The invention relates to the technical field of monitoring equipment, in particular to an old people
sleep monitoring and
nursing device which comprises a
nursing mechanism and a
pressure sensor, and the
pressure sensor is installed on the
nursing mechanism and used for sensing physiological signs of a sleeper; the nursing mechanism comprises a bottom plate, a lifting plate, a transmission mechanism and an
air cushion; the lifting plate is fixedly connected with the end of the bottom plate, the lifting plate is connected with the
air cushion through the transmission mechanism, and the
air cushion is used for generating air pressure to enable the lifting plate to vertically ascend and descend. The transmission mechanism comprises a cylinder body, a sealing plate and a transmission unit; the
barrel is installed on the outer side wall of the side plate, the sealing plate is arranged in the
barrel in a sealed and sliding mode, and the top of the
barrel is connected with the air outlet end of the air
cushion. According to the device, through pure mechanical pneumatic transmission, when the risk of falling from the
bed is detected, no electronic
signal processing or
algorithm decision is needed, the air pressure change is directly converted into the vertical movement of the baffle, the response
hysteresis is fundamentally eliminated, and a
physical barrier can be instantly raised when the body of an old person is unbalanced or turns to the
bed edge.
