Abstract

A device for supporting and displaying interrelated medical components, such as cardiopulmonary bypass circuit components. The device includes a rigid or flexible chassis having openings therein for receiving the components. A plurality of retainers, such as straps, hooks, or tabs, are provided adjacent the openings for releasably securing the components therein. The chassis may be formed of a thin, flexible polymer sheet having tabs cut therein and adapted to be bent out of the plane of the sheet for securely retaining the various components. The pre-arrangement of the components in close proximity greatly simplifies the task of setting up a particular medical circuit, and reduces the potential for error. For cardiopulmonary bypass circuits, the support device enables the tubing lengths to be reduced, thus reducing the prime volume of the circuit. The chassis is provided with apertures for mounting on rods in the operating room, which rods may extend from the operating table. Handles are also provided on the chassis for conveniently transporting the components or circuit. The compact nature of the chassis and components thereon simplifies and reduces the cost of packaging and shipping. In addition, disposal of a used circuit is facilitated by the provision of a clean bag around the entire system. A pumpless cardioplegia delivery system is also provided.

Claims

1. A support device for an extracorporeal blood circuit in which a blood reservoir, an oxygenator, a blood filter and a plurality of tubing sections are in fluid communication with each other, said support device comprising:

a chassis having a planar surface;

means for removably mounting and supporting the blood reservoir, oxygenator and blood filter in close proximity on the chassis; and

,

a series of channels formed in the chassis, said channels sized to receive and protect the tubing sections, wherein the channels are defined by the absence of material in the chassis and parallel to the planer surface of the chassis.

2. The support device of claim 1, when the support means comprises a plurality of openings in the chassis.

3. The support device of claim 2, wherein the chassis is formed of a polymer sheet and the openings are cut therein.

4. The support device of claim 3, further including a plurality of tabs formed by cuts in the polymer sheet, the tabs being bendable from the plane of the polymer sheet and being adapted to releasably retain the extracorporeal blood circuit components.

5. The support device of claim 4, wherein one or more of the cuts are directed away from the openings so that any tears that may occur between the tabs and the polymer sheet are propagated away from the openings.

6. The support device of claim 2, wherein the chassis comprises a generally planar body and is reversible so that the blood reservoir, oxygenator, and blood filter may be supported and displayed in the openings from either side of the planar body.

7. The support device of claim 1, wherein the chassis is rigid.

8. The support device of claim 1, wherein the chassis is planar.

9. The support device of claim 1, wherein the chassis is flexible.

10. The support device of claim 1, wherein the chassis is generally planar.

11. The support device of claim 1, wherein the chassis is formed of a polymer.

12. The support device of claim 11, wherein the polymer is non-brittle and non-abrasive.

13. The support device of claim 1 wherein the support means comprises a plurality of retainers.

14. The support device of claim 13, wherein the retainers comprise straps.

15. The support device of claim 13, wherein the retainers comprise hooks.

16. The support device of claim 13, wherein the retainers comprise hook and loop fasteners.

17. The support device of claim 13, wherein the retainers comprise tabs formed in the chassis.

18. The support device of claim 17, wherein the tabs are flexible and may be bent away from the chassis.

19. The support device of claim 18, wherein the chassis comprises a planar body, and wherein the tabs are formed by cuts in the planar body that are bendable from the plane of the planar body about living hinges and are adapted to releasably retain the extracorporeal blood circuit components.

20. The support device of claim 1, wherein the support means comprises adhesive bonds.

21. The support device of claim 1, wherein the extracorporeal blood circuit components are integrally formed into the chassis.

22. The support device of claim 1, wherein the chassis comprises a wire grid and the extracorporeal blood circuit components are supported by the wire grid using suitable retainers.

23. The support device of claim 1 wherein the support means and the channels are arranged in sufficiently close proximity that the prime volume for the entire extracorporeal blood circuit is less than 1500 cubic centimeters.

24. The support device of claim 23 wherein the support means and the channels are arranged in sufficiently close proximity that the prime volume for the entire extracorporeal blood circuit is less than 1000 cubic centimeters.
