A fluid gas removal drip chamber for use for parenteral administration of fluids is disclosed. The drip chamber has a hydrophobic barrier which extends into the interior of the drip chamber. The hydrophobic barrier preferably comprises at least a portion of a three-dimensional surface. In one embodiment, an inlet port allows fluid to enter the drip chamber from the top so that the fluid falls through an air space formed in the top of the drip chamber. By shaping the inlet port so that droplets of fluid are formed, a health care professional can monitor the fluid drip rate. In another embodiment, the hydrophobic barrier is configured so that little or no air space exists at the top of the drip chamber. The drip chamber includes means for venting air that is separated from the fluid within the chamber and, at the same time, preventing air from entering the chamber through the venting means. For certain applications, the drip chamber is provided with a hydrophilic filter for filtering the fluid prior to exiting the drip chamber.
