WEARABLE DEVICE FOR NONINVASIVE MEASURING THE PARTIAL PRESSURE OF TRANSCUTANEOUS CO2 OF A PERSON AND RELATED METHOD OF MEASUREMENT

Deep studies carried out by the inventors about why the first prototype gave so largely inaccurate measurements, lead the inventors to investigate about what takes place into the chamber. Without being bound to a theory, it has was made the hypothesis that carbon dioxide saturated the chamber after a few minutes of testing and this could have been a main cause for inaccuracy of the first prototype. To solve this problem, it has been designed a wearable device for non-invasive measurement of the partial pressure of transcutaneous CO2 of a person as defined in the enclosed claim 1. A method of measuring in a non-invasive manner a partial pressure of transcutaneous CO2 of a person is also disclosed. This method may be implemented by 30 running a software in a microcontroller of the wearable device of this invention. Preferred embodiments are defined in the dependent claims.
