Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a tumor pathology section dehydration device. Background Art

[0002] Dehydration is a key step in the preparation of pathological sections. The quality of dehydration will directly affect the preparation effect and the subsequent determination of tumor properties. Poor dehydration quality will lead to inaccurate judgment of the patient's condition.

[0003] Existing methods for dehydrating tumor slices generally include physical dehydration and chemical dehydration. Physical dehydration is generally performed through heating, vacuuming, and centrifugation. It is simple to operate, environmentally friendly, and causes relatively little damage to tissues. However, physical dehydration cannot completely remove all water from the tissue, especially for tissues with high water content. Physical dehydration also takes longer, requiring operators to observe for a long time, and requires high control of dehydration. Chemical dehydration, on the other hand, uses dehydrating agents to displace water from the tissue. The dehydrating agents penetrate into the tissue through osmosis, bind to or replace water molecules, thereby achieving a dehydration effect. This can more thoroughly remove water from the tissue, ensure the dryness of the tissue sample, and achieve the dehydration effect faster. However, chemical dehydration requires the use of large amounts of chemical reagents, which is costly and may have certain effects on the tissue.

[0004] Therefore, the present application designs a tumor pathology section dehydration device to solve the above technical problems. Summary of the Invention

[0041] In one embodiment of the present application, a connecting pump 44 is provided on the drain pipe 41 to facilitate the discharge of air or waste liquid in the dehydration cylinder 3.

[0042] A further optimized solution is provided, in which a connecting pipe 32 is fixedly connected to and communicates with the top of the dehydration box 31. The connecting pipe 32 extends out of the dehydration cylinder 3 and is rotatably connected to the dehydration cylinder 3. The end of the connecting pipe 32 located outside the dehydration cylinder 3 is transmission-connected to the transfer pipe of the centrifugal assembly 5, and the transfer pipe is connected to the connecting pipe 32 via the liquid inlet assembly 6. The connecting pipe 32 passes through the dehydration cylinder 3 and is rotatably connected to the dehydration cylinder 3, so that the centrifugal assembly 5 can drive the dehydration box 31 to rotate at high speed, centrifugally dehydrate the tissue samples in the dehydration box 31, and achieve preliminary physical dehydration. The transfer pipe can be detachably connected to the connecting pipe 32, which can be separated for easy loading and unloading, and transmits the centrifugal dehydration of the dehydration box 31 by the centrifugal assembly 5. At the same time, the transfer pipe is also connected to the liquid inlet assembly 6, which facilitates the injection of dehydrating agent into the dehydration cylinder 3, achieving chemical dehydration without disassembly.

[0043] A further optimized solution is provided, in which the transfer tube includes a transmission rod 53 fixedly connected to the output end of the centrifugal assembly 5, the bottom end of which is slidably connected to a transmission sleeve 54, which is in transmission connection with the top end of the connecting pipe 32; a liquid inlet chamber 55 communicating with the connecting pipe 32 is provided in the transmission rod 53, the liquid inlet chamber 55 is in communication with a liquid inlet box 56 rotatably connected to the transmission rod 53, and the liquid inlet assembly 6 is in communication with the liquid inlet box 56. The transmission rod 53 is fixedly connected to the output end of the centrifugal motor 52, and the transmission sleeve 54 at its bottom end can be detached from the top end of the connecting pipe 32 to facilitate transmission; at the same time, the liquid inlet box 56 rotatably connected to the transmission rod 53 is in communication with the liquid inlet assembly 6, and the dehydrating agent is fed from the liquid inlet assembly 6 into the liquid inlet box 56, then into the liquid inlet chamber 55 from the liquid inlet port 57, and then into the dehydration box 31 through the connecting pipe 32.

[0044] In one embodiment of the present application, the liquid inlet box 56 is fixed to the workbench 1 via a fixing rod, so that the liquid inlet box 56 and the transmission rod 53 can be rotated relative to each other while also enabling the dehydrating agent to be pumped in.

[0045] In one embodiment of the present application, a clearance groove 51 is provided on the workbench 1 , and the centrifugal motor 52 is installed in the clearance groove 51 .

