Full-automatic fluorescence immunoassay analyzer

Abstract

The invention relates to the field of medical instruments, and provides a full-automatic fluorescence immunoassay analyzer. The analyzer comprises a sample adding mechanism, a reagent card bin, a signal acquisition mechanism, a sample feeding mechanism and a buffer liquid bin; the sample feeding mechanism is movably arranged on one side of the reagent card bin, and is used for conveying test tubesplaced on the sample feeding mechanism to a preset position; the reagent card bin is provided with at least one reagent card position, and a scanning window is formed in the position, opposite to a scanning area on a reagent card, of each reagent card position; the signal acquisition mechanism is movably arranged below the reagent card bin so as to obtain the information of the scanning area on the reagent card; the buffer liquid bin is slidably arranged on the other side of the reagent card bin, and the buffer liquid bin is provided with at least one buffer liquid level; and the sample feeding mechanism is movably arranged above the reagent card bin. According to the full-automatic fluorescence immunoassay analyzer, the reagent card bin and the buffer liquid bin are arranged in the analyzer, the automation level of the analyzer is improved, and meanwhile, the testing precision and the testing speed of the analyzer are improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a fully automatic fluorescence immunoassay analyzer. Background technique [0002] Fluorescence immunoassay technology has the advantages of strong specificity, high sensitivity, and good practicability, so it is used to measure biologically active compounds with very low levels, such as proteins (enzymes, receptors, antibodies), hormones (steroids, Thyroid hormones, phthalein hormones), drugs and microorganisms, etc. [0003] When performing fluorescent immunoassay quantitative detection, most of the diagnostic instruments currently on the market are semi-automatic detection instruments, such as the existing fluorescent immunochromatography analyzer NCD-B01 is a semi-automatic detection instrument; its machine structure includes a Advanced optical system and electronic display system, sample addition and chromatographic process are all done manually outside the machine.

AI Technical Summary

Problems solved by technology

[0004] In terms of use, first of all, because the semi-automatic instrument adds samples outdoors, it is very unfavorable for some product inspections that require high temperature; secondly, because manual sampling and sample addition steps are required, and then quantitative analysis is performed by the instrument, the manual labor is increased. The test error caused by the intervention makes the immunochromatography development time and sample addition accuracy inaccurate; and the test speed of the analyzer is slow, and manual sample addition is likely to cause biological contamination

[0005] Finally, most of the existing detection instruments load one sample at a time, and then add another sample to it after the detection is completed

This has caused the following disadvantages: there must be a special manual on duty, repeated operations to load samples, and manual intervention to cause biological contamination; at the same time, the inspectors cannot leave to perform other inspections; in addition, the detection is performed one at a time, which is inefficient and delays the diagnosis of the disease; Secondly, outdoor sampling is not suitable for product testing with high temperature requirements
