Description

Technical Field

[0001] This utility model relates to the field of experimental medicine, and more specifically, to a fully automated colloidal gold plate measuring instrument. Background Technology

[0002] Colloidal gold stencils are test strips used for antigen detection, primarily for rapid screening of diseases such as the novel coronavirus and HIV. These stencils utilize the unique properties of colloidal gold particles through a specific chemical reaction to display the test results. Large-scale testing requires the use of specialized instruments for batch processing. The faster and more convenient detection of antigens using colloidal gold stencils has become a hot topic in this field.

[0003] Currently, the detection process of colloidal gold plates mainly relies on manual operation. First, the sample needs to be mixed in a test tube, usually by manually holding the test tube and shaking it to ensure thorough and uniform mixing. Second, the operation of the colloidal gold plate is also mainly manual, including steps such as sample addition, control of reaction time, and result reading.

[0004] The existing technology has the following defects and directions for improvement: (1) When processing the test samples in the test tube, the test tube is usually held manually and shaken to ensure that the sample is fully mixed inside the test tube. However, this operation method not only greatly increases the labor intensity of the staff, but also has low mixing efficiency, which has an adverse effect on the overall processing effect. (2) In addition, the operation of colloidal gold plates mainly relies on manual operation. This process is not only time-consuming and laborious, but also requires the operator to check the experimental results at regular intervals. This requirement increases the complexity of the operation and is likely to cause the result to be checked beyond the time limit. Utility Model Content

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a fully automatic colloidal gold plate analyzer. Through a mixing mechanism, the drive motor is activated, causing the drive screw rod to rotate. This rotation, through the threaded action and the limiting action of the moving groove, drives a moving screw block in linear motion. The linear motion of the moving screw block drives a moving fixed block in linear motion, which in turn drives a moving gear shaft in linear motion. This linear motion of the moving fixed block, in turn, drives the moving gear shaft to rotate through meshing with a transmission gear plate. The rotation of the moving gear shaft drives the storage bin to rotate, which in turn mixes the internal sample, facilitating subsequent measurements and saving significant measurement time.

[0006] To achieve the above objectives, a fully automatic colloidal gold plate analyzer includes: a detection platform, wherein a moving groove is provided at the top of the center of the detection platform, the top of the left side of the detection platform is fixedly connected to the bottom of two limiting plates respectively, a transmission gear plate is fixedly connected to the top of the detection platform near the moving groove, a reading plate is fixedly connected to the top of the right side of the detection platform, support frames are fixedly connected to the top of both sides of the detection platform, a barcode scanner is fixedly connected to the bottom of the left side of the support frame, and a sampler is slidably connected to the bottom of the right side of the support frame; a mixing mechanism located at the top of the detection platform, the mixing mechanism including a motor mounting base fixedly connected to the left side of the detection platform, and a drive motor is bolted to the top of the motor mounting base; and an auxiliary mechanism located at the top of the right side of the detection platform, the auxiliary mechanism including an auxiliary fixing plate fixedly connected to the top of the detection platform.

[0010] As a preferred technical solution of this utility model, an auxiliary connecting rod extends through one side of the auxiliary fixing plate.

[0015] (2) The auxiliary threaded rod of this utility model rotates through the thread action to drive the auxiliary threaded rod to move upward within the height range of the transmission gear plate.

Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figure 1-6 As shown, this embodiment proposes a fully automatic colloidal gold plate analyzer, including a detection platform 1, a moving groove 2 provided at the top of the middle part of the detection platform 1, the top of the left side of the detection platform 1 being fixedly connected to the bottom of two limiting plates 3 respectively, a transmission gear plate 4 being fixedly connected to the top of the detection platform 1 near the moving groove 2, a reading plate 5 being fixedly connected to the top of the right side of the detection platform 1, support frames 6 being fixedly connected to the top of both sides of the detection platform 1, a barcode scanner 7 being fixedly connected to the bottom of the left side of the support frame 6, and a sampler 8 being slidably connected to the bottom of the right side of the support frame 6; a mixing mechanism located at the top of the detection platform 1, the mixing mechanism including a motor mounting base 9 fixedly connected to the left side of the detection platform 1, and a drive motor 10 being bolted to the top of the motor mounting base 9; an auxiliary mechanism located at the top of the right side of the detection platform 1, the auxiliary mechanism including an auxiliary fixing plate 17 fixedly connected to the top of the detection platform 1, the sampler 8 including a sampling head, a sampling mounting plate and a sampling hydraulic cylinder, and the barcode scanner 7 including a scanning port and a scanning linkage.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, the output end of the drive motor 10 is fixedly connected to the drive threaded rod 11, and the outer wall of the drive threaded rod 11 is threadedly connected to the inner wall of the movable threaded block 12. The outer wall of the movable threaded block 12 is slidably connected to the inner wall of the movable groove 2. When the drive motor 10 is started, the drive motor 10 rotates and drives the drive threaded rod 11 to rotate. The rotation of the drive threaded rod 11 drives the movable threaded block 12 to move linearly through the thread action and the limiting action of the movable groove 2.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, the mixing mechanism also includes a movable fixed block 13 fixedly connected to the top of the movable threaded block 12, and the top of the movable fixed block 13 is rotatably connected to the bottom of the movable gear shaft 15. A storage box 16 is fixedly connected to the top of the movable gear shaft 15. A QR code display panel with the same number of samples is provided on the top of the storage box 16. The linearly moving movable threaded block 12 drives the movable fixed block 13 to move linearly. The linearly moving fixed block 13 drives the movable gear shaft 15 to move linearly. The linearly moving movable gear shaft 15 drives the movable gear shaft 15 to rotate through meshing with the transmission gear plate 4. The rotation of the movable gear shaft 15 drives the storage box 16 to rotate. The rotation of the storage box 16 can mix the samples inside, which is convenient for subsequent measurement.

