ABSTRACT:
A unit is provided comprising a filter assembly, a cap and connector assembly to substantially reduce the risk of contaminants entering the flow of material delivered to a patient. The cap and connector assembly portion protects an administration kit from contamination during the priming of the kit. A first portion of the cap closes off the material flow route through the connector, but can be removed by tearing it away from the second portion at a weak area, opening the flow route and allowing the administration kit to be primed. As the system is primed, the second portion of the cap protects the outer surface of the connector. After the administration set has been primed, the second portion of the cap is removed, exposing the outer walls of the connector for mating with a complementary connector. The housing includes three ports for material flow. First and second ports are adjacently positioned on one side of the housing to recirculate the material without the material passing through the filter material within the housing. The third port is located on the housing such that material flow between the third port and either the first or second port requires the material to flow through the filter material. Also provided is a Y-connector for a recirculating administration kit and a housing for a filter which prevents contamination in a recirculating administration kit caused by counterflow in the recirculation line.
