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

Embodiment Construction

[0014] see figure 1 , figure 2 As shown, dressing 1 of the present invention is made up of: dressing material shaping film layer 2, dressing material 3 and compound hydrophilic adhesive film layer 4, and dressing material shaping film layer 2 is to prevent dressing material 3 from shrinking, needs to be used during use. It can be made of PE membrane (PE membrane); the dressing material 3 is a soft, elastic, waterproof and breathable transparent film, which can be made of PU membrane (PU membrane), and the compound hydrophilic gel membrane (Hemostatic hydrophilic gel membrane) ) Layer 4 mainly uses medical-grade animal glue (such as collagen, hyaluronic acid, etc.), medical-grade vegetable glue (such as pectin, aloe extract, seaweed glue, etc.) (you can also choose to use medical-grade animal glue or medical-grade vegetable glue ), hemostatic agent formula (such as calcium salt, calcium citrate, etc.), bactericidal and antibacterial diluent (such as diluted silver ion, AgNo3,...

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 present invention relates to a special hydrophilic dressing for multi-level shallow wounds, which mainly has a hydrophilic adhesive film layer formed by a compound paint on the dressing material of the dressing in contact with the wound contact surface, and its outer layer has an anti-aging dressing material. The shrunken dressing shaped film layer is removed during use, and the dressing is evenly covered with mesh, which can drain excessive exudate or blood, so that superficial trauma wounds can be more effective in controlling infection , debridement and promote wound healing. Background technique [0002] Check the current medical institutions for the treatment of external trauma to the human body, such as cuts, abrasions, surgical incisions, skin harvesting areas, ulcers or burns, etc., it is usually necessary to cover or wrap sterilized dressings on the wounds to prevent Infected by external bacteria. Check again that the customary dressings...
