By driving the two clamping plates to clamp the sample tube body from both ends, work efficiency can be improved.

Description

Technical Field

[0001] This utility model belongs to the field of structural technology of sample tube fixation components, specifically relating to a sample tube fixation component for a flow cytometer. Background Technology

[0002] Flow cytometry is a device for automated cell analysis and sorting. It can rapidly measure, store, and display a range of important biophysical and biochemical parameters of dispersed cells suspended in a liquid. It can also sort specific cell subpopulations from a pre-selected parameter range. Flow cytometry is used to analyze substances contained within cells collected from the human body, thereby enabling disease screening. Flow cytometry requires the use of a sample tube fixation assembly to analyze cells collected in the sample tube. The sample tube fixation assembly secures the large-diameter, arc-shaped sample tube, facilitating subsequent analysis of the cells by the flow cytometer.

[0003] The sample tube fixation components of existing flow cytometers can shorten the sample tube fixation time and improve the sample tube fixation efficiency, but they require manual adjustment of screws to clamp the sample tubes and cannot automatically fix multiple sample tubes, resulting in low efficiency; moreover, the device cannot be moved during use, affecting the convenience of using the device.

At the same time, it drives the lower clamping plate 34 to move closer to each other along the guide rod 35. In use, the sample tube body 4 is placed between the two clamping slots 36. After the lower clamping plate 34 moves closer, it can clamp the sample tube body 4 in the middle. There are multiple clamping slots 36, so that multiple sample tube bodies 4 can be fixed at one time. The electric push rod 371 raises the upper clamping plate 372 to a certain height, so that the upper clamping plate 372 is located at the bottle mouth position of the sample tube body 4. After the lower clamping plate 34 moves closer to clamp, the upper clamping plate 372 also clamps the sample tube body 4 using the arc groove 373, which improves the stability of clamping.

[0018] Specifically, the internal fixed connection of the arc groove 373 is an anti-slip pad 374.

[0019] By adopting the above technical solution, the anti-slip pad 374 can be made of rubber, which can increase the friction between the clamp and the sample tube body 4.

After the lower clamping plates 34 move closer together, they can clamp the middle sample tube body 4. There are multiple clamping slots 36, which can fix multiple sample tube bodies 4 at one time. The electric push rod... The rod 371 raises the upper clamping plate 372 to a certain height, so that the upper clamping plate 372 is located at the bottle mouth of the sample tube body 4. After the lower clamping plate 34 comes together to clamp, the upper clamping plate 372 also clamps the sample tube body 4 using the arc groove 373, which improves the stability of clamping. The anti-slip pad 374 can be made of rubber, which can increase the friction between the clamping plate and the sample tube body 4. The sponge block 38 can provide cushioning for the sample tube body 4 to prevent the sample tube body 4 from being broken. By driving the two clamping plates to clamp the sample tube body 4 from the upper and lower ends, the work efficiency can be improved.

[0025] By adopting the above technical solution, the hydraulic cylinder 53 drives the fixing plate 54 to press against the ground, which can fix the device.

[0026] Specifically, a connecting rod 55 is fixedly connected to the side of the support plate 51 away from the hydraulic cylinder 53.

[0027] By adopting the above technical solution, the connecting rod 55 connects the two support plates 51 to each other, improving the stability of the support, and at the same time, items can be temporarily placed on the connecting rod 55.

[0028] In this embodiment, the top of the support plate 51 is connected to the machine base 1, and the machine base 1 is moved freely by the moving wheels 52.
