Diabetes diagnostic system for detecting respiratory gases based on electronic nose

Abstract

A diabetes diagnostic system for detecting respiratory gases based on an electronic nose.The diabetes diagnostic system comprises a respiratory gas collecting module, a gas information acquiring module, a feature extracting and screening module and a mode recognizing module, wherein the respiratory gas collecting module collects respiratory gases into a gas bag through a respiratory gas exchanging device; the gas information acquiring module is used for reacting sensitive gases in the respiratory gases sent by the gas bag through a micro-cantilever resonant type gas sensitive sensor, converting concentration information of the sensitive gases into corresponding resonant frequency signals and sampling the resonant frequency signals; the feature extracting and screening module conducts feature extracting and feature screening on the sampled signals, the signals subjected to feature extracting and screening are transmitted to the mode recognizing module; the mode recognizing model conducts training and recognizing on acquired data through a mode recognizing method.The system can achieve quick non-invasive diagnosis on diabetes, and has the advantages that the noninvasion is achieved, price is low, reliability is high, real-time online measuring and portable design can be achieved, the analysis time is short, and operation is easy.

Description

technical field [0001] The invention relates to a diabetes diagnosis system for detecting breathing gas based on an electronic nose. Background technique [0002] For a long time, the diagnosis of diabetes has been mainly through biochemical blood glucose measurement and rapid blood glucose meter method. First of all, these two methods are an invasive detection method based on blood tests, which will cause different degrees of damage to the human body. At the same time, the biochemical instrument detection method is relatively expensive, and the result analysis period is long, making it difficult to achieve the purpose of real-time detection; and the rapid blood glucose meter will be affected by the depth of the needle, whether the blood is drawn naturally, and the amount of blood due to individual differences. How much, whether the alcohol is wiped clean and other objective factors, and the blood collection needle and test paper can only be used once. Contents of the inv...
