[0001] This utility model relates to the field of semen quality analysis technology, specifically to a sample pretreatment structure for a concentric circle sperm quality analyzer. Background Technology
[0002] A sperm quality analyzer is a core medical device used to assess male reproductive health. Through microscopic imaging, computer image processing, and artificial intelligence algorithms, it performs automated and standardized analysis of key parameters such as sperm count, motility, morphology, and movement trajectory, providing a scientific basis for the clinical diagnosis of male infertility and the assessment of fertility.
[0003] In traditional techniques, a set of operating tables is set up, and sampling cups are placed inside the operating tables for analysis and testing. However, when semen remains still for a long time, sedimentation will occur, and it needs to be mixed. Therefore, a socket is set inside the operating table to place the sampling cups. However, in practice, the internal size of the socket is set in advance, and the volume of the sampling cups varies, making it impossible to fix sampling cups of any size.
[0004] Therefore, it is particularly important to improve the existing concentric circle sperm quality analyzer sample pretreatment structure, design a novel concentric circle sperm quality analyzer sample pretreatment structure to solve the above-mentioned technical defects, and improve the overall practicality of the concentric circle sperm quality analyzer sample pretreatment structure. Summary of the Invention

When using the sample pretreatment structure, pressure is applied to the contact plate by the sampling cup, and then the contact plate squeezes and swings the clamping rod to clamp sampling cups of different sizes, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] Example: Please refer to Figures 1-5. This utility model provides a technical solution:
[0026] A sample pretreatment structure for a concentric circle sperm quality analyzer includes a monitor 1. A stepper motor is fixedly connected to the bottom of the monitor 1. A connecting plate 2 is fixedly connected to the output end of the stepper motor. A first ring 3, a second ring 4, and a third ring 5 are fixedly connected to the top of the connecting plate 2. An insertion hole 301 is provided inside the first ring 3. A sampling cup 6 is slidably connected to the insertion hole 301. A fixing cylinder 7 is fixedly connected to the bottom of the insertion hole 301. Placement slots 8 are symmetrically provided on the outer side of the fixing cylinder 7. An installation plate 9 is fixedly connected to the inner side of the fixing cylinder 7. A connecting slot 10 is provided inside the installation plate 9. The placement slot 8 and the connecting plate 9 are connected to the sampling cup 6. The interiors of the receiving groove 10 are interconnected. A clamping rod 11 is rotatably connected inside the receiving groove 10. By placing the semen inside the sampling cup 6 and then inserting the sampling cup 6 into the insertion hole 301, the stepper motor is driven to rotate the connecting plate 2, causing the first ring 3, the second ring 4, and the third ring 5 to rotate synchronously. This causes the semen inside the sampling cup 6 to shake, achieving a centrifugal mixing effect. At the same time, when the sampling cup 6 is inserted into the insertion hole 301, the clamping rod 11 is rotated, and then the clamping rod 11 swings inside the receiving groove 10 to fix the sampling cup 6.
[0027] Furthermore, in this embodiment, a slot is provided in the middle of the mounting plate 9, and a disc 12 is fixedly connected inside the slot. A limiting post 13 is slidably connected inside the disc 12. A contact plate 14 is fixedly connected to the top of the limiting post 13. A first spring 15 is sleeved on the bottom of the contact plate 14 and outside the limiting post 13. A clamping rod 11 extends between the disc 12 and the contact plate 14. A pressing block 16 is fixedly connected to the end of the clamping rod 11 away from the disc 12. A constant temperature heating plate is provided on the inner wall of the insertion hole 301. By passing the sampling cup... When the sampling cup 6 is placed inside the socket 301, the bottom of the sampling cup 6 will directly contact the contact plate 14. The weight of the sampling cup 6 will put pressure on the contact plate 14. At this time, the limiting post 13 will slide inside the disc 12, causing the contact plate 14 to descend vertically and squeeze the first spring 15. Then the contact plate 14 will squeeze the clamping rod 11, causing the clamping rod 11 to swing. Then the squeezing block 16 will completely fit with the sampling cup 6, fixing the sampling cup 6. It can also be used to fit sampling cups 6 of different sizes.
[0028] Furthermore, in this embodiment, the second ring 4 has an internal receiving groove 17. Symmetrically fixed second springs 18 are fixedly connected to the inner wall of the receiving groove 17. An extrusion plate 19 is fixedly connected to the side of the two sets of second springs 18 that are close to each other. A silicone pad is provided on the inner wall of the extrusion plate 19. A TIP head 20 is slidably connected inside the extrusion plate 19. By inserting the TIP head 20 between the extrusion plates 19, the TIP head 20 applies a pushing force to the extrusion plate 19, causing the second springs 18 to contract. When the TIP head 20 is fully inserted into the receiving groove 17, the energy stored in the extension and retraction of the second springs 18 pushes the extrusion plates 19, causing the extrusion plates 19 to fit together and clamp TIP heads 20 of different sizes.