[0046] In one embodiment of the present application, the top outer wall of the connecting tube 32 is configured to be prismatic, and the bottom inner cavity of the transmission sleeve 54 is designed to be prismatic to match the top of the outer wall of the connecting tube 32, so as to facilitate transmission and avoid slipping between the two.

[0047] In one embodiment of the present application, a flexible sealing ring is provided between the top of the inner cavity of the transmission sleeve 54 and the connecting pipe 32 to increase the sealing performance. When the transmission sleeve 54 is pressed down and sleeved on the connecting pipe 32, the sealing performance between the transmission sleeve 54 and the connecting pipe 32 is increased to prevent leakage of the dehydrating agent.

[0048] In a further optimized solution, the liquid inlet assembly 6 includes a first container 61 for holding a dehydrating agent and a second container 62 for holding a conditioning agent, which are disposed within the workbench 1. The first container 61 and the second container 62 are respectively connected to the inlet of a mixer 63 disposed within the workbench 1. The outlet of the mixer 63 extends out of the workbench 1 and is connected to the inner cavity of the liquid inlet box 56. The concentration of the dehydrating agent within the first container 61 is higher than the maximum concentration for chemical dehydration, while the conditioning agent can be mixed with the dehydrating agent to adjust its concentration. During use, the conditioning agent and the dehydrating agent are pumped in different proportions according to the concentration requirements, then mixed in the mixer 63 and fed into the liquid inlet box 56. The mixture is then transferred to the dehydration box 31 for chemical dehydration.

[0049] In one embodiment of the present application, the mixer 63 has the function of detecting the concentration of the dehydrating agent and is electrically connected to the control module, and can detect the concentration of the dehydrating agent in real time, thereby facilitating the control of the dehydration accuracy.

[0050] In a further optimization, the bottom end of the liquid inlet box 56 is rotatably connected to a lifting ring 58 coaxially arranged with the transmission rod 53. A plurality of telescopic rods 59 are evenly spaced at the bottom end of the lifting ring 58. The free ends of the telescopic rods 59 are downwardly directed and in driving connection with the top end of the transmission sleeve 54. The lifting ring 58 is rotatably connected to the lifting slot 510 at the bottom end of the liquid inlet box 56. The telescopic rods 59 drive the transmission sleeve 54 up and down, thereby connecting and disconnecting the transmission sleeve 54 from the connecting pipe 32.

[0051] In one embodiment of the present application, a plurality of receiving grooves 511 corresponding to the telescopic rod 59 are provided at the top of the transmission sleeve 54, and the output end of the telescopic rod 59 is fixedly connected to the bottom end of the receiving groove 511, so as to increase the lifting range of the transmission sleeve 54 and reduce the space required for the equipment.

[0052] To further optimize the solution, a mounting groove 21 is provided on the mounting block 2 to match the dehydration cylinder 3. A number of support springs 22 are provided at the bottom end of the mounting groove 21. The several support springs 22 are fixedly connected to the bottom end of the support plate 23 which is slidably connected in the mounting groove 21. After the dehydration cylinder 3 is installed in the mounting groove 21, it abuts against the support plate 23. The discharge pipe 38 at the bottom end of the dehydration cylinder 3 passes through the support plate 23 and is connected to the top end of the drain pipe 41. The dehydration cylinder 3 is embedded in the installation groove 21, and after installation, it abuts against the support plate 23. Then the mounting block 2 with the dehydration cylinder 3 installed is installed in the assembly groove 11. At this time, the connecting pipe 32 corresponds to the transmission sleeve 54, and the discharge pipe 38 at the lower end corresponds to the emptying pipe 41 up and down. Then the transmission sleeve 54 is pressed down on the connecting pipe 32, pressing the dehydration cylinder 3 to press the support plate 23 down, so that the discharge pipe 38 at the bottom end of the dehydration cylinder 3 is sealed and connected to the top of the emptying pipe 41, thereby realizing the connection between the dehydration cylinder 3 and the liquid inlet component 6 and the emptying component 4; and when the dehydration is completed, the transmission sleeve 54 rises and no longer presses the connecting pipe 32, the support spring 22 is reset, and the dehydration cylinder 3 is pushed up through the support plate 23, which is convenient for removal and improves convenience.

