Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kits, in particular to a Helicobacter pylori antigen detection kit. BACKGROUND

[0002] The Helicobacter pylori antigen detection kit is an in vitro diagnostic reagent for detecting whether Helicobacter pylori antigen exists in human samples (such as feces or blood), which mainly comprises a kit and a test paper arranged in the kit. Two detection openings are formed on the upper surface of the kit and extend to the inside of the kit to expose the test paper. The use method is as follows: the user uses a collection rod to collect a fecal sample, adds a solution into a test tube, and then puts the collection rod with the fecal sample into the test tube and stirs. Then, the user pours the stirred solution into a dropper, and then drips the stirred solution onto the test paper in the kit through the dropper. After 15 minutes, if a red reaction line appears on the test paper, it indicates negative, if two red reaction lines appear, it indicates positive, and if no red reaction line appears, it indicates invalid detection and needs to be re-detected.

[0003] However, the detection steps in the prior art are too troublesome, and when the user pours the stirred solution into the dropper, it is difficult to control and may cause the solution to be poured on the user's hand, resulting in a poor user experience. Therefore, the present application provides a Helicobacter pylori antigen detection kit to prevent the solution from being poured on the user's hand and improve the user experience. SUMMARY

[0004] In view of the deficiencies in the prior art, the purpose of the present application is to provide a Helicobacter pylori antigen detection kit to prevent the solution from being poured on the user's hand and improve the user experience.

[0005] The above-mentioned purpose of the present application is achieved by the following technical solution: a Helicobacter pylori antigen detection kit, comprising a reagent tube, a cover cap covering the tube opening of the reagent tube, a through hole formed in the middle of the cover cap, and a suction device inserted into the inside of the reagent tube through the through hole, the suction device comprising a suction cylinder, a suction pipe arranged at the end of the suction cylinder and communicating with the inside of the suction cylinder, and a pull rod inserted into the other end of the suction cylinder, the end of the pull rod inserted into the inside of the suction cylinder being provided with a friction block abutting the inner wall of the suction cylinder, and the bottom end of the reagent tube being placed with a test box with a test paper.

[0006] By adopting the above technical solution, the user first pulls out the cover and the suction device plugged into the cover from the reagent tube, then uses the suction tube to take the stool sample, then adds the solution into the reagent tube, and then covers the tube mouth of the reagent tube with the cover so that the suction device is located in the reagent tube, and then pushes the pull rod to make the friction block of the pull rod descend along the suction tube and press out the air inside the suction tube, so that the pressed air pushes the stool sample in the suction tube to fall into the solution in the reagent tube, and then shakes the reagent tube to accelerate the dissolution of the stool sample into the solution, and then pulls the pull rod to make the friction block rise along the suction tube and pass The external air is sucked into the suction tube through the suction tube, and the solution is driven into the suction tube at the same time. Then the suction tube is pulled out of the reagent tube, and the suction tube is aligned with the test paper of the test box. Then the pull rod is pushed to make the friction block descend along the suction tube and press out the air inside the suction tube, so that the pressed air pushes the solution in the suction tube to fall on the test paper of the test box. Wait for 15 minutes. The whole process is very simple and easy, and there is no need to pour the stirred solution into other objects again. This prevents the solution from pouring on the user's hands and improves the user experience.

[0007] Furthermore, a placement structure for placing a test box is provided at the bottom end of the reagent tube.

[0008] Furthermore, the placement structure includes a placement opening opened at the bottom end of the reagent tube and passing through the side wall of the reagent tube, and a partition plate arranged inside the reagent tube and located above the placement opening.

[0009] By adopting the above technical solution, although the setting of the suction device prevents the solution from pouring onto the user's hands, thereby improving the user's usage experience, when the user uses the suction device to drop the solution onto the test paper of the test box, the user needs to push the pull rod, and the suction cup needs to be fixed by the user's other hand when pushing the pull rod, which makes it impossible for the user to hold the test box, and the user needs to align with the test paper on the test box. If the user is far away from the test box, the user cannot align. If the user is close to the test box, the user may collide with the test box when pushing the pull rod, causing the test box to slide, and the solution cannot be accurately dropped on the test paper. The setting of the placement structure solves this technical problem. The bottom end of the reagent tube is divided into two layers by a partition plate. The upper part of the partition plate is used to hold the solution, and the user can insert one end of the test box into the reagent tube through the placement port under the partition plate to fix the test box. In this way, it is more convenient for the user to use the suction device to drop the solution onto the test paper of the test box.

