Description

A cast capable of moving toe protection means after reshaping the splint molded body{GIPS}

The present invention provides support by firmly compressing and fixing part of the body for treatment by patients injured in leg injuries such as fractures, as well as hot water or hot water (water heated at high temperature) according to the size of the user's body. ) Through the re-molding, and accordingly, the moving and wearing of the toe protection means, relates to a cast capable of moving the toe protection means after the reshaping of the splint molded body.

In general, orthopedics, etc., in the case of fractures, sprains, inflammation, etc. in the limbs, etc., use a cast to fix the sore limbs so that they do not move.

These casts are divided into a whole cast splint that completely covers the affected area and a half-cast splint that covers only half of the affected area, depending on the type of treatment.

In particular, the whole cast splint is more effective in shaping the affected area because it completely wraps and fixes the affected area.

In the past, a whole cast splint in which a plaster-coated bandage was wrapped around and fixed to the affected part was widely used.These whole cast splints do not effectively support the affected part as shrinkage occurs in the process of curing the plaster, and a bandage is applied to the affected part. There was a problem in that it takes a considerable amount of time.

In addition, there is a problem of injuring the skin of the affected area because there is no ventilation at all, causing itching and unpleasant odor when sweating when fixed for a long period of time, and since a separate cutter must be used when removing after treatment is completed.

In addition, the conventional cast is made of a structure that cannot protect other body parts such as toes as only the affected area is protected.
