
