1. A method of producing a blood component pooling device for pooling platelets or cryoprecipitates, the method comprising:

  • (a) providing a valve comprising;

    a valve housing having a bore extending partly therethrough that is bounded by a surface of revolution that is defined by a side wall of the housing, said housing having four ports opening into its bore through the side wall of the housing; and

    a valve plug rotatably mounted in the bore of said housing, and having two non-intersecting channels extending therethrough, said channels being arranged to that by rotation of the valve plug a first port, with a syringe fitting, may be brought into exclusive communication with each of the other ports so that fluids may flow only between the first port and the port in communication therewith;

    (b) connecting a syringe to the first port;

    (c) connecting a first hose to a second port, said first hose being connected at its second end to a terminal hypodermic needle;

    (d) connecting a second hose to a third port said second hose being connectable at its second end to a blood component pooling bag; and

    (e) connecting a third hose to a fourth port, said third hose being connected at its second end to a plastic bag needle insertable into a blood component bag containing platelets or cryoprecipitates.
