Description

Technical Field

[0001] The utility model relates to the technical field of medical detection, in particular to a Helicobacter pylori reagent detection card. Background Art

[0002] Helicobacter pylori is a common digestive tract pathogen that is associated with a variety of gastrointestinal diseases, such as chronic gastritis, gastric ulcers and even gastric cancer. Therefore, timely and accurate detection of infection with this bacterium is crucial for the prevention and treatment of the disease. Currently, there are a variety of Helicobacter pylori detection methods to choose from, including carbon 13 or carbon 14 breath tests, serological tests, and endoscopic biopsy. Among them, the breath test is the most commonly used non-invasive detection method, which is simple, fast and highly accurate. When conducting a breath test, a Helicobacter pylori reagent test card is required.

[0003] When conducting a breath test, you need to blow accurately according to the doctor's instructions. Generally, the blowing time lasts about 3 minutes, until the visible window turns completely yellow. During this period, you can breathe, but inhaling is strictly prohibited. The existing Helicobacter pylori reagent detection card used for breath testing does not have corresponding protection measures to prevent patients from inhaling when breathing. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a Helicobacter pylori reagent detection card to solve the technical problem that the existing Helicobacter pylori reagent detection card has no corresponding protection measures to prevent patients from inhaling when in use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a Helicobacter pylori reagent detection card, comprising a detection card body, a gas one-way flow mechanism is arranged on one side of the detection card body, the gas one-way flow mechanism comprises a vent, a sleeve and an exhalation nozzle, the interior of the sleeve is separated into a first cavity and a second cavity by a partition, a connecting rod is arranged on one side of the exhalation nozzle, a cross bar is arranged on the inner side of the connecting rod, a blocking plate is arranged at one end of the cross bar, a movable seat is arranged on the side of the blocking plate away from the cross bar, a spring is arranged on the side of the movable seat away from the blocking plate, and a fixed base is arranged on the side of the spring away from the movable seat.

[0006] By adopting the above technical solution, in the Helicobacter pylori reagent test card, the gas unidirectional flow mechanism realizes the unidirectional flow and automatic sealing functions of the gas by setting components such as a spring, a movable seat, a sealing plate and an exhalation nozzle, thereby ensuring that the gas can only enter the test card from the exhalation nozzle and will not flow out in the opposite direction.

[0007] Furthermore, the vent hole is provided on the detection card body, and the vent hole is communicated with the first cavity and the detection card body.

[0008] By adopting the above technical solution, the provision of the vent hole can connect the first cavity and the detection card body, ensuring that the gas can smoothly enter the detection area in the detection card body.

[0009] Furthermore, a sealing opening is provided on the partition, and the first cavity is connected with the second cavity through the sealing opening.

[0010] By adopting the above technical solution and controlling the opening and closing of the sealing port, the one-way flow of gas is achieved, thereby ensuring the purity of the detection environment.

[0011] Furthermore, the movable seat is a truncated cone structure, and the size of the movable seat is smaller than the size of the first cavity.

[0012] By adopting the above technical solution and setting the movable seat cone structure, the airflow blown out by the patient flows along the outer wall of the movable seat when entering the first cavity, avoiding directly entering the first cavity, thereby intercepting the moisture in the airflow blown out by the patient to a certain extent.

[0013] Furthermore, the fixed base is fixedly connected to the spring, the spring is fixedly connected to the movable seat, the movable seat is fixedly connected to the blocking plate, and the blocking plate is adapted to the blocking port.

[0014] By adopting the above technical solution, the connection method between the fixed base, the spring, the movable seat and the sealing plate ensures the stability and reliability of the gas one-way flow mechanism during operation.

[0015] Furthermore, the blocking plate is fixedly connected to the cross bar, and the cross bar is fixedly connected to the exhalation nozzle via a connecting rod.

[0016] By adopting the above technical solution, it is ensured that the blocking plate can move accurately when the exhalation nozzle is pushed, thereby improving the response speed of the gas unidirectional flow mechanism.

[0017] Furthermore, the exhalation nozzle is a hollow frustum structure with two sides open, and the inner side of the exhalation nozzle is a flexible structure.

[0018] By adopting the above technical solution and the special structure of the exhalation nozzle, when the patient pushes the exhalation nozzle, it can smoothly fit tightly against the sleeve.

[0019] Furthermore, a plurality of connecting rods are provided, and the plurality of connecting rods are arranged in a circle.

