Description

Helicobacter pylori detector

Technical Field

The invention relates to the technical field of medical detection instruments, in particular to a helicobacter pylori detector.

Background

Helicobacter pylori was first isolated from a biopsy specimen of the gastric mucosa of a patient with chronic active gastritis by australian scholaren, robin Warren (j.robin Warren) and Barry marshall (Barry j.marshall) in 1983. Helicobacter pylori is a gram-negative and microaerophilic bacterium, and lives in various areas of the stomach and the duodenum, and can cause slight chronic inflammation of the gastric mucosa, or even gastric and duodenal ulcer and gastric cancer, people are the only natural hosts of the helicobacter pylori, the infection rate of people is high, and the infection rate of people all over the world is as high as 30-50%. Helicobacter pylori can cause many diseases, and thus is very important for its clinical diagnosis and treatment.

There are currently several commonly used modes of helicobacter pylori detection: 1. blood drawing test: the blood drawing method is used for detecting the helicobacter pylori antibody level in serum. The test results are positive because corresponding antibodies are produced in humans after infection with H.pylori, but it usually takes several months and a half. Therefore, when the detection is carried out at the initial stage of helicobacter pylori infection, false negative results often appear in the detection result, and the patient loses the optimal treatment opportunity.

2. Gastroscope sampling detection: when the patient needs gastroscopy, the 'lift' sampling can be carried out, and the biopsy sampling is carried out at the same time, so as to detect whether the helicobacter pylori exists. If positive, H.pylori infection can be diagnosed as positive. Culture and drug susceptibility testing may also be added from time to time in order to develop an appropriate treatment for the patient. After the gastroscope downsampling, polymerase chain reaction can be adopted, the sensitivity is high, and the result is reliable; the method can also be used for quickly detecting the urease, is simple and quick, and has unreliable results due to short observation time or certain factors.

3. Breath sampling test: the test has high sensitivity, high detection rate, high coincidence rate and no pain to patients. It is the most popular method for detecting helicobacter pylori in recent years.

Urea [14C ] breath test is a helicobacter pylori diagnostic method which is currently widely used internationally and domestically. Based on the respiratory detection principle of radioactive isotope C14, the characteristic that helicobacter pylori is rich in urease is utilized, and the micro-dose C-urea is orally taken by a detected person, so that the urease of the helicobacter pylori in the stomach catalyzes C-urea, and finally the C-urea is exhaled in a CO2 mode through the lung.

The helicobacter pylori detector is a nuclear radiation detector and is specially used for a 14C-urea breath test, and a collected breath sample is measured, so that whether helicobacter pylori is infected is diagnosed, but the breath card of the conventional helicobacter pylori detector cannot prevent air leakage, and a detection gas collected after the expiration is finished flows out through an exhalation port to cause certain detection deviation, and the conventional device cannot perform large-batch centralized sampling detection, so that cross infection and effective disinfection operation cannot be well treated in the detection process.
