Abstract

The present application relates to a dissolvable hemostatic gauze, comprising sequentially stacked protective layers, a hollow fiber structure body and a release layer; the hollow fiber structure body is a soluble gauze, and the hollow fiber structure body includes sodium carboxymethyl cellulose , seaweed fiber and chitin fiber. The above-mentioned soluble hemostatic gauze, on the one hand, adopts a protective layer to protect the contact surface between the hollow fiber structure body and the position to be hemostatic, and on the other hand, uses a release layer to protect the other side of the hollow fiber structure body away from the position to be hemostatic, so that the above-mentioned soluble The hemostatic gauze can discard the release layer after use, and the above-mentioned soluble hemostatic gauze can be left in the body if necessary. On the other hand, it adopts an absorbable hollow fiber structure body design, which is conducive to blood coagulation and hemostasis, which in turn is beneficial to the above-mentioned soluble hemostatic gauze. is absorbed.

Description

technical field [0001] The application relates to the field of medical materials, in particular to a soluble hemostatic gauze. Background technique [0002] Soluble hemostatic gauze is a kind of gauze suitable for hemostasis inside and outside the body. It can absorb the water in the blood to expand and form a gel, which can be attached to the wound surface of the bleeding port to block and seal the ends of small blood vessels and capillaries to achieve the purpose of assisting hemostasis. . Along with technical research, many soluble hemostatic gauzes have been put on the market. Currently, Johnson & Johnson’s instant yarn hemostatic gauze is the best sold in the body. There are also many patent documents related to soluble hemostatic gauze. The brief introduction is as follows. [0003] For example, the Chinese patent with the publication number CN2855395Y discloses a band-aid comprising soluble hemostatic gauze, which consists of a layer of soluble hemostatic gauze attac...
