AI Technical Summary

Problems solved by technology

Because the stability of hypochlorite and phenate is not good, and the carrier is agar gel, urea will be decomposed in advance in this system, resulting in insufficient substrate urea during detection, resulting in inability to accurately detect
And it takes 1-3 hours for the test result
[0005] Helicobacter pylori produces urease, which takes a certain amount of time to decompose urea, so the previous rapid urease method takes a lot of time to detect each sample, which is not conducive to large-scale screening.

Abstract

The invention provides a kit capable of rapidly detecting helicobacter pylori. The kit adopts a rapid culture method to shorten the detection time, and the kit also uses an ammonia time collecting agent and a buffer pair to improve the detection accuracy and reduce the misjudgment rate of clinical medical personnel. The kit can be used for large-scale clinical screening to prevent helicobacter pylori infection and propagation.

Description

technical field [0001] The application relates to the field of medical equipment, is a kit for detecting Helicobacter pylori, and belongs to the field of medicine. Background technique [0002] Helicobacter pylori lives in the pyloric part of the human stomach and the oral cavity, and is one of the most common bacterial pathogens. Half of the world's population has been infected with Helicobacter pylori, and in some countries almost 90% of the population has been infected with this bacterium. People are usually infected at an early age, reaching 50% under the age of 5 years. This bacterial infection first causes chronic gastritis, leading to gastric ulcer and gastric atrophy, and in severe cases, it develops into gastric cancer. [0003] According to statistics, the incidence of atrophic gastritis and gastric cancer is higher in people who are first infected with Helicobacter pylori at an earlier age, and there is a parallel relationship between Helicobacter pylori infecti...
