Abstract

The invention discloses an absorbable hemostatic dressing. Comprising the following raw material components in parts by weight: 50-100 parts of hydroxyethyl chitin, 30-80 parts of ossein, 3-10 parts of eel blood extract and 3-10 parts of longflower stringbush root extract. The prepared hemostatic dressing is good in absorbability, wound swelling and infection can be effectively avoided after hemostasis, and few scars are left after healing; the combined use of the eel blood extract and the longflower stringbush root extract prolongs the hemostasis time, and the combined use has a synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of dressing material preparation, in particular to an absorbable hemostatic dressing and a preparation method thereof. Background technique [0002] For the treatment and care of skin wounds, if the symptoms are mild, you can use "wound patches" to apply, or use Kangfuxin liquid or Yunnan Baiyao, etc. Kangfuxin liquid is suitable for trauma, ulcers, fistulas and other wounds. The gauze is soaked and covers the skin wound. If the wound is large, it needs to be debridement before use. Yunnan Baiyao is suitable for hemostasis and swelling of knife wounds, gunshot wounds and bruises, and can be used directly on the affected area. The above-mentioned various forms of hemostatic dressings have problems such as long hemostasis time, easy infection of bacteria and inflammation, excessive swelling in wound tissue fluid soaking time, difficult absorption of hemostatic dressing materials, and large scars after wound h...
