Claim 21:
22. A system for providing liquid access within an internal portion of a patient, the system comprising:
a syringe comprising a barrel having an internal cavity and an elongate plunger configured for sealed longitudinal movement within the cavity, the syringe having a distal end comprising a male luer taper;
a hub comprising a distal portion and a proximal portion, the proximal portion comprising a first interior surface comprising a female luer taper configured to sealingly mate with the male luer taper, the first interior surface intersecting with an end wall;
an elongate tube having a lumen and extending from the distal end of the hub; and
a proximally-extending projection within the proximal portion of the hub along a distal portion of the female luer taper, the projection having a central orifice, a distal end, a proximal end, a maximum diameter, and a minimum diameter;
wherein:
the central orifice is configured to communicate with the lumen of the elongate tube;
the minimum diameter is at the proximal end of the projection,
the maximum diameter is at the distal end of the projection,
the projection further comprising a frustoconical outer surface extending between the proximal end and the distal end;
a length of the projection is less than a length of the female luer taper; and
the proximally-extending projection comprises an axial length that is less than a diameter of the first interior surface at a distal end of the first interior surface where the first interior surface intersects with the end wall.
