automated analyzer for clinical laboratory

摘要

A laboratory automation system (10) that is adapted to carry out clinical chemistry and immunoassay tests, wherein the system comprises: - microwell plates (P) as reaction vessels, - one or more immunoassay processors ( 140, 140a), designed as a magnetic particle processor, located in a first secondary section (66) of an analysis section (60) of the system, wherein the magnetic particle processor includes magnetic rods (162) that are covered with the tips or wraps of combs of disposable tips (164) to move magnetic particles from one microwell to another microwell, where the magnetic particle processor includes magnetic rods (162) that are adapted to move magnetic particles from one microwell to another microwell when covered with the tips or wraps of the disposable tip combs (164), - one or more test processors of clinical chemistry (142) located in a second secondary section (68), different from the first secondary section, of the system analysis section, and - the same aspiration / dosing device (94) for aspirating and dosing liquids for both immunoassays as for clinical chemistry tests, - storage shelves (144) for the microwell plates that are located in or near the second secondary section of the analysis section, - a stack units (146) for the microwell plates for storing the microwell plates for immunoassays and clinical chemistry assays prior to the kit preparation of the microwell plates for immunoassays or clinical chemistry assays, and - an absorbance reader that is integrated into the clinical chemistry assay processor located in the second secondary section of the analysis section to read the clinical chemistry test results from the pl Microwells after processing the reaction mixture, - containers (128) for solid waste and shelves (126) for disposable pipette tips that are located at or near the center of the analysis section (60), - a third secondary section (62) of the analysis section (60) comprising containers for retaining samples and reagents to be used in the tests, cuvettes (116a, 116b, 116c) for containing bulk liquids, such that the Pipette tips (110) can simultaneously aspirate a liquid, - a fourth secondary section (64) of the analysis section (60) comprising a storage area (120) for pipette tips and a plate rotation unit of temperature controllable microwells (122) or stationary suction / dosing locations (124), and shelves (130) for tip combs (164), shelves (132) for used tip combs (164), about shelves (134) pa ra pipette tips, and a shelf stacking unit (136) for disposable tips, - a luminescence reader (150) separated from the immunoassay processor located in the first secondary section (66) of the analysis section to read the results of the immunoassay from the microwell plates after the reaction mixtures have been processed, - an endless belt conveyor (151) to move the microwell plates from the magnetic particle processor to the luminescence reader (150), in where the one or more immunoassay processors are adapted to provide the following functions: incubation of reaction mixtures, mixing of reaction mixtures, separation of components of reaction mixtures, washing of the product or reaction products, and release of a label for enable the reading of immunoassay results, and where the one or more clinical chemistry trial processors are ad suitable for providing the following functions: incubation of reaction mixtures, mixing of reaction mixtures, carrying out a reading with a blank sample, carrying out a reading of a reaction mixture.
