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 stirred solution is poured into a dropper, and the stirred solution is dropped 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, one end of the pull rod inserted into the inside of the suction cylinder is provided with a friction block abutting the inner wall of the suction cylinder, and the bottom end of the reagent tube is placed with a test box with a test paper.

[0006] By adopting the technical scheme, first, the user pulls out the cover and the suction device plugged on the cover from the reagent tube, then takes the fecal sample by using the suction tube, then adds the solution into the reagent tube, covers the tube 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 to drop into the solution in the reagent tube, then shakes the reagent tube to accelerate the dissolution of the fecal sample in 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 drop on the test paper of the test box, and after 15 minutes, the whole process is very simple and easy, and the user's experience is improved, and the situation that the solution is poured on the user's hand is prevented.

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

[0008] Further, the placement structure comprises a placement opening formed in the bottom end of the reagent tube and penetrating 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 technical scheme, although the setting of the suction device prevents the situation that the solution is poured on the user's hand, improves the user's experience, but when the user uses the suction device to drop the solution on the test paper of the test box, the user needs to push the pull rod, and the suction cylinder needs to be fixed by the other hand of the user, which causes the user to be unable to hold the test box, and the user needs to align the test paper on the test box, if the distance from the test box is far, the user cannot align, if the distance from the test box is close, the user may collide with the test box when pushing the pull rod, causing the test box to slide, so that the solution cannot be accurately dropped on the test paper, and the setting of the placement structure solves this technical problem, the bottom end of the reagent tube is divided into two layers by the partition plate, the solution is carried above the partition plate, and the test box can be inserted into the reagent tube through the placement opening by one end of the test box below the partition plate, so that the test box is fixed, so that the user uses the suction device to drop the solution on the test paper of the test box is more convenient.

[0010] Further, the middle part of the partition plate is provided with a relative through hole for a communication structure for the suction tube to pass through the partition plate.

[0011] Further, the communication structure comprises a connecting hole and two receiving grooves, the connecting hole is arranged in the middle of the partition plate and opposite to the through hole, the receiving grooves are arranged on both sides of the connecting hole respectively, the connecting hole penetrates the partition plate, and the receiving grooves are provided with a filling structure for filling the connecting hole.

[0012] Further, the filling structure comprises a filling block inserted into the receiving groove and a spring arranged in the receiving groove and used for pushing the filling block to extend out of the receiving groove, one end of the spring is fixedly connected to the receiving groove, and the other end is fixedly connected to the filling block.

[0013] By adopting the above technical scheme, although the placement structure is arranged to make the user use the suction device to drop the solution on the test paper of the test box more conveniently, when the user pulls out the suction device with the solution from the reagent tube, the part of the suction device in contact with the solution may be stained with the solution, which may cause the solution adhered to the suction device to drop on the desktop when the suction device is pulled out of the reagent tube, and the user needs to clean up subsequently, which is very troublesome. The communication structure solves this technical problem. Through the arrangement of the communication structure, after the suction device sucks the solution, the suction device can pass through the communication hole and the partition plate to directly spray the solution on the test box below. The user only needs to place the end of the test box with the test paper exposed in the reagent tube, so that the user can output the solution on the test paper of the test box without pulling out the suction device from the reagent tube. This can prevent the solution adhered to the suction device from dropping on the desktop when the suction device is pulled out of the reagent tube, improve the user experience, and make the user use the reagent box more conveniently. Through the arrangement of the filling structure, when the user mixes the fecal sample and the solution, the spring pushes the filling blocks in the two receiving grooves to abut against each other to block the connecting hole, so as to prevent the solution from falling on the test paper of the test box in advance. The user only needs to push the suction device to make the suction tube compress the filling block to retract into the receiving groove, so as to output the solution on the test paper of the test box.

[0014] Further, the suction tube is provided with a protective device used for preventing the fecal sample from adhering to the suction tube.

[0015] Further, the protective device comprises a connecting sleeve arranged on the suction tube and a collecting part arranged on the end of the connecting sleeve away from the suction tube and used for collecting the fecal sample.

