TECHNICAL FIELD

[0001] The utility model relates to cell centrifugal equipment technical field, specifically a kind of high-efficiency centrifugal cup. BACKGROUND

[0002] The separation, washing and other of cell need to carry out centrifugal operation, and the centrifugal cup is a commonly used instrument. For example, due to the different physical properties of different cell components, such as density, shape and size, under the action of centrifugal force, the sedimentation rate of different components in the cell is different when the centrifugal cup rotates at high speed, so as to realize separation, such as separating red blood cells, white blood cells and platelets from whole blood.

[0003] During the process of cell centrifugation, different cell components are layered in the centrifugal cup, and it is often necessary to increase the centrifugation time and increase the speed to achieve obvious stratification, which results in low centrifugation efficiency. However, too long centrifugation time and too high speed will cause excessive shear force on the cell components, affecting the cell activity. The separation effect and efficiency of the centrifugal cup are the technical problems that exist universally at present. SUMMARY

[0004] In order to solve the above problems, the utility model provides a kind of high-efficiency centrifugal cup, is provided with guide plate, can be separated to the effect of cell component orientation when centrifuging, improve centrifugation efficiency. The technical scheme adopted by the utility model is as follows:

[0005] A kind of high-efficiency centrifugal cup, including upper cover and lower shell, the upper cover or / and lower shell is equipped with arc guide plate, the curvature of the guide plate is same with the curvature of lower shell side wall, the arc length of the guide plate corresponds to the central angle α, 0 ° < α ≤ 360 °.

[0006] The above-mentioned high-efficiency centrifugal cup, a plurality of filter holes are provided on the guide plate, and the diameter of the filter hole is 0.5-2.0mm.

[0007] The above-mentioned high-efficiency centrifugal cup, the interval between the guide plate and the lower shell side wall is 1.0-2.0mm.

[0008] The above-mentioned high-efficiency centrifugal cup, the height of the guide plate is 0.3-0.8 times the depth of the lower shell.

[0009] The above-mentioned high-efficiency centrifugal cup, 60 ° ≤ α ≤ 360 °.

[0010] The utility model has the beneficial effects that: the guide plate is arranged in the centrifugal cup, which can separate the cells quickly and stratify the cells; further, the filter holes are arranged on the guide plate, which can help the corresponding components of the cells to be filtered out in time and quickly during centrifugation, thereby improving the centrifugation efficiency and separation effect.
