Abstract
A valve adapted for pooling blood components comprising a valve housing and a valve plug, with channels through the valve plug. By rotating the valve plug, selected ports in the valve housing may be brought into communication so that fluids may flow between the ports in communication. To facilitate transfusions of blood components, the valve may be used to pool multiple units of blood components and to resuspend masses of component particles, enabling them to be drawn out of the blood component bag. The risk of infection is decreased, and a more efficient use of the contents of the blood component bags is obtained. A method for producing a blood component pooling device is also disclosed. A containerized kit of the blood component pooling valve is provided which includes a rotary valve; a syringe adapted to be connected to the first port of the rotary valve; hoses, syringe fitting, hypodermic needle, and plastic bag needle to connect the other three ports to a capped vial of sterile saline solution, and a blood component pooling bag respectively; a sealed vial containing a sterile saline solution; a sterile blood component pooling bag; and a sterile sealed packet containing the kit elements.
