Abstract

The invention discloses a breath analyzer which can measure ketone body level through a noninvasive measurement method (breath analytic method) on the basis of the limitation of a ketone body level measurement method in the prior art. The breath analyzer can achieve real-time and accurate measurement on acetone concentration of human breath and directly display the blood ketone body level and reference blood glucose level. The breath analyzer also can synchronously upload data to network and displays the data on various electronic terminal devices. The breath analyzer allows diabetic patients, epileptic patients and other patients who need to measure the ketone body level and know the blood glucose level to know metabolism status themselves in real time, thereby promoting management and treatment of diseases and further significantly improving health condition and living quality.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to an acetone breath analyzer for non-invasively measuring ketone body levels. Background technique [0002] The present invention relates to an acetone breath analyzer for non-invasive measurement of ketone body levels. The analyzer is based on ultra-sensitive, highly selective cavity ring-down spectroscopy (CRDS). It is mainly aimed at monitoring the concentration of ketone bodies during the supervision and treatment of diabetic patients and epileptic patients (human and animal). However, in the current monitoring methods, blood samples need to be taken for blood measurement, which is painful and susceptible to infection, which seriously affects the quality of life. Urine testing can only Showing semi-quantitative measurement, unable to provide an accurate reference for disease regulation and treatment, thus inventing an acetone based on CRDS technology for non-invasive measu...
