    摘要: A pulse oximeter sensor may include reusable and disposable portions, and may include a connector adapted to electrically communicate with a physiological measurement instrument. Instrument port is in communication with the connector and provides communication with a sensor memory capable of storing sensor data, such as, for example, calibration data, emitter specifications, manufacturing data, and the like.

    摘要: A method and an apparatus for separating a composite signal into a plurality of signals is described. A signal processor receives a composite signal and separates a composite signal in to separate output signals. Feedback from one or more of the output signals is provided to a configuration module that configures the signal processor to improve a quality of the output signals. In one embodiment, the signal processor separates the composite signal by applying a first demodulation signal to the composite signal to generate a first output signal. In one embodiment, the signal processor also applies a second demodulation signal to the composite signal to generate a second output signal. In one embodiment, a phase and/or amplitude of the first demodulation signal and a phase and/or amplitude of the second demodulation signal are selected to reduce crosstalk. In one embodiment, the composite signal is obtained from a detector in a system for measuring one or more blood constituents.

    摘要: A sensor has a connector adapted to electrically communicate with a physiological measurement instrument. A breakable conductor incorporated by the sensor transitions from a continuity state to a discontinuity state as the result of sensor wear. An isolation and communications element (ICE) has an instrument port and an electrically isolated loop port. The instrument port is in communications with the connector and the loop port is in communications with the breakable conductor. The ICE generates a control output responsive to the discontinuity state to render the sensor inoperable.

    摘要: A pulse oximetry sensor includes reusable and disposable elements. To assemble the sensor, the reusable element is snapped or slid within assembly mechanisms of the disposable element. In one embodiment, the reusable element includes protrusions while the disposable element includes tabs which receive the protrusions. In another embodiment, the reusable element includes neck portions and the disposable element includes straps which receive the neck portions. In any event, the assembly provides longitudinal movement between elements.
