One end of the metal rod 9 far from 5 is fixedly connected with a scraping plate 12. A conveying pipe 13 is fixedly connected to the right side of the dispersion tank 3. One end of the conveying pipe 13 far from the dispersion tank 3 is fixedly connected with a collection box 14. A filter box 15 is slidably connected to the inside of the collection box 14. Two fixing blocks 16 are fixedly connected to the rear side of the filter box 15. Two fixing components are arranged at the rear side of the collection box 14. The fixing components are used for quickly disassembling the filter box 15. A support plate 24 is fixedly connected to the bottom of the collection box 14. Four support columns 26 are fixedly connected to the periphery of the bottom of the support plate 24.
[0033] Specifically, the bottom plate 1 serves as the foundation of the entire device, providing a stable support platform. The support legs 2 connect the bottom plate 1 and the dispersion tank 3, increasing the stability of the device. The dispersion tank 3 is used to accommodate the stem cell samples to be processed, and realizes the mixing and dispersion of cells through the internal stirring mechanism. The motor 4 drives the stirring mechanism to operate, providing power for cell dispersion. The stirring shaft 5 is driven by the motor 4 to rotate, driving the stirring rods 6 to perform stirring actions. The stirring rods 6 are connected to the stirring shaft and stir the cell samples by rotating to promote the uniform dispersion of cells. The connecting rods 7 connect the stirring rods 6 and the fixing plate 8, transmitting the stirring torque. The metal rods 9 slide inside the fixing plate 8, driving the scraping plates 12 to perform cleaning actions. The first spring 10 provides an elastic force, making the scraping plates closely adhere to the inner wall of the dispersion tank 3, effectively removing the attached cells. The limiting blocks 11 limit the moving range of the metal rods 9, ensuring the normal operation of the scraping plates 12. The scraping plates 12 clean the inner wall of the dispersion tank 3 as the metal rods 9 slide, preventing cell adhesion. The conveying pipe 13 connects the dispersion tank 3 and the collection box 14, and is used to convey the processed cell samples to the collection box 14. The filter box 15 is located inside the collection box 14 and is used for filtering and separating different components in the cell samples. The fixing blocks 16 cooperate with the fixing components to quickly install or disassemble the filter box 15. The support plate 24 provides additional support for the collection box.
[0034] Refer to Figure 2 、 Figure 4 and Figure 5, The fixing component includes a housing 17, the outside of the housing 17 is fixedly connected to the rear side of the collection box 14, two sliding grooves 18 are opened inside the housing 17, two plug-in blocks 20 are slidably connected inside the fixing block 16, a baffle 21 is fixedly connected to one side of the plug-in block 20, a pull rope 23 is fixedly connected to the middle of the baffle 21, one end of the pull rope 23 is fixedly connected to a second handle 29, a second spring 19 is sleeved outside the pull rope 23, and a rotating shaft 22 is arranged outside the pull rope 23.
[0035] Specifically, the housing 17 is fixed to the rear side of the collection box 14, providing a protective and supporting structure for other parts of the fixing component. The sliding grooves 18 are opened inside the housing 17, providing a sliding path for the plug-in blocks 20, enabling the plug-in blocks 20 to smoothly move inside the fixing block 16. The second spring 19 is sleeved outside the pull rope 23, providing an elastic force, enabling the plug-in blocks 20 to automatically rebound to their original positions after being pulled out, thereby fixing the filter box 15. The plug-in blocks 20 slide inside the fixing block 16, and through cooperation with the sliding grooves 18, the fixing or release of the filter box 15 is achieved. The baffle 21 is fixedly connected to one side of the plug-in block 16, possibly used to prevent the plug-in block 16 from sliding out excessively and keeping it in an appropriate position. The rotating shaft 22 is used to support and guide the movement of the pull rope 23, possibly to change the direction of the pull rope 23 or reduce friction. One end of the pull rope 23 is connected to the baffle 21, and the other end is connected to the second handle 29. By pulling the second handle 29, the movement of the plug-in blocks 20 in the sliding grooves 18 can be controlled, thereby achieving the fixing or release of the filter box 15.
