ABSTRACT:
A pharmaceutical mixing container for storing a liquid having at least two factions which tend to separate during storage. A housing has an inner volume and is closed at one end by a septum arrangement and at another end by a slidable sealing member. A magnetizable mixing member is located within the housing and contacts the liquid faction of the pharmaceutical contained within the housing. An external magnet produces a magnetic field which extends within the inner volume and interacts with the mixing element. By manually translating the magnet along the axis of the housing, the mixing member is forcibly moved through the liquid causing turbulent waves which provide thorough admixing for the pharmaceutical constituents. By controlling the pace of movement of the magnet, thorough admixing is provided without causing mechanical damage to delicate constituents, such as crystalline factions found in NPH type insulin.
