Abstract
This patent is a combined non-invasive method of monitoring glucose level. Monitoring the concentration of glucose level in human blood and tissue was developed by a combined non-invasive technique. This combined method includes skin temperature and pulse wave measurement. All these measurements are used to calculate the blood glucose level. This method also can be used to measure the diabetes related damage of micro arterial.
Claims2
A non-invasive method of determining blood glucose level in a patient comprising:
- calculating dissipated heat by measuring room temperature and body temperature of the patient;
- calculating blood oxygen saturation;
- determining a first glucose value using the calculated dissipated heat and the blood oxygen saturation;
- calculating a glucose coefficient using pulse wave analysis;
- and
- determining blood glucose level using the first glucose value and the glucose coefficient.
3 more elements
A method of determining blood glucose level of an individual comprising:
- determining body temperature of the individual;
- determining blood oxygen saturation;
- calculating blood flow for the individual using a pulse waveform from the individual;
- calculating a body heat coefficient and a blood flow coefficient by comparing the waveform from the individual to at least one waveform from a library of waveforms;