[0020] By adopting the above technical solution and the setting of the connecting rod, the cross bar can be pushed smoothly when the exhalation nozzle is pushed.

[0021] Furthermore, a visual window is provided on one side of the top of the detection card body, and a tearable film is provided on the other side of the top of the detection card body.

[0022] By adopting the above technical solution, the visual window allows patients to monitor in real time whether the exhaled volume meets the standard during exhaled breath collection.

[0023] Furthermore, the tearable film is bonded to the detection card body, and an extension portion is provided on one side of the tearable film.

[0024] By adopting the above technical solution, the tearable film is bonded to the detection card body, ensuring its firmness before use.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] The utility model realizes the one-way flow and automatic sealing function of gas by arranging a spring, a movable seat, a sealing plate and an exhalation nozzle. This design ensures that during the detection process, the gas can only enter the detection card from the exhalation nozzle and will not flow out in the opposite direction when the patient is ventilating, which effectively avoids the risk of patient back-inhalation, greatly improving the convenience and safety of the detection. At the same time, by ensuring the one-way flow of gas, the entry of external air or pollutants is avoided, the purity of the detection environment is maintained, thereby improving the accuracy of the detection.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0033] The following describes an embodiment of the utility model based on its overall structure.

[0034] Embodiment 1:

[0035] A Helicobacter pylori reagent detection card, such as Figure 1-Figure 4 As shown, it includes a test card body 1, a gas unidirectional flow mechanism 4 is arranged on one side of the test card body 1, the gas unidirectional flow mechanism 4 includes a vent 401, a sleeve 402 and an exhalation nozzle 412, the interior of the sleeve 402 is separated into a first cavity 408 and a second cavity 409 by a partition 407, a connecting rod 411 is arranged on one side of the exhalation nozzle 412, a cross bar 410 is arranged on the inner side of the connecting rod 411, a blocking plate 406 is arranged on one end of the cross bar 410, a moving seat 405 is arranged on the side of the blocking plate 406 away from the cross bar 410, a spring 404 is arranged on the side of the moving seat 405 away from the blocking plate 406, and a fixed base 403 is arranged on the side of the spring 404 away from the moving seat 405. In the Helicobacter pylori reagent test card, the gas unidirectional flow mechanism 4 Structure 4 realizes the one-way flow and automatic sealing function of gas by setting components such as spring 404, movable seat 405, sealing plate 406 and exhalation nozzle 412, ensuring that gas can only enter the test card from the exhalation nozzle 412 and will not flow out in the opposite direction. When the patient stops blowing or needs to breathe, the exhalation nozzle 412 is removed, and the spring 404 will use its own elastic force to push the movable seat 405 and the sealing plate 406 back to the original position, automatically closing the sealing port, which greatly improves the convenience and safety of the test. At the same time, by ensuring the one-way flow of gas, the entry of external air or pollutants is avoided, the purity of the test environment is maintained, thereby improving the accuracy of the test. In addition, the patient only needs to align his mouth with the exhalation nozzle 412 and push it hard to start the test, which is simple and intuitive to operate.

[0036] See also Figure 3 , Figure 4 The vent hole 401 is provided on the detection card body 1, and the vent hole 401 is connected with the first cavity 408 and the detection card body 1. The setting of the vent hole 401 can connect the first cavity 408 and the detection card body 1, ensuring that the gas can smoothly enter the detection area in the detection card body 1, thereby improving the detection efficiency. Meanwhile, the reasonable vent hole 401 helps to maintain the gas balance inside the detection card and prevents the pressure change caused by the gas accumulation.

[0037] See also Figure 3 , Figure 4A sealing port is provided on the partition 407, and the first cavity 408 is connected with the second cavity 409 through the sealing port. By opening and closing the sealing port, the one-way flow of gas is realized, and the purity of the detection environment is ensured. When the sealing port is opened, the first cavity 408 and the second cavity 409 remain connected, and the gas blown into the second cavity 409 by the patient can smoothly enter the first cavity 408 and enter the detection card body 1 through the vent 401.

[0038] See also Figure 3 , Figure 4 The movable seat 405 is a truncated cone structure, and the size of the movable seat 405 is smaller than the size of the first cavity 408. The setting of the truncated cone structure of the movable seat 405 enables the airflow blown out by the patient to flow along the outer wall of the movable seat 405 when entering the first cavity 408, avoiding directly entering the first cavity 408, thereby intercepting the moisture in the airflow blown out by the patient to a certain extent. The selection of the size of the movable seat 405 ensures that the movable seat 405 will not collide with the inner wall of the first cavity 408 during the movement, ensuring the smooth passage of the airflow and the smooth operation of the gas one-way flow mechanism 4.

