Description

  The present invention relates to a bandage to be applied to joints such as elbows, knees, shoulders, wrists, ankles, and fingers. As such adhesive bandages, pads are placed on adhesive bandages commonly used as films, which are used to fix gauze that protects wounds, and on the adhesive layer of a support that has an adhesive applied to one side. There is an adhesive bandage.

  Adhesive plaster is widely used as a method of first aid for unexpected wounds in daily life. In addition, various types and sizes of adhesive bandages are manufactured and sold so that they can accommodate various wound sizes, depths, and sites. These bandages are mass-produced due to high demand and are distributed in the market at a relatively low price. These bandages also have a background of simplification, efficiency, and ease of the manufacturing process, and many of them employ a rectangular shape or a shape with rounded corners.

  However, when applying adhesive bandages to joints such as elbows, knees, shoulders, wrists, ankles, and fingers, if the joints are moved after application, the movement of the joints cannot be handled, and the adhesive bandage may partially lift or peel off. Then, there was a problem that water and germs entered from the outside.

As countermeasures, various shapes of adhesive bandages have been proposed so far. For example, Japanese Utility Model Publication No. 55-12980 and Utility Model Publication No. 63-1995831 disclose adhesive bandages in which a protruding portion is provided on the adhesive layer surface in the width direction of the pad, but the basic shape is not changed. Therefore, the above problems could not be solved.
Japanese Utility Model Publication No. Hei 6-81517 discloses an adhesive bandage in which at least one pair of opposite sides forms an arc in the same direction. Discloses adhesive bandages that can respond to large movements at the site, but specializes in unidirectional movement, specializes in thin indirect areas such as fingers, and all movements of joint areas It was difficult to solve the problems so far.

The surface of the human body is bumpy and not a flat surface, but rather a curved surface. When it becomes a joint part, the curved surface is larger than the other parts. Furthermore, the human body can bend and stretch by freely moving its joints. In addition, when a person falls and is injured, a joint part such as an elbow or a knee is often the target.
The bandage sticks firmly to protect the wound from external factors such as water and bacteria in joint sites that are often injured. Must be designed to

The present invention has been developed in view of the above circumstances, and provides a bandage having the following characteristics.
That is, in a film-like adhesive bandage in which an adhesive is applied on one surface, or an adhesive bandage in which a pad is disposed on an adhesive layer of a support, two opposite sides of the adhesive bandage are curved inward.

  In the adhesive bandage of the present invention having the above-described configuration, since the two opposite sides of the adhesive bandage are curved inward, even if the joint part is moved after application, the movement of the joint part can be easily handled. Therefore, it is possible to effectively prevent the adhesive bandage from partially rising or peeling off, and as a result, it is possible to prevent water and bacteria from entering from the outside.

  A preferred embodiment of the bandage of the present invention will be specifically described with reference to the accompanying drawings.

  FIG. 1 is a schematic top view showing a bandage according to an embodiment of the present invention. The adhesive bandage of FIG. 1 is comprised by the pad 2 and the support body 1 which contact a wound. An adhesive for applying to the skin is applied to one surface of the support 1, and the pad 2 is disposed on the adhesive layer.

  As indicated by reference numeral 3 in FIG. 1, two opposite sides of the support 1 are curved inward toward the pad 2 side. In this way, by configuring the two opposite sides in a curved shape, even if the joint part is moved after application, it can easily cope with the movement of the joint part, and it is possible to effectively prevent the adhesive bandage from lifting and peeling off.

The support 1 is a base material for adhesive bandages, and is generally used with polyolefin resins such as polyethylene and polypropylene, polymer sheets such as polyvinyl chloride, polyurethane, polyamide, polyvinylidene chloride, ethylene, vinyl acetate, cloth, nonwoven fabric, etc. Can be configured.
In the present invention, the material of the support 1 is not limited to a specific material. However, the support 1 can be expanded and contracted according to the expansion and contraction of the joint part and the shape of the skin surface. What can hold | maintain the closely_contact | adhered state suitably is preferable. Moreover, in order to prevent the affected part from being stuffy, those having appropriate moisture permeability or water vapor permeability are preferable.

  As the pressure-sensitive adhesive to be applied to the support 1, commonly used natural rubber-based, synthetic rubber-based, acrylic, silicone-based pressure-sensitive adhesives can be used. In general, it is preferable to use an acrylic pressure-sensitive adhesive that is less irritating to the skin.

The pad 2 can be composed of absorbent cotton, polyethylene, nonwoven fabric, or the like. The thickness of the pad 2 is desirably 1 mm or more. If it is less than 1 mm, blood from the wound reaches the support 1 through the pad 2, and further, blood may adhere to clothes through the support 1. Moreover, when thickness is less than 1 mm, the relaxation effect with respect to the external irritation | stimulation to an affected part will become inadequate, and it may also become widening a wound.
Further, like the support 1, the pad 2 can be expanded and contracted in accordance with the expansion and contraction of the joint part and the shape of the skin surface, and is always kept in a state of being suitably adhered to the application part. Those are preferred. Since the pad 2 is in contact with the wound, if there is stretchability to follow the movement of the joint, the pressure applied to the wound is dispersed by moving the joint, and the burden on the wound can be reduced.

  The bandage shown in FIG. 1 is provided with a pad 2 on the adhesive layer of the support 1, but is generally used to fix a bandage (such as a gauze that protects a wound) without such a pad. The present invention can also be applied to an adhesive bandage called a film.

Such a bandage (film) is not shown, but its shape can be considered as a pad 2 omitted from FIG.
Even in such a bandage, the same effect as described above can be obtained by bending the two opposite sides of the bandage inward. In such adhesive bandages, the same adhesive as described above can be used as the adhesive layer.

It is the schematic of the adhesive bandage which concerns on one Embodiment of this invention.
