Abstract

A system for collecting blood including first and second containers and coupling for joining the containers together, the coupling adapted to hold the bags locking the containers together in two different locked positions both positions preventing contamination and one of said locked positions permitting flow of blood between containers.

Claims

1. A blood collection system comprising a first container for collecting blood, a second container for receiving blood from said first container, a coupling having a female coupling portion containing a first valve and a male coupling portion containing a second valve, said coupling connected to said first and second containers respectively, said coupling holding said first and second containers together in a first locked position with the valves thereof closed preventing flow of blood between one container and another while preventing contamination of the blood passageway between the containers and when the containers are moved relatively closer together to a second locked position and held in place causing the opening of the valves for the both containers to permit the flow of blood between the containers,

wherein relative rotation between the female coupling portion and the male coupling portion does not provide relative axial movement therebetween.

2. A blood collection system comprising a first container for collecting blood, a second container for receiving blood from said first container, a coupling having a female coupling portion containing a first valve and a male coupling portion containing a second valve, said coupling connected to said first and second containers respectively, said coupling holding said first and second containers together in a first locked position with the valves thereof closed preventing flow of blood between one container and another while preventing contamination of the blood passageway between the containers and when the containers are moved relatively closer together to a second locked position and held in place causing the opening of the valves for the both containers to permit the flow of blood between the containers, and in which said coupling includes a first stop and a second stop, and a moveable member to engage said first and second stops to lock said connector in said first and second positions.

3. The system according to claim 2 in which said first and second stops are positioned on the male coupling portion of said coupling.

4. The system according to claim 3 in which each of said stops comprises a groove positioned on said male coupling portion and wherein male coupling portion is locked in place by said movable member which is supported by said female coupling portion.

5. A system for collecting blood and transferring same for reinfusion or other purposes comprising a first container, a second container, a third container, said second and third containers each coupled to a said first container by a coupling means, each said coupling means including means for locking said second or third container in a first position while maintaining a contamination free pathway between said second or third container and said first container, and means for locking said second or third container in a second position while maintaining a contamination free pathway between said second or third container and said first container, valve means associated with said coupling means between said first and second containers and between said first and third containers, said valve means being opened between said first and second container and said first and third containers by said coupling means when said coupling means are locked in said second position,

wherein relative rotation of said containers coupled by each said coupling means does not provide relative axial movement therebetween.

6. A container for collecting samples, said container comprising an integrally connected female coupling member having a passageway containing a valve assembly with a valve in a normally closed position and connected to the female coupling member a male coupling member;

said female coupling member adapted to receive said male coupling member having a passageway containing a valve assembly with a valve in a normally closed position, wherein the female coupling member and the male coupling member provide a contamination free pathway between opposing ends of a coupling formed thereby;

said male member having a first locking groove that cooperates with the female member to lock the male member and the female member together in a first position wherein both valves remain closed to seal the passageway;

said male member having a second locking groove that cooperates with the female member to lock the male member and the female member together in a second position wherein the opposing ends of the coupling are closer together and both valves are open, thereby opening the passageway between opposing ends of the coupling.

7. A container for collecting samples, said container comprising an integrally connected male coupling member having a passageway containing a valve assembly with a valve in a normally closed position;

said male coupling member adapted to receive a female coupling member having a passageway containing a valve assembly with a valve in a normally closed position, wherein the female coupling member and the male coupling member provide a contamination free pathway between opposing ends of a coupling formed thereby;

said male member having a first locking groove that cooperates with the female member to lock the male member and the female member together in a first position wherein both valves remain closed to seal the passageway;

said male member having a second locking groove that cooperates with the female member to lock the male member and the female member together in a second position wherein the opposing ends of the coupling are closer together and both valves are open, thereby opening passageway is open between opposing ends of the coupling.
