The proximal end portion includes a tapered recess defined by a wall, a chamfer, and a seat and the surface portion includes a gripping mechanism. A conduit is positioned between the tapered recess and the generally cylindrical recess such that the conduit is in fluid communication with both the recess and the generally cylindrical recess. ## Claims ### Claim 1 An adapter for a medical receptacle having an internally threaded skirt with an outside diameter and an inside diameter, and a post within the skirt, the adapter comprising: 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, 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, the generally cylindrical recess and the tapered recess spaced apart by the length of the conduit, the length of the conduit having a diameter smaller than both the seat diameter and the generally cylindrical recess diameter. ### Claim 2 (depends on 1) The adapter of claim 1, wherein the seat is perpendicular to a longitudinal axis. ### Claim 3 (depends on 1) The adapter of claim 1, wherein an angle formed between the seat and the wall is approximately 90°. ### Claim 4 (depends on 1) The adapter of claim 1, wherein an angle formed between the seat and the wall is less than 90°. ### Claim 5 (depends on 1) The adapter of claim 1, wherein an angle formed between the seat and the chamfer is greater than approximately 90° and less than approximately 180°. ### Claim 6 (depends on 1) The adapter of claim 1, wherein the at least one thread is a plurality of threads. ### Claim 7 (depends on 6) The adapter of claim 6, wherein the plurality of threads is two threads. ### Claim 8 (depends on 1) The adapter of claim 1, wherein the gripping mechanism is at least two wings extending from the surface portion. ### Claim 9 (depends on 8) The adapter of claim 8, wherein the at least two wings are substantially parallel to a longitudinal axis. ### Claim 10 (depends on 8) The adapter of claim 8, wherein the at least two wings are angled axially at least 5° from a longitudinal axis. ### Claim 11 (depends on 1) The adapter of claim 1, wherein the gripping mechanism is a plurality of ribs. ### Claim 12 (depends on 1) The adapter of claim 1, wherein the gripping mechanism is a plurality of knurls. ### Claim 13 (depends on 1) The adapter of claim 1, wherein the surface portion further includes a collar projecting therefrom. ### Claim 14 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. ### Claim 15 (depends on 14) The method of claim 14, wherein the seat is perpendicular to a longitudinal axis of the adapter. ### Claim 16 (depends on 14) The method of claim 14, wherein the gripping mechanism is at least two wings extending from the surface portion. ### Claim 17 (depends on 14) The method of claim 14, wherein the at least one thread is a plurality of threads. ### Claim 18 (depends on 17) The method of claim 17, wherein the plurality of threads is two threads. ### Claim 19 (depends on 14) The method of claim 14, wherein the surface portion further includes a collar projecting therefrom. ### Claim 20 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.
