Tubing system with pump for delivering continuous fluid flow or fluid bolus to a surgical site

摘要

A tubing set for connecting a source of irrigating fluid to an intraoperative surgical instrument having a fluid delivery passage therein. The tubing set includes a first section having an inlet for connection to the source of irrigating fluid, a second section having an outlet for connection to the intraoperative medical instrument, and a pump connected between the first section and the second section. A valve is located between the inlet and the outlet and restricts flow so that flow is in a direction from the inlet toward the outlet. The tubing set can deliver a continuous flow or trickle of fluid from the source of irrigating fluid to the medical instrument and can deliver a bolus of fluid to the surgical instrument upon operation of the pump.
