Abstract

A connection device has a male connector and a female connector. The female connector will only accommodate the dedicated male connector, thereby prohibiting a misconnection with the wrong male connector. In certain embodiments, a member prohibits male connectors, other than a dedicated male connector, from being inserted into the female connector. In certain other embodiments, a post prohibits male connectors, other than a dedicated male connector including a slot, from being inserted into the female connector. In still certain other embodiments, a series of prongs in the male connector and corresponding grooves in the female connector ensure the proper connection. Once the male connector is inserted and secured within the female connector, a fluid-tight seal is formed between the male connector and the female connector.

First claim

What is claimed is:

1. A connection device comprising:
a male connector comprising a body, a distal end, a proximal end, a projection, and a threaded locking hub, the projection having an opening located at the distal end of the body, the opening in fluid communication with a fluid passageway located within the body, and the projection having a slot; and
a female connector comprising a body, a distal end, and a proximal end, a fluid passageway located within the body, the female connector further comprising a post perpendicular to the fluid passageway within the body of the female connector, the post engaging the slot of the projection during insertion of the male connector into the female connector, wherein the threaded locking hub is configured to threadingly engage the female connector to secure the male and female connectors together.

2. The connection device of claim 1 , wherein the threaded locking hub extends around the female connector when the projection of the male connector is inserted into the female connector.

3. The connection device of claim 1 , wherein the projection comprises a frustoconical external surface.

4. The connection device of claim 3 , wherein the body of the female connector comprises a conical inner surface configured to sealingly mate with the frustoconical external surface of the male connector.

5. The connection device of claim 1 , wherein the slot is positioned on an external surface of the projection, and intermediate to a proximal end and a distal end, of the projection.

6. The connection device of claim 5 , wherein, in a first position, the body of the male connector is partially inserted into the body of the female connector such that the post is positioned in a first end portion of the slot, and in a second position, the body of the male and female connectors are rotated relative to each other such that the body of the male connector is further inserted into the body of the female connector, and the post is positioned in a second end portion of the slot.

7. The connection device of claim 1 , wherein the slot of the male connector is a rotational cut-out around an exterior surface of the projection of the male connector.

8. The connection device of claim 7 , wherein the rotational cut-out is configured such that as the male connector is partially inserted into the female connector, the post engages an end of the slot, and then the male connector is rotated such that the post of the female connector moves up the slot until the male connector is fully inserted.

9. The connection device of claim 1 , wherein the post of the female connector is cylindrically shaped, such that the post engages the slot.

10. The connection device of claim 1 , wherein the post of the female connector is positioned within the fluid passageway such that the post engages the slot of the male connector upon partial insertion of the male connector into the female connector.

11. The connection device of claim 1 , wherein the male and female connectors are Luer connectors.

12. A connection device comprising:
a male body having a first end and a second end, a threaded locking hub, and an inner surface defining a cavity that extends from the second end into the male body, and a projection extending from the male body within the cavity, the projection comprising an outer surface having a slot, wherein a fluid passage of the male body extends through the projection; and
a female body having a first end and a second end, a cavity extending from the second end into the female body, and a post extending from the female body radially inward into the cavity, wherein a fluid passage of the female body comprises the cavity;
wherein the post is configured to extend into the slot to permit advancement of the projection into the cavity of the female body, and, when the projection is positioned within the cavity of the female body, the threaded locking hub extends around the female body to secure the male and female bodies together.

13. The connection device of claim 12 , wherein a post longitudinal axis is transverse to a fluid passage longitudinal axis of the female body.

14. The connection device of claim 12 , wherein the projection comprises an outer surface that tapers toward the second end, and the cavity of the female body comprises an inner surface that tapers toward the first end.

15. The connection device of claim 12 , wherein the projection comprises a frustoconical external surface.

16. The connection device of claim 12 , wherein the slot is positioned on an external surface of the projection such that a length of the slot is intermediate to a proximal end and a distal end of the projection.

17. The connection device of claim 16 , wherein, in a first position, the male body is partially inserted into the female body such that the post is positioned in a first end portion of the slot, and in a second position, the male and female bodies are rotated relative to each other such that the male body is further inserted into the female body, and the post is positioned in a second end portion of the slot.

18. The connection device of claim 12 , wherein the slot is a rotational cut-out that extends around the projection.

19. The connection device of claim 18 , wherein the rotational cut-out is configured such that as the male body is partially inserted into the female body, the post engages an end of the slot, and then the male body is rotated such that the post advances along the slot until the male connector is fully inserted.

20. The connection device of claim 12 , wherein the post is positioned within the fluid passage of the female body such that the post engages the slot upon partial insertion of the male body into the female body.