[0039] See also Figure 3 , Figure 4 The fixed base 403 is fixedly connected to the spring 404, the spring 404 is fixedly connected to the movable seat 405, the movable seat 405 is fixedly connected to the sealing plate 406, the sealing plate 406 is adapted to the sealing port, and the connection mode among the fixed base 403, the spring 404, the movable seat 405 and the sealing plate 406 ensures the stability and reliability of the gas one-way flow mechanism 4 during operation, and at the same time, the close connection between the various components ensures that the sealing port can be quickly and accurately closed when needed, and the sealing plate 406 has a high degree of adaptability to the sealing port, so that the sealing port can be tightly sealed by the sealing plate 406.

[0040] See also Figure 2 , Figure 3 , Figure 4 The blocking plate 406 is fixedly connected to the cross bar 410, and the cross bar 410 is fixedly connected to the exhalation nozzle 412 through the connecting rod 411, ensuring that the blocking plate 406 can move accurately when the exhalation nozzle 412 is pushed, thereby improving the response speed of the gas one-way flow mechanism 4. The exhalation nozzle 412 is pushed during detection and released during ventilation, thereby completing the exhalation test without back-inhalation.

[0041] See also Figure 1 , Figure 2 , Figure 3The exhalation nozzle 412 is a hollow cone structure with open sides. The inner side of the exhalation nozzle 412 is a flexible structure. The special structure of the exhalation nozzle 412 allows the patient to smoothly adhere to the sleeve 402 when pushing the exhalation nozzle 412, and the gas can smoothly enter the second cavity 409. The flexible structure of the exhalation nozzle 412 further ensures the comfort and stability of the patient during use.

[0042] See also Figure 2 , Figure 3 , Figure 4 A plurality of connecting rods 411 are provided, and the plurality of connecting rods 411 are arranged in a circle. The arrangement of the connecting rods 411 can smoothly push the cross bar 410 when pushing the exhalation nozzle 412. The plurality of connecting rods 411 arranged in a circle make the pushing of the exhalation nozzle 412 more stable, while increasing the strength and stability of the mechanism and improving durability.

[0043] Embodiment 2:

[0044] See also Figure 1 , Figure 2 , Figure 3 A visible window 3 is provided on one side of the top of the test card body 1, and a tearable film 2 is provided on the other side of the top of the test card body 1. The visible window 3 allows the patient to monitor in real time whether the exhaled volume meets the standard during exhaled breath collection. The setting of the tearable film 2 makes it easy to tear it off and expose the part that needs to be tested to medical staff.

[0045] See also Figure 1 , Figure 2 , Figure 3 The tearable film 2 is bonded to the detection card body 1, and an extension portion is provided on one side of the tearable film 2. The tearable film 2 is bonded to the detection card body 1 to ensure its firmness before use. The extension portion design makes it easy for users to tear off the tearable film 2, thereby improving the convenience of use.

[0046] The implementation principle of the utility model is as follows: first, the patient aligns his mouth with the exhalation nozzle 412, and pushes the exhalation nozzle 412 with force to make it fit tightly with the sleeve 402. After the exhalation nozzle 412 is pushed, the cross bar 410 is pushed to move, so that the blocking plate 406 leaves the blocking port, and further pushes the movable seat 405 to squeeze the spring 404 so that it is forced to contract, and at this time the blocking port is opened; secondly, the patient starts to blow air, and the blown airflow passes through the exhalation nozzle 412 into the second cavity 409, passes through the blocking port, flows along the outer wall of the movable seat 405, and enters the first cavity 408, and then enters the detection card body 1 through the vent 401; when the patient needs to breathe, he only needs to move his mouth away from the exhalation nozzle 412 first, and then breathe. When the mouth is moved away from the exhalation nozzle 412, the spring 404 is no longer squeezed, so under the action of the elastic restoring force, the movable seat 405 is pushed to move in the reverse direction, and the blocking plate 406 is moved back to the blocking port. The first cavity 408 and the second cavity 409 are no longer connected, thereby effectively preventing the gas entering the detection card body 1 from flowing out in the reverse direction, thereby preventing the patient from inhaling when breathing.

[0047] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
