ABSTRACT:
The system of this invention provides a method and apparatus for the sterile intravenous administration of dry medicine. Such a system can include standard IV set components such as a source of liquid, means to inject liquid into a human vein, means forming a passageway between the source of liquid and said injection means, a valve to control the flow of liquid through the passageway, and a cartridge-like dry medicine package adapted for use with the system. Such a package can include conduit means adapted to perforate and communicate with the passageway, means forming a cell for dry, particulate medicine with portions forming a liquid-pervious barrier to the dry medicine and an air vent with an air-pervious, liquid barrier. The perforating conduit means is in communication with the liquid-pervious barrier portion of the cell so that, upon perforation of the passageway means by the perforating conduit means below the source of liquid, the cell fills with liquid, the medicine is placed in solution in the liquid, and the medicine solution flows into the vein. Dry medicine can, for example, be administered intravenously in liquid solution in a variety of dosages and at a variety of rates without resort to a pharmacy by enclosing it in such a sterile package adapted for addition to an IV system at a patient's bedside.
