Embodiment 1

[0018] A chitin fiber medical dressing, composed of chitin fiber 1, synthetic fiber non-woven fabric 2 and pressure-sensitive adhesive non-woven fabric 3, one end of chitin fiber non-woven fabric 1 is compounded on synthetic fiber non-woven fabric 2 One end face of the synthetic fiber non-woven fabric 2 is covered with a pressure-sensitive adhesive non-woven fabric 3 .

[0019] When in use, the chitin non-woven fabric is directly wrapped around the part to be cared for, and then the two ends of the pressure-sensitive adhesive non-woven fabric are pasted on the skin of the human body and fixed. Because the invention adopts chitin as the raw material of the medical fiber dressing, the obtained product has good adhesion to the wound surface. Not only has the function of inhibiting pain and hemostasis, but also has the effect of antibacterial and anti-inflammatory. Simultaneously, the present invention can dissolve automatically and be absorbed by the body along with the healing ...

Abstract

The invention discloses a chitin fiber surgical dressing which is formed by chitin fibers, synthetic fiber non-woven fabrics and pressure-sensitive adhesive (PSA) non-woven fabrics in a composite mode. One end faces of the chitin fibers are arranged on one end faces of the synthetic fiber non-woven fabrics in a compounding mode, and the other end faces of the synthetic fiber non-woven fabrics are covered with the PSA non-woven fabrics. According to the chitin fiber surgical dressing, chitin is used as raw materials of a medical fiber dressing, and so that obtained products and the surface of a wound can fit well. Not only can the functions of restraining pains and hemostasis be achieved, but also the functions of antibacteria and anti-inflammatory are achieved. Meanwhile, the chitin fiber surgical dressing can be dissolved automatically and absorbed by an organism along with the healing of the wound, and the pains of patients are avoided.

Description

technical field [0001] The invention belongs to the field of biomaterials, in particular to a chitin fiber medical dressing. Background technique [0002] Tissue engineering is an emerging interdisciplinary field developed in the past 30 years. Its ultimate goal is to produce products for restoring, maintaining, or enhancing the structure and function of damaged organs or tissues in the human body. [0003] Chitin (polyethylene glycol) is a polysaccharide widely distributed in nature. It is the main component of the cell walls of various fungi and the shells of shrimps, crabs, and insects. It can be absorbed by body tissues after being decomposed by lysozyme in the body. unique performance. Raw materials widely exist in nature. The application of chitin in antibacterial aspects has also been reported. However, the chitin fiber medical dressing with wider application and better antibacterial effect has not been further reported in the prior art. In the prior art, relevant...
