Abstract

PROBLEM TO BE SOLVED: To press an injured surface with an injured surface protecting material. SOLUTION: This method is to press an injured surface using force when a water absorbing material 1-b swells up with water, for instance, a body fluid from the injured surface to expand the volume by covering the injured surface with an injured surface protecting material impregnated with a non-plant derived material which increases its volume through water or containing a non-plant derived a water absorbent polymer before swelling into a substrate 1-a.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flaw protecting material for protecting a flaw.

[0002]

2. Description of the Related Art Conventionally, there are gauze and bandage as wound surface protecting materials.

[0003]

Generally, when bodily fluid oozes from a wound, the wound is pressed. For example, a treatment in which gauze is applied to a wound in which body fluid is exuding and a bandage is strongly wound over the wound is an example. In this case, the strength of the bandage must be changed according to the amount of bodily fluid exuding from the wound. Techniques are needed to adjust the strength of the bandage so that the wound is not damaged. In particular, it is difficult to wrap a bandage while adjusting the strength in accordance with the condition of the wound, even in a region where the bandage is relatively easy to wrap, such as a thigh or an arm. further,
When the wound site such as the nose or ear is complicated, it becomes more difficult to compress the wound surface. For example, the ear is an example of a complex part. If you have a wound on your ear, you are currently using a large amount of gauze. That is, a large amount of gauze is crushed and fixed with a tape while pressing it against the ear. At this time, the gauze is using the force to return to the original state to press the wound. However, the treatment of the protective material takes a longer time on a wound surface such as an ear than on other parts. This is a major problem in medical practice where rapidity is required.

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and covers a part or all of a wound surface of a human body or an animal and protects the wound surface. In the material, a non-plant-derived material that increases the volume via water or a non-plant-derived polymer water-absorbing material and a base material that holds them before swelling, and the material and the water-absorbing material try to increase the volume An object of the present invention is to solve the above-described problem by using a wound surface protection material that compresses a wound surface using a force that sometimes occurs.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention comprises a substrate 1-a and a water-absorbing material 1-b as shown in FIG. When the volume of the water-absorbing material swells, the volume of the water-absorbing material tends to expand. In addition to the water absorbing material, a substance that increases the volume through water may be used. Changes that increase the volume include chemical changes and state changes. For example, an attempt is made to compress the wound surface with a force that causes the volume to expand when the water absorbing material swells.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is used, for example, as follows.
First, the protective material is applied to the wound surface, and the protective material is fixed to the wound surface by wrapping it over the bandage with a bandage. At this time, the force for pressing the wound surface is a force generated when the bandage is wound. At this point, suppose that bodily fluid oozes from the wound surface. The water absorbing material contained in the protective material absorbs body fluid and swells. At this time, the bandage prevents expansion of the volume. The resulting force compresses the wound surface. The greater the amount of bodily fluid from the wound, the more the water-absorbing material swells, and the stronger the pressure on the wound surface. If the base material has the ability to hold the water-absorbing material so that the water-absorbing material absorbs a certain amount of bodily fluids and the pressure on the wound surface increases, and the wound surface is not damaged, the wound surface May not be over-pressed. Further, the present invention can compress the wound surface by absorbing water, which is not body fluid, from the wound surface.

According to the present invention, it becomes possible to press the wound protected by the present invention according to the body fluid oozing out from the wound surface.

Claims (1)

[Claims] 1. A wound-protecting material that covers a part or the whole of a wound surface of a human body or an animal and protects the wound surface, wherein the material is not a plant-derived material that increases in volume through water or a plant-derived material before swelling. And a base material for holding the same, and the above-mentioned substances and the water-absorbing material use a force generated when increasing the volume to compress the wound surface.
