[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0047] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0048] Before and after cell staining, the slides need to be rinsed with running water to prevent excessive acidic dissociation solution added previously. The staining solution is alkaline and reacts with the acidic solution, affecting the normal staining of the slides.

[0049] In the related art, the cell staining rack does not have the function of tilting the slide after fixing the slide, so it is inconvenient to rinse the slide with running water, and cannot adapt to the fixation of slides of different sizes, and has poor practicality.

[0050] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides a cell staining device rack. When rinsing is required, the device only needs to be moved to the side of the sink after the dissociation is completed. The operator controls the push of the electric push rod 22. When the electric push rod 22 is extended, one end of the pick box 21 is lifted, so that the pick box 21 is rotated and lifted along the end hinged to the base 11, and the pick box 21 is tilted. At this time, the operator controls the opening of the solenoid valve 24. After the solenoid valve 24 is opened, the dissociation liquid flows out of the pick box 21 through the outlet pipe 23. The operator rinses the glass slide fixed in the pick box 21 with a uniform flow of water. The tilted pick box 21 is more convenient for rinsing the glass slide.

[0051] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0052] Combination Figure 1-Figure 5The embodiment of the present application provides a cell staining device frame, including a frame component 1, the frame component 1 includes: a vertical plate 12 is arranged on the top of the base 11, and a rinsing component 2 is arranged on the base 11 and the vertical plate 12, and the rinsing component 2 includes: a paddle box 21 is connected to the top of the base 11 by a hinge, an electric push rod 22 is arranged between the base 11 and the paddle box 21, and the two ends of the electric push rod 22 are respectively connected to the base 11 and the paddle box 21 by hinges, a water outlet pipe 23 is arranged on the outer side wall of the paddle box 21, a solenoid valve 24 is arranged on the water outlet pipe 23, and a fixing component 3 is arranged on the paddle box 21.

[0053] When in use, the slide to be stained is placed in the pick box 21, the slide is fixed by the fixing component 3, and the dissociation solution is poured into the pick box 21 to facilitate the separation of cells in the slide for observation. After the dissociation is completed, the device is moved to the side of the sink, and the residual dissociation solution on the slide is conveniently rinsed with running water by the rinsing component 2: the operator controls the push of the electric push rod 22, and when the electric push rod 22 is extended, one end of the pick box 21 is lifted, so that the pick box 21 is rotated and lifted along the end hinged to the base 11, and the pick box 21 is lifted. Tilt, at this time, the operator controls the opening of the electromagnetic valve 24. After the electromagnetic valve 24 is opened, the dissociation liquid flows out of the pick box 21 through the outlet pipe 23 until it flows into the pool. The operator does not need to clean it. After the dissociation liquid flows out, the operator rinses the fixed slide in the pick box 21 with uniform running water. Since the pick box 21 has driven the slide to tilt, the tilted slide is easier for the operator to rinse with running water. At the same time, when rinsing with running water, the dissociation liquid remaining on the inner wall of the pick box 21 is also cleaned to avoid the reaction between the dissociation liquid and the dye. After rinsing, the operator controls the electric push rod 1 22 to retract, and the electric push rod 1 22 drives the pick box 21 to return. At this time, the electromagnetic valve 24 is controlled to close, and the dye is poured into the pick box 21. The dye dyes the cells in the slide. After the dyeing is completed, the dye is rinsed again with the rinsing component 2 to avoid excessive dye residues that affect the operator's subsequent observation of the cells.

[0054] Specifically, the electric push rod 22 is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. It can be used as an execution machine in various simple or complex process flows to achieve remote control, centralized control or automatic control. The solenoid valve 24 is an industrial device controlled by electromagnetics. It is an automated basic component used to control fluids. It belongs to an actuator and is not limited to hydraulics or pneumatics. When the power is turned on, the electromagnetic force opens the pilot hole, the pressure in the upper chamber drops rapidly, and a pressure difference with a low top and a high bottom is formed around the closing part. The fluid pressure pushes the closing part to move upward and the valve opens; when the power is turned off, the spring force closes the pilot hole, and the inlet pressure quickly passes through the bypass hole to form a pressure difference with a low bottom and a high top around the closing valve part. The fluid pressure pushes the closing part to move downward and close the valve. The above structural principles are not drawn in the attached drawings.

[0055] In some embodiments, the fixing assembly 3 includes: a motor 31 is arranged on the outer wall of the paddle box 21, one end of the bidirectional screw rod 32 is fixedly connected to the output shaft of the motor 31, and the other end is rotatably connected to the rack of the outer wall of the paddle box 21, a threaded block 33 is sleeved on the bidirectional screw rod 32 and threadedly connected to the bidirectional screw rod 32, a through groove 1 341 is arranged in the paddle box 21, a cross telescopic frame 34 is arranged on the outer wall of the threaded block 33, and is located in the through groove 1 341, a rotating shaft 35 is arranged on one side of the cross telescopic frame 34, a through groove 2 361 is arranged on the inner wall of the paddle box 21, a splint 36 is arranged on the side of the rotating shaft 35 away from the cross telescopic frame 34, and one end of the splint 36 extends out of the through groove 2 361, an electric push rod 2 37 is arranged at the top of the paddle box 21, and a fixing plate 38 is fixedly connected to the output shaft of the electric push rod 2 37.

