Description
Technical Field
[0001] This utility model relates to the field of detection instrument technology, and in particular to a handheld poison reagent card detector. Background Technology
[0002] A handheld poison test kit is a portable, rapid device for detecting poisons, primarily used for on-site qualitative or quantitative analysis of various poisons. This instrument typically uses test cards as the detection medium, identifying specific poisons through chemical or biological reactions. It is widely used in forensic medicine for detecting drugs and toxic substances, in environmental monitoring for identifying pollutants in soil and water, and in food safety for testing pesticide residues and additives in food.
[0003] In existing technologies, handheld poison reagent card detectors generally rely on reagent cards as the core detection element when performing detection tasks. However, once the device reacts during the reading of the reagent card, the staff must properly preserve the relevant reagent card so that it can be taken back to the laboratory for more detailed testing and in-depth analysis. This not only requires the staff to have appropriate storage containers on hand at all times to prevent the reagent card from being contaminated or damaged, but also increases the complexity and burden of their work, because they need to pay extra attention to the integrity and stability of the reagent card to ensure the accuracy of subsequent tests. In addition, the storage and carrying of reagent cards also brings additional logistical challenges to on-site operations, affecting work efficiency. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a handheld poison reagent card detector.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a handheld poison reagent card detector, including a handheld device. One side of the handheld device has an inner groove, the inner wall of which is fixed with a spring protrusion. A round-headed plate is fixed to the bottom of the inner groove. A thin shaft is rotatably connected to the inner wall of the inner groove. One end of the thin shaft is rotatably connected to one side of the round-headed plate. A slot is formed in a circumferential array on the circumferential surface of the thin shaft. The inner wall of the slot is nested with the surface of the spring protrusion. A dial is fixed to the circumferential surface of the thin shaft. An installation shaft is fixed to the circumferential surface of the thin shaft. A test strip storage tube is detachably connected to the circumferential array on the installation shaft. A rubber disc is glued to one end of the test strip storage tube. A slot is formed on the surface of the rubber disc. In the prior art, handheld poison reagent card detectors generally rely on the reagent card as the core detection element when performing detection tasks. However, if the device reacts during the reading of the reagent card, the operator must... Properly storing the reagent cards for later laboratory testing and analysis requires staff to have appropriate storage containers readily available to prevent contamination or damage. This also increases the complexity and burden of their work, as extra care must be taken to ensure the integrity and stability of the reagent cards to guarantee the accuracy of subsequent tests. Furthermore, the storage and transport of reagent cards presents additional logistical challenges for on-site operations, impacting work efficiency. To address these issues, this invention employs a test strip storage tube. When staff need to store test strips, they simply insert the strip into the slot of the storage tube for temporary storage. Rotating the dial adjusts the tube's position, simultaneously engaging the spring tab in the next slot, providing feedback to the user. Upon returning to the laboratory, staff can remove the storage tube for further testing, thus improving the user experience.
[0006] Preferably, the handheld device has a slot on one side, a limit groove on the inner wall of the slot, a test strip box slidably connected to the inner wall of the slot, a shaft fixed to the test strip box, rotating caps rotatably connected to both ends of the shaft, a movable plate fixed to the circumference of the rotating caps, a retaining spring on the circumference of the shaft, one end of the retaining spring fixed to the movable plate, the other end of the retaining spring fixed to the circumference of the shaft, a limit strip fixed to the surface of the movable plate, and a pinch plate fixed to one end of the movable plate. In the prior art, when using a handheld poison reagent card detector for on-site testing, disposable reagent cards are indispensable. These reagent cards usually need to be prepared and carried by the staff before the task. However, this process has some operational inconveniences and risks. Firstly, Since reagent cards are consumables separate from the testing instrument, staff may forget to bring enough when busy or unprepared, resulting in the inability to conduct tests upon arrival and delaying the testing process. Furthermore, even if they remember to bring the reagent cards, staff must be extremely careful during transport, as any accidental squeezing, bending, or dropping can damage them, affecting the accuracy and reliability of the tests. To address these issues, this invention uses a test strip box. Before going out, staff place test strips into the box, then pinch the upper and lower levers to bring the movable plate closer to the center, inserting it into the box slot. Releasing the lever causes the spring to return, locking the movable plate's limiting strip into the limiting slot, thus improving the user experience.
