preparation example Construction

[0034] Please refer to figure 1 , the preparation method of the medical dressing material comprises: respectively putting alginate fiber, bamboo fiber, and viscose fiber into an opening machine for opening, so that the bonded fibers become fluffy and soft; Mixing to make it evenly fused; then carding through a carding machine; after laying the net, acupuncture, winding, and slitting to obtain the finished product.

[0035] Specifically, the above-mentioned preparation method comprises the following steps:

[0036] Opening: loosen, remove impurities, and open alginate fiber, bamboo fiber, and viscose fiber respectively;

[0037] Blending: put alginate fiber, bamboo fiber and viscose fiber into the box for blending;

[0038] Carding: Carding the fiber raw materials after opening;

[0039] Laying: laying the carded fiber raw materials into a web;

[0040] Acupuncture: Acupuncture the laid net, through pre-puncture, barb and main puncture, the fibers are entangled and reinforced...

Abstract

The invention discloses a medical dressing material and its preparation method. The medical dressing material comprises, by weight, 5-50% of alginic acid fiber, 1-15% of bamboo fiber and 40-90% of viscose fiber. The medical dressing material has effects of haemostasis and bacteriostasis, can absorb lots of pus and blood and form a humid microenvironment to promote growth and multiplication of cells and wound healing, is nonirritating to human body, and has no anaphylactic reaction. Especially by the application of bamboo fiber, wound infection and inflammation of patients are avoided due to natural antibiotic bacteriostasis effect of the bamboo fiber.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a medical dressing material and a preparation method thereof. Background technique [0002] At present, gauze, polymer film, hydrocolloid, etc. are mostly used as medical dressing materials on the market, but they also have problems such as easy passage of microorganisms and poor absorption and penetration capabilities. With the development of medical material technology, the research and application of new medical dressings are becoming more and more extensive. Alginate fiber has the properties of moisture absorption, hemostasis, and skin-friendly, and is currently the most ideal material for medical dressing materials. [0003] The utility model patent with the patent announcement number of 204275112U discloses an alginate medical dressing. The alginate composite film layer and the natural rubber layer are compounded. The surface of the alginate fiber film is coated ...
