Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a medical or surgical adhesive film dressing. More particularly, it relates to a wound dressing and a thin and transparent adhesive film dressing used for fixing an intravenous catheter (IV catheter).

[0002]

2. Description of the Related Art Thin and transparent adhesive film dressings are widely used in medical and surgical treatments and are provided to doctors in various sizes and shapes. An adhesive film dressing of about 10 cm square is useful for fixing the IV catheter, and an adhesive film dressing larger than the above size is also used as a drape for surgical incision. When it is used for fixing an IV catheter, it is necessary to observe the catheter insertion portion, and thus transparency of the adhesive film dressing is required. In addition, the adhesive film dressing is effective in preventing invasion of bacteria and infection. Further, as the adhesive film dressing, one having excellent water vapor permeability is useful so that the breathing of the covered skin can be prevented and the skin whitening phenomenon can be suppressed.

The prior art has provided various methods of handling adhesive film dressings. For example,

14 and Japanese Utility Model Laid-Open No. 62-42816, the adhesive film dressing is adhered by removing the release liner temporarily attached to the adhesive surface and removing the peripheral portion of the adhesive film dressing. Is held. In this case, because the finger touches the adhesive surface of the adhesive film dressing, the adhesive surface is soiled by the finger, and floating occurs in this part after sticking, because bacteria etc. of the operator's finger adhere to the adhesive surface. There were problems such as not being hygienic. In addition, this adhesive film dressing has a problem that it is difficult to apply the adhesive film dressing while holding the peripheral edge portion and pulling it even when desired, due to the regulation of the peripheral edge portion (it is not preferable to touch the adhesive surface with fingers). In addition, in order to prevent the adhesive surface from being soiled by fingers, some adhesive film dressings do not have an adhesive provided on the peripheral portion, but in this case, the peripheral portion is the adherend surface (skin, etc.).
Since it is not adhered to, there is a problem that it is easy to peel off from this portion after attachment.

Accordingly, it is an object of the present invention to provide an adhesive film dressing having improved handling properties and to provide an adhesive film dressing which can be applied to a patient without touching the adhesive surface of the adhesive film dressing. It is in.

For example, polymers such as acrylic polymers, polyethylene, ethylene-vinyl acetate copolymers, polyurethanes, polyether polyesters and nylon derivatives are used. Among these, polymers such as acrylic polymers, polyurethanes, polyether polyesters and nylon derivatives are
Since it is excellent in water vapor permeability when formed into a film, it does not interfere with the breathing of the covered skin and it can suppress the skin whitening phenomenon, and because it has transparency, it is applied on the place of application. It is particularly preferable because it can be attached while watching, and the catheter insertion part can be observed in the case of fixing the IV catheter.

The thickness of the film is preferably such that it can conform to the skin, and is usually 20 to 150 μm, preferably 25 to 75 μm.

Examples of the pressure-sensitive adhesive used in the present invention include various pressure-sensitive adhesives such as natural rubber-based, synthetic rubber-based, acrylic-based and silicone-based pressure-sensitive adhesives. In addition, an acrylic pressure-sensitive adhesive is preferably used because of the transparency of the film and the irritating effect on the skin.

Means for providing such a pressure-sensitive adhesive layer on the film include, for example, a method of applying the adhesive composition on the film, and a film made of a preformed adhesive composition on the film. Examples of the method for providing the layer include the method of providing the layer and the like, and these are performed by a known means. The pressure-sensitive adhesive layer has a thickness of usually 10 to 60 μm, preferably 20 to
It may be about 50 μm.

Examples of materials for the release liner provided on the pressure-sensitive adhesive layer include plastic films (eg, polyethylene, polypropylene, polyester, and laminated composites thereof), paper (eg, high quality paper, kraft paper, etc.) and the like. Among them, paper (eg, high-quality paper, kraft paper, etc.) and the like are preferable. Further, a release liner can be obtained by subjecting the surface of these to a silicone resin treatment, a fluororesin treatment, or the like. The thickness of this release liner is usually 50 to 250 μm, preferably 75 to 200 μm.
It may be about m.

Examples of the material for the releasable backing layer include plastic films (eg polyethylene, polypropylene, polyester, and laminated composites thereof), paper (eg high-quality paper, kraft paper, etc.), and preferably paper. (For example, high-quality paper, kraft paper, etc.). Also, a releasable backing layer can be obtained by subjecting the surface of these to a resin treatment such as polyester or polyolefin. The thickness of this peelable backing layer is usually 15 to 200 μm, preferably about 20 to 100 μm.

The peelable backing layer is provided to prevent the film or the like from being scratched or damaged before the adhesive film dressing is used, and the adhesive film dressing is sterilized. This is for keeping the film surface and the like in a sterile state for a long time in many cases.

In the present invention, the film (polymer film) is first extruded or otherwise formed on the peelable backing layer. Then, a pressure-sensitive adhesive layer is provided on the release liner by a known method,
The pressure sensitive adhesive layer side of this is attached to the film provided on the peelable backing layer. Next, the release liner is provided with a peripheral score line for peeling the central part thereof to form an exposed portion of the adhesive, and inside the score line, a film, a pressure-sensitive adhesive layer, a peelable backing layer and a release liner. The adhesive film dressing of the present invention can be obtained by providing a perforation line formed by passing through.

The score line for forming the adhesive exposed portion provided on the release liner is provided inside the adhesive film dressing in the shape of a frame parallel to the outer side of the adhesive film dressing, or It is provided in the shape of a frame having irregularities. Further, it is preferable that the cut line is a curved line or a straight line.
