Non-stick dressing and preparation method thereof

Abstract

The invention discloses a non-stick dressing. The non-stick dressing comprises a medical cotton base material and a hydrophilic anti-adhesion layer, the hydrophilic anti-adhesion layer is composed of a super-hydrophilic high polymer material, and the super-hydrophilic high polymer material comprises any one or more of polyvinylpyrrolidone, polyurethane, polyethylene glycol and polyvinylpyrrolidone. The non-stick dressing not only has hydrophilic and anti-adhesion effects, but also can improve the seepage absorption capacity of a medical cotton base material, reduce the adhesion of the dressing and the wound surface and relieve the dressing change pain of a patient, and meanwhile, no accidental substances are left on the wound and are easy to clean. The invention also discloses a preparation method of the non-stick dressing. The method comprises the following steps: firstly, dissolving the super-hydrophilic polymer material in a solvent to obtain a super-hydrophilic polymer solution; then drying the medical cotton base material, and soaking the medical cotton base material in the super-hydrophilic polymer solution; and after soaking is completed, squeezing to remove redundant liquid, airing or drying, and sterilizing to obtain the non-stick dressing. The method is simple to operate, low in cost, environmentally friendly and suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of medical hygiene / nanometer materials, and in particular relates to a non-stick dressing and a preparation method. Background technique [0002] Medical cotton base materials (such as medical absorbent cotton gauze, surgical gauze dressing, absorbent cotton non-woven fabric) are non-toxic, non-irritating, and have good biocompatibility, and are widely used in medical dressings. For scalded wounds, this kind of dressing is easy to stick to the wound, and changing the dressing is easy to cause pain to the patient and cause secondary damage to the wound. [0003] At present, in order to overcome the above problems, the dressing is usually soaked in liquid paraffin oil or medical vaseline (such as medical vaseline gauze) and other grease-based hydrophobic substances to reduce wound adhesion, but soaking such oily substances will make the dressing water-absorbent.

Problems solved by technology

[0002] Medical cotton base materials (such as medical absorbent cotton gauze, surgical gauze dressing, absorbent cotton non-woven fabric) are non-toxic, non-irritating, and have good biocompatibility, and are widely used in medical dressings. For scalded wounds, this kind of dressing is easy to stick to the wound, and changing the dressing is easy to cause pain to the patient and cause secondary damage to the wound

[0003] At present, in order to overcome the above problems, the dressing is usually soaked in liquid paraffin oil or medical vaseline (such as medical vaseline gauze) and other grease-based hydrophobic substances to reduce wound adhesion, but soaking such oily substances will make the dressing water-absorbent. (Ability to absorb exudate) and the speed of liquid absorption is reduced. At the same time, oily substances are easy to remain on the wound surface, making it difficult to clean and clean, and also affect the speed of wound healing.
