1. For use in association with a reservoir of sterile fluid, disposable initially sterile apparatus for sequential sterile administrtion of fluid to a plurality of recipient sites, comprising:

  • conduit means operatively engageable with the reservoir to provide a flow path for fluid from the reservoir to a distribtuion manifold;

    a filter assembly in fluid communication with the reservoir and said distribution manifold, whereby fluid from the reservoir is filtered prior to distribution;

    said filter assembly providing filtration of particulates above about 0.22 microns in diameter and allowing for flow rates of at least about 25 millimeters/minute;

    a distribution manifold, said distribution manifold having a passage therethrough, said conduit means being in fluid communication with an end of said passage;

    a plurality of capped outlet ports in fluid communication with said passage at spaced locations therein;

    respective valves operatively associated with said outlet ports; and

    cap members removably operatively associated with said outlet ports to initially maintain said outlet ports in sterile condition;

    said valves having selectable operative positions wherein sterile fluid may selectively be directed through said central passage, blocked from movement through said central passage, or directed through the outlet port associated with the valve means, whereby said outlet ports may be used sequentially without adversely affecting the sterility of the unused outlet ports; and

    means for conducting fluid from a selected port to a recipient site.
