Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a multi-model slide staining rack for pathology. Background Technology

[0002] Staining pathological sections is a crucial step in clinical pathological diagnosis. It requires a specialized device to fix the pathological tissue sections and immerse them in a staining solution to reveal the color of the tissue cell structure. This provides physicians with a basis for observing lesion characteristics and making a clear diagnosis. During this process, the section-carrying device must ensure that the sections are stably fixed and that the sample area is evenly contacted with the staining solution.

[0003] In clinical pathology examinations, tissue sections come in various widths and lengths depending on the sample type and examination requirements. Larger sections maintain sample integrity and facilitate comprehensive observation of lesion relationships, while smaller sections are suitable for routine batch testing. Different section sizes require corresponding staining and fixation protocols to ensure staining effectiveness and diagnostic accuracy.

[0004] Existing staining devices lack the ability to adapt to different sized sections and cannot automatically adjust the clamping state according to the section width, which can easily lead to problems such as insecure fixation or excessive clamping that damages the sections. At the same time, the height of the device cannot flexibly adapt to the soaking requirements of sections of different lengths, resulting in large sections being missed in staining and small sections being over-soaked, which affects staining quality and diagnostic efficiency. Summary of the Invention

[0005] This invention provides a multi-model slide staining rack for pathology departments to solve the problems of existing staining devices lacking adaptability to slides of different sizes, failing to automatically adjust the clamping state according to the slide width, easily resulting in insecure fixation or excessive clamping that damages the slides, and the device height not being able to flexibly adapt to the soaking requirements of slides of different lengths, leading to unstained large slides and over-soaking of small slides, affecting staining quality and diagnostic efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A multi-model slide staining rack for pathology includes a lower cannula assembly, an upper cannula assembly, and two support rods. The two ends of the lower cannula assembly are fixed to the two support rods via locking components, while the two ends of the upper cannula assembly are slidably connected to the two support rods via locking components. A connecting component connects the upper and lower cannula assemblies. A height adjustment component is provided within each support rod to adjust the distance between the two cannula assemblies. Adaptive clamping components are provided on both sides of each cannula assembly to hold slides, and a counting component is provided on the adaptive clamping component to display the total number of slides.

[0008] The spacing between the two adaptive clamping components on either side of a sleeve assembly is adaptively adjusted according to the width of the glass slide.

[0009] Optionally, the sleeve assembly includes multiple sleeves, with the number of sleeves in two sleeve assemblies being equal. Each sleeve in the upper sleeve assembly corresponds one-to-one with each sleeve in the lower sleeve assembly. The adaptive clamping assembly includes a first sliding cavity, with the first sliding cavity respectively opened at both ends of the sleeve. One end of a first spring is connected to the inner wall of the first sliding cavity, and a first movable rod is fixedly installed at the other end of the first spring. A clamping frame is connected to the end of the first movable rod. The number of sleeves is even. Starting with the sleeve at the end of the sleeve assembly, the same side ends of every two adjacent sleeves are connected to the same clamping frame through the corresponding first movable rod. The clamping frame has a clamping groove located between two sleeves. An inclined first guide plate is installed on the clamping frame. The first guide plate has a guide groove that corresponds to and fits the clamping groove. The bottom end of the guide groove communicates with the clamping groove.

[0010] Optionally, the adaptive clamping assembly includes a second sliding cavity, which is formed on the clamping frame and located on both sides of the clamping groove. One end of a second spring is connected to the inner wall of the second sliding cavity, and a second movable rod is installed on the other end of the second spring. Clamping pieces are provided at the ends of the two second movable rods that are close to each other on the clamping frame. An inclined second guide plate is connected to the top of the clamping piece. The two second guide plates are symmetrical with respect to the vertical direction. The second guide plates are adapted to the guide groove. Protective pads are installed on the sides of the two clamping pieces that are close to each other.

