PROBLEM TO BE SOLVED: To provide an excretion detection system of non-contact type which is inexpensive, and capable of detecting any excretion from a care receiver, independent of adult or infant, without making him or her feel uncomfortable, and without imposing any burdens on his or her caregiver, or a child care person.SOLUTION: The excretion detection system includes a mattress 40 for a bed, on which a care receiver or infant is laid, including a plurality of gas paths 41 each having a plurality of holes 41a on the laid side a portable gas detecting means 44 sending a gas detection signal if detecting any excretion-generated gas sucked by suction pumps 42 proided at the end of each gas path 41 an gas output change detecting means determining whether there is any change in output gas volume based upon the gas detection signal and sending a gas output change detection signal if any an excretion detecting means determining that there is excretion when finding an increased amount of output gas based upon the gas output change detection signal a means for notifying of excretion determination to a caregiver and a recording means for recording at least any one of the results from the gas output change detection signal, excretion determination, and determination notification.COPYRIGHT: (C)2013,JPO&INPIT【課題】費用面に優れ、かつ、介護者又は育児者の負担がなく、さらに、被介護者又は乳幼児が不快になることがなく排泄検知できる非接触型の排泄検知システムを提供する。【解決手段】被介護者又は乳幼児が載置されるベッド用マットレス40は、載置される側に複数の孔41aを有する複数のガス経路41を形成して構成される。排泄物から発生するガスであって、各ガス経路41の端部に設けた吸引ポンプ42より吸引されたガスを検知してガス検知信号を出力する可搬型ガス検知手段44と、ガス検知信号に基づいてガスの出力の変化の有無を判定しガスの出力変化があった場合にガス出力変化検知信号を出力する手段と、ガス出力変化検知信号に基づいてガスの出力の変化が増加した場合に排泄があったと判定する手段と、排泄判定を報知する手段と、ガス出力変化検知信号の出力、又は、排泄判定、又は、報知手段による報知の少なくとも何れかを記録する手段を有する。【選択図】図6
