A transfer mechanism for the movement of a fluorescent immunoassay quantitative analyzer

Abstract

The invention provides a transfer mechanism for the core of a fluorescent immunoassay quantitative analyzer, which includes a supporting plate, a lower shell is fixedly connected above the supporting plate, a seat plate is connected below the supporting plate, and a front cover and a rear cover are fixedly connected to the upper end of the lower shell Plate, a cavity for detection is provided between the lower shell, the front cover and the rear cover, a rotatable incubation plate is arranged in the cavity, and a first power device for driving the rotation of the incubation plate is arranged on the supporting plate. A fixed carrier is arranged at the center of the fixed carrier, a detection groove is arranged at the middle of the fixed carrier, a measuring head is arranged above the detecting groove, and the measuring head is connected with a second power device that drives it close to or away from the detecting groove. It can not only reduce the material and area of ​​the incubation tray, but also avoid the formation of detection points on the incubation tray, thereby reducing the use of parts and simplifying the overall structure; it completely solves the common problem of poor consistency of instrument channels, and greatly reduces The overall structure is conducive to the use of small and medium-sized hospitals and outpatient clinics.

Description

technical field [0001] The invention relates to fluorescence immunoassay, in particular to a transfer mechanism for the core of a fluorescence immunoassay quantitative analyzer. Background technique [0002] Fluorescence immunoassay analyzes and detects the sample on the reagent strip, and the instrument automatically calculates the content of the analyte in the sample to be tested. The transfer process of the reagent slats in the existing fluorescent immunoassay is as follows: the reagent slats enter the card from the card feeding position, and are transferred to the card slot of the incubation plate through the card feeding mechanism, and the incubation plate rotates to drive the reagent slats to the detection The detection position is formed on the incubation plate, and the positioning mechanism fixes the reagent strips to ensure that the reagent strips for each detection are at the same position, and the measuring head moves to the detection position to detect the reagen...

AI Technical Summary

Problems solved by technology

The overall mechanism is complex, the structure is complex, the transfer path is long, and the formation of the detection position in situ requires the cooperation of the incubation plate, measuring head and positioning mechanism. The overall transfer structure is complex and occupies a large volume, which is not conducive to small and medium-sized hospitals and outpatient clinics.
