Description

The present invention relates to an affected area protective device.

Conventionally, adhesive plasters have been used to protect affected areas such as wounds. For example, "a non-water-permeable base material having a pressure-sensitive adhesive layer formed on one side and affixed to the pressure-sensitive adhesive layer side of the base material". It is made of a synthetic resin scratch protection material, and the scratch protection material has a smooth surface on one side in contact with the scratch and a liquid-proof layer on the other side to prevent the exudate from the scratch from permeating, and the inside is from the scratch. It is a porous absorption layer that absorbs the exudate, and ventilation holes are formed only in the place where the scratch protection material is attached to the base material, and the liquid-proof layer side of the scratch protection material is the base material. A sticking plaster characterized by being adhered to the pressure-sensitive adhesive layer ”has been proposed (Patent Document 1).

Japanese Unexamined Patent Publication No. 6-78948

The bandage is excellent in that it covers the wound and absorbs exudate to prevent water from entering the wound from the outside.

However, if the affected area such as a wound is near a part with active movement such as a joint, the wound may open or hit something due to unconscious movement, and it may take time to heal. Bandages cannot deal with such problems. Also, protecting the scab after a wound cannot be dealt with.

In addition, as a recent treatment method for wounds, there is a method called moist healing, which is a method of not making a scab, and the wound can be healed quickly. This is to repair the wound by preventing the wound from drying out so that the scab itself cannot be formed. Since the scab is formed by the exudate coming out of the wound coming into contact with air and drying, it can be suppressed by taking a method of not drying it. However, for example, in the case of a wound formed on a joint, if the wound is forcibly stretched, these effects cannot be expected.

The present invention is intended to solve the above problems, and an object of the present invention is to provide an affected area protective device for more appropriately protecting the affected area.

In order to solve the above problems, the affected area protective device according to one aspect of the present invention is an affected area protective device including a base material layer, an adhesive layer, and a release material layer, and includes a first sticking portion and a first sticking portion. By including a second sticking portion and an affected portion protection portion, an elastic material layer is included between the base material layer and the pressure-sensitive adhesive layer, and the elastic material layer in the affected portion protection portion has a restoring force. , Protect the affected area.

Then, when trying to change the distance between the first sticking part and the second sticking part, in other words, when trying to move the part near the affected part, it gives a force to resist the restoring force of the elastic material layer 14g. Must be stretched. However, it is difficult to extend the unconscious movement because its power is weak. This suppresses unconscious movements. On the other hand, when it is necessary to move consciously, the force is large, and 14 g of the elastic material is given a force against the restoring force to extend and move. Then, when the conscious movement is stopped, the restoring force of the elastic material layer 14g returns to the original state and returns to the unconscious movement suppressing state.

The affected area protective device 1f can suppress the opening of the affected area by suppressing the unconscious movement.

Further, the manufacturing cost of the affected part protective device 1f can be reduced by simplifying the configuration.

Although the embodiments of the affected area protective device according to the present invention have been described above, these are merely examples of the embodiments of the present invention, and the present invention is not limited thereto. The present invention includes a combination of the above embodiments and various modifications.

For example, the affected area protective device in each of the above embodiments may be configured to be transparent. Further, the affected portion protection portion may have another shape as long as it has a shape protruding toward the base material layer side.

Although the example of protecting the wound has been described above, the affected area protective device is also useful for, for example, limiting the expansion and contraction of the joint of rheumatism and protecting the bruised affected area.
