PROBLEM TO BE SOLVED: To solve the problem in which in the one called a human body site waterproof cover for a disease and a diseased part used for shower bath and washing in clear water that has been offered so far, the one in which the simple mounting and demounting by one hand are possible is extremely few, the helps of a caregiver and a nurse or the like are needed at many times, and the cover becomes the factors of the health professions burden and the medical treatment cost rise.SOLUTION: In the waterproof cover, to the circumference of a ring elastic body 1 that installs a circumferential groove 2 by a material with a low hardness to easily perform detaching, a cylindrical waterproof cover 6 or 7 of a waterproof material in which both ends or one end opens and that can be easily obtained is inserted, and fitted in the position of the circumferential groove 2 of the cylindrical waterproof cover with a rubber band 3, or the ring elastic body 1 and the cylindrical waterproof cover 6 or 7 are integrally bonded, thereby the softness and contractility of the ring elastic body is be made the best use, and the maintenance of a certain waterproof property can be achieved. Since the weight of an individual part is light and inexpensive, the help is also unnecessary, the detaching by self is possible. Moreover, since an economic burden is few, the waterproof cover is extremely effective for an inpatient.COPYRIGHT: (C)2013,JPO&INPIT【課題】 従来提供されてきたシャワー入浴や水洗の際に使用する疾病患部用の人体部位防水カバーと称されるものは、片手で簡易に装着、脱去する事ができるものが極めて少なく、介護者、看護師等の介助が必要となる事が多く、医療従事者の負担や医療コスト上昇の要因にもなっていた。【解決手段】 本発明の防水カバーは、上記課題を解決するために、脱着が容易に行えるように硬さの低い材料で周溝2を設けた円環弾性体1の外周に、安易に入手できる両端又は片端開口の防水素材の筒状防水カバー6または7を挿嵌し、筒状防水カバーの周溝2の位置に輪ゴム3で嵌着した、又は円環弾性体1と筒状防水カバー6又は7を接着して一体に構成したものである事により、円環弾性体の軟らかさと収縮性を生かし、確実な防水性の維持が実現できる。また個々の部品の重量も軽く安価なため、介助も不要で本人自身での脱着が可能になるばかりでなく経済的負担も少ないので、入院患者には極めて有効である。【選択図】図6
