ABSTRACT:
An improved heat sterilizable blood bag system adapted for containing and mixing of different materials originally placed in separate but potentially communicating compartments. The improvement comprises of having a smaller squeezable compartment for one material attached to and capable of communicating with a larger compartment for the other material. The material in the smaller compartment is separated from the interior of the larger compartment by means of an externally manipulatable closure means which, when opened, permits mixture of the contents in the first compartment and contents of the second compartment when the smaller compartment is repeatedly squeezed.
