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 buoyant member is located within the housing and floats within the liquid faction of the pharmaceutical contained within the housing. By manually translating and rotating the housing, the buoyant member is forcibly moved along the liquid surface causing gentle turbulent waves which provide thorough admixing for the pharmaceutical constituents without causing mechanical damage to delicate constituents, such as crystalline factions found in NPH type insulin.
Claims10
A pharmaceutical mixing container for storing a liquid with a miscible component, said container comprising:
- a housing having a first end, a second end and a wall structure defining an inner volume;
- a closure member at said first end providing a first fluid seal;
- means for providing a second fluid seal so that said inner volume is closed;
- and
- a buoyant hollow member located within said inner volume, said buoyant member having a specific gravity less than that of the liquid to be contained so that the liquid can be gently mixed by imparting motion to said housing.