[0007] Preferably, the handheld device is fixed with feet at the bottom. In the prior art, the detector often comes into direct contact with the surface it is placed on, such as a desktop or other hard surface, which may cause wear or scratches on the surface of the device, affecting the appearance and service life of the device. To address this problem, the present invention uses feet to prevent the device from coming into direct contact with the desktop or the device, thereby improving the service life of the device.
[0008] Preferably, the bottom of the support leg is glued with a rubber pad to increase friction, prevent displacement, and improve user experience.
[0009] Preferably, the insertion slit height is equal to the reagent card thickness to increase the friction between them, prevent the test strip from falling out, and improve the stability of the equipment.
[0010] Preferably, the dial wheel has a circumferential array of friction-enhancing grooves to increase the friction between the component and the finger, thereby improving the user experience.
[0011] Preferably, the edges of the friction-enhancing groove are rounded to prevent scratches on the user and improve the user experience.
[0012] Beneficial effects:
[0013] 1. In existing technologies, handheld poison reagent card detectors generally rely on reagent cards as the core detection element when performing detection tasks. However, once a reaction occurs during the reading of a reagent card, staff must properly preserve the relevant reagent card to bring it back to the laboratory for more detailed testing and in-depth analysis. This not only requires staff to always have appropriate storage containers on hand to prevent reagent cards from being contaminated or damaged, but also increases the complexity and burden of their work, as they need to pay extra attention to the integrity and stability of the reagent cards to ensure the accuracy of subsequent tests. In addition, the storage and carrying of reagent cards also brings additional logistical challenges to on-site operations, affecting work efficiency. To address these issues, this utility model solves the problem by installing a test strip storage tube. When staff need to store test strips, they insert the test strip into the slot of the test strip storage tube for temporary storage. Then, they rotate the dial to adjust the position of the test strip storage tube, while simultaneously moving the spring protrusion into the next slot to provide feedback to the user. When staff return to the laboratory, they can remove the test strip storage tube for further testing, thereby improving the user experience.
[0014] 2. In existing technologies, disposable reagent cards are essential for on-site testing using handheld poison reagent card detectors. These cards typically need to be prepared and carried by staff before the mission. However, this process presents some operational inconveniences and risks. First, since reagent cards are consumables separate from the detector, staff may forget to bring enough cards when busy or unprepared, resulting in the inability to conduct tests upon arrival and delaying the testing process. Second, even if staff remember to bring the reagent cards, they must be extremely careful during transport, as any accidental squeezing, bending, or dropping can damage the cards, affecting the accuracy and reliability of the test. To address these issues, this invention solves the problem by installing a test strip box. Before carrying the device, staff place test strips into the box, then pinch the upper and lower levers to bring the movable plate closer to the center, inserting it into the slot. Releasing the lever causes the spring to return, locking the limiting strip of the movable plate into the limiting slot, thus improving the user experience.
[0015] 3. In the prior art, the testing instrument often comes into direct contact with the surface it is placed on, such as a desktop or other hard surface, which may cause wear or scratches on the surface of the equipment, affecting the appearance and service life of the equipment. In order to solve this problem, this utility model adopts the method of installing support feet, which prevents the equipment from directly contacting the desktop or the equipment, thereby improving the service life of the equipment.

