They are particularly suitable for regulatory agencies during on-site enforcement, initial screening of family members for viral infections, and rapid qualitative and quantitative analysis of test cards in small clinics and departments. Existing handheld reagent card analyzers require inserting the reagent card into a slot on the casing, followed by scanning the sampling area of ​​the card using a fluorescent detection device inside the casing to detect the content of specific proteins in the sample. However, in practice, the reagent card may move within the slot, leading to inaccurate test results. Utility Model Content

[0003] The purpose of this invention is to provide a handheld reagent card analyzer, which aims to solve the problem that existing handheld reagent card analyzers are prone to reagent cards becoming loose in the card slot, leading to inaccurate test results.

[0024] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Please refer to the following: Figures 1 to 3 The present invention provides a handheld reagent card analyzer. The handheld reagent card analyzer includes: a housing 1 and a limiting spring 2; a card slot 101 for inserting a reagent card is provided on the side of the housing 1; the limiting spring 2 is installed inside the housing 1 and located on one side of the card slot 101, with one end of the limiting spring 2 extending into the inside of the card slot 101 and abutting against the side of the reagent card.

[0026] This embodiment provides a handheld reagent card analyzer. Compared with the prior art, a limiting spring 2 is installed on one side of the card slot 101. Since one end of the limiting spring 2 extends into the card slot 101, when the reagent card is inserted into the card slot 101, the limiting spring 2 applies a force to the side of the reagent card by its own elasticity, so that the reagent card remains relatively fixed in the card slot 101, thereby avoiding the reagent card from shaking and ensuring the accuracy of the test results.

[0027] In this embodiment, the limiting spring 2 can be located on both sides of the slot 101 or at the bottom of the slot 101.

[0028] In some embodiments, please refer to Figures 1 to 3 The outer shell 1 includes an upper shell 102 and a lower shell 103. The lower shell 103 is detachably mounted on the bottom of the upper shell 102, and a limiting spring 2 is installed inside the lower shell 103. In this embodiment, the lower shell 103 is fixed to the bottom of the upper shell 102 by screws. A slot 101 is formed on the outer side wall of the lower shell 103. Since the limiting spring 2 is mounted on the lower shell 103, it is convenient to assemble the limiting spring 2.

[0029] In some embodiments, please refer to Figure 2 and Figure 3 The limiting spring 2 has a first bent portion 201 and a second bent portion 202 at one end, with the bending directions of the first bent portion 201 and the second bent portion 202 being opposite. The lower shell 103 has a first limiting post 104 and a second limiting post 105, with the first limiting post 104 located at the inner corner of the first bent portion 201 and the second limiting post 105 located at the inner corner of the second bent portion 202. In this embodiment, the limiting spring 2 is a sheet metal part. Both the first bent portion 201 and the second bent portion 202 are located at one end of the limiting spring 2. Because the bending directions of the first bent portion 201 and the second bent portion 202 are opposite, the first bent portion 201 and the second bent portion 202 form a Z-shaped structure. Since the first limiting post 104 is located at the inner corner of the first bend and the second limiting post 105 is located at the inner corner of the second bend 202, the first limiting post 104 and the second limiting post 105 cooperate to restrict the position of the limiting spring 2 in the horizontal direction, thereby fixing the limiting spring 2 on the lower shell 103.

[0030] In some embodiments, please refer to Figure 3 The lower shell 103 is also provided with a third limiting post 106 and a fourth limiting post 107. The third limiting post 106 and the fourth limiting post 107 are located between the first limiting post 104 and the second limiting post 105, and are respectively located on both sides of the length direction of the limiting spring piece 2. The third limiting post 106 and the fourth limiting post 107 are located between the first limiting post 104 and the second limiting post 105, and are respectively arranged on both sides of the length direction of the limiting spring piece 2 and staggered from each other. The third limiting post 106 and the fourth limiting post 107 abut against the side wall of the limiting spring piece 2, thereby preventing the fixing end of the limiting spring piece 2 and the lower shell 103 from bending and deforming under the action of external force.

