Description

Technical Field

[0001] This utility model relates to the field of cell staining technology, and in particular to a liquid transfer device for a cell slide staining machine. Background Technology

[0002] Cell preparation is a technique that processes cell samples so that their morphology, structure, and other characteristics can be clearly observed under a microscope.

[0003] The liquid transfer device is responsible for accurately transferring the collected cell sample suspension onto a glass slide or other slide carrier. By precisely controlling the amount of liquid and the transfer speed, it ensures that the cells are evenly distributed on the carrier, laying the foundation for subsequent fixation, staining and other steps.

[0004] Cell slide staining machines on the market extract liquid from a storage container and pressurize it into a transfer pipeline. The volume and speed of liquid transfer are precisely controlled by adjusting valve opening and closing and the speed of the drive mechanism. Finally, a nozzle or pipette tip evenly drips the liquid onto the designated location on the cell slide. However, in situations requiring precise transfer of minute amounts of liquid, such as the addition of certain special staining agents or fluorescent markers, liquid transfer devices struggle to achieve accuracy. This can lead to inaccurate dosages of critical reagents, affecting the accuracy and reproducibility of experimental results. Current technology involves periodically cleaning the various components of the liquid transfer device to prevent blockages and contamination, as well as to prevent liquid leakage and inaccurate flow rates. However, when dispensing liquid onto slides or other containers, the landing point cannot be precisely controlled. If the landing point deviates significantly, the cell sample may not be completely covered by the liquid, or the liquid may exceed the sample area, resulting in reagent waste and affecting the quality and consistency of the slide. Utility Model Content

[0005] To overcome the above shortcomings, this invention provides a liquid transfer device for a cell slide staining machine, which aims to improve the problem in the prior art where the inability to precisely control the landing point leads to the inability of cell samples to be completely covered in liquid.

[0012] Both motor one and motor two have a fixing block one fixedly connected to their bottom walls. The fixing block one is fixedly connected to the front and rear ends of the right side of the inner wall of the machine body.

[0013] As a further description of the above technical solution:

[0014] A controller is installed on the inner right side of the body, and multiple buttons are equidistantly installed on the front side of the outer wall of the controller.

[0015] As a further description of the above technical solution:

Motor two drives the rotating shaft one and the helical gear one to rotate, which in turn drives the helical gear two and the threaded rod two. The threaded rod two drives the threaded block two to rotate. The threaded block two, through its connection with the threaded block one, can move left and right, and its position can also be adjusted in the front and back directions by the rotation of the threaded rod two.

[0023] 2. In this utility model, the test tube is placed on the placement plate at the bottom of the sliding rack. When the pressure of the test tube decreases, the sliding rack drives the spur gear to rotate, and the spring is stretched accordingly. The movement of the spur gear causes the left and right sliding racks on the fixed plate to move towards each other along the sliding column. The sliding column ensures that the sliding racks can only move in a straight line. The sliding racks have clamping blocks. When they move towards each other, the clamping blocks clamp the item from both sides, thereby achieving all-round fixation of the item. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 3This utility model provides an embodiment of a liquid transfer device for a cell slide staining machine, comprising a body 1 and a belt 5. A motor 3 is located at the front end of the upper right side of the inner wall of the body 1.

The threaded rods 6 are used to drive the threaded blocks 7 to move. A motor 8 is set at the rear end of the upper right side of the inner wall of the machine body 1. The output end of the motor 8 is fixedly connected to a rotating shaft 9. The motor 8 drives the rotating shaft 9 to rotate. A helical gear 10 is slidably connected to the middle of the outer wall of the rotating shaft 9. The rotating shaft 9 drives the helical gear 10 to rotate. A helical gear 11 is meshed with the top wall of the helical gear 10. The helical gear 10 drives the upper... The helical gear 11 rotates on one side. A threaded rod 12 is fixedly connected to the front side of the outer wall of the helical gear 11. The helical gear 11 drives the threaded rod 12 to rotate. The threaded rod 12 is rotatably connected to the upper part of the inner wall of the threaded block 7.

