System and method for mixing parenteral nutrition solutions

摘要

An apparatus and method for mixing parenteral nutrition solutions from additives in a plurality of vials containing the additives, in which a vented spike is inserted through a disposable rack and into the stoppered end of each vial, with the vials secured on the rack. The rack is engaged on a stand through a quick release fitting, and maintains the vials in a vertical orientation with the labels clearly visible. A dedicated syringe is connected with each vial in aligned relationship therewith through a unique two-way valve which is mounted to a manifold. In one form of the invention, the valve is attached directly on the manifold to reduce dead space volume and consequently reduce residual fluid in the system between purges. A flushing system is attached to one end of the manifold to flush any residual fluids into the final container at the end of a transfer process. The other end of the manifold may be attached in tandem with a further manifold in a further apparatus containing additional vials for admixing even further additives.
