Abstract
This invention provides a device for first mixing and then dispensing a measured volume of a drug diluted in a predetermined ratio with an intravenous feeding solution. The device is inserted between the supply container and an intravenous feeding pump. The device is contained in a transparent tube marked with indicia showing volumes therein. A close-fitting piston, preferably made of soft rubber, fits within the container and is movable therein. A rigid stem extends axially through the piston and out of the chamber and is of sufficient strength so that it can be grasped by hand for manually moving the piston within the chamber. This conduit provides a throughflow passage from the inlet to the outlet, and thence to the intravenous feeding pump. A flexible germ barrier is provided for sealing the interior wall of the container from contamination by air at all times it is in the flow system.