The threaded block 13 is slidably connected to the left side of the outer wall of the threaded block 7. A distributor 14 is fixedly connected to the left side of the outer wall of the threaded block 13. The distributor 14 is used to accurately distribute liquid to specific locations or containers. Multiple placement racks 15 are fixedly connected at equal intervals on the outer and inner sides of the body 1. The placement rack 15 is equipped with a fixing mechanism 2 inside, which is used to fix the test tubes. A baffle 16 is fixedly connected to the inner left end of the body 1. The baffle 16 is used to protect the placement racks 15 inside the body 1. Fixing blocks 17 are fixedly connected to the bottom walls of motor 1 3 and motor 2 8. Fixing blocks 17 are fixedly connected to the front and rear ends of the right side of the inner wall of the body 1. The function of fixing blocks 17 is to securely install motor 1 3 and motor 2 8 on the body 1.

[0033] Specifically, starting motor 3 drives the front pulley 4 to rotate. Since the two pulleys 4 are connected by a belt 5, the rear pulley 4 also rotates. The pulley 4 drives the threaded rod 6 to rotate, and the threaded block 7 moves on the threaded rod 6. Starting motor 8 drives the shaft 9 to rotate, which in turn drives the helical gear 10 to rotate and slide. The helical gear 10 drives the upper helical gear 11 to rotate, which in turn drives the threaded rod 12 to rotate. The threaded rod 12 drives the threaded block 13 to rotate. Since the threaded block 13 is slidably connected to the left side of the outer wall of the threaded block 7, the threaded block 13 moves left and right under the drive of the threaded block 7, and can also move through the threaded rod 6. The rotation of the threaded rod 12 enables position adjustment in the front and back directions. A dispenser 14 is fixedly connected to the left side of the outer wall of the threaded block 13. The dispenser 14 is used to accurately distribute liquid to a specific location or container. By controlling the rotation direction, speed and time of the motor 1 and motor 2, the position and movement path of the dispenser 14 can be accurately adjusted to adapt to different cell preparation and staining needs. Multiple placement racks 15 are fixedly connected at equal intervals on the outer and inner sides of the machine body 1. The placement rack 15 is equipped with a fixing mechanism 2 inside.

[0034] Reference Figure 1 , Figure 4 and Figure 5The fixing mechanism 2 includes a fixing plate 201 fixedly connected to the rear inner wall of the placement rack 15. A rotating shaft 202 is fixedly connected to the upper middle part of the front side of the outer wall of the fixing plate 201. A spur gear 203 is fixedly connected to the front end of the rotating shaft 202, and the spur gear 203 rotates on the rotating shaft 202. A sliding rack 204 is meshed with the outer wall of the spur gear 203, and the sliding rack 204 drives the spur gear 203 to rotate. A placement plate 205 is fixedly connected to the bottom wall of the sliding rack 204. The placement plate 205 is used to place test tubes. Springs 206 are fixedly connected to the left and right ends of the rear side of the top wall of the placement plate 205. The springs 206 are used for rebound. A fixing block 207 is fixedly connected to the top of the springs 206. The fixed plate 201 is fixedly connected to the lower middle part of the front side of the top wall. The left and right ends of the front side of the outer wall of the fixed plate 201 are fixedly connected to the sliding column 208. The outer wall of the sliding column 208 is slidably connected to the sliding rack 209. The sliding rack 209 meshes with the spur gear 203. The outer walls of the two sliding racks 209 are fixedly connected to the side away from each other. The clamping block 210 is used to clamp the items placed in the placement rack 15 from both sides to achieve all-round fixation of the items. The top wall of the placement plate 205 is equipped with a buffer pad 22. The buffer pad 22 plays a role in buffering and shock absorption, reducing the impact on the sample caused by the vibration during the placement action or the operation of the device, making the sample placed on it more stable and less likely to slide or shake.

