Self-Adhesive and Functional Skin Protection Bandages {Orthopedics Functional Undercast Padding}

The present invention relates to a self-adhesive and functional skin care bandage, and more particularly, can be provided to the patient by wearing a wound around the skin for the purpose of skin protection under the orthopedic splint coated with a water-curable polyurethane resin. Orthopedic self-adhesive and functional skin care bandages.

In general, one of the conventional methods for the cast of the fracture patient is to cut and cover the skin contact cloth, Starkinnet, which is composed mostly of cotton on the contact area, and then wrap the cotton bandage appropriately. The method of hardening by winding several times a plaster bandage, a water-curable casting tape, etc. has been common.

However, in the conventional cast treatment, as the cotton bandage is wound in a spiral shape several times over a certain thickness on the starkinnet, which is a skin protection cloth, the air permeability or drying speed is decreased, and thus, even after the procedure, the shower or the face wash or the external environment. Disadvantages of sweat discharge from the affected area, such as itching, frustration and bad smell to the patient, and also high risk of secondary infection such as skin sores and blisters or breeding of bacteria due to long-term wear. In addition, it is often found that the patient feels uncomfortable and frustrated, such as not taking a shower or getting water on the treatment area while wearing the cast.

In order to alleviate the above drawbacks, various types of skin protection cloth products have been suggested that can simultaneously express the role of skin protection cloth, Starkinet and cotton bandages, but most of them are also used by winding several times over the affected area. Therefore, there is a problem in that it is insufficient to solve the above problems such as lowering of breathability or secondary infection.
