SAP qui absorbe le sang
La résine fait généralement référence à un polymère organique qui a une plage de ramollissement ou de fusion après avoir été chauffé, et a tendance à s'écouler sous l'action d'une force externe lors du ramollissement, et est solide, semi-solide et parfois liquide à température ambiante. Au sens large, tout composé polymère pouvant être utilisé comme matière première pour la transformation de produits en plastique est appelé une résine.
Matériaux polymères naturels
★ Chitosan: It has appropriate biocompatibility and degradation properties, can promote platelet adhesion and thrombosis, and is terrific for excellent types of wounds.
★ Collagen: Activates clotting factors, promotes blood clotting, and is biocompatible and biodegradable to beneficial aid wound healing.
★ Cross-linked starch microspheres: can promote blood clotting, manipulate bleeding, restriction the cost of bloodborne infection, and have no immune response and allergic reaction.
★ Gelatin sponge: Through platelet aggregation, activation of coagulation factors and bodily barriers, it can obtain hemostasis and can rapidly soak up blood.
★ Cellulose material: There are many types, such as medical absorbable hemostatic gauze, hemostatic sealant, etc., which are fantastic for one-of-a-kind sorts of wounds. It can take in blood, promote platelet aggregation and thrombosis, and gather hemostasis.
Synthetic polymer materials
★ Polyurethane: It has right plasticity and mechanical properties, can promote thrombosis, and is suitable for trauma with large-scale hemorrhage.
★ Polyacrylamide: Forms a hydrogel that can take in plasma, pay interest blood, promote platelet aggregation, and is excellent for visceral hemostasis
