ABSTRACT:
In a parenteral solution administration set, the porous hydrophilic filter member which can control the liquid level and prevent the passage of gas downwardly through the set can be located adjacent the lower end of the drip chamber to control flow out of the lower end and to be submerged in liquid held in the drip chamber during operation thereof. Significant advantages are obtained. Particularly, the set becomes conveniently usable with parenteral solution pumps. Also the drip chamber may contain an elongated member projecting inwardly of the lower end of the chamber and carrying indicia along its length to indicate liquid volume in the chamber as a function of liquid level.
