Description

Technical Field

[0001] This utility model relates to the field of tissue dehydration machine technology, and in particular to a modular and expandable tissue dehydration machine. Background Technology

[0002] For pathological diagnosis of diseases, the first step is to fix, dehydrate, clear, and impregnate the submitted tissue specimens to prepare paraffin blocks for sectioning. Tissue dehydration machines automatically immerse human or animal tissues in various solvents according to a program to perform dehydration, clearing, and impregnation before pathological analysis. Therefore, it is necessary to use an automatic tissue dehydration machine to dehydrate the tissues.

[0003] Current conventional tissue dehydrators have shortcomings. The number of dehydration chambers or tanks used to hold tissues is usually fixed and cannot be expanded. This results in inflexibility when facing fluctuations in sample volume. For example, when encountering batch physical examinations, concentrated research sampling, or sudden surges in pathological testing needs, the equipment's processing capacity immediately reaches its limit. Users cannot increase the throughput per batch by adding modules. They are either forced to process the same batch of samples multiple times over multiple days, which not only significantly reduces work efficiency and extends the reporting cycle but may also introduce unnecessary operational errors due to batch processing, affecting the consistency of results; or they can only choose to abandon some tests, thus delaying the diagnosis or research process. Therefore, the fixed number of chambers has become a major bottleneck restricting laboratories from coping with peak workloads and improving overall operational efficiency.

[0004] To address the aforementioned problems, this invention proposes a modular and scalable tissue dehydrator. Utility Model Content

[0019] Please see Figure 1-5 This utility model provides a technical solution: a modular and expandable tissue dehydrator, including a dehydrator tank 1, with a protective door 20 rotatably mounted on the side wall of the tank 1. A rotating shaft 3 is rotatably mounted inside the tank 1, and multiple fixing plates 5 are fixedly mounted on the outer side of the shaft 3 via connecting rods 4. A motor 10 is fixedly mounted at the top of the tank 1, and the output shaft of the motor 10 is fixedly connected to the top of the rotating shaft 3. The motor 10 drives the rotating shaft 3 to rotate, providing a stable power source for subsequent centrifugal dehydration.

[0020] Multiple arc-shaped plates 6 are evenly threaded along the vertical direction on the outer side of the fixed plate 5. Multiple threaded grooves 18 are evenly formed on the outer wall of the fixed plate 5, and threaded rods 19 are threadedly connected to the threaded grooves 18. The threaded rods 19 are fixedly connected to the arc-shaped plates 6. A dehydration tank 7 is fixedly installed on the side of the arc-shaped plates 6 opposite to the fixed plate 5. A T-slot 8 is formed on one side of the arc-shaped plate 6, and a T-shaped plate 9 is fixedly installed on the other side of the arc-shaped plate 6. The T-slot 8 and the T-shaped plate 9 are interlocked.

[0021] By adopting the above technical solution, the installation of the basic dehydration module is realized through threaded connection. The plug-in design of T-slot 8 and T-plate 9 provides a standardized mechanical interface for the lateral expansion of dehydration tank 7 in the same row, which is the basis for realizing modular expansion.

[0022] The top of the T-slot 8 is provided with a locking structure for limiting the T-plate 9. The locking structure includes a limiting rod 11 and a return spring 12. A sliding groove 14 is provided at the top of each T-slot 8, and the limiting rod 11 is slidably installed inside the sliding groove 14. A guide slope is provided at one end of the limiting rod 11 corresponding to one end of the T-slot 8. A return spring 12 is fixedly installed inside the sliding groove 14, and the other end of the return spring 12 is fixedly connected to the limiting rod 11. A connecting groove 15 is provided on the upper surface of the arc-shaped plate 6 corresponding to the interior of the sliding groove 14. A pull rod 13 is slidably installed inside the connecting groove 15, and the bottom end of the pull rod 13 is fixedly connected to the limiting rod 11.

[0023] By adopting the above technical solution, the snap-fit ​​structure utilizes the elasticity of the spring and the guide of the inclined surface to achieve automatic locking when the expansion module is inserted, making the operation simple and quick; the locking can be easily released by pulling the pull rod 13, which facilitates the disassembly and maintenance of the module and greatly improves the efficiency of the expansion operation.

[0024] A water guide plate 2 is fixedly installed on the bottom surface of the dewatering machine tank 1, and the bottom end of the rotating shaft 3 is rotatably connected to the water guide plate 2 in a sealed manner. A water storage tank 16 is detachably installed on the outer wall of the dewatering machine tank 1 corresponding to the lower end of the water guide plate 2. The water storage tank 16 is connected to the inside of the dewatering machine tank 1 through multiple water passages 17 opened on the bottom side of the dewatering machine tank 1.

[0025] By adopting the above technical solution, the liquid separated by centrifugation can be efficiently collected into the water storage tank 16 through the water passage 17 under the guidance of the water guide plate 2, realizing the centralized collection of waste liquid. In addition, the water storage tank 16 is detachable, which is convenient for cleaning and maintains the cleanliness of the equipment and the continuity of operation.

[0026] Working principle: In operation, the operator first opens the protective door 20, which is rotated and installed on the side wall of the dehydrator tank 1, and carefully places the biological tissue samples that have undergone preliminary staining into each dehydration chamber 7. Then, the motor 10, which is fixedly installed at the top of the dehydrator tank 1, is started. The output shaft of the motor 10 drives the rotating shaft 3 to start rotating. The rotational motion of the rotating shaft 3 is transmitted to the fixed plate 5 through the connecting rod 4 on its outer side, which in turn drives the arc-shaped plate 6, which is connected to the fixed plate 5 by a thread, and the dehydration chamber 7 fixed on it to rotate at high speed. During this process, the centrifugal force generated forces the liquid components in the tissue sample to be separated through the wall of the dehydration chamber 7, thereby achieving efficient dehydration.

[0027] When the sample volume increases and the dehydration capacity needs to be expanded, a module expansion operation is performed: Take an arc-shaped plate 6 to be added, and precisely insert the T-shaped plate 9, which is fixedly installed on one side, into the opening of the T-slot 8 on the side wall of the arc-shaped plate 6. As the T-shaped plate 9 enters the T-slot 8, its top end will contact the guide slope at the end of the limiting rod 11, which is slidably installed in the sliding groove 14 at the top of the T-slot 8, and relative sliding will occur. This interaction will push the limiting rod 11 to retract into the sliding groove 14 against the elastic force of the return spring 12. The T-shaped plate 9 is fully inserted into the bottom of the T-slot 8 until its top end passes the limiting rod 11. When the lever 11 is in position, the thrust applied to the limiting lever 11 disappears. At this time, the return spring 12 immediately restores its deformation, driving the limiting lever 11 to pop outward and firmly lock its bottom against the upper surface of the T-shaped plate 9, thus forming a reliable mechanical interlock. This completes the rapid installation of a single dehydration module. If it is necessary to unload a certain arc plate 6, simply pull the pull rod 13, which is slidably installed in the connecting groove 15, vertically upward. The pull rod 13 directly drives the limiting lever 11, which is fixed to it, to retract completely into the sliding groove 14, so that its bottom is no longer in contact with the T-shaped plate 9. The T-shaped plate 9 can then be smoothly pulled out of the T-groove 8, achieving safe disassembly of the module. This modular expansion mechanism allows the number of dehydration tanks 7 to be flexibly increased according to actual needs, improving the unit batch processing capacity and task adaptability of the entire device.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
