Description

Technical Field

[0001] The invention relates to the technical field of slide staining tools, in particular to a washing device for pathological special staining slides. Background Art

[0002] Pathology special staining slides are important tools for observing and analyzing tissue samples in pathology research and diagnosis. Special staining techniques can make certain structures or components that are difficult to identify under conventional staining appear in specific colors, thereby helping pathologists to more accurately identify and diagnose diseases. In the pathology laboratory, rinsing of slides is a key step, which usually occurs after the staining process. The purpose is to remove unbound stains on the slides to reduce background staining and improve the contrast and clarity of the samples.

[0003] Traditional slide washing methods mainly rely on manual operations, which is not only inefficient, but also prone to uneven washing due to human factors, affecting the staining effect. In addition, manual washing may also cause waste of dye solution and environmental pollution, while also increasing the labor intensity of operators and the risk of exposure to potentially harmful chemicals. Although some automatic slide staining devices have appeared and can wash multiple slides at the same time, there are still some inconveniences and inefficiencies. For example, when washing slides, the angles between the slides and the washing nozzles are mostly fixed, resulting in insufficient flexibility in the positioning and angle adjustment of the slides during the washing process, resulting in uneven washing and affecting the staining quality.

[0013] Specifically, the linkage mechanism includes a displacement plate and a guide bevel.

[0014] Furthermore, a plurality of extruded rubber blocks are equidistantly arranged on both sides of the inner side of the clamping and limiting groove.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. The present invention realizes precise adjustment of the angles of the support frame and the washing nozzle by arranging an angle adjustment component between the support frame and the washing component, which includes a first angle adjustment member and a second angle adjustment member. By adjusting the angle of the support frame, the contact angle of the glass slide relative to the washing liquid can be changed, thereby optimizing the flow path and coverage of the washing liquid on the glass slide, improving the washing efficiency and uniformity. At the same time, by adjusting the angle of the washing nozzle, the spray direction and impact force of the washing liquid can be accurately controlled, further enhancing the washing effect. In particular, when removing stubborn staining residues, the angle adjustment can provide a more targeted washing force. 2. The present invention further provides a linkage mechanism so that the first angle adjustment member and the second angle adjustment member can be adjusted synchronously. This synchronous adjustment mechanism ensures that when the angle of the slide is changed, the angle of the flushing nozzle can also be adjusted accordingly to maintain the best flushing effect. This linkage adjustment design not only improves the convenience of operation, but also enhances the accuracy and repeatability of the flushing process, thereby achieving efficient and uniform flushing of special pathological stained slides. 3. The present invention forms an efficient waste liquid recovery system by jointly setting up the water guide groove opened on the bottom plate along its length direction, the corresponding hollow holes on the vertical plate and the water collecting funnel. The design of the water guide groove is based on the concept of drainage in fluid mechanics. By placing one end of the water guide groove close to the horizontal plate and tilting the other end upward, the flushing liquid is guided to flow along the groove by gravity, thereby realizing effective collection and drainage of the flushing liquid, which not only reduces the splashing and overflow of the flushing liquid during the flushing process, but also avoids the pollution of the laboratory environment, and also reduces the risk of secondary contamination of the glass slide due to the residual flushing liquid. At the same time, a waste liquid collection box is provided, so that the waste liquid collected by the water collecting funnel can be collected centrally, realizing centralized treatment and recycling of the waste liquid, and reducing the environmental pollution and waste liquid treatment cost of the laboratory; 4. The present invention further provides a guide block, a hemispherical groove and a guide rod, so that the flushing nozzle can achieve complex multi-directional angle adjustment. Specifically, when the second angle adjustment member is working, the second slide rod moves along the length direction of the connecting plate, and after the second slide rod moves, it can drive the swing rod to swing inside it through the strip groove, and after the swing rod swings, it can drive the flushing nozzle to swing back and forth along the length direction of the connecting plate, and when the flushing nozzle swings, it can drive the guide rod to move in the hemispherical groove through the spherical body, and due to the curved inner wall shape of the hemispherical groove, when the guide rod moves on the inner wall of the hemispherical groove, the curved inner wall of the hemispherical groove will generate a rotational torque around the center of the sphere on the guide rod, thereby prompting the guide rod to push the spherical body to swing left and right in the spherical groove, so that the angle adjustment of the flushing nozzle is more flexible when washing the glass slide, and the adaptability and convenience of the equipment are greatly enhanced.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and drawings. The schematic implementation modes and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.

