Description

Technical Field

[0001] This invention relates to the field of medical testing technology, and more particularly to a pathological slide washing device. Background Technology

[0002] Pathological examination is the gold standard for disease diagnosis. The accuracy of pathological examination determines the correctness of subsequent treatment and management by clinicians; incorrect diagnoses can even endanger a patient's life. Medical accidents caused by contamination of pathological slides are also frequent in pathology departments. During tissue slide preparation, many tissue debris often remain on the surface of the rinsing liquid, causing contamination between different tissue slides during retrieval, affecting the accuracy of pathological diagnosis and leading to serious consequences for patients. Currently, pathology technicians typically use absorbent paper to manually clean the debris from the liquid surface. This method is not only wasteful of paper but also very tedious, and debris tends to accumulate along the edge of the trough. The water surface is also prone to overflowing under the movement of the absorbent paper, contaminating the work surface.

[0003] In existing technologies, there are mechanical scraper-type and suction-type, which are improvements on the scraper-type. The scraper-type uses a scraper to sweep across the water surface, removing debris through mechanical force. The disadvantages are that if the scraper is too high, it will not reach the water surface, and if it is too low, it will easily hit the edge of the water tank. Also, water needs to be added frequently after scraping, and debris adhering to the scraper needs to be cleaned frequently. The suction-type is based on the scraper-type, using a tongue plate that acts as an adsorbent to sweep across the water surface, relying on the adsorption of the tongue plate to absorb debris from the water surface. The disadvantages of the suction-type are that its adsorption effect is questionable, debris tends to accumulate on the edge of the water tank, and the tongue plate needs to be replaced frequently. Also, with each sweep across the water surface, some water is scraped away, and water needs to be added frequently after the water level drops.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0007] This invention discloses a pathological slide washing device, including a slide washing box, a support plate, and a filter screen.

[0008] In any of the above embodiments, preferably, the floating plate cylinder mechanism includes an upper support plate, a sleeve, and a lower support plate. A snap-fit ​​ring is fixedly connected to the outer wall of the bottom end of the sleeve. An annular snap-fit ​​groove corresponding to the snap-fit ​​ring is opened at the top end of the lower support plate. The sleeve is rotatably snapped onto the lower support plate through the snap-fit ​​ring. The top end of the sleeve is fixedly connected to the bottom end of the upper support plate. Four connecting rods are evenly fixedly connected to the bottom end of the lower support plate. The bottom ends of the four connecting rods are movably inserted into the extrusion plate. The bottom ends of the connecting rods extend to the bottom end of the extrusion plate and are fixedly connected to the limiting plate. The bottom end of the upper support plate is fixedly connected to the top end of the floating plate cylinder. The extrusion plate is slidably connected to the inner wall of the floating plate cylinder.

[0009] In any of the above embodiments, it is preferred that a second cylinder is fixedly installed at the center of the top end of the lower support plate, the output end of the second cylinder passes through the lower support plate and is fixedly connected to the top end of the extrusion plate, a protective cylinder is fixedly connected to the top end of the lower support plate, the protective cylinder is sleeved outside the second cylinder, and a first gear is fixedly sleeved on the outer wall of the protective cylinder.

[0010] In any of the above embodiments, it is preferred that a motor is fixedly installed at the top of the upper support plate, the output shaft of the motor passes through the upper support plate and extends into the protective cylinder, and a second gear is fixedly connected to the output shaft of the motor, the second gear meshing with the first gear.

[0011] In any of the above embodiments, it is preferred that four conical sleeves are uniformly and fixedly connected to the top of the extrusion plate, and the four conical sleeves are respectively movably sleeved on the four connecting rods.

[0012] In any of the above embodiments, it is preferred that both the upper and lower ends of the float tube are open, and the float tube is provided with a tube door.

[0013] In any of the above embodiments, it is preferred that the floating plate cylinder, the extrusion plate, the lower support plate, the sleeve, and the protective cylinder are all provided with multiple through holes.

[0014] In any of the above solutions, it is preferred that a camera is fixedly installed at the top inside the floating film box, a control module is provided at the front end of the floating film box, and a liquid level sensor is also installed inside the floating film box.

[0015] In any of the above embodiments, it is preferred that filter screen frames are provided at both ends of the filter screen to support the filter screen, and the filter screen, cleaning tank, impurity removal port and return port are on the same horizontal plane.

