Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a centrifuge used for cell experiments. Background Art

[0002] Centrifugation technology is one of the most commonly used methods for separating proteins, enzymes, nucleic acids and cell subcomponents. It uses the strong centrifugal force generated by the high-speed rotation of an object to cause the suspended particles placed in the rotating body to settle or float, so that some particles can be concentrated or separated from other particles. Most of the existing centrifuges require experimenters to take the test tube mouth by hand to extract the test tube after centrifugation, which is easy to cause cell fluid contamination in the test tube. For example, a centrifuge for cell experiments recorded in the patent announcement number CN 217411114 U includes a body, a placement tray and a base, the inner bottom wall of the body is installed with a placement tray, the inner wall of the placement tray is provided with multiple groups of embedded holes, the inner wall of the embedded hole is installed with a soft pad, the inner wall of the embedded hole is installed with an air bag, the inner wall of the placement tray is installed with a No. 1 motor, and the bottom of the spring plug is installed with a toothed plate. The above-mentioned comparative documents install an air bag, put the reagent tube into the embedded hole of the placement plate, and the air bag swells, so that the reagent tube is clamped by the soft cushion and the air bag. When rotating the centrifuge, the reagent tube and the placement plate will not shake, making it difficult for the reagent tube to be hit and damaged by the placement plate. However, when extracting the test tube after centrifugation, fingers directly touching the test tube mouth can easily cause contamination of the cell separation solution, resulting in deviations in experimental results.

[0003] Based on this, a centrifuge for cell experiments is now provided, which can effectively reduce the risk of cell fluid contamination caused by contact between fingers and the mouth of the test tube when taking the cell fluid after centrifugation is completed. Utility Model Content

A centrifuge groove 4 is provided at the center of the upper end of the outer shell 1, a centrifuge mechanism 5 is provided at the center of the bottom end of the inner part of the centrifuge groove 4, a plurality of fixed grooves 6 are provided around the bottom end of the inner part of the centrifuge groove 4, a lifting mechanism 7 is provided in the fixed groove 6, and a plurality of suction cups 13 are provided at the outer bottom end of the outer shell 1. When performing cell centrifugation operation, the centrifuge can be fixed on a plane as a whole, which is more stable. A display screen 8 is provided at the upper end of the front outer surface of the outer shell 1, and a user can observe the remaining centrifugation time in real time through the display screen 8. A switch button 9 is provided at the lower end of the front outer surface of the outer shell 1, and an adjusting knob 10 is provided on the left side of the switch button 9. The user can adjust the centrifugation time by rotating the adjusting knob 10 as needed, which is more practical.

[0026] In one embodiment, Figure 2As shown, the centrifugal mechanism 5 includes a motor 51 fixedly connected to the center position of the bottom end of the centrifugal tank 4, a rotating shaft 52 is arranged at the output end of the motor 51, a cross connecting plate 53 is fixedly connected to the upper end of the rotating shaft 52, a placing plate 55 is arranged on the side of the cross connecting plate 53 away from the rotating shaft 32, a limiting groove 54 is arranged at the center position of the mounting surface of the placing plate 55, and the size of the limiting groove 54 is the same as that of the cross connecting plate 53, and a plurality of placing holes 56 are arranged at the upper end of the placing plate 55. When the user needs to centrifuge the cell fluid, the motor 51 is turned on, and the motor 51 drives the cross connecting plate 53 installed above the rotating shaft 52 to rotate, and the cross connecting plate 55 is arranged on the side of the cross connecting plate 53 away from the rotating shaft 32. The connecting plate 53 is inserted into the limiting groove 54, driving the placement plate 55 to rotate together, and the test tube is placed in the placement hole 56. The cell fluid in the test tube successfully completes the separation purpose. A groove 12 is provided on the upper end surface of the outer shell 1. The groove 12 is located on the left and right sides of the upper end of the centrifugal tank 4. A transverse anti-skid groove is provided on the outer surface of the placement plate 55. After the centrifugation is completed, the user can conveniently take out the placement plate 55 together with the test tube for subsequent observation operations to prevent contamination caused by contact with the test tube mouth when taking it. A rubber anti-skid coating is provided inside the placement hole 56 to prevent the test tube from sliding relative to each other during the centrifugation process, thereby causing incomplete centrifugation.

[0027] Example 2

[0028] In one embodiment, Figure 2 and Figure 3 As shown, the lifting mechanism 7 includes a telescopic rod 71 fixedly connected to the center position inside the fixed groove 6, the output end of the telescopic rod 71 is fixedly connected to the surrounding positions of the lower end of the lifting plate 72, and a slot 73 is provided in the middle position of the lifting plate 72. The size of the slot 73 is the same as the size of the motor 51. A plurality of test tube slots 11 are arranged around the upper end of the lifting plate 72. When some cell fluid test tubes in the centrifuge have completed centrifugation, but some test tubes have not completed centrifugation, the telescopic rod 71 is stretched to drive the lifting plate 72 to rise, and the test tubes that have completed centrifugation can be taken out. At this time, the telescopic rod 71 is contracted to drive the lifting plate 72 to descend, and the test tubes that have not completed centrifugation are sent back into the centrifuge to continue the centrifugation operation. Lifting and taking out the test tubes can effectively prevent cell fluid contamination caused by contact with the test tube mouth when taking them out.

[0029] The above embodiment discloses a centrifuge for cell experiments, wherein when the user needs to centrifuge the cell fluid, the suction cup 13 is first used to fix the centrifuge as a whole on a plane, which is more stable, and then the motor 51 is turned on, the motor 51 drives the cross connecting plate 53 installed above the rotating shaft 52 to rotate, the cross connecting plate 53 is inserted into the limiting groove 54, and drives the placement plate 55 to rotate together, and the test tube is placed in the placement hole 56. The cell fluid in the test tube successfully completes the separation purpose, and the groove 12 for convenient finger placement can facilitate the user to place the test tube after the centrifugation is completed. The placement plate 55 is taken out together with the test tube for subsequent observation operations to prevent contamination caused by contact with the test tube mouth when taking it out. When some cell fluid test tubes in the centrifuge have completed centrifugation, but some test tubes have not completed centrifugation, the telescopic rod 71 is stretched to drive the lifting plate 72 to rise, and the test tubes that have completed centrifugation can be taken out. At this time, the telescopic rod 71 is retracted to drive the lifting plate 72 to descend, and the test tubes that have not completed centrifugation are sent back into the centrifuge to continue the centrifugation operation. Lifting the test tube and taking it out can effectively reduce the risk of cell fluid contamination caused by contact with the test tube mouth when taking it out.
