PVA SPONGE FOR SURGICAL SPONGE DRESSING

The main material of surgical sponge dressing is medical PVA sponge. PVA medical grade macroporous sponge has excellent liquid absorption function, high comfort level, high strength, and soft appearance when touched with human body, which is widely used in clinical trauma surgery

Under normal circumstances, the product can absorb more than 15 times its own weight in liquid. This kind of material is used to replace absorbent cotton and absorbent gauze in surgery, and sponge products can solve the problem of continuous replacement of absorbent cotton or absorbent gauze in clinical surgery.

Medical PVA sponge is made of polyvinyl alcohol molecular chain by cross-linking and curing through crosslinking agent, does not contain fiber or fiber head, and will not have fiber fall phenomenon in use.

The traditional hemostatic materials are generally absorbent cotton or medical gauze. Although these materials play a certain role in hemostasis and preventing wound infection, they have some disadvantages such as not obvious hemostatic effect, poor moisturizing effect, easy growth of granulation tissue into gauze mesh leading to scab adhesion, easy to lead to exogenous infection when soaked, and no promotion of wound healing.
When PVA medical blood sponge is not used, the clinical use is mostly oil gauze, which is troublesome for doctors to place and painful for patients. The biggest hidden danger is the infection caused by the yarn dropping and the wound bleeding again. The use of PVA medical sponge products greatly solves the above problems and improves the efficiency of surgery.