[0029] Furthermore, in this embodiment, a through hole is provided inside the third ring 5, and a reaction cup 21 is slidably connected inside the through hole. A mechanical gripper 22 is provided at the bottom of the monitor 1 and outside the stepper motor. A liquid level detector is provided at one end of the mechanical gripper 22, and a pipette is fixedly connected to the middle of the mechanical gripper 22. When sampling, the mechanical gripper 22 is controlled to move, making it easy to pull out the TIP head 20 inside the receiving tank 17. The design of the pipette can complete the liquid aspiration work. If the sample liquid level is too high, it may cause the calculation of parameters such as concentration and activity to be inaccurate; if the liquid level is too high, it may overflow and contaminate the equipment or dilute the reagent. The liquid level detector on the mechanical gripper 22 can accurately control the sample volume, ensure the standardization of analysis conditions, and avoid over-absorption or under-absorption.
[0030] Furthermore, in this embodiment, a track 23 is fixedly connected to the inner wall of the monitor 1, a moving block 24 is slidably connected to the outside of the track 23, a mounting block 25 is fixedly connected to the top of the moving block 24, semi-arc plates 26 are symmetrically fixedly connected to both ends of the top of the mounting block 25, a semi-worm gear 27 is fixedly connected between the semi-arc plates 26, a push plate 28 is slidably connected inside the semi-arc plates 26, a collar is fixedly connected to the top of the inner side of the push plate 28, a worm 29 is rotatably connected inside the collar, the worm 29 is adapted to the semi-worm gear 27, and an industrial camera is fixedly connected to the top of the push plate 28. A weighing module is provided at one end of the top of the connecting plate 2. An industrial camera is used to read the image after the sample reacts with the color developer. The pH value of the sample is determined by reading the color of the image. By rotating the worm 29, it meshes with the half worm wheel 27. The worm 29 moves along the half worm wheel 27, generating a moving force on the push plate 28 through the collar. Under the limiting action of the semi-arc plate 26, the push plate 28 completes the angle adjustment. The moving block 24 is controlled to slide outside the track 23, which can complete the lateral adjustment and facilitate data collection. The weighing module can perform sample buffering and weight reading.
[0031] In this embodiment, the specific implementation scenario is as follows: Semen is placed inside the sampling cup 6, which is then inserted into the socket 301. Simultaneously, a stepper motor is driven to rotate the connecting plate 2, causing the first ring 3, the second ring 4, and the third ring 5 to rotate synchronously. This causes the semen inside the sampling cup 6 to agitate, achieving a centrifugal mixing effect. Furthermore, when the sampling cup 6 is inserted into the socket 301, its bottom directly contacts the contact plate 14, where the weight of the sampling cup 6 exerts pressure on the contact plate 14. At this time, the limiting post 13 will slide inside the disc 12, causing the contact disc 14 to descend vertically and compress the first spring 15. Then, the contact disc 14 will compress the clamping rod 11, causing the clamping rod 11 to swing. Then, the extrusion block 16 will completely fit with the sampling cup 6, fixing the sampling cup 6. It is also compatible with sampling cups 6 of different sizes. By inserting the TIP head 20 between the extrusion plates 19, the TIP head 20 will apply a pushing force to the extrusion plates 19, causing the second spring 18 to retract. When the TIP head 20 is fully inserted into the receiving groove 17... After the second spring 18 extends and stores energy, it pushes the extrusion plates 19. The extrusion plates 19 fit together to clamp the TIP heads 20 of different sizes. By controlling the movement of the mechanical grippers 22, the TIP heads 20 can be easily pulled out from inside the receiving groove 17. The pipette design allows for liquid aspiration. The liquid level detector on the mechanical grippers 22 can precisely control the sample volume to ensure accurate analysis. If the sample liquid level is too high, it may cause errors in the calculation of parameters such as concentration and activity; if the liquid level is too high, it may overflow and contaminate the equipment or dilute the reagents. Standardized components prevent over- or under-absorption. An industrial camera is used to read images of the sample after reaction with the colorimetric reagent. The pH value of the sample is determined by reading the image color. By rotating the worm 29, it meshes with the semi-worm wheel 27. The worm 29 moves along the semi-worm wheel 27, generating a kinetic force on the push plate 28 through the collar. Under the limiting action of the semi-arc plate 26, the push plate 28 completes angle adjustment. The control of the moving block 24 to slide outside the track 23 can complete lateral adjustment, facilitating data collection. The weighing module can perform sample buffering and weight reading.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
