It is adapted used at discharge end an intravenous feeding pump and will automatically switch over as soon dosage has been dispensed. The device comprises cylindrical chamber somewhat nature enlarged hypodermic syringe. inlet one outlet other. A piston-like separator slidably mounted on interior said chamber. mixture placed between piston pumping system pump, from being connected tube needle inserted blood vessel patient. When operated, it pushes axially cylinder thereby forcing out into reaches cylinder, seal wall broken, by means ridges projecting inwardly chamber, or cavities formed thereof. Means provided for exhausting air both when introduced its premeasured system.