[0016] By adopting the above technical scheme, although the setting of the suction device prevents the solution from being poured on the user's hand, improving the user's use experience, when the user pushes the pull rod to make the squeezed air push the fecal sample in the suction pipe into the solution in the reagent pipe, the fecal sample in the suction pipe may not all fall into the reagent pipe, which causes the user to suck the solution through the suction device, if the user does not notice the internal condition of the suction device, then the solution may drop on the test paper of the test box with the fecal sample not dissolved in the solution, which may cause the test result to have errors, and the setting of the protection device solves this technical problem, through the setting of the protection device, before the user collects the fecal sample, the user first pulls the pull rod to leave air in the suction cylinder, then the connecting sleeve is sleeved on the suction pipe, then the collecting part is used to collect the fecal sample, then the solution is added into the reagent pipe, then the cover is used to cover the pipe opening of the reagent pipe to make the suction device located in the reagent pipe, then the reagent pipe is shaken to make the solution and the fecal sample mix, when the solution needs to be extracted, the pull rod is pushed to make the air in the suction cylinder flow out through the suction pipe, and the air flowing out will push the connecting sleeve to separate from the suction pipe, so that the suction pipe sucks the solution, which can prevent the fecal sample from sticking to the inside of the suction pipe, and when the user needs to detect again later, the user only needs to clean the suction device and the reagent pipe, then take a new test box and the protection device to replace and reuse.

[0017] Further, the protection device is mainly made of plastic.

[0018] By adopting the above technical scheme, the protection device made of plastic can more accurately collect the sample, and will not damage the integrity of the sample or absorb the formed components therein, thereby ensuring the accuracy of the detection result.

[0019] Further, the pipe opening edge of the reagent pipe is provided with a plug-in groove, and the edge of the bottom surface of the cover is fixedly provided with a plug-in piece.

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

[0021] In summary, the present application has at least one of the following beneficial technical effects:

[0022] 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 the suction cylinder is pulled out of the reagent tube, and then the suction tube is aligned with the test paper of the test box, then the pull rod is pushed, 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, and after 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 solution poured on the user's hand is prevented, and the user's use experience is improved.

DETAILED DESCRIPTION

[0029] The application will be further described in detail below with reference to the drawings.

[0030] The embodiment, with reference to Figure 1 , Figure 2 ,​​​​Figure 3 、 Figure 4 and Figure 5 A Helicobacter pylori antigen detection kit comprises a reagent tube 1, a cover 10 tightly covering the mouth of the reagent tube 1, a through hole 11 formed in the center of the cover 10, and a suction device 2 penetrating through the through hole 11 and extending into the interior of the reagent tube 1. The suction device 2 is composed of several key parts: a suction cylinder 20 as the main body, one end of which is connected with a suction tube 21 directly communicating with the interior of the suction cylinder 20 for collecting samples, and the other end of which is inserted with a pull rod 22. The end of the pull rod 22 extending into the interior of the suction cylinder 20 is provided with a friction block 23, the peripheral surface of which can tightly adhere to the inner wall of the suction cylinder 20.

[0031] At the bottom of the reagent tube 1, a test box 3 containing test paper is placed. The user first needs to gently pull out the cover 10 and the suction device 2 thereon from the reagent tube 1, and then accurately collect the fecal sample by using the suction tube 21. Next, an appropriate amount of solution is added into the reagent tube 1, and the cover 10 is re-covered on the mouth of the reagent tube 1, ensuring that the suction device 2 still remains in the interior of the reagent tube 1.

[0032] At this time, the user only needs to simply push the pull rod 22, and the friction block 23 will slowly descend along the inner wall of the suction cylinder 20, while extruding the air in the interior of the suction cylinder 20. The extruded air will generate sufficient pressure to push the fecal sample in the suction tube 21 into the solution in the reagent tube 1. In order to make the fecal sample more fully dissolved in the solution, the user can gently shake the reagent tube 1.

[0033] After the dissolution is completed, the user operates the pull rod 22 again, this time pulling it upward, so that the friction block 23 rises along the inner wall of the suction cylinder 20. In this process, the suction tube 21 will use the principle of negative pressure to suck the external air into the suction cylinder 20, and at the same time, due to the action of pressure difference, the solution will also be brought into the suction tube 21. Subsequently, the user can pull out the entire suction device 2 from the reagent tube 1, and align the suction tube 21 with the test paper in the test box 3.

[0034] Finally, the pull rod 22 is pushed again to make the friction block 23 descend and extrude the air in the suction cylinder 20, and this air will also push the solution in the suction tube 21 to drop on the test paper. The user only needs to wait for 15 minutes to obtain the detection result by observing the reaction on the test paper.

