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.
