Description

Technical Field

[0001] The utility model relates to the technical field of cell separation detection, in particular to a cell separation detection device. Background Art

[0002] Microorganisms are prone to contamination, mutation, and even death during use and propagation, often causing the decline of bacterial strains and potentially the loss of excellent strains. The importance of strain preservation lies in maintaining their original properties and vitality as much as possible, ensuring that the strains do not die, mutate, or become contaminated, so as to facilitate research, exchange, and use. First, excellent pure strains of typical bacterial strains should be selected for preservation. At this time, cell separation detection devices are needed to detect and screen the strains.

[0003] The application number in the existing public technology is: CN202321247111.3 A granulocyte separation and detection device, which is equipped with a hollow cylinder, a first conical circular plate, a second conical circular plate, a limit block, a bar hole, a square ring, a threaded ring, a threaded column, a fixed block and an anti-slip rubber pad, so that the distance between the limit block and the hollow cylinder can be adjusted as needed. At the same time, when the distance between the limit block and the hollow cylinder changes, the limit block allows test tubes of different sizes to be placed in the placement hole, so that test tubes of different sizes can be used on the granulocyte separation and detection device, making the granulocyte separation and detection device more convenient to use.

[0004] However, the above patent still has certain shortcomings in use: although it can achieve the clamping operation of different test tubes by loading and unloading the threaded column and moving the limit block, the frequent rotation of the threaded column not only increases the pulling strength of the personnel but also causes wear of the threaded column and the threaded hole, thereby affecting the subsequent fixation stability. At the same time, although the limit block can abut the surface position of the test tube, the size of the small test tube will be smaller than the size of the placement hole, thereby resulting in a gap on the side of the test tube, which is easy to fall off during subsequent high-speed rotation, resulting in the separation detection being affected. The overall use effect is not very good.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and the advantages of the present invention.

[0029] According to an embodiment of the present utility model, a cell separation detection device is provided.

[0030] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-4 As shown, a cell separation detection device according to an embodiment of the present invention includes a body 1 and a conical circular plate 6. A fixed plate 2 is welded to the middle position inside the body 1. A driving shaft 8 is rotatably connected to the middle position of the surface of the fixed plate 2. A fixed cylinder 9 is fixedly installed at the outer peripheral position of the top of the driving shaft 8. A conical circular plate 6 is fixedly installed on the surface of the fixed cylinder 9. Several groups of adjustment grooves 4 are evenly arranged around the inner position of the conical circular plate 6. An adjustment shaft 12 is rotatably connected to the middle position inside the adjustment groove 4. Several groups of adjustment disks 11 are fixedly installed on the surface of the adjustment disk 11 at the inner position of the adjustment groove 4. Several groups of limit grooves are arranged around the surface of the adjustment disk 11. 14. One end of the adjusting shaft 12 passes through one side of the conical circular plate 6 and is connected to the extrusion spring 7. The outer peripheral position of the top end of the adjusting shaft 12 is slidably connected to the limit plate 10. The top of the limit plate 10 is fixed to the bottom position of the extrusion spring 7, and the top of the extrusion spring 7 is fixed to the top of the adjusting shaft 12. Several groups of limit blocks 5 are installed around the bottom position of the limit plate 10. Several groups of positioning grooves 13 are correspondingly opened on the surface of the conical circular plate 6 below the limit block 5. The positioning groove 13 is provided to fix the limit plate 10 after the adjustment is completed, thereby improving the stability of the limit plate 10 and avoiding the detachment of the test tube 15 due to rotation during use.

[0031] In one embodiment, a motor 17 is fixedly installed at the middle position of the bottom end of the body 1 , and the output end of the top of the motor 17 is connected to the drive shaft 8 .

[0032] In one embodiment, a test tube 15 is clamped inside the limiting groove 14. The test tube 15 is a basic component for cell separation detection, and therefore will not be described in detail.

[0033] In one embodiment, the top of the body 1 is rotatably connected to a cover 3. The cover 3 is provided to shield the periphery of the test tube 15 when it is subjected to high-speed centrifugation, to prevent the invasion of external impurities on the surface, and to prevent the centrifugal effect from being affected.

[0034] In one embodiment, legs 16 are symmetrically installed on both sides of the bottom of the body 1, and the entire device can be fixed by the legs 16 to enhance the stability during use.

[0035] In one embodiment, the size of the limiting groove 14 gradually becomes smaller. The size change of the limiting groove 14 is to accommodate the insertion and use of test tubes 15 of different sizes, thereby expanding the application range of the device.

[0036] In one embodiment, an opening for inserting the test tube 15 is provided on the surface of the conical circular plate 6 , and the provision of the opening facilitates the insertion of the test tube 15 .

[0037] In one embodiment, the opening size, the positioning groove 13 size and the limit block 5 size are all the same as the size of the largest test tube 15. The above-mentioned multiple home structure sizes are set to ensure that the test tube 15 can be inserted, thereby facilitating better subsequent fixed detection.

[0038] Working principle: During actual use, personnel can lift the limiting disk 10 according to the different sizes of the test tubes 15 loaded with cells to be processed, so that the limiting block 5 at the bottom thereof is disengaged from the positioning groove 13, and then personnel can rotate the adjusting shaft 12 to rotate the multiple adjusting disks 11 connected to its surface, thereby causing the limiting grooves 14 of corresponding sizes on the surface of the adjusting disk 11 to move to the opening on the surface of the conical circular plate 6, and then personnel can insert the test tube 15 into the limiting groove 14. Since the size of the limiting groove 14 is adapted to the size of the test tube 15, it can effectively clamp and limit the test tube 15, preventing the test tube 15 from falling off during subsequent high-speed centrifugation, and then After the tube 15 is inserted, the limit plate 10 is lowered again. At this time, the limit block 5 can be reinserted into the positioning groove 13 by squeezing the spring 7, so that the limit block 5 can squeeze the top of the test tube 15. The use of the upper limit groove 14 can achieve multiple limit fixations of the test tube 15, thereby improving the stability of subsequent use. Moreover, during the entire operation process, the personnel only need to lift and rotate, and the effort spent is small, which can effectively reduce labor intensity and avoid better subsequent use. Then, the whole structure can be driven by the motor 17 for high-speed centrifugation, thereby facilitating subsequent detection to obtain the required target cells. The device as a whole has the advantages of convenient fixation, good limiting effect, and labor-saving operation.

For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.
