Abstract

The invention discloses a multi-channel parallel pretreatment device. The multi-channel parallel pretreatment device comprises a magnetic separation transfer device and a first driving device; the magnetic separation transfer device comprises a second mounting bracket fixedly provided with an injector cavity, a mounting plate is arranged at the top of the injector cavity, a plurality of piston rods are arranged on the mounting plate, and the piston rods are movably and hermetically connected with the injector cavity; a second driving device is further arranged on the second mounting bracket; a loading head is arranged on the injector cavity and is of a hollow structure; a magnetic bar is arranged at the free end of the piston rod, the second driving device can drive the magnetic bar on the piston rod to penetrate through the loading head, reciprocating motion of the loading head is achieved through the first driving device and the second driving device, uniform mixing of reaction liquid and resuspension of cleaning liquid can be completed, the structure is simple, reliability is high, and liquid splashing is avoided. Accurate pipetting of a sample or a reagent is achieved, the functions of pipetting, magnetic adsorption, transferring, uniform mixing, unloading and the like are integrated, and the automation degree of the product is greatly improved.

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...
