Helicobacter pylori detector and method based on mid-infrared light absorption

Abstract

The invention discloses a helicobacter pylori detector and method based on mid-infrared light absorption, the helicobacter pylori detector comprises a mounting bottom plate, a first circuit board, a second circuit board, a first mounting shell, a second mounting shell, a main box body, a damping assembly, a detection assembly, a shunt tube and a display panel, the top of the mounting bottom plate is provided with the first circuit board and the second circuit board, and the first mounting shell and the second mounting shell are respectively arranged on the first circuit board and the second circuit board. According to the invention, the shunt tube is used for being in butt joint with the first access tube and the second access tube at the same time, and during ventilation, the first detection tube and the second detection tube are used for detecting the concentration of C and 12C respectively, so that the detection cost is reduced, and the detection efficiency is improved; by arranging the detection assembly, the intensity of light irradiated on the first sample plate and the second sample plate is enhanced, then the detection accuracy is ensured, vibration is relieved by arranging the damping assembly, damage to the internal structure caused by vibration is avoided, and thus the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the field of detection equipment for Helicobacter pylori, in particular to a detection instrument and method for Helicobacter pylori based on mid-infrared light absorption. Background technique [0002] Helicobacter pylori is a highly parasitic bacterium with strong acid resistance and viability. The human stomach is a particularly acidic place. Many stomach diseases are caused by the infection of Helicobacter pylori in the stomach. Therefore, the detection of Helicobacter pylori infection is particularly important. At present, the detection methods for Helicobacter pylori are divided into invasive detection and non-invasive detection. The detection methods mainly include microbiological detection, morphological detection, Serum immunological detection method and urea breath test. Although the invasive detection method has high specificity, it will cause certain damage to the human body. The urea breath test in the non-invasive...

[0002] Helicobacter pylori is a highly parasitic bacterium with strong acid resistance and viability. The human stomach is a particularly acidic place. Many stomach diseases are caused by the infection of Helicobacter pylori in the stomach. Therefore, the detection of Helicobacter pylori infection is particularly important. At present, the detection methods for Helicobacter pylori are divided into invasive detection and non-invasive detection. The detection methods mainly include microbiological detection, morphological detection, Serum immunological detection method and urea breath test. Although the invasive detection method has high specificity, it will cause certain damage to the human body. The urea breath test in the non-invasive detection method, by giving the tester an isotope-labeled urea reagent, Then collect and detect the isotope concentration in the exhaled gas after taking the medicine, and then compare the discrimination standard of Helicobacter pylori infection, and then complete the judgment of Helicobacter pylori infection. Generally, an isotope ratio mass spectrometer is needed to detect the gas, but the use of mass spectrometer It requires high professional knowledge, it is difficult for ordinary personnel to operate, and the detection efficiency is low, and the detection cost is high. Although the use of infrared light gas detection equipment reduces the detection cost, it can only detect one gas component at a time, and cannot simultaneously detect C and 12 The concentration of C affects the efficiency of detection; and most of the existing infrared light gas detection equipment has simple structure, no focusing structure, and the light is emitted radially. After passing through the gas chamber, only a small part can pass through the window lens to irradiate The photosensitive surface of the sensor affects the accuracy of detection; the existing detection equipment does not have a good shock absorption mechanism, and the vibration will cause damage to the parts of the equipment, thereby shortening the service life of the equipment; therefore, the design of the pyloric screw based on mid-infrared light absorption Bacteria detector is very necessary
