Novel random multi-category full-automatic immunoassay system

Abstract

The invention discloses a novel random multi-category full-automatic immunoassay system. The novel random multi-category full-automatic immunoassay system comprises immunomagnetic beads, reagents and an automatic analyzer. A detection flow adopting the novel random multi-category full-automatic immunoassay system comprises the following steps of putting needed immunomagnetic beads into a reaction cup according to detection categories, adding respectively a sample, reagents and the like into the reaction cup according to a detection program, wherein before addition of each one of the reagents, the immunomagnetic beads and the reaction cup all are cleaned thoroughly, and detecting signals such as light and the like produced immunoconjugates so that a detection purpose is realized. A reaction disk can control a temperature according to detection temperature requirements. During cleaning, the novel random multi-category full-automatic immunoassay system can produce a magnetic field to enable the immunomagnetic beads to suspend or to float up and down, so that good cleaning effects are obtained and a cleaning needle can reach directly and easily to the bottom of the reaction cup to remove residual liquid by suction. After the detection flow is finished, the immunomagnetic beads are taken out by an immunomagnetic beads a removal arm and are abandoned, and the reaction cup is cleaned up and is utilized for the next detection flow. The novel random multi-category full-automatic immunoassay system can push forward immunomagnetic beads or a shakeable reaction disk by a magnetic force to promote full contact between reactants so that reaction sensitivity is improved.

Description

technical field [0001] A random optional multi-item automatic immune analysis system is a fully automatic instrument that can randomly and randomly detect up to dozens of immune test items and complete the measurement, belonging to medical and immunological detection automatic instruments field. Background technique [0002] Immunological detection is very important in disease diagnosis and has been widely used in the diagnosis of infectious diseases, tumors, endocrine and other diseases. In addition, it is also widely used in many fields such as agriculture, pharmaceuticals, food, environment and life sciences. In actual immunological testing, it is often necessary to perform multiple or even dozens of immune items on the same sample. However, the existing fully automated immunoassay has a large and complex design structure, cumbersome operation, few online detection items, and slow speed. Generally, batch detection is performed, and the flexibility of detection items is p...

Problems solved by technology

However, the existing fully automated immunoassay has a large and complex design structure, cumbersome operation, few online detection items, and slow speed. Generally, batch detection is performed, and the flexibility of detection items is poor.

Although there are also immunometers using micro-magnetic beads or plastic balls at present, compared with a random optional multi-item automatic immunoassay system of the present invention: there are different detection processes, it is difficult to expand a large number of online items, and it is inconvenient to store reagents. The problem of consumables / reagents is too much, so there are certain defects
