Abstract
A physiological monitor has a sensor port configured to attach and communicate with a sensor. A processor board is in communications with the sensor port and has a board digital signal processor (DSP). Firmware residing on the processor board is executable by the board DSP so as to calculate physiological parameters in response to a sensor signal received from the sensor. Upgrade tools are individually attachable to the sensor port in lieu of the sensor so as to designate to the processor board which of the physiological parameters, if any, to calculate when the sensor is attached to the sensor port.
Claims20
A parameter upgrade system comprising:
- a physiological monitor having a sensor port configured to attach and communicate with a sensor;
- a processor board in communications with the sensor port having a board digital signal processor (DSP);
- a plurality of firmware instructions residing on the processor board and executable by the board DSP so as to calculate a plurality of physiological parameters in response to a sensor signal received from the sensor;
- and
- an plurality of upgrade tools individually attachable to the sensor port in lieu of the sensor so as to designate to the processor board which of the physiological parameters, if any, to calculate when the sensor is attached to the sensor port.
A parameter upgrade method comprising:
- providing a physiological monitor having a sensor port configured to communicate with a sensor so as to calculate a plurality of parameters associated with a physiological state of a living being;
- configuring the sensor port so as to communicate with any of a plurality of upgrade tools in lieu of the sensor;
- and
- attaching a first upgrade tool to the sensor port so as to communicate to the monitor which of the parameters should be made available for output by the monitor.
A parameter upgrade method comprising:
- providing a processor board having a sensor port that is adapted to communicate with a physiological sensor, the processor board capable of calculating a plurality of physiological parameters in response to a sensor signal received from the sensor;
- making a first set of the parameters available to the processor board via a first upgrading set of sensor port communications so that the processor board is configured to calculate the first set of parameters in response to the sensor signal;
- and
- enabling the available first set of parameters via an enable sensor port communications so that the processor board will calculate and output the available first set of parameters in response to the sensor signal.
