Embodiment 1

[0014] Embodiment 1: the preparation of alginate cotton ball

[0015] 25 mass % of alginate fiber and 75 mass % of absorbent cotton fiber were used to prepare alginate cotton balls through opening, carding, sliver making, ball making and the like. It is used for tooth extraction to stop bleeding, and the pressure to stop bleeding only takes 6 minutes, which is better than cotton balls.

Embodiment 2

[0016] Embodiment 2: the preparation of alginate cotton ball

[0017] Alginate fiber 50% by mass, absorbent cotton fiber 50% by mass, and alginate cotton balls were prepared through opening, carding, sliver making, ball making and the like. It is used for tooth extraction to stop bleeding, and the pressure to stop bleeding only takes 3 minutes, which is better than cotton balls.

Embodiment 3

[0018] Embodiment 3: the preparation of alginate cotton ball

[0019] Alginate fiber 75% by mass, absorbent cotton fiber 25% by mass, and alginate cotton balls were prepared through opening, carding, sliver making, ball making and the like. For tooth extraction hemostasis surgery, the compression hemostasis time only takes 90 seconds, which is better than cotton balls.

Abstract

The invention discloses an alginate cotton ball. The alginate cotton ball is prepared from the production technologies that degreasing cotton fiber and alginate fiber are mixed, and opening, carding, strip manufacturing and ball manufacturing are performed. The medical dressing combining absorbent ball usability and alginate dressing functionality is obtained, and is particularly applicable to tooth extraction hemostasis.

Description

technical field [0001] The invention relates to a medical dressing, in particular to an alginate cotton ball for tooth extraction and hemostasis. Background technique [0002] The alginate dressing made of alginate fiber has the characteristics of high water absorption, easy gelation, and the release of calcium / zinc ions to promote blood coagulation, so it has the effects of rapid hemostasis, protection of nerve endings, pain relief, anti-adhesion, and promotion of wound healing , is an excellent modern new dressing, which is being paid more and more attention and popularized. [0003] At present, the most convenient and most commonly used method for tooth extraction hemostasis is to use cotton balls made of absorbent cotton fibers to stop bleeding. Patients need to compress for more than 40 minutes to effectively stop bleeding, which takes a long time and causes intense pain. A small number of patients with thrombocytopenia use gelatin sponge dressings for hemostasis after...
