Embodiment 1

[0054] Present embodiment provides a kind of method that adopts natural bamboo fiber to manufacture water-soluble gauze as raw material, specifically comprises following five steps:

[0055] Step 1: Gauze pretreatment:

[0056] Preparation materials: 1200 grams of natural bamboo fiber material, 4500 ml of 95% (v / v) ethanol solution.

[0057] Pretreatment: Put the natural bamboo fiber material into a glass container, let the gauze spread out as much as possible, do not overlap, then slowly pour ethanol along the glass container wall, tamp it with a glass rod, so that the gauze is completely soaked.

[0058] Step 2: Alkaline treatment of gauze:

[0059] Preparation of alkali reaction solution: prepare 4800ml of 40wt% sodium hydroxide solution with sodium hydroxide and water, stir with a glass rod until completely dissolved and become clear and transparent, then cool the reaction solution to 20°C with cold water, seal it for later use.

[0060] Place the pretreated gauze raw ma...

Embodiment 2

[0072] 40wt% sodium hydroxide solution was selected for the alkalization treatment of gauze, and other operations were the same as in Example 1. The obtained water-soluble hemostatic gauze has a mass per unit area of ​​90g / m 2 , 20ml per gram of water absorption, and other test results are the same as in Example 1.

Embodiment 3

[0074] Select 75wt% ethanol solution of chloroacetic acid for use in the gauze ether reaction, and other operations are the same as in Example 1. The obtained water-soluble hemostatic gauze has a mass per unit area of ​​75g / m 2 , 28ml per gram of water absorption, and other test results are the same as in Example 1.

Abstract

The invention relates to the field of medical supplies, and particularly relates to a manufacturing method of water-soluble bamboo-fiber hemostatic gauze. The method comprises five procedures of pretreatment, an alkali reaction, an ether reaction, washing treatment and post treatment. The manufacturing method is a method for producing hemostatic gauze, which is simple in production process, relatively few in the kinds of used raw materials and reagents, and further better in effects, particularly in degradation effects.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a method for making water-soluble natural bamboo fiber hemostatic gauze. Background technique [0002] With the rapid development of health care and medicine, the requirements for medical equipment are gradually developing in the direction of high, refined and beautiful. Medical gauze is an important commonly used medical dressing, which has the characteristics of large usage and wide application. However, when it comes to various departments such as surgery, facial features, gynecology, and burns, many problems and accidents caused by conventional gauze cannot be solved for a while, such as repeated infection of the dressing, exacerbating the suffering of patients due to dressing changes, and the negligence of medical staff. Cause the viscera to be left over and lead to serious trouble, the environmental pollution of discarded pus and blood gauze and so on. Therefore, the inter...
