Description

Technical Field

[0001] The utility model relates to the field of 13C breath analyzer accessories, in particular to an air chamber component applied to a 13C breath analyzer. Background Art

[0002] Helicobacter pylori is a spiral bacterium that exists in the patient's stomach and duodenal bulb. It was first isolated from the human stomach in 1983. It has been proven to cause chronic gastritis, peptic ulcers, and even malignant lesions such as gastric cancer and gastric lymphoma. It is contagious to a certain extent. At present, 13C breath analyzers are widely used to detect gastric Helicobacter pylori. 13C breath testing uses the characteristics of Helicobacter pylori being rich in urease. The subject is given a trace amount of 13C-urea orally. The urease produced by Hp in the stomach catalyzes the rapid hydrolysis of urea into ammonia and 13CO2. The latter enters the blood and is excreted from the body in the form of exhalation after gas exchange in the lungs. Collecting exhaled samples and measuring 13CO2 can analyze whether Hp infection exists. The basic principle of the 13C breath analyzer currently produced in China is that the infrared light emitted by the light source is irradiated onto the receiving sensor after passing through the air chamber filled with the gas to be tested, and the concentration of the gas to be tested is determined according to the value on the sensor, thereby determining whether Helicobacter pylori exists. The air chamber is an important component for detecting gas in the 13C breath analyzer. The existing air chamber is directly installed in the analyzer. When performing a breath test on the patient, it can only blow air into the air chamber, which causes the patient to need to ventilate. In the process of ventilation, it is inevitable that the patient will ventilate without completely leaving the air chamber, which can easily cause a certain impact on the detection accuracy.