[0019] It should be noted that during the staining process of special pathological stained slides, specific stains need to be used to stain tissue samples in order to observe specific cells or tissue structures under a microscope. After staining, unbound stains will remain on the slides, and these residues will interfere with the observation results, so they need to be removed by rinsing. Effective rinsing can reduce background staining and improve the contrast and clarity of the sample. However, when rinsing slides in the prior art, the rinsing operation is often cumbersome and the rinsing efficiency is low. It is difficult to centrally recycle the rinsing liquid after rinsing, resulting in certain pollution to the environment. In view of this, this embodiment provides a rinsing device for special pathological stained slides, which realizes an automated and precisely controlled slide rinsing process, as described in the following embodiments.

[0020] Example Please refer to the attached Figures 1 to 6 The present embodiment provides a washing device for specially stained pathological slides, comprising a base, a placement rack for placing slides is provided on the upper part of the base, the placement rack is L-shaped, comprising a vertical plate 10 and a horizontal plate 11, a supporting assembly is arranged on the side of the vertical plate 10, the supporting assembly comprises a bottom plate 20 and a plurality of supporting racks, and the plurality of supporting racks are arranged equidistantly along the length direction of the bottom plate 20; like Figure 2 As shown, each of the support frames includes a support plate 210 and a side baffle 211. The length direction of the support plate 210 is arranged along the width direction of the bottom plate 20 and is perpendicular to the length direction of the bottom plate 20. The bottom of the support plate 210 is rotatably connected to the bottom plate 20 through a rotating shaft. The side baffles 211 are symmetrically arranged at both ends of the length direction of the support plate 210. A clamping limit groove 2110 is opened inside the two side baffles 211. like Figure 1 and Figure 3 As shown, a flushing assembly is also provided on the upper part of the supporting assembly, and the flushing assembly includes a connecting plate 30 connected to the vertical plate 10 at one end, and a plurality of flushing assemblies arranged along the length direction of the connecting plate 30 and corresponding to the supporting bracket are provided at the bottom of the connecting plate 30, each of the flushing assemblies includes a mounting plate 310 and a flushing nozzle 311, the length direction of the mounting plate 310 is parallel to the length direction of the connecting plate 30, and the mounting plate 310 is connected to the connecting plate 30 through connectors at both ends thereof, and the flushing nozzle 311 is ball-connected to the mounting plate 310 through a ball joint 312; like Figure 1 As shown, an angle adjustment component is also provided between the supporting component and the flushing component, and the angle adjustment component includes a first angle adjustment member located on the base plate 20 for adjusting the angle of the supporting frame, and a second angle adjustment member located at the bottom of the connecting plate 30 for adjusting the angle of the flushing nozzle 311. A linkage mechanism is also provided between the first angle adjustment member and the second angle adjustment member, and the first angle adjustment member and the second angle adjustment member are synchronously started by the linkage mechanism to adjust the angles of the supporting frame and the flushing nozzle 311 respectively.

[0021] The core of the washing device described in the above embodiment is an L-shaped placement rack, including a vertical plate 10 and a horizontal plate 11. A supporting assembly is arranged on the side of the vertical plate 10 for placing and fixing the glass slide. The supporting assembly consists of a bottom plate 20 and a plurality of supporting frames. The supporting frames are arranged equidistantly along the length direction of the bottom plate 20. Each supporting frame includes a supporting plate 210 and a side baffle 211. The bottom of the supporting plate 210 is rotatably connected to the bottom plate 20 through a rotating shaft. A clamping limit groove 2110 is provided inside the side baffle 211 for clamping the glass slide. The washing assembly is located at the upper part of the supporting assembly, including a connecting plate 30 connected to the vertical plate 10. A washing assembly corresponding to the supporting frame is arranged at the bottom of the connecting plate 30. Each washing assembly includes a mounting plate 3 10 and a flushing nozzle 311, the mounting plate 310 is connected to the connecting plate 30 through a connecting piece, the flushing nozzle 311 is equidistantly distributed along the length direction of the mounting plate 310, and is ball-connected to the mounting plate 310 through a ball joint 312, so that the flushing nozzle 311 can be adjusted in angle as needed to adapt to different flushing requirements; at the same time, due to the angle adjustment component set up, it includes a first angle adjustment piece and a second angle adjustment piece, which are respectively used to adjust the angle of the support frame and the flushing nozzle 311, and a linkage mechanism is provided between the two. When the flushing work is performed, the first angle adjustment piece and the second angle adjustment piece can be started synchronously to achieve precise adjustment of the angle of the support frame and the flushing nozzle 311, thereby improving the uniformity and effect of the flushing.

