Abstract

The invention discloses a method for preparing a quick hemostatic dressing. The method comprises the following steps: 1, firstly, taking sodium carboxymethyl cellulose, carboxymethyl chitosan, polyethylene glycol and guar gum, grinding the bone of squid into powder, and evenly mixing the raw materials at the normal temperature to form a mixture A; 2, vibrating the mixture A obtained in the step 1 by a vibrating screen and then evenly pasting the mixture A on an adhesive medical tape; 3, cutting calcium alginate fiber and chitosan fiber into short fiber respectively, evenly mixing the short fiber, and punching the short fiber by a needle to form non-woven fabrics; and 4, covering the non-woven fabrics on the surface of the medical tape stuck with the mixture A, and finally forming a finished product. The quick hemostatic dressing has the advantages of low manufacturing cost, easy degradation, good hemostatic effect, and convenient use by a patient.

Description

technical field [0001] The invention relates to a method for making a rapid hemostatic dressing. Background technique [0002] Bleeding from accidental wounds in the wild, bleeding in car accidents, and bleeding from wounded soldiers on the battlefield all require a quick hemostasis method, but there is no wound dressing that can quickly stop bleeding in the current market.
