INTRAOPERATIVE APPLICATION OF DISPOSABLE PULSE IRRIGATOR

The advantage of Pulse Lavage Disposable applied to debridement is that it focuses on removing contamination from the wound and hidden in the wound

　　It is the key to prevent postoperative wound infection.

　　The postoperative infection rate has a lot to do with the tissue debris remaining at the surgical site. The role of wound irrigation is to:

　　① Wash away the blood and debris to facilitate observation and debridement;

　　② flush out the blood clots, loose tissues and debris hidden in the interstitial spaces and crypts;

　　③ Make the tissue show its original color to help identify whether it is alive or not;

　　④ Reduce the amount of bacteria, so that the wound can withstand the residual bacteria and is not easy to form an infection.

　　The traditional method of irrigating the surgical site is cumbersome, and it is easy to introduce bacteria. In addition, due to the limited liquid flow rate, the flushing angle cannot be controlled, so the flushing effect is not ideal, and some dead corners are not easy to flush. The principle of the pulse flushing method is to press the water out with high-pressure gas, and turn it into a pulsed water flow through a pulse generator. The pulsed water flow has a pressurization period and a decompression period, which can loosen foreign objects and pollutants and are easy to remove. Simultaneous flushing and simultaneous suction can realize the timely back suction of waste liquid and avoid the spread of infection.