[0011] Optionally, the connecting assembly includes a first connecting block. In the lower sleeve group, the top ends of the two middle and adjacent sleeves in the four sleeves of the two adjacent clamping frames are jointly installed with the same first connecting block. In the upper sleeve group, the bottom ends of the two middle and adjacent sleeves in the four sleeves of the two adjacent clamping frames are jointly installed with the same second connecting block. The second connecting block is slidably connected to the corresponding first connecting block below.

[0012] Optionally, the locking assembly includes a fixing block and a slider. In the lower sleeve assembly, the sleeves at both ends are fixedly connected to two support rods via the fixing block, and in the upper sleeve assembly, the sleeves at both ends are slidably connected to two support rods via the slider.

[0013] Optionally, a locking bolt is threaded onto the slider, and when the locking bolt is tightened, the locking bolt abuts against the support rod.

[0014] Optionally, the height adjustment assembly includes a movable block slidably mounted inside a support rod. The bottom end of the movable block extends outside the support rod, and a support plate is connected to the bottom end of the movable block. A connecting plate is connected to the top end of the movable block. One side of the connecting plate connected to the movable block is slidably connected inside the support rod, and the other side of the connecting plate extends outside the support rod and downwards. The two sides of the connecting plate are parallel to each other, and the bottom end of the connecting plate on the side outside the support rod is connected to the slider.

[0015] Optionally, a suction cup is installed on the bottom surface of the support plate.

[0016] Optionally, the counting component includes a micro display screen and a sensor. The micro display screen is mounted on a support rod, and the sensor is mounted in the first sliding cavity. The sensor is electrically connected to the micro display screen.

[0017] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0018] In the above scheme, the first sliding cavity provides sliding guide space for the first movable rod. When the first spring is in its natural state, it drives the first movable rod and the clamping frame to maintain the initial clamping distance. When the slide is inserted from top to bottom, the bottom of the slide contacts the inclined first guide plate. As the slide continues to be inserted downward, it drives the first guide plate and the clamping frame to move away from the sleeve, pushing the first movable rod to slide outward along the first sliding cavity. The first spring is stretched and generates a reverse elastic force. The clamping groove provides insertion and positioning space for the slide, ensuring that the slide is placed vertically. When the slide is inserted into the clamping groove at the high point and the low point in sequence, the installation is completed. This achieves the effect of adaptive clamping according to different slide widths, improving slide loading efficiency. At the same time, the double-layer design ensures that the slide maintains a stable posture during the staining process, reducing the impact of the staining solution flow on the slide.

[0019] The guide groove and the clamping groove work together. During slide insertion, the edge of the slide first contacts the inclined surface of the guide groove. The guide groove guides the slide gradually to the center of the clamping groove through the guiding action of the inclined surface, avoiding deviation or jamming during slide insertion. Even if the operator's movements are not precise enough when loading the slide, the guide groove can correct the insertion direction of the slide, ensuring that the slide and the clamping groove are accurately aligned. This makes the clamping force of the clamping frame evenly distributed on both sides of the slide, preventing the slide from breaking or shifting due to uneven force, making the slide more firmly clamped, and further improving the convenience of slide loading and clamping stability.

[0020] The height adjustment component can adjust the overall height of the device according to the length of the slide, so that the sample area of ​​slides of different lengths can be precisely at the optimal immersion depth. This prevents large slides from being missed due to insufficient height, and avoids small slides from being over-immersed due to excessive height, significantly improving staining adaptability and consistency of staining effect.

[0036] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 7As shown, an embodiment of the present invention provides a multi-model slide staining rack for pathology, comprising two cannula groups arranged at opposite heights. Each cannula group includes multiple cannulas 10. Each cannula 10 in the upper cannula group corresponds one-to-one with each cannula 10 in the lower cannula group. A connecting component 30 connects the corresponding upper and lower cannulas 10. The cannulas 10 at both ends of a cannula group are connected to support rods 11 via locking components 10. The support rods 11 connected to the corresponding upper and lower cannulas 10 on the same side are the same. An adaptive clamping component 20 is provided on the cannulas 10, which is used to adaptively clamp and fix the slide to the width.

