Hyaluronic acid sponge for medical purposes

Action mechanism and advantages

Indications:Hemostasis, filling, repair and other functions, suitable for wound, burn and surgical wound hemostasis, repair and residual cavity filling. 

Safe and reliable:Good biocompatibility, non-animal origin, will not cause heterogenic virus infection; n Rapid hemostasis: the water absorption is more than 40 times, the bleeding site is adhered to and closed, the clotting mechanism is activated, and the hemostasis is rapid; n Prevent adhesion: form a three-dimensional porous gel layer, form a physical barrier, play a role in tissue isolation and prevent adhesion; n Repair tissue: fill the damaged cavity of soft tissue, become a growth scaffold for new growth cells, and nourish the wound, which is conducive to tissue reconstruction;   n Degradation and absorption: The degradation cycle is 2-6 weeks, sodium hyaluronate can be degraded by the body, and the final metabolites are carbon dioxide and water.

Animal effectiveness test and biocompatibility verification data

Experimental unit: PLA Navy General Hospital

The hemostatic properties and guaixing properties were verified by animal experiments, such as hemostasis of arteries and skin in miniature pigs, hemostasis of abdominal aorta in rats and hemostasis of skin in rabbits, and compared with gauze and gelatin sponge. The performance of the waterproof breathable film was measured by animal experiments on auxiliary dressings, its antibacterial performance against three kinds of easily infected bacteria was measured by antibacterial performance, and its permeability was measured by water vapor permeability. No hemolytic reaction was verified by the hemolytic performance test.
