Biological fluid cassette and tubing set
First Claim
1. A blood salvage assembly mountable on a chassis having a peristaltic pump and first, second, and third plungers located thereon and a chassis protrusion protruding therefrom, the assembly comprising:
- an approximately Y-shaped frame having a central leg portion, first and second arm portions, and a notched region between the first and second arm portions, the frame being configured to be selectively mountable on the chassis so that the central leg lies adjacent the plungers and the chassis protrusion extends through the notched region;
a main conduit connected to the frame and extending from the leg portion toward the first arm portion, the main conduit having a loop port in an area of the first arm portion;
a first tubing segment;
second tubing segment;
a third tubing segment;
a first port in the frame, the first port connecting the first tubing segment to the main conduit, and being configured to hold the first tubing segment over the first plunger when the frame is mounted on the chassis and the protrusion extends through the notched region;
a second port in the frame, the second port connecting the second tubing segment to the main conduit, and being configured to hold the second tubing segment over the second plunger when the frame is mounted on the chassis and the protrusion extends through the notched region;
a third port in the frame, the third port connecting the third tubing segment to the main conduit, and being configured to hold the third tubing segment over the third plunger when the frame is mounted on the chassis and the protrusion extends through the notched region;
a centrifuge bowl having a stator, the stator having a first port and a second port; and
a fourth tubing segment having a first end connected to the loop port and a second end connected to the first centrifuge bowl stator port, the fourth tubing segment being secured at an intermediate portion thereof to the second arm thereby forming a loop between the first and second arms for engaging the peristaltic pump when the protrusion extends through the notched region.

Abstract
An apparatus for managing and controlling fluid flow through a plurality of fluid conduits includes a chassis, a plurality of conduit occluders mounted in the chassis, each occluder for association with at least one of the plurality of fluid conduits and each being selectively actuatable between an open position permitting fluid flow through a respective fluid conduit and a closed position obstructing conduit fluid flow. A single actuator is mounted in the chassis, the actuator for adjusting the plurality of occluders between the open and closed positions. A roller cage is also mounted in the chassis for mechanically interconnecting the actuator to the plurality of conduit occluders so that the single actuator is mechanically capable of maintaining one of the plurality occluders in the closed position while maintaining another of the plurality of occluders in the open position.
