VENTED DRIP CHAMBER FOR USE WITH A SYRINGE ABSTRACT OF THE INVENTION A vented drip chamber,threadably engageable with a fluid filled hypodermic syringe, comprises an adapter having dual passageways. A first passageway allows fluid communica- tion between the syringe and the drip chamber while the second passageway provides an air vent from outside the drip chamber to the syringe. The second passageway further comprises a cannula which extends into the fluid upon attachment of the drip chamber with the syringe. A ball valve which is disposed in the second passageway allows air to flow into the syringe to replace the dispensed fluid, but does not allow fluid to flow from the syringe through the second passageway.