[0016] In any of the above embodiments, it is preferred that the bottom of the diversion pool is inclined, and the lower end of the bottom of the diversion pool is connected to the floating plate box and located below the return port.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. By placing pathological slides into the bleaching cylinder mechanism, the slides are immersed in bleaching tablets in the bleaching box through the bleaching cylinder mechanism. Impurities floating on the surface of the bleaching tablets are pushed into the cleaning tank through a filter screen. After bleaching, the pathological slides can be squeezed out of the bleaching tablets through the bleaching cylinder mechanism, reducing weight and making them easier to handle. The bleaching tablets remaining on the bleaching cylinder mechanism are collected into the bleaching box for reuse using a drainage tank. The whole process can reduce the waste of bleaching tablets, speed up the bleaching time of pathological slides, improve efficiency, and reduce manual labor through intelligent operation.

[0019] 2. A slide tube mechanism containing pathological slides is brought into the slide tube box by a first slider and a first slide rail. A first cylinder drives the slide tube mechanism to descend and immerse it in the bleaching tablets. A motor is fixedly installed on the upper support plate, and a second gear is fixedly connected to the output shaft of the motor. A protective cylinder is installed at the top of the lower support plate, and a first gear is fixedly sleeved on the outer wall of the protective cylinder. The motor drives the second gear to rotate, which in turn drives the first gear to rotate, thereby driving the lower support plate and the slide tube to rotate. This causes the pathological slides to sway in the slide tube, ensuring full contact between the pathological slides and the bleaching tablets, shortening the slide bleaching time and improving efficiency. A second cylinder is installed in the protective cylinder, and the output end of the second cylinder is fixedly connected to a squeezing plate. After the slide bleaching is completed, the second cylinder drives the squeezing plate to move upward, squeezing the pathological slides in the slide tube and expelling the bleaching tablets from the pathological slides. This facilitates the handling of the pathological slides and avoids the waste of bleaching tablets.

[0020] 3. By opening a bleaching port on one side of the bleaching box and connecting it to a cleaning pool, and installing second slide rails on the inner walls at both ends of the bleaching box, a filter screen is slidably connected between the two second slide rails. The filter screen slides on the surface of the bleaching tablets, thereby pushing impurities in the bleaching process through the bleaching port into the cleaning pool, making it easier for operators to clean impurities and ensuring the cleanliness of the bleaching tablets.

[0021] 4. By installing a filter plate on the other side of the bleaching plate box and a diversion pool below the filter plate, one end of the diversion pool is connected to the return port on the bleaching plate box. When the first slider drives the bleaching plate cylinder mechanism to slide above the filter plate, the first cylinder drives the bleaching plate cylinder mechanism to descend above the filter plate. The bleaching plate pieces remaining on the bleaching plate cylinder mechanism fall into the diversion pool through the filter plate. The diversion pool is inclined, so that the bleaching plate pieces falling into the diversion pool flow back into the bleaching plate box through the return port, reducing the consumption of bleaching plate pieces.

