ABSTRACT:
A device for the mixing and administration of intravenous fluid comprising a cylindrical vial having an open end and a closed end, an inwardly extending integral annular ring within the vial and forming part of the walls of the vial intermediate said open and closed ends. A tippable center septum seals on the annular ring. An imperforate stopper is provided in the open end of the vial. The vial is adapted to contain two liquids or a liquid and a dry material in separated state. A non-opaque drip meter having a fluid outlet at one end and a fluid inlet is provided, the inlet comprising a tubular member terminating within the drip meter whereby drops can be visually observed at the end of the tubular member through the drip meter. Extending from the drip meter is a solid or hollow elongated rigid spike having an enlarged base adjacent the drip meter, the spike terminating in a point at its other end. A filtered air inlet is positioned in proximity to the base of the spike, a passage and filter are associated with the spike or base for admitting filtered air into the vial. A fluid passage runs through the base and has one end adjacent the spike at the exterior of the base and the other end communicates with the tubular member. The spike is adapted to puncture the stopper and tip the septum whereby the contents of the vial can be mixed without contamination from the exterior and the fluid contents of the vial can flow through the fluid passage and the drip meter while filtered air passes into the vial.
