Abstract
An adapter for a medical receptacle having a skirt with an outside diameter and a threaded inside diameter, and a tapered post within the skirt, the adapter includes a proximal end portion having a threaded surface including at least one thread configured to threadingly engage the threaded inside diameter of the skirt, a distal end portion having a surface portion and a cylindrical recess, a conduit positioned between the tapered recess and the cylindrical recess such that the conduit is in fluid communication with both the tapered recess and the cylindrical recess; and a longitudinal axis. The proximal end portion includes a tapered recess defined by a wall, a chamfer, and a seat and the surface portion includes a means for gripping, which in one embodiment may be at least two wings.

An adapter for a medical receptacle having a skirt with an outside diameter and a threaded inside diameter, and a tapered post within the skirt, the adapter comprising:
- a proximal end portion having a threaded surface including at least one thread configured to threadingly engage the threaded inside diameter of the skirt, the proximal end portion including a tapered recess defined by a wall, a chamfer having a flat transition from the wall to a seat, and the seat having a diameter,
- a distal end portion having a surface portion and a cylindrical recess having a diameter;
- an elongated conduit positioned between the tapered recess and the cylindrical recess such that the conduit is in fluid communication with both the tapered recess and the cylindrical recess and the 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 cylindrical recess diameter;
- and
- a longitudinal axis;
- wherein the surface portion includes a means for gripping.
A method for securing an adapter to a medical receptacle having a skirt with an outside diameter and a threaded inside diameter, and a tapered post within a hub comprising the steps of:
- (a) providing an adapter comprising a proximal end portion having a threaded surface including at least one thread configured to threadingly engage the threaded inside diameter of the skirt, the proximal end portion including a tapered recess defined by a wall, a chamfer having a flat transition from the wall to a seat, and the seat having a diameter,
- a distal end portion having a surface portion and a cylindrical recess having a diameter;
- an elongated conduit positioned between the tapered recess and the cylindrical recess such that the conduit is in fluid communication with both the tapered recess and the cylindrical recess and the 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 cylindrical recess diameter;
- and
- a longitudinal axis;
- wherein the surface portion includes a means for gripping,
- (b) inserting the tapered post into the tapered recess;
- and
- (c) twisting the adapter to engage the at least one thread of the adapter with the threaded inside diameter of the medical receptacle.
A method for securing an adapter to a medical receptacle having a skirt with an outside diameter, a threaded inside diameter and an upper surface, and a tapered post within a hub comprising the steps of:
- (a) providing an adapter comprising a proximal end portion having a threaded surface including at least one thread configured to threadingly engage the threaded inside diameter of the skirt, the proximal end portion including a tapered recess defined by a wall, a chamfer having a flat transition from the wall to a seat, and the seat having a diameter, a distal end portion having a surface portion and a cylindrical recess having a diameter, an elongated conduit positioned between the tapered recess and the cylindrical recess such that the conduit is in fluid communication with both the tapered recess and the cylindrical recess and the 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 cylindrical recess diameter, and a longitudinal axis, wherein the surface portion includes a means for gripping and the proximal end further includes a collar projecting from the threaded surface;
- (b) inserting the tapered post into the tapered recess;
- and
- (c) twisting the adapter to engage the at least one thread of the adapter with the threaded inside diameter of the skirt until the collar contacts the upper surface of the skirt.
