Reagent disk

Abstract

The invention provides a reagent disk comprising a substrate, a first rotating shaft rotatablely arranged on the substrate, a reagent rack assembly used for placing a reagent bottle, and a driving element used for driving the first rotating shaft to rotate, wherein the reagent rack assembly comprises a connecting shaft connected with the first rotating shaft. According to the reagent disk provided by the invention, the driving element is used for providing motive power to drive the first rotating shaft and the reagent rack assembly to rotate so as to uniformly mix magnetic bead reagents while placing the reagents; since the uniformly mixed reagent is directly selected in the reagent bottle when needing to select the reagent to perform experimental analysis, the magnetic bead reagents liable to generate settlement are not specially mixed, thereby omitting the time of singly performing the uniform mixing operation, and further shortening the time sequence period of the whole system and improving the integral efficiency of a full-automatic instrument. Moreover, no object directly touches the reagent in the reagent bottle in a working process of the reagent disk, thereby reducing the cleaning liquid consumption and completely eliminating the cross contamination of different reagents.

Description

technical field [0001] The invention relates to the technical field of chemiluminescence detection and analysis, and more specifically relates to a reagent disc. Background technique [0002] Magnetic particle biotin amplification type automatic chemiluminescence analyzer needs to use magnetic bead turbidity solution, enzyme, biotin and other reagents during the test process. At present, the above reagents are often placed on the reagent plate, and then selected according to different test items. Pipette the various reagents needed in the reagent tray. However, the magnetic bead turbid solution reagent is determined by its physical characteristics, and it is easy to precipitate once it is left standing; if the magnetic bead reagent precipitates and then participates in related reactions, it will seriously affect the stability and reliability of the test results; therefore, when using magnetic beads Reagents need to be mixed before use. [0003] For magnetic bead reagents, ...

AI Technical Summary

Problems solved by technology

This method can avoid the problems of cross-contamination and consumption of cleaning solution caused by method one; however, because the suction and puff action generated by the pipetting device is used for mixing, the mixing time is long and the automation speed is low; In the process of taking the reagent, the magnetic bead reagent is specially mixed, which increases the time for the separate mixing operation, which in turn increases the timing cycle of the entire system, resulting in low overall efficiency of the fully automatic instrument
