Description

Technical Field

[0001] The present invention relates to the technical field of pathological section processing, and particularly relates to a storage rack for pathological tissue sections and a staining processing device. Background Art

[0002] In the field of modern medical diagnosis, the production and staining processing of pathological sections play a crucial role. The acquisition of pathological sections usually goes through a series of delicate steps. Medical staff need to precisely excise the diseased part of the patient, then preserve it with paraffin, and then make it into thin slices. The key step after slicing is to dip the sample with a glass slide, and only after staining processing can the pathological section play an actual role in disease diagnosis, providing doctors with intuitive and accurate cell morphology and pathological feature information to assist in accurately diagnosing the condition.

[0003] With the continuous growth of medical needs, especially in the case of dealing with a large number of pathological sections, improving the processing ability and efficiency of section staining has become an urgent problem to be solved. In past technical explorations, many inventions have emerged. For example, the patent with the application number CN202411103647.7 discloses a pathological tissue section staining device, and the patent with the application number CN202321835543.6 discloses a pathological section staining device. These two patent technologies show a common design idea, that is, arranging multiple containers filled with different staining solutions in a circumferential direction, placing the glass slides carrying pathological sections on a dedicated staining rack, and then the staining rack sequentially shuttles between the containers filled with specific solutions in a predetermined order. Through this orderly flow, multi-step staining of pathological sections is achieved, meeting the needs of batch processing of pathological sections and dealing with complex staining process flows, and enabling the efficient advancement of large-scale pathological diagnosis work.

[0004] However, when the scenario changes to a laboratory environment, the situation is different. In a laboratory, it is often the case that only a small number of pathological sections need to be processed, and the involved staining processes may be relatively few and the operation procedures are relatively simple. At this time, those devices customized for large-scale and complex staining processes expose many drawbacks. From the perspective of the device structure, in order to achieve the automated transfer of multiple containers and multiple processes, it is equipped with complex mechanical transmission components, precise positioning devices, and complex control systems, with an intricate internal structure; in terms of volume, due to the need to accommodate numerous containers and ensure smooth operating space for the staining brackets, the overall volume of the device is huge, occupying a large amount of precious space in the laboratory; from the cost perspective, the complex structural design, the selection of high-precision components, and the high investment in the R & D process directly lead to high manufacturing costs, and the later maintenance and servicing costs cannot be underestimated either. This undoubtedly increases the operating costs and burdens of the laboratory, making the applicability of these devices greatly reduced when dealing with simple staining tasks for a small number of sections in a small laboratory.

[0005] In summary, in the daily work of laboratories and some small medical institutions and laboratories that are sensitive to costs and space, there is an urgent need for a pathological tissue section staining processing solution that can not only meet the needs of simple staining processes but also overcome the problems of complex structure, large volume, and high cost of existing large and complex staining devices. This also becomes an important opportunity and starting point for the research and development of this patent. Summary of the Invention

[0006] In view of the problems pointed out in the background art, the present invention proposes a storage rack for pathological tissue sections and a staining processing device, which has a simple structure, a small volume, a low cost, is suitable for manual staining processing, and is convenient for cleaning to avoid cross-contamination between staining solutions.

[0007] The technical solution of the present invention is realized as follows: A storage rack for pathological tissue sections includes a rack body. A number of slots are provided on the rack body. A horizontally arranged cleaning plate is connected to the upper side of the rack body. Insertion openings corresponding to the slots are provided on the cleaning plate. A water leakage groove I is provided on the side wall of the insertion opening. A number of water leakage holes are distributed on the cleaning plate.

[0008] The present invention is further configured such that the rack body is a U-shaped structure with an upward opening. The two ends of the rack body are fixedly connected to the cleaning plate. The slots are provided on the upper side surface of the middle part of the rack body.

[0009] The present invention is further configured such that a U-shaped handle with a downward opening is connected to the upper side of the cleaning plate.

[0010] The present invention is further configured such that both ends of the handle are rotatably connected to the cleaning plate, and further includes an elongated driving bar. Both ends of the driving bar are movably connected to both sides of the handle, and a plurality of driving arms extending downward are provided at intervals along the length direction on the lower side of the driving bar.

[0011] The present invention is further configured such that connecting shafts are respectively provided at both ends of the driving bar, and movable slots connected to the connecting shafts are provided on the handle. The movable slots are arranged in the up-down direction.

[0012] The present invention is further configured such that a plurality of water leakage grooves II are provided along the circumferential direction of the edge of the cleaning plate.

