Embodiment 1

[0015] The content of calcium alginate fiber is 92.0%, and the content of chitosan fiber is 8.0%. Firstly, the calcium alginate fiber and chitosan fiber are loosened and mixed evenly, and then carded into a fiber web by a carding machine and laid flat, and then needled. The process is processed into non-woven sheets, and finally cut into sheets (7.5×7.5cm) by a cutting machine.

Embodiment 2

[0017] The content of calcium alginate fiber is 81.5%, and the content of chitosan fiber is 18.5%. First, the calcium alginate fiber and chitosan fiber are loosened and mixed evenly, and then carded by a carding machine to form a fiber web and laid flat, and then needled. The process is processed into non-woven sheets, and finally cut into sheets (10×10cm) by a cutting machine.

Embodiment 3

[0019] The content of calcium alginate fiber is 68.5%, and the content of chitosan fiber is 31.5%. First, the calcium alginate fiber and chitosan fiber are loosened and mixed evenly, and then carded by a carding machine to form a fiber web and laid flat, and then needled. The process is processed into non-woven sheets, and finally cut into sheets (8×8cm) by a cutting machine.

[0020] The medical functional biological dressing sheets prepared in the above-mentioned examples 1 to 3 were found through trial comparison that when the content of calcium alginate fiber was 81.5%, and the content of chitosan fiber was 18.5%, the functional biological dressing sheets prepared had The antibacterial effect is the most significant, it does not adhere to the wound, and better promotes wound healing.

Abstract

The invention relates to a medical functional biological dressing and a preparation method thereof. The medical functional biological dressing comprises the following components: 68.5%-92.0% of calcium alginate fiber and 8%-31.5% of chitosan fiber. The preparation process comprises the following steps of: firstly, opening the calcium alginate fiber and the chitosan fiber and uniformly mixing; secondly, carding the fiber to form fiber webs by using a carding machine, paving the fiber webs and processing into non-woven fabric pieces by using a needle-punching process; and finally, cutting the non-woven fabric pieces into pieces by using a cutting machine. With adoption of the calcium alginate fiber and the chitosan fiber as the raw materials, the medical functional biological dressing provided by the invention has the advantages of good biocompatibility and excellent ability of absorbing effusion; a large amount of wound effusions can be rapidly absorbed to form gel, and thus a wet healing environment is provided for speeding healing of wound or wound surfaces; and the medical functional biological dressing has the capability of rapidly clotting blood and stopping bleeding and good antibacterial properties.

Description

Technical field [0001] The invention involves a functional biological dressing and preparation method directly used for wounds. Background technique [0002] Self -stick elastic bandage is a elastic bandage with good self -adhesive and breathable performance. It has been widely used in sports protection, medical bandage and industrial operation protection.The patent number is 00117267.0 China's patent disclosure a self -stick elastic bandage with natural latex spraying natural latex. This elastic bandage has the advantages of convenient use, good breathability, and smooth bandaging. [0003] However, the self -adhesive elastic bandage cannot directly contact the wound and wound. When using the self -stick elastic bandage to treat the wound and wound, you need to use the dressing. Invention content [0004] The purpose of the present invention is to overcome the lack of existing technologies, and provide a medical functional biological dressing and preparation method that is dire...
