Medical PVA Foam

Medical PVA Foam is divided into two types: hemostatic type and trauma drainage type. The hemostatic type is composed of PVA Foam and traction wire; the trauma drainage type is composed of PVA Foam, drainage tube, connecting tube, tube clamp, medical tee and surgical film. The main component of PVA Foam is polyvinyl alcohol; the material of the traction line is PET polyester thread; the material of the drainage tube is medical silicone tube; the material of the connecting tube is medical PVC; the material of tube clamp and medical tee is ABS; the material of surgical film is medical PU film. The product is sterilized by irradiation and should be sterile.

Steps

1. Clean the wound

Check the wound, completely remove the necrotic tissue, pus, foreign body, repair the blood vessels, nerves and tendons that need to be reconstructed. If there is a fracture, it needs to be reset first.

2. Shaping

Prune the PVA Foam according to the size of the wound, or cover the wound or fill the sinus or fistula, and no dead space can be left. When the area is large, the negative pressure drainage sponge can be connected in series.

3. Fixed

The shaped negative pressure drainage sponge and the skin around the wound are sutured and fixed.

4. Clean the skin around the wound

Wash the skin around the wound with sterile saline, remove blood stains, and use 75% alcohol to completely remove complexed iodine, sebum, and dandruff to keep the skin around the wound clean and dry.

5. Seal

Cover the negative pressure drainage sponge with a surgical film. The coverage should include at least 2 to 3 cm of healthy skin on the wound edge. Paste layer by layer on the healthy skin without drainage tube to ensure the sealing effect.

There are three methods of sealing: smashing hole method, mesangial method, and wrapping method

6. Adjust negative pressure

After returning to the ward, connect the negative pressure source, adjust the negative pressure value between -125～-450mmHg (-0.017～－0.060MKP). Drainage is continued within 48 hours after operation, and intermittent drainage after 48 hours.
