Abstract

A blood sampling system for obtaining blood samples from a fluid flow path is disclosed. The sampling system includes a container that can be isolated from the remainder of a blood processing set and allows for collection of a sample either before or after the blood donation.

Claims

1. A blood sampling system comprising:

a container for receiving a biological fluid comprising a pair of oppositely facing walls joined together to define an interior chamber, an inlet port communicating with said interior chamber and an outlet port communicating with said interior chamber opposite said inlet port;

a tubing segment defining a fluid flow path, said tubing segment communicating with said outlet port and extending substantially into said interior chamber; and

a sample vial holder attached to said outlet port and in flow communication with said flow path of said tubing segment.

2. The system of claim 1 wherein said holder comprises a first end, a second open end and a body portion defining an interior pocket between said first and second ends, wherein said first end is attached to said outlet port to establish flow communication between said holder and said container interior.

3. The system of claim 2 wherein said holder comprises a piercing member disposed within said interior pocket.

4. The system of claim 1 wherein said holder comprises a generally cylindrical body portion.

5. The system of claim 2 wherein said holder comprises at least one pair of oppositely facing flexible walls comprising said body portion and an openable and closable interior pocket.

6. The system of claim 5 wherein said holder comprises pinching tabs between said flexible walls.

7. The system of claim 3 wherein said holder comprises positioning prongs disposed within the interior pocket of said body portion on either side of said piercing member.

8. The system of claim 6 wherein said holder comprises pinching tabs near said second open end.

9. A disposable blood processing set comprising:

a first container adapted for receiving blood directly from a donor;

a vein access device;

a first tubing segment defining a first flow path between said container and said access device;

a second container adapted for receiving blood directly from a donor, said second container including an interior chamber, an inlet port, an outlet port and a tubing communicating with said outlet port and extending substantially into the interior chamber;

a second tubing segment defining an openable flow path between said second container and said access device.

10. The disposable processing set of claim 9 wherein said second tubing segment is joined to said first tubing segment at a junction.

11. The disposable processing set of claim 9 comprising an openable barrier disposed within said second tubing segment.

12. The disposable processing set of claim 9 comprising a holder connected to said outlet port and communicating with said second container interior chamber.

13. The disposable processing set of claim 9 wherein said second container comprises a generally circular fluid receiving chamber.
