PROCESS AND APPARATUS FOR COMPOUNDING HYPERALIMENTATION SOLUTIONS SOLUTIONS ABSTRACT OF THE DISCLOSURE A process and apparatus for mixing at least two paren- teral solutions, sterilizing the resulting mixture, and transferring the sterilized mixture into an extensible, plastic receiving bag. The apparatus includes a mixing chamber into which the solutions can be delivered, a bac- terial organism retentive filter for sterilizing the mixture of the solutions received from the chamber, such a receiving bag, tubing for transferring each of the solutions to the chamber, and second tubing for transferring the sterilized mixture from the filter to the bag. All are combined and then sterilized as a unit. In one embodiment of the in- vention, the bag is placed in a vacuum chamber to facilitate transfer of the mixture through the apparatus and the mixing chamber has a baffle or system of baffles for creating turbulence in the solutions while they are being mixed. The diameter and length of each tubing leading into the chamber form a solution holding container is pre-selected with respect to the viscosity of the solution in that holding container, so that both solutions reach the chamber at the same time or in a selected order and are mixed in an equal or pre-selected proportion therein.
