Wrist-mounted physiological measurement device
View Patent ↗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.
1. 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.
2. The pulse oximetry system of claim 1 , wherein the wrist mount comprises a wrist strap.
3. The pulse oximetry system of claim 1 , wherein the wrist-mountable pulse oximetry device further includes:
one or more input mechanisms useable by the user to affect at least one of the operational mode or characteristics of the wrist-mountable pulse oximetry device.
4. The pulse oximetry system of claim 3 , wherein the one or more input mechanisms comprise keys.
5. The pulse oximetry system of claim 1 , wherein adapting the received wirelessly transmitted signal further includes adapting the received wirelessly transmitted signal to the monitor-compatible signal such that the monitor-compatible signal is further usable by the monitor device to provide measurements of perfusion index and signal quality.
6. The pulse oximetry system of claim 1 , wherein the physiological parameter measurements include at least oxygen saturation and pulse rate of the user.
