Auxiliary equipment capable of achieving self-fastening clamping and automatically reducing speed in case of stall for biological cell separation

Abstract

The invention relates to the technical field of biological cell separation, and discloses auxiliary equipment capable of achieving self-fastening clamping and automatically reducing speed in case of stall for biological cell separation. The auxiliary equipment capable of achieving self-fastening clamping and automatically reducing speed in case of stall for biological cell separation comprises a centrifugal shaft, wherein the outside of the centrifugal shaft is movably connected with a retarding block; the outside of the retarding block is movably connected with a speed reduction plate; the inside of the speed reduction plate is movably connected with a speed reduction magnet; an adjusting spring is movably connected to the top of the speed reduction plate; an electrified coil is movably connected to the top of the adjusting spring; and a piezoresistor is movably connected to the left side of the electrified coil. When the centrifugal shaft stalls too fast, the rotation speed of a cutting coil is increased, the intensity of an induced current is increased, at the moment, electricity flows into the electrified coil through the piezoresistor to generate magnetism, and the electrified coil can generate repulsive force on the speed reduction magnet at the moment so as to stretch an adjusting spring to drive the speed reduction plate to move until the speed reduction plate is in contact with the retarding block, so that the effect of automatic speed reduction if a stall phenomenon occurs in the cell centrifugation process is achieved.

Description

technical field [0001] The invention relates to the technical field of biological cell separation, in particular to an auxiliary device for self-fastening clamping stall and automatic deceleration for biological cell separation. Background technique [0002] With the rapid development of science and technology, it has helped people to study in various fields, and the biological field has always been one of the research fields that people pay close attention to. Through the research on the biological field, people can develop drugs to resist various diseases. Now Now people have developed a variety of vaccines, making people's average life expectancy improved. [0003] In the process of biological research, centrifuges are often used to separate biological cells at differential speeds to obtain different cellular substances. Although traditional centrifuges have stall protection devices, their protection range is relatively large. When the protection device is triggered At t...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an auxiliary device for self-tightening clamping and stalling and automatic deceleration for biological cell separation, which has the ability to automatically decelerate and centrifuge cells if a stall occurs during the centrifugation of cells. The advantage of automatically fastening the test tube during the process solves the problem that when the traditional centrifuge equipment triggers the stall protection mechanism, the equipment has been damaged and cannot be accurately protected, and the test tube is easy to fall off during the centrifugation process.
