ABSTRACT:
An active gas removal system is provided to remove air or gas bubbles from an intravenous fluid prior to infusion into the patient. The system detects the level of liquid in a drip chamber and occludes a downstream valve to the patient, thereby increasing pressure in the drip chamber sufficient to open a vent valve and release gas therein.
