Abstract: Method and apparatus is disclosed relating to the use of a plasma receiving assembly including a container and closure cap adapted to permit aseptic handling, storage and shipment of blood plasma. One aspect of the method is to form the plasma receiving assembly by placing a plasma receiving container within an overwrap having a gas permeable bacterial filter such that the container and overwrap may be gas sterilized followed by mechanical sealing of the container while still in the overwrap. The method further provides for use of the overwrap to lessen the chances of contamination during handling and transfer of the blood plasma including the steps of forming the container in a rigid standardized cylindrical form and limiting the volume of plasma placed in each container so that the plasma may be frozen and removed automatically.

Abstract: An improved measuring chamber for use in an intravenous feeding set is defined by a rigid transparent plastic chamber and includes an injection site formed in a side wall of the chamber. With the injection site in this position, the tendency of dust to collect on the injection site is significantly reduced. Moreover, adding medication to the measuring chamber is easier because the attendant need not reach so high. Finally, if the injection site is located below the liquid level of parenteral fluid in the chamber, homogeneous mixing of the parenteral fluid and the medication added thereto can be accomplished by simply pumping the plunger of the hypodermic syringe used to add the medication to the chamber.
