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 vertically mounting the blood reservoir and blood oxygenator. Trays may be releasably attached to the carrier to serve as containers for coiled tubing used in the support circuit.
Claims36
A pack assembly for use in an extracorporeal blood circuit, comprising:
- (a) a carrier adapted to mount a blood reservoir and a blood oxygenator, said carrier including first and second carrier mounting elements for securely mounting said blood reservoir and said blood oxygenator;
- (b) a blood reservoir releasably secured to the carrier, said blood reservoir including a reservoir mounting element cooperable with one of said carrier mounting elements for securely mounting said blood reservoir to said carrier;
- (c) a blood oxygenator releasably secured to the carrier, said blood oxygenator including an oxygenator mounting element cooperable with one of said carrier mounting elements for securely mounting said blood oxygenator to said carrier;
- and
- (d) at least one tray releasably attached to at least one of the carrier, the blood reservoir and the blood oxygenator, said at least one tray providing a protective packaging for said blood reservoir and said blood oxygenator and a containment area for tubing components.

A pack assembly for use in an extracorporeal blood circuit, comprising:
- (a) a carrier adapted to vertically mount a blood reservoir and a blood oxygenator, comprising:
- (i) an attachment plate;
- and
- (ii) a substantially vertical mounting plate associated with the attachment plate, the mounting plate being adapted for mounting the carrier on a vertical support;
- (b) a blood reservoir releasably attached to the attachment plate;
- and
- (c) a blood oxygenator releasably attached to the attachment plate;
- wherein the attachment plate of said carrier is adapted to independently and separately mount said blood reservoir and said blood oxygenator such that one of said blood reservoir and said blood oxygenator may be removed from said carrier without removing another of said blood reservoir and said blood oxygenator.

A pack assembly for use in forming an extracorporeal blood circuit, comprising:
- (a) a carrier adapted to vertically mount a blood reservoir and a blood oxygenator, comprising:
- (i) an attachment plate;
- and
- (ii) a substantially vertical mounting plate associated with the substantially horizontal attachment plate, the mounting plate being adapted for mounting the carrier on a mast;
- (b) a blood reservoir releasably attached to the attachment plate;
- (c) a blood oxygenator releasably attached to the attachment plate;
- and
- (d) two trays releasably attached to the carrier, the blood reservoir or the blood oxygenator;
- (e) a prime line comprising a priming tube and at least one bag spike attached to the reservoir, at least a portion of the prime line being disposed within one of the trays;
- (f) an A-V loop comprising a venous line and an arterial line, the venous line attached to the reservoir and the arterial line attached to the oxygenator, at least a portion of the A-V loop being disposed within one of the trays;
- (g) a suction line attached to the reservoir, at least a portion of the suction line being disposed within one of the trays;
- and
- (h) a pump loop comprising a pump inlet line attached to the reservoir, a pump header attached to the pump inlet line, and a pump outlet line attached to the pump header and the oxygenator, the pump header and at least a portion of the pump inlet line and pump outlet lines being disposed within one of the trays;
- wherein said item (a)-(h) are preassembled to define said pack assembly prior to use in an extracorporeal blood circuit.
