Description

Technical Field

[0001] The invention belongs to the technical field of stem cell processing, and in particular relates to a stem cell filtering separator. Background Art

[0002] With the in-depth development of stem cell and tissue engineering technology research and application, the separation and preparation of stem cells has received increasing attention as one of the key technologies in this field. Generally speaking, stem cells are collected from human or animal placenta, amnion, umbilical cord and other tissues for stem cell separation. However, during the cell separation process, the stem cells need to be filtered.

[0003] When stem cells need to be filtered and separated, a filter membrane is generally used to filter and separate the sample liquid containing stem cells, and larger cells, cell fragments and other impurities are blocked above the filter membrane, thereby achieving filtration and separation of the stem cells. However, in the process of filtering and separating the stem cells, larger cells and cell fragments are easily blocked inside the filter membrane pores, resulting in the filter membrane being unable to effectively filter the stem cells. The existing technology usually uses a scraper to scrape off larger cells and cell fragments accumulated on the surface of the filter membrane to prevent larger cells and cell fragments from clogging the filter membrane surface. However, this treatment method cannot process cells blocked in the filter membrane. Larger cells and cell fragments will still clog the filter membrane pores, resulting in a reduction in the filtration efficiency of the filter membrane for stem cells.

[0022] Specifically, the connecting tube 1213 can be used to draw the larger cells and cell fragments that are blocked inside the pores of the filter membrane 9 into the top of the partition 1212, and the blocked larger cells and cell fragments can be collected, so that the pores of the filter membrane 9 are not blocked by the larger cells and cell fragments, and the method of using a scraper to scrape off the larger cells and cell fragments accumulated on the surface of the filter membrane 9 to prevent the larger cells and cell fragments from being blocked on the surface of the filter membrane 9 is avoided, thereby greatly improving the efficiency and reliability of the device in filtering and separating stem cells.

[0023] In the embodiment, a fifth groove 1410 is formed on the inner wall at the bottom end of the second groove 13, a third electric telescopic rod 1411 is fixedly connected to the inner wall at the bottom end of the fifth groove 1410, a first baffle 1412 is fixedly connected to the telescopic end of the third electric telescopic rod 1411, a sixth groove 1413 is formed on the inner wall at the bottom end of the fourth groove 146, a fourth electric telescopic rod 1414 is fixedly connected to the inner wall at the bottom end of the sixth groove 1413, and a second baffle 1415 is fixedly connected to the telescopic end of the fourth electric telescopic rod 1414.

[0024] Specifically, when the filter membrane 9 is used to filter and separate stem cells, the third electric telescopic rod 1411 and the fourth electric telescopic rod 1414 are controlled to start, and the first baffle 1412 and the second baffle 1415 are used to block the second groove 13 and the fourth groove 146 to prevent the stem cells falling from the surface of the filter membrane 9 from entering the second groove 13 and the fourth groove 146. When the holes of the filter membrane 9 are clogged and need to be processed, the third electric telescopic rod 1411 and the fourth electric telescopic rod 1414 are controlled to return to their original positions, so that the auxiliary frame 148 can be moved to the position corresponding to the fixed frame 8, and the fixed frame 8 can be cooperated with to extract the larger cells and cell fragments in the holes of the filter membrane 9, thereby improving the use effect of the device.