[0035] The whole operation process is simple and easy, and the user does not need to transfer the stirred solution to other containers, thereby effectively avoiding the risk of solution splashing on the user's hands, greatly improving the user's experience. In addition, the edge of the pipe opening of the reagent tube 1 is also provided with a plug-in slot 12, and the bottom edge of the cover 10 is fixedly provided with a plug-in piece 13 matched therewith. This design not only enhances the connection stability between the cover 10 and the reagent tube 1, but also makes the whole reagent box more safe and reliable during carrying and using.

[0036] Although the design of the suction device 2 effectively avoids the situation that the solution accidentally splashes on the user's hands, significantly improves the user's convenience and satisfaction, but in the actual operation process, when the user tries to use the suction device 2 to accurately drop the solution into the test paper in the test box 3, there are still some problems. Specifically, the user needs to push the pull rod 22 with one hand to operate the suction cylinder 20, and the other hand needs to be used to stabilize the suction cylinder 20, which makes the user unable to hold the test box 3 at the same time. Due to the need to align the test paper, if the user keeps a certain distance from the test box 3, it is difficult to ensure the accurate dropping of the solution; if 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 causing the solution to not accurately fall on the test paper.

[0037] In order to solve this technical problem, the bottom of the reagent tube 1 is provided with a placing structure 4, which consists of two parts: one is a placing opening 40 opened in the bottom of the reagent tube 1 and penetrating through the side wall, and the other is a partition plate 41 arranged inside the reagent tube 1 above the placing opening 40. Through the arrangement of the partition plate 41, the bottom of the reagent tube 1 is divided into upper and lower spaces, the upper layer is used to safely carry the solution, and the lower layer provides a convenient position for the user to easily insert one end of the test box 3 into the reagent tube 1 through the placing opening 40, thereby realizing the stable fixation of the test box 3. Such design greatly simplifies the user's operation process, so that in the process of using the suction device 2 to drop the solution onto the test paper, the user can be more convenient, without worrying about the problem of test box 3 sliding or solution dropping deviation caused by improper operation.

[0038] Although the arrangement of the placing structure 4 facilitates the user in the process of using the suction device 2 to drop the solution onto the test paper of the test box 3, there is still a technical problem in this process: when the user needs to pull out the suction device 2 with the solution from the reagent tube 1, some solution may be attached due to the contact between the components of the suction device 2 and the solution. This attached solution may drop onto the desktop during the pulling out of the suction device 2, thereby causing the user subsequent cleaning trouble, which is obviously not conducive to improving the user's overall experience.

[0039] To solve this technical problem, the present embodiment is provided with a communication structure 5 in the middle of the partition plate 41, the core of which is a connecting hole 50 that penetrates the partition plate 41, allowing the suction pipe 21 to pass through the partition plate 41 when needed. In addition, opposite receiving grooves 51 are also formed on both sides of the inside of the connecting hole 50, and filling structures 6 are arranged in these receiving grooves 51 to ensure that the connecting hole 50 can be effectively closed when the solution is not needed to be output.

[0040] The filling structure 6 consists of two parts: one part is the filling block 60 inserted into the receiving groove 51, which can tightly fit around the connecting hole 50; the other part is the spring 61 arranged in the receiving groove 51, one end of which is fixed inside the receiving groove 51, and the other end is connected with the filling block 60. Through the elastic force of the spring 61, the filling block 60 can be continuously pushed out of the receiving groove 51, so as to ensure that the connecting hole 50 is tightly closed by the filling block 60 in normal state.

[0041] Through such a setting, after the suction device 2 completes the suction of the solution, the user does not need to pull out the suction device 2 from the reagent tube 1. On the contrary, the user can directly make the suction pipe 21 of the suction device 2 pass through the partition plate 41 through the communication hole 11 to spray the solution to the test box 3 located below the partition plate 41. The user only needs to simply place the end of the test paper exposed on the test box 3 in the reagent tube 1 to achieve accurate output of the solution. In this way, the problem of solution dripping during the pulling-out process of the suction device 2 is completely avoided, not only improving the user's experience, but also making the whole process of using the reagent box more convenient.

