Preparation method and application of quick absorption saturation gelation seaweed hemostatic dressing

Abstract

The invention discloses a preparation method of a quick absorption saturation gelation seaweed hemostatic dressing. The method includes the steps of: soaking, rinsing and drying on calcium fiber textile or non-woven products containing alginate, and the carrying out cutting, packaging and sterilizing to obtain the quick absorption saturation gelation hemostatic dressing. The invention also discloses the application of the quick absorption saturation gelation seaweed hemostatic dressing prepared by the above method. The invention is applicable to rapid absorption and removal of a large amount of surgical diffusate in surgical operation process, so as to realize the effects of rapid hemostasis and operation wound clean; the hemostatic dressing is used for burn, scald and other acute and chronic wounds, can cover the wound and prevent moisture loss in body fluids, provide a positive moist environment for wound healing, prevent the wound from effusion and erosion, isolate bacterial infection, and play the effects of stopping bleeding, relieving pain, promoting wound healing, and reducing scar.

Description

technical field [0001] The invention relates to a method for manufacturing a fast liquid-absorbing gelled seaweed hemostatic dressing, and in addition, the invention also relates to the application of the fast liquid-absorbing gelled seaweed hemostatic dressing. Background technique [0002] At present, absorbable calcium alginate medical dressings have been widely used in clinical wound hemostasis and nursing, and have significant advantages. Calcium alginate dressings are composed of calcium alginate fibers that are woven or needled. When in contact with the wound, ion exchange occurs between the calcium alginate fibers and the sodium ions in the pus, blood or exudate, and the water-insoluble calcium alginate is slowly transformed. It becomes water-soluble sodium alginate, so that a large amount of water enters the interior of the fiber to form a hydrogel, which plays the role of cleaning wound exudate, hemostasis and moist care of the wound. [0003] Hygroscopicity and g...

Problems solved by technology

However, it takes at least 30 minutes for the dressing made of ordinary calcium alginate fiber to absorb the exudate or pus and convert it into a gel, which is still difficult to meet for the wound cleaning and nursing of acute massive bleeding or exudate. requirements, restricting the clinical application of seaweed dressings

[0004] For this problem, the current technical solution is generally to modify the fiber by reducing the level of fiber calcification during spinning or blending into other absorbable materials, but the reduction of the degree of calcification or the introduction of blended substances often As a result, the strength of the fiber is reduced, the spinnability is reduced, and the difficulty of spinning, needle punching or weaving of the fiber is increased, and the requirements for the performance of production equipment such as spinning, needle punching, weaving, and slitting are also increased. At the same time, the above The improvement of the moisture absorption and gelation speed of the product obtained by the method is also relatively limited, and the problems of slow moisture absorption and slow gelation speed of the product cannot be completely solved.