[0025] The operating principle of the present invention is now described as follows: In the present invention, when it is necessary to filter and separate stem cells, the first solenoid valve 5 provided on one side of the liquid inlet pipe 4 is first controlled to open, and then the staff transports the sample solution into the liquid inlet pipe 4. Since only one of the first solenoid valves 5 on both sides of the liquid inlet pipe 4 is opened, the sample solution transported into the liquid inlet pipe 4 will flow into the corresponding separation box 3 through the opened first solenoid valve 5, and then be discharged to the surface of the filter membrane 9. Under the action of gravity, the stem cells in the sample solution will pass through the filter membrane 9 and fall below the filter membrane 9, while the larger cells and cell fragments in the sample solution will remain on the surface of the filter membrane 9, thereby achieving separation and filtration of the stem cells. After the stem cells fall from below the filter membrane 9, they will first fall on the detection plate 105 under the action of gravity. At this time, after the detection plate 105 is subjected to pressure, it will overcome the elastic force of the supporting spring 103 and drive the connecting rod 104 to move downward, thereby compressing the supporting spring 103. At this time, the pressure sensor 102 will detect the pressure, indicating that the corresponding filter membrane 9 holes above the detection plate 105 are not blocked by larger cells and cell fragments. When the larger cells and cell fragments are blocked inside the holes of the filter membrane 9, the corresponding detection plate 105 below the filter membrane 9 at the blocked position will not contact the fallen stem cells. At this time, the corresponding pressure sensor 102 cannot detect the pressure. When half of the pressure sensors 102 do not detect the pressure, it means that the membrane holes at half of the positions of the filter membrane 9 are blocked by larger cells and cell fragments. At this time, the filter membrane 9 needs to be cleaned. In order to not affect the separation and filtration of stem cells when cleaning the filter membrane 9, the first solenoid valve 5 opened previously is closed at this time, and then another first solenoid valve 5 is controlled to be opened, so that the sample solution flows into another separation box 3, and another filter membrane 9 is used to continue to separate and filter the stem cells, and then the first electric slide rail 121 in the separation box 3 used for the first time is controlled to start, drive the first slide plate 122 to move, drive the second electric slide rail 124 to move, so that the two second slide plates 125 are in the same plane with the pressure sensor 102 where no pressure is detected, and then the second electric slide rail 124 is controlled to start, and the two second slide plates 125 are controlled to move, so that the two second slide plates 125 drive the two corresponding fixed frames 8 to move to the filter membrane 9 to be blocked by larger cells and thin cells. The filter element 140 is moved to the position directly above the position blocked by the cell debris, and then the third electric slide rail 141 is controlled to start, so that the third slide plate 142 drives the fourth electric slide rail 144 to move to the position directly below the second electric slide rail 124. Then the fourth electric slide rail 144 is controlled to start, driving the two fourth slide plates 145 to move, so that the two auxiliary frames 148 move to the position directly below the corresponding fixed frame 8. Then the first electric telescopic rod 127 and the second electric telescopic rod 147 are controlled to start at the same time, driving the fixed frame 8 and the auxiliary frame 148 to move toward the filter membrane 9 until the side walls of the fixed frame 8 and the auxiliary frame 148 are in contact with the filter membrane 9. At this time, a relatively closed space is formed between the fixed frame 8, the auxiliary frame 148 and the filter membrane 9. Then the fan 149 and the air pump 129 are controlled to start at the same time.The air pump 129 draws out the air in the space formed by the partition 1212 and the fixed frame 8 through the housing 128 and the exhaust pipe 1211, so that the connecting pipe 1213 draws air into the partition 1212. At this time, the connecting pipe 1213 continuously draws out the air in the space formed by the fixed frame 8 and the filter membrane 9, thereby drawing out the larger cells and cell fragments blocked inside the filter membrane 9, and drawing them to the top of the partition 1212 through the connecting pipe 1213, completing the treatment of the blocked position of the filter membrane 9 hole, and when the fan 149 is started, the fan 149 is turned on. 49 will blow air toward the filter membrane 9, and cooperate with the air extraction of the connecting pipe 1213 to facilitate faster extraction of larger cells and cell fragments in the pores of the filter membrane 9. After the larger cells and cell fragments in the pores of the filter membrane 9 are extracted, the first electric slide rail 121, the second electric slide rail 124, the third electric slide rail 141 and the fourth electric slide rail 144 are controlled to continue to start according to the above steps, and other filter membranes 9 blocked by larger cells and cell fragments are continued to be processed. After the pores of the filter membrane 9 are blocked, another filter membrane 9 is blocked. When the filter membrane 9 in the outer separation box 3 is blocked, the corresponding first solenoid valve 5 is controlled to be closed, and then the first solenoid valve 5 opened for the first time is controlled to be opened again, and the filter membrane 9 that has been blocked is used to continue filtering and separating the stem cells. When filtering and separating the stem cells, the blockage of the filter membrane 9 holes can be detected in real time. When half of the filter membrane 9 holes are blocked by larger cells and cell fragments, the sample solution can flow into another separation box 3 to continue filtering and separating the stem cells to prevent affecting the filtering efficiency of the stem cells. At the same time, the connecting tube 1213 can be used to draw the larger cells and cell fragments blocked inside the filter membrane 9 holes into the partition 1212, and the blocked larger cells and cell fragments are collected, so that the filter membrane 9 holes are not blocked by larger cells and cell fragments, and the method of using a scraper to scrape off the larger cells and cell fragments accumulated on the surface of the filter membrane 9 is avoided to prevent the larger cells and cell fragments from being blocked on the surface of the filter membrane 9, which greatly improves the efficiency and reliability of the device in filtering and separating stem cells.
