Description

Medical dressing pad pasting

Technical Field

The utility model relates to the technical field of medical supplies, concretely relates to medical dressing pad pasting.

Background

The medical dressing is used for covering sore, wound or other damaged skin wound surface, and is a medical material for dressing wound. The materials commonly used in the medical dressing at present comprise natural materials, artificial synthesis materials, medicinal dressings and dressings for fixation. The adhesive film dressing is one of the fixing dressings.

The adhesive materials generally used for fixation include adhesive bandages and gauze, acrylic adhesive tape, zinc oxide rubber cloth, and the like. The adhesive bandage and gauze are made by coating a layer of adhesive (rubber, polyacrylic acid) on fabric, non-woven fabric or plastic film to achieve the function of adhesion. Adhesive bandages are elastic bandages that have been coated with a particulate dispersion of natural latex that adheres to itself but does not adhere to the skin or clothing during use.

Patent CN 106714745 a discloses a medical dressing, which comprises an adhesive layer facing the skin surface, and the adhesive film has anti-inflammatory and analgesic effects, but the adhesive film has no good extensibility and is greatly limited when the wounded part moves during the use process; in addition, the dressing has limited water absorption, but when the blood or the exudate of the wound is more, the medicine in the dressing film is often not released completely and needs to be replaced, so that the resource waste is caused, and the operation is troublesome.

Patent CN 109172149A discloses an alginate dressing subsides, and its dressing subsides body includes pressure sensitive adhesive layer, medical unwoven cloth layer, and wherein medical unwoven cloth layer and pressure sensitive adhesive layer interlude set up oval-shaped dressing and deposit the holding chamber, can be fixed in the surface of a wound with antibiotic powder sodium alginate powder and antibiotic powder, and is convenient to use. However, the dressing patch with the structure still has the defects of poor extensibility and poor water absorption.

Therefore, there is a need to develop a dressing film with good extensibility and water absorption, and also with anti-inflammatory and antibacterial effects.

SUMMERY OF THE UTILITY MODEL

In order to solve the existing problems, the utility model provides a medical dressing film.

The utility model discloses a following technical scheme realizes.

A medical dressing film comprises an adhesive layer, an aseptic layer, an antibacterial layer and a liquid-absorbing dry layer, wherein the adhesive layer is in contact with injured skin, one surface of the adhesive layer is in contact with the skin, the other surface of the adhesive layer is bonded with the aseptic layer, the antibacterial layer is arranged outside the aseptic layer, and the antibacterial layer contains antiviral, bacterial, fungal and other medicines; and a liquid absorption drying layer is also arranged outside the antibacterial layer.

The adhesive layer is in a continuous U-shaped design, and the joint of the lower concave surface at the bottom of the U-shaped adhesive layer and the injured skin and the upper convex surface at the top of the U-shaped adhesive layer are adhered to the sterile layer into a whole.

Preferably, the drying layer is a super absorbent resin SPA film layer.

Preferably, the drying layer is a polyvinyl alcohol PVA absorbent cotton layer.

Preferably, the drying layer is a water-absorbent fiber non-woven fabric layer.

Preferably, the adhesive of the adhesive layer is a silicone adhesive.

Preferably, the antibacterial layer is a silicone gel layer containing an active agent.

More preferably, the active agent comprises an antibiotic, an antibacterial agent and an antifungal agent.

The utility model has the advantages that:

the dressing film of the utility model is divided into four layers, wherein the viscous layer is in a U-shaped design, is not completely adhered to the skin, and a gap is formed between the upper convex surface and the lower concave surface of the viscous layer, thereby promoting the air circulation and increasing the air permeability; in addition, when the adhesive layer moves at the wound position, the adhesive layer can stretch, and secondary pain of a patient caused by tearing between a wound and a pad pasting due to the fact that the traditional pad pasting material cannot stretch is overcome.

When the blood and the exudate of the wound wet the aseptic layer and enter the antibacterial layer, the medicine in the antibacterial layer starts to be released, so that the wound dressing has the anti-inflammatory and antibacterial effects, and the probability of wound infection is reduced; when the whole sterile layer is soaked by excessive blood of the wound, the outermost dry layer can absorb excessive water, so that the wound is kept dry, and the wound healing is accelerated.
