Multilayer shallow layer trauma special hydrophilic dressing

Abstract

The invention relates to a multilayered hydrophilic wound dressing for superficial wounds, which is a hydrophilic adhesive film layer formed by applying a composite coating made of medical-grade animal glues, medical-grade plant gums, hemostatic ingredients, bactericide diluent and plant fiber additives on a dressing material contacting a wound contact surface. The outer layer of the wound dressing is a dressing forming film layer for preventing the shrinkage of the wound dressing, the dressing forming film layer can be removed during application, and the wound dressing is uniformly perforated to drain excessive exudates or blood. The inventive wound dressing has improved adhesiveness and can well control the superficial wound infection.

Description

technical field [0001] The invention relates to a special hydrophilic dressing for multi-layered shallow wounds, which mainly includes a hydrophilic adhesive film layer formed by compound coating on the dressing material of the dressing contacting with the wound contact surface, and its outer layer is provided with a layer to prevent the dressing material from wrinkling. The shrinkable dressing shaping film layer is removed during use, and the dressing is evenly covered with meshes, which can drain excess exudate or blood, so that superficial wounds can be more effectively controlled infection, Debridement and promote wound healing. Background technique [0002] Check the current medical institutions for the treatment of external wounds of the human body, such as cuts, abrasions, surgical incisions, skin extraction areas, ulcers or burns, etc. It is usually necessary to cover or wrap sterilized dressings on the outside of such wounds to prevent Infected by external bacteria...

Problems solved by technology

Check again that the customary dressings used in current medical institutions all need frequent dressing changes. Most of them are still gauze or two-layer gauze sandwiching cotton pads made of sterilized cotton, wet compresses or bandages on the wound. Although superficial wounds have the effect of absorbing wound exudate, the exudate will ooze back to corrode the skin around the wound, which may cause infection or the absorbed exudate is easy to volatilize and make the gauze hard and hurt the wound. When changing the dressing, stick the gauze on the On the wound, removing it not only causes pain to the patient, but also damages the loss of new granulation tissue in the wound, so it is necessary to try to solve it
