Description

Technical Field

[0001] The utility model relates to the technical field of culture fluid aspirating equipment, in particular to a culture fluid aspirating device for biological cell culture. Background Art

[0002] Cell culture refers to a method of simulating the in vivo environment (sterility, suitable temperature, pH and certain nutritional conditions, etc.) in vitro to enable cells to survive, grow, reproduce and maintain their main structures and functions. The cell culture plate is one of the cell culture devices. In the prior art, the culture fluid suction device drips the culture fluid into the culture wells of the cell culture plate. When adjusting according to the size of the culture plate, the splicing between multiple suction tubes lacks uniform guidance, resulting in uneven installation between multiple suction tubes. When suction is used, the bottom of the suction tube is not on the same horizontal line, and there is a lack of convenience for automatic height adjustment of the suction equipment.

[0003] For example, the authorized patent document with application number 202020183869.5 discloses a culture fluid suction device for biological cell culture, including a compressed air bag, a trachea is fixedly installed in the middle position of the lower end surface of the compressed air bag, a connecting block B is fixedly installed in the middle position of the lower end surface of the trachea, grooves are arranged on both sides of the interior of the connecting block B, connecting plates are arranged on both sides of the connecting block B, the other end of the connecting plate is slidably connected to a connecting block C, grooves are arranged on both sides of the interior of the connecting block C, connecting plates are arranged on both sides of the connecting block C, the other end of the connecting plate is slidably connected to a connecting block A, a groove is arranged on one side of the interior of the connecting block A, and a suction pipe is fixedly installed in the middle position of the lower end surface of the connecting block A, the connecting block B and the connecting block C. The utility model can control the amount of culture fluid sucked, and can be applied to culture plates of different sizes, which increases the applicability of the device.

[0004] The above patent has the problem that the joints between the multiple suction tubes lack uniform guidance, resulting in uneven installation between the multiple suction tubes. When used for suction, the bottoms of the suction tubes are not on the same horizontal line. At the same time, there is a lack of automatic height adjustment for the suction equipment. Therefore, we need to provide a culture medium suction device for biological cell culture. Utility Model Content

[0029] A mounting mechanism 8 for splicing a plurality of movable tubes 6 is installed inside the mounting seat 4;

[0030] The mounting mechanism 8 comprises a mounting groove 81, an insert plate 82, a thin tube 83, a limiting ring 84, a thick tube 85 and a sealing cover 86. Two insert plates 82 are fixedly mounted on the surface of the movable tube 6. A mounting groove 81 for sliding the insert plates 82 is provided inside the mounting seat 4. One side of the movable tube 6 is connected with the thin tube 83, and the other side of the movable tube 6 is connected with the thick tube 85. The surface of the thin tube 83 is fitted with a limiting ring 84, and the surface of the limiting ring 84 is fitted with one side of the thick tube 85. A sealing cover 86 is threadedly mounted on one side of the thick tube 85.

[0031] One side of the lifting seat 2 is connected to the mounting seat 4 through an assembly mechanism 9.

One side of the mounting seat 4 is fixedly provided with an assembly strip 92, and the surface of the assembly strip 92 is engaged with the inside of the assembly groove 91. One side of the lifting seat 2 is threadedly provided with a limit screw 93, and one end of the limit screw 93 is in contact with the surface of the assembly strip 92.

[0032] In this embodiment, the corresponding suction tubes are assembled according to the number of grooves carrying cell fluid on the culture dish, and the plug plate 82 on the surface of the movable tube 6 is inserted into the mounting groove 81 in the mounting seat 4 and slides, so that the thin tube 83 on the surface of the movable tube 6 is inserted into the thick tube 85 on the surface of the fixed tube 5, and at the same time, the plug plate 82 on the surface of another movable tube 6 is inserted into the mounting groove 81 and slides, and the above thick tube 85 is inserted into the thin tube 83 repeatedly, and the inner wall of the thick tube 85 is tightly fitted with the surface of the thin tube 83 to achieve a sealing effect. After multiple movable tubes 6 are assembled, the thick tube 85 on the surface of the last movable tube 6 is sealed with a sealing cover 86. When the air pump 7 is started, since multiple movable tubes 6 are connected to the fixed tube 5, the gas in the fixed tube 5 is extracted, and the gas in other movable tubes 6 is extracted to achieve the suction operation. When the entire mounting seat 4 is disassembled and cleaned, the rotating limit screw 93 is not fitted with the assembly strip 92, so that the assembly strip 92 can be separated from the assembly groove 91, and the entire mounting seat 4 can be completely removed.
