Description

Technical Field

[0001] The invention relates to the technical field of pathological detection, in particular to a pathological section staining device. Background Art

[0002] Pathological section staining is an important technique in pathological examination. It helps pathologists diagnose diseases by staining tissue or cell sections to make cell structures and components that were difficult to distinguish under a microscope clearly visible. The process of pathological section staining usually includes the steps of section making, staining, sealing and observation. First, the biopsy tissue or surgically removed specimen is fixed, dehydrated, embedded and made into sections. Then, the appropriate staining method is selected for staining according to the diagnostic needs. Finally, the stained sections are sealed and observed for accurate diagnosis under a microscope.

[0003] In order to improve the dyeing quality during the dyeing process, the dyeing time requirement is high. The current timer is generally used for timing. At the same time, the dyeing agent will be recycled and reused for cost considerations. However, the number of times the dyeing agent is recycled will affect the dyeing effect. Normally, the more times the dyeing agent is recycled, the longer the dyeing time will be. However, in actual use, it is difficult for operators to know the actual impact of the number of recycling times on the dyeing time. Therefore, during the dyeing process, the slices are often taken out for observation after the normal dyeing time is reached, and then the dyeing is continued according to the dyeing situation after observation, which is not convenient during operation.

[0004] To this end, we propose a pathological section staining device. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] See also Figures 1 to 10The present invention provides a technical solution: a pathological section staining device, comprising: a box body 1, a lifting mechanism 2 that can be automatically locked is installed on the top of the box body 1, and a staining rack can be installed at the bottom of the lifting mechanism 2, so that the lifting mechanism 2 can synchronously drive the staining rack to move up and down when it is in motion, and at the same time, a staining container 3 is fixedly installed at the front end of the box body 1, and the staining container 3 stores a stain. When staining, the staining rack can be installed at the bottom of the lifting mechanism 2, and then the lifting mechanism 2 is started, and the lifting of the lifting mechanism 2 drives the staining rack to be immersed in the staining container 3 for staining.

[0041] Specifically, in this embodiment, the lifting mechanism 2 includes a support rod 8 fixed on the top of the box body 1, a rotating rod 9 is rotatably installed on the top of the support rod 8, an adjusting arm 10 and a force storage member 11 are fixedly installed on the outer side of the rotating rod 9, and the force storage member 11 stores force when the lifting mechanism 2 is extended, a first connecting rod 12 is rotatably installed on the end of the adjusting arm 10, a second connecting rod 13 is rotatably installed on the bottom of the first connecting rod 12, and the second connecting rod 13 is slidably installed at the front end of the box body 1, and the dyeing rack is plugged into the bottom of the second connecting rod 13.

[0042] Therefore, when the adjusting arm 10 is rotated, the adjusting arm 10 is rotated on the top of the supporting rod 8 through the rotating rod 9. At the same time, the first connecting rod 12 of the adjusting arm 10 drives the second connecting rod 13 to slide at the front end of the box body 1. The second connecting rod 13 drives the dyeing rack to move up and down when sliding. When the adjusting arm 10 rotates, it will synchronously drive the force storage member 11 to store force. However, since the lifting mechanism 2 can be automatically locked, that is, when the adjusting arm 10 is rotated to a certain angle, although the force storage member 11 will generate elastic force, the adjusting arm 10 will still stay in the adjusted position due to the locking effect.

[0043] Secondly, a connecting member 14 is installed at the end of the rotating rod 9, and a locking member 15 is installed at the output end of the connecting member 14. The locking member 15 locks the lifting stroke of the lifting mechanism 2. Specifically, the connecting member 14 first includes a first pulley 18 fixed to the end of the rotating rod 9, and a second pulley 19 is installed on the side of the locking member 15. A transmission belt 20 is installed between the first pulley 18 and the second pulley 19. Therefore, when the rotating rod 9 rotates, the first pulley 18 will be driven to rotate synchronously. When the first pulley 18 rotates, the second pulley 19 is driven to rotate synchronously through the transmission belt 20.

[0044] The locking member 15 is installed at the bottom of the box body 1, and the locking member 15 is composed of a ratchet 21 and a first pawl 22, wherein the ratchet 21 is rotatably installed at the bottom of the box body 1, and the first pawl 22 is installed on the top of the ratchet 21. The ratchet 21 realizes unidirectional rotation of the ratchet 21 through the action of the first pawl 22, and the second pulley 19 is coaxially connected with the ratchet 21. Therefore, when the adjusting arm 10 is adjusted, the rotating rod 9 rotates synchronously and accumulates force through the force storage member 11. At the same time, the rotation of the rotating rod 9 will also drive the ratchet 21 to rotate through the connecting member 14. When the adjusting arm 10 is pressed, the force storage member 11 accumulates force. At this time, the first pawl 22 will not be restricted by the ratchet 21, so the adjusting arm 10 can rotate normally, and the force storage member 11 will have a tendency to release after accumulating force, that is, drive the rotating rod 9 to reverse, but at this time the first pawl 22 will be restricted by the ratchet 21, so that the ratchet 21 cannot reverse, that is, the adjusting arm 10 can maintain the adjusted position after adjustment.

