Abstract

A blood bag cup, which is designed as a double cup with two individual cups with two separate chambers, one for accommodating the withdrawal and inflation bag and one for accommodating the satellite bag. The respective chamber for the satellite bags is preferably jointed. Advantages are an extremely high separation efficiency factor with maximum plasma yield with pure plasma and more than 50% time savings based on the doubled design of the double-chambered double cup.

Claims

1. A blood bag double cup assembly for separating blood components contained in bags, comprising:

first and second interconnected single cups;

each of said single cups comprising two separate chambers connected to and adjacent to each other, the first of said chambers adapted for receiving collection and inflatable bags and the second of said chambers adapted for receiving satellite bags, said first and second chambers being open at the top to allow insertion of the respective bags into the chambers from above;

each of the second chambers being formed as a flap pivotally mounted lo its single cup via a hinge such that said flap is pivotable about an axis relative to the first chamber of its single cup while connected to such first chamber, the flap having a cutout in an upper portion thereof facing its respective first chamber and a retaining portion below the cutout in the lower portion of the flap adapted to hold a satellite bag when inserted in the second chamber;

the first chamber being positioned adjacent to each other and the second chambers being positioned away from each other outside of the first chambers such that said chambers are arranged in the following sequence side by side;

the second chamber of the first single cup, the first chamber of the first single cup, the first chamber of the second single cup, the second chamber of the second single cup;

the first and the second cup with their respective first and second chambers are located next to each other as mirror images.

2. The cup assembly of claim 1, further comprising a pivotable tube guide wing located between the adjacent collection/inflation bag chambers and which is adapted to guide connection tubes into vertical alignment.

3. The cup assembly of claim 2, wherein the interconnected single cups are mirror images of one another.

4. The cup assembly of claim 3, wherein the interconnected single cups are attached to each other by a handle.

5. The cup assembly of claim 1, wherein the interconnected single cups are mirror images of one another.

6. The cup assembly of claim 5, wherein the interconnected single cups are attached to each other by a handle.

7. The cup assembly of claim 1, wherein the interconnected single cups are attached to each other by a handle.

8. The cup assembly of claim 2, wherein the interconnected single cups are attached to each other by a handle.

9. The cup assembly of claim 3, wherein the interconnected single cups are attached to each other by a handle.
