Problems solved by technology

In the article "Polylactic acid fiber modification by grafting polyvinylpyrrolidone on the surface", polyvinylpyrrolidone was grafted on the surface of partially hydrolyzed polylactic acid fiber to obtain a modified polylactic acid fiber with certain water absorption, but this method is not convenient for large-scale production. Large-scale production, and there is still a big gap in the water absorption of fibers compared with absorbent cotton, and further modification is required

Embodiment Construction

[0015] A medical cotton swab for high-efficiency moisturizing and anti-infection. It is composed of a cotton swab and a composite fiber cotton wrapped around the end of the cotton swab. The composite fiber cotton is made of the following parts by weight of raw materials: polylactic acid particles 15, bacterial cellulose 5 , Fine silica aerogel 1, hyaluronic acid 10, dopamine hydrochloride 5, Tris-HCl buffer solution appropriate amount, deionized water 200.

[0016] The preparation method of composite fiber cotton is:

[0017] (1) Mix the polylactic acid particles with bacterial cellulose and fine silica aerogel, stir evenly at a high speed, and then perform melt spinning. The spinning temperature is 225°C, and the spinning speed is 2000 m / min. Composite polylactic acid fiber with a diameter of 10μm for use;

[0018] (2) First take 100 parts by weight of deionized water into the reaction vessel, then add dopamine hydrochloride, stir until it is completely dissolved, add Tris-HCl buff...

Abstract

The invention discloses a medical cotton swab with efficient moisturizing and anti-infection functions. The medical cotton swab is composed of a cotton swab rod and composite cellucotton covering the end of the cotton swab rod. According to the medical cotton swab, the composite cellucotton made by cospinning polylactic acid grains, bacterial cellulose and micron sized silica aerogel replaces traditional absorbent cotton, the production cost is lowered, inherent deficiencies of the absorbent cotton are overcome, no harmful effect on the surface of a wound exists, the surface of the medical cotton swab is decorated with a polydopamine-hyaluronic acid polymer, the moisture retentivity of the wound can be improved, and the discomfortableness of the wound can be reduced. The medical cotton swab is good in hydroscopicity and moisture-penetrability, low in weight, high in strength, breathable, permeable, and capable of effectively improving the discomfortableness in use of traditional artificial fibers, preventing wound infection and accelerating wound healing.

Description

Technical field [0001] The invention relates to the technical field of medical cotton swabs, in particular to a medical cotton swab with high efficiency, moisture retention and infection prevention. Background technique [0002] Medical cotton swabs are a very common medical care product. They are obtained by rolling cotton swabs made of plastic sticks, paper sticks, wooden sticks and so on. The main functions are disinfection, sampling, etc., and they are widely used. Because cotton swabs are in direct contact with the wound, it has high requirements on the quality of absorbent cotton. The absorbent cotton used in traditional medical cotton swabs is mostly obtained by degreasing cotton with lye. Although it has good skin affinity and water absorption, it is It is natural cotton, which is easy to breed bacteria, and the production cost is relatively high. As a result, there are many sterile cotton swabs made of low-quality absorbent cotton on the market, which directly affects th...
