Embodiment 1

[0042] The present embodiment provides a kind of bamboo fiber hemostatic gauze, prepared according to the following method:

[0043] The whole system is 100g, and each component is weighed according to the following formula, the specific formula: 0.5g kaolin, 0.3g notoginseng hemostatic powder, 2g1% hypromellose 2910-SHE50 (Hydroxypropyl methylcellulose, HPMC), 20g polyethylene glycol Alcohol 600, 77.2g water; carry out mechanical stirring to make it fully mixed to make a suspension of 100ml. Bamboo fiber gauze is cut into 7cm * 70cm, as the base material. Using the spray-freeze drying method, spray about 50ml of the above suspension on the substrate with a nozzle with an inner diameter of 0.4mm and 80 holes. The ambient temperature is constant at 25°C and the spraying time is 30min. Dipping, the soaking time is 60min. Take out the gauze and put it into a freeze dryer, and freeze it for 24 hours under the condition of 223K. Finally, the prepared compound notoginseng kaolin ...

Abstract

The invention relates to the technical field of medical dressings and production processes of medical dressings, and in particular relates to a compound pseudo-ginseng, kaolin and bamboo fiber hemostatic gauze and a preparation method thereof. The hemostatic gauze comprises a base material, a hemostatic material and a binding agent, wherein the base material is made of a raw or regenerated bamboo fiber material; the hemostatic material is bonded to the base material; the binding agent is used for binding the hemostatic material to the base material; and the hemostatic material comprises a kaolin or kaolinite hemostatic clay material and pseudo-ginseng hemostatic powder. The base material of the hemostatic gauze provided by the invention comprises bamboo fiber, the hemostatic material comprises kaolin or kaolinite and pseudo-ginseng hemostatic powder, and the hemostatic clay material and the pseudo-ginseng hemostatic powder are bound to the bamboo fiber of the base material by using the binding agent, so that the hemostatic gauze is stable in property, the hemostatic clay material or the pseudo-ginseng hemostatic powder is not easy to drop off, and the hemostatic gauze is good in hemostatic effect.

Description

technical field [0001] The invention relates to the technical field of medical dressings and production techniques thereof, in particular to a compound notoginseng kaolin bamboo fiber hemostatic gauze and a preparation method thereof. Background technique [0002] Blood loss is the primary factor of traumatic death, and at least 30% of the wounded who died due to excessive blood loss can be saved if timely and effective hemostasis can be achieved. Blood loss is also the main cause of traumatic death such as war wounds and falling injuries. Successful hemostasis within an effective time is of great significance to saving lives. All countries in the world attach great importance to the research on post-traumatic hemostasis measures. But at present the hemostatic gauze that domestic emergency is used still stays at the level of non-woven gauze, there is still no effective, composite hemostatic gauze that can be used for first aid so far. In order to solve this problem, it is n...
