Abstract

The subject disclosure is directed to female connectors which can be employed in a quick connect/disconnect system used in medical devices to provide a non-permanent electrical and mechanical engagement with a male connector. The female connectors include, inter alia, a connector body that has an outer periphery and an aperture extending therethrough. The connector body has a flexible, non-conductive portion and a conductive portion which is at least partially exposed in the aperture and on the outer periphery of the connector body. The connector body is constructed such that when a male connector is inserted into the aperture of the connector body, the flexible, non-conductive part and the conductive part of the connecter body cooperate to allow for expansion of the aperture, creating contact pressure between the conductive part of the connector body and the male connector.

Claims

1. A female connector for positioning in an insulated adapter housing, to receive a male connector, the female connector comprising:

a connector body having an outer periphery and defining a through aperture having an inner periphery, the connector body including;

a) a flexible, non-conductive portion and;

b) a conductive portion, which at least partially defines the inner periphery of the aperture and the outer periphery of the connector body, the conductive portion being adapted and configured to expand radially outwardly upon insertion of the male connecter therethrough, the connector body being constructed such that when the male connector is inserted through the aperture of the connector body, the flexible, non-conductive portion and the conductive portion of the connecter body cooperate to allow for radially outward expansion of the aperture, resulting in radially inwardly directed contact pressure between the conductive portion of the inner periphery of the connector body and an outer periphery of the male connector.

2. A female connector as recited in claim 1, wherein the connector body is a cuboid.

3. A female connector as recited in claim 1, wherein the aperture has a circular cross-section when viewed in a plane extending perpendicularly through its central axis.

4. A female connector as recited in claim 1, wherein the conductive portion of the connector body is more rigid than the non-conductive portion of the connector body.

5. A female connector as recited in claim 1, wherein the conductive portion of the connector body includes two or more conductive segments.

7. A female connector as recited in claim 5, wherein the conductive portion of the connector body includes interlocking segments which define the aperture and are adapted and configured to move radially with respect to one another.

8. A female connector as recited in claim 1, wherein at least a portion of the aperture is defined by the flexible, non-conductive portion of the connector body.

9. A female connector as recited in claim 1, wherein the conductive portion of the connector body defines an inner diametrical surface of the aperture.

10. A female connector as recited in claim 9, wherein the inner diametrical surface defined by the conductive portion of the connector body includes a plurality of circumferentially spaced, axially extending grooves.

11. A female connector as recited in claim 1, wherein the conductive portion of the connector body is made from a material selected from the group consisting of titanium, 316L stainless steel or MP35N, and combinations thereof.

12. A female connector as recited in claim 1, wherein the conductive portion of the connector body is made from a nonmagnetic, nickel-cobalt-chromium-molybdenum alloy.

13. A female connector as recited in claim 1, wherein the non-conductive portion of the connector body is made from silicon.

14. A female connector as recited in claim 1, wherein the connector body is made using an over-molding process.

15. A female connector as recited in claim 1, wherein the connector body is made using an injection molding process.

6. (canceled)

16. A female connector for positioning in an insulated adapter housing to receive a male connector having an outer diameter, the female connector comprising:

a connector body having an outer periphery and defining a through aperture having an inner periphery, the connector body including a flexible, non-conductive portion and a conductive portion which at least partially defines the inner periphery of the aperture and the outer periphery of the connector body, the conductive portion being adapted and configured to expand radially outwardly upon insertion of the male connector therethrough, the connector body being constructed such that when the outer diameter of the male connector is larger than the inner diameter of the aperture, the flexible, non-conductive part and conductive part of the connecter body cooperate to allow for expansion of the aperture and receipt of the male connector and create contact pressure between the conductive portion of the connector body and the male connector.

20. A female connector as recited in claim 16, wherein the conductive portion of the connector body includes two or more conductive segments.

17-19. -19. (canceled)

21-30. -30. (canceled)

31. An electrical adapter for receiving at least one male connector, the adapter comprising:

a) a housing defining at least one receptacle for receiving the male connector; and

b) at least one female connector disposed within the receptacle defined by the housing, the female connector including a connector body having an outer periphery and defining a through aperture having an inner periphery, the connector body including a flexible, non-conductive portion and a conductive portion which at least partially defines the inner periphery of the aperture and the outer periphery of the connector body, the conductive portion being adapted and configured to expand radially outwardly upon insertion of the male connecter therethrough, the connector body being constructed such that when the male connector is inserted into the aperture of the connector body, the flexible, non-conductive portion and the conductive portion of the connecter body cooperate to allow for radially outward expansion of the aperture, resulting in radially inwardly directed contact pressure between the conductive portion of the inner periphery of the connector body and an outer periphery of the male connector.

32. An electrical adapter as recited in claim 31, comprising a plurality of female connectors coaxially positioned within the receptacle and axially spaced apart, each female connector being adapted for electrical communication with surface electrodes provided on the male connector.

33. An electrical adapter as recited in claim 31, wherein the housing is made substantially from electrically non-conductive material.
