Automatic sampling mechanism of analytical instrument

Abstract

The invention provides an automatic sampling mechanism of an analytical instrument, comprising a rack; the rack is provided with a first stepped motor, a pipette drive device and a liquid collecting box, wherein, the output shaft of the first stepped motor is provided with a rotary table; a plurality of test tube fixing holes are evenly arranged on the edge of the rotary table; the pipette drive device is provided with a pipette which is connected with a liquid sucking pump through a conduit; the liquid collecting box is provided with a detection cup transmission device which is provided with a plurality of detection cups; a reagent filling tube and a measuring electrode are arranged above the liquid collecting box; the reagent filling tube is connected with a reagent container through a liquid adding pump; and the bottom of the liquid collecting box is provided with a water outlet which is connected with a waste liquor collecting tank through a pipeline. The automatic sampling mechanism provided by the invention has the advantages of high operation precision, rapid sampling speed, simple structure and low cost.

Description

Technical field [0001] The invention relates to an automatic analysis instrument, in particular to an automatic sampling mechanism of the analysis instrument. Background technique [0002] At present, most of the sampling mechanisms used in various medical analyzers, such as trace element analyzers, biochemical analyzers, etc., rely on imports. These imported sampling mechanisms have high operating accuracy and fast sampling speed, but their structure is more complex, and the price and maintenance costs are relatively high. However, most of the domestic sampling institutions have the defects of low operating accuracy and slow sampling speed due to their own design defects. So far there is no domestic automatic sampling mechanism on the market that can completely replace imported products. Summary of the invention [0003] The purpose of the present invention is to provide an automatic sampling mechanism of an analytical instrument, which has high operating accuracy, fast sampling ...
