Alginate adhesive bandage and manufacturing method of alginate adhesive bandage

Abstract

The invention discloses an alginate adhesive bandage and a manufacturing method of the alginate adhesive bandage. The adhesive bandage consists of a waterproof fabric, a medical acrylic glue water layer, a 100-percent alginate non-woven fabric and protection paper, wherein the weft elasticity of the waterproof fabric is greater than 150 percent, the medical acrylic glue water layer is arranged at one side of the waterproof fabric in a coating way, the 100-percent alginate non-woven fabric is arranged on the medical acrylic glue water layer, and the isolation paper covers the medical acrylic glue water layer and the 100-percent alginate non-woven fabric. Water absorption cotton used by the alginate adhesive bandage is formed by the non-woven fabric produced by 100-percent alginate. Compared with an ordinary adhesive bandage, the alginate adhesive bandage has the advantages that the self sterilization and biodegradation effects are realized, a liquid-state protection film is formed on the surface of a wound, and the wound adhesion can be avoided. Therefore the use of an anti-sticky film is not needed, and the alginate adhesive bandage belongs to a fire-new waterproof, heeling-promoting and self-sterilization alginate adhesive bandage capable of forming the protection film on the surface of the wound.

Description

technical field [0001] The invention relates to an alginate wound dressing which is waterproof, promotes healing, self-sterilizes and forms a protective film on the wound surface and a manufacturing method thereof. Background technique [0002] Human living standards are getting higher and higher, and the requirements for medical care are also getting higher and higher. The best solution for small traumas in life is to be able to deal with them directly, and this has given birth to the rise of bandage products. The structure of the existing bandage is as attached to the instruction manual. figure 1 As shown, hot-melt glue is coated on a fabric with no elasticity, water-absorbing cotton is placed on the glue, and a layer of anti-adhesive plastic film is compounded on the water-absorbing cotton. There are following problems in such structure: (1) the viscosity is not enough; Existing bandages all adopt medical hot-melt adhesive as the carrier of viscosity, and although the pr...

AI Technical Summary

Problems solved by technology

There are following problems in such structure: (1) the viscosity is not enough; Existing bandages all adopt medical hot-melt adhesive as the carrier of viscosity, and although the production process of medical hot-melt adhesive is relatively simple, due to the inherent stickiness of medical hot-melt adhesive Unstable, and the stickiness is extremely poor. After sticking to the human body, if you sweat or exercise slightly, or in the case of external friction, it will directly fall off. If it is exposed to water, it will directly lose its stickiness.

(2) The fabric is non-waterproof and lacks elasticity; after the wound is applied, in order to prevent wound infection, water should be avoided as much as possible. Coating hot melt adhesive on the waterproof fabric, due to the existence of waterproofing agent, the bonding fastness between the hot melt adhesive and the fabric will be insufficient, and the technical problem of glue falling off is faced; at the same time, the existing fabric has insufficient elasticity, generally below 20%. , the comfort is not enough when using, and the foreign body sensation is strong. After the covered part is bent, it is easy to form a gap on the edge, and lose the protective function of the bandage

(3) After the absorbent cotton of cotton material is in contact with the damaged wound for a period of time, it is easy to form adhesion with the wound exudate, so it must be peeled off to clean the wound, causing secondary damage

The solution to the existing wound dressing is to add a layer of anti-adhesive plastic film on the cotton absorbent cotton, which will cause the problem of insufficient water absorption, resulting in the inability to completely absorb the wound exudate and affecting the repair of the wound

In addition, the absorbent cotton can only isolate the wound from the air to form a limited protection for the wound. Sometimes due to the existence of the anti-adhesive plastic film, the absorbent pad and the wound cannot be completely sealed, and bacteria are easy to invade and cannot promote wound healing.
