PROBLEM TO BE SOLVED: To solve such a problem that a conventional bathtub requires a care-giver having a special body strength or special skills to give a care-receiver unable to take a bath by him/her-self a bath, regardless of its type, and a bathtub facilitating giving the care-receiver a bath and lifting the care-receiver from the bath is desired especially for home care.SOLUTION: A bathtub body has a peripheral wall, a part of the peripheral wall is provided with an opening/closing side wall horizontally opened to be parallel with a bathtub floor, the bathtub internally has a movable sliding floor surface fully drawn out on the opened opening/closing side wall, the care-receiver is positioned on the drawn sliding floor surface in an appropriate posture, the sliding floor surface is housed into the bathtub together with the care-giver, and then the opening/closing side wall is closed to a position forming the entire peripheral wall of the bathtub to form the complete bathtub, thus the care-giver is able to readily give the care-receiver a bath.COPYRIGHT: (C)2012,JPO&INPIT【課題】従来の浴槽においては、その形式に係わらず、自力での浴槽へ出入りが不可能な要介護者を、特別な体力、技量をもたない介助者が、要介護者を簡単に浴槽へ出入りさせられる浴槽がなく、特に在宅介護にあっては介助作業の深刻な課題となっている。【解決手段】浴槽本体の周壁の一部である開閉側壁を、浴槽床面と並行で水平になるよう開き、浴槽内の可動スライド床面を、開閉側壁上へ完全に引き出し、引き出したスライド床面上に要介護者を適切な姿勢で収容し、要介護者ごとスライド床面を浴槽内に収容した後に開閉側壁を、浴槽周壁を構成する位置まで閉じることにより完全な浴槽が構成され、介助者による要介護者の容易な入浴を可能とする。【選択図】図4
