DETAILED DESCRIPTION The present invention involves a connector that is configured to attach both disposable and durable sensors to instruments that are responsive to signals from the sensors or to cables from the instruments.
To ensure proper operation, the connector is designed to prevent incorrect attachment of the probe to the connector.
Additionally, the connector allows for easy connection and release, yet prevents accidental disconnection.
Advantageously, the connector does not add significant noise to the system, and can be coated inside with RF shielding material.
Additional, the connector and sensor tab are not sharp and do not contain protrusions that might hurt or scratch the patient.
More specifically, the present invention involves a probe connector for use in both invasive and non-invasive measurements.
Examples of sensors are disclosed in FIGS.

5,782,757, entitled Low Noise Optical Probes, filed on the same day as the present application, which application is incorporated by reference herein.
The connector of the present invention couples the probe to a monitor or processor to analyze the signals from the probe.
Once a sensor is inserted into the connector, the sensor is locked in place and the sensor tab (connection portion of the sensor) is shielded from electromagnetic interference.
Depressing release buttons provides easy removal of the sensor from the connector.
The connector has male and female portions.
The female portion forms a receptacle that shields the electrical connection from fluids in the surrounding environment.
One aspect of the present invention involves a connector having a case defining a shroud, the case having a passageway configured to accept a sensor plug.
at least one release mechanism has an engagement wedge configured such that when depressed, the engagement wedge unlocks the sensor plug from the case.
An electrical connector secured within the case has contacts and is positioned such that the sensor plug, when inserted into the case, engages the contacts of the electrical connector
