Abstract

The invention discloses a multi-channel parallel pretreatment device, which includes a magnetic separation transfer device and a first driving device; the magnetic separation transfer device includes a second mounting bracket fixedly provided with a syringe cavity, and a mounting plate is provided at the top of the syringe cavity , a plurality of piston rods are arranged on the mounting plate, and the piston rods are movable and sealed with the syringe cavity; a second driving device is also provided on the second mounting bracket; a loading head is arranged on the syringe cavity, and the loading head is a hollow structure; the piston The free end of the rod is provided with a magnetic rod, and the second driving device can drive the magnetic rod on the piston rod to pass through the loading head, and the reciprocating motion of the loading head can be realized by the first driving device and the second driving device, and the mixing of the reaction solution can be completed. Homogenization and resuspension of cleaning solution, simple structure, high reliability, no liquid splash, realizes precise pipetting of samples or reagents, integrates functions of pipetting, magnetic adsorption, transfer, mixing, unloading, etc., greatly improves The degree of product automation.

Description

technical field [0001] The invention relates to the technical field of immunodiagnosis, in particular to a multi-channel parallel pretreatment device. Background technique [0002] The existing detection system based on magnetic particle reaction has become the mainstream methodology of clinical detection due to its advantages of easy automation, fast response speed, and high signal-to-noise ratio, and is widely used in hospitals at all levels. In this type of instrument, the pretreatment system related to the magnetic particle reagent directly affects the stability and accuracy of the equipment test results. [0003] At present, the most widely used conventional magnetic particle chemiluminescence is a large-scale instrument. When performing magnetic separation, the magnetic beads are adsorbed by loading a permanent magnet on the outside of the cuvette. After the adsorption is completed, the waste liquid is sucked away by the suction needle, and then Inject the washing sol...
