Abstract
A sensor interface is configured to receive a sensor signal. A transmitter generates a transmit signal. A receiver receives the signal corresponding to the transmit signal. Further, a monitor interface is configured to communicate a waveform to the monitor so that measurements derived by the monitor from the waveform are generally equivalent to measurements derivable from the sensor signal.
Claims6
A pulse oximetry system comprising:
- a receiver configured to communicate with a monitor device;
- and
- a wrist-mountable pulse oximetry device including:
- a wrist mount usable to mount the wrist-mountable pulse oximetry device on a wrist of a user;
- a housing coupled to the wrist mount;
- a sensor interface housed by the housing and configured to receive a sensor signal from a pulse oximetry sensor, the sensor signal indicative of oxygen saturation and pulse rate of the user;
- and
- a transmitter housed by the housing and configured to:
- modulate a first baseband signal responsive to said sensor signal so as to generate the transmit signal;
- and
- wirelessly transmit the transmit signal to the receiver,
- wherein the receiver is further configured to:
- receive the wirelessly transmitted signal from the wrist-mountable pulse oximetry device;
- and
- adapt the received wirelessly transmitted signal to a monitor-compatible signal utilizing characterization information specific to the monitor device, the monitor-compatible signal adapted for compatibility with the monitor device, the monitor-compatible signal usable by the monitor device to provide physiological parameter measurements consistent with the sensor signal received from the pulse oximetry sensor.
