[0027] Furthermore, in this embodiment, the first dehydration component 201 includes a turntable 2011 and a plurality of reagent cylinders 2012. The plurality of reagent cylinders 2012 are arranged at intervals along the circumferential direction of the turntable 2011 on the turntable 2011, and the plurality of reagent cylinders 2012 are detachably connected to the turntable 2011; the turntable 2011 is rotatably connected to the bracket assembly 10, and the reagent cylinder 2012 is used to hold reagents; by the detachable connection between the reagent cylinder 2012 and the turntable 2011, thus, it is convenient to replace the reagents held in the reagent cylinder 2012.

[0028] By rotating the turntable 2011, the reagent cylinder 2012 is driven to rotate, thus, it is convenient for the lifting mechanism 30 to place the dehydration basket into the reagent cylinder 2012 to dehydrate the specimen tissue placed in the dehydration basket.

[0029] Continue to refer to Figure 2, in this embodiment, a driving mechanism is provided at the bottom end of the turntable 2011, and the driving mechanism is used to drive the turntable 2011 to rotate.

[0030] Among them, the driving mechanism includes a driving motor 204, a driving gear 205 and a driven gear 206. The output end of the driving motor 204 extends upward along the central axis direction of the turntable 2011. The bottom end of the driving motor 204 is connected to the mounting plate 103. A through hole 1011 extending along the central axis direction of the turntable 2011 is formed in the support plate 101. The output end of the driving motor 204 is connected to the driving gear 205.

During use, the driving motor 204 drives the driving gear 205 to rotate, the driving gear 205 drives the driven gear 206 to rotate, and the driven gear 206 drives the turntable 2011 to rotate.

[0031] Continue to refer to Figure 1 , in this embodiment, the reagent cylinder 2012 includes a first cylinder body 2013 and a first cylinder cover 2014 adapted to the first cylinder body 2013. The first cylinder cover 2014 covers the first cylinder body 2013. A volume scale is provided on the first cylinder body 2013; by providing the volume scale, thus, it is convenient to clearly understand the volume of the reagent contained in the reagent cylinder 2012.

[0032] Among them, a handle is provided on the outer peripheral wall of the first cylinder body 2013, and the handle and the volume scale are arranged at intervals along the circumferential direction of the first cylinder body 2013; by providing the handle, thus, it is convenient to take and place the reagent cylinder 2012, and the convenience of taking the reagent cylinder 2012 is improved.

[0033] Furthermore, in this embodiment, the reagent cylinder 2012 is made of a transparent material, and the material required for the reagent cylinder 2012 needs to meet the requirements of acid and alkali resistance and corrosion resistance; by using a transparent material for the reagent cylinder 2012, thus, the immersion degree of the specimen tissue and the turbidity of the reagent can be visually observed at any time, which is convenient for judging the availability of the reagent.

[0034] Further, in this embodiment, the second dehydration assembly 202 includes a housing 2021 and a cylinder assembly. The housing 2021 is adapted to the turntable 2011. The bottom end of the housing 2021 is connected to the support assembly 10. The turntable 2011 is received in the housing 2021. The turntable 2011 can rotate relative to the housing 2021. The housing 2021 and the turntable 2011 jointly enclose a receiving cavity 203. A plurality of reagent cylinders 2012 are received in the receiving cavity 203. An operation hole 2026 extending along the central axis direction of the housing 2021 is formed at the top end of the housing 2021. The operation hole 2026 communicates with the receiving cavity 203. The cylinder assembly is disposed at the top end of the housing 2021. The cylinder assembly is detachably connected to the housing 2021. By detachably connecting the cylinder assembly to the housing 2021, it is thus convenient to maintain the cylinder assembly.

[0035] By forming the operation hole 2026 in the housing 2021, it is thus convenient for the lifting mechanism 30 to operate on the reagent cylinder 2012 in the receiving cavity 203.

[0036] Continue to refer to Figure 1 , in this embodiment, a notch 2027 extending along the central axis direction of the housing 2021 is formed in the housing 2021. The notch 2027 penetrates the housing 2021 along the central axis direction of the housing 2021. The notch 2027 and the operation hole 2026 are arranged at intervals along the circumferential direction of the housing 2021. By forming the notch 2027, it is thus convenient to replace the reagent cylinder 2012 in the receiving cavity 203.

