Portable detection equipment and detection method for rapid screening of liver diseases

Abstract

The invention discloses portable detection equipment for rapid screening of liver diseases and a detection method of the portable detection equipment. The device comprises a sample gas sampling bag, an inert gas carrying bottle, a micro electromagnetic valve integrated module, an enrichment device, a chromatographic column, a sensing unit and a single-chip microcomputer unit, wherein a micro electromagnetic valve integrated module enables sample gas and inert gas flowing through a micro channel to flow through the enrichment device and the chromatographic column respectively, sample gas and the inert gas enter the enrichment device or the chromatographic column after channel switching, the sensing unit senses the entering sample gas and performs electric signal extraction, all the modulesare controlled by the single-chip microcomputer unit to transmit and interact signals, and rapid screening and diagnosis of liver diseases are conducted through a mode recognition algorithm in the single-chip microcomputer unit according to fingerprint features of liver disease characteristic gas of different degrees. The method has advantages of being intelligent, low in detection cost, simple, safe, short in detection time, easy to carry and the like, and can be used for preliminary disease screening in families, communities, clinics and other wider occasions.

Description

technical field [0001] The invention relates to the field of liver disease detection, in particular to a portable detection device for primary screening of liver disease and a detection method thereof. Background technique [0002] In recent years, liver diseases have developed rapidly around the world, affecting both developed and emerging countries. As of the end of December 2015, there were approximately 188 million, 431 million, and 101 million cases of major chronic liver disease in Europe, China, and the United States, respectively. Among the chronic liver disease patients in China, the number of patients with hepatitis B, hepatitis C, alcoholic fatty liver disease, and non-alcoholic fatty liver disease is about 93.14 million, 24.31 million, 246.35 million, and 68.27 million, respectively. According to a latest report by the International Center for Cancer Research in 2018, the incidence of liver cancer in China ranks ninth, and according to population size, the numbe...
