Description

Wound protection device

The present invention relates to a protective device, and more particularly to a wound protection device that can be attached to the surface of the skin and that protects the wound.

In general daily life, when there is a wound in the body, a wound patch is usually covered at the wound, and the conventional wound patch usually comprises a base layer, an adhesive layer coated on one side of the base layer, and a a gauze bonded to a partial region of the adhesive layer, and at least one release layer adhered to the adhesive layer. When the peeling layer is torn open during use, the wound patch can be adhered to the skin with the adhesive layer and covered on the outside of the wound.

However, according to many medical studies, it is found that the wounds of the body need to be regenerated by the epithelial cells of the skin. When the body has a wound, the body itself produces a repairing mucus containing a rich cell growth factor in the vicinity of the wound to help the wound heal. When a person has a wound in his body, he or she usually washes the wound and then applies the medicine, and then sticks the wound patch to the wound. Although this kind of wound treatment has been carried out for many years, the wound patch will directly abut on the wound, and the repairing mucus containing a large amount of abundant cell growth factors will be dried. When these repaired mucus are absorbed by the adhered gauze, it not only grows. Factors can't be freely detached, which can also hinder the recovery of the wound. In addition, when the gauze is directly adhered to the surface of the wound, the removed gauze will also pull the skin around the wound and the scarring part during the dressing change, which not only prolongs the wound healing time, but also causes pain in the dressing process. For reasons of investigation, although the wound patch can protect the wound, it can be used in contact with the wound of the skin, which will cause the wound healing time to lengthen.

The purpose of the present invention is to provide a wound protection device that can protect a wound and accelerate the healing of the wound.
