PROBLEM TO BE SOLVED: To provide a detection device which can be used for both of a separation detection from a bed and a separation detection from a wheelchair so that a malfunction based on an individual difference of a cared person can be reduced.SOLUTION: A device performs a separation detection by means of a detector having a structure in which a soft material having an electric resistance falling within a range of from several Ω to several mega Ω is clamped by two electrodes, and having shape in which at least one of the electrodes has a projecting part directing toward the soft material having the electric resistance. Further, detection of both positive and negative voltage variations in a voltage drop between both of the electrodes of the pressure sensor is enabled by detection by means of an electronic circuit in the same device or by means of a program in a device using a microcomputer, whereby by generating an alarm, the device can have both of getting-out-of-bed detecting and standing-up-from-wheelchair detecting functions.COPYRIGHT: (C)2013,JPO&INPIT【課題】ベッドと車椅子からの離隔検知を共用化でき、被介護者の個人差に基づく誤動作が低減可能な検知装置を提供する。【解決手段】数Ωから数MΩの範囲の電気抵抗を有する柔軟素材を2枚の電極で挟み込んだ構造を有し,すくなくも一方の電極が電気抵抗を有する柔軟素材に向かって突起部yをもった形状を有する検出器により離隔検知を行う。さらに,その圧力センサの両極間の電圧降下の正負両方の電圧変化を同一装置の電子回路で検出することにより,またはマイクロコンピュータを用いた装置のプログラムにより検出することを可能にして,警報を発することにより離床検知と車椅子からの立ち上がり検知機能を兼用することを可能にする。【選択図】図1
