PROBLEM TO BE SOLVED: To solve the problems such as infection to an operator or time load for the operation, and a trouble of an instrument due to opening and closing in the drainage disposal after phlegm suction in a hospital.SOLUTION: First, a fine suction tube is inserted from a suction port of a drainage storage bottle to suck the drainage into a drainage tank without opening a lid. After the end of suction, an antiseptic solution is automatically fed. After the end of sterilization, the antiseptic solution is drawn into the drainage tank by the first operation. Since the drainage tank, an antiseptic solution tank, a pump and an operating part are housed in one cart, the cart is moved intact to a sewage disposal chamber, a drainage hose is set, a stop valve (R) is opened, and the exhaust pressure of the pump is applied to the drainage tank to discharge the drainage.COPYRIGHT: (C)2014,JPO&INPIT【課題】病院での、痰吸引後の排液処理において、作業者への感染又作業の時間的負担、開閉する事による器具の不具合等の問題を解決する。【解決手段】まず排液貯留瓶の吸引口から細い吸引チューブを差し込み、蓋を開放することなく、汚水槽に排液を吸引する。吸引終了後、消毒液を自動で送る。消毒終了後最初の動作で汚水槽にこの消毒液を引き込む。汚水槽、消毒液槽、ポンプ、操作部は一つのカート内に収納されているのでそのまま、汚物処理室へ移動し排液用ホースをセットして、ストップバルブ(R)を開き,汚水槽にポンプの排気圧力をかけ排液する。【選択図】図1
