1. A luer lock connection device comprising:

  • a male luer connector member having a central tubular portion outwardly circumscribed by a generally tubular sheath portion and having an open end facing in a first axial direction;

    a female luer connector member operatively interconnectable with said male luer connector and having a hollow tubular portion coaxially insertable into said sheath portion to coaxially receive said central tubular portion of said male luer connector member;

    cooperating thread means on said male and female luer connector members for releasably holding them in their operatively interconnected orientation; and

    means associated with said male and female luer connector members and responsive to their operative interconnection for forming within said sheath portion a sterilant fluid-receiving chamber having;

    an inner annular portion coaxially disposed between the outer side surface of said central tubular portion and the inner side surface of said central tubular portion and the inner side surface of said hollow tubular portion of said female luer connector member, said inner annular portion having an annular first end and an annular second end spaced apart therefrom in said first axial direction, andan outer annular portion coaxially disposed between the outer side surface of said hollow tubular portion of said female luer connector member and the inner side surface of said sheath portion, said outer annular portion having an annular first end, and an annular second end spaced apart therefrom in said first axial direction, said first ends of said inner and outer annular portions communicating with one another; and

    seal means, responsive to the operative interconnection of said male and female luer connector members, for forming annular resilient seals around said second ends of said inner and outer annular portions of said sterilant fluid-receiving chamber.
