Description

Technical Field

[0001] The utility model relates to a centrifugal tray for cell slice making clamps, belonging to the technical field of medical equipment. Background Art

[0002] Cell slide holders are widely used testing equipment in medical testing, generally consisting of a slide chamber, a slide and a base. Most existing cell slides are made by cell slide machines instead of manual slides, and a centrifuge is essential for centrifuging the cell slide holders.

[0003] The centrifugal discs used in existing cell preparation clamp centrifugation are mostly solid discs with heavy weight, and the centrifugal speed cannot be effectively increased. Therefore, the applicant designed a centrifugal disc with a stable structure and light weight, which can increase the centrifugal speed to ensure the stability of movement. However, in actual use, it was found that after the rotation speed of the centrifugal disc was increased, when the centrifugal speed was too high, the cell preparation clamps carried by the tray would swing randomly at the beginning of the centrifugation, and during the high-speed centrifugation, the cell fluid in the cell preparation chamber would splash, causing cell sample contamination.

[0004] Therefore, the centrifuge tray needs to be redesigned to be suitable for high-speed centrifugation processes. Utility Model Content

[0005] The utility model aims to make up for the deficiency of new technology in practical application and provide a centrifugal tray for cell preparation clamps which can ensure the stability of centrifugal operation and prevent the cell fluid in the preparation chamber from splashing out during the centrifugation process.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0007] A centrifugal tray for cell preparation clamps comprises a tray body which is mounted on a centrifugal tray and can swing, and is characterized in that a counterweight block is arranged at the bottom of the tray body.

[0008] The centrifugal tray for cell slice preparation as described above is characterized in that the counterweight block is detachable.

[0009] The centrifugal tray for cell slice preparation as described above is characterized in that the counterweight block is arranged at the center of the tray body.

[0010] The centrifugal tray for cell preparation clamp as described above is characterized in that the counterweight block weighs 20-100g.

[0011] The centrifugal tray for cell preparation clamps as described above is characterized in that the tray body is provided with two base compartments for placing the cell preparation clamps, a counterweight block connecting groove is provided between the two base compartments, and the counterweight block is connected to the counterweight block connecting groove.

[0012] The centrifugal tray for cell slice preparation as described above is characterized in that the counterweight block is connected to the center of the tray body by screws.

[0013] The centrifugal tray for cell preparation clamp as described above is characterized in that the counterweight block is in the shape of a weight.

[0014] The centrifugal tray for cell slice preparation clamps as described above is characterized in that both sides of the tray body are provided with ear grooves connected to the centrifugal tray, and anti-detachment ribs are designed in the ear grooves to prevent the tray body from detaching from the centrifugal tray.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] The utility model arranges a counterweight at the bottom of the centrifugal tray. When the cell preparation clamp is placed statically, the tray is not easy to shake out the cell fluid in the preparation chamber. During the centrifugation process, the tray can be quickly balanced under the action of the counterweight, so as to maintain the movement stability of the tray and prevent the cell fluid from splashing out and causing cross contamination of samples during high-speed centrifugation.

[0017] The utility model has a simple structure, but effectively ensures the movement stability of the cell preparation clamp in high-speed centrifugation, and effectively solves the defect of sample splashing when the centrifugation speed is increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described in detail below in conjunction with specific embodiments:

[0023] like Figure 1-4As shown, a centrifugal tray for cell preparation clamps includes a tray body 1 installed on a centrifugal disk 100 and capable of swinging, and a counterweight block 2 is provided at the bottom of the tray body 1. The cell preparation clamp includes a preparation chamber 4, a slide 5 and a base 6. When the centrifugal disk 100 is stationary to place the cell preparation clamp, the centrifugal tray will not swing significantly due to the gravity of the counterweight block 2, ensuring that the cell fluid in the preparation chamber 4 will not overflow due to shaking; at the beginning of centrifugation, the counterweight block 2 is subjected to the gravity and centrifugal force, so that the centrifugal tray on the centrifugal disk 100 maintains the same tilt direction, preventing the samples in the preparation chamber 4 from splashing and cross-contaminating each other; during high-speed centrifugation, the counterweight block 2 makes the tray body 1 have a certain weight, and the movement is stable during the centrifugation process to prevent the sample from splashing.

[0024] The counterweight 2 is detachable, which is convenient for disassembly, cleaning and disinfection, and is also convenient for replacing counterweights 2 of different weights to meet different centrifugal speed requirements. The weight of the counterweight 2 is 20-100g, preferably 20-50g, and more preferably 25-40g. The disc body 1 and the counterweight 2 preferably weigh 50-110g together. Ensure that the liquid in the film making chamber 4 is balanced and stable during centrifugal movement without splashing, and at the same time minimize the impact on the centrifugal speed of the centrifuge.

[0025] Preferably, the counterweight 2 is disposed at the center of the disc body 1, which can quickly keep the disc body 1 balanced during centrifugal motion.

[0026] Further, the disc body 1 is provided with two base compartments 11 for placing the cell preparation clips, a counterweight block connection slot 12 is provided between the two base compartments 11, and the counterweight block 2 is connected to the counterweight block connection slot 12. The counterweight block 2 can be snapped onto the disc body 1, and preferably the counterweight block 2 is connected to the center of the disc body 1 by a screw 3. More preferably, the counterweight block 2 is in the shape of a weight, which is conducive to maintaining the centrifugal motion balance of the disc body 1.

[0027] In a specific embodiment of the utility model, the disc body 1 is provided with a hanging ear groove 13 connected to the centrifugal disc 100 on both sides, and the hanging ear groove 13 is designed with an anti-slip rib 14 to prevent the disc body 1 from being separated from the centrifugal disc 100. It ensures that the disc body 1 can swing freely and maintain balance during the high-speed movement of the centrifugal disc 100, and also prevents the disc body 1 from falling out during high-speed centrifugation, affecting the operation of the entire centrifuge.

[0028] In a centrifuge for cell preparation, multiple cell preparation clips can be placed on the centrifugal disk 100 for centrifugation at one time. Multiple centrifugal trays are arranged on the centrifugal disk 100. A counterweight block is arranged at the bottom of the disk body 1 of the utility model, which is conducive to increasing the centrifugal speed while ensuring the stability of the centrifugal motion; at the same time, two preparation clips can be placed on one disk body 1, saving the physical structure of the centrifugal disk 100, and more preparation clips can be centrifuged at the same time, thereby improving the preparation efficiency.
