Abstract
An oximeter sensor can be used with multiple oximeter systems. The oximeter sensor includes a first light-emitting diode, a second light-emitting diode and a photodetector. Electrical connections to the anode and the cathode of each light-emitting diode and electrical connections to the terminals of the photodetector are provided on a connector. An interconnector is interposed between the connector of the oximeter sensor and a connector in communication with an oximeter system. The interconnector has interconnection wiring selected to electrically connect the sensor connector and the system connector in a manner to configure the light-emitting diodes in a configuration compatible with the oximeter system. In particular, a first interconnector configures the light-emitting diodes in a common anode arrangement. A second interconnector configures the light-emitting diodes in a back-to-back (anode to cathode, cathode to anode) configuration. Either interconnector may be in the form of a shell having two connectors. Alternatively, either interconnector may be in the form of a flexible cable with connectors at each end.
