[0002] In the field of liquid-based cytology slide preparation, medical centrifuges typically require a rotor carrying the slide preparation unit or slide preparation chamber for centrifugation. Currently, the widely used horizontal rotor system consists of a fixed rotor, a movable basket, and an adapter: the rotor is fixed to the equipment shaft, the basket is suspended from the rotor by hinges, and the slide preparation unit is placed in the adapter within the basket. This structure, composed of fixed and movable parts, is structurally unstable and constrained by the physical space of the basket, making it difficult to meet the demands of high-volume testing.

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0019] The components include: 1. Turntable body; 2. Mounting hole; 3. Limiting hole; 4. L-shaped limiting component; 5. Film maker. Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The purpose of this invention is to provide a rotor for a centrifuge to solve the problems existing in the prior art, making the rotor system structure more stable and enabling a larger number of tests.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] This utility model provides a turntable for a tablet centrifuge, such asFigure 1 As shown, it includes a turntable body 1; wherein an axially penetrating mounting hole 2 is provided at the center of the turntable body 1, and a plurality of limiting holes 3 are evenly distributed along the circumferential direction on the turntable body 1. An L-shaped limiting member 4 is provided on the side of each limiting hole 3 away from the center. The vertical part of the L-shaped limiting member 4 is perpendicular to the upper surface of the turntable body 1, and the horizontal part of the L-shaped limiting member 4 extends directly above the limiting hole 3 and extends towards the center of the turntable body 1.

[0024] In use, the turntable body 1 is installed on the rotor shaft of a centrifuge or liquid-based cell thin-layer slide preparation machine through the mounting holes 2. The slide preparation unit 5 or slide preparation chamber is placed into the limiting holes 3 and fixed in contact with the vertical and horizontal parts of the L-shaped limiting parts 4. Operating parameters such as rotation speed and time are set according to usage requirements, and the centrifugation program is started for slide preparation. The turntable body 1 has no moving parts, resulting in a more stable structure. Furthermore, the absence of a hanging basket allows for higher space utilization, enabling the placement of more slide preparation units 5 or slide preparation chambers, thus increasing the number of slides that can be processed. Simultaneously, the slide preparation units 5 or slide preparation chambers can be installed completely vertically on the turntable body 1 during use, resulting in more uniform slide preparation under centrifugal force.

[0025] As an example of an implementable approach, such as Figure 1 As shown, the number of limiting holes 3 is even. The even number of limiting holes 3 are evenly distributed circumferentially on the turntable body 1, so that each limiting hole 3 has another limiting hole 3 distributed symmetrically with the center of the turntable body 1 as the center, thereby increasing the stability of the rotation of the turntable body 1. In addition, when only one tablet maker 5 or tablet chamber needs to be centrifuged, a counterweight or another tablet maker 5 / tablet chamber can be placed in the other limiting hole 3 at its symmetrical position to ensure that the mass distribution of the turntable body 1 is symmetrical and the operation is more stable.

[0026] As an example of an implementable approach, such as Figure 1 As shown, the limiting holes 3 are distributed in at least two concentric circles along the radial direction of the turntable body 1. The figure shows an example with three circles of limiting holes 3. The multiple circles of limiting holes 3 effectively increase the number of samples that can be detected at one time. Taking a centrifuge chamber device with a diameter of 40 cm as an example, the throughput of the structure in this application is 54 slides, while the throughput of existing technology structures is mostly 12-24 slides. Different circles of limiting holes 3 or corresponding L-shaped limiting parts 4 can be marked with different color marks to prevent the slide maker 5 or slide container from being incorrectly placed in the mismatched circle position. The turntable body 1 can also be designed as a multi-layer structure distributed along the axial direction, with each layer connected in a detachable manner, thereby further increasing the number of slide makers 5 or slide containers that can be accommodated at one time.

[0027] As an example of implementation, the L-shaped limiting member 4 can be detachably connected to the turntable body 1 via bolts. The turntable body 1 is provided with a limiting groove to restrict the rotation of the L-shaped limiting member 4, thus preventing the L-shaped limiting member 4 from rotating. The detachable connection facilitates the switching of different models of L-shaped limiting members 4, increases compatibility with different models of film processors 5 or film preparation chambers, and facilitates the repair and replacement of damaged L-shaped limiting members 4, reducing operating costs. The vertical part of the L-shaped limiting member 4 can also be provided with scale markings to quickly identify whether its specifications match the film processor 5 or film preparation chamber to be placed.

[0028] As an example of implementation, an elastic anti-slip layer can be provided on the bottom surface of the horizontal part of the L-shaped limiting member 4. The elastic anti-slip layer can be made of silicone or polyurethane to facilitate clamping the film maker 5 or the film maker chamber. The L-shaped limiting member 4 can be made of plastic, and the turntable body 1 is made of 316L stainless steel, which has high strength, good corrosion resistance, and is easy to clean and disinfect.

[0029] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