[0010] Furthermore, a relative through hole is provided in the middle of the partition plate to form a connecting structure for the suction pipe to pass through the partition plate.

[0011] Furthermore, the connecting structure includes a connecting hole opened in the middle of the partition plate relative to the through hole and two receiving grooves opened on both sides of the connecting hole and opposite to each other. The connecting hole passes through the partition plate, and a filling structure for filling the connecting hole is provided in the receiving groove.

[0012] Furthermore, the filling structure includes a filling block inserted in the receiving slot and a spring arranged in the receiving slot for pushing the filling block to extend outside the receiving slot. One end of the spring is fixedly connected in the receiving slot, and the other end is fixedly connected to the filling block.

[0013] By adopting the above technical solution, although the placement structure makes it more convenient for the user to use the suction device to drop the solution onto the test paper of the test box, when the user pulls out the suction device that has absorbed the solution from the reagent tube, the part of the suction device that contacts the solution may be stained with the solution. This causes the solution stuck on the suction device to drip onto the table when the suction device is pulled out from the reagent tube, causing the user to need to clean it up later, which is very troublesome. The setting of the connecting structure solves this technical problem. Through the setting of the connecting structure, after the suction device absorbs the solution, it can pass through the partition plate through the connecting hole and directly spray the solution on the test box below the partition plate. The user only needs to remove the end of the test box that is exposed to the test paper. The user only needs to push the suction device so that the suction tube presses the filling plate into the storage groove to make the suction tube output the solution to the test paper on the test box.

[0014] Furthermore, a protective device is installed on the suction tube to prevent the stool sample from adhering to the suction tube.

[0015] Furthermore, the protective device includes a connecting sleeve sleeved on the suction pipe and a collecting portion fixedly arranged on an end of the connecting sleeve away from the suction pipe for collecting fecal samples.

[0016] By adopting the above technical solution, although the setting of the suction device prevents the solution from pouring onto the user's hands, thereby improving the user's experience, when the user pushes the pull rod to allow the squeezed air to push the stool sample in the suction tube into the solution in the reagent tube, the stool sample in the suction tube may not all fall into the reagent tube. This causes the user to absorb the solution through the suction device. If the user does not pay attention to the situation inside the suction device, the solution may drip onto the test paper of the test box with the stool sample that is not dissolved in the solution, which may cause errors in the test results. The setting of the protective device solves this technical problem. Through the setting of the protective device, the user first pulls the pull rod before collecting the stool sample. Move the pull rod to leave air in the suction cylinder, then put the connecting sleeve on the suction tube, use the collection part to collect the stool sample, then add the solution to the reagent tube, cover the tube mouth of the reagent tube with the sealing cap so that the suction device is located in the reagent tube, and then shake the reagent tube to mix the solution with the stool sample. When the solution needs to be extracted, push the pull rod to make the air in the suction cylinder flow out through the suction tube. At the same time, the outflowing air will push the connecting sleeve out of the suction tube, so that the suction tube can absorb the solution. This can prevent the stool sample from sticking to the inside of the suction tube. When the user needs to test again later, he only needs to clean the suction device and the reagent tube, then take a new test box and protective device to replace them and they can be reused.

[0017] Furthermore, the protective device is mainly made of plastic.

[0018] By adopting the above technical solution, the protective device made of plastic can collect samples more accurately without destroying the integrity of the samples or absorbing the visible components therein, thereby ensuring the accuracy of the test results.

[0019] Furthermore, a plug-in groove is provided on the edge of the tube mouth of the reagent tube, and a plug-in piece is fixedly provided on the edge of the bottom surface of the cover.

[0020] By adopting the above technical solution, the plug-in piece is inserted into the plug-in groove and the stability of the cover installed on the reagent tube is improved.

