Is provided. In this case, the covering cloth can be easily provided by sticking one side thereof to the adhesive layer (3) on the side edge of the covering film.

The covering cloth is made of a flexible nonwoven fabric or a plastic film such as polyethylene or polypropylene. When both sides are provided, they may be formed of the same or different materials such as a nonwoven fabric and a plastic film. The size of the covering can be appropriately selected depending on the treatment site and the like together with the covering material main body. In addition, the covering cloth can be made air-permeable, air-impermeable, liquid-impermeable, or the like as necessary.

〔Example〕

 Embodiments will be described with reference to the drawings.

1 and 2, a polyurethane film (2) having the same size as a polyester film (1) having a length of 700 mm × 320 mm × thickness of 38 μ and having a microscopic micropore having a thickness of 25 μ is superimposed, and an acrylic resin is applied to the surface of the polyurethane film. A pressure-sensitive adhesive layer (3) is formed to a thickness of 30μ, and a release paper (4) having a width of 260 mm is stuck thereon, leaving an exposed layer (3a) of about 30 mm of adhesive on both side edges (8). To form a covering material body (5), and to this exposed layer, a flexible nonwoven covering cloth (6) having a length of 700 mm and a width of 500 mm is adhered through an edge thereof, and a central portion of the covering material body is formed. Shows a skin covering material for operation having an opening (7) with a long diameter of 150 mm and a short diameter of 100 mm, and having a slit (cut line) (4a) in the release paper. This coating material is effective for, for example, inserting a puncture needle during epidural anesthesia, injecting a drug solution, and blocking nerves, and is disposable. Further, it can be formed in the same or different dimensions and used in a surgical operation other than the above anesthesia.

In the above description, the nonwoven fabric covering is provided on both side edges, but a polyethylene film may be used instead of the nonwoven fabric, or the nonwoven fabric may be provided on one side edge, and a plastic film such as polyethylene may be provided on the other side edge. Can be used as well.

In FIG. 3, a covering material extending outward is provided on one side edge (8) of one opposite side edge of the coating material main body (1), which is configured substantially similarly to FIGS. Are shown. This covering material can be used in substantially the same manner as that shown in FIGS.

These skin covering materials for treatment are put in a bag for sterilization or the like, and are subjected to gas sterilization or the like, and are supplied to the market. It is preferable that the above bag has good transparency.

[Action]

In order to use the skin covering material for treatment of the present invention, if the release paper has a slit, a part of the release paper is peeled off to expose a part of the adhesive layer, and when only one side has a covering cloth, the covering cloth is used. Is placed on the side of the physician who is to be treated, and if it is on both sides, either one of them is placed on the physician, for example, so that the nonwoven fabric is on the physician's side. Part or incision, etc.), and the covering material covers the surrounding undisinfected material (for example, a material to which germs such as clothes, futons, sheets, etc. are attached). Then, a part of the coating material main body is adhered via the above-mentioned exposed pressure-sensitive adhesive layer, and then the remaining release paper is peeled off and the entire coating material main body is adhered.