[0022] It should be understood that please refer to Figure 1 , as for the first angle adjustment member, it includes a first slide bar 410, a first limiting sleeve 411 and a first swinging rod 413. The first slide bar 410 is arranged along the length direction of the base plate 20 and is located on one side of the supporting frame. The first limiting sleeve 411 is symmetrically slidably sleeved on both ends of the length direction of the first slide bar 410, and the bottom of the first limiting sleeve 411 is connected to the top of the base plate 20. A plurality of first strip grooves corresponding to the supporting frames are opened on the rod body of the first slide bar 410. The first swinging rod 413 is arranged in a one-to-one correspondence with the plurality of supporting frames, and one end of each of the first swinging rods 413 is connected to the corresponding side baffle 211, and the other end is slidably embedded in the corresponding first strip groove 412.

[0023] In the specific implementation, the first sliding rod 410 slides along the length direction of the base plate 20 through the first limiting sliding sleeve 411, so that after the first sliding rod 410 slides, it drives the first strip groove 412 on its surface to move linearly. When the first strip groove 412 moves linearly, it can drive it to move the first swing rod 413 slidably embedded inside. Since one end of the first swing rod 413 is connected to the side baffle 211, and the side baffle 211 is installed at both ends of the supporting plate 210, and forms a supporting frame with the supporting plate 210, and the bottom of the supporting plate 210 is rotatably connected to the base plate 20 through a rotating shaft, the first swing rod 413 can drive the supporting frame to rotate back and forth on the base plate 20 through the rotating shaft (that is, swing along the length direction of the base plate 20) after the first strip groove 412 moves linearly, thereby realizing the adjustment of the angle of the supporting frame.

[0024] For the second angle adjustment, see Figure 2 and Figure 5 , which specifically includes a second slide bar 420, a second limiting sleeve 421 and a second swing rod 423. The second slide bar 420 is arranged at the bottom of the connecting plate 30 along the length direction of the connecting plate 30 and is located on one side of the flushing component. The second limiting sleeve 421 is symmetrically slidably sleeved at both ends of the length direction of the second slide bar 420, and the top of the second limiting sleeve 421 is connected to the bottom of the connecting plate 30. A plurality of second strip grooves 422 corresponding to the flushing components are opened on the rod body of the second slide bar 420. The second swing rod 423 is arranged in a one-to-one correspondence with the plurality of flushing components, and one end of each second swing rod 423 is connected to the corresponding flushing nozzle 311, and the other end is slidably embedded in the corresponding second strip groove 422.

[0025] Based on the above content, it can be known that the design and working principle of the second angle adjustment member disclosed in this embodiment are similar to those of the first angle adjustment member, so the principle will not be repeated in this embodiment. However, it should be noted that the second angle adjustment member proposed in this embodiment is different from the first angle condition in that it acts on a different component, namely the washing component rather than the support frame. That is to say, the second angle adjustment member realizes the angle adjustment of the washing nozzle 311 through the coordinated work of the second slide bar 420, the second limiting sleeve 421 and the second swing rod 423, so as to accurately control the injection direction and impact force of the washing liquid and further enhance the washing effect. In particular, when removing stubborn staining residues, the angle adjustment can provide a more targeted washing force, thereby ensuring the efficiency and uniformity of the washing nozzle 311 in the washing process of the glass slide.

[0026] Further, if Figure 4As shown, the ball connector 312 includes a spherical groove 3120 and a spherical body 3121. The spherical groove 3120 is opened inside the mounting plate 310 and corresponds one-to-one to the plurality of flushing nozzles 311. The spherical bodies 3121 are arranged one-to-one in the spherical groove 3120 and are adapted to the spherical groove 3120. The bottom of the spherical body 3121 is connected to the flushing nozzle 311 through a mounting seat.

[0027] In this embodiment, the spherical body 3121 is set in the spherical groove 3120 and adapted to the groove. This design allows the spherical body 3121 to rotate freely in the groove, thereby driving the flushing nozzle 311 connected to its bottom to perform multi-directional adjustments. The bottom of the spherical body 3121 is connected to the flushing nozzle 311 through a mounting seat. This connection method ensures that the flushing nozzle 311 can be stably fixed in the desired position while maintaining flexible rotation capabilities. Furthermore, in this embodiment, the direction of the flushing nozzle 311 is adjusted by the rotation of the spherical body 3121 in the spherical groove 3120, which allows the flushing nozzle to be accurately and freely adjusted in angle along the length and width directions of the connecting plate 30.