[0013] The present invention is further configured such that vertical plates corresponding to both sides of the handle are vertically provided on the cleaning plate. The vertical plates are arranged at intervals with the handle. Connecting grooves connected to the connecting shafts are provided on the vertical plates, and a spring is sleeved on the connecting shaft. The spring is located between the vertical plate and the handle.

[0014] A pathological tissue section staining treatment device includes a staining barrel. The above-mentioned storage rack is placed in the staining barrel. A protruding supporting portion is provided on the inner side wall of the staining barrel. The diameter of the cleaning plate is equal to the inner diameter of the staining barrel. The cleaning plate is located above the supporting portion. A drain port that can be opened and closed is provided at the lower end of the staining barrel.

[0015] The present invention is further configured to further include a waste liquid barrel. The staining barrel is detachably connected to the upper side of the waste liquid barrel.

[0016] The present invention is further configured such that the staining barrel is transparently provided.

[0017] By adopting the above technical solutions, the beneficial effects of the present invention are as follows: The pathological tissue section storage rack and staining treatment device provided by the present invention can complete the staining treatment of the sections only in one staining barrel. After the sections are treated with the first solution, the first solution is drained, and then the sections are cleaned to avoid cross-contamination between the solutions. After the cleaning solution is drained, the second solution is added for treatment. In this way, according to the staining scheme, various subsequent required staining solutions are added in sequence, and the above operations are repeated until all the staining steps are completed.

[0018] Meanwhile, a cleaning plate is provided on the section storage rack in this application. The cleaning solution can be guided by the cleaning plate to clean the sections, improving the quality and efficiency of cleaning.

[0019] In addition, the handle can drive the glass slide to deflect and slightly shake through the driving bar, thus improving the cleaning effect and the staining efficiency. Description of the Drawings

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] As follows for referenceFigures 1-8 Description of the present invention: A pathological tissue section staining treatment device includes a staining barrel 16. The staining barrel 16 is a cylindrical barrel structure with an upward opening. This upward opening design facilitates operation. Whether it is placing the pathological tissue section storage rack or adding or replacing the staining solution, it is relatively convenient.

[0031] The bottom of the staining barrel 16 is provided with a drain port 18 that can be opened and closed. The solution in the staining barrel 16 is discharged through the drain port 18. When switching the staining process, for example, after completing the staining with one solution, it is necessary to drain the used solution. At this time, the drain port 18 can play a role in draining the liquid in the barrel, preparing for the next operation, ensuring that different staining solutions do not mix with each other, avoiding cross - contamination, and ensuring the accuracy of the staining result.

[0032] A pathological tissue section storage rack used inside the staining barrel 16 includes a rack body 1. The rack body 1 is the basic structure for carrying the glass slides. A number of slots 2 are provided on the rack body 1. Each slot 2 provides stable support for the glass slide, preventing the glass slide from shifting or slipping during dynamic processes such as staining and cleaning, ensuring that the section is always in the correct processing position, and thus guaranteeing the consistency of the staining effect.

[0033] A horizontally arranged cleaning plate 3 is connected to the upper side of the rack body 1. The cleaning plate 3 is circular, and the diameter of the cleaning plate 3 is equal to the inner diameter of the staining barrel 16. This design enables the cleaning plate 3 to fit the inner cavity of the staining barrel 16 after being placed in the staining barrel 16.

[0034] Insertion openings 4 corresponding to the slots 2 are provided on the cleaning plate 3. The insertion openings 4 correspond to the slots 2 one by one. The glass slide is inserted into the slot 2 through the insertion opening 4.

[0035] A protruding supporting part 17 is provided on the inner side wall of the staining barrel 16. The supporting part 17 is located at the middle position in the up - down direction of the staining barrel 16, and the cleaning plate 3 is located above the supporting part 17.

[0036] When the cleaning plate 3 is placed in the staining barrel 16 together with the storage rack, the lower side surface of the cleaning plate 3 abuts against the supporting part 17 at the middle position on the inner side wall of the staining barrel 16. On the one hand, it ensures the stable placement of the storage rack in the barrel. On the other hand, there is a gap between the lower end of the rack body 1 and the bottom of the staining barrel 16, reserving space for liquid flow and discharge.

[0037] A water leakage groove 15 is provided on the side wall of the insertion opening 4, and a number of water leakage holes 6 are distributed on the cleaning plate 3.

