Abstract

The invention discloses a medical dressing which comprises a dressing body, wherein the dressing body consists of medical cotton fiber and chitosan fiber. According to the medical dressing disclosed by the invention, a structure in which the dressing body is made from medical cotton fiber and chitosan fiber is skillfully adopted; since the medical cotton fiber is a traditional wound dressing in direct contact with the wound and is a safe traditional wound dressing, and the application of chitosan fiber in direct contact with wound lasts for 20 years and the safety is well verified, the medical dressing disclosed by the invention is safe and reliable to use, realizes a good effect in terms of liquid absorption, bleeding stopping, pain relieving, wound healing promotion and the like, and also has the functions of preventing adhesion and reducing scars while avoiding the problem of fiber shedding in the using process; moreover, the medical dressing disclosed by the invention is simple in structure, convenient to prepare, low in cost and easy to accept by the patients, thereby being an ideal functional medical dressing.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, and in particular relates to a medical dressing. Background technique [0002] Chitosan (chitosan) is obtained by deacetylation of chitin (chitin), which is widely present in nature, and is also known as chitin and chitosan. The chemical name is polyglucosamine (1-4)-2-amino-B-D glucose. Chitosan is derived from biological structure substances, has a strong affinity with human cells, and can be decomposed and absorbed by enzymes in the body. Human body has no toxicity and side effects. At the same time, because chitosan has important biological functions such as antibacterial, antibacterial, hemostasis, promotion of wound healing, and prevention of tissue and organ adhesion, it has been widely developed and used in the medical field and has become an excellent biomedical and pharmaceutical material. As a medical dressing, chitosan has the following advantages: 1. Hemostasis. The positi...
