[0002] In clinical medicine, biology, immunology and other testing fields, it is often necessary to separate tissue cells by centrifugation. The current common operation is to transfer the tissue cells into centrifuge tubes, then place the centrifuge tubes on the rotor of the centrifuge for fixation, and use the centrifuge to centrifuge the tissue cells.
[0003] Existing technologies include various types of centrifuge equipment capable of performing centrifugation tasks to meet different needs. With the development of cell detection technology, there is currently a significant demand for centrifugation in cell detection. Cell detection requires high detection efficiency and accuracy, but current centrifuge equipment falls short in these aspects.
[0004] For example, Chinese utility model patent application number CN202420742085.X, entitled "A Centrifuge Device for Cell Detection," mainly addresses the problem of an imperfect fixing structure in centrifuge devices, which easily causes test tubes to be thrown out and break. Another example is Chinese utility model patent application number CN202420104922.6, entitled "A Bovine and Sheep Gene Detection Cell Centrifuge," which allows adjustment of the fixing components according to different sample sizes, thus fixing samples of varying sizes and having a wider range of applications. Yet another example is Chinese utility model patent application number CN202323619106.3, entitled "A Low-Speed Centrifuge Rotor with Adapter for Centrifuging Cell Detection Samples," which mainly solves the problem of needing to install numerous conversion modules when operators centrifuge a large number of centrifuge tubes at once.

Detailed Implementation
[0023] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.
[0024] The purpose of this invention is to address the shortcomings of existing technologies by providing a centrifuge for cell detection.
[0025] Example 1
[0026] This embodiment provides a centrifuge for cell detection, referring to... Figures 1-3As shown, the assembly includes: a top cover 1, a housing 2, a centrifuge assembly 6, centrifuge tubes 7, and tube holders 8. The top cover 1 is hinged to the upper rear side of the housing 2. A hydraulic support rod 4 is installed at the rear of the housing 2. The top end of the hydraulic support rod 4 is hinged to the bottom end of the top cover 1 through a support rod hinge seat 5. When the top cover 1 is opened, the hydraulic support rod 4 can support the top cover 1, thereby facilitating the placement of centrifuge tubes 7 onto the tube holders 8. An installation cavity is formed in the center of the housing 2. The centrifuge assembly 6 is installed in the installation cavity in the center of the housing 2. The centrifuge assembly 6 includes a turntable 61. A ring of tube holder slots 611 is arranged at equal angles on the outer ring of the turntable 61. The tube holders 8 can be inserted into the tube holder slots 611. The centrifuge tubes 7 are inserted into the tube holders 8. When the centrifuge tubes 7 inside the tube holders 8 are centrifuged, they can tilt at a certain angle according to the centrifugation rate to improve the centrifugation stratification effect of the cell fluid in the centrifuge tubes 7.
[0027] Reference Figures 1-4 As shown, the centrifugal assembly 6 also includes a turntable base 62, a rotating shaft 63, a motor 64, support rods 65, a motor frame 66, and support rod springs 67. Three support rods 65 are symmetrically arranged at the bottom end of the turntable base 62. The bottom end of the turntable base 62 is connected to the top end of the support rods 65 by the support rod springs 67, which are used to reduce vibration during the movement of the centrifugal assembly 6. The motor 64 is fixed to the center of the turntable base 62 via the motor frame 66, and the rotating shaft 63 is vertically fixed to the drive end of the motor 64.
[0028] Reference Figure 1 , Figure 5 As shown, a placement cylinder 3 is provided in the central mounting cavity of the housing 2, located on the outer ring of the centrifugal assembly 6. The placement cylinder 3 includes a cylinder body 31 and a retaining ring 32. The retaining ring 32 is welded to the bottom inner side of the cylinder body 31. The retaining ring 32 has a shaft hole in the center and protrudes upward in the center. By setting the placement cylinder 3, any solution that accidentally leaks or flows out of the tube can be collected and prevented from flowing to the motor 64 below the placement cylinder 3, thus affecting its normal operation.
[0029] Example 2
[0030] This embodiment provides a centrifuge for cell detection, which is based on the structure in Embodiment 1, and refers to... Figure 6 As shown, the centrifuge tube 7 includes an outer tube body 71, a convex ring 72, and an inner tube body 73. The convex ring 72 is located on the upper outer ring of the outer tube body 71, and the inner tube body 73 is located on the lower inner side of the outer tube body 71. The top of the inner tube body 73 is attached to the inner wall of the outer tube body 71. The inner tube body 73 is conical, which allows the cell fluid in the centrifuge tube 7 to be better separated into layers during centrifugation. The inner tube body 73 is larger at the top and smaller towards the bottom, which makes the solution layering in the lower part of the centrifuge tube 7 more precise and facilitates better collection and separation of the centrifuged liquid after centrifugation.
[0031] Reference Figure 3As shown, the tube seat 8 includes a collar portion 81 and a hook plate 82. The collar portion 81 has a central insertion hole with a diameter larger than the outer diameter of the outer tube body 71 and smaller than the outer diameter of the convex ring 72, so that the centrifuge tube 7 is placed inside the collar portion 81 due to the obstruction of the convex ring 72. The front end of the hook plate 82 is connected to the rear end of the collar portion 81, so that when the centrifuge tube 7 is centrifuged at high speed, it can drive the tube seat 8 to tilt in the tube seat slot 611 and tilt at a certain angle according to the centrifugation rate. The connection between the hook plate 82 and the collar portion 81 is arc-shaped, which facilitates the tilting of the tube seat 8 in the tube seat slot 611.
[0032] This invention relates to a centrifuge for cell detection. In use, the top cover 1 is opened and supported by a hydraulic strut 4, facilitating the placement of centrifuge tubes 7 onto the tube holder 8. The centrifuge tubes 7 containing cell solution are sequentially placed into the tube holder 8, ensuring their symmetrical position on the turntable 61. The top cover 1 is then closed. During centrifugation, the motor 64 drives the turntable 61 to rotate, causing the centrifuge tubes 7 to tilt slightly along with the tube holder 8. As the rotation speed increases, the arc at the connection between the hook plate 82 and the collar 81 can tilt at a greater angle within the tube holder slot 611, improving the centrifugation effect. Because the inner tube body 73 is conical, the cell solution within the centrifuge tubes 7 can better separate into layers during centrifugation, with more precise layering towards the bottom of the tube, facilitating better collection and separation of the centrifuged liquid after centrifugation.
[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
