Abstract
The invention discloses a method for preparing a fast haemostatic dressing. The method comprises the following steps: 1, taking sodium carboxymethylcellulose and carboxymethyl chitosan, uniformly mixing the sodium carboxymethylcellulose and carboxymethyl chitosan at normal temperature to form a mixture A; 2, vibrating the mixture A through mixing in the step 1 through a vibrating screen, and uniformly applying the mixture A on a sticky medical breathable adhesive plaster; 3, taking calcium alginate fibers and carboxymethyl chitosan fibers, cutting the calcium alginate fibers and carboxymethyl chitosan fibers into short fibers, loosening and uniformly mixing, and needling the short fibers into non-woven fabric; 4, allowing the non-woven fabrics to cover the surface of the breathable adhesive plaster to which the mixture A is attached, and forming a finished product.
Description
Technical field
The present invention relates to a kind of preparation method of quick hemostatic dressing.
Background technology
Hemorrhage, injured hemorrhage all can the generation because of the critical life of Massive Bleeding in soldier battlefield of unexpected wound, traffic accident, therefore needs a kind of wound dressing for first-aid fast hemostasis in the wild.
Summary of the invention
The invention provides a kind of preparation method of quick hemostatic dressing, it not only treats hemostatic wound successful, and easy to use.
The present invention has adopted following technical scheme: a kind of preparation method of quick hemostatic dressing, it comprises the following steps: step 1, get sodium carboxymethyl cellulose and carboxymethyl chitosan, sodium carboxymethyl cellulose and carboxymethyl chitosan are uniformly mixed to form to mixture A at normal temperatures; Step 2 is evenly added in mixed mixture A in step 1 on sticking medical air-permeable adhesive plaster after shaker vibration; Step 3, gets calcium alginate fibre and carboxymethyl chitosan fiber, cuts into short fiber, and then mix homogeneously after shredding becomes non-woven fabrics by short fiber acupuncture; Step 4, is then stained with non-textile mulch on the surface of mixture A at Breathable adhesive tape, form finished product.
In described step 1, sodium carboxymethyl cellulose is 100-120 gram, and carboxymethyl chitosan is 60-70 gram, and the particle diameter of mixture A is 200-300 order.In described step 2, on the medical air-permeable adhesive plaster of every square metre, to add mixture A be 300-500 gram and make that mixture A part is full and uniform to be bonded on medical air-permeable adhesive plaster.In described step 3, calcium alginate fibre is 100 grams, carboxymethyl chitosan fiber is 40 grams, calcium alginate fibre and carboxymethyl chitosan fiber cut into the short fiber that length is 65-80, mix homogeneously after shredding, and every square metre of described non-woven fabrics is containing 120 grams, short fiber.
The present invention has following beneficial effect: the present invention adopts sodium carboxymethyl cellulose, calcium alginate fibre, a kind of quick absorbing blood that the material such as carboxymethyl chitosan fiber and carboxymethyl chitosan forms is the hemostatic material of its a kind of high absorption of solidifying, its production cost is low, easily degraded, treatment hemostatic wound effect, being convenient to patient uses, after carboxymethyl chitosan of the present invention contacts with wound fluid with calcium alginate by ion exchange, discharge calcium ion and form gel to wound, induced platelet activation produces hemocyte somatomedin, play the effect of hemostasis and accelerating wound healing, make the wound of bleeding profusely can be at 5-10 quick-acting haemostatic powder immediately in second.Sodium carboxymethyl cellulose in the present invention, carboxymethyl chitosan and carboxymethyl chitosan fiber energy rapid, high volume absorb the hemorrhage of wound, after sucking blood, expand and form colloid, carboxymethyl chitosan fiber and calcium alginate fibre have sterilization and on surface, form gelatinous integral body, can make equally it reach haemostatic effect.
