Abstract
The invention relates to a fabrication method of a water-soluble hemostatic gauze, comprising the steps of pre-treatment, micro crystallization treatment, crosslinking reaction treatment, washing treatment and post treatment. The invention has the beneficial effect that the water-soluble hemostatic gauze has good water solubility, salt solubility and hemostatic property, can prevent adhesion in operation, has no stimulation to organism and is safe and reliable.
Description
Technical field
The present invention relates to a kind of preparation method of water-soluble gauze.
Background technology
Hospital gauze is a kind of important medical dressing commonly used, has that use amount is large, the characteristics of wide application.But conventional gauze can cause the problems such as environmental pollution of change dressings aggravation patient suffering, discarded gauze.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides a kind of preparation method of water-soluble gauze.
The present invention solves the technical scheme that its technical problem adopts: a kind of preparation method of water-soluble hemostatic gauze may further comprise the steps:
A, preliminary treatment: the gauze material is cotton fiber or xylon or bamboo fibre, and gauze is activated 2～3 hours with ethanol or acetone soln;
B, controlled micro crystallization are processed: place 40～50wt% sodium hydroxide solution to process 2～3 hours on pretreated gauze among a;
C, cross-linking reaction are processed: the gauze that controlled micro crystallization among the b is processed was processed 3～4 hours with containing the chloroacetic ethanolic solution of 50～60wt%;
D, carrying out washing treatment: the gauze that cross-linking reaction among the c is processed washs with 75% ethanolic solution, adds hydrochloric acid solution in the washing process and is neutralized to pH6.5～7.5;
E, post processing: the gauze of carrying out washing treatment among the d is soaked with isopropyl alcohol, oven dry, bake out temperature is 80～100 ℃.
The invention has the beneficial effects as follows: have good water-soluble, salt dissolubility and hemostatic, can prevent surgical adhesions, non-stimulated to body, safe and reliable.
The specific embodiment
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to illustrate the present invention rather than limitation of the invention further.
Embodiment 1:
A, preliminary treatment: the gauze material is cotton fiber or xylon or bamboo fibre, and gauze is activated 2～3 hours with ethanolic solution;
B, controlled micro crystallization are processed: place the 40wt% sodium hydroxide solution to process 2～3 hours on pretreated gauze among a;
C, cross-linking reaction are processed: the gauze that controlled micro crystallization among the b is processed was processed 3～4 hours with containing the chloroacetic ethanolic solution of 50wt%;
D, carrying out washing treatment: the gauze that cross-linking reaction among the c is processed washs with 75% ethanolic solution, adds hydrochloric acid solution in the washing process and is neutralized to pH6.5～7.5;
E, post processing: the gauze of carrying out washing treatment among the d is soaked with isopropyl alcohol, oven dry, bake out temperature is 80～100 ℃.
Embodiment 2:
A, preliminary treatment: the gauze material is cotton fiber or xylon or bamboo fibre, and gauze is activated 2～3 hours with acetone soln;
B, controlled micro crystallization are processed: place the 50wt% sodium hydroxide solution to process 2～3 hours on pretreated gauze among a;
C, cross-linking reaction are processed: the gauze that controlled micro crystallization among the b is processed was processed 3～4 hours with containing the chloroacetic ethanolic solution of 60wt%;
D, carrying out washing treatment: the gauze that cross-linking reaction among the c is processed washs with 75% ethanolic solution, adds hydrochloric acid solution in the washing process and is neutralized to pH6.5～7.5;
E, post processing: the gauze of carrying out washing treatment among the d is soaked with isopropyl alcohol, oven dry, bake out temperature is 80～100 ℃.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
