Abstract
Disclosed herein are systems and methods for non-invasively monitoring blood glucose levels with a level of accuracy that is high enough to replace invasive methods such as finger prick devices and others. In some examples, glucose values are determined using a patient's electrocardiogram (ECG) signals. Additionally, glucose values may additionally be determined using an impedance spectroscopy based method and then combined with glucose values determined using an ECG waveform to output a blood glucose value.
Claims20
A system for monitoring glucose values of a patient, the system comprising:
- at least two electrodes configured to output electrical data;
- a display;
- a memory;
- a control system coupled to the memory comprising one or more processors, the control system configured to execute a machine executable code to cause the control system to:
- receive a set of electrical data output from the at least two electrodes;
- process the set of electrical data to output a set of electrocardiogram (ECG) features;
- process the set of ECG features to output an ECG-based blood glucose level;
- and
- store the ECG-based blood glucose level in the memory;
- wherein process the set of ECG features to output the ECG-based blood glucose level comprises determining the ECG-based blood glucose level based on amplitude difference ratios of the set of ECG features and time difference ratios of the set of ECG features.
A method for monitoring glucose values of a patient, the method comprising:
- acquiring, via at least two electrodes, a set of electrical data;
- receiving, via a control system, the set of electrical data from the at least two electrodes;
- processing, via the control system, the set of electrical data to output a set of ECG features;
- processing, via the control system, the set of ECG features to output an ECG-based blood glucose level;
- and
- displaying the ECG-based blood glucose level on a display;
- wherein processing the set of ECG features to output the ECG-based blood glucose level comprises determining the ECG-based blood glucose level according to amplitude difference ratios of the set of ECG features and time difference ratios of the set of ECG features.
