Description

Technical Field

[0001] This utility model relates to the field of dehydration technology, and in particular to a high-efficiency dehydration device for pathological tissues. Background Technology

[0002] Tissue dehydration is a crucial step in pathological slide preparation, involving the gradual replacement of water within the tissue with a gradient of alcohol (e.g., 70%-100%) to prepare for subsequent paraffin penetration. Its core purpose is to remove water, harden the tissue, and prevent cell deformation. Incomplete dehydration leads to poor paraffin penetration, affecting slide quality. It is usually linked to the clearing step (using xylene instead of alcohol), and the entire process requires strict time control (from several hours to overnight). Excessive dehydration can cause tissue fragility.

[0003] Currently, dehydration equipment is required as an auxiliary operation when dehydrating pathological tissues.

[0004] The existing technology disclosure number CN222599300U is a high-efficiency pathological tissue dehydration device, which includes a shell, a fixing frame and a first motor, etc. Multiple fixing frames are connected to the lower side of the shell, and the first motor is connected to each fixing frame.

[0005] This device can automatically move pathological tissues to dehydrating agents of different concentrations, improving the dehydration efficiency of pathological tissues. However, in practical applications, when there are too many pathological tissue samples (such as large-scale biopsies or surgical specimens), due to the limited dehydration capacity at one time, it needs to be processed in batches. It is necessary to wait for the previous pathological tissue sample to be dehydrated before the next batch of pathological tissue samples can be dehydrated, resulting in low batch sample processing efficiency. Therefore, an improvement is proposed. Utility Model Content

A plurality of storage tanks are uniformly fixedly connected to the top edge of the frame, and a solenoid valve is fixedly connected to each of the plurality of storage tanks and adjacent solution cylinders.

[0009] Furthermore, a density sensor is fixedly installed on one inner wall of each of the multiple solution cylinders, and a drain pipe is fixedly connected to the bottom of each of the multiple solution cylinders.

[0010] Furthermore, each of the liquid inlets of the storage tanks is threaded with a cap, which can seal the storage tank.

[0011] Furthermore, the lifting assembly includes an electric push rod, which is fixedly installed at the bottom center of the frame. The movable end of the electric push rod passes through the frame and is fixedly connected to a housing. Two guide rods are symmetrically fixedly connected to the bottom of the housing, and the guide rods pass through the frame and are slidably connected to the frame. The guide rods ensure the stability of the housing movement.

[0012] Furthermore, the rotating assembly includes a second motor, which is fixedly installed inside the housing. The driving end of the second motor is fixedly connected to a first gear, and the outer surface of the first gear is meshed with a second gear. The mounting shaft of the second gear passes through the housing and is fixedly connected to the cover plate, enabling it to drive the cover plate to rotate.

The cover 7 is designed to facilitate the addition of solution.

[0027] A lifting assembly is installed in the middle area of ​​the frame 1. A rotating assembly is fixedly installed at the movable end of the lifting assembly. A cover plate 8 is fixedly installed at the movable end of the rotating assembly. The lifting assembly includes an electric push rod 9, which is fixedly installed at the bottom center of the frame 1. The movable end of the electric push rod 9 passes through the frame 1 and is fixedly connected to a housing 19. Two guide rods 20 are symmetrically fixedly connected to the bottom of the housing 19, and the guide rods 20 pass through the frame 1 and are slidably connected to the frame 1. The rotating assembly includes a second motor 17, which is fixedly installed inside the housing 19. A first gear 15 is fixedly connected to the drive end of the second motor 17. A second gear 18 is meshed with the outer surface of the first gear 15. The mounting shaft of the second gear 18 passes through the housing 19 and is fixedly connected to the cover plate 8. The mounting shaft of the second gear 18 is rotatably connected to the housing 19. The mounting shaft of the second gear 18 and the housing 19 are connected by a ball bearing. The inner ring of the bearing is fixedly connected to the mounting shaft, and the outer ring of the bearing is fixedly connected to the housing 19 to reduce the rotational resistance of the second gear 18.

[0028] A first motor 12 is fixedly installed inside the cover plate 8. A drive gear 4 is fixedly connected to the drive end of the first motor 12, and the drive gear 4 passes through the cover plate 8 and is rotatably connected to it. The mounting shaft of the drive gear 4 is connected to the cover plate 8 via a ball bearing. The inner ring of the bearing is fixedly connected to the mounting shaft, and the outer ring of the bearing is fixedly connected to the cover plate 8. Multiple driven gears 5 are meshed on the outer surface of the drive gear 4, and the mounting shafts of the driven gears 5 pass through the cover plate 8 and are rotatably connected to it. The cover plate 8 is connected to the cover plate 8 by a sealed bearing. The inner ring of the bearing is fixedly connected to the mounting shaft of the driven gear 5, and the outer ring of the bearing is fixedly connected to the cover plate 8.

Through the fastening and fixing, the buckle plate 13 and the metal frame 2 can be connected and separated, which is convenient for the placement and removal of samples.

[0029] Working principle: The concentration of the solution in solution cylinder 3 gradually increases counterclockwise, and the same applies to storage tank 6. During dehydration, the sample frame containing the sample is hung on hook 16. The second motor 17 operates, driving the first gear 15 to rotate. The first gear 15 drives the second gear 18 to rotate, which in turn drives the cover plate 8 to rotate, thereby moving multiple driven gears 5. This moves the sample frame to solution cylinder 3, where the concentration is lowest. Then, the electric push rod 9 lowers the housing 19 and cover plate 8 until the cover plate 8 covers solution cylinder 3, immersing the sample in the solution. Then, the first motor 12 operates... The driving gear 4 rotates, which in turn drives four driven gears 5 to rotate. The driven gears 5 rotate the sample frame through the hook 16. After a preset time, the sample frame is transferred to the next solution cylinder 3. The above operation is repeated. When the sample frame returns to the loading station, it is removed and replaced with a new sample frame. When the density sensor 11 detects that the solution concentration in the solution cylinder 3 is lower than the set value, the electric control valve controls the drain pipe 10 to open, allowing the solution to drain into the external collection container. After completion, the valve is closed. Then, the corresponding solenoid valve 14 opens, and the solution in the corresponding storage tank 6 enters the solution cylinder 3. After a set time, the solenoid valve 14 closes.

[0030] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the electric push rod 9, density sensor 11, first motor 12, solenoid valve 14, second motor 17 and electric control valve to facilitate overall control.