[0030] like Figure 2 , Figure 3 and Figure 4As shown, the outer wall of the movable gear shaft 15 is meshed with one side of the transmission gear plate 4, and the inner wall of the movable gear shaft 15 is fixedly connected to the outer wall of the top end of the auxiliary threaded rod 14. The length of the auxiliary threaded rod 14 is less than the height of the transmission gear plate 4. The rotation of the movable gear shaft 15 drives the auxiliary threaded rod 14 to rotate. The rotation of the auxiliary threaded rod 14 drives the auxiliary threaded rod 14 to move upward within the height range of the transmission gear plate 4 through the thread action. The upward movement of the auxiliary threaded rod 14 drives the storage box 16 to move upward through the movable gear shaft 15, which can facilitate the sampler 8 to take samples and avoid sampling failure due to uneven liquid levels in the sample volume.

[0031] like Figure 5 and Figure 6 As shown, an auxiliary connecting rod 18 extends through one side of the auxiliary fixing plate 17.

[0032] like Figure 5 and Figure 6 As shown, one end of the auxiliary connecting rod 18 is fixedly connected to one side of the auxiliary arc plate 19, and an auxiliary spring 20 is installed on the outer wall of the auxiliary connecting rod 18 between the auxiliary arc plate 19 and the auxiliary fixed plate 17. The other end of the auxiliary connecting rod 18 is fixedly connected to the auxiliary baffle 21. After the storage box 16 rotates and mixes, the moving gear shaft 15 disengages from the transmission gear plate 4, and the storage box 16 continues to move linearly. When the storage box 16 moves linearly to the auxiliary arc plate 19, it can drive the auxiliary arc plate 19 to move linearly. The linear movement of the auxiliary arc plate 19 is buffered by the auxiliary spring 20. The continued movement of the storage box 16 can be kept stable by the arc surface of the auxiliary arc plate 19, so as to avoid the storage box 16 deflecting during sampling, causing the sampler 8 to hit the storage box 16 and damage the sampler 8.

[0033] There are two sets of auxiliary arc plates and auxiliary springs, and the two sets of auxiliary arc plates and auxiliary springs are symmetrically installed on both sides of the drive threaded rod. This ensures that the force on both sides of the storage box 16 is uniform and stable.

[0034] Specifically, in use of this fully automatic colloidal gold plate analyzer: after the test tube is placed, the drive motor 10 is started first. The drive motor 10 rotates, driving the drive threaded rod 11 to rotate. The rotation of the drive threaded rod 11, through the thread action and the limiting action of the moving groove 2, drives the moving threaded block 12 to move linearly. The linearly moving moving threaded block 12 drives the moving fixed block 13 to move linearly. The linearly moving fixed block 13 drives the moving gear shaft 15 to move linearly. The linearly moving moving gear shaft 15, through meshing with the transmission gear plate 4, drives the moving gear shaft 15 to rotate. The rotation of the moving gear shaft 15 drives the storage box 16 to rotate. The rotation of the storage box 16 can mix the sample inside, facilitating subsequent measurement. The rotation of the moving gear shaft 15 drives the auxiliary threaded rod 14 to rotate. The rotation of rod 14 drives the auxiliary threaded rod 14 to move upward within the height range of the transmission gear plate 4 through the threaded action. The upward movement of the auxiliary threaded rod 14 drives the storage box 16 to move upward through the moving gear shaft 15, which facilitates sampling by the sampler 8 and avoids sampling failure due to uneven liquid levels in the sample volume. After the storage box 16 rotates and mixes, the moving gear shaft 15 disengages from the transmission gear plate 4, and the storage box 16 continues to move linearly. When the storage box 16 moves linearly to the auxiliary arc plate 19, it can drive the auxiliary arc plate 19 to move linearly. The linear movement of the auxiliary arc plate 19 is buffered by the auxiliary spring 20. The continued movement of the storage box 16 can be kept stable by the arc surface of the auxiliary arc plate 19, avoiding the storage box 16 from deflecting during sampling and causing the sampler 8 to collide with the storage box 16, which would damage the sampler 8.