[0037] During use, when the turntable 2011 rotates to drive the reagent cylinder 2012 in the receiving cavity 203 to rotate and the reagent cylinder 2012 to be used rotates to directly below the operation hole 2026, the turntable 2011 stops rotating. At this time, the lifting mechanism 30 extracts the first cylinder cover 2014 of the reagent cylinder 2012 to be used from the operation hole 2026 through the operation hole 2026, that is to say, opens the first cylinder cover 2014 of the reagent cylinder 2012 to be used. Then, the turntable 2011 continues to rotate. When the reagent cylinder 2012 to be used rotates to the notch 2027, the turntable 2011 stops rotating. The lifting mechanism 30 inserts the dehydration basket into the first cylinder body 2013 of the reagent cylinder 2012 to be used through the notch 2027. Then, the dehydration basket rotates and stirs in the first cylinder body 2013.

[0038] Further, in this embodiment, the cylinder body assembly includes a plurality of reagent cylinders 2012 and a plurality of wax cylinders 2022. The plurality of reagent cylinders 2012 and the plurality of wax cylinders 2022 are all arranged at intervals along the circumferential direction of the housing 2021.

[0039] Specifically, the wax cylinder 2022 is used to hold paraffin wax. To facilitate the melting of the paraffin wax, a heating mechanism is provided at the bottom of the wax cylinder 2022. The heating mechanism is used to heat the wax cylinder 2022 to melt the paraffin wax inside the wax cylinder 2022. Among them, the heating mechanism can control the heating temperature, thereby avoiding the volatilization of the paraffin wax at high temperatures.

[0040] Further, the wax cylinder 2022 includes a second cylinder body 2023 and a second cylinder cover 2024 adapted to the second cylinder body 2023. The second cylinder cover 2024 is covered on the second cylinder body 2023.

[0041] Among them, the second cylinder body 2023 is made of a metal material, and a handle is provided on the outer peripheral wall of the second cylinder body 2023. By providing the handle, it is convenient to take the wax cylinder 2022; at the same time, it is convenient to replace the paraffin wax inside the wax cylinder 2022.

[0042] In some other embodiments, the cylinder assembly may only include a plurality of wax cylinders 2022, and the plurality of wax cylinders 2022 are arranged at intervals along the circumferential direction of the housing 2021.

[0043] Continue to refer to Figure 1 , in this embodiment, the lifting mechanism 30 includes a rotating shaft 301, at least one lid-lifting assembly 302, and at least one basket assembly 303. One end of the rotating shaft 301 is connected to the bracket assembly 10 through the dehydration mechanism 20. The rotating shaft 301 can rotate relative to the bracket assembly 10. The lid-lifting assembly 302 is arranged on the rotating shaft 301. The rotating shaft 301 can drive the lid-lifting assembly 302 to rotate. The lid-lifting assembly 302 is used to open or cover the first cylinder cover 2014 or the second cylinder cover 2024; the basket assembly 303 is arranged on the rotating shaft 301. The basket assembly 303 and the lid-lifting assembly 302 are arranged at intervals along the circumferential direction of the rotating shaft 301. The rotating shaft 301 can drive the basket assembly 303 to rotate. The basket assembly 303 is used to put the specimen tissue into the reagent cylinder 2012 or the wax cylinder 2022.

[0044] The working process of inserting the dehydration basket into the second cylinder body 2023 is as follows: The rotating shaft 301 rotates, driving the lid-lifting assembly 302 and the basket assembly 303 to rotate. When the lid-lifting assembly 302 rotates to directly above the wax cylinder 2022 to be used, the rotating shaft 301 stops rotating, and the lid-lifting assembly 302 opens the second cylinder cover 2024 of the wax cylinder 2022; then, the rotating shaft 301 rotates. When the basket assembly 303 rotates to directly above the wax cylinder 2022 with the second cylinder cover 2024 opened, the rotating shaft 301 stops rotating, and the basket assembly 303 inserts the dehydration basket into the second cylinder body 2023.

[0045] Continue to refer to Figure 2, in this embodiment, a control motor 304 is provided at the bottom end of the rotating shaft 301. The bottom end of the control motor 304 is connected to the mounting plate 103. The output end of the control motor 304 is connected to the rotating shaft 301 through the through hole 1011, and the output end of the control motor 304 extends upward along the central axis of the rotating shaft 301. During use, the control motor 304 drives the rotating shaft 301 to rotate, and the rotation of the rotating shaft 301 drives the cover-lifting assembly 302 and the basket-lifting assembly 303 to rotate.

[0046] Exemplarily, the cover-lifting assembly 302 and the basket-lifting assembly 303 are respectively connected to the rotating shaft 301 through brackets. Among them, the bracket can be U-shaped, the bracket can also be T-shaped, and the bracket can also be I-shaped. This embodiment does not limit this.