[0036] Example

[0037] like Figure 1, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 ,and Figure 7 As shown, a pathological slide rinsing device includes a slide rinsing box 1, a support plate 3, and a filter screen 18. The slide rinsing box 1 has an observation port 11 at its front end, allowing observation of the interior. A top plate 4 is fixedly connected to one side of the slide rinsing box 1. A first slide rail 9 is fixedly installed at the top of the interior of the slide rinsing box 1, with one end extending to be fixedly connected to the top plate 4. The first slide rail 9 is an electric slide rail. An inlet / outlet is provided on the side wall of the slide rinsing box 1 near the top plate 4, facilitating the entry and exit of the slide rinsing cylinder mechanism 5. A first slider 10 is slidably connected to the first slide rail 9, through which the first slider 10... The slide container mechanism 5 moves to the slide container 1 or filter plate 2 for convenient collection of pathological slides. The bottom end of the first slider 10 is fixedly connected to the first cylinder 12, and the output end of the first cylinder 12 is fixedly connected to the top end of the slide container mechanism 5. The first cylinder 12 drives the slide container mechanism 5 to move up or down, immersing the slide container mechanism 5 in bleaching tablets. The slide container 1 has a return port on the side near the top plate 4. The return port is used to return the bleaching tablets that drip into the drainage pool 6 back to the slide container 1 for reuse, avoiding waste of bleaching tablets. A filter plate 2 is fixedly connected between the support plate 3 and the slide container 1. The filter plate 2 can catch the bleaching tube mechanism 5 after soaking and moving it outside the bleaching box 1, facilitating the loading of pathological sections after bleaching. Simultaneously, it does not obstruct the flow of bleaching tablets remaining on the bleaching tube mechanism 5 into the drainage pool 6. The support plate 3 has a drainage pool 6 located directly below the filter plate 2. The drainage pool 6 catches the bleaching tablets remaining on the bleaching tube mechanism 5 and returns them to the bleaching box 1 for reuse, reducing the consumption of bleaching tablets. One end of the drainage pool 6 is open and fixedly connected to the bleaching box 1, facilitating the return of bleaching tablets. A second slide rail 16 is fixedly connected to the inner walls of both the front and rear ends of the bleaching box 1. The second slide rail 16 is an electric slide rail, and a second slider 17 is slidably connected to the second slide rail 16. The two ends of the filter screen 18 are fixedly connected to the second sliders 17 on the two second slide rails 16 respectively. The filter screen 18 slides on the surface of the bleaching tablets using the second sliders 17, pushing the impurities floating on the surface of the bleaching tablets into the cleaning tank 7 for centralized cleaning, which can ensure the cleanliness of the bleaching tablets. The bleaching tablet box 1 has a cleaning port 19 on the side away from the return port, which makes it convenient for the filter screen 18 to push the impurities into the cleaning tank 7. The cleaning tank 7 is fixedly connected to the side of the bleaching tablet box 1 near the cleaning port 19, which is used to collect the impurities floating on the surface of the bleaching tablets, making it convenient for operators to clean.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The floating plate cylinder mechanism 5 includes an upper support plate 501, a sleeve 502, and a lower support plate 505. A snap-fit ​​ring 503 is fixedly connected to the outer wall of the bottom end of the sleeve 502. An annular snap-fit ​​groove 504 corresponding to the snap-fit ​​ring 503 is opened at the top end of the lower support plate 505. The sleeve 502 is rotatably snapped onto the lower support plate 505 through the snap-fit ​​ring 503. By setting the sleeve 502 to be rotatably snapped onto the lower support plate 505 through the snap-fit ​​ring 503, the sleeve 502 can be rotated on the lower support plate 505 while being connected to it. The top end of the sleeve 502 is fixedly connected to the bottom end of the upper support plate 501. Four connecting rods 506 are evenly fixedly connected to the bottom end of the lower support plate 505. The bottom ends of the four connecting rods 506 are movably inserted into the extrusion plate 513. By setting the connecting rods 506, the extrusion plate 513 can move smoothly during the up and down movement. The bottom ends of the connecting rods 506 extend to the bottom end of the extrusion plate 513 and are fixedly connected to the limiting plate 507. By setting the limiting plate 507, the extrusion plate 513 can be prevented from detaching from the connecting rods 506 and the height of the extrusion plate 513 downward movement can be limited. The bottom end of the upper support plate 501 is fixedly connected to the top end of the bleaching tube 508. The extrusion plate 513 is slidably connected to the inner wall of the bleaching tube 508. The extrusion plate 513 squeezes the pathological slide after bleaching, squeezing out the bleaching tablets in the pathological slide, making it convenient to pick up the pathological slide.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a second cylinder 13 is fixedly installed at the center of the top of the lower support plate 505. The output end of the second cylinder 13 passes through the lower support plate 505 and is fixedly connected to the top of the extrusion plate 513. After the bleaching is completed, the second cylinder 13 drives the extrusion plate 513 to move upward, extruding the pathological slides in the bleaching cylinder 508 and squeezing out the bleaching tablets from the pathological slides. This facilitates the removal of the pathological slides and avoids the waste of bleaching tablets. A protective cylinder 512 is fixedly connected to the top of the lower support plate 505. The protective cylinder 512 is sleeved outside the second cylinder 13. The protective cylinder 512 is used to connect the first gear 511 outside the second cylinder 13 without affecting the use of the second cylinder 13. The first gear 511 is fixedly sleeved on the outer wall of the protective cylinder 512. The first gear 511 meshes with the second gear 14 and can rotate when the motor 15 is started, so as to rotate the bleaching cylinder mechanism 5.

[0040] like Figure 3 and Figure 4As shown, a motor 15 is fixedly installed at the top of the upper support plate 501. The output shaft of the motor 15 passes through the upper support plate 501 and extends into the protective cylinder 512. A second gear 14 is fixedly connected to the output shaft of the motor 15. The second gear 14 meshes with the first gear 511. The motor 15 drives the second gear 14 to rotate, which in turn drives the first gear 511 to rotate, thereby driving the lower support plate 505 and the slide tube 508 to rotate. This causes the pathological slides to sway in the slide tube 508, ensuring that the pathological slides and the slide tube are in full contact, shortening the slide rinsing time and improving efficiency.

[0041] like Figure 3 and Figure 4 As shown, four conical sleeves 510 are evenly fixedly connected to the top of the extrusion plate 513. The four conical sleeves 510 are respectively movably sleeved on the four connecting rods 506. By setting the conical sleeves 510, the pathological slides can be prevented from getting stuck at the connection between the connecting rod and the extrusion plate, thus affecting the upward movement of the extrusion plate.