[0038] The height adjustment component 50 is disposed inside the support rod 11. The height adjustment component 50 is used to adjust the height of the device according to glass slides of different lengths, so as to adapt to the optimal immersion position of glass slides of different lengths.

[0039] This dyeing rack consists of two sets of sleeves at different heights forming a basic support frame. Multiple sleeves 10 are connected by connecting components 30 to form a stable multi-row clamping structure. The sleeves 10 at both ends are fixed to the support rods 11 by means of locking components 40 to ensure the stability of the overall structure.

[0040] The adaptive clamping component 20 can automatically adjust the clamping state according to glass slides of different widths, eliminating the need for manual width adjustment. This enables adaptive clamping of glass slides of various widths and avoids the problem of unstable fixation due to differences in glass slide width.

[0041] The height adjustment component 50 can adjust the overall height of the device according to the length of the slide, so that the sample area of ​​slides of different lengths can be precisely at the optimal immersion depth. This prevents large slides from being missed due to insufficient height and avoids small slides from being over-immersed due to excessive height, significantly improving staining adaptability and consistency of staining effect.

[0042] like Figure 1 and Figure 4 As shown, the adaptive clamping assembly 20 includes a first sliding cavity 21. The sleeve 10 has a first sliding cavity 21 at each end. A first spring 23 is fixedly installed on the inner wall of the first sliding cavity 21. A first movable rod 22 is fixedly installed at the end of the first spring 23 away from the first sliding cavity 21. The first movable rod 22 is slidably connected to the inner wall of the first sliding cavity 21. A clamping frame 24 is fixedly installed on the first movable rod 22. A clamping groove 25 is provided on the clamping frame 24. A first guide plate 26 is fixedly installed on the clamping frame 24. The first guide plate 26 is inclined, i.e., it forms an angle with the clamping frame 24. The first guide plates 26 at both ends of the same sleeve 10 are symmetrically arranged.

[0043] Starting with the sleeve 10 at the end of the sleeve assembly, two adjacent sleeves 10 are connected to the same clamping frame 24 on the same side. Two sleeves 10 are connected to one clamping frame 24, and a clamping groove 25 is located between the two sleeves 10 on one clamping frame 24. A guide groove 27 is provided on the first guide plate 26. The position of the guide groove 27 corresponds to the clamping groove 25, that is, the bottom end of the guide groove 27 is connected to the clamping groove 25, and the width of the clamping groove 25 is equal to the width of the guide groove 27. The two clamping frames 24 arranged opposite each other at both ends of the same sleeve 10 are symmetrical, that is, the guide groove 27 and the clamping groove 25 on the opposite clamping frames 24 are also symmetrical to each other.

[0044] The first sliding cavity 21 provides a sliding guide space for the first movable rod 22. When the first spring 23 is in its natural state, it drives the two opposing first movable rods 22 and the two opposing clamping frames 24 to maintain the initial clamping distance. When the glass slide is inserted from top to bottom, the bottom of the glass slide contacts the inclined first guide plate 26. As the glass slide continues to be inserted downward, the first guide plate 26 drives the clamping frame 24 to move away from the sleeve 10, pushing the first movable rod 22 to slide outward along the first sliding cavity 21. The first spring 23 is stretched and generates a reverse elastic force. The glass slide is inserted along the position of the clamping groove 25. The positions of the upper sleeve 10 and the clamping frame 24 connected to the lower sleeve 10 also correspond, and the positions of the clamping grooves 25 on the upper and lower corresponding clamping frames 24 correspond.

[0045] The clamping groove 25 provides space for inserting and positioning the slide, ensuring that the slide is placed vertically. The installation is completed when the slide is inserted into the clamping groove 25 at the high point and the low point in sequence. This achieves the effect of adaptive clamping according to different slide widths, improving the efficiency of slide loading. At the same time, the double-layer design ensures that the slide maintains a stable posture during the staining process, reducing the impact of the staining solution flow on the slide.

