Problems solved by technology

[0005] However, when the current centrifuge is used, it is necessary to take out the test tube after the sample liquid has been stratified, and then use a straw to take out the supernatant liquid for use. When it is needed urgently, this will reduce the efficiency

Abstract

The invention discloses a centrifugal device for separating and preparing a biological sample, and belongs to the technical field of medical instruments or equipment. The centrifugal device for separating and preparing the biological sample comprises a rotary drum, a test tube, an autorotation module and a revolution module, the tail end of the test tube is flexible and controllable in opening and closing, the test tube is provided with a to-be-separated sample liquid , the tail of the test tube is inserted into a placement hole corresponding to the inner wall of the rotary drum and inclined towards the axis side, the autorotation module controls the test tube to rotate around an axis of the test tube, the tail end is opened, the revolution module controls the test tube to rotate around an axis of the rotary drum, after the test tube rotates, the tail end is opened, the sample liquid integrally descends, the sample liquid is layered after revolution centrifugation, the tail end is closed after rotation is stopped, lower-layer waste residues and upper-layer clear liquid are isolated, and after the test tube is taken out, the clear liquid can be directly used without re-extraction, so that the time is saved, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments or equipment, and more specifically relates to a centrifugal device for separation and preparation of biological samples. Background technique [0002] Hospitals are generally equipped with a centrifuge for separating sample liquid. The centrifuge is a machine that uses centrifugal force to separate components in a mixture of liquid and solid particles or liquid and liquid. [0003] The centrifuge is mainly used to separate the solid particles in the suspension from the liquid, or to separate two different densities and immiscible liquids in the emulsion (such as separating cream from milk). It can also be used to remove liquid from wet solids, such as drying wet clothes with a washing machine; special ultra-speed tube separators can also separate gas mixtures of different densities; Features, some decanter centrifuges can also classify solid particles according to density or particle...
