Abstract

A medical connector and adapter system that includes: a male cable connector, and a female cable-receiving housing for electrically coupling with the male cable connector. The male cable connector has a keying protrusion that corresponds to a keying channel in the cable-receiving housing. The keying feature prevents the male cable connector from being installed into a cable-receiving housing that does not have a keying channel.

Claims

1. An electrical medical connector apparatus comprising:

a cable-receiving housing having an interior chamber, a semi-cylindrical surface extending into the interior chamber, two housed electrical connectors, a front end having a first aperture for receiving a male cable connector and the cable receiving housing having a keying channel extending out of the interior chamber from the front end, along a portion of the length of the interior chamber.

2. The electrical medical connector apparatus of claim 1 wherein the male cable connector further comprises a light covering portion surrounded by semi-cylindrical surface of housing unit when the male cable connector is inserted in the housing unit.

3. The electrical medical connector apparatus of claim 1 further comprising a male cable connector inserted into the first aperture of the cable-receiving housing, the male cable connector comprising two electrical conductors electrically connected to the housed electrical connectors.

4. The electrical medical connector apparatus of claim 3 wherein the male cable connector further comprises a wiping portion adapted to providing a wiping action to the housed electrical connectors.

5. The electrical medical connector apparatus of claim 3 wherein the male cable connector further comprises a semi-cylindrical channel formed in the exterior of the male cable connector, the semi-cylindrical channel adapted to slide over and surround a semi-cylindrical surface of the cable-receiving housing when the cable connector is inserted into the cable-receiving housing.

6. The electrical medical connector apparatus of claim 3 wherein the male cable connector further comprises a keying protrusion along a portion of its length corresponding to the keying channel of the cable-receiving housing.

7. The electrical medical connector apparatus of claim 3 wherein the male cable connector further comprises a conductive socket electrically connected to each of the two electrical conductors and an expandable tube surrounding each conductive socket, the expandable tubes expanding when the sockets make electrical connection with the housed electrical connectors.

8. The electrical medical connector apparatus of claim 7 wherein the male cable connector further comprises a light covering portion surrounded by semi-cylindrical surface of housing unit when the male cable connector is inserted in the housing unit.

9. An male cable connector comprising:

a shell having an interior surface and an exterior surface;

two electrical conductors electrically connected to two conductive sockets forming the interior surface of the shell;

a semi-cylindrical channel formed in the shell adapted to slide over and surround a semi-cylindrical surface of a housing unit into which the cable connector is inserted to make electrical contact between the cable connector and the housing unit; and

a keying protrusion located on the exterior of the shell.

10. The male cable connector of claim 9 further comprising a wiping portion adapted to providing a wiping action to electrical connectors of a cable-receiving housing into which the male cable connector is inserted to make electrical contact between the cable connector and the housing unit.

11. The male cable connector of claim 10 further comprising a light covering portion extending over the channel and adapted to cover a light disposed within the channel when the male cable connector is inserted in the housing unit to make electrical contact between the cable connector and the housing unit.

12. A medical connector apparatus comprising:

a cable-receiving housing and an electrical medical cable connector, the cable-receiving housing having an interior chamber, the cable-receiving housing forming a semi-cylindrical surface extending into the interior chamber, the cable-receiving housing further forming a keying channel extending out of the interior chamber from the front end of the cable-receiving housing along a portion of the length, the cable-receiving housing further comprising two housed electrical connectors therein, and a front end having an aperture for receiving a male cable connector, wherein the male cable connector comprises, two electrical conductors electrically connected to two conductive sockets within a shell of the male cable connector, wherein each of the conductive electrical sockets of the male cable connector are connected to each of the electrical conductors; and

a semi-cylindrical channel formed in the shell adapted to slide over and surround the semi-cylindrical surface of the housing unit when the cable connector is inserted to make electrical contact between the cable connector and the housing unit.

13. The electrical medical connector apparatus of claim 12 wherein the cable connector further comprises a wiping portion adapted to providing a wiping action to the housed electrical connectors.

14. The electrical medical connector apparatus of claim 12 wherein the housing unit is formed from a rigid material and the cable connector is formed from a pliable material.

15. An electrical medical connector apparatus comprising:

a cable-receiving housing and an electrical medical cable connector, the cable-receiving housing having an interior chamber, the cable-receiving housing forming a semi-cylindrical surface extending into the interior chamber, the cable-receiving housing further forming a keying channel extending of the interior chamber from the front end of the cable-receiving housing along a portion of the length, the cable-receiving housing further comprising two housed electrical connectors therein, and a front end having an aperture for receiving an electrical medical cable connector, wherein the male electrical medical cable connector comprises, two electrical conductors electrically connected to two conductive sockets within a shell of the electrical medical cable connector, wherein each of the conductive electrical sockets of the male cable connectors are connected to each of the electrical conductors;

a semi-cylindrical channel formed in the shell adapted to slide over and surround the semi-cylindrical surface of the housing unit when the cable connector is inserted to make electrical contact between the cable connector and the housing unit, and further wherein the shell has a keying protrusion adapted to slide within the keying channel of the cable-receiving housing.

16. The electrical medical connector apparatus of claim 15 wherein the cable connector further comprises a wiping portion adapted to providing a wiping action to the housed electrical connectors.

17. The electrical medical connector apparatus of claim 15 wherein the housing unit is formed from a rigid material and the cable connector is formed from a pliable material.