[0053] In a further optimized solution, the dehydration cylinder 3 includes an outer cylinder 35 that fits into the mounting groove 21 and abuts against the top of the support plate 23.

During dehydration, the outer cylinder 35 communicates with the drain pipe 41 through the discharge pipe 38, while the inner cylinder 36 communicates with the inner cavity of the outer cylinder 35 through a plurality of through holes 39. The top ends of the inner cylinder 36 and the outer cylinder 35 are flush, and the sealing cap 37 is detachably connected to the top ends of the inner cylinder 36 and the outer cylinder 35, sealing the top ends of the inner cylinder 36 and the outer cylinder 35. A sealed bearing is provided on the sealing cap 37, and the connecting pipe 32 passes through the sealed bearing for easy rotation.

[0054] In one embodiment of the present application, a plurality of dehydration holes 34 are formed through the dehydration box 31 to conveniently drain moisture from the tissue sample and achieve dehydration.

[0055] In one embodiment of the present application, the bottom ends of the inner cavities of the inner tube 36 and the outer tube 35 are both inclined toward the middle to avoid liquid accumulation.

[0056] To further optimize the solution, the locking assembly includes two locking rods 24 that slide symmetrically in the mounting block 2. The locking rods 24 extend out of the mounting block 2 and are engaged with the locking holes 12 set on the side walls of the assembly groove 11; the two locking rods 24 are respectively hinged with hinged rods 25 at one end away from the locking holes 12, and the hinged rods 25 are hinged to the control rod 26 that is slidably connected to the mounting block 2. The control rod 26 is slidably connected to the first sliding groove 211 in the mounting block 2, and the locking rod 24 is slidably connected to the second sliding groove 212 in the mounting block 2, and the first sliding groove 211 and the second sliding groove 212 are arranged vertically; the locking rod 24 is hinged to the control rod 26 through the hinge rod 25. When the control rod 26 slides along the first sliding groove 211, the angle of the hinge rod 25 between the locking rod 24 and the control rod 26 can be changed to drive the locking rod 24 to slide in the second sliding groove 212, and then the separation and locking of the locking rod 24 and the locking hole 12 can be controlled to realize the connection and separation of the mounting block 2 and the workbench 1.

[0057] Refer to the attached Figure 6 As shown, in one embodiment of the present application, the end face of the locking rod 24 facing the inner side of the workbench 1 is set as a slope, so that when the mounting block 2 slides into the assembly groove 11, it can be automatically pressed and will not get stuck, and when the mounting block 2 slides out of the assembly groove 11, it is stuck and self-locking is completed.

[0058] In a further optimized solution, a control slot 27 is formed on the side wall of the mounting block 2. A plurality of control springs 28 are disposed within the control slot 27. The control springs 28 are fixedly coupled to a control button 29 that is slidably coupled to the control slot 27. The control rod 26 extends into the control slot 27 and is fixedly coupled to the control button 29. The control button 29 is slidably coupled to the control slot 27. When the control button 29 is pressed, the control rod 26 is pushed to move, thereby pulling the locking rods 24 on both sides toward the center, separating the ends of the locking rods 24 from the locking holes 12, thereby unlocking the mounting block 2. When the control button 29 is released, the control spring 28 between the control button 29 and the control slot 27 and the return spring 210 between the control rod 26 and the first sliding slot 211 push the control rod 26 back to its original position, driving the locking rod 24 to move away from the control rod 26, pushing the locking rod 24 out of the second sliding slot 212 and engaging it in the locking hole 12, thereby locking the mounting block 2 to the workbench 1.

[0059] In one embodiment of the present application, a buckle 213 is provided on the outer wall of the mounting block 2 to facilitate the installation and removal of the mounting block 2 .

[0060] As a further optimization, a pressing plate 33 is slidably connected to the dehydration box 31, which presses the tissue sample against the top of the inner cavity of the dehydration box 31. The pressing plate 33 is slidably connected to the dehydration box 31, which can firmly fix tissue samples of different sizes and prevent them from shaking during dehydration and causing damage to the tissue samples.

[0061] In one embodiment of the present application, a plurality of dehydration holes 34 are also formed through the pressing plate 33 to facilitate the injection of dehydrating agent to immerse the tissue sample and perform chemical dehydration on the tissue sample.