[0047] In some implementable ways, a fixing plate 3011 is provided at the top end of the rotating shaft 301, and the fixing plate 3011 is parallel to the support plate 101. Among them, the fixing plate 3011 can be circular, and the fixing plate 3011 can also be rectangular. In the implementable way where the fixing plate 3011 is circular, the central axis of the fixing plate 3011 is collinear with the central axis of the rotating shaft 301, and the cover-lifting assembly 302 and the basket-lifting assembly 303 are respectively provided on the fixing plate 3011.

[0048] In some other embodiments, the lifting mechanism 30 may include a plurality of cover-lifting assemblies 302 and a plurality of basket-lifting assemblies 303. The plurality of cover-lifting assemblies 302 are arranged at intervals around the circumference of the rotating shaft 301, and the plurality of basket-lifting assemblies 303 are arranged at intervals around the circumference of the rotating shaft 301.

[0049] Further, in this embodiment, the cover-lifting assembly 302 includes a cover-lifting arm assembly and a first lifting mechanism 3024 for driving the cover-lifting arm assembly to lift. One end of the first lifting mechanism 3024 is connected to the rotating shaft 301, and the other end of the first lifting mechanism 3024 is connected to the cover-lifting arm assembly. The cover-lifting arm assembly extends radially outward along the rotating shaft 301; the first lifting mechanism 3024 drives the cover-lifting arm assembly to move along the central axis direction of the rotating shaft 301, so that the cover-lifting arm assembly lifts or covers the first cylinder head 2014 or the second cylinder head 2024.

[0050] Specifically, the first lifting mechanism 3024 includes a cylinder. The cylinder is connected to the fixing plate 3011. The piston rod of the cylinder extends downward along the central axis of the rotating shaft 301, and the piston rod of the cylinder is connected to the cover-lifting arm assembly. During use, the piston rod drives the cover-lifting arm assembly to move.

[0051] In some other embodiments, the first lifting mechanism 3024 may also use a lead screw.

[0052] For the convenience of description, the following describes taking the first lifting mechanism 3024 using a cylinder as an example.

[0053] Furthermore, in the present embodiment, the cover-opening arm assembly includes a slide plate 3021 and a cover-opening member 3022 . The cover-opening member 3022 is disposed at the bottom end of the slide plate 3021 . The cover-opening member 3022 is used to open the reagent tank 2012 or the wax tank 2022 .

[0054] Specifically, the slide plate 3021 extends outward radially along the rotating shaft 301, the top end of the slide plate 3021 is connected to the piston rod of the cylinder, and the end of the slide plate 3021 facing the rotating shaft 301 is provided with a groove adapted to the outer peripheral wall of the rotating shaft 301, and the inner wall of the groove is in contact with the outer peripheral wall of the rotating shaft 301. Therefore, when the slide plate 3021 slides along the central axis direction of the rotating shaft 301, the rotating shaft 301 guides the slide plate 3021.

[0055] Furthermore, in the present embodiment, the cover opening piece 3022 is block-shaped, and a through groove 3023 is provided on the side of the cover opening piece 3022 away from the slide plate 3021, and the through groove 3023 is arc-shaped. The first cylinder cover 2014 and the second cylinder cover 2024 are both provided with an extraction part 2025 adapted to the through groove 3023, and the extraction part 2025 can be inserted into the through groove 3023, and the extraction part 2025 can slide along the extension direction of the through groove 3023; by providing the through groove 3023 on the cover opening piece, it is convenient to connect the extraction part 2025 with the through groove 3023 during use, thereby facilitating the opening of the reagent cylinder 2012 or the wax cylinder 2022.

[0056] The cover opening piece 3022 is arranged at the bottom end of the slide plate 3021. During use, the extraction part 2025 is located directly below the cover opening piece 3022. The piston rod of the cylinder drives the slide plate 3021 to slide downward along the rotating shaft 301, so that the cover opening piece 3022 is connected to the extraction part 2025. As a result, the piston rod drives the cover opening piece 3022 and the first cylinder cover 2014 or the second cylinder cover 2024 to move upward. At this time, the reagent cylinder 2012 or the wax cylinder 2022 is opened.

[0057] In this embodiment, a through groove 3023 is provided at one end of the cover opening member 3022 away from the slide plate 3021. The through groove 3023 extends along the width direction of the cover opening member 3022 and passes through the cover opening member 3022. The through groove is arc-shaped, and the arc of the through groove is generally consistent with the rotation arc of the extraction part 2025 around the rotating shaft 301. Therefore, the extraction part 2025 can slide along the through groove 3023.

