Abstract
A cardiotomy suction tube system comprises a main line, a first flexible branch line in fluid communication with the main line, a second flexible branch line in selective fluid communication with the main line, and a rigid branch line in selective fluid communication with the main line. A valve mechanism selectively places either the second flexible branch line or the rigid line in fluid communication with the main line. The first flexible branch line may be provided with a weighted suction tip which gravitates to a low point in an operative field. The second flexible branch line may be provided with a weighted suction tip which gravitates to a low point in an operative field.

A cardiotomy suction tube system consisting essentially of:
- a main suction line;
- a first branch suction line in direct and continuous fluid communication with the main suction line;
- a second branch suction line in selective fluid communication with the main suction line;
- a third branch suction line in selective fluid communication with the main suction line;
- and
- a three-way valve mechanism to selectively place either the second branch suction line or the third branch suction line in fluid communication with the main suction line, the second branch suction line and the third branch suction line each being connected to the three-way valve mechanism at their respective proximal ends;
- wherein the first branch suction line and the second branch suction line each have a distal tip configured to draw fluid from an operative field and the third branch suction line has a distal end configured to draw fluid from the operative field.