[0042] At the same time, the setting of the filling structure 6 also ensures that the solution will not be output to the test paper in advance when it is not needed. During the mixing process of the fecal sample and the solution, the spring 61 will push the filling blocks 60 in the two receiving grooves 51 to abut against each other, thereby effectively blocking the connecting hole 50. Only when the user needs to output the solution, by pushing the suction device 2 to make the suction pipe 21 press the filling block 60 to shrink into the receiving groove 51, can the output of the solution to the test paper be realized. Such a setting not only ensures the accuracy of the test, but also avoids unnecessary waste and pollution.

[0043] Although the design of the suction device 2 has effectively avoided the risk of directly pouring the solution on the user's hand, thereby significantly improving the user's experience, in actual operation, the user may still encounter a technical problem when pushing the pull rod 22 to push the excrement sample in the suction pipe 21 into the solution in the reagent tube 1 with the expelled air: the excrement sample in the suction pipe 21 does not always fall completely into the reagent tube 1. If this situation is not noticed by the user, when the solution is subsequently sucked by the suction device 2, the excrement sample that is not dissolved in the solution may be carried by the solution and eventually drop on the test paper of the test box 3. This residue of excrement sample not only may interfere with the accuracy of the test result, but also may mislead the user's judgment.

[0044] To solve this technical problem, the present embodiment is provided with a set of protective devices 7 on the suction pipe 21. This set of protective devices 7 consists of two parts: one is a connecting sleeve 70 that is sleeved on the suction pipe 21; the other is a collection part 71 that is fixedly arranged on the end of the connecting sleeve 70 away from the suction pipe 21, and is specially used for collecting the excrement sample, thereby ensuring the accuracy and integrity of the sample.

[0045] In actual operation, the user first reserves a certain air space in the suction cylinder 20 by pulling the pull rod 22. Then, the connecting sleeve 70 is sleeved on the suction pipe 21, and the required excrement sample is collected by the collection part 71. Next, an appropriate amount of solution is added into the reagent tube 1, and the tube opening of the reagent tube 1 is tightly covered with the cover 10, so as to ensure that the suction device 2 is stably placed in the reagent tube 1. At this time, by gently shaking the reagent tube 1, the solution can be fully mixed with the excrement sample, so as to prepare for the subsequent test.

[0046] When the solution needs to be extracted, the user only needs to push the pull rod 22 again, and the air in the suction cylinder 20 will flow out smoothly through the suction pipe 21. At the same time, this outflowing air also generates a pushing force, so that the connecting sleeve 70 is separated from the suction pipe 21. In this way, the suction pipe 21 can freely suck the solution. Due to the timely separation of the connecting sleeve 70, the excrement sample is firmly left in the reagent tube 1, avoiding recontacting with the solution, thereby effectively preventing the excrement sample from sticking to the inside of the suction pipe 21.

[0047] In addition, when the user needs to perform detection again, the user only needs to simply clean the suction device 2 and the reagent tube 1, and then take a new test box 3 and protective device 7 for replacement. Such a design not only saves the cost and time of the user, but also makes the whole detection process more flexible and convenient.

[0048] Specific implementation process: first, the cover 10 and the suction device 2 inserted on the cover 10 from the reagent tube 1, then pull the pull rod 22 so that the suction cylinder 20 left with air, then the connecting sleeve 70 set on the suction tube 21, and then use the collection part 71 to collect the fecal sample, then add the solution into the reagent tube 1, and then cover the reagent tube 1 with the cover 10 so that the suction device 2 is located in the reagent tube 1, then shake the reagent tube 1 so that the solution and the fecal sample are mixed, then push the pull rod 22 so that the air in the suction cylinder 20 flows out through the suction tube 21, and the air flowing out will push the connecting sleeve 70 off the suction tube 21, so that the suction tube 21 sucks the solution, then pull the pull rod 22, so that the friction block 23 rises along the suction cylinder 20, and the external air is sucked into the suction cylinder 20 through the suction tube 21, and the solution is also brought into the suction tube 21, then push the suction cylinder 20, so that the suction tube 21 is inserted 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 push the pull rod 22, so that the friction block 23 descends along the suction cylinder 20, and the air in the suction cylinder 20 is pressed out, so that the air pressed out pushes the solution in the suction tube 21 to drop on the test paper of the test box 3, and after 15 minutes, the detection result can be observed.

[0049] The embodiments of the specific implementation are the preferred embodiments of the application, and are not limited to the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
