Abstract

An esophageal probe comprising, a disposable housing comprising an elongated sleeve defining a cavity, and a proximal connector. The probe has a permanent monitoring device comprising an elongated stem receivable in the sleeve cavity with a distal end of the stem located adjacent a distal end of the sleeve when the stem is fully inserted into the sleeve cavity. The monitoring device monitors a body function of a patient from a location adjacent a distal end of the stem, and has a proximal connector. The connector of the monitoring device is releasably attached to the connector of the housing when the stem is fully inserted into the sleeve cavity.

Claims

1. An esophageal probe, comprising:

a disposable housing comprising an elongated sleeve defining a cavity having a proximal end, a distal end, and a proximal opening communicating with the cavity, said housing having a sufficient length to extend from the outside of a patient'"'"'s body into the esophagus of the patient;

a permanent monitoring device having an elongated stem removably receivable through said opening into said sleeve cavity, said stem having a proximal end, a distal end, and means for monitoring a body function of a patient from within the sleeve;

means for releasably attaching said monitoring device to said housing with said stem received in the sleeve cavity, said attaching means comprising a first connector adjacent the proximal end of the monitoring device and a second connector adjacent the proximal end of the housing;

means establishing electrical connection between the first and second connectors when the first and second connectors are attached together;

a pair of spaced electrodes on an outer surface of the sleeve; and

means for electrically connecting the electrodes to the electrical establishing means of the connectors.

2. The probe of claim 1 wherein the monitoring means comprises a temperature sensor.

3. The probe of claim 2 wherein the distal end of the stem is located adjacent the distal end of the sleeve when the monitoring device is attached to the housing, and in which the sensor is located adjacent the distal end of the stem.

4. The probe of claim 1 wherein the monitoring means comprises a vibration detection device.

5. The probe of claim 4 wherein the vibration detection device comprises a microphone.

6. The probe of claim 4 wherein the distal end of the stem is located adjacent the distal end of the sleeve when the housing is attached to the monitoring device, and in which the vibration detection device is located adjacent the distal end of the stem.

7. The probe of claim 1 wherein the stem comprises an elongated tube.

8. The probe of claim 1 wherein the distal end of the stem is located adjacent the distal end of the sleeve when the housing is attached to the monitoring device.

9. The probe of claim 1 including means for releasably securing the housing connector to the monitoring device connector when the stem is fully inserted into the sleeve.

10. The probe of claim 1 including means for releasably locking the monitoring device connector to the housing connector when the stem is fully inserted into the sleeve.

11. The probe of claim 1 wherein the electrical establishing means comprises a plurality of female conducting sockets on one of said connectors and a plurality of male conducting posts on the other of said connectors, said posts being aligned with and receivable in the associated sockets.

12. The probe of claim 1 wherein the sleeve includes a pair of spaced conducting plates on an outer surface of the sleeve extending from the electrodes to a proximal end of the sleeve, and in which the first connector includes a pair of contacts which contact said plates when the first and second connectors are attached together.

13. The probe of claim 12 wherein said contacts comprise a pair of conducting posts on the first connector.