[0038] In the cleaning process, cleaning solution is poured into the staining bucket 16. Due to the limited drainage speed of the water leakage groove 1 and the water leakage holes 6, the cleaning solution will temporarily accumulate in the staining bucket 16 above the cleaning plate 3. As the solution accumulates, a certain water pressure will be generated, prompting the solution to flow from the water leakage groove 1 towards the slide, comprehensively flushing the slide to remove the solution remaining from the previous staining process; at the same time, the solution flowing from the water leakage holes 6 and the water leakage groove 1 will flow towards the frame 1 to flush the frame 1 and remove the attached residual solution. In addition, the cleaning solution will also flow downward along the edge of the cleaning plate 3 and flow along the inner wall of the staining bucket 16 to comprehensively flush the bucket wall, ensuring the cleanliness of the entire internal environment of the staining bucket 16, providing a reliable basis for subsequent staining steps, effectively avoiding solution cross-contamination, improving the cleaning quality and efficiency, and ensuring the accuracy and reliability of the staining process.

[0039] In actual operation, using the pathological tissue section storage rack and staining treatment device of the present invention, a complex staining process can be completed only within a single staining bucket 16. According to the established staining plan, first add the first staining solution to process the section. After the processing is completed, open the drain port 18 to drain the solution, then pour in the cleaning solution for comprehensive cleaning. After the cleaning is completed, close the drain port 18 and then add the second staining solution, and so on in a cycle until all staining steps are completed, efficiently and accurately realizing the staining treatment of pathological tissue sections.

[0040] The frame 1 is a U-shaped structure with an upward opening. The two ends on the upper side of the frame 1 are fixedly connected to the cleaning plate 3, and this connection method constructs the overall structure of the storage rack. The fixed connection ensures that the frame 1 and the cleaning plate 3 always maintain a relatively stable positional relationship during use and will not become loose or separated due to frequent solution replacement, equipment movement, etc.

[0041] The slot 2 is arranged on the upper side of the middle part of the frame 1. The space of the frame 1 is fully utilized, enabling a reasonable number of slots 2 to be arranged within the limited U-shaped structure range.

[0042] A U-shaped handle 7 with a downward opening is connected to the upper side of the cleaning plate 3. This shape fits closely with the overall device layout and has strong practicability.

[0043] The two ends of the handle 7 are rotatably connected to the cleaning plate 3. The handle 7 includes two left and right side arms 71 and a connecting bar 72 in the middle. The lower ends of the two side arms 71 are respectively rotatably connected to the cleaning plate 3, enabling the handle 7 to swing left and right within a certain range with these two connection points as axes. The upper ends of the two side arms 71 are respectively rotatably connected to the two ends of the connecting bar 72.

[0044] It also includes a long driving bar 8. The two ends of the driving bar 8 are respectively movably connected to the two side arms 71. When the handle 7 swings left and right, it can drive the driving bar 8 to move left and right.

[0045] On the lower side of the driving bar 8, a plurality of driving arms 9 extending downward are provided at intervals along its length direction. The positions of these driving arms 9 are precisely corresponding to the placement height of the glass slide. The upper end of the glass slide inserted into the insertion opening 4 and the slot 2 is located between two adjacent driving arms 9. In this way, when the driving bar 8 moves left and right, the glass slide can be driven to sway left and right.

[0046] In the cleaning process, the operator holds the handle 7 and shakes it left and right. The swing of the handle 7 drives the driving bar 8 to move, and the driving arms 9 move accordingly, thereby causing the glass slide to sway left and right in the slot 2. This swaying effect greatly improves the cleaning efficiency because it breaks the limitation of the cleaning solution relying solely on its own flow for cleaning, enabling all surfaces of the glass slide to come into more sufficient contact with the cleaning solution, and thoroughly removing possible residual staining solutions, impurities, etc. During the staining process, by the same principle, the swaying of the glass slide enables the staining solution to penetrate more evenly around the tissue section, enhancing the uniformity and quality of the staining, ensuring that the pathological section can present accurate and clear cell morphology and pathological features, and providing a solid basis for subsequent diagnosis.

[0047] Connecting shafts 10 are respectively provided at both ends of the driving bar 8, and movable slots 11 connected to the connecting shafts 10 are provided on the side arms 71. The movable slots 11 are arranged in the up and down direction. When the side arms 71 of the handle 7 swing left and right, on the one hand, the connecting shafts 10 move left and right along with the driving bar 8, and on the other hand, they can smoothly move up and down in the movable slots 11.

[0048] The cross-section of the connecting shaft 10 is square, and the two side surfaces of the connecting shaft 10 are in contact with the two side walls in the width direction of the movable slot 11, thus preventing the connecting shaft 10 and the driving bar 8 from rotating.

