Abstract

The invention discloses a CO2 expiration isotope detector and an analysis method. The CO2 expiration isotope detector comprises: an infrared laser, an optical cavity and an infrared detector which are sequentially arranged, wherein the optical cavity is provided with an air inlet and an air outlet; at least one expiration channel which is communicated with the air inlet, wherein the expiration channel is used for introducing CO2 into the optical cavity for expiration; and an air outlet channel which is communicated with the air outlet. Laser emitted by the infrared laser is transmitted to the infrared detector through the optical cavity. The infrared laser is adopted as a light source, and because the difference between absorption wavelengths of CO2 of different isotopes is small, when the infrared laser is adopted, the wavelength of laser emitted by the infrared laser can be accurately controlled, so that the CO2 of different isotopes can be accurately distinguished, and the analysis accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of breath isotope detection, in particular to a CO 2 Breath isotope detector and analysis method. Background technique [0002] Helicobacter pylori is one of the most common gastric pathogens in the human stomach and is closely related to chronic bronchitis and peptic ulcer disease. This microorganism has high urease activity, which enables it to hydrolyze urea in gastric juice to produce carbon dioxide and ammonia. [0003] Based on body urease activity 13 C urea breath test ( 13 C-UBT) is widely used as a non-invasive diagnostic method to specifically detect whether there is Helicobacter pylori infection in the stomach. In the prior art, 13 The accuracy of C urea breath test is low. [0004] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a CO 2 The breath isotope detecto...