[0046] like Figure 4 As shown, the first guide plate 26 has a guide groove 27, which cooperates with the clamping groove 25.

[0047] The guide groove 27 and the clamping groove 25 work together. During the slide insertion process, the edge of the slide first contacts the inclined surface of the guide groove 27. The guide groove 27 guides the slide gradually to the center position of the clamping groove 25 through the guiding effect of the inclined surface, avoiding the slide from being skewed or stuck during insertion. Even if the operator's actions are not precise enough when loading the slide, the guide groove 27 can correct the insertion direction of the slide, ensuring that the slide and the clamping groove 25 are accurately aligned. This makes the clamping force of the clamping frame 24 evenly distributed on both sides of the slide, preventing the slide from being damaged or shifted due to uneven force, and further improving the convenience of slide loading and clamping stability.

[0048] The adaptive clamping assembly 20 further includes a second sliding cavity 28, which is formed on the clamping frame 24 and located on both sides of the clamping groove 25 and communicates with the clamping groove 25. A second spring 213 is fixedly installed on the inner wall of the second sliding cavity 28. A second movable rod 29 is fixedly installed at the end of the second spring 213 away from the second sliding cavity 28. The second movable rod 29 is slidably connected to the second sliding cavity 28. Clamping pieces 210 are fixedly installed at the ends of the two second movable rods 29 that are close to each other. A second guide plate 211 that cooperates with the guide groove 27 is fixedly installed at the top of the clamping piece 210. The second guide plates 211 are inclined, and two adjacent second guide plates 211 are symmetrically arranged. The two second guide plates 211 are inclined in a direction away from each other.

[0049] The second sliding cavity 28 provides a sliding path for the second movable rod 29. The second spring 213 is always in an extended state. When glass slides of different thicknesses are inserted into the clamping groove 25 along the second guide plate 211, the glass slides are located between the two clamping pieces 210. The second spring 213 generates a corresponding compression amount according to the thickness of the glass slide, thereby forming a clamping force adapted to the thickness of the glass slide. When a thin glass slide is inserted, the compression amount of the second spring 213 is small, and the clamping force is gentle, avoiding damage to the glass slide; when a thick glass slide is inserted, the compression amount of the second spring 213 is large, and the clamping force is enhanced, ensuring stable clamping without loosening. The second guide plate 211 cooperates with the guide groove 27 to guide the glass slides accurately into the clamping pieces 210, improving the efficiency of slide loading.

[0050] Protective pads 212 are fixedly installed on the sides of the two clamping plates 210 that are close to each other. The protective pads 212 are used to protect the glass slide and enhance the clamping stability.

[0051] The protective pad 212 on the opposite side of the clamping slide 210 directly contacts the edge of the slide (non-sample area). The protective pad 212 is made of a soft and elastic material, which can isolate the clamping slide 210 from hard contact with the slide, and prevent the metal clamping slide 210 from scratching the surface of the slide or damaging the anti-detachment film on the slide. This effectively protects the slide and the pathological sample on the slide. At the same time, the elastic deformation of the protective pad 212 can increase the contact area with the edge of the slide and improve the surface friction. Even when the staining solution is flowing or the staining rack is slightly shaken, the slide can be firmly fixed and prevent the slide from shifting or tilting. In addition, the protective pad 212 can also compensate for the small dimensional deviations of different slide edges, ensuring the tightness of the clamping, further enhancing the clamping stability, and reducing the problem of uneven staining caused by the loosening of the slide during the staining process.

[0052] like Figure 2 As shown, the connecting assembly 30 includes a first connecting block 31 fixedly installed at the top of the low-point sleeve 10, a second connecting block 32 slidably installed inside the top of the first connecting block 31, and the second connecting block 32 fixedly installed at the bottom of the high-point sleeve 10.

