DUO CONNECTOR PATIENT CABLE
First Claim
1. In a patient monitoring system having a sensor configured to transmit at least two wavelengths of optical radiation into a tissue site and detect the radiation after attenuation by pulsatile blood flowing within the tissue site, a patient monitor configured to process a signal responsive to the detected radiation and generate at least one parameter indicative of a patient physical condition, a patient cable for interconnecting the sensor and patient monitor comprising:
- a monitor connector configured to mate with a corresponding connector in a patient monitor;
a sensor connector configured to mate with either of two types of sensor connectors; and
a cable interconnecting the monitor connector and the sensor connector so as to transmit drive signals originating from the monitor to the sensor and to transmit sensor signals originating from the sensor to the monitor.

Abstract
A patient cable has a duo sensor connector having a first socket section and a second socket section. The first socket section is configured to removably attach a two-wavelength sensor. The second socket section in conjunction with the first socket section is configured to removably attach a multiple wavelength sensor in lieu of the two-wavelength sensor. A circuit housed in the duo sensor connector converts emitter array drive signals adapted for the multiple wavelength sensor into back-to-back emitter drive signals adapted for the two-wavelength sensor when attached.
