Abstract

The invention relates to a sugar tolerance quantitative evaluation device based on breath testing. The device comprises a sampling pump, a sampling tube, a gas sensing unit, a monitoring unit, a display unit and a power supply unit. According to the device, breath components and concentrations before and after glucose intake are monitored through a breath testing device, quantitative evaluation ofsugar tolerance is realized, and the method can replace an invasive method of blood glucose measurement through blood drawing. The technical method has the advantages of being noninvasive, high in acceptance, sanitary, convenient to use and the like.

Description

technical field [0001] The invention relates to the technical fields of sensor technology, biomedical engineering, medical and health care, etc., and in particular to a quantitative evaluation device for sugar tolerance based on breath detection. Background technique [0002] Glucose tolerance test is a commonly used method to judge the ability of glucose tolerance, and it is a standard method for the diagnosis of diabetes. In the glucose tolerance test, subjects take fasting venous blood in the morning to measure blood glucose concentration, then take 75 grams of glucose at a time, and measure blood glucose once at 0.5, 1, and 2 hours (3 hours if necessary) after taking the glucose to measure blood glucose The time is the abscissa (0 o'clock when fasting), and the blood sugar concentration is the ordinate. Draw the glucose tolerance curve. Normal people reach the peak 0.5-1 hour after taking the sugar, then gradually decrease, and generally return to the normal value in abo...