[0045] In this embodiment, the force storage member 11 is composed of a coil spring 17 and a fixed box 16, wherein the fixed box 16 is fixed to the top of the box body 1, and the coil spring 17 is installed inside the fixed box 16, and the inner side of the coil spring 17 is fixed to the outer side of the rotating rod 9. Therefore, when the rotating rod 9 rotates, the coil spring 17 will be synchronously driven to store force, so that the coil spring 17 generates elastic force.

[0046] Since the locking member 15 locks the adjusting arm 10 after the force is stored, when the locking member 15 is unlocked, the elastic force of the coil spring 17 in the force storage member 11 is released, and the rotating rod 9 will reverse, that is, drive the adjusting arm 10 to return to the initial position, thereby driving the staining frame to leave the staining container 3. Therefore, a trigger mechanism 5 is installed at the bottom of the box body 1, and the trigger mechanism 5 can unlock the locking member 15, and the time from when the trigger mechanism 5 starts to act to when the locking member 15 is unlocked is the staining time of the slice.

[0047] Specifically, the trigger mechanism 5 includes a friction member 25 and a trigger rod 26, and the friction member 25 includes a movable friction block 27 and a fixed friction block 28. In the present embodiment, three fixed friction blocks 28 are provided, and one movable friction block 27 is provided, and they are equidistantly distributed on the outside of the trigger rod 26. The trigger rod 26 is slidably mounted on the bottom of the box body 1, and the bottom is aligned with the first pawl 22. When the trigger rod 26 is released, the trigger rod 26 needs to overcome the friction between the movable friction block 27 and the fixed friction block 28 and fall down. In the process of falling, it gradually approaches the first pawl 22. When the bottom of the trigger rod 26 contacts the first pawl 22, the first pawl 22 is separated from the ratchet 21. At this time, the locking member 15 can be unlocked, and the adjustment arm 10 also returns to its initial state.

[0048] A first spring 29 is also installed on one side of the movable friction block 27, and a telescopic sleeve 30 is fixedly installed on the outer side of the first spring 29. The telescopic sleeve 30 is slidably installed on the outer side of the movable friction block 27. Therefore, when the telescopic sleeve 30 is pushed, the telescopic sleeve 30 slides on the outer side of the movable friction block 27, and at the same time, the first spring 29 is compressed and generates elastic force. When the first spring 29 generates elastic force, it acts on the movable friction block 27, so that the pressure between the movable friction block 27 and the trigger rod 26 increases, thereby increasing the resistance of the trigger rod 26 when it falls, and prolonging the contact time between the trigger rod 26 and the first pawl 22.

[0049] A recovery mechanism 6 is installed inside the box body 1, and the recovery mechanism 6 can recover the dye in the dyeing container 3. Specifically, a mounting plate 31 is installed inside the box body 1, that is, a slide bar 35 is slidably installed on the side of the mounting plate 31, and the slide bar 35 is fixed inside the box body 1. A second spring 36 is sleeved on the outer side of the slide bar 35, so that the mounting plate 31 can slide up and down on the slide bar 35, and the second spring 36 is extended and retracted during the up and down sliding process. A storage tank 32 is fixedly installed on the top of the mounting plate 31, and an input pipe 34 and an output pipe 33 are installed between the storage tank 32 and the dyeing container 3.

[0050] Through the above technical solution, when it is necessary to recover the dye in the dyeing container 3 into the storage tank 32, press the mounting plate 31 downward so that the height of the storage tank 32 on the mounting plate 31 is lower than the dyeing container 3. At this time, the dye in the dyeing container 3 will enter the storage tank 32 through the input pipe 34 under the action of gravity. When it is necessary to transfer the dye solvent in the storage tank 32 to the dyeing container 3, just pull the mounting plate 31 upward to adjust the height of the storage tank 32 to be higher than the dyeing container 3. At this time, the dye in the storage tank 32 will enter the dyeing container 3 through the output pipe 33.

[0051] When the dye is recovered, the mounting plate 31 needs to move downward. When the mounting plate 31 moves downward, it will drive the compensation mechanism 7, and the compensation mechanism 7 will gradually increase the friction between the movable friction block 27 and the trigger rod 26, thereby extending the time for the trigger rod 26 to trigger the first pawl 22, that is, the dyeing time.

