ABSTRACT:
A medical fluid flow set comprises flexible flow tubing having a plastic "pillow" connected in-line with the flow tubing through opposed, generally parallel first and second longitudinal ports. By this invention, the plastic pillow comprises a single, blow-molded, integral piece with a third port communicating with the pillow at a point between the first and second ports. The third port tube extends laterally outwardly from the pillow and turns, typically by essentially a right angle to define an outer tube end having an axis essentially parallel to the first and second ports. A set branch line may be connected to the outer tube end. Such a pillow is manufactured by blow molding to provide an improved product over the prior art, at less cost.