[0053] The first connecting block 31 and the second connecting block 32 form a sliding fit structure. The first connecting block 31 on the low-position sleeve 10 provides sliding support and guidance for the second connecting block 32 on the high-position sleeve 10. In one embodiment, among the four sleeves 10 in two adjacent clamping frames 24, the two middle and adjacent sleeves 10 are connected to the same connecting component 30. That is, two low-position sleeves 10 are connected to the first connecting block 31, and two high-position sleeves 10 are connected to the second connecting block 32. On the same horizontal plane, multiple clamping frames 24 located on the same side are arranged in a straight line, with their ends touching each other. That is, when the sleeve 10 at the end moves, since the two middle sleeves 10 in the four sleeves 10 of the adjacent clamping frames 24 share a connecting component 30, the remaining sleeves 10 on the same horizontal plane move accordingly.

[0054] Specifically, among the four sleeves 10 of the two adjacent clamping frames 24 in the lower sleeve group, the two middle and adjacent sleeves 10 are connected to a first connecting block 31. Among the four sleeves 10 of the two adjacent clamping frames 24 in the upper sleeve group, the two middle and adjacent sleeves 10 are connected to a second connecting block 32. The second connecting block 32 is slidably connected to the first connecting block 31.

[0055] No connecting components 30 are provided on the sleeves 10 located at both ends of the sleeve group.

[0056] When the height adjustment component 50 drives the device to adjust its height, the high-point sleeve 10 will move up and down with the adjustment action. At this time, the second connecting block 32 slides along the inside of the first connecting block 31 to ensure that the relative positions between the sleeves 10 corresponding to the high and low points are stable. This avoids the sleeves 10 from shifting or the frame from deforming due to height adjustment, ensuring the integrity of the multi-layer structure formed by multiple sets of sleeves 10. It also provides flexible space for height adjustment, so that the device always maintains structural stability during the height adjustment process and will not shake or loosen. This ensures that the clamping stability of the glass slide is not affected by the height adjustment.

[0057] like Figures 5 to 7As shown, the locking assembly 40 includes a fixing block 43 and a slider 41. Fixing blocks 43 are connected to the two sleeves 10 at both ends of the lower sleeve assembly, and the two fixing blocks 43 are fixedly connected to the two support rods 11. Slider blocks 41 are connected to the two sleeves 10 at both ends of the upper sleeve assembly, and the two sliders 41 are slidably connected to the two support rods 11. That is, the two support rods 11 on both sides of the sleeve assembly are each fixedly equipped with a fixing block 43 and slidably equipped with a slider 41, with the slider 41 positioned above the fixing block 43. A locking bolt 42 is threaded onto the slider 41, and the locking bolt 42 is located at the center of one side of the slider 41. Tightening the locking bolt 42 causes it to abut against the support rod 11.

[0058] The fixing block 43 fixes the end sleeve 10 at the lower position to the support rod 11, forming a fixed support base point for the device, ensuring the stability of the position of the end sleeve 10 at the lower position. The end sleeve 10 at the higher position is slidably connected to the support rod 11 through the slider 41. The slider 41 can slide up and down along the support rod 11, driving the high-point sleeve 10 to move synchronously, realizing the initial adjustment of the device height. When the height is adjusted to the appropriate position, the locking bolt 42 is tightened. The locking bolt 42 is located in the center of one side of the slider 41 and abuts tightly against the support rod 11. The position of the slider 41 is locked by the friction between the locking bolt 42 and the support rod 11, thereby fixing the height of the high-point sleeve 10. This adapts to glass slides of different lengths and ensures the stability of the device.

[0059] like Figure 5 and Figure 6 As shown, the height adjustment assembly 50 includes a movable block 51 slidably installed inside the support rod 11. A support plate 52 is fixedly installed at the bottom end of the movable block 51, perpendicular to the movable block 51, with the movable block 51 located at the center of the top surface of the support plate 52. A connecting plate 53 is fixedly installed at the top end of the movable block 51. The connecting plate 53 has an inverted U-shaped structure with an opening facing downwards and one side wall shorter than the other. The longer side wall of the connecting plate 53 is connected to the top end of the movable block 51, and the end of the connecting plate 53 away from the movable block 51 (i.e., the shorter side wall) is fixedly connected to the slider 41. The shorter side wall of the connecting plate 53 protrudes outside the support rod 11. The longer side wall of the connecting plate 53 and the upper part of the movable block 51 are located inside the support rod 11, and the longer and shorter side walls of the connecting plate 53 are parallel. The bottom of the movable block 51 extends to the outside of the bottom of the support rod 11, and the support plate 52 is located outside the support rod 11.

