Abstract
An apparatus and method for effectively eliminating the risk of introducing air bubbles into a fluid delivery system such as to administer parenteral fluids to a patient. The apparatus comprises a baffle positioned within a drip chamber for deflecting fluid expelled from a fluid resistor in order to eliminate turbulence and the formation of micro-bubbles during rapid filling or flushing of the fluid delivery system. The drip chamber also comprises a filter membrane positioned across the outlet of the drip chamber. The filter membrane is attached to a filter carrier assembly which enables the filter membrane to be momentarily displaced so that air bubbles trapped beneath the filter membrane may escape.
