Abstract
A drip chamber for use in the intravenous administration of liquids formed of a generally vertically disposed, hollow chamber provided with inlet means and outlet means, with the chamber being adapted to maintain a liquid level of the intravenous liquid to be administered, and a hydrophilic filter element disposed in the drip chamber between the inlet means and outlet means. The hydrophilic filter element is constantly wetted with the liquid in the drip chamber to permit the passage of liquid through the filter element while simultaneously blocking air. The drip chamber of this invention can also be provided with a hydrophobic filter element to facilitate the elimination of air from the drip chamber.
