PROBLEM TO BE SOLVED: To provide a detection system for a toilet unit for use in a supine position which can detect water rising within the toilet unit for use in the supine position and control to forcibly discharge water and which can detect that buttocks of a patient have closely contacted the toilet unit for use in the supine position and control to make water supply from each nozzle impossible when the close contact cannot be detected.SOLUTION: In the detection system for the toilet unit A for use in the supine position, a treating body formed in a substantially Y-shape by a urination and defecation container as a lateral member and a washing nozzle retainer as a vertical member is formed in a boat shape, the washing nozzle retainer is held in the crotch of the patient to enable the patient to urinate and defecate within the urination and defecation container, an injection nozzle provided at a head section of the urination and defecation container is provided to be capable of crushing and conveying the stools, and a nozzle provided on the washing nozzle retainer is adapted to wash the private parts. A water level sensor is installed at a side edge section of the urination and defecation container on the upstream side to detect water rising due to wash water and water from the injection nozzle and control to forcibly discharge the urination and defecation out of the urination and defecation container when the water reaches a certain level.COPYRIGHT: (C)2009,JPO&INPIT【課題】人体仰臥用便器内の水位上昇を検知し強制的に排出するように制御し、人体仰臥用便器に患者の尻部が密着したことを検知し密着検知が不可のとき各ノズルからの送水が不能となるように制御する人体仰臥用便器の検知システムを提供すること。【解決手段】横部材の排尿便受け部と、縦部材の洗浄ノズル保持体とにより略L字形状に構成した処理部本体を舟型形状とし、患者の股間部に洗浄ノズル保持体を挟持して排尿便受け部内に排尿便を可能とすると共に排尿便受け部の頭部に設けた射水ノズルにより便の粉砕と搬送を可能とし、洗浄ノズル保持体に設けたノズルにより局部の洗浄を行うように構成し、排尿便受け部の上手側の側縁部に水位センサーを設置し、洗浄水及び射水ノズルからの水とによる水位上昇を検知して、一定の水位に達すると強制的に排尿便を排尿便受け部内から外方へ排出するように制御することを特徴とする。【選択図】図1
