Tubing system for delivering fluid to a surgical site
First Claim
1. A tubing set for use with a peristaltic pump for providing pressurized fluid from a source to a surgical instrument, comprising:
- a first section of tubing having a fitting for connection to a source of fluid;
a second section of tubing being formed of a flexible material and being sized and adapted for placement in a peristaltic-type pump said second section of tubing connected to said first section of tubing;
a third section of tubing connected to said section of tubing, said third section of tubing having a fitting for connection to a surgical instrument; and
a by-pass section of tubing connecting said first section of tubing and said third section of tubing, and further in which said by-pass section has a pressure relief valve that opens upon reaching a threshold pressure.

Abstract
A tubing set and method for use with a system for providing pressurized fluid from a fluid source to a surgical site. The system includes a fluid source, a length of flexible tubing having one end connected to the fluid source and another end connected to a surgical instrument, and a peristaltic type pump into which a middle portion of flexible tubing is positioned so that the peristaltic type pump can pump fluid from the source to the surgical instrument by bearing on the exterior of the tubing. The improved tubing set also includes a by-pass section of tubing connected between the tubing inlet and the tubing outlet in parallel with the middle portion of the flexible tubing. The by-pass section provides pressure relief to the system so that pressure in the tubing will not build up distally of the location of the peristaltic pump.

2. An improved system for providing fluid from a fluid source to a surgical site, the system including a fluid source having a fluid outlet, a surgical instrument having a fluid inlet, a roller type pump, and a length of flexible tubing having a tubing inlet connected to the outlet of the fluid source and a tubing outlet connected to the inlet of the surgical instrument, the length of tubing having at least one section between the tubing inlet and the tubing outlet formed of a compressible material, the compressible section located in said roller type pump so that fluid can be pumped from the fluid source to said surgical instrument by actuation of the pump, the improvement comprising:
a by-pass section of tubing connected between the tubing inlet and the tubing outlet in parallel with the compressible section. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11)

12. An improved system for providing fluid from a fluid source to a surgical site, the system including a fluid source having a fluid outlet, a surgical instrument having a fluid inlet, a roller type pump, and a length of flexible tubing having a tubing inlet connected to the outlet of the fluid source and a tubing outlet connected to the inlet of the surgical instrument, the length of tubing having at least one section between the tubing inlet and the tubing outlet formed of a compressible material, the compressible section located in said roller type pump so that fluid can be pumped from the fluid source to said surgical instrument by actuation of the pump, the improvement comprising:
-
a by-pass section of tubing connected between the tubing inlet and the tubing outlet in parallel with the compressible section, and a pressure valve located in said by-pass section, said pressure valve having a predetermined pressure at which said valve opens to allow fluid to recirculate from said tubing outlet to said tubing inlet. - View Dependent Claims (13)

14. A method for providing a fluid to a surgical site comprising the steps of:
-
attaching an outlet of a fluid source to an inlet of a tubing set; attaching an outlet of said tubing set to an inlet of a surgical instrument; positioning a compressible section of said tubing set in a peristaltic type pump; positioning a by-pass section of said tubing set outside said peristaltic pump, a first end of said by-pass section connected to and communicating with said inlet of said tubing set and a second end of said by-pass section connected to and communicating with said outlet of said tubing set and in parallel with said compressible section; and operating said pump to supply fluid from said fluid source to said surgical instrument. - View Dependent Claims (16, 17)

15. The method of claim in which said method further comprises the step of:
permitting fluid to recirculate in said by-pass section in a direction from said second end to said first end with a predetermined resistance to flow.
