Abstract

A self-contained pack assembly includes all of the disposable components of an extracorporeal support circuit for cardiac bypass surgery. The pack assembly comprises a blood reservoir, a blood oxygenator, and a carrier for mounting the blood reservoir and blood oxygenator. One or more trays may be releasably attached to the carrier to serve as storage containers for coiled tubing used in the support circuit. Pre-made connections can also be formed between the tubing and the blood reservoir and blood and oxygenator as may be desired.

Claims

1. A pack assembly for use in an extracorporeal blood circuit, comprising:

(a) a carrier adapted to mount at least one blood handling apparatus;

(b) at least one blood handling apparatus releasably attached to the carrier, said blood handling apparatus comprising at least one of a blood reservoir and a blood oxygenator;

wherein said carrier includes a handle mechanism for grasping by a user during lifting and repositioning of the pack assembly.

2. A pack assembly according to claim 1, further comprising:

at least one tray releasably attached to at least one of the carrier and the blood handling apparatus.

3. A pack assembly according to claim 2, wherein said at least one tray includes at least one partition for subdividing an interior area of said at least one tray into at least two sections.

4. A pack assembly according to claim 3, further comprising a cover extending over said at least one tray.

5. A pack assembly according to claim 4, wherein said cover is removably disposed so as to uncover only one of the at least two sections.

6. A pack assembly according to claim 3, wherein said at least one tray includes a plurality of partition guides and said at least one partition is removably disposed within one of said plurality of partition guides.

7. A pack assembly according to claim 1, further comprising:

a mounting bracket releasably engaged with the carrier.

8. A pack assembly according to claim 7, wherein said carrier includes mounting flanges and said mounting bracket includes a receiving channel for receiving said mounting flanges therein.

9. A pack assembly according to claim 8, further comprising:

a barrier pouch enclosing the carrier and the at least one blood handling apparatus, said barrier pouch being deformable so as to allow the engagement of said mounting flanges in said receiving channel of said mounting bracket without tearing said barrier pouch.

10. A pack assembly according to claim 9, wherein said barrier pouch includes means for removal from said pack assembly.

11. A pack assembly according to claim 8, wherein said mounting flanges include tapered edges and said mounting bracket includes a correspondingly tapered said receiving channel.

12. A pack assembly according to claim 2, wherein said at least one blood handling apparatus comprises two blood handling apparatuses, said two blood handling apparatuses including said blood reservoir and said blood oxygenator.

13. A pack assembly according to claim 12, further comprising a retainer bar for retaining said blood reservoir and said blood oxygenator in a mounted position.

14. A pack assembly according to claim 13, wherein said retainer bar is releasably engaged with said carrier.

15. A pack assembly according to claim 14, wherein said retainer bar includes at least one outwardly projecting tab for releasing said retainer bar from said carrier.

16. A pack assembly according to claim 12, further comprising a stabilizer clip for securing said blood reservoir.

17. A pack assembly for use in an extracorporeal blood circuit, comprising:

(a) a first support structure adapted to mount at least one blood handling apparatus;

(b) at least one blood handling apparatus releasably attached to said first support structure, said blood handling apparatus comprising at least one of a blood reservoir and a blood oxygenator; and

(c) at least one second support structure including an enclosure for sealingly enclosing at least one tubing line prior to use.

18. The pack assembly according to claim 17, wherein said at least one second support structure includes a tray and a cover disposed over an opening of the tray.

19. The pack assembly according to claim 18, wherein said cover defines a plurality of separately openable compartments within the tray.

20. The pack assembly according to claim 17, wherein said at least one second support structure is movable relative to said first support structure so as to fold inward.

21. A pack assembly for use in an extracorporeal blood circuit, comprising:

(a) a carrier adapted to mount a blood reservior and a blood oxygenator, comprising;

(i) an attachment plate; and

(ii) a carrier base including a mounting plate, the mounting plate being adapted for mounting the carrier on a vertical support;

(b) a blood reservior releasably attached to the attachment plate; and

(c) a blood oxygenator releasably attached to the attachment plate;

wherein said carrier includes a handle mechanism for grasping by a user during lifting and repositioning of the pack assembly.

22. The pack assembly according to claim 21, wherein said attachment plate includes upper and lower receiving channels, said blood reservoir and said blood oxygenator being slidingly received in a respective said receiving channel on the attachment plate.

23. The pack assembly according to claim 22, wherein said blood reservior includes an adapter for cooperating with the respective receiving channel of the attachment plate.

24. The pack assembly according to claim 21, wherein said attachment plate includes an upper cylindrical boss for receiving said blood reservoir and a lower cylindrical socket for receiving said blood oxygenator.

25. The pack assembly according to claim 21, further comprising at least one removable tray.
