Vacuum Sealing Drainage (VSD) is an innovation treatment for surgical trauma. At present, it is the most advanced treatment for many kinds of acute trauma and chronic skin ulcer.
Particular pva material with peculiar bridge-link structure ensures VAC be circulated well.
Nowadays, we have three type of NPWT kits with different sponges ,which are PVA, PU and PVA combining PU(white and black) NPWT dressings.
VAC ensures thoroughly clearance of dead tissue, exudates of edema and metabolite, which blocks body tissue from reabsorption of toxic products.
Unique softness and plasticity makes deep and irregular wound be isolated, which provides good healing environment and accelerates repair of the wound.
1-2mm open microstructure
Excellent hydrophilicity and wound compatibility
Viscous exudate fluid and necrotic tissue can pass through
900 Pa compressive strength
Greatly shorten the wound healing cycle
