Abstract: The present invention relates to a patient off-bed notification system, which includes a pressure-sensitive sensor pad, a signal converter, and a signal transmitter. The pressure-sensitive sensor pad includes an upper conductive layer, a bottom conductive layer, and an insulating layer arranged therebetween, where the upper conductive layer and the bottom conductive layer can generate an electrical signal due to a pressure change. The signal converter is used to receive the electrical signal from the pressure-sensitive sensor pad and perform operational analysis to produce a corresponding patient status signal. The signal transmitter transmits the patient status signal from the signal converter to a server, and the server displays or/and stores corresponding information according to the patient status signal. Thus, patient's statuses in bed can be known at any time, and the harm caused when the patient leaves the bed alone can be minimized, thus effectively improving the work efficiency of caregivers.

Abstract: A system for detecting wetness of article used by a care-receiver is provided, comprising: a radio frequency identity (RFID) tag to be attached onto an outer surface of an article used by the care-receiver, and a RFID reader. The RFID reader includes at least one first antenna module, a processor unit and a first wireless communication module. And the system further comprises a protective unit is configured for accommodating the RFID reader and buffering external pressure on the RFID reader to protect the RFID reader. The RFID reader is configured for being disposed on a back of a cushion. The first wireless communication module is configured to send a detection signal (excitation signal) through the first antenna module to the RFID tag and the processor unit determines the water content (%) of the article at the usage time (t) by using the RSSI(0) and RSSI(t).

Abstract: A state determination apparatus for a care-receiver is provided, comprising: a communication unit and a protective unit. The communication unit includes at least one first antenna module and a first wireless communication module. The protective unit is configured for accommodating the communication unit and buffering external pressure on the communication unit to protect the communication unit. The state determination apparatus is configured for being disposed on a back of a cushion. The first wireless communication module sends a detection signal through at least the first antenna module so as to communicate with a radio frequency identity (RFID) tag used by the care-receiver. After sending the detection signal, the communication unit determines whether a response signal from the RFID tag is received or information of the response signal is read so as to determine a state of the care-receiver.