[0021] In summary, this application includes at least one of the following beneficial technical effects: By setting the suction device, the user pulls out the cover and the suction device inserted on the cover from the reagent tube, then takes the fecal sample with the suction tube, then adds the solution into the reagent tube, covers the pipe opening of the reagent tube with the cover so that the suction device is located in the reagent tube, then pushes the pull rod, so that the friction block of the pull rod descends along the suction cylinder, and the air in the suction cylinder is pressed out, so that the pressed air pushes the fecal sample in the suction tube into the solution in the reagent tube, then shakes the reagent tube to accelerate the dissolution of the fecal sample into the solution, then pulls the pull rod, so that the friction block ascends along the suction cylinder, and the external air is sucked into the suction cylinder through the suction tube, at the same time, the solution is brought into the suction tube, then pulls out the suction cylinder from the reagent tube, then aligns the suction tube with the test paper of the test box, then pushes the pull rod, so that the friction block descends along the suction cylinder, and the air in the suction cylinder is pressed out, so that the pressed air pushes the solution in the suction tube to fall on the test paper of the test box, after waiting for 15 minutes, the whole process is very simple and easy, and the stirred solution does not need to be poured into other objects again, so that the situation that the solution is poured on the user's hand is prevented, and the user's use experience is improved.

DETAILED DESCRIPTION

[0024] The application will be further described in detail below with reference to the drawings.

[0025] The embodiment, with reference to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ​​​​A Helicobacter pylori antigen detection kit includes a reagent tube 1, a cover 10 that tightly covers the tube mouth of the reagent tube 1, a through hole 11 opened in the center of the cover 10, and a suction device 2 that passes through the through hole 11 and penetrates into the interior of the reagent tube 1. This suction device 2 is composed of several key parts: one is a suction cylinder 20 as the main body, one end of which is connected to a suction tube 21, and the suction tube 21 is directly connected to the interior of the suction cylinder 20 for collecting samples; the other end is connected to a pull rod 22. A friction block 23 is provided at one end of the pull rod 22 that penetrates into the interior of the suction cylinder 20, and the circumference of the friction block 23 can fit tightly with the inner wall of the suction cylinder 20.

[0026] At the bottom of the test tube 1 lies a test cartridge 3 containing a test strip. The user first gently removes the cover 10 and its attached suction device 2 from the test tube 1, then accurately collects the stool sample using the suction tube 21. Next, add an appropriate amount of solution to the test tube 1 and replace the cover 10 on the tube opening, ensuring that the suction device 2 remains inside the test tube 1.

[0027] At this point, the user simply pushes the pull rod 22, and the friction block 23 slowly descends along the inner wall of the suction tube 20, simultaneously squeezing out the air inside the suction tube 20. This expelled air generates sufficient pressure to push the stool sample in the suction tube 21 into the solution in the reagent tube 1. To help the stool sample dissolve more fully in the solution, the user can gently shake the reagent tube 1.

[0028] After dissolution is complete, the user again operates the pull rod 22, this time pulling it upward, causing the friction block 23 to rise along the inner wall of the suction tube 20. During this process, the suction tube 21 uses the principle of negative pressure to draw external air into the suction tube 20. Simultaneously, due to the pressure difference, the solution is also drawn into the suction tube 21. The user can then remove the entire suction device 2 from the reagent tube 1 and align the suction tube 21 with the test paper in the test cartridge 3.

[0029] Finally, push the lever 22 again, causing the friction block 23 to descend and squeeze out the air in the suction tube 20. This air also pushes the solution in the suction tube 21 to drip onto the test paper. The user only needs to wait patiently for 15 minutes, and then observe the reaction on the test paper to obtain the test result.

[0030] The entire operation process is simple and easy, without the user having to transfer the stirred solution to another container, effectively avoiding the risk of the solution splashing on the user's hands and greatly improving the user experience. In addition, the edge of the tube mouth of the reagent tube 1 is also provided with a plug-in groove 12, and the bottom edge of the cover 10 is fixed with a matching plug-in piece 13. This design not only enhances the connection stability between the cover 10 and the reagent tube 1, but also makes the entire test kit safer and more reliable during carrying and use.

