Embodiment 1

[0034] A medical dressing sheet, comprising the use of an alginate dressing, the alginate dressing is made of alginate fibers, and microporous polymeric fibers are attached to the fibers on one of the two sides of the alginate dressing. sugar granules;

[0035] In this example, 50 mesh-300 mesh microporous polysaccharide powder was evenly sprayed onto one side surface of the alginate dressing made of alginate fiber, and the other side surface was not sprayed with microporous polysaccharide powder. Porous polysaccharide powder, the microporous polysaccharide is prepared from modified starch, and the modified starch includes potato plant modified starch, tapioca modified starch, corn modified starch, etc., and the ratio of microporous polysaccharide to calcium alginate is 0.01 ~0.5:1, preferably 0.1:1, prepared into sheet polysaccharide alginate dressing, with a thickness of 0.5~5mm, preferably 1-2mm, more preferably 1-1.5mm.

[0036] A medical dressing device. The medical dres...

Embodiment 2

[0043]The difference between embodiment 2 and embodiment 1 is that the medical dressing sheet of embodiment 2 is cut according to a certain size, and then after being packed in a PETG hard plastic blister box, it is packed in an aluminum foil bag, an aluminum plastic bag or a PETG bag; That is, the dressing sheet of the present invention is packed in a hard plastic blister box, and then packed into an aluminum foil bag, an aluminum-plastic bag or a PETG bag, so that the medical dressing device of the present invention can be used in a wider range of environments, especially in humid environments. environment, it is easier to keep the aseptic state of the medical dressing sheet; other related technical features are not listed in embodiment 2, refer to embodiment 1.

Abstract

The invention relates to a medical dressing sheet, a medical dressing device manufactured by the medical dressing sheet, and a manufacture method. The medical dressing sheet uses an alginate dressingwhich is prepared from alginate fibers. The medical dressing sheet is characterized in that micropore polysaccharide particles are attached to fibers on one surface of surfaces on two sides of the alginate dressing. The medical dressing sheet and the medical dressing device are convenient in use. In addition, the manufacture method for the medical dressing device is simple in operation, the medical dressing sheet is good in wound fitting properties and high in stability, can quickly seal soft tissue wounds and is suitable for a wide wound surface range, a use environment is free from limitation, and the medical dressing sheet can realize self absorption, does not adhere to the wound surface so as to avoid cicatricial tissue hyperplasia, can quickly and effectively control wound surface liquid effusion, performs a function of protecting the wound surface, accelerating healing, and preventing infection, and has an important meaning for saving the lives of wounded people in a trauma emergency.

Description

Technical field: [0001] The invention relates to the field of biomedical materials, in particular to a medical dressing sheet, a medical dressing device prepared therefrom and a preparation method. Background technique: [0002] There are many kinds of medical dressings in the medical market, and their functions are single. They are easy to destroy the newly grown granulation tissue on the wound surface, affect the repair of the wound surface, and have the risk of scar hyperplasia, so their use is limited. With the further deepening of the research on the mechanism of wound repair, the use of various absorbable hemostatic materials to prepare medical dressings came into being. At present, absorbable polysaccharide hemostatic materials, soluble alginate hemostatic materials and composite hemostatic materials are research hotspots. Alginate hemostatic material can absorb a large amount of wound exudate, keep the wound in a moist environment, prevent exudate from seeping out, ...
