    3. Prove forward direction rinse which make sure dressing material and drainage tube freely and increase the area and effectiveness of drainage.

    We hope to show more clearly rinse effect distinction of different design product by our operating demonstration.

    Connect the dressing, Y-connector, straight connector and negative pressure source together. Keep negative pressure among -125mmHg~-450mmHg(-0.017Mpa ~ -0.060Mpa). after surgical operation continue suction for 48 hours, then use the method of interrupted suction, start 5 minutes and stop 2 minutes.
