Problems solved by technology

Ordinary powder medicines have large particle size, large number of atoms in the particles, and few atoms distributed on the surface. When the ordinary powder medicine dressing is directly applied to the wound, it will not selectively absorb water molecules in the blood, and will Absorb other components in the blood, which will greatly increase the concentration time of platelet aggregation and coagulation factors, and its hemostatic effect is not very ideal

Abstract

The invention discloses a haemostatic wound dressing. The haemostatic wound dressing is prepared from cuttlebone made into nano-grade powder. The haemostatic wound dressing can also be prepared from rhizoma bletillae or pollen typhae or radix notoginseng which is made into nano-grade powder. The invention further discloses a preparation process for the haemostatic wound dressing. The preparation process comprises the following steps: washing the cuttlebone with water and drying; smashing the dried cuttlebone into the nano-grade powder; sterilizing the cuttlebone made into the nano-grade powder. The haemostatic wound dressing has the effects of shortening the generation time of thrombin, inhibiting the activity of fibrinolysin, contracting blood vessels and the like, and has the characteristics of rapid and reliable hemostasis and prevention of blood stasis in hemostasis; the conventional Chinese medicinal herbs are processed and modified into the nano-grade powder to obtain a novel functional hemostasis material for repairing blood vessels and tissues at bleeding positions.

Description

technical field [0001] The invention relates to a technique in the field of hemostatic dressing, in particular to a hemostatic dressing and a preparation process thereof. Background technique [0002] In the existing hemostatic dressings, the medicine is generally directly ground into a common powder, and then the medicine powder is sprinkled on the bleeding wound, and then the wound is bandaged. Ordinary powdered medicines have large particle size, large number of atoms in the particles, and few atoms distributed on the surface. When the ordinary powdered drug dressing is directly applied to the wound, it will not selectively absorb water molecules in the blood, and will Absorbing other components in the blood will greatly increase the concentration time of platelet aggregation and coagulation factors, and its hemostatic effect is not very ideal. Contents of the invention [0003] Based on this, it is necessary to propose a hemostatic dressing capable of rapid hemostasis...
