  • Patent number: 8315683
    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.

  • Patent number: 8255027
    Abstract: A physiological sensor has emitters configured to transmit optical radiation having multiple wavelengths in response to corresponding drive currents. A thermal mass is disposed proximate the emitters so as to stabilize a bulk temperature for the emitters. A temperature sensor is thermally coupled to the thermal mass. The temperature sensor provides a temperature sensor output responsive to the bulk temperature so that the wavelengths are determinable as a function of the drive currents and the bulk temperature.

  • Publication number: 20100217103
    Abstract: An ear sensor provides a sensor body having a base, legs extending from the base and an optical housing disposed at ends of the legs opposite the base. An optical assembly is disposed in the housing. The sensor body is flexed so as to position the housing over a concha site. The sensor body is unflexed so as to attach the housing to the concha site and position the optical assembly to illuminate the concha site. The optical assembly is configured to transmit optical radiation into concha site tissue and receive the optical radiation after attenuation by pulsatile blood flow within the tissue.

  • Patent number: 7647083
    Abstract: A physiological sensor has intensity compensation introduced along an optical path from emission to detection so as to compensate for unequal tissue attenuation as a function of wavelength. The sensor has emitters configured to transmit optical radiation having multiple wavelengths into a tissue site. At least one detector is capable of receiving the optical radiation after tissue attenuation. An equalization is capable of compensating optical radiation intensity so as to account for differences in tissue attenuation across at least a portion of the multiple wavelengths.

  • Patent number: 7563110
    Abstract: A sensor interconnect assembly has a circuit substrate. An emitter portion of the substrate is adapted to mount emitters. A detector portion of the substrate is adapted to mount a detector. A cable portion of the substrate is adapted to connect a sensor cable. A first group of conductors are disposed on the substrate electrically interconnecting the emitter portion and the cable portion. A second group of conductors are disposed on the substrate electrically interconnecting the detector portion and the cable portion. A decoupling portion of the substrate disposed proximate the cable portion substantially mechanically isolating the cable portion from both the emitter portion and the detector portion so that sensor cable stiffness is not translated to the emitters or the detector.

  • Publication number: 20080242958
    Abstract: A multiple wavelength optical sensor has an emitter configured to radiate light having a plurality of wavelengths into a tissue site. The emitter comprises a plurality of LEDs configured in an array and connected within an electrical grid. A detector is configured to receive the light after absorption by pulsatile blood flow within the tissue site. The detector generates a sensor signal capable of being processed by a patient monitor so as to derive oxygen saturation, carboxyhemoglobin, methemoglobin and total hemoglobin.
