Abstract

The invention belongs to the technical field of medical detection devices, and in particular relates to a magnetic particle cleaning device; it includes a mounting frame, a rotating shaft that can move up and down is vertically installed in the mounting frame, and a horizontal swing arm is fixedly connected to the upper end of the rotating shaft. A cleaning head is installed at the front end of the arm, and multiple groups of cleaning needles are installed at the lower end of the cleaning head; a cleaning component is also installed in the installation frame, and the cleaning component is fixedly installed under the cleaning head. The cleaning component includes a reaction unit, a vibration cavity, a ring electromagnetic Iron and excitation source; the reaction unit is equipped with multiple reaction positions corresponding to the cleaning needles one by one. The reaction unit is placed in the vibration chamber and the two are detachably connected. Tightly sleeved outside the vibration chamber, the excitation source is installed below the vibration chamber and the two are in contact; the present invention aims to provide a magnetic particle cleaning device, which overcomes the cumbersome operation and relatively slow cleaning speed of the existing magnetic particle cleaning device. slow problem.

Description

technical field [0001] The invention belongs to the technical field of medical detection devices, in particular to a magnetic particle cleaning device. Background technique [0002] Chemiluminescent immunoassay instruments generally use magnetic particles as reaction carriers. In the immune reaction, the bound substances produced by the reaction between the sample and the reagent are attached to the magnetic particles, and the unbound substances are free in the liquid. Through the action of an external magnetic field, the unbound substances are washed and removed, and the bound substances are retained. It has sensitivity and detection It has the advantages of fast speed and good repeatability. [0003] The existing magnetic particle cleaning device has a low degree of automation, the position of the cleaning head is fixed, and only one cuvette can be cleaned at a time. The operation is cumbersome, and the cleaning process takes a relatively large amount of time in the whole...