[0060] When adjusting the height of slider 41 according to the slide length, sliding slider 41 will drive connecting plate 53 to move together. When connecting plate 53 moves, it will drive movable block 51 and support plate 52 to move relative to support rod 11. Support plate 52 will drive suction cup 70 to move, realizing the adjustment of the distance between the upper and lower sleeve groups, realizing the simultaneous adjustment of the device height, and ensuring that the position of the slide sample area of ​​different sizes is adapted to the staining solution. After adjusting the distance between the upper and lower sleeve groups, the suction cup 70 is connected to the bottom of the container to install the entire device.

[0061] like Figures 1 to 6 As shown, a suction cup 70 is fixedly installed on the lower surface of the support plate 52 for adhering to the bottom wall of the container.

[0062] When the device is placed in the dyeing container, the suction cup 70 on the lower surface of the support plate 52 contacts the bottom wall of the container. The air inside the suction cup 70 is squeezed out, forming a negative pressure state, which makes the suction cup 70 firmly adhere to the bottom wall of the container, thereby fixing the entire dyeing rack in the container. This can effectively prevent the dyeing rack from shifting or tipping over due to the flow of dye liquor, the operator moving the dyeing rack, or other external forces during the dyeing process, ensuring that the dyeing rack is always in a stable placement state.

[0063] like Figures 1 to 5 As shown, a counting component 60 is provided on the support rod 11. The counting component 60 includes a miniature display screen 62 fixedly installed on the support rod 11. A sensor 61 is fixedly installed in the first sliding cavity 21. The sensor 61 is electrically connected to the miniature display screen 62.

[0064] Sensor 61 is a miniature switch sensor installed in the first sliding cavity 21. It can detect the movement of the first movable rod 22 in real time. When the first movable rod 22 is detected to move and stretch the first spring 23, sensor 61 converts the detected signal into an electrical signal and transmits it to the miniature display screen 62. The miniature display screen 62 displays the total number of slides intuitively. Operators can quickly understand the number of slides loaded on the staining rack through the miniature display screen 62 without manual counting, reducing counting errors and improving work efficiency.

[0065] Figure 1 and Figure 2 In the diagram, the adaptive clamping assembly 20 is not fully shown. To facilitate understanding and avoid obstruction, the first guide plate 26 at one end of the sleeve 10 is not shown.

[0066] The working process of the multi-model slide staining rack for pathology provided by this invention is as follows:

[0067] This dyeing rack has a basic support frame consisting of two sets of sleeves at different heights. Multiple sets of sleeves 10 are connected by connecting components 30 to form a stable multi-row clamping structure. The sleeves 10 at both ends of the sleeve set are installed on the support rod 11 with the help of locking components 40 to ensure the stability of the overall structure.

[0068] The support rod 11 is installed on the support device or a support point is provided for the support rod 11. The slider 41 is adjusted according to the length of the glass slide, so that the slider 41 drives the movable block 51, the support plate 52 and the suction cup 70 to move relative to the support rod 11 through the connecting plate 53, thereby adjusting the distance between the upper and lower sleeve groups. When the distance is appropriate, the locking bolt 42 is tightened so that the locking bolt 42 abuts against the support rod 11 to fix the position of the slider 41 and the upper sleeve group. During the movement of the slider, since the end sleeve 10 of the upper sleeve group is connected to the slider 41 and can move with the slider 41, and since the sleeve 10 is connected to the clamping frame 24, the two middle sleeves 10 of the four sleeves 10 of the two adjacent clamping frames 24 share a connecting component 30. Therefore, the remaining sleeves 10 move with the end sleeves 10. Since the bottom end of the upper sleeve 10 is equipped with a second connecting block 32, the second connecting block 32 is slidably connected to the first connecting block 31. During the movement of the upper sleeve group, the second connecting block 32 slides relative to the first connecting block 31. The height adjustment component 50 can adjust the overall height of the device according to the length of the slide, so that the sample area of ​​slides of different lengths can be precisely at the optimal immersion depth. This prevents large slides from being missed due to insufficient height and avoids small slides from being over-immersed due to excessive height, significantly improving staining adaptability and consistency of staining effect.