[0056] The thickness and length of glass slides of different batches are different. The fixing assembly 3 fixes the glass slides of different thicknesses and lengths between the batches: the glass slides of the same batch with the same thickness and length are vertically and dispersedly placed between the clamping plates 36 in the pick box 21. The operator controls the motor 31 to start, and the motor 31 drives the bidirectional screw rod 32 to rotate. When the bidirectional screw rod 32 rotates, the thread blocks 33 threadedly connected to the bidirectional screw rod 32 move toward or away from each other according to the rotation direction of the bidirectional screw rod 32. After the rotation direction of the bidirectional screw rod 32 is controlled so that the thread blocks 33 are separated from each other, the cross extension hinged on the thread block 33 is The intersection parts of the retractable frames 34 are close to each other, and the rotating shaft 35 drives the clamping plates 36 to approach each other. The clamping plates 36 fix and clamp the glass slide placed in the middle. Since the gap between the clamping plates 36 can be adjusted by moving the threaded block 33, when different batches of glass slides are placed in the pick box 21, it can be adjusted to clamp glass slides of different thicknesses. The operator then controls the electric push rod 2 37 to start, and the electric push rod 2 37 drives the fixed plate 38 to approach the clamping plate 36 and abut against the glass slide clamped on the clamping plate 36. The moving distance of the fixed plate 38 is adjusted according to the length of the glass slide, so that the fixing component 3 is more practical.

[0057] Specifically, the bidirectional screw 32 is a screw with two sections of threads with different rotation directions, that is, one section is a right-hand thread and the other section is a left-hand thread. The right-hand and left-hand nuts screwed thereon are connected to the moving parts respectively. When the screw rotates, the two moving parts quickly approach or separate with the nuts, thereby generating the required mechanical function. The through slot 1 341 provided on the paddle box 21 for the movement of the cross telescopic frame 34 is a rectangular parallelepiped structure, and its internal space is sufficient for the cross telescopic frame 34 to be telescopic. The through slot 2 361 provided on the paddle box 21 for the movement of the splint 36 is rectangular, and the splint 36 extends into the paddle box 21 through the through slot 2 361. The cross telescopic frame 34 includes a plurality of telescopic parts composed of two crossed metal sheets, which are connected in sequence and can be telescopic. The rotating shaft 35 rotates when the angle of the intersection of the cross telescopic frame 34 changes, and the rotating shaft 35 is rotatably connected to the splint 36. When the rotating shaft 35 rotates, the splint 36 does not rotate. When the bidirectional screw rod 32 rotates, the threaded block 33 threadedly connected thereto is hinged with the cross telescopic frame 34, and one end of the cross telescopic frame 34 extends into the through slot on one side of the paddle box 21, thereby restricting the movement of the threaded block 33, so that the threaded block 33 cannot rotate with the rotation of the bidirectional screw rod 32.

[0058] In some embodiments, at least two electric push rods 1 22 are provided to increase the stability when the electric push rod 1 22 pushes the paddle box 21 to rotate and tilt.

[0059] In some embodiments, one side of the fixing plate 38 has a groove 381, and the groove 381 is rectangular. When the fixing plate 38 is close to the vertically placed slide, the slide is restricted, the contact area with the fixing plate 38 is increased, and the slide is prevented from shaking.

[0060] In some embodiments, a slider 25 is provided on the outer wall of the paddle box 21, and a slide groove 26 is provided on the inner wall of the vertical plate 12. One end of the slider 25 slides on the slide groove 26. When the paddle box 21 is tilted, the paddle box 21 drives the slider 25 to slide in the slide groove 26, thereby increasing the stability of the paddle box 21 when it is tilted.

[0061] In some embodiments, a handle 13 is provided on the vertical plate 12, and the handle 13 facilitates the operator to lift the device to the side of the sink for rinsing.

[0062] In some embodiments, a guide rail shield 4 is provided in the second through slot 361. The guide rail shield 4 is in a straight line shape, the same shape as the second through slot 361, and is a part with telescopic properties, usually made of flexible materials such as rubber, silicone, etc. The guide rail shield 4 has a certain telescopic property and can be freely extended with the movement of the force-bearing object. The guide rail shield 4 is sleeved on the outside of the clamping plate 36, and is extended and retracted with the movement of the clamping plate 36, protecting the second through slot 361, preventing moisture from entering the second through slot 361 during cell staining, and causing rust damage to the parts of the fixed component 3.

[0063] In some embodiments, the slide groove 26 is arc-shaped, and the shape of the slide groove 26 faces the rotation and tilting movement trajectory of the paddle box 21 to prevent the slider 25 from getting stuck in the slide groove 26 and affecting the normal tilting of the paddle box 21 .