[0052] Specifically, first, a second pawl 37 is rotatably installed on the side of the mounting plate 31, a third spring 38 is fixedly installed between the second pawl 37 and the mounting plate 31, a ratchet plate 39 is installed on the outer side of the second pawl 37, a fixing frame 40 is slidably installed on the outer side of the ratchet plate 39, the fixing frame 40 is fixed to the bottom of the box body 1, a fourth spring 41 is fixedly installed on the bottom of the ratchet plate 39 and the bottom of the fixing frame 40, a rack 42 is fixedly installed on the bottom of the ratchet plate 39, a gear 43 is meshed on one side of the rack 42, a screw 44 is fixedly installed on the end of the gear 43, a threaded sleeve 45 is threadedly connected to the outer side of the screw 44, the threaded sleeve 45 is slidably installed on the bottom of the box body 1, a connecting rod 46 is fixedly installed on the end of the threaded sleeve 45, and the other end of the connecting rod 46 is fixed to the outside of the telescopic sleeve 30.

[0053] When the mounting plate 31 moves upward, the second pawl 37 will not engage with the ratchet plate 39, and the mounting plate 31 can be reset. At the same time, the ratchet plate 39 is also reset under the action of the third spring 38.

[0054] Therefore, in summary, before staining, the staining rack needs to be installed at the bottom of the second connecting rod 13, and then the stain in the storage tank 32 is transported to the staining container 3 through the recovery mechanism 6. The staining time is determined according to different staining methods. For example, in the HE staining process, it generally takes two minutes to stain the slices with hematoxylin, while it only takes about twenty seconds to stain with eosin. After determining the staining time, the adjusting arm 10 is rotated to move the staining rack to the inside of the staining container 3 to prepare for staining. Secondly, the distance between the trigger rod 26 and the first ratchet 22 is determined according to the staining time. The longer the staining time, the longer the distance between the two. The trigger rod 26 is determined to be the trigger rod 26. After the distance between the rod 26 and the first pawl 22 is reduced, the trigger rod 26 will overcome the friction force and gradually descend. When it descends to contact with the first pawl 22, the locking piece 15 is unlocked, and the adjusting arm 10 returns to its original state under the action of the force storage piece 11, and the dyeing is completed. The dye is recovered after dyeing, and the compensation mechanism 7 is driven to operate during the recovery process. The compensation mechanism 7 increases the resistance when the trigger rod 26 descends. When the resistance is greater, it means that the number of recovery times is more, and the dyeing time is further extended. Therefore, the dyeing time can be adaptively changed according to the number of dye recovery times, while ensuring the dyeing effect, reducing the need for observation in the middle, and is more convenient when used.

[0055] It should be added that in order to more conveniently and intuitively adjust the distance between the bottom of the trigger rod 26 and the first pawl 22 according to the known dyeing time, a marking mechanism 4 is installed on the top of the box body 1. The marking mechanism 4 includes a pointer 23 fixed on the outer wall of the rotating rod 9 and an indicator disk 24 fixed on the top of the box body 1. Therefore, when the rotating rod 9 rotates, the pointer 23 will be driven to rotate synchronously. When the pointer 23 rotates, the scale is displayed on the indicator disk 24. The larger the scale value, the larger the distance between the trigger rod 26 and the first pawl 22. Similarly, the scale line can be sprayed on one side of the trigger rod 26 to adjust the initial position of the trigger rod 26 according to the dyeing time.

[0056] In order to facilitate the adjustment of the storage tank 32 and the trigger rod 26, a first through hole 48 and a second through hole 49 are opened on the side of the box body 1, and an adjusting rod 47 is fixedly installed on the side of the storage tank 32. The adjusting rod 47 is slidably installed in the first through hole 48, and the top of the trigger rod 26 is slidably installed in the second through hole 49. The adjusting rod 47 and the trigger rod 26 can be operated from the outside, which is more convenient to use. Secondly, a limit block 50 is fixedly installed on the inner side of the fixed frame 40. When the mounting plate 31 slides downward and contacts with the limit block 50, it stops. Therefore, each time the dye is recovered, the descending distance of the mounting plate 31 is a fixed value, and the increased resistance of the trigger rod 26 is also the same, so that the dyeing time is more accurate.

[0057] Embodiment 2

[0058] In the embodiment, the dyeing container 3 is used to place the dye, and can also be used as a flushing container. First, a drain pipe 51 is installed on one side of the dyeing container 3, and a drain valve 52 is installed on the outer wall of the drain pipe 51. The bottom of the drain pipe 51 is connected to a drain box 53. Therefore, after dyeing, after the dye is recovered, flushing water can be placed in the dyeing container 3. The flushing time can be achieved by the method of embodiment one, so that excessive flushing can be reduced and the dyeing quality of the slice can be further improved. After flushing, the drain valve 52 is opened, and the waste water generated by flushing can enter the drain box 53 through the drain pipe 51 for centralized storage.
