Luer lock adapter

A method for securing an adapter to a medical receptacle having an internally threaded skirt with an outside diameter and an inside diameter, and a post within the skirt comprising the steps of:

• (a) providing an adapter including:
• a proximal end portion having a threaded surface including at least one thread configured to threadingly engage a threaded interior of a skirt of a medical receptacle, the proximal end portion including a tapered recess defined by a wall, and a chamfer having a transition from the wall to a seat, seat having a diameter;
• a distal end portion having a surface portion including a gripping mechanism and a generally cylindrical recess having a diameter;
• and
• a conduit positioned between the tapered recess and the generally cylindrical recess such that the conduit is in fluid communication with both the tapered recess and the generally cylindrical recess and the generally cylindrical recess and the tapered recess are spaced apart by the length of the conduit, the conduit having a diameter smaller than both the seat diameter and the generally cylindrical recess diameter;
• (b) inserting a post of a medical receptacle into the tapered recess;
• and
• (c) twisting the adapter to engage the at least one thread of the adapter with an internally threaded skirt the medical receptacle.

A method for securing an adapter to a medical receptacle having an internally threaded skirt with an outside diameter, an inside diameter and an upper surface, and a post within the skirt, comprising the steps of:

• (a) providing an adapter including:
• a proximal end portion having a threaded surface including at least one thread configured to threadingly engage a threaded interior of a skirt of a medical receptacle, the proximal end portion including a tapered recess defined by a wall, and a chamfer having a transition from the wall to a seat, the seat having a diameter, the proximal end portion including a collar projecting from the threaded surface
• a distal end portion having a surface portion including a gripping mechanism and a generally cylindrical recess having a diameter, and
• a conduit positioned between the tapered recess and the generally cylindrical recess such that the conduit is in fluid communication with both the tapered recess and the generally cylindrical recess and the generally cylindrical recess and the tapered recess are spaced apart by the length of the conduit, the conduit having a diameter smaller than both the seat diameter and the generally cylindrical recess diameter;
• (b) inserting a post of a medical receptacle into the tapered recess;
• and
• (c) twisting the adapter to engage the at least one thread of the adapter with a threaded interior of a skirt of the medical receptacle until the collar contacts an upper surface of the skirt.
