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.
