Abstract: A unit is provided comprising a filter assembly (11, 35, Fig. 4 not shown) and a cap and connector assembly (16, 31) which functions to substantially reduce the risk of contaminants entering the flow of material delivered to a patient from a reservoir. The cap and connector assembly (16, 31) protects the apparatus from contamination during priming. A first portion (31c) of the cap (31b) serves to close off the material flow route through the connector, but the first portion (31c) can be removed by tearing it away from a second portion (31a) at a weak area (33) thereby opening the material flow route and allowing the apparatus to be primed. As the system is primed, the second portion (31a) of the cap protects the outer wall of the connector (16) from contamination by material flow. After priming, the second portion (31a) of the cap is removed, thereby exposing the outer wall of the connector (16) for mating with a complementary connector (27). The housing (35) of the filter (Fig. 8 not shown) provides a Y-connector for a recirculating administration apparatus which prevents contamination in a recirculating administration apparatus caused by counterflow in the recirculation line. <IMAGE>
