Abstract: A coupling and system for collecting blood or other biological fluids are described. The system includes first and second containers and a coupling for joining the containers. The coupling holds the containers together in two different longitudinal positions both positions preventing contamination. In a first position, the containers are held so that there is no flow between the containers. In a second position, the containers are held so that flow of blood is permitted between the containers.
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.