[0031] Although the design of the suction device 2 effectively prevents the solution from accidentally splashing onto the user's hands, significantly improving the user's convenience and satisfaction, there are still some problems during actual operation when the user tries to use the suction device 2 to accurately drip the solution onto the test paper in the test box 3. Specifically, the user needs to use one hand to push the pull rod 22 to operate the suction cup 20, and the other hand is needed to stabilize the suction cup 20. This operation method makes it impossible for the user to support the test box 3 at the same time. Due to the need to align with the test paper, if the user maintains a certain distance from the test box 3, it is difficult to ensure the accurate dripping of the solution; if the user is too close, it is easy to accidentally touch the test box 3 when pushing the pull rod 22, causing it to slide and shift, and then the solution cannot fall accurately on the test paper.

[0032] In order to solve this technical problem, the present embodiment provides a placement structure 4 at the bottom of the reagent tube 1. The placement structure 4 consists of two parts: one is a placement port 40 opened at the bottom of the reagent tube 1 and extending through the side wall, and the other is a partition plate 41 provided inside the reagent tube 1 and located above the placement port 40. By providing the partition plate 41, the bottom of the reagent tube 1 is divided into two layers of space, the upper layer being used to safely carry the solution, while the lower layer provides a convenient location for the user, allowing the user to easily insert one end of the test box 3 into the reagent tube 1 through the placement port 40, thereby achieving stable fixation of the test box 3. Such a design greatly simplifies the user's operating process, making it more convenient for the user to drip the solution onto the test paper using the suction device 2, without having to worry about the test box 3 sliding or the solution dripping deviation due to improper operation.

[0033] While the placement of the placement structure 4 facilitates the process of the user using the suction device 2 to drip the solution onto the test paper in the test box 3, this process still presents a technical problem: when the user needs to pull the suction device 2, which has already absorbed the solution, out of the reagent tube 1, some of the solution may be carried along due to the contact of some components of the suction device 2 with the solution. This carried-over solution may drip onto the table during the process of pulling out the suction device 2, causing the user to have to clean it up later, which is obviously not conducive to improving the overall user experience.

[0034] To address this technical issue, this embodiment provides a connecting structure 5 in the middle of the partition plate 41. The core of this connecting structure 5 is a connecting hole 50 that penetrates the partition plate 41, allowing the suction tube 21 to pass through the partition plate 41 when needed. Furthermore, opposite receiving grooves 51 are provided on either side of the connecting hole 50. These grooves 51 are equipped with filling structures 6 to ensure that the connecting hole 50 is effectively sealed when the solution is not being discharged.

[0035] The filling structure 6 consists of two parts: one part is the filling block 60 inserted into the receiving groove 51, which can fit tightly around the connecting hole 50; the other part is the spring 61 arranged in the receiving groove 51, one end of these springs 61 is fixed inside the receiving groove 51, and the other end is connected to the filling block 60. Through the elastic force of the spring 61, the filling block 60 can be continuously pushed to the outside of the receiving groove 51, thereby ensuring that the connecting hole 50 is tightly sealed by the filling block 60 under normal circumstances.

[0036] With this arrangement, after the suction device 2 has finished absorbing the solution, the user no longer needs to pull the suction device 2 out of the reagent tube 1. Instead, the user can directly pass the suction tube 21 of the suction device 2 through the partition plate 41 through the connecting hole 11 to spray the solution on the test box 3 located below the partition plate 41. The user only needs to simply place the end of the test box 3 that is exposed from the test paper into the reagent tube 1 to achieve accurate output of the solution. In this way, the problem of the suction device 2 dripping solution during the extraction process is completely avoided, which not only improves the user experience, but also makes the entire test kit usage process more convenient.

