Locking connector assembly
First Claim
1. A shrouded cannula for connecting a fluid supply line to an infusion line, the infusion line having a septum mounted thereon and an external skirt extending outwardly and radially therefrom, said shrouded cannula comprising:
- a substantially cylindrical shroud, said shroud having a longitudinal axis, an inlet portion connectable to said supply line, and a receiving portion having an inner surface and an outer surface, said inner surface defining a recess to receive said infusion line;
at least one lateral slot formed circumferentially in said shroud, said slot extending from said outer surface to said inner surface and through said shroud;
a cannula completely surrounded by said shroud and attached thereto to be located in said recess and positioned to pierce said septum on said infusion line to establish fluid communication with said supply line; and
a locking mechanism selectively insertable through said slot, and held therein for abutting said skirt of said infusion line, when said infusion line is located in said recess to prevent said infusion line from exiting said recess.

Abstract
A locking connector assembly is provided for use with Y-sites and/or other infusion line fittings. The connector assembly includes a shrouded connector including a cannula. A retention clip having a pair of prongs is provided. When the shrouded connector is installed on a Y-site or other fitting, and the retention clip is in the locking configuration, the prongs of the retention clip extend through a pair of opposing through-slots in the shroud to cooperatively engage a surface irregularity on the Y-site or other fitting thereby preventing disengagement of the shrouded connector from the Y-site or other fitting.

11. A device for connecting a fluid supply tube in fluid communication with a fluid infusion tube, the infusion tube having an external protrusion and a pierceable septum across an inlet of the infusion tube, the device comprising:
-
a cannula having a first end and a second end, said first end of said cannula being attachable in fluid communication with said supply line and said second end of said cannula being positioned to pierce said septum and establish fluid communication between said supply tube and said infusion tube; a shroud having a first end and a second end with a recess formed therebetween, said first end of said shroud being attached to said first end of said cannula to completely surround said cannula and to position said cannula in said recess, said second end of said shroud being open to receive said inlet of said infusion tube in said recess as said cannula pierces said septum, and said shroud being formed with at least one slot circumferentially formed therethrough; and a retention clip formed with a prong, said prong being partially insertable through said slot in said shroud to abut said protrusion on said infusion tube and position said prong between said slot in said shroud and said protrusion of said infusion tube to hold said cannula in said septum. - View Dependent Claims (12, 13, 14, 15)

16. An IV fluid tube connection assembly, said assembly comprising:
-
a Y-site connector having a primary input, a secondary input and an output; a primary supply line connected to said primary input of said Y-site; an infusion line connected to said output of said Y-site; a seal attached to said secondary input for sealing said secondary input of said Y-site, an external skirt extending outwardly and radially from said secondary input; a secondary supply line; a substantially cylindrical shroud connected to said secondary supply line, said shroud having a longitudinal axis, an inlet portion connected to said secondary supply line, a receiving portion having an inner surface and an outer surface, said inner surface defining a recess sized to receive said secondary input of said Y-site; at least one pair of lateral slots circumferentially formed in said shroud, each said slot extending from said outer surface and through said shroud to said inner surface of said shroud to allow access to said Y-site through said shroud when said secondary input of said Y-site is in said recess; a cannula for piercing said seal, said cannula being completely surrounded by said shroud and attached thereto to be located in said recess, said cannula establishing a fluid passageway to said secondary supply line through said seal when said secondary input of said Y-site is in said recess; and a locking mechanism selectively insertable through said pair of slots and held therein for abutting said skirt when said secondary input is located in said recess to prevent said secondary input from exiting said recess. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
