Abstract
Methods and systems for determining a lifespan of an accessory device for a medical device such as a defibrillator are provided. An example method includes detecting an impedance of an electrode gel disposed on an electrode, determining environmental conditions to which the accessory device has been exposed, and using the impedance and environmental conditions to predict the expected lifespan of the accessory device.
Claims20
A system, comprising:
- an accessory device for a defibrillator, the accessory device comprising:
- an electrode;
- an electrode gel comprising a dielectric material disposed on a surface of the electrode;
- and
- a sensor configured to detect an environmental condition of the accessory device;
- a computing device comprising:
- a processor configured to:
- determine an impedance of the electrode gel;
- and
- predict a lifespan of the accessory device using the impedance of the electrode gel and the environmental condition of the accessory device;
- and
- an output device configured to output the lifespan of the accessory device.

A testing device, comprising:
- an accessory device comprising:
- an electrode;
- an electrode gel disposed on a surface of the electrode;
- and
- a sensor configured to detect an impedance of the electrode gel;
- an output device;
- and
- a processor configured to:
- identify a trend in the impedance of the electrode gel;
- predict, by analyzing the trend, an estimated life remaining of the accessory device;
- and
- cause the output device to output an indication of the estimated life remaining of the accessory device on the output device.
9 more elements
A method comprising:
- measuring, via an impedance sensor, an electrical impedance of an electrode gel of an accessory device;
- determining a trend of the electrical impedance of the electrode gel over time;
- determining a life expectancy of the accessory device by inputting the trend of the electrical impedance of the electrode gel over time into a trained predictive model, the predictive model being trained by training data comprising previous measurements of electrical impedances of other electrode gels;
- and
- outputting the life expectancy of the accessory device.
