Medical gauze piece and production method thereof

Abstract

The invention discloses a medical gauze piece and a production method thereof. The medical gauze piece is made of a bamboo charcoal fiber material. The production method comprises the following steps of: (1) smoking, pre-drying, drying, pre-carbonizing, carbonizing, calcining, spraying and crushing fresh moso bamboo to form nano bamboo charcoal powder; (2) mixing the bamboo charcoal powder into polyester or viscose, stirring, drawing filaments containing the bamboo charcoal powder through wire drawing equipment, and thus obtaining bamboo charcoal fibers; (3) spinning the bamboo charcoal fibers into a gauze; and (4) folding the whole gauze, and thus obtaining the medical gauze piece. The medical gauze piece has high air permeability, bacteria resistance and water absorption, and can prevent the skin around a wound from wrinkling and whitening, effectively control propagation of the bacteria around the wound, effectively absorb exudation of the wound, keep the wound dry and clean and promote healing of the wound.

Description

technical field [0001] The invention relates to a medical dressing and a production method thereof, in particular to a medical gauze block and a production method thereof. Background technique [0002] Traditional medical gauze pieces are mainly composed of cotton cloth and cotton fibers, which are mainly used to bandage wounds and clean blood from wounds during operations. [0003] The cotton cloth and cotton fiber used in the current medical gauze block have poor air permeability, and the water vapor and sweat normally secreted by the human body cannot penetrate this layer of adhesive tape, so it has a soaking effect on the local skin, which is specifically manifested as wrinkling and whitening of the skin around the wound. , and cotton cloth and cotton fiber are not as absorbent as bamboo charcoal fiber (the data shows that the water absorption of bamboo charcoal fiber is 6 times that of cotton fiber), which means that the exudation of the wound cannot be effectively abso...

AI Technical Summary

Problems solved by technology

[0003] The cotton cloth and cotton fiber used in the current medical gauze block have poor air permeability, and the water vapor and sweat normally secreted by the human body cannot penetrate this layer of adhesive tape, so it has a soaking effect on the local skin, which is specifically manifested as wrinkling and whitening of the skin around the wound. , and cotton cloth and cotton fiber are not as absorbent as bamboo charcoal fiber (the data shows that the water absorption of bamboo charcoal fiber is 6 times that of cotton fiber), which means that the exudation of the wound cannot be effectively absorbed by the wound plaster, resulting in fluid accumulation in the wound, which provides a source for bacterial reproduction. suitable place

The cotton cloth and cotton fibers used in the current medical gauze block have no antibacterial properties, and a large amount of antibiotics are required after surgery or trauma