[0049] The width of the insertion opening 4 is specially designed to be greater than the thickness of the glass slide. This detail directly determines the left and right swaying range of the glass slide. The relatively wide insertion opening 4 reserves space for the swaying of the glass slide during cleaning and staining while ensuring that the glass slide can be smoothly inserted into the slot 2. When the operator manipulates the driving bar 8 to make the glass slide sway through the handle 7, the glass slide can swing smoothly and freely within the left and right range defined by the insertion opening 4, neither being blocked due to too narrow a space, which would affect the cleaning and staining effects, nor getting out of control due to too large a space, resulting in problems such as collision and displacement, further optimizing the overall performance of the device and ensuring the efficient and accurate progress of pathological section processing work.

[0050] Another implementation structure of the handle 7: The handle 7 is a U-shaped structure with a downward opening. The handle 7 is an integral structure and cannot swing. The two ends on the lower side of the handle 7 are fixedly connected to the cleaning plate 3.

[0051] The distance from the middle of the handle 7 to the cleaning plate 3 is greater than the length of the slide, so there is enough space for the slide to be inserted into the insertion opening 4 on the upper side of the cleaning plate 3.

[0052] When the width of the insertion opening 4 is greater than the thickness of the slide, the first water leakage groove 5 can be not provided or can be provided, and can be selected according to needs.

[0053] When using a fixed structure and non-swingable handle 7, the insertion opening 4 is preferably arranged to be adapted to the slide, and at this time, the first water leakage groove 5 must be provided.

[0054] A plurality of second water leakage grooves 12 are provided along the circumference of the edge of the cleaning plate 3. When the cleaning solution accumulates on the cleaning plate 3, the liquid will naturally flow to the edge of the cleaning plate 3 by its own gravity. At this time, the second water leakage grooves 12 are like carefully designed drainage pipes, which can quickly capture these converging liquids and guide them to flow downward along the grooves to the inner wall of the staining barrel 16 to wash the inner wall of the staining barrel 16.

[0055] Vertical plates 13 corresponding to both sides of the handle 7 are provided on the cleaning plate 3. The vertical plates 13 are spaced from the corresponding side arms 71, which neither affects the normal swing of the handle 7 nor provides a stable support surface for the installation of subsequent components. Connection grooves 14 connected to the connecting shaft 10 are provided on the vertical plates 13, and a spring 15 is sleeved on the connecting shaft 10. The spring 15 is located between the vertical plate 13 and the handle 7.

[0056] When the device is in the initial state or non-operation period, the left and right springs 15 will apply an inward elastic force to the handle 7 to keep the handle 7 in a relatively stable vertical state. The maintenance of this vertical state has multiple meanings: in terms of operation convenience, when the operator is carrying, placing or preparing to operate the device daily, the vertically stable handle 7 is easier to grasp, conforms to the ergonomic principle, and reduces the operation difficulty and error rate; from the perspective of device protection, the stable handle 7 can reduce the potential damage risk to the internal components of the device such as the drive strip 8 and the slide slot caused by accidental shaking and collision; in terms of function realization, the left and right swing of the handle 7 needs to overcome the elastic force of the spring 15, which means that when the operator is performing cleaning or staining related operations and needs to shake the slide, a certain and conscious external force must be applied to avoid unnecessary shaking of the slide caused by the overly sensitive or random shaking of the handle 7, ensuring the accuracy and controllability of the shaking operation, so that the slide shakes at the expected amplitude and frequency when needed, thereby optimizing the quality and efficiency of cleaning and staining.

[0057] The movable slot 11 and the connecting slot 14 are both arranged in the up and down direction, and the upper side extends to be close to the connecting bar 72. This enables the driving bar 8 to adjust its position in the up and down direction. When it is necessary to insert a slide, the driving bar 8 can move upward. After the slide is inserted, the driving bar 8 moves downward to be close to the slide, and the upper end of the slide is located between two adjacent driving arms 9. The spring 15 is located between the vertical plate 13 and the side arm 71 and is in a compressed state, forming a pre-tightening force, which can position the driving bar 8. The sides of the vertical plate 13 and the side arm 71 in contact with the spring 15 can be roughened to increase the friction between the spring 15 and the vertical plate 13 and the side arm 71, and reduce the accidental sliding of the spring 15 in the up and down direction.

[0058] The angle range of the left and right swing of the side arm 71 is between 3 and 6 degrees, so as to form a slight shaking of the slide.

[0059] It also includes a waste liquid bucket 19, and the staining bucket 16 is detachably connected to the upper side of the waste liquid bucket 19. The detachable connection facilitates daily cleaning and maintenance. Whether the staining bucket 16 needs to be deeply cleaned after being contaminated with the staining solution, or the waste liquid bucket 19 needs to be emptied after accumulating a certain amount of waste liquid, the operator can easily separate the two, simplify the operation process, and reduce the labor intensity.