[0037] At the same time, the provision of the filling structure 6 also ensures that the solution will not be prematurely discharged to the test paper when it is not needed. During the process of mixing the stool sample and the solution, the spring 61 pushes the filling blocks 60 in the two receiving slots 51 to abut against each other, thereby effectively blocking the connecting hole 50. Only when the user needs to discharge the solution, by pushing the suction device 2 so that the suction tube 21 compresses the filling block 60 into the receiving slot 51, can the solution be discharged to the test paper. This arrangement not only ensures the accuracy of the test, but also avoids unnecessary waste and pollution.

[0038] Although the design of the suction device 2 has effectively avoided the risk of the solution pouring directly onto the user's hands, thereby significantly improving the user experience, in actual operation, when the user pushes the pull rod 22 to use the expelled air to push the stool sample in the suction tube 21 into the solution in the reagent tube 1, a technical problem may still be encountered: the stool sample in the suction tube 21 cannot always fall completely into the reagent tube 1. If this situation is not noticed by the user, when the solution is subsequently sucked through the suction device 2, the stool sample that is not dissolved in the solution may be carried by the solution and eventually drip onto the test paper of the test box 3. This residue of stool sample may not only interfere with the accuracy of the test results, but may also mislead the user's judgment.

[0039] To address this technical issue, this embodiment provides a protective device 7 on the suction tube 21. This protective device 7 consists of two parts: a connecting sleeve 70 that fits over the suction tube 21; and a collection portion 71 fixed to the end of the connecting sleeve 70 away from the suction tube 21. The collection portion 71 is specifically used to collect stool samples, ensuring the accuracy and integrity of the samples.

[0040] In practice, the user first pulls the pull rod 22 to create a certain amount of air space within the suction tube 20. Then, the connecting sleeve 70 is placed over the suction tube 21, and the desired stool sample is collected using the collection unit 71. Next, an appropriate amount of solution is added to the reagent tube 1, and the opening of the tube 1 is tightly covered with the cap 10, ensuring that the suction device 2 is firmly placed within the tube 1. At this point, gently shaking the tube 1 promotes thorough mixing of the solution and stool sample, preparing for subsequent testing.

[0041] When the solution needs to be extracted, the user simply pushes the pull rod 22 again, and the air in the suction cylinder 20 will flow out smoothly through the suction tube 21. At the same time, this outflowing air also generates a thrust, causing the connecting sleeve 70 to separate from the suction tube 21. This allows the suction tube 21 to absorb the solution without hindrance. Due to the timely detachment of the connecting sleeve 70, the fecal sample is firmly retained in the reagent tube 1, avoiding further contact with the solution, thereby effectively preventing the fecal sample from sticking to the inside of the suction tube 21.

[0042] In addition, when the user needs to perform the test again, he only needs to clean the aspiration device 2 and the reagent tube 1, and then replace them with a new test cartridge 3 and protective device 7. This design not only saves the user's cost and time, but also makes the entire testing process more flexible and convenient.

[0043] Specific implementation process: first, pull out the cover 10 and the suction device 2 plugged into the cover 10 from the reagent tube 1, then pull the pull rod 22 to leave air in the suction tube 20, then put the connecting sleeve 70 on the suction tube 21, and then use the collecting part 71 to collect the feces sample, then add the solution into the reagent tube 1, and then cover the tube mouth of the reagent tube 1 with the cover 10 so that the suction device 2 is located in the reagent tube 1, and then shake the reagent tube 1 to mix the solution and the feces sample, and then push the pull rod 22 to make the air in the suction tube 20 flow out through the suction tube 21, and at the same time, the outflowing air will push the connecting sleeve 70 out of the suction tube 21, so that The suction tube 21 absorbs the solution, and then the pull rod 22 is pulled to make the friction block 23 rise along the suction tube 20 and suck the external air into the suction tube 20 through the suction tube 21, while driving the solution into the suction tube 21. Then, the suction tube 20 is pushed, so that the suction tube 21 is retracted into the storage groove 51 against the filling plate, so that the suction tube 21 is aligned with the test paper on the test box 3. Then, the pull rod 22 is pushed to make the friction block 23 descend along the suction tube 20 and press out the air inside the suction tube 20. The pressed air pushes the solution in the suction tube 21 to fall onto the test paper in the test box 3. After waiting for 15 minutes, the test result can be observed.

[0044] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
