PROBLEM TO BE SOLVED: To provide a bathing device and a bathing system which allow a bathing person to take a bath safely by preventing the back part of the head or the ears of the person from being soaked in hot water and also allow the person to be sufficiently soaked in the hot water up to the shoulders.SOLUTION: The bathing device includes a stretcher 4 having a backrest section 11 that can be inclined as a whole and a bathtub 3 having a receiving section 7 inside for receiving the stretcher 4. The bathing device allows a person to take a bath by elevating the bathtub 3 while the stretcher 4 is mounted on the receiving section 7. The backrest section 11 is divided into at least two or more parts, and each part is connected to another via a joint axis. With such a configuration, a person can take a bath while at least a mounting part of the backrest section 11 on which the head of the bathing person is mounted is moved and inclined to an inclination angle with respect to a horizontal line that is larger than the inclination angles of the other parts of the backrest section with respect to the horizontal line.COPYRIGHT: (C)2011,JPO&INPIT【課題】入浴者の後頭部や耳が湯に浸かることなく安全に入浴を行えるようにするとともに、肩まで湯に充分浸かることができる入浴装置及び入浴システムを提供すること。【解決手段】背もたれ部11全体を傾動可能にした担架4と、この担架4を受ける受け部7が内方に設けられる浴槽3と、を備え、受け部7上に担架4を載せた状態で浴槽3を上昇動作させて入浴を行う入浴装置であって、背もたれ部11を少なくとも二つ以上の部分に分割するとともに、各部分の間を関節軸を介して連結し、背もたれ部11上において少なくとも入浴者の頭部が載置される載置部分の水平線に対する傾斜角度を背もたれ部の他の部分の水平線に対する傾斜角度より増角して傾動させて入浴を行えるようにした。【選択図】図3
