PROBLEM TO BE SOLVED: To preliminarily prevent such an accident as the falling of a hospitalized person, his falling from a bed and his leaving from a facility by early and surely discriminating the bed leaving of the hospitalized person from a bed or the like at night, and notifying a care staff of the result.SOLUTION: This bed leaving alarm device is configured of: an ultrasonic wave vibration detection sensor A fixed to a berth or bedding for detecting vibration generated by the living body activity of a person an air pressure detection sensor B installed in the berth or bedding for detecting an air pressure generated according as the weight of a person is added a control device E for inputting each detection signal from the ultrasonic vibration detection sensor A and the air pressure detection sensor B, and for outputting each detection signal to a data communication circuit H and an arithmetic controller F for inputting each detection signal from the control device E, and for issuing the alarm of the bed leaving operation of a hospitalized person or his preliminary operation for bed leaving when a detection signal from the ultrasonic wave vibration detection sensor A is increased, and a pressure detection signal from the air pressure detection sensor B is decreased.COPYRIGHT: (C)2009,JPO&INPIT【課題】 入院入所者等の夜間等におけるベッドなどからの離床を早期にしかも確実に判別し、これを介護者へ通報することにより、入院入所者の転倒やベッドからの転落、施設からの離脱等の事故を未然に防止する。【解決手段】 寝台や寝具に固定され、人の生体活動により生じた振動を検出する超音波振動検知センサAと、寝台や寝具に敷設され、人の体重が加わることにより生じた空気圧を検出する空気圧検知センサBと、前記超音波振動検知センサA及び空気圧検知センサBからの各検出信号が入力されると共に当該各検出信号をデータ通信回路Hへ出力する制御装置Eと、前記制御装置Eからの各検出信号が入力され、超音波振動検知センサAからの検出信号が増大すると共に前記空気圧検知センサBからの圧力検出信号が減少した時に、入院入所者の離床動作又は離床のための予備動作の警報を発する演算制御装置Fとから構成する。【選択図】 図1
