Abstract

A container for blood is provided in which blood received from a patient can be stored and processed without the necessity of being transferred to another container. For example, the blood can be centrifuged, frozen or transfused without the necessity of being transferred to another container. The container comprises a closed annular flexible container of a flexible material which is inert to blood and which is provided with at least one opening for the passage of blood into and out of the annular container. The flexible material may be enclosed in an inflexible material.

Claims

1. In combination, a centrifuge having a rotor and, disposed about said rotor in said centrifuge, an annular container for holding blood during rotation of said centrifuge, said annular container being made of a flexible material and comprising a hollow annular chamber formed by two annular side walls spaced apart a short distance and by two transverse end walls extending between and joining the edges of said annular sides thus forming said chamber, the central area of said container within the annular chamber being open such that the annular container is disposable about said rotor, and said annular container including a tube attached to the end wall of said container adjacent the open central area of the container for conveying blood into and out of said annular container.

2. The combination according to claim 1 wherein said container includes an outer portion of non-flexible material totally enclosing said flexible annular container.

3. The combination according to claim 1 wherein said outer wall is formed by the outer edges of said annular sides being bent towards one another and joined to each other.

4. An annular container for holding blood during centrifuging, said container being made of flexible material and comprising a hollow annular chamber formed by two annular side walls spaced apart a short distance and by two transverse end walls extending between and joining the edges of said annular sides thus forming said chamber, the central area of said container within the annular chamber being open such that the annular container is disposable about a centrifuge rotor, said annular container including a tube attached to the end wall of said container adjacent the open central area of the container for conveying blood into and out of said annular container, said chamber being conical such that the container is adapted to bear against a conical member in a centrifuge during centrifuging.
