PROBLEM TO BE SOLVED: To provide a care bathtub into which a care-receiver can get by moving horizontally while he or she is seated on a bathing wheelchair 11 capable of decreasing a required amount of hot water and reducing a bathroom area, solving the problem that an amount of hot water required for bathing is currently large, and the problem that a large bathroom area is currently required since a wash place and a care bathtub installation place are separately provided.SOLUTION: When a bathtub is viewed planarly, a short side direction is expressed as transverse, and a long side direction is expressed as vertical. First, the long side direction is transversely cut into two upper and lower parts. The lower part is cut vertically. The upper part is expressed as a bathtub body 1, and two of the lower parts are expressed as bathtub doors 2. The bathtub doors 2 are connected to the bathtub body 1 by connection arms 7, and are opened/closed with a connection arm shaft 8 as an origin. Air bags 3 are incorporated in the bathtub doors 2, after the bathtub doors 2 are closed, the air bags 3 are inflated to seal a gap, and the care bathtub is completed.SELECTED DRAWING: Figure 1【課題】 入浴用車椅子11ごと水平移動で浴槽に入れる介護用浴槽において、現状では入浴に必要な湯量が多い。また、洗い場と介護用浴槽設置場所が別個な為、大きな浴室面積を必要とする。本発明の目的は、必要湯量を低減し浴室面積を小さくできる介護用浴槽を提供することにある。【解決手段】 浴槽を平面的に見て短辺方向を横、長辺方向を縦とする。まず長辺方向を横に切断し上下のパーツに2分割する。さらに下部のパーツを縦に切断する。上部のパーツを浴槽本体1とし、下部のパーツ2個を浴槽扉2とする。浴槽扉2は浴槽本体1と接続アーム7で接続し接続アーム軸8を起点に開閉させる。浴槽扉2には空気袋3を内包し浴槽扉2を閉鎖した後、空気袋3を膨らまし隙間を密閉することで介護用浴槽を完成させる。【選択図】図1
