Description

[Detailed description of the invention] [Industrial field of application] The present invention is a medical adhesive dressing, such as a surgical drape, a trauma dressing, a bandage, etc., in which adhesive films become entangled with each other when used (applied). The present invention relates to the structure of an easy-to-handle medical adhesive dressing material that prevents mating.

[Prior art]

In the medical field, relatively thin, breathable films (such as polyurethane films) coated with an adhesive on one side are used for treating wounds and fixing catheters and the like on the skin. The film used for this is generally a thin film of 50 microns or less, and when the release paper that protects the adhesive is removed, the adhesive side becomes entangled with each other because the film is flexible.
It is extremely difficult to apply the adhesive neatly on the skin without causing wrinkles. For this reason, medical adhesive covering materials with various improvements have already been devised.

For example, in Japanese Utility Model Application Publication No. 62-87624, a release paper is attached to the adhesive layer of an adhesive film, and a mount is attached to the other side, and the adhesive force between the adhesive layer and the release paper is the same as that between the film and the mount. An adhesive sheet is disclosed in which the adhesive force is smaller than that of the adhesive sheet, and the release paper is first peeled off and the adhesive sheet is applied onto the skin, and then the backing paper is peeled off. In this case, the thin film is attached to the mount, so
Although the film does not wrinkle or the adhesive surfaces stick to each other, it is inconvenient as a medical dressing. In other words, when used to fix wounds on the human body or catheters, even though a thin, flexible and stretchable film is used, the stiffness of the mount reduces its flexibility, resulting in uneven wound areas. It is rather inconvenient to paste it on the etc.

Furthermore, in Japanese Utility Model Application Publication No. 62-42816, the above-mentioned mount is divided into a central part and an edge part, and the central part is first peeled off to leave the edge mount, and then the release paper is peeled off. A configuration is disclosed in which the edge mount is peeled off after application. A similar device was published in Japanese Patent Application Laid-open No. 47-
It is also disclosed in Publication No. 115480. However, with these dressings, after peeling off the release paper, the adhesive film is generally applied to the wound by pinching both parts with both hands and applying tension to the adhesive film.
At this time, hands inevitably come into contact with the exposed adhesive, which poses a risk of bacterial contamination. In addition, because the adhesive strength of the backing paper to the film is greater than that of the release paper, there are disadvantages such as the thin film tends to wrinkle when the center backing paper is peeled off and must be removed carefully. .

[Purpose of invention]

The present invention has been developed in view of the above-mentioned circumstances, and is capable of smoothly applying an adhesive film to the skin without causing wrinkles due to thin adhesive films getting entangled with each other. The purpose of the present invention is to provide a medical dressing that can be handled hygienically without directly touching the agent.

[Structure of the idea]

In order to achieve the above object, in the present invention, the entire surface of the adhesive film having the adhesive layer is covered with three release papers that are removable and adjacent in one direction, and the adjacent sides of each release paper are has a tab extending toward the release paper side facing each other, and on the other side of the adhesive film, three pieces of release paper are placed on each side of the edge of the film in a direction perpendicular to the adjacent side direction. It is made by attaching. Further, the tape-shaped reinforcing mount may be extended in the long side direction, folded back, and bonded or connected to a release paper.

Hereinafter, the medical adhesive according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing an example of the medical adhesive covering material according to the present invention, and FIG. 2 is a sectional view taken along line A-A' in FIG.

This medical adhesive dressing has a rectangular shape with a heat resistance of 50
An adhesive film 1 consisting of a transparent or translucent synthetic resin film 2 of micron size or less and an adhesive layer 3, three release papers 4a, 4b, 5 removably provided to the adhesive layer 3, and an adhesive film. Tape-shaped reinforcing mounts 8a, 8 provided on the other side of 1
It is composed of b.

The release papers 4a, 4b, and 5 are papers whose surface has been subjected to a release type treatment using paraffin, silicone oil, etc., and three pieces of release paper 4 adjacent to each other in one direction
a, 4b, and 5 are attached over the entire surface of the adhesive layer 3 to protect the adhesive. The pasting method is such that the pasting is done adjacent to the central part and both sides thereof in one direction, and on the adjacent sides, peeling tabs 7 are formed that extend toward the release paper side facing each other, and the adjacent tabs are pasted. 7 with release paper 4a, 4b at fold 6
It is folded up.

Further, on the other side of the adhesive film 1 (the side on which no adhesive is applied), tape-shaped reinforcing mounts 8a and 8b are placed on both sides of the adhesive film edge in the direction perpendicular to the folding direction adjacent to the release paper. It is attached in a removable manner, and may be attached to the film 2 thermally or with an adhesive.

When applying this medical adhesive covering material to the skin surface, first, the release paper 5 at the center is peeled off to expose the adhesive layer 3 at the center of the adhesive film 1. In this state, the four sides of the adhesive film 1 are lined with release paper 4a and 4
b, and tape-shaped reinforcing sheets 8a and 8b, which has the advantage that even if the film 2 is ultra-thin with a thickness of 50 microns or less, the film will not roll up and become entangled. In addition, the release papers 4a and 4b are held with both hands and pasted on the skin surface of the affected area.At this time, the central part of the adhesive film allows the position of the affected area to be observed and confirmed through the film, and the position is accurately aligned and pasted. There are advantages that can be achieved. After pasting it on the affected area, the release papers 4a and 4b are peeled off and the whole adhesive film 1 is pasted on the skin surface, and then the tape-shaped reinforcing mount 8 is pasted.
When a and 8b are peeled off, the medical adhesive covering material can be applied beautifully without wrinkles. In particular, it is possible to provide a medical adhesive covering material that is easy to handle when applied over a catheter inserted into an affected area.

3 and 4 show another embodiment of the medical adhesive covering material according to the present invention, in which tape-shaped reinforcing mounts 9a and 9b are extended in the long side direction and folded back, and a folded portion 10 is formed. This differs from the example shown in FIG. 1 in that the terminals are glued or connected to release papers 4a and 4b. In the case of Fig. 3, when the release papers 4a and 4b are peeled off after being pasted on the skin surface of the affected area as described above, since the tape-like reinforcing mounts 9a and 9b are connected, the two are continuously attached together. It has the advantage of providing a medical adhesive dressing that is removable and extremely convenient for medical personnel.

[Effect of idea]

The adhesive covering material of this invention with the above structure is first peeled off from the center of the three release papers to expose the adhesive layer in the center, and then the remaining release papers and reinforcing paper on both sides are removed by hand. Holding the wound, the adhesive film is applied to the wound, etc., which eliminates the problem of the thin adhesive films intertwining with each other and causing irritation when rubbed.Next, peel off the release paper on both sides and apply the adhesive film. By peeling off the tape-shaped reinforcing backing paper, it is an adhesive coating that does not cause wrinkles during application and does not cause failures in application, and the folded part of the reinforcing backing paper is bonded or connected to the release paper. In this case, after pasting, the reinforcing mount can be removed at the same time as the release paper is peeled off, so that the pasting work can be carried out efficiently.