[0060] The liquid discharged from the staining bucket 16 can accurately enter the waste liquid bucket 19 and be collected. This effectively prevents the waste liquid from flowing randomly and causing pollution to the laboratory table or floor, not only maintaining the cleanliness and hygiene of the laboratory, but also meeting the requirements of environmental protection specifications and avoiding potential hazards to the environment caused by the waste liquid. In actual operation, when a staining process or a cleaning step is completed, the drain port 18 of the staining bucket 16 is opened, and the waste liquid naturally flows into the lower waste liquid bucket 19 under the action of gravity. The whole process is smooth and reliable, laying a good foundation for subsequent continuous staining treatment steps.

[0061] The staining bucket 16 is made of transparent material. During daily operation, the operator can directly observe the situation inside the staining bucket 16 through the transparent barrel wall and grasp the staining process in real time. For example, when adding the staining solution, it can be visually confirmed whether the solution is evenly distributed and whether there are precipitates or impurities mixed in; during the cleaning process, it can be clearly seen the flow state of the cleaning solution and whether the residual staining solution is completely removed. This visualization feature greatly improves the accuracy and convenience of the operation, reduces operation errors caused by information asymmetry, and helps to improve the quality of pathological section staining.

[0062] Considering that some special staining solutions may be sensitive to light and need to be stored in the dark to ensure that the staining effect is not affected, the staining bucket 16 can also be treated to be light-proof.

[0063] A valve can be installed at the liquid discharge port 18, and the opening and closing of the valve are controlled by the valve stem of the valve, so as to control the opening and closing of the liquid discharge port 18. During the dyeing process, when the treatment of a certain dyeing solution is completed, the operator only needs to operate the valve stem to open the valve, and the dyeing solution will flow into the waste liquid bucket 19 through the liquid discharge port 18. After the discharge is completed, operate the valve stem to close the valve again, and subsequent cleaning or adding new dyeing solution and other steps can be carried out. The valve stem of the valve is not shown in the figure.

[0064] The working principle of this pathological tissue section dyeing treatment device is as follows: First is the section loading link. The glass slide is inserted into the slot 2 of the frame body 1 through the insertion port 4 on the cleaning plate 3.

[0065] Then it enters the dyeing process. The dyeing bucket 16 is a cylindrical structure with an upward opening. The storage rack containing the sections is placed into the dyeing bucket 16. Add the first dyeing solution into the dyeing bucket 16, and the solution submerges the glass slide to carry out the dyeing treatment on the pathological section. The dyeing time depends on different pathological requirements and dyeing schemes.

[0066] After the first dyeing is completed, open the liquid discharge port 18 by operating the valve installed on the liquid discharge port 18 (such as rotating the valve stem to control the opening and closing of the valve core), and discharge the dyeing solution into the waste liquid bucket 19. After emptying the solution, pour in the cleaning solution to start the cleaning step.

[0067] During cleaning, the cleaning solution will accumulate in the dyeing bucket 16. Since the cleaning plate 3 is provided with a water leakage groove 5 corresponding to the insertion port 4 and a number of distributed water leakage holes 6, the solution will not be discharged immediately, but will be temporarily accumulated in the dyeing bucket 16 above the cleaning plate 3 and gradually flow downward through the water leakage groove 5 and the water leakage holes 6. During this flowing process, on the one hand, the solution flows downward along the edge of the cleaning plate 3 and flows along the inner wall of the dyeing bucket 16 to wash the bucket wall comprehensively; on the other hand, the solution flowing downward through the water leakage groove 5 will wash the glass slide comprehensively, and the solution flowing downward through the water leakage groove 5 and the water leakage holes 6 will wash the frame body 1 comprehensively, realizing the effective cleaning of the entire device interior and avoiding the residue of the dyeing solution from the previous process. Moreover, when the handle 7 is designed to be swingable left and right, the left and right swing of the handle 7 drives the driving bar 8 to move, and the driving arms 9 arranged at intervals on the lower side of the driving bar 8 can make the glass slide swing left and right, further improving the cleaning effect. The liquid discharge port 18 is in the open state during cleaning, and after the cleaning is completed, the liquid discharge port 18 is closed, pour in the next dyeing solution, and repeat the above dyeing and cleaning steps until all dyeing processes are completed.

[0068] During cleaning, the liquid discharge port 18 can also be in the closed state; or the liquid discharge port 18 is first opened and then closed. After closing, the cleaning liquid in the dyeing bucket 16 can form an immersion cleaning for the storage rack and the like.

[0069] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
