Medical high-speed centrifugal machine capable of rapidly stopping rotating

Abstract

The invention relates to the technical field of biological medicine, and discloses a medical high-speed centrifugal machine capable of rapidly stopping rotating. The medical high-speed centrifugal machine comprises a base, a centrifugal disc is rotatably connected in the base, a fluid groove is formed in the base and close to the outer side of the centrifugal disc, and an electromagnet I is fixedly connected in the base and close to the outer side of the fluid groove; and three evenly-distributed electroactive polymers are fixedly connected to the interior of the centrifugal disc, and movable grooves are formed in the positions, close to the inner sides of the electroactive polymers, of the interior of the base. According to the medical high-speed centrifugal machine capable of rapidly stopping rotating, through cooperative use of the electromagnet I and magnetorheological fluid, when the centrifugal machine stops power supply and an electromagnet II is powered off, a movable contact block makes contact with a contact sliding block, an electric wire and the electromagnet I are powered on, and therefore the effects that a limiting piece extends outwards, and the magnetorheological fluid is high in viscosity and low in fluidity are achieved; and the purpose of hindering operation of the centrifugal disc is effectively achieved, the effect of rapid stalling of the centrifugal machine is effectively achieved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a medical high-speed centrifuge that realizes rapid stop. Background technique [0002] Biomedical engineering is mainly to understand the structure, function and other life phenomena of the human body at multiple levels in molecules, cells, tissues, organs and even the whole human body system, and to study artificial materials, products, Device and system technology, high-speed centrifuges are used in scientific research, education and production departments such as biology, chemistry, and medicine, and are suitable for rapid separation and synthesis of micro-sample. [0003] High-speed centrifuges usually need to be adjusted to a very high speed to work, which has achieved the centrifugation of drugs, but after the high-speed centrifuge finishes working, the centrifugal disc must be completely stopped before it can be taken out. Because the centrifugal disc rotates too fast...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a medical high-speed centrifuge that realizes rapid stop, which has the advantages of automatic fast stop after centrifugation and improves work efficiency, and solves the problem that the centrifugal disc continues to rotate after centrifugation. It is inconvenient to take out medicines at times, resulting in a decrease in work efficiency
