Tubing system with pump for delivering continuous fluid flow or fluid bolus to a surgical site
First Claim
1. A tubing set for use with a source of irrigating fluid and an intraoperative medical instrument having a fluid passage inlet, comprising:
- a first fluid passage section communicating with an inlet for connection to the source of fluid;
a second fluid passage section communicating with an outlet for connection to the intraoperative medical instrument;
a pump for delivering a bolus of fluid, said pump connected between said first fluid passage section and said second fluid passage section; and
a first valve located between said inlet and said outlet to the medical instrument to prevent flow in a direction toward said inlet, but permit flow in a direction toward said outlet.

Abstract
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.
