Abstract

The invention belongs to the technical field of medical dressings and specifically relates to antibacterial and anti-adhesion hydrocolloid oily yarn and a preparation method thereof. The antibacterialand anti-adhesion hydrocolloid oily yarn provided by the invention is prepared from a base material and a hydrocolloid component, wherein the base material is mesh polyester fiber; the hydrocolloid component is prepared from the following components in parts by mass: 10-20 parts of sodium carboxymethyl cellulose, 4-10 parts of imbibition accelerator, 0.6-5.5 parts of antibacterial agent, 10-20 parts of acetic acid aqueous solution with mass fraction of 1%, 5-10 parts of high-density polyethylene, 10-20 parts of liquid paraffin, 30-50 parts of vaseline, 5-20 parts of glycerin and 5-10 parts ofwool fat; the antibacterial agent is prepared from chitosan and polyhexamethylene guanidine. The antibacterial and anti-adhesion hydrocolloid oily yarn provided by the invention can provide a closedwet healing environment for a wound, and has a function of stopping bleeding and preventing bacteria and adhesion as well as remarkable imbibition ability to promote wound healing.

Description

technical field [0001] The invention belongs to the technical field of medical dressings, and in particular relates to an antibacterial and anti-adhesion hydrocolloid oil yarn and a preparation method thereof. Background technique [0002] The main function of medical dressings is to cover and protect damaged skin while providing an environment conducive to wound healing. Traditionally, natural fibrous dressings such as absorbent cotton gauze, gauze strips, cotton balls, and cotton membranes are mainly used, which can dry the wound and have the function of physical isolation; and new wounds, as well as problems such as bacterial growth, poor moisturizing and hemostatic performance. [0003] Chinese patent CN104258457B discloses a kind of hollyhock oil gauze. The preparation method of the hollyhock oil gauze is as follows: soak the medical degreasing gauze in the hollyhock compound base seed oil, and sterilize it at high temperature; The mass ratio is 1-3:1; the soaking tim...