[0058] Exemplarily, taking the plane parallel to the central axis of the reagent cylinder 2012 as the cross-section, the cross-sectional shape of the extraction part 2025 can be T-shaped. Of course, the cross-sectional shape of the extraction part 2025 can also be I-shaped. In an implementable manner where the cross-sectional shape of the extraction part 2025 is T-shaped, clamping parts are provided on both opposite sides of the side of the through groove 3023 away from the sliding plate 3021. The clamping parts extend inwards along the length direction of the lid-opening part 3022. The extraction part 2025 is inserted into the through groove 3023, and the end of the extraction part 2025 abuts against the clamping parts. Thus, when the extraction part 2025 is moved upwards, the extraction part 2025 is prevented from sliding out of the through groove 3023. During use, when the sliding plate 3021 drives the lid-opening part 3022 to move to the position where the opening end of the through groove 3023 is aligned with the extraction part 2025 on the first cylinder head 2014, the sliding plate 3021 stops sliding. At this time, the turntable 2011 rotates, so that the extraction part 2025 on the first cylinder head 2014 is inserted into the through groove 3023. After the extraction part 2025 on the first cylinder head 2014 slides along the through groove 3023 to a certain position, the turntable 2011 stops rotating, and the extraction part 2025 on the first cylinder head 2014 is clamped with the through groove 3023. Then, the sliding plate 3021 drives the lid-opening part 3022 to move upwards, and the first cylinder head 2014 of the reagent cylinder 2012 is opened.

[0059] The working process of the lid-lifting assembly 302 for opening the second cylinder head 2024 of the wax cylinder 2022 is as follows: When the sliding plate 3021 drives the lid-opening part 3022 to move to the position where the opening end of the through groove 3023 is aligned with the extraction part 2025 on the second cylinder head 2024, the sliding plate 3021 stops sliding. At this time, the rotating shaft 301 rotates, so that the extraction part 2025 on the second cylinder head 2024 is inserted into the through groove 3023, and the extraction part 2025 on the second cylinder head 2024 is clamped with the through groove 3023. Then, the sliding plate 3021 drives the lid-opening part 3022 to move upwards, and the second cylinder head 2024 of the wax cylinder 2022 is opened.

[0060] In other embodiments, the lid-opening part 3022 uses an electromagnet, and the extraction part 2025 is made of a metal material. During use, the piston rod of the air cylinder drives the sliding plate 3021 to slide downwards, so that the lid-opening part 3022 is attached to the extraction part 2025. The piston rod of the air cylinder stops moving. At this time, the lid-opening part 3022 is energized. Under the action of the electromagnetic force, the extraction part 2025 is adsorbed on the lid-opening part 3022. Then, the piston rod of the air cylinder drives the sliding plate 3021 to slide upwards, and the sliding plate 3021 drives the lid-opening part 3022 and the first cylinder head 2014 / second cylinder head 2024 to move upwards.

[0061] Continue to refer to Figure 1 and Figure 3In this embodiment, the basket lifting assembly 303 includes a basket lifting arm assembly and a second lifting mechanism 3035 for driving the basket lifting arm assembly to lift and lower. One end of the second lifting mechanism 3035 is connected to the rotating shaft 301, and the other end of the second lifting mechanism 3035 is connected to the basket lifting arm assembly. The basket lifting arm assembly extends radially outward along the rotating shaft 301, and the bottom end of the basket lifting arm assembly is used to connect with the dehydration basket; the second lifting mechanism 3035 drives the basket lifting arm assembly to move along the central axis direction of the rotating shaft 301, so that the basket lifting arm assembly places the dehydration basket containing the specimen tissue into the reagent tank 2012 or the wax tank 2022.

[0062] Among them, the structure of the second lifting mechanism 3035 is substantially consistent with that of the first lifting mechanism 3024, and the structure of the second lifting mechanism 3035 is not described in detail here.

[0063] Furthermore, in this embodiment, the basket arm assembly includes a connecting plate 3031, a sealing cover 3032 and a claw 3033. The sealing cover 3032 is arranged at the bottom end of the connecting plate 3031. The sealing cover 3032 is provided with a claw 3033 on the side of the sealing cover 3032 away from the connecting plate 3031. The claw 3033 is used to connect with the dehydration basket; the sealing cover 3032 is used to seal the first cylinder body 2013 or the second cylinder body 2023.

