[0030] Example 1: Please refer to Figures 1 to 6 :
[0031] This invention discloses an automatic sperm smear staining device, comprising: a slide holder 1, a smear holder 2, a solution container 3, and a worktable 4. The slide holder 1 is fixedly disposed outside a central rotating frame 101, which is circumferentially rotatable outside an inner lifting frame 102. The inner lifting frame 102 is screwed to an electric lifting screw 103, and the inner lifting frame 102 and the central lifting rod 104 are vertically connected and slidably connected. A drive motor 105 is fixedly installed on the top of the inner lifting frame 102. The slide holder 1 is located above the solution container 3. The top of the solution container 3 is provided with a slidable and sealable upper sealing cover 301, which is fixedly connected to the telescopic rod of a second telescopic cylinder 302. The second telescopic cylinder 302 is fixedly connected to the worktable 4, and the solution container 3 is disposed on the top of the worktable 4. A support platform 402 is fixedly disposed on the front side of the smear holder 2 on the worktable 4. The worktable 4 is provided with an upper sliding slot 4 arranged in a ring around the central lifting rod 104. 01. The upper sliding slot 401 and the solution box 3 are slidably connected. The upper sliding slot 401 can also be internally fitted with an absorbent sponge to absorb excess solution from the slide holder 1. The top of the worktable 4 is equipped with a smear holder 2. Sliding side clamps 201 are symmetrically arranged on both sides of the smear holder 2. A central connecting tension spring 202 is fixed between the side clamps 201 on both sides of the smear holder 2. The rear side of the smear holder 2 is rotatably connected to the first end of the rear support screw 203. The rear section of the rear support screw 203 is screwed to the rear support screw tube 204. The tail end of the rear support screw tube 204 is circumferentially connected to the lower connecting frame 205. The lower connecting frame 205 is rotatably mounted on the top of the lower moving slide 206. The lower moving slide 206 is fixedly connected to the telescopic rod of the first telescopic cylinder 207. The smear holder 2 adjusts its support angle through the cooperation of the rear support screw 203 and the rear support screw tube 204 to achieve precise control of the slide pulling angle.
[0032] In this embodiment, the upper motor and the middle lifting rod 104 of the electric lifting screw 103 are fixed, and the lower end of the electric lifting screw 103 is rotatably connected to the worktable 4. The main shaft of the drive motor 105 meshes with the external gear block of the middle rotating frame 101 through gears. The lower end of the middle lifting rod 104 is fixedly connected to the worktable 4. The thread of the electric lifting screw 103 guides the inner lifting frame 102, the middle rotating frame 101, and the slide holder 1 to move vertically downward. The slide holder 1 enters the solution box 3 for slide immersion. The slide holder 1 rotates and rises with the middle rotating frame 101 to sequentially perform the immersion and staining process on the multiple solution boxes 3 below, thereby improving detection efficiency, ensuring the consistency of staining results, and reducing manual operation.
[0033] In this embodiment, the lower connecting frame 205 is horizontally slidably disposed on the top of the workbench 4, the first telescopic cylinder 207 is fixed on the top of the workbench 4, the middle part of the smear holder 2 is rotatably connected to the rotating shaft of the workbench 4, and the first telescopic cylinder 207 pushes the lower connecting frame 205 and the smear holder 2 to move horizontally, so that the glass slide of the smear holder 2 can perform smearing operation on the semen on the glass slide on the top of the support platform 402, eliminating the manual smearing process and avoiding the inconsistency and error problems caused by manual smearing.
[0034] In this embodiment, the second telescopic cylinder 302 is fixedly installed on the top of the workbench 4. When the second telescopic cylinder 302 extends, it pushes the upper sealing cover 301 to move away from the solution box 3. At this time, the top of the solution box 3 is in an open state. When the second telescopic cylinder 302 shortens, it drives the upper sealing cover 301 to move and cover the top of the solution box 3. The solution box 3 is in a sealed state at this time. After the solution box 3 is sealed, the evaporation of the solution inside the solution box 3 is reduced, and the harmful gases generated by the evaporation of the liquid inside the solution box 3 in the experimental environment are reduced, making the experimental environment safer.
[0035] In Example 2, based on Example 1, the workbench 4 is further equipped with a turbidity measurement module. By comparing the turbidity display image of the standard sample, the concentration of sperm used for smear is ensured to be within a suitable concentration range. The turbidity measurement module includes a light source, a cuvette, and a control image or sample, and is used to measure and adjust the sperm concentration to ensure that the sperm concentration is at a uniform level.
[0036] The working principle of this embodiment is as follows: A glass slide is placed on the top of the support platform 402, and a glass slide is placed at an angle on the top of the smear holder 2. The connecting spring 202 pulls the side clamping block 201 to clamp the middle glass slide. The lower part of the glass slide on the top of the smear holder 2 is at the top of the glass slide on the top of the support platform 402. The first telescopic cylinder 207 pushes the connecting frame 205 and the smear holder 2 to move horizontally. The glass slide on the smear holder 2 performs a smearing operation on the semen on the glass slide on the top of the support platform 402, eliminating the need for manual smearing, reducing the labor intensity of personnel, and eliminating the inconsistency and error problems caused by manual smearing. The rear support screw tube 204 rotates circumferentially, and the thread of the rear support screw tube 204 guides the rear support screw 203 to move axially. The rear support screw 203 and rear support tube 204 extend to support the slide holder 2 to rotate around the connecting shaft between the slide holder 2 and the lower moving slide 206 to adjust the angle. The support angle of the slide holder 2 is adjusted by the cooperation of the rear support screw 203 and rear support tube 204. The slide holder 2 is generally kept at a 40-degree tilt. At the same time, the extension and retraction of the first telescopic cylinder 207 controls the moving speed of the slide holder 2 and the glass slide, realizing precise control of parameters such as the slide speed and the slide pulling angle, ensuring the stability of the slide quality, effectively avoiding the problem of error in sperm morphology interpretation caused by operational errors in parameters such as the slide speed and the slide pulling angle between different workers and batches, and providing more reliable slide samples for sperm morphology analysis.
[0037] Slides after smearing are placed inside slide holder 1. Drive motor 105, through gear meshing, rotates the rotating frame 101 and slide holder 1 to above solution container 3, which remains open. The electric lifting screw 103 guides the inner lifting frame 102, the rotating frame 101, and slide holder 1 vertically downwards, allowing slide holder 1 to enter solution container 3 for slide immersion. As the rotating frame 101 rotates and rises, slide holder 1 sequentially immerses and stains multiple solution containers 3 below. The immersion time is precisely controlled via a PLC module, improving detection efficiency and ensuring staining accuracy. To ensure the consistency of color results and thus the accuracy of the test results, when the slide holder 1 is above the solution box 3, the extension rod of the second telescopic cylinder 302 extends, causing the upper sealing cover 301 to move away from the solution box 3, thereby opening the solution box 3. When the extension rod of the second telescopic cylinder 302 shortens, it causes the upper sealing cover 301 to move and cover the solution box 3, thereby closing and sealing the solution box 3. After the solution box 3 is closed and sealed, the evaporation of the solution inside the solution box 3 is reduced, and the harmful gases generated by the evaporation of the solution box 3 in the experimental environment are reduced, providing a safe environment for the experimental personnel and helping to protect the health of the experimental personnel.