[0028] Furthermore, if Figure 1 and Figure 3 As shown, in this embodiment, a water storage tank 5 is further installed on the horizontal plate 11, and the water storage tank 5 is connected to the flushing nozzles 311 of the flushing assemblies through a flexible pipe 6. Through the water storage tank 5 and the flexible pipe 6, the flushing liquid stored in the water storage tank 5 is conveniently transported to the flushing nozzle 311 through the flexible pipe 6.

[0029] It should be understood that in the process of washing the glass slide, washing waste liquid is inevitably generated, and the prior art does not pay special attention to the washing waste liquid, so it is very easy to cause the washing waste liquid to remain and scatter everywhere, thereby polluting the environment and causing secondary pollution to the glass slide in serious cases. In view of this, this embodiment proposes a preferred implementation method to realize the recovery of the washing waste liquid. Specifically, Figure 3 As shown, a water channel 200 is opened on the bottom plate 20 along its length direction, one end of the water channel 200 is close to the horizontal plate 11, and the other end is inclined upward in the direction away from the horizontal plate 11; a hollow hole 100 is opened on the vertical plate 10 corresponding to the connection position between the water channel 200 and the vertical plate 10, and a water collecting funnel 7 is installed on the back side of the vertical plate 10 opposite to the water channel 200, the water collecting funnel 7 is set corresponding to the water channel 200, and the top of the water collecting funnel 7 is flush with the bottom opening of the hollow hole 100, and the bottom end thereof is connected to the waste liquid collection box 8 set on the base through a recovery pipe.

[0030] Based on the above embodiments, this solution constitutes an efficient waste liquid recovery system by jointly setting up a water guide groove 200 opened on the bottom plate 20 along its length direction, the corresponding hollow holes 100 on the vertical plate 10, and the water collecting funnel 7. The design of the water guide groove 200 is based on the drainage concept in fluid mechanics. By placing one end of the water guide groove 200 close to the horizontal plate 11 and tilting the other end upward, gravity is used to guide the flushing liquid to flow along the groove, thereby achieving effective collection and drainage of the flushing liquid, which not only reduces the splashing and overflow of the flushing liquid during the flushing process, but also avoids the pollution of the laboratory environment, and also reduces the risk of secondary contamination of the glass slide due to the residual flushing liquid. At the same time, a waste liquid collection box 8 is set, so that the waste liquid collected by the water collecting funnel 7 can be collected centrally, thereby realizing centralized treatment and recycling of the waste liquid, and reducing the environmental pollution and waste liquid treatment costs of the laboratory.

[0031] As a further preferred implementation method of this embodiment, specifically: Figure 2 and Figure 5 As shown, the second angle adjustment member also includes a guide block 424, a hemispherical groove 425 and a guide rod 426. The guide block 424 is arranged at the bottom of the connecting plate 30 and is located at one side of the spherical groove 3120. The hemispherical groove 425 is opened at the guide block 424 on the side facing the spherical groove 3120. The guide rod 426 is arranged at the upper part of the spherical body 3121. The upper part of the spherical body 3121 is provided with a connecting boss at the position passing through the spherical groove 3120. One end of the guide rod 426 is connected to the connecting boss, and the other end extends laterally and is in sliding contact with the hemispherical groove 425 through a sliding end located at its end.

[0032] In this embodiment, the guide block 424, the hemispherical groove 425 and the guide rod 426 are provided to enable the flushing nozzle 311 to achieve complex multi-directional angle adjustment; specifically, when the second angle adjustment member is working, the second slide bar 420 moves along the length direction of the connecting plate 30, and after the second slide bar 420 moves, it can drive the swing rod to swing inside it through the strip groove, and after the swing rod swings, it can drive the flushing nozzle 311 to swing back and forth along the length direction of the connecting plate 30, and when the flushing nozzle 311 swings, it can drive the swing rod to swing back and forth through the spherical groove 426. The body 3121 drives the guide rod 426 to move in the hemispherical groove 425. Due to the curved inner wall shape of the hemispherical groove 425, when the guide rod 426 moves on the inner wall of the hemispherical groove 425, the curved inner wall of the hemispherical groove 425 will generate a rotational torque around the center of the sphere on the guide rod 426, thereby prompting the guide rod 426 to push the spherical body 3121 to swing left and right in the spherical groove 3120, thereby making the angle adjustment of the washing nozzle 311 more flexible when washing the glass slide, and greatly enhancing the adaptability and convenience of the equipment.