[0064] Specifically, the connecting plate 3031 extends outwardly along the radial direction of the rotating shaft 301, and one end of the connecting plate 3031 facing the rotating shaft 301 is provided with a curved surface that fits with the outer peripheral wall of the rotating shaft 301, and the second lifting mechanism 3035 is connected to the top of the connecting plate 3031. During use, the second lifting mechanism 3035 drives the connecting plate 3031 to slide along the rotating shaft 301; the curved surface fits with the outer peripheral wall of the rotating shaft 301, so that the rotating shaft 301 guides the connecting plate 3031.

[0065] Exemplarily, the top of the sealing cover 3032 is connected to the bottom of the connecting plate 3031, and the hanging claw 3033 is arranged at the bottom of the sealing cover 3032, and the dehydration basket is hung on the hanging claw 3033. During use, the sealing cover 3032 is located directly above the first cylinder 2013 or the second cylinder 2023 to be used, and the second lifting mechanism 3035 drives the connecting plate 3031 to slide downward along the rotating shaft 301, so that the dehydration basket is inserted into the first cylinder 2013 / the second cylinder 2023, and the sealing cover 3032 is covered on the first cylinder 2013 / the second cylinder 2023 to achieve dehydration of the sample tissue.

[0066] In some achievable embodiments, the sealing cover 3032 and the connecting plate 3031 are connected via a fixing rod 3034 , and a central axis of the fixing rod 3034 is arranged parallel to a central axis of the sealing cover 3032 .

[0067] To avoid designing multiple sealing caps 3032 with different sizes, taking the plane parallel to the support plate 101 as the cross-section, the cross-sectional area of the first cylinder body 2013 is made equal to the cross-sectional area of the second cylinder body 2023. Thus, the consistency of the use of the sealing cap 3032 is improved.

[0068] The usage process of the dehydration device 1 provided in this embodiment: By rotating the rotating shaft 301, the cover-lifting assembly 302 and the basket assembly 303 are driven to rotate. The cover-lifting assembly 302 is located directly above the operation hole 2026, and the basket assembly 303 is located directly above the notch 2027. The rotating shaft 301 stops rotating; then, the dehydration basket containing the sample tissue is hung on the hanging claws 3033, and the turntable 2011 rotates to drive the reagent cylinder 2012 in the accommodation cavity 203 to rotate. When the reagent cylinder 2012 to be used rotates to directly below the operation hole 2026, the turntable 2011 stops rotating. At this time, the first lifting mechanism 3024 drives the sliding plate 3021 and the cover-opening member 3022 to move downward along the central axis direction of the rotating shaft 301, and the extraction part 2025 is engaged with the through groove 3023. Then, the sliding plate 3021 drives the cover-opening member 3022 and the first cylinder cover 2014 to move upward along the central axis direction of the rotating shaft 301, and the first cylinder cover 2014 of the reagent cylinder 2012 is opened; the turntable 2011 rotates. When the reagent cylinder 2012 with the first cylinder cover 2014 opened rotates to the notch 2027, the second lifting mechanism 3035 drives the connecting plate 3031 to slide downward along the central axis direction of the rotating shaft 301. At this time, the dehydration basket is inserted into the first cylinder body 2013, and the sealing cap 3032 is covered on the first cylinder body 2013. The heating mechanism heats the wax cylinder 2022, and the dehydration basket rotates and stirs and performs vacuum pumping in the first cylinder body 2013; then, the second lifting mechanism 3035 drives the connecting plate 3031 to slide upward. When the connecting plate 3031 drives the dehydration basket to move upward and the dehydration basket leaves the liquid surface, after 10 - 60S of draining and shaking the liquid, it rises to the highest position; then, the turntable 2011 rotates. When the reagent cylinder 2012 with the first cylinder cover 2014 opened rotates to directly below the operation hole 2026, the turntable 2011 stops rotating. At this time, the first lifting mechanism 3024 drives the sliding plate 3021 to slide, and the sliding plate 3021 drives the first cylinder cover 2014 to move, and the first cylinder cover 2014 is covered on the reagent cylinder 2012 with the cover opened; then, the turntable 2011 drives the reagent cylinder 2012 in the accommodation cavity 203 to rotate, and the cover-lifting assembly 302 opens the first cylinder cover 2014 of the next reagent cylinder 2012 to be used. When rotating the turntable 2011 and the reagent cylinder 2012 with the first cylinder cover 2014 opened rotates to the notch 2027, the basket assembly 303 inserts the dehydration basket into the first cylinder body 2013 for dehydration; when running to the last wax cylinder 2022 in sequence, the dehydration of the sample tissue is completed, and the dehydration basket is stored in the last wax cylinder 2022, waiting for the user to extract.
