Abstract

A tubing set for a blood processing system includes a first connector, a first tube, and a second tube. The first connector is configured to connect to a separation device within the blood processing system, and has a first inlet configured to be fluidly connected to an outlet of the separation device. The first connector also has an outlet and a second inlet. The first tube fluidly connects to the outlet and fluidly connects the separation device and a blood component storage container. The second tube is fluidly connected to the second inlet and fluidly connects the separation device and a saline storage container. The second tube may include a second connector that connects to the saline storage container.

First claim

What is claimed is:

1. A tubing set for a blood processing system comprising:
a first connector configured to connect directly to a centrifuge bowl within the blood processing system, the first connector having a body with a first end and a second end, the first connector also having a first inlet located within first end and configured to be fluidly connected to an outlet of the centrifuge bowl, the first connector also having an outlet located within the second end and a second inlet located within the second end;
a first tube fluidly connected to the outlet and configured to fluidly connect the centrifuge bowl and a final blood component storage container, the final blood component storage container configured to collect a blood component to be collected; and
a second tube fluidly connected to the second inlet and configured to fluidly connect the centrifuge bowl and a saline storage container, the second tube including a second connector configured to connect to the saline storage container.

2. A tubing set according to claim 1 , wherein the second connector is a spike.

3. A tubing set according to claim 1 , wherein the tubing set includes a cap, the cap configured to cover the first inlet of the first connector when the first connector is not connected to the centrifuge bowl.

4. A tubing set according to claim 3 , wherein the cap is tethered to the first connector.

5. A tubing set according to claim 3 , wherein the cap makes a liquid-tight seal on the first connector.

6. A tubing set according to claim 3 , wherein the cap includes a rib extending from an inner surface of the cap, the rib configured to seal against an outer surface of the first connector.

7. A tube set according to claim 3 , wherein the cap includes a tab extending from a surface of a body of the cap, the tab configured to allow a user to remove the cap from the first connector when connected.

8. A tubing set according to claim 1 , wherein the second tube is tinted.

9. A tubing set according to claim 1 , wherein the second tube includes at least one marking to indicate that the second tube is configured to be connected to the saline storage container.

10. A tubing set according to claim 9 , wherein the at least one marking includes text indicating that the second tube is configured to be connected to the saline storage container.

11. A tubing set according to claim 1 , wherein the first tube includes at least one marking to indicate that the first tube is configured to be connected to the final blood component storage container.

12. A tubing set according to claim 11 , wherein the at least one marking includes dots and/or lines.

13. A tubing set according to claim 1 , wherein the first and second tubes are color coded.

14. A tubing set according to claim 1 , wherein the first tube has a first portion and second portion.

15. A tubing set according to claim 14 , wherein the second portion includes a pre-curved section, one end of the pre-curved section configured to connect to the final blood component storage container.

16. A tubing set according to claim 15 , wherein the pre-curved section is integrally formed with the second portion.

17. A tubing set according to claim 15 , wherein the pre-curved section is solvent bonded to the second portion.

18. A tubing set according to claim 14 , wherein the first tube includes a sample site located between the first portion and the second portion.

19. A tubing set according to claim 18 , wherein the sample site includes a sample site inlet fluidly connected to the first portion, a sample site outlet fluidly connected to the second portion, and a sample port.

20. A tubing set according to claim 19 , wherein the sample port includes a septum, the septum configured to seal the sample port.

21. A tubing set according to claim 20 , wherein the sample site is configured to receive a sample collection container holder.

22. A tubing set according to claim 1 , wherein the outlet includes a first fluid path fluidly connecting the first inlet and the outlet, a diameter of the first fluid path expanding toward the outlet.

23. A tubing set according to claim 1 , wherein the second inlet includes a second fluid path fluidly connecting the first inlet and the second inlet, a diameter of the second fluid path expanding toward the second inlet.

24. A tubing set according to claim 1 , wherein the final blood component storage container is a plasma container.

25. A tubing set according to claim 1 , wherein the first end has a first surface and the second end has a second surface, the first inlet located within the first surface, the outlet and second inlet located within the second surface.

26. A tubing set according to claim 1 , further comprising:
a first fluid path extending at least partially through the connector body and fluidly connecting the first inlet and the outlet; and
a second fluid path extending at least partially through the connector body and fluidly connecting the first inlet and the second inlet, the first fluid path being parallel to the second fluid path.

27. A connector for a blood processing system comprising:
a connector body defining the structure of the connector, the connector having a first end and a second end;
a first port configured to connect directly to an outlet of a centrifuge bowl of the blood processing system, the first port located within the first end;
a second port fluidly connected to the first port and located within the second end, the second port configured to be fluidly connected to a first tube, the first tube configured to fluidly connect the second port and a final blood component storage container, the final blood component storage container configured to collect a blood component to be collected; and
a third port fluidly connected to the first port and located within the second end, the third port configured to be fluidly connected to a second tube, the second tube configured to fluidly connect the third port and a saline storage container.

28. A connector according to claim 27 , further comprising;
a cap configured to cover the first port when the first port is not connected to the centrifuge bowl.

29. A connector according to claim 28 , wherein the cap is tethered to the connector body.

30. A connector according to claim 28 , wherein the cap makes a liquid-tight seal on the first connector.

31. A connector according to claim 28 , wherein the cap includes a rib extending from an inner surface of the cap, the rib configured to seal against an outer surface of the first connector.

32. A connector according to claim 28 , wherein the cap includes a tab extending from a surface of a body of the cap, the tab configured to allow a user to remove the cap from the first connector when connected.