[0033] Based on the above embodiment, the specific structure of the linkage structure is further described here. For details, please refer to Figure 6 The linkage mechanism includes a displacement plate 430 and a guide bevel 431. The displacement plate 430 is slidably arranged on the surface of the horizontal plate 11 along the length direction thereof. The guide bevel 431 is opened at both ends of the displacement plate 430 in the length direction and corresponds to the first slide bar 410 and the second slide bar 420 respectively. Moving blocks 432 are slidably arranged in the two guide bevel grooves 431. The two moving blocks 432 are respectively connected to the ends of the first slide bar 410 and the second slide bar 420. A tooth groove 433 is opened in the middle position of the displacement plate 430 along the length direction thereof. A half gear 434 is arranged inside the tooth groove 433. The half gear 434 is connected to the output end of the driving motor installed on the horizontal plate 11.

[0034] It should be noted here that the design principle of the linkage mechanism proposed in this embodiment is to achieve synchronous control of the first slide bar 410 and the second slide bar 420 through the interaction of the displacement plate 430, the guide bevel groove 431 and the moving block 432. Specifically, when the drive motor is powered on and started, its output end begins to rotate, thereby rotating the half gear 434, so that after the half gear 434 rotates, the displacement plate 430 is driven to reciprocate on the surface of the cross plate 11 through the tooth groove 433, so that after the displacement plate 430 reciprocates, it drives the guide bevel groove 431 to move. Since a moving block 432 is slidingly provided in the guide bevel groove 431, when the guide bevel groove 431 moves, the moving block 432 can move relative to the guide bevel groove 431, thereby prompting it to drive the first slide bar 410 and the second slide bar 420 to move linearly, so as to achieve synchronous start-up of the first angle adjustment member and the second angle condition to work.

[0035] It should be further explained here that, for the guide inclined groove 431 of the linkage mechanism, it mainly converts the vertical reciprocating movement of the displacement plate 430 into the horizontal movement of the first slide bar 410 and the second slide bar 420. Therefore, for the guide inclined groove 431, it is inclined on the displacement plate 430, that is, there is an angle between its axis and the central axis of the displacement plate 430 ( Figure 6 As shown, it is also necessary to explain that there are two ways to arrange the guide chute 431. One way is: the two sets of guide chute 431 are centrally symmetrical about the length center line of the displacement plate 430, and the two moving blocks 432 are respectively located on the same side of the guide chute 431 (such as Figure 6(a) shows), so that when the displacement plate 430 performs vertical reciprocating movement, it can respectively drive the first slide bar 410 and the second slide bar 420 to move in the same direction through the two sets of the guide inclined grooves 431 and the moving block 432, so that the first angle adjustment member and the second angle adjustment member drive the support frame and the flushing assembly to swing synchronously in the same direction, that is, when the support assembly swings forward along the length direction of the bottom plate 20, the flushing nozzle 311 swings forward along the length direction of the connecting plate 30, as shown in FIG. Figure 7 As shown; Another way is that the two groups of guide slots 431 are symmetrical about the length center line of the displacement plate 430. In this case, the two moving blocks 432 are respectively located on different sides of the guide slots 431 (such as Figure 6 (b)), so that when the displacement plate 430 performs vertical reciprocating movement, it can drive the first slide bar 410 and the second slide bar 420 to move in the opposite direction through the two groups of the guide inclined grooves 431 and the moving block 432, so that the first angle adjustment member and the second angle adjustment member drive the support frame and the flushing assembly to swing in the opposite direction synchronously, that is, when the support assembly swings backward along the length direction of the bottom plate 20, the flushing nozzle 311 swings forward along the length direction of the connecting plate 30, as shown in FIG. Figure 8 As shown; it should be noted that the above-mentioned directional words such as front and back are all attached Figure 1 The reference, that is, the left side of the base is the forward direction, and the right side of the base is the backward direction.

[0036] Based on the above embodiment, a plurality of extruded rubber blocks are equidistantly arranged on both sides of the clamping limit groove 2110. The extruded rubber blocks facilitate the user to clamp and fix the glass slide when inserting the glass slide into the clamping limit groove 2110, and can protect the glass slide to a certain extent.
