Embodiment 1

[0011] (1) Solution A: 80% alcohol containing 2.5mol / L chloroacetic acid. Submerge the degreased gauze in the solution A at a temperature of 40-50°C and shake for 6 hours.

[0012] (2) Solution B: in 80% alcohol containing 4.0 mol / L sodium hydroxide. Put the gauze treated with solution A at a temperature of 40-50°C and shake for 6 hours.

[0013] (3) Wring out the gauze treated with solution B, put it into 95% alcohol, then adjust the pH value to 6.5-8.5 with concentrated hydrochloric acid; then immerse it in 95% alcohol, scrub it three times, wring it dry, and put it in the temperature of 25-30°C , Dry in a drying room with a humidity of 40-55°C; when the gauze is 90% dry, pull the gauze flat; after the gauze is completely dry, cut it according to different specifications and put it into a packaging bag.

[0014] (4) Gamma ray irradiation sterilization, the minimum absorbed dose is 25KGy.

Embodiment 2

[0016] (1) Solution A after titration embodiment 1 reaction is the 70% alcohol that contains 1.5mol / L chloroacetic acid. It is supplemented as 70% edible alcohol containing 2.5mol / L chloroacetic acid.

[0017] (2) Titration The solution B after the reaction of Example 1 is 80% alcohol containing 2.5mol / L sodium hydroxide. Make it up to 80% alcohol containing 4.0 mol / L sodium hydroxide.

[0018] (3) All the other steps are the same as in Example 1.

Embodiment 3

[0020] (1) Solution A after titration embodiment 1 reaction is the 70% alcohol that contains 1.6mol / L chloroacetic acid. Make it up to 70% alcohol containing 2.0mol / L chloroacetic acid.

[0021] (2) Titration The solution B after the reaction of Example 1 is 70% alcohol containing 2.2mol / L sodium hydroxide. Make it up to 70% alcohol containing 3.0 mol / L sodium hydroxide.

[0022] (3) All the other steps are the same as in Example 1.

Abstract

The production process of water soluble hemostatic gauze includes the following steps: placing the degreased gauze into ethyl alcohol containing chloroacetic acid, oscillating, then placing it into high-concentration ethyl alcohol, using concentrated acid to regulate pH value to 6.5-8.5, finally immersing it into high-concentration ethyl alcohol, washing, drying and sterilizing by gamma ray so as to obtain the invented product which can be used for various hemostatic operations, protecting surface of wound and preventing formation of adhesion, also can be used moisture-proof material.

Description

1. Technical field [0001] The invention relates to a production process of a medical dressing, in particular to a production process of a water-soluble hemostatic gauze. 2. Background technology [0002] At present, medical dressings are generally sterilized by degreasing gauze for use by medical and health departments. Such dressings become waste after use, which is not easy to rot and pollutes the environment for a long time. 3. Contents of the invention [0003] The purpose of the present invention is to provide a production process of water-soluble hemostatic gauze which can be completely dissolved in water and is beneficial to the absorption and utilization of animals and plants. [0004] The technical solution of the present invention is: the production process of water-soluble hemostatic gauze, comprising: placing the degreasing gauze in alcohol containing chloroacetic acid for oscillation; then placing it in alcohol containing sodium hydroxide for oscillation; then...
