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.
Claims16
A wireless communications adapter configured to convert a wired patient monitor into a wireless patient monitor without requiring alterations to signal processing algorithms of the wired patient monitor in order for the wireless patient monitor to electronically determine measurement values of one or more physiological parameters determinable by the wired patient monitor, the wireless communications adapter comprising:
- a plug configured to plug into a sensor port of a wired patient monitor and electrically and mechanically mimic a monitor end of a patient cable of a wired sensor arrangement compatible with the sensor port of the wired patient monitor;
- a receiver configured to receive a wirelessly transmitted signal from a physiological sensor communications adapter, the wirelessly transmitted signal including information from which measurement values of one or more physiological parameters may be derived;
- and
- a processor configured to:
- obtain characterization information specific to the wired patient monitor;
- adapt the received wirelessly transmitted signal to a monitor-compatible signal utilizing the characterization information specific to the wired patient monitor, the monitor-compatible signal adapted for compatibility with the wired patient monitor, the monitor-compatible signal usable by the wired patient monitor to determine measurement values of one or more physiological parameters consistent with physiological data collected by a physiological sensor;
- and
- cause the monitor-compatible signal to be provided to the wired patient monitor via the plug and the sensor port of the wired patient monitor,
- whereby the wired patient monitor is converted to a wireless patient monitor.
