Embodiment Construction

[0009] The present invention is further described below:

[0010] A kind of medical chitosan antibacterial dressing, it is raw material with chitosan fiber, is sprayed on the chitosan fiber and is attached with silver-loaded nano-titanium dioxide particle, makes dressing product, and the weight of silver-loaded nano-titanium dioxide particle accounts for 0.1- 2%. The preparation method of the above-mentioned medical chitosan antibacterial dressing of the present invention, it sprays silver-loaded nano-titanium dioxide particles on the chitosan fiber, and then dries to obtain a product, and then cuts, packs, sterilizes, and obtains a finished product; the spraying process is: The chitosan fiber is spun-cut into short fibers-spraying silver-loaded nano-titanium dioxide on the chitosan short fibers-to make chitosan products. The specific process is (1), dissolving chitosan with dilute acetic acid solution, filtering, spinning through a spinneret, solidifying into chitosan fibers...

Abstract

The invention relates to a medical chitosan antiseptic dressing, which takes chitosan fiber as a raw materials and is prepared by the following steps of spraying silver-loaded nano titanium dioxide particles on the chitosan fiber to prepare a dressing product, wherein the silver-loaded nano titanium dioxide particles accounts for 0.1-2wt% of the dressing; and drying the dressing product, cutting,packaging, sterilizing to obtain the product. The spray technology is as follows: spinning the chitosan fiber, cutting into short fiber, spraying the silver-loaded nano titanium dioxide particles on the chitosan short fiber, and preparing into the chitosan product. The invention has the advantages of imbibing function, moisture function, hemostasis function and antibiosis capability, and is a good medical dressing.

Description

technical field [0001] The invention relates to a medical material and a preparation method thereof, in particular to a medical chitosan antibacterial dressing and a preparation method thereof. Background technique [0002] The current medical treatment of skin damage usually uses plant fiber gauze as a drug delivery carrier and covers it on the surface of the wound after taking it. This method is easy to adhere to the wound site due to plant fiber gauze, causing repeated damage to the skin while changing the dressing. At the same time, plant fiber gauze itself has no antibacterial properties and needs to be manually disinfected before taking the medicine; it has poor biocompatibility and degradability and must be removed. Along with the raising of living standard, traditional gauze can't satisfy people's need in bandaging wound. The emergence of chitosan functional dressings can improve the conditions of wound management and healing. [0003] Chitosan, also known as chiti...