[0035] Specifically, the test tube is placed on the placement plate 205 at the bottom of the sliding rack 204. When the placement plate 205 is lowered by the pressure of the test tube, the sliding rack 204 drives the spur gear 203 to rotate, and the spring 206 is stretched. At this time, the spur gear 203 drives the left and right sliding racks 209 on the fixed plate 201 to move towards each other on the sliding column 208. The sliding column 208 plays a guiding role, ensuring that the sliding racks 209 can only move in a straight line along the direction of the sliding column 208. Both sliding racks 209 have clamping blocks 210. Therefore, when the sliding racks 209 move towards each other, the clamping blocks 210 will clamp the items placed in the placement rack 15 from both sides, realizing the all-round fixation of the items. The buffer pad 22 plays a role in buffering and shock absorption, reducing the impact on the sample caused by the vibration during the placement action or the operation of the device, making the sample placed on it more stable and less likely to slide or shake.

[0036] Reference Figure 1 and Figure 2A controller 18 is installed on the inner right side of the body 1. The controller 18 is used to control various operating parameters and functions of the device to ensure that the liquid transfer process is accurate and stable. Multiple buttons 19 are installed at equal intervals on the front side of the outer wall of the controller 18. The buttons 19 are used to control the controller 18. A placement slot 20 is opened on the rear side of the top wall of the controller 18. The placement slot 20 is used to place the storage bottle 21 and provides a fixed storage position for the storage bottle 21. The storage bottle 21 is installed inside the placement slot 20. The storage bottle 21 is used to store various liquids, such as dyeing solution, fixing solution and washing solution. Support feet 23 are fixedly connected to the four corners of the bottom wall of the body 1. The support feet 23 are used to keep the body 1 in a stable posture and avoid the body 1 tilting or shaking due to uneven ground or other factors. Anti-slip pads 24 are fixedly connected to the bottom wall of the support feet 23. The anti-slip pads 24 are used to prevent the body 1 from sliding during placement, which further improves the stability and safety of the device and ensures that the device can maintain a fixed position during operation, avoiding damage or affecting the work due to accidental sliding.

[0038] Working principle: Start motor 3, which drives the front pulley 4 to rotate. Since the two pulleys 4 are connected by belt 5, the rear pulley 4 will also rotate. The pulley 4 drives the threaded rod 6 to rotate, and the threaded block 7 moves on the threaded rod 6. Start motor 8, which drives the shaft 9 to rotate. The shaft 9 drives the helical gear 10 to rotate and slide. The helical gear 10 drives the upper helical gear 11 to rotate. The helical gear 11 drives the threaded rod 12 to rotate. The threaded rod 12 drives the threaded block 13 to rotate. Since the threaded block 13 is slidably connected to the left side of the outer wall of the threaded block 7, the threaded block 13 will move left and right under the drive of the threaded block 7, and can also adjust its position in the front and back directions through the rotation of the threaded rod 12. The distributor 14 is fixedly connected to the left side of the outer wall of the threaded block 13. By controlling the rotation direction, speed and time of motor 3 and motor 8, the position and movement path of the distributor 14 can be accurately adjusted to adapt to different cell preparation and staining needs.

[0039] When the test tube is placed on the placement plate 205 at the bottom of the sliding rack 204, the placement plate 205 drops due to the pressure of the test tube. The sliding rack 204 drives the spur gear 203 to rotate, and the spring 206 is stretched. At this time, the spur gear 203 drives the left and right sliding racks 209 on the fixed plate 201 to move towards each other on the sliding column 208. The sliding column 208 acts as a guide to ensure that the sliding racks 209 can only move in a straight line along the direction of the sliding column 208. Both sliding racks 209 have clamping blocks 210. Therefore, when the sliding racks 209 move towards each other, the clamping blocks 210 will clamp the items placed in the placement rack 15 from both sides, thereby achieving all-round fixation of the items.
