Embodiment 1

[0041] The present embodiment provides a kind of bamboo fiber hemostatic gauze, prepared according to the following method:

[0042] The whole system is 100g, and each component is weighed according to the following formula, the specific formula: 0.1g kaolin, 2g 1% hypromellose 2910-SHE50 (Hydroxypropyl methylcellulose, HPMC), 20g polyethylene glycol 600, 77.9g water Carry out mechanical stirring to make it fully mix to make 100ml each of 4 different kaolin concentration suspensions. Bamboo fiber gauze is cut into 7cm * 70cm (corresponding to 50ml above-mentioned suspension), as base material. Using the method of spray-freeze drying, 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 to obtain t...

Abstract

The invention relates to the technical fields of a medical dressing and a production process thereof, in particular to bamboo fiber hemostatic gauze and a preparation method thereof. The hemostatic gauze consists of a base material made from a raw or regenerated bamboo fiber material , a kaolin or kaolinite hemostatic clay material which is bonded to the base material and a binding agent for binding the hemostatic clay material to the base material. According to the hemostatic gauze disclosed by the invention, the base material in the bamboo fiber hemostatic gauze consists of bamboo fibers, the hemostatic clay material consists of kaolin or kaolinite and the hemostatic clay material is bonded to the bamboo fibers of the base material by virtue of the bonding agent, so that a stable nature is guaranteed, the hemostatic clay material is prevented from falling off easily, 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 bamboo fiber 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 necessary to base itself on domestic res...