[0025] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:
[0028] Reference Figure 1-7A handheld poison reagent card detector includes a handheld device 1. One side of the handheld device 1 has an inner groove 101. A spring protrusion 301 is fixed to the inner wall of the inner groove 101. A round-head plate 106 is fixed to the bottom of the inner groove 101. A thin shaft 102 is rotatably connected to the inner wall of the inner groove 101. One end of the thin shaft 102 is rotatably connected to one side of the round-head plate 106. A circumferential array of slots 3 is formed on the circumferential surface of the thin shaft 102. The inner wall of the slots 3 is nested within the surface of the spring protrusion 301. A dial 105 is fixed, and a mounting shaft 103 is fixed to the circumference of a thin shaft 102. A test strip reservoir 104 is detachably connected to the circumference of the mounting shaft 103 in a circular array. A rubber disc 107 is glued to one end of the test strip reservoir 104. A slot 108 is formed on the surface of the rubber disc 107. Handheld poison reagent card detectors generally rely on reagent cards as the core detection element when performing detection tasks. However, if the device reacts during the reagent card reading process, staff... The reagent cards must be properly stored to facilitate their return to the laboratory for more detailed testing and in-depth analysis. This not only requires staff to always have appropriate storage containers on hand to prevent contamination or damage to the reagent cards, but also increases the complexity and burden of their work, as they need to pay extra attention to the integrity and stability of the reagent cards to ensure the accuracy of subsequent tests. Furthermore, the storage and transport of reagent cards also brings additional logistical challenges to on-site operations, affecting work efficiency. A solution is found by installing a test strip storage tube 104. When staff need to store test strips, they insert the test strip into the slot 108 of the test strip storage tube 104 for temporary storage. Then, rotating the dial 105 adjusts the position of the test strip storage tube 104, simultaneously moving the spring tab 301 into the next slot 3, providing feedback to the user. When staff return to the laboratory, they can remove the test strip storage tube 104 for further testing, improving the user experience. The height of the slot 108 is equal to the thickness of the reagent card, increasing the friction between them, preventing the test strip from falling out, and improving equipment stability. The dial 105 has a circumferential array of friction-enhancing grooves 109 to increase the friction between the components and fingers, thus improving the user experience. The edges of the friction-enhancing grooves 109 are rounded to prevent scratches to the user, further enhancing the user experience.
[0029] The handheld device 1 has a slot 2 on one side, with a limit groove 201 on the inner wall of the slot 2. A test strip box 202 is slidably connected to the inner wall of the slot 2. A shaft 203 is fixed to the test strip box 202. Rotating caps 204 are rotatably connected to both ends of the shaft 203. A movable plate 206 is fixed to the circumference of the rotating caps 204. A retaining spring 205 is provided on the circumference of the shaft 203. One end of the retaining spring 205 is fixed to the movable plate 206, and the other end is fixed to the circumference of the shaft 203. A limit strip 207 is fixed to the surface of the movable plate 206, and a pinch plate 208 is fixed to one end of the movable plate 206. When using a handheld poison reagent card detector for on-site testing, disposable reagent cards are essential. These reagent cards usually need to be prepared and carried by the staff before the task. However, this process has some operational inconveniences. Regarding the risks, firstly, since reagent cards are consumables independent of the testing instrument, staff may forget to bring enough reagent cards when busy or unprepared, resulting in the inability to conduct tests upon arrival and delaying the testing process. Secondly, even if they remember to bring reagent cards, staff must be extra careful during transport, as any unintentional squeezing, bending, or dropping can damage the reagent cards, thus affecting the accuracy and reliability of the test. The solution is to install a test strip box 202. Before going out, staff can place test strips into the test strip box 202, then pinch the upper and lower pinch plates 208 to bring the movable plate 206 close to the center, insert it into the box slot 2, and then release. The retaining spring 205 rebounds, causing the limiting strip 207 of the movable plate 206 to engage with the limiting slot 201, thereby improving the user experience. The handheld device 1 is equipped with a fixed support foot 4 at its bottom. Since the detector frequently comes into direct contact with surfaces such as desktops or other hard surfaces, this can cause wear or scratches, affecting the device's appearance and lifespan. The support foot 4 solves this problem by preventing direct contact between the device and the desktop, thus extending its lifespan. Rubber pads are glued to the bottom of the support foot 4 to increase friction, prevent misalignment, and improve the user experience.
[0030] The working principle of this utility model is as follows: When the staff needs to store the test strips, they insert the test strips into the slot 108 of the test strip storage tube 104, so that the test strips are temporarily stored. Then, they rotate the dial 105 to adjust the position of the test strip storage tube 104, and at the same time, the spring protrusion 301 enters the next slot 3 to give feedback to the user. When the staff returns to the laboratory, they can remove the test strip storage tube 104 for further testing. Before the staff goes out to take the test strips, they put the test strips into the test strip box 202, and then pinch the upper and lower pinch plates 208 to make the movable plate 206 close to the center. After inserting it into the box slot 2, they release their hands, and the retaining spring 205 rebounds, causing the limiting strip 207 of the movable plate 206 to be inserted into the limiting slot 201.
[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
