Description

[Detailed description of the invention] This invention relates to a cutting tool used by a judo therapist to fix an injured part when treating a fracture or sprain.

Traditionally, wood chips have been generally used as this type of cutting tool, but wood chips do not have the adaptability and adhesion to complex shapes such as human hands and feet, and are not always sufficiently effective as fixed cutting tools. Moreover, it is quite heavy and bulky, which results in an unreasonable burden on the patient, and it also has disadvantages such as being unsightly.

Therefore, comparatively thin and lightweight splints such as wire mesh formed into a predetermined shape and reinforced with mesh wire, sag-like splints, or cardboard are also used, but splints made entirely of mesh can cause injury. Although it has good adaptability to the site, it is not easy to mold and process, and because it is flexible in the lateral direction, it must be wrapped very tightly around the injured area with a silk belt, etc. There is a risk that excessive pressure may be applied, which may impair blood circulation.Furthermore, cardboard is unsightly and requires improvements in terms of water resistance and breathability, as well as reinforcement for hardness and durability.

In order to solve the above-mentioned conventional problems, this device is lightweight and easy to use without being bulky, is strong and durable, and maintains appropriate elasticity to prevent excessive pressure on the injured area. The purpose of the present invention is to propose a new cutting tool that can be easily and inexpensively manufactured into a shape that corresponds to the injured area, and has good air permeability.

An example of this invention shown in the drawings will be explained below.
The cutting tool 1 is mainly formed of a composite plastic plate made of glass fiber cloth covered with hard plastic, or other elongated plate of tough and moderately hard hard plastic, and the middle part 1a in the width direction is shaped so as not to be easily bent. It is formed to have a thick wall, and both side portions 1b are formed to have a thin wall that maintains elasticity so that it can be appropriately bent.

The cutting tool 1 is formed so that the cross section cut in the width direction forms an arc so that it can be placed in close contact with the injured part of the arm or leg. The shape and dimensions are determined depending on the body shape of the injured area, and preferably different sizes are pre-formed for adults and children, obese and thin.

Further, the cutting tool 1 is provided with ventilation holes 2 at predetermined locations.

When using the cutting tool 1 configured as described above for the treatment of fractures, sprains, etc., the injured area is treated and reduced, and a bandage is applied to the affected area (fracture or sprained area) and the entire surrounding area, and then The cutting tool 1 is applied to a position suitable for fixing the injured part so as to surround this part, and the cutting tool 1 is wrapped and fixed with a silk band or the like so that it does not come into direct contact with the skin.

In this case, since both sides of the cutting tool 1 are thin and elastic, even if the cutting tool 1 is tightened somewhat strongly, it can be prevented from compressing blood vessels and skin and obstructing blood circulation. It is preferable to use a cushioning material such as a sponge or absorbent cotton interposed therebetween to improve adhesion and soften the contact with the cutting tool 1.

Note that this cutting tool 1 can be used for fixing various types of bones such as the forearm bone, humerus bone, lower leg bone, clavicle, and rib bone.

As described above, according to this invention, the cutting tool is molded from a hard plastic plate, and both sides in the width direction are molded thinner than the middle part to maintain elasticity, and the cross section is formed into an arc shape. It is extremely sturdy and strong, and by bending and tightening both sides, it can adapt well to the size of the injured area that varies from person to person, and can be tightly wrapped and fixed without directly touching the skin. .

In addition, since it is molded from a plastic plate, it is extremely lightweight and does not take up much bulk, providing a light feeling of use, and is highly durable and can be used repeatedly. It is also easy to mold and manufacture at a relatively low cost (insurance (can be priced within the range of medical coverage) and has a good appearance.

Furthermore, it is water resistant and has good ventilation due to the ventilation holes, which prevents stuffiness in the injured area.