[0036] Refer to Figure 1 , Figure 3 and Figure 5 , a feed inlet 27 is fixedly connected to the top of the dispersion tank 3, a discharge pipe 25 is fixedly connected to the bottom of the collection box 14, one end of the first spring 10 is fixedly connected to the side of the scraping plate 12 away from the dispersion tank 3, the other end of the first spring 10 is fixedly connected to the side of the fixing plate 8 away from 5, the scraping plate 12 abuts against the inner wall of the dispersion tank 3, the 5 bottom end is rotatably connected to the inner bottom wall of the dispersion tank 3, one end of the second spring 19 is fixedly connected to the middle side of the baffle 21, the other end of the second spring 19 is fixedly connected to the inner wall of the sliding groove 18, both ends of the rotating shaft 22 are rotatably connected inside the housing 17, the outside of the plug-in block 20 is slidably connected inside the housing 17, and a first handle 28 is fixedly connected to the front side of the filter box 15.
[0037] Specifically, the discharge pipe 25 is fixed to the bottom of the collection box 14 and is used to discharge the cell samples that have been filtered and sorted, facilitating collection and further processing. The feed inlet 27 is fixed to the top of the dispersion tank 3 and is used to inject the stem cell samples to be processed into the dispersion tank 3 for stirring and dispersion. One end of the first spring 10 is fixed to the side of the scraper away from the dispersion tank 3, and the other end is fixed to the side of the fixed plate 8 away from the stirring shaft 5. The function of the first spring 10 is to keep the scraper 12 in close contact with the inner wall of the dispersion tank 3, ensuring that the cells attached to the inner wall can be effectively removed during the stirring process, preventing cell adhesion and accumulation. The bottom end of the stirring shaft 5 is rotatably connected to the inner bottom wall of the dispersion tank 3. Driven by the motor 4, the stirring shaft 5 drives the stirring rod 6 to rotate, realizing uniform stirring and dispersion of the cell samples. One end of the second spring 19 is fixed to the middle of the baffle 21, and the other end is fixed to the inner wall of the chute 18. The function of the second spring 19 is to push the insertion block 20 back to its original position when the pull rope 23 is relaxed, thereby fixing the filter box 15. The first handle 28 is fixed to the front side of the filter box 15, and the operator can pull the first handle 28 to take out or put in the filter box 15, facilitating the replacement and maintenance of the filter box 15.
[0038] Working principle: Pour the cell mixture into the interior of the dispersion tank 3 from the feed inlet 27, start the motor 4 to drive the rotation of the rotating shaft 5, and then drive the rotation of the stirring rod 6 and the scraper 12 to fully stir and break up the cell clusters in the cell mixture in the dispersion tank 3. Under the action of the scraper 12, the waste of stem cells adhering to the inner side wall of the dispersion tank 3 is reduced. If the scraper 12 is worn, the first spring 10 will play its role to ensure that the scraper 12 is closely attached to the inner wall of the dispersion tank 32. After the breaking-up is completed, the cell mixture will be transported to the interior of the collection box 14 through the delivery pipe 13 and flow into the interior of the filter box 15. Under the action of the filter box 15, the cell mixture flows through the filter holes at the bottom of the filter box 15 into the discharge pipe 25 and is discharged, while the stem cells are left inside the filter box 15. When it is necessary to take out the separated stem cells, first pull the second handle 29, which then drives the pull rope 23 to move outwards, then drives the baffle 21 to move inside the chute 18, compressing the second spring 19 at the same time. The insertion block 20 also moves inside the chute 18 until the insertion block 20 completely leaves the inside of the fixing block 16. At this time, the filter box 15 can be taken out, and the disassembly is completed. When installation is required, put the filter box 15 into the interior of the collection box 14 and align the fixing block 16 with the card slot inside the housing 17. At this time, release the second handle 29. Under the action of the second spring 19, the baffle 21 is pushed to slide inside the chute 18, and then the insertion block 20 is re-inserted into the inside of the fixing block 16, and the installation is completed at this time.
