摘要
The cap and connector assembly (31, 16) portion of the unit protects an administration kit (11, 13, 15) from contamination during the priming of the kit. A first portion of the cap (31) serves to close off the material flow route through the connector (16), but the first portion can be removed by tearing it away from the second portion at a weak area (33), thereby opening the material flow route and allowing the administration kit to be primed. As the system is primed, the second portion of the cap (31) protects the outer surface of the connector (16) from contamination by material flow. After the administration set has been primed, the second portion of the cap (31) is removed, thereby exposing the outer walls of the connector (16) for mating with a complementary connector (27). The housing of the filter assembly (36) of the unit includes three ports for material flow. First and second ports (36a, 36b) are adjacently positioned on one side of the housing (36) so as to cooperate to recirculate the material without the material passing through the filter material within the housing. The third port (36c) is located on the housing (36) such that material flow between the third port (36c) and either the first or second port (36a, b) requires the material to flow through the filter material (47).
