PROBLEM TO BE SOLVED: To suppress action of a buoyancy onto an adhesive part during bathing when a bathing protecting tool of a peritoneal dialysis patient takes a bath.SOLUTION: A bathing protective tool 1 includes: a tubular cylindrical portion 2 with a closed distal end into which a catheter is inserted an annular sheet portion 3 connected with an opening edge of the cylindrical portion 2 a first adhesive layer 4 annularly provided on the end face of a sheet portion 3 and a second adhesive agent layer 5 provided on the distal end part of a cylindrical portion 2. The cylindrical portion 2 is folded at the initial condition, and when the cylindrical portion 2 is extended to store approximately whole the outside extending portion of the catheter into a cylindrical portion 2. Thereafter, the first adhesive layer 4 is stuck so that a stomach part being a part of a catheter to be taken out is surrounded, and in addition, the second adhesive agent layer 5 is stuck on a neck and a shoulder so that the cylindrical portion 2 is taken up.COPYRIGHT: (C)2014,JPO&INPIT【課題】腹膜透析患者の入浴保護具において、入浴時に浮力が接着部に作用することを抑制する。【解決手段】入浴保護具1は、カテーテルが挿入される、先端が閉塞される円管状の筒状部2と、筒状部2の開口縁に接合される環状のシート部3と、シート部3の端面に環状に設けられた第1接着剤層4と、筒状部2の先端部に設けられた第2接着剤層5と、を備える。そして、筒状部2は初期状態で折り畳まれていて、筒状部2を伸ばして筒状部2内にカテーテルの体外延出部分のほぼすべてを収容させる。その後、第1接着剤層4をカテーテルの取り出し部分である腹部を囲むように接着させ、更に、筒状部2を上に持ち上げるようにして、第2接着剤層5を首や肩などに接着させる。【選択図】図1
