Disclosed is detected to identify a person with a transmitter with an ID chip (the caregiver) and to provide a sensor that identifies the person to be notified to nurses and others. By A ID chip that incorporates a transmitter circuit and battery, transmits continuously or intermittently a weak radio signal, thereby carrying the transmitter 2 to the person (the nurses). The transmitter and the first receiver 4 for outputting an a detection signal approaches within a predetermined distance in the room or the like, a lifting sensor 3 disposed from said one receiver within a predetermined distance, the nurses on floor sensor There is placed a second receiver 5 for outputting a detection signal by receiving a contact signal upon contact. Wherein when the first receiver 4 and the second receiver 5 outputs a detection signal at the same time, it transmits a control signal including the ID information from the control section 6 to notify the caregiver by a broadcast or the like. .BACKGROUND 2【課題】IDチップ付きの送信器を持った人(被看護者)を識別して検知し、看護者等に報知する人を識別するセンサを提供する。【解決手段】送信回路と電池を組み込んだIDチップにより、微弱な無線信号を連続又は断続して発信する、送信器2を人(被看護者)に携帯させる。居室等に該送信器が所定距離以内に近づくと検知信号を出力する第一受信器4と、該第一受信器から所定距離以内に設置された離床センサ3と、該離床センサに被看護者が接触したときの接点信号を受信して検知信号を出力する第二受信器5を配置する。前記第一受信器4及び第二受信器5が同時に検知信号を出力したときに、ID情報を含む制御信号を制御部6から送信し報知器等で看護者に報知する。【選択図】図2
