Background Helicobacter pylori is a gram-negative bacterium, mainly distributed in gastric mucosal tissue, and is strongly associated with the occurrence of gastric ulcers and duodenal ulcers, belonging to a class of carcinogen lists. The metabolic activity of helicobacter pylori (Hp) can produce highly active urease, which is not present in mammalian cells, and thus, the presence of urease in the human stomach can be used as evidence of helicobacter pylori (Hp) infection in humans. 14 The C-urea expiration detection method is a common method for clinically detecting helicobacter pylori, and after a patient orally takes 14 C-urea, if helicobacter pylori exists in the stomach, the produced urease can quickly decompose urea into carbon dioxide and ammonia, the carbon dioxide enters the lung through blood to be discharged from the body, 14 CO2 exhaled by the patient is collected and then is measured on a helicobacter pylori detector, so that whether helicobacter pylori infection exists in the stomach can be diagnosed, and the method is a safe and high-cost-performance noninvasive detection means. A helicobacter pylori detector based on 14 C-urea expiration detection method is a device which detects a gas collecting card with a marked sample to be detected and provides basis for medical staff to diagnose stomach diseases. When the gas collecting card is tested, high-speed particles are injected into the Geiger-Muller pipe, the energy of the particles ionizes and conducts the gas in the pipe, and a rapid gas discharge phenomenon is generated between the filament and the pipe wall, so that a pulse current signal is output, at the moment, the software can perform counting processing, and the negative and positive of the gas collecting card are judged according to the counting result. When the gas collecting card is pulled out, certain high-speed particles still remain in the measuring chamber, radiation residues exist, a pulse current signal is output to form detection artifacts, the detection result of a negative sample is false positive, misjudgment is caused on the yin and yang of the sample, and the accuracy of detection is affected.
