Description

Technical Field

[0001] The utility model relates to a filter separator, in particular to a stem cell filter separator, and belongs to the technical field of stem cell filter separation. Background Art

[0002] Stem cells are a type of cell with unlimited or immortal self-renewal capacity, capable of producing at least one type of highly differentiated daughter cells. Generally speaking, between stem cells and their terminally differentiated daughter cells lies an intermediate population of progenitor cells known as "committed progenitor cells," which have limited proliferation capacity and restricted differentiation potential. The function of these cell populations is to increase the number of differentiated cells produced after each stem cell division. Stem cells have the ability to self-renew, but their division is actually relatively asymmetric.

[0003] A Chinese patent application (CN201920072089.0) discloses a mesenchymal stem cell filter separator. The first filter can remove larger tissues, while the second filter can effectively separate mesenchymal stem cells. The filter adopts an inverted conical structure to increase the contact area between the tissue and the filter, improving filtration efficiency. However, existing stem cell filter separators, when in use, directly contact the secondary filter after primary filtration. This limited the usable surface area of ​​the secondary filter, causing stem cells to accumulate in one place, resulting in low filtration efficiency.

[0004] In order to solve the above technical problems, a stem cell filtration separator is proposed. Utility Model Content

[0005] In view of this, the present invention provides a stem cell filtration separator to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0027] The upper filter mechanism 10 includes an upper filter cartridge 11, a first filter screen 16 and a partition 19. A liquid inlet 12 for liquid inlet is integrally formed on one side of the upper filter cartridge 11. The liquid inlet 12 is hollow inside, and a spiral cooling pipe 13 is installed in the hollow part for cooling the liquid when it is inlet. A first fixing ring 15 is fixedly connected to one side of the upper filter cartridge 11. First bolts 17 are equidistantly threadedly connected to one side of the first filter screen 16. One end of the first bolt 17 is threadedly connected to the first fixing ring 15, which facilitates the installation of the first filter screen 16 on the upper filter cartridge 11. In the upper filter cartridge 11, the partition 19 can be fixed to one side of the interior of the upper filter cartridge 11 by bolts. A guide tube 34 is passed through the interior of the partition 19. A collecting portion 33 is integrally formed at one end of the guide tube 34. One end of the guide tube 34 is connected to a liquid outlet head 35. A fixed disk 32 is fixedly connected to one side of the guide tube 34. An annular electric guide rail 31 is installed on one side of the partition 19. The movable end of the annular electric guide rail 31 is fixedly connected to the fixed disk 32, and the fixed disk 32 and the guide tube 34 are driven to rotate by the annular electric guide rail 31.

[0028] The lower filter mechanism 20 includes a lower filter cartridge 21, a second filter screen 28 and a base frame 24. The lower filter cartridge 21 is threadedly connected to the upper filter cartridge 11, and a sealing ring 22 is fixedly connected to the connection between the lower filter cartridge 21 and the upper filter cartridge 11. The sealing ring 22 is engaged with the upper filter cartridge 11 to enhance the sealing of the connection. A liquid outlet 25 is integrally formed on one side of the lower filter cartridge 21. A second fixing ring 27 is fixedly connected to one side of the lower filter cartridge 21. A second bolt 29 is equidistantly threadedly connected to one side of the second filter screen 28. One end of the second bolt 29 is threadedly connected to the second fixing ring 27. The second filter screen 28 is installed and fixed by the second bolt 29 in cooperation with the second fixing ring 27, which facilitates the disassembly and replacement of the second filter screen 28. A support rod 23 is equidistantly fixedly connected to one side of the base frame 24. One end of the support rod 23 is fixedly connected to the lower filter cartridge 21. The support rod 23 cooperates with the base frame 24 to support the lower filter cartridge 21.

[0029] In one embodiment, in order to prevent the accumulation of dry cells inside the lower filter cartridge 21 from being unable to be discharged, a guide plate 26 is fixedly connected to one side of the interior of the lower filter cartridge 21 .

[0030] In one embodiment, in order to reduce the impact of the external temperature on the interior of the upper filter cartridge 11 and the lower filter cartridge 21 during the filtration process, a thermal insulation interlayer 14 is fixedly connected to the interior of the upper filter cartridge 11 and the lower filter cartridge 21 .

[0032] During operation, the present invention is as follows: stem cells are introduced into the upper filter cartridge 11 through the liquid inlet 12, passing through the first filter screen 16, which filters out larger tissues. The stem cells then pass through the collection portion 33 and enter the guide tube 34. The annular electric guide rail 31 drives the fixed disk 32 to rotate, and the fixed disk 32 drives the guide tube 34 to rotate, so that the guide tube 34 cooperates with the liquid outlet head 35 to distribute the stem cells in a ring shape on the second filter screen 28. After being filtered by the second filter screen 28, the stem cells are guided to the liquid outlet 25 through the guide plate 26 for discharge. After filtration, the upper filter cartridge 11 and the lower filter cartridge 21 are separated, the partition 19 is removed, and the first filter screen 16 and the second filter screen 28 are removed for cleaning.