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the upper and lower ends of the slide tube 508 are open to facilitate the movement of the compression plate 513. The slide tube 508 is provided with a tube door 509, which facilitates the loading and unloading of pathological slides into the slide tube 508.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bleaching tube 508, the squeezing plate 513, the lower support plate 505, the sleeve 502 and the protective tube 512 are all provided with multiple through holes, which facilitates the entry of bleaching tablets into the bleaching tube 508 to contact the pathological slides, and is beneficial for the bleaching of pathological slides.

[0044] like Figure 1 and Figure 2As shown, a camera 8 is fixedly installed at the top of the inside of the bleaching tablet box 1. A control module 20, which is a PLC controller, is set at the front end of the bleaching tablet box 1. A liquid level sensor is also installed inside the bleaching tablet box 1. When the camera 8 detects impurities floating on the surface of the bleaching tablets after bleaching, it transmits a signal to the control module 20. The control module 20 controls the second slider 17 on the second slide rail 16 to slide, so that the filter screen 18 slides and pushes the impurities floating on the surface of the bleaching tablets to the cleaning pool 7 for cleaning. At the same time, the liquid level sensor monitors the liquid level of the bleaching tablets at all times and transmits the data to the control module 20. The control module 20 compares the data with the pre-stored normal liquid level of the bleaching tablets. If the liquid level is lower than the normal data, the bleaching device stops running until the operator adds bleaching tablets until the liquid level returns to normal. Then, the control module 20 controls the device to continue running.

[0045] like Figure 1 , Figure 5 and Figure 7 As shown, filter screen 18 is provided with filter screen frames at both ends for supporting filter screen 18, which facilitates connection of the second slider 17. The filter screen 18, cleaning tank 7, impurity removal port 19 and return port are on the same horizontal plane. The cleaning tank 7 and impurity removal port 19 are on the same horizontal plane, which makes it convenient for the filter screen 18 to push impurities floating on the surface of the bleaching tablet into the cleaning tank 7.

[0046] like Figure 1 , Figure 2 and Figure 6 As shown, the bottom of the diversion pool 6 is inclined, which is used to allow the bleaching tablets that fall into the diversion pool 6 to automatically flow back to the bleaching tablet box 1 through the return port, thereby reducing the consumption of bleaching tablets. The lower end of the bottom of the diversion pool 6 is connected to the bleaching tablet box 1 and is located below the return port, which facilitates the return of bleaching tablets.

[0047] Working principle: By opening the cylinder door 509, pathological slides are placed in the bleaching cylinder 508. The control module 20 controls the first slider 10 to slide in the first slide rail 9, driving the bleaching cylinder mechanism 5 to move into the bleaching box 1. The first cylinder 12 drives the bleaching cylinder mechanism 5 to move down into the bleaching tablet, so that the pathological slides in the bleaching cylinder 508 are bleached. The control module 20 controls the motor 15 to start, causing the second gear 14 to rotate. The second gear 14 meshes with the first gear 511, thereby causing the first gear 511 and the protective cylinder 512 in the first gear 511 to rotate. Since the protective cylinder 512 is fixedly connected to the lower support plate 505, the lower support plate 505 and the bleaching cylinder 508 rotate together. This rotation increases the fluidity of the bleaching tablet, allowing it to fully contact the pathological slides and improving the bleaching efficiency. After bleaching, the first cylinder 12 drives the bleaching cylinder mechanism 5 to rise, and then the second cylinder 13 starts, driving the extrusion plate 513 to move upward and extrude the pathological slides. After the bleaching tablets are squeezed out of the bleaching tablets, the first slider 10 drives the bleaching tablet cylinder mechanism 5 to move onto the filter plate 2. The bleaching tablets remaining on the bleaching tablet cylinder mechanism 5 enter the inclined drainage pool 6 through the filter plate 2 and flow back to the bleaching tablet box 1 through the return port for continued use, reducing the consumption of bleaching tablets. The liquid level sensor monitors the liquid level of the bleaching tablets at all times and transmits the data to the control module 20. The control module 20 compares the data with the pre-stored normal liquid level of the bleaching tablets. If the liquid level is lower than the normal data, the bleaching device stops running until the operator adds bleaching tablets to restore the liquid level. Then, the control module 20 controls the device to continue running. The camera 8 detects whether there are impurities floating on the liquid surface of the bleaching tablets and transmits the data to the control module 20. If impurities are detected, the control module 20 controls the second slider 17 to drive the filter screen 18 to slide on the liquid surface of the bleaching tablets. The filter screen 18 pushes the impurities floating on the liquid surface to the cleaning pool 7 for cleaning. After cleaning, the next batch of bleaching tablets can be processed.

[0048] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
