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 hemostatic dressing, which comprises cuttlebone made into nanoscale powder and can also comprise bletilla made into nanoscale powder or pollen typhae made into nanoscale powder or pseudo-ginseng made into nanoscale powder. The invention also discloses a production method of the hemostatic dressing, which comprises the following steps of: cleaning cuttlebone with water and then drying the cuttlebone; crushed the dried cuttlebone into nanoscale powder; and sterilizing the cuttlebone made into the nanoscale powder. The hemostatic dressing has the advantages that the time for thrombin generation can be reduced, the activity of plasmin can be inhibited, the contraction of blood vessels can be realized, bleeding can be stopped rapidly and reliably with no blood stasis, traditional Chinese herbal medicine can be modified into nanoscale powder to prepare hemostatic materials with novel functions, and the blood vessels and tissues on bleeding parts can be recovered.

Description

Technical field [0001] The present invention relates to a technology in the field of hemostatic dressings, in particular to a hemostatic dressing and a manufacturing method thereof. Background technique [0002] Existing hemostatic dressings generally directly grind the medicine into ordinary powder, and then sprinkle the medicine powder on the bleeding wound, and then bandage the wound. Ordinary powder medicines have large particles, a large number of atoms in the particles, and few atoms on the surface. When ordinary powdered medicine dressings are directly applied to the wound, they will not selectively absorb water molecules in the blood, and will By absorbing other components in the blood, it will cause platelet aggregation and the concentration of clotting factors to increase greatly, and its hemostatic effect is not very ideal. Summary of the invention [0003] Based on this, it is necessary to propose a hemostatic dressing that can quickly stop bleeding and a manufacturin...
