Protective biological cell separation and rotation equipment with self-locking function

Abstract

The invention relates to the technical field of cell separation equipment, in particular to protective biological cell separation and rotation equipment with a self-locking function. The equipment comprises an equipment main body, a positioning frame is fixedly connected to the interior of the equipment main body, a driving shaft is inserted into the position, located in the center of the interiorof the equipment main body, in the positioning frame, an electromagnet is fixedly connected to the lower surface of the positioning frame, a fixed frame is fixedly connected to the lower surface of the electromagnet, a movable plate is inserted into the lower surface of the fixed frame, a limiting plate is clamped with a convex tooth block on the outer surface of the driving shaft, so that the driving shaft is locked, therefore, the problem of overlarge centrifugal force possibly caused by a stall phenomenon is prevented, the correctness of cell tissue sample data is ensured, high-load operation of the equipment is avoided, the rotating shaft in the equipment is protected by extruding and discharging protection liquid inside a plastic air cushion, so that accelerated aging of the rotatingshaft due to long-time operation is avoided, and therefore, the service life of the equipment can be well prolonged.

Description

technical field [0001] The invention relates to the technical field of cell separation equipment, in particular to a protective type biological cell separation rotating equipment with self-locking function. Background technique [0002] Cell separation techniques include centrifugation, flow cytometry, and cell electrophoresis. Centrifugation is the basic method for studying such as nucleus, mitochondria, Golgi body, lysosome and microbody, as well as various macromolecules. Before the study of biological cells, it needs to be separated from the sample, because the cell has a variety of substances. , the composition is relatively complex, so it is often necessary to centrifuge the cell extract with the help of a centrifuge to obtain the desired cell tissue and sample. [0003] However, due to mechanical or procedural failure of existing equipment, runaway centrifuge speed may occur. When the centrifugation speed is too fast, the centrifugal force will increase accordingly,...

Problems solved by technology

[0003] However, due to mechanical or procedural failure of existing equipment, uncontrolled centrifuge speed may occur

When the centrifugation speed is too fast, the centrifugal force will increase accordingly, which may cause irreversible damage to the cell tissue, resulting in the failure of the data of the cell tissue sample, and the high-speed rotation of the device will cause a high load on the shaft of the device. Thereby the service life of equipment may be reduced; therefore, those skilled in the art provide a kind of protective type biological cell separation rotating equipment with self-locking effect, to solve the problems raised in the above-mentioned background technology
