ABSTRACT:
To replace the usual gravity apparatus for intravenous injection of fluid in the body, there is provided a portable casing into which the usual collapsible liquid-containing flask is placed between two separate panels, one or both of which are movable toward and away from the other. The separation of the plates is against the force of prestressed torsion springs and these springs force the plates together toward a closed position when they are released after the flask has been placed between them to apply pressure to the flask and expel the liquid from the flash through a flexible tube having a discharge terminal. An actuating extension attached to the movable plate or plates is arranged to releasably hold them in separated positions when a flash is being removed or inserted between them. A garment is provided in which this apparatus may be retained when the patient is ambulatory.
