Method for measuring acetone in respiratory gas and implementation device thereof

Abstract

The invention discloses a method for measuring acetone in respiratory gas and an implementation device thereof, wherein a collected respiratory gas sample is injected into the absorption pool of a respiratory gas acetone measuring device; the measuring light is guided into the absorption pool of the respiratory gas acetone measuring device; the measured light absorption spectrum which transmits out of the respiratory gas sample passing through the absorption pool is measured by a light measurer; and the measured absorption spectrum of the respiratory gas sample is compared with the absorptionspectrum containing an acetone gas mixture with the known concentration through a computer system, thereby obtaining the content of the acetone in the respiratory gas sample. In the invention, the content of the acetone in the respiratory gas can be accurately and rapidly measured; the finish and disclosure of the acetone content measurement are the significant progress of a respiratory gas acetone measuring technique; and the progress of the respiratory gas acetone measuring technique is greatly boosted. According to the relation between the content of the acetone in the respiratory gas of ahuman body and diabetes, the method and device provided by the invention can be used for diagnosing the diabetes and can be widely used for the daily health examination of the diabetes and the rapid clinic screening of the diabetes.

Description

field of invention

[0001] The invention relates to a measurement technology of human respiratory gas, in particular to a measurement technology for acetone in respiratory gas, in particular to a method for measuring acetone in respiratory gas and an implementation device thereof. Background technique

[0002] Diabetes is a growing problem worldwide. The World Health Organization reported that the number of people with diabetes worldwide was 171 million in 2000 and is expected to rise to 336 million by 2030. At present, the incidence of diabetes in China is as high as 9.7%. There are nearly 100 million people with diabetes in the country and the incidence of diabetes is younger. China has become the fastest growing country and region in the world for diabetes, and surpassed India to become the largest country in diabetes. According to the forecast data released by the World Health Organization in 2005, if effective measures are not taken, between 2005 and 2015, stroke, diabe...
