[0002] At present, in clinical medicine, the presence of lesions in the human body is often judged by observing cell slides of various tissues of the human body. With the rapid development of science and technology and social economy, it has greatly promoted the development of pathological analysis technology, making the second-generation liquid-based cell slide making technology represented by the sedimentation liquid-based cell slide making technology more and more widely used in the preparation of cytopathology specimens. In the prior art, the production process of liquid-based cell slides includes steps such as sampling, centrifugation, smearing, and staining.

[0003] In the sampling stage, the sample is mostly taken by a manipulator. After sampling, the sample position is transferred and the sample is stained at the same time. Due to the action of liquid tension during sampling, after sampling, there will be a sample residue similar to a water droplet on the lower surface of the suction tube. When the manipulator moves, the sample will be thrown off due to the action of inertia. For this reason, we propose a slide making and staining machine capable of preventing liquid taking from falling off. Content of the Utility Model

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1

[0026] Please refer to Figures 1-6 , the present utility model provides a technical solution: a slide staining machine that can prevent the liquid from falling off, including a body 1, and the outer surface of the body 1 is movably connected with a machine head 11,

[0027] a compensation component 2, the compensation component 2 is located at the bottom of the machine head 11, compensates the sucked liquid after sucking the liquid, and also sucks the excess liquid into the suction tube 4 to prevent the liquid from dripping due to inertia when the machine head 11 moves;

[0028] a trigger component 3, the trigger component 3 is located on one side of the compensation component 2, and triggers the compensation component 2 through the position when the machine head 11 sucks the liquid.

[0029] The compensation component 2 includes a fixed plate 20, the fixed plate 20 is fixedly connected to the outer surface of the lower end of the machine head 11, a compensation groove 28 is opened on the outer surface of the lower end of the fixed plate 20, a suction rod 27 is slidably connected inside the compensation groove 28, a compensation plate 21 is fixedly connected to the outer surface of the suction rod 27, an iron sheet 23 is fixedly connected to the outer surface of the rear end of the compensation plate 21, and an electromagnet 22 is fixedly connected to the corresponding position of the rear end of the fixed plate 20 and the iron sheet 23;

[0030] When the head 11 moves upward after sucking a sufficient amount of liquid inside the sample, due to the surface tension of the liquid, water droplet-shaped liquid will adhere to the bottom of the suction tube 4. When the head 11 rises to a certain position, the trigger assembly 3 triggers the electromagnet 22 to cut off the power. The compensation plate 21 slides downward along the compensation groove 28 through the suction rod 27. At this time, the space inside the compensation groove 28 increases to generate suction, sucking the liquid adhering to the bottom of the suction tube 4 into the suction tube 4 as well, avoiding the liquid droplets being thrown off due to inertia when the head 11 moves horizontally.

[0031] A telescopic rod 24 is fixedly connected to the outer surface of the upper end of the compensation plate 21. A telescopic groove 25 is provided at the corresponding position on the outer surface of the lower end of the fixed plate 20. The telescopic rod 24 is located inside the telescopic groove 25. A spring 26 is fixedly connected between the telescopic groove 25 and the telescopic rod 24. After the electromagnet 22 cuts off the power, the spring 26 pushes the telescopic rod 24 and the compensation plate 21 downward, and at the same time, the maximum downward movement distance of the compensation plate 21 is restricted by the telescopic rod 24 and the telescopic groove 25.

[0032] The lower outer surface of the suction rod 27 is sleeved with a suction tube 4. A vertical tube 40 is fixedly connected to the position of the suction tube 4 close to the lower end, sucking the water droplet-shaped liquid into the vertical tube 40, increasing the stability of the liquid and avoiding it being thrown off.

[0033] The compensation assembly 2 includes a trigger rod 32. The trigger rod 32 is connected to the outer surface of the upper end of the machine body 1 and corresponds to the head 11. A trigger groove 34 is provided at one end of the trigger rod 32 close to the head 11. A resistance sheet 35 is provided inside the trigger groove 34. A trigger plate 33 is in contact with the surface of the resistance sheet 35. One end of the trigger plate 33 away from the trigger rod 32 is fixedly connected to the fixed plate 20. When the head 11 moves downward, the trigger plate 33 contacts different positions of the resistance sheet 35. The trigger plate 33 is electrically connected to the resistance sheet 35 and the electromagnet 22. The resistance of the resistance sheet 35 decreases from top to bottom. When the head 11 drives the trigger plate 33 close to the sample, the electromagnet 22 is in the energized state. At this time, the compensation plate 21 is in contact with the fixed plate 20. When the head 11 and the trigger plate 33 move upward, the trigger plate 33 slides upward along the resistance sheet 35, and the suction force of the electromagnet 22 on the iron sheet 23 gradually decreases.

[0034] Embodiment 2

[0035] The resistance sheet 35 is designed in an L-shaped structure. A threaded groove 36 is provided at the upper end of the resistance sheet 35. The upper end of the trigger rod 32 is rotatably connected to a threaded rod 37 through a rotating shaft. The threaded rod 37 is threadedly connected to the threaded groove 36. For samples of different batches with different heights, the position of the resistance sheet 35 can be adjusted to change the triggering time of the compensation assembly 2, ensuring that the liquid at the bottom of the suction tube 4 is inside the vertical tube 40 when the head 11 moves horizontally, avoiding the liquid being thrown off due to inertia.

[0036] A chute 30 is provided on the outer surface of the upper end of the body 1. A slider 31 is slidably connected inside the chute 30. The slider 31 is fixedly connected to the lower end of the trigger rod 32. The cooperation between the slider 31 and the chute 30 enables the trigger assembly 3 to move horizontally synchronously with the nose 11.
