Abstract

A container for housing body fluids, preferably blood in its component form. The container comprises a body defined by flexible walls having an interior for housing the body fluid. Additionally, a means for allowing selective fluid flow allows the blood components to be expressed from one chamber of the container into another to separate and separately house the blood components. The present invention also provides a method for separating blood into its components and individually storing same.

Claims

1. A container for housing blood products comprising:

an integral body defined by flexible walls defining at least a first, a second and a third chamber, the chambers linearly arranged in a horizontal row with the first chamber adjoining the second chamber and the second chamber adjoining the third chamber, each chamber having a linear exterior edge wherein the linear exterior edge of the first chamber adjoins the linear exterior edge of the second chamber and the linear exterior edge of the second chamber adjoins the linear exterior edge of the third chamber forming a linear side and further wherein a connection site and an exterior port are located on each of the exterior edges; and

means for allowing selective fluid communication between a first chamber and a second chamber and between a second chamber and a third chamber.

2. The container of claim 1 wherein the means for allowing selective fluid communication is a frangible access port.

3. The container of claim 1 wherein the body is constructed from plastic.

4. The container of claim 1 wherein the body includes apertures for securing the body on blood processing equipment.

5. The container of claim 1 wherein the body includes a flexible edge between each chamber constructed so that the chambers can be folded upon each other at the chamber edge.

6. The container of claim 1 further comprising a means for labeling the container wherein each chamber bears similar indicia.

7. The container of claim 6 wherein said means for labeling is a bar code.

8. The container of claim 1 wherein one of the chambers further comprises a wall member for defining at least one channel in fluid communication with the chamber.

9. The container of claim 8 wherein the channel is located in a portion of the container that includes a label on one of the flexible walls that defines the portion.

10. The container of claim 9 wherein the label is a bar code.

11. The container of claim 9 wherein the label is a peelable sticker.

12. A container for housing blood comprising:

an integral body defining at least two interior chambers for housing blood, each chamber having an exterior edge formed along one side of each of the chambers forming a continuous edge of the body and a common edge wherein the chambers are joined at the common edge and further wherein each of the at least two interior chambers includes a connection site and an exterior port located on the exterior edge;

a port located through the common edge of the at least two chambers, the port including a frangible member in the port that upon breakage allows fluid flow from one of the at least two chambers of the body to another one of the at least two chambers; and

a tube allowing blood to be received in one of the at least two chambers.

13. The container of claim 12 wherein the body is constructed from plastic.

14. The container of claim 12 wherein the body is constructed from a polyvinyl chloride-containing material.

15. The container of claim 12 wherein the body includes three chambers.