[0069] After adjusting the distance between the upper and lower sleeve groups, connect the suction cup 70 to the bottom of the container to fix the entire device. Guide the glass slide along the guide groove 27 of the upper sleeve group and insert it between the two opposing clamping pieces 210. Continue to push the glass slide so that the lower part of the glass slide is inserted between the two opposing clamping pieces 210 of the lower sleeve group, and the upper part of the glass slide is inserted between the two opposing clamping pieces 210 of the upper sleeve group. During this process, the glass slide will push the second movable rod 29 due to its thickness. Due to the buffer of the second spring 213, the second movable rod 29 will clamp the glass slide with appropriate force through the clamping pieces 210. Since the glass slides have different widths and the clamping pieces 210 are connected to the clamping frame 24, the clamping frame 24 will be pushed during the insertion process, causing the first movable rod 22 to slide relative to the sleeve 10. Adjust the distance between the two opposing clamping frames 24 to adapt to the width of the glass slide. The adaptive clamping component 20 can automatically adjust the clamping state according to glass slides of different widths, eliminating the need for manual width adjustment. This enables adaptive clamping of glass slides of various widths and avoids the problem of unstable fixation due to differences in glass slide width.

[0070] Sensor 61 is installed in the first sliding cavity 21 and can detect the movement of the first movable rod 22 in real time. When the first movable rod 22 is detected to move and stretch the first spring 23, sensor 61 converts the detected signal into an electrical signal and transmits it to the micro display screen 62. The micro display screen 62 displays the total number of slides intuitively. Operators can quickly understand the number of slides loaded on the staining rack through the micro display screen 62 without manual counting, reducing counting errors and improving work efficiency.

[0071] The first sliding cavity 21 provides a sliding guide space for the first movable rod 22. When the first spring 23 is in its natural state, it drives the first movable rod 22 and the clamping frame 24 to maintain the initial clamping distance. When the slide is inserted from top to bottom, the bottom of the slide contacts the inclined first guide plate 26. As the slide continues to be inserted downward, it drives the first guide plate 26 and the clamping frame 24 to move away from the sleeve 10, pushing the first movable rod 22 to slide outward along the first sliding cavity 21. The first spring 23 is stretched and generates a reverse elastic force. The clamping groove 25 provides an insertion and positioning space for the slide, ensuring that the slide is placed vertically. When the slide is inserted into the clamping groove 25 at the high point and the low point in sequence, the installation is completed. This achieves the effect of adaptive clamping according to different slide widths, improving the slide loading efficiency. At the same time, the double-layer design ensures that the slide maintains a stable posture during the staining process, reducing the impact of the staining solution flow on the slide.

[0072] The guide groove 27 and the clamping groove 25 work together. During the slide insertion process, the edge of the slide first contacts the inclined surface of the guide groove 27. The guide groove 27 guides the slide gradually to the center position of the clamping groove 25 through the guiding effect of the inclined surface, avoiding the slide from being skewed or stuck during insertion. Even if the operator's actions are not precise enough when loading the slide, the guide groove 27 can correct the insertion direction of the slide, ensuring that the slide and the clamping groove 25 are accurately aligned. This makes the clamping force of the clamping frame 24 evenly distributed on both sides of the slide, preventing the slide from being damaged or shifted due to uneven force, and further improving the convenience of loading the slide and the stability of clamping.

