【発明の詳細な説明】
［産業上の利用分野］
本発明は、切開手術を行う際にその切口に細菌
などが侵入しないように保護するカバーに関する
ものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a cover that protects the incision from invading bacteria during incisional surgery.
［従来の技術］
例えば開腹手術を行う場合、手術野及びその周
辺の皮膚を消毒し該切開部の周囲をカバーした後
にメスが入れられる。[Prior Art] For example, when performing open surgery, a scalpel is inserted after the surgical field and the surrounding skin are disinfected and the area around the incision is covered.
然し、皮膚表面を消毒しても、汗線が皮脂線の
奥まで完全に滅菌することは困難である。この
為、時間が経過すると、常在菌が移行して切口に
付着する虞れがある。 However, even if the skin surface is disinfected, it is difficult to completely sterilize the sweat glands to the depths of the sebaceous glands. Therefore, over time, there is a risk that resident bacteria may migrate and adhere to the cut.
こうした不具合を解消するため、従来において
は第８図に示すように切開予定部の外殻構造１
（皮膚、皮下脂肪、腹脂、腹膜）の上に、粘着剤
２ｂを介してして柔軟なフイルム２ａ（例えばウ
レタンフイルム）が粘着される。そして、メス３
によつて上記フイルム２ａを一緒に切開すると、
第９図に示す状態となり、皮膚表面から汗と共に
常在菌が排出されて切口１ａに侵入することが防
止される。 In order to eliminate these problems, conventionally, as shown in FIG.
A flexible film 2a (for example, urethane film) is adhered onto (skin, subcutaneous fat, abdominal fat, peritoneum) via an adhesive 2b. And female 3
When the film 2a is cut together by
The state shown in FIG. 9 is reached, and resident bacteria are expelled from the skin surface along with sweat and are prevented from entering the incision 1a.
［発明が解決しようとする問題点］
ところが、腹腔内には各種の常在菌が生息して
いるので、この常在菌が切口１ａに侵入する虞れ
が有る。また、空中を浮遊している常在菌が切口
１ａに侵入しないという保証も無い。[Problems to be Solved by the Invention] However, since various types of resident bacteria inhabit the abdominal cavity, there is a possibility that these resident bacteria may invade the incision 1a. Furthermore, there is no guarantee that resident bacteria floating in the air will not invade the cut 1a.
本発明は、切開部の切口を直ちに覆つて常在菌
の侵入を防止することが出来、しかも迅速・容易
に装着、離脱し得る切開部カバーを提供しようと
するものである。 SUMMARY OF THE INVENTION The present invention provides an incision cover that can immediately cover the cut end of an incision to prevent the invasion of resident bacteria, and can be quickly and easily attached and removed.

シートを介して接続したものである。上記の流体
として空気や水を用いると便利であるが、必ずし
もこれに限らない。[Means for Solving the Problems] In order to achieve the above object, the incision cover of the present invention comprises a pair of hollow annular members made of a flexible, water-impermeable sheet, and a pair of hollow annular members. The inner periphery of the pair of hollow annular members is provided with a means for inflating the member by supplying a fluid or deflating the member by extracting the fluid, and in a state in which the pair of hollow annular members are arranged one on top of the other, the inner circumference of the pair of hollow annular members is The parts are connected via a flexible, water-impermeable sheet. Although it is convenient to use air or water as the above-mentioned fluid, it is not necessarily limited to this.
［作 用］
上記のように構成されたカバーは、中空環状部
材に流体（例えば空気）を吹きこむと、例えば浮
輪のように立体的に形を整えて膨らみ、流体を抜
くと萎んで自在に形を変えることが出来る。[Function] When fluid (e.g., air) is blown into the hollow annular member, the cover configured as described above inflates into a three-dimensional shape like a floating ring, and when the fluid is removed, it deflates and freely moves. It can change shape.
このため、流体を抜いた１対の中空環状部材の
