Embodiment 1

[0032] Immerse 100 grams of chitosan fiber in 45% NaOH solution, bath ratio 1: 20, react at room temperature for 1 hour, generate alkalized chitosan fiber, react this product with chloroacetic acid in isopropanol, the concentration of chloroacetic acid 25%, the reaction temperature is 60 DEG C, and the reaction time is 3 hours. After the reaction is completed, the excess solution is removed, washed with absolute ethanol, and air-dried to obtain carboxymethyl chitosan fiber. This product is made into 50g / m by opening, netting and needle punching 2 The dressing can be cut, packaged and sterilized. Suitable for wounds less than 10cm 2 the wound.

Embodiment 2

[0034] See Example 1 for the preparation method of carboxymethyl chitosan fiber. According to 8:2, chitosan fiber and carboxymethyl chitosan fiber are mixed, opened, netted and needle-punched to make 100 g / m 2 The dressing can be cut, packaged and sterilized. It is suitable for burns and scalds with relatively large trauma.

Embodiment 3

[0036] When making the chitosan fibers added in Example 2, add nano-scale silver particles in a ratio of 0.5% in the spinning solution to make chitosan fibers and carboxymethyl shells containing nano-silver particles Polysaccharide fiber blended nonwoven medical dressing.

Abstract

An antibacterial medical dressing is prepared from chitosan fibers through alkalizing, etherifying reaction on chloroacetic acid to obtain carboxymethyl chitosan fibers, opening, netting, needling, and cutting by needed sizes, packing and disinfecting. It can be used for preparing the surgical dressing for wound, bum and scald, the anti-inflammatory staltic fiberous ball, anti-inflammtory drainage sliver, and operation dressing.

Description

technical field [0001] The invention relates to a method for manufacturing a medical dressing, in particular to a method for manufacturing an antibacterial medical dressing; in addition, the invention also relates to the use of the antibacterial medical dressing. Background technique [0002] For a long time, surgical dressings are mainly sterilized cotton and cotton gauze, which have certain limitations in their application. Cotton gauze itself does not have the ability to resist the reproduction of microorganisms. Although it has been sterilized, it is easy to be infected with bacteria during use. These traditional dressings will adhere to the wound during use, and even grow in the new granulation. Cause the patient's pain and the generation of new wound surface in changing dressing process. These traditional dressings also leave some debris after use, which affects wound healing. Dressings made of other synthetic materials suffer from the same drawback. [0003] When ...