[0031] In some embodiments, please refer to Figure 4 The handheld reagent card analyzer also includes a support 301, a first guide rod 302, a fluorescence scanner 303, and a drive unit 304. The support 301 is fixedly mounted on the lower shell 103 and located above the card slot 101. The first guide rod 302 and the drive unit 304 are both fixedly mounted on the support 301. The first guide rod 302 is parallel to the length direction of the card slot 101. The fluorescence scanner 303 is mounted on the first guide rod 302 and slides with it. The drive unit 304 drives the fluorescence scanner 303 to reciprocate on the first guide rod 302. The fluorescence scanner 303 is used to scan the sampling area of ​​the reagent card. In this embodiment, the support 301 is fixed inside the lower shell 103 by screws and located directly above the card slot 101. The first guide rod 302 is fixedly mounted horizontally on the bracket 301, and the first guide rod 302 is parallel to the length direction of the card slot 101 (the length direction of the sampling area of ​​the reagent card is consistent with the length direction of the card slot 101). The fluorescence scanning element 303 is slidably mounted on the first guide rod 302. The driving element 304 drives the fluorescence scanning element 303 to reciprocate on the first guide rod 302. Because the range of motion of the fluorescence scanning element 303 is increased, the fluorescence scanning element 303 can be made smaller while ensuring that the entire sampling area of ​​the reagent card can be scanned, thereby saving production costs.

[0032] In some embodiments, please refer to Figure 4 and Figure 5The driving component 304 is a motor. A screw 305 is mounted on the bracket 301, and the screw 305 is parallel to the first guide rod 302. The output shaft of the motor is fixedly connected to the screw 305. A slider 306 is mounted on the screw 305, and the slider 306 is threadedly connected to the screw 305. The screw 305 drives the fluorescent scanning element 303 to move on the first guide rod 302 via the slider 306. In this embodiment, the driving component 304 is a motor, which is fixedly mounted on the bracket 301. The screw 305 is rotatably mounted on the bracket 301, and the screw 305 is parallel to the first guide rod 302. The motor drives the screw 305 to rotate. Since the slider 306 is threadedly connected to the screw 305, while the motor drives the screw 305 to rotate, the slider 306 drives the fluorescent scanning element 303 to reciprocate on the first guide rod 302, thereby achieving a complete scan of the entire sampling area of ​​the reagent card.

[0033] In some embodiments, please refer to Figures 5 to 7 The bracket 301 includes a first base 307 and a second base 308. The first base 307 is fixedly mounted on the lower shell 103, a first guide rod 302 is mounted on the first base 307, and the second base 308 is detachably mounted on the first base 307. A drive member 304 and a screw 305 are both mounted on the second base 308. A support block 309 is provided on one side of the fluorescent scanning element 303, and a slot 310 is provided on the support block 309 for insertion and engagement with the slider 306. In this embodiment, the first base 307 is fixed inside the lower shell 103 with screws, and the second base 308 is fixed to the first base 307 with screws. The first guide rod 302 is fixedly mounted on the first base 307, and the drive member 304 and the screw 305 are both mounted on the second base 308, thereby improving assembly efficiency. The support block 309 is located on the side of the fluorescent scanning element 303 opposite to the first guide rod 302. The slider 306 is directly inserted into the slot 310 on the support block 309, thereby realizing the connection between the slider 306 and the fluorescent scanning element 303.

[0034] In some embodiments, please refer to Figure 5 and Figure 6 The slot 310 is located on the side of the support block 309 facing the screw 305. In this embodiment, since the slot 310 faces the screw 305, when assembling or disassembling the slider 306, it is only necessary to move the second base 308 along the side close to or away from the support block 309, which greatly improves the assembly efficiency.

[0035] In some embodiments, please refer to Figure 6The slot 310 penetrates the support block 309 vertically. A second guide rod 311 is mounted on the second base 308, and the second guide rod 311 is parallel to the first guide rod 302. The second guide rod 311 is slidably engaged with the slider 306. In this embodiment, the slot 310 penetrates the support block 309 vertically to facilitate alignment between the slider 306 and the slot 310. Because the slider 306 is slidably engaged with the second guide rod 311, the stability of the slider 306 during movement is ensured. The second guide rod 311 is slidably engaged with the support block 309, so the second guide rod 311 can support the fluorescent scanning element 303, ensuring a more balanced force on the fluorescent scanning element 303. Since the support block 309 has a notch that matches the second guide rod 311, and this notch is located on the side of the support block 309 facing the screw 305, the second guide rod 311 and the slider 306 can move together horizontally and disengage from the support block 309.

[0036] In some embodiments, please refer to Figure 2 A limit switch 312 is installed at the end of the card slot 101. In this embodiment, the limit switch 312 is fixedly installed at the end of the card slot 101 and is used to control the opening of the motor. When the reagent card is installed in the card slot 101, the reagent card will exert a force on the limit switch 312, and the limit switch 312 will open accordingly. The fluorescent scanning element 303, driven by the driving element 304, scans the sampling area of ​​the reagent card, thereby realizing the automatic scanning function.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
