Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a Helicobacter pylori rapid detection test stick. Background Art

[0002] Helicobacter pylori (Hp) is one of the bacteria with the highest infection rate in the world. More than 70% of people infected with Hp have no obvious symptoms, while 80% of people with obvious gastric symptoms such as gastric ulcers and duodenal ulcers that are difficult to cure are HP carriers. The risk of gastric cancer in people infected with Hp can be increased by 4 to 6 times compared with the normal population. The International Agency for Research on Cancer under the World Health Organization has classified Hp as a Class I carcinogen for gastric cancer. In order to improve the treatment effect during medical testing and treatment due to the infectiousness of Helicobacter pylori, it is recommended that infected people and their family and friends undergo simultaneous testing and treatment.

[0003] With the widespread popularization of Helicobacter pylori, people have a certain understanding of the harm and infectiousness of Helicobacter pylori, and have gradually paid attention to gastric diseases caused by Helicobacter pylori, as well as the necessity of simultaneous testing and treatment of family members. In the testing link, with the development of various testing methods, more and more non-invasive testing reagents and test sticks are applied to the market, and people can buy the tests by themselves. In the existing tests, most testers collect samples by themselves, add reagents to the samples or smear the samples on test papers for testing. These testing products need to be operated strictly according to the steps in actual use, and have a certain degree of standardization. However, the differences in personnel and the non-standard operation make it easy for deviations to occur when diluting and smearing samples, affecting the test results, and inconvenient for test personnel to operate. At the same time, most of the existing testing products, testing reagents, test papers, and sampling swabs are packaged separately. When testing in units of family members, these accessories are relatively scattered, and it is more troublesome to use and store them. Summary of the invention

The test paper is moved by pulling the sliding rod and then folded, so that it moves to the bottom of the fourth cavity and is immersed in the reagent solution. In this process, the folded test paper wraps the rotating sampling swab, further increasing the area of ​​the sampling swab to apply the sample and improving the uniformity of application. At the same time, due to the infectious nature of Helicobacter pylori, family members usually need to be tested simultaneously during the examination. Multiple installation boxes are arranged in the above-mentioned base box, so that when purchasing test sticks according to the number of family members, multiple-person single-zone test sticks can be purchased, which reduces the problem of excessive packaging caused by the modularization of traditional test sticks or test paper products, and the accessories are scattered after purchasing multiple quantities, which is inconvenient to use and store.

By arranging multiple mounting boxes 6 through the No. 1 cavity 2, the detection helper can detect a single area by multiple people at a time, avoiding the problem of scattered accessories after purchasing multiple quantities, which is inconvenient to use and store.

[0021] Working principle: When using the Helicobacter pylori rapid test stick, the user first opens the slide cover 4 to the left to take out the sampling swab from the No. 2 chamber 3 for routine sampling. After the sampling is completed, the sampling swab is placed on the test paper between the No. 1 chamber 2 and the left opening of the installation box 6, and the sampling swab is pressed into the gear ring 164. During the inspection, the user first presses the button 12 to push forward, driving the connecting rod 153 to move forward in the first groove 152 to disengage from the limit, and then presses downward to make the sealing plate 11 and the liquid box 10 move downward to the bottom in the No. 3 chamber 7. During this process, the top head 13 will pierce the liquid outlet 14, and the reagent liquid in the liquid box 10 will flow out of the liquid outlet 14 and reach the bottom of the No. 4 chamber 8; During this process, when the liquid box 10 drives the linkage rod 167 and the slider 162 to move downward at the same time, the second rack 166 causes the downwardly moving toothed ring 164 to rotate in the third slide groove 163. When the toothed ring 164 moves downward and disengages from the second rack 166, it stops rotating until it moves downward and engages with the first rack 165 and rotates in the opposite direction again until the liquid box 10 slides to the bottom of the No. 3 cavity 7. During this process, the sampling swab rotates and moves downward with the toothed ring 164. When the sampling swab rotates and moves downward, it will contact the test paper between the slide bar 173 to make it move downward synchronously. The slide bar 173 is pulled by the downwardly moving test paper to move relatively close to the fourth groove 171, so that the test paper is folded and follows the sampling swab to move downward into the No. 4 cavity 8 and immerse in the reagent liquid. When the liquid box 10 is pressed to the bottom of the No. 3 cavity 7, the button 12 is pushed backward to drive the connecting rod 153 to move to the limit position below the No. 1 hole groove 154, release your hand and wait for the test paper, reagent solution and sample to fully react, then press and push the button 12 to move forward, the first spring 9 resets and drives the liquid box 10 to move up and reset, the connecting rod 167 drives the gear ring 164 and the sampling sign to reset, and the third spring 172 resets synchronously after the sampling sign on the test paper moves up and no longer conflicts, so that the sliding rod 173 moves to the initial position and tightens the test paper, and then the sampling sign is pulled out to complete the test.