[0073] The second sliding cavity 28 provides a sliding path for the second movable rod 29. The second spring 213 is always in an extended state. When glass slides of different thicknesses are inserted into the clamping groove 25 along the second guide plate 211, the second spring 213 generates a corresponding compression amount according to the thickness of the glass slide, thereby forming a clamping force adapted to the thickness of the glass slide. When a thin glass slide is inserted, the compression amount of the second spring 213 is small, and the clamping force is gentle, avoiding damage to the glass slide; when a thick glass slide is inserted, the compression amount of the second spring 213 is large, and the clamping force is enhanced, ensuring stable clamping without loosening. The second guide plate 211 cooperates with the guide groove 27 to guide the glass slide to accurately enter between the clamping plates 210, improving the efficiency of slide loading.

[0074] The protective pad 212 on the opposite side of the clamping slide 210 directly contacts the edge of the slide (non-sample area). The protective pad 212 is made of a soft and elastic material, which can isolate the clamping slide 210 from hard contact with the slide, and prevent the metal clamping slide 210 from scratching the surface of the slide or damaging the anti-detachment film on the slide. This effectively protects the slide and the pathological sample on the slide. At the same time, the elastic deformation of the protective pad 212 can increase the contact area with the edge of the slide and improve the surface friction. Even when the staining solution is flowing or the staining rack is slightly shaken, the slide can be firmly fixed and prevent the slide from shifting or tilting. In addition, the protective pad 212 can also compensate for the small dimensional deviations of different slide edges, ensuring the tightness of the clamping, further enhancing the clamping stability, and reducing the problem of uneven staining caused by the loosening of the slide during the staining process.

[0075] The first connecting block 31 and the second connecting block 32 form a sliding fit structure. The first connecting block 31 on the low-point sleeve 10 provides sliding support and guidance for the second connecting block 32 on the high-point sleeve 10. When the height adjustment component 50 drives the device to adjust its height, the high-point sleeve 10 will move up and down with the adjustment action. At this time, the second connecting block 32 slides along the inside of the first connecting block 31 to ensure the relative position between the high and low point sleeves 10 is stable. This avoids the sleeve 10 from shifting or the frame from deforming due to height adjustment, ensuring the integrity of the multi-layer structure formed by multiple sets of sleeves 10. It also provides flexible space for height adjustment, so that the device always maintains structural stability during the height adjustment process and will not shake or loosen. This ensures that the clamping stability of the glass slide is not affected by the height adjustment.

[0076] The fixing block 43 fixes the outermost sleeve 10 at the low point to the support rod 11, forming a fixed support base point for the device, ensuring the stability of the low point sleeve 10. The outermost sleeve 10 at the high point is slidably connected to the support rod 11 through the slider 41. The slider 41 can slide up and down along the support rod 11, driving the high point sleeve 10 to move synchronously, realizing the initial adjustment of the device height. When the height is adjusted to the appropriate position, the locking bolt 42 is tightened. One end of the locking bolt 42 located inside the slider 41 is tightly abutted against the support rod 11. The position of the slider 41 is locked by the friction between the bolt and the support rod 11, thereby fixing the height of the high point sleeve 10. This adapts to glass slides of different lengths and ensures the stability of the device.

[0077] When adjusting the height of slider 41 according to the length of the slide, sliding slider 41 will drive connecting plate 53 to move together. When connecting plate 53 moves, it will drive movable block 51 and support plate 52 to move together, so as to realize the simultaneous adjustment of the height of the device and ensure that the position of the slide sample area of ​​different sizes is adapted to the staining solution.

[0078] When the device is placed in the dyeing container, the suction cup 70 on the lower surface of the support plate 52 contacts the bottom wall of the container. The air inside the suction cup 70 is squeezed out, forming a negative pressure state, which makes the suction cup 70 firmly adhere to the bottom wall of the container, thereby fixing the entire dyeing rack in the container. This can effectively prevent the dyeing rack from shifting or tipping over due to the flow of dye liquor, the operator moving the dyeing rack, or other external forces during the dyeing process, ensuring that the dyeing rack is always in a stable placement state.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
