Abstract

The invention discloses a biomedical homogenization device comprising a rotating assembly and an accommodation component mounted on the rotating assembly. A plurality of accommodation grooves are arranged in the accommodation component, microtubules are arranged in the accommodation grooves, a spiral groove is arranged on the inner wall of each microtubule, a pedestal is slidingly arranged in eachspiral groove, and a magnetic bead is connected on each pedestal through a connecting shaft and is slidingly connected with the corresponding connecting shaft; a plurality of blades are fixed evenlyon the outer side of each magnetic bead; the top and the bottom of each blade are respectively provided with a diversion groove, diversion grooves are connected through diversion holes, and the anglebetween the diversion holes and the diversion grooves is 60 degrees. The deficiency of the prior art can be improved and the processing efficiency of the homogenization device is improved.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to a biomedical uniform device. Background technique [0002] In the field of molecular biology research, it is often necessary to extract the DNA, RNA or protein of various species to be tested or identified in order to carry out subsequent detection and observation of specific factors. Generally speaking, all kinds of tissues (such as skin, liver, kidney, etc.), cells, vaccines and other substances may be mixed with other impurities during the initial treatment, and even cannot be directly used due to the large volume of the tissue. Therefore, it is usually processed in a homogeneous manner, so that it can be applied to subsequent screening or purification procedures. Chinese invention patent CN 103045467 B discloses a biomedical homogenization device, which increases the frequency of repeated collisions of magnetic beads in microtubes by setting a rotating mechanism in two directions....
