Multi-reagent needle biochemistry analyzer

Abstract

The invention provides a multi-reagent needle biochemistry analyzer provided with a precision reagent pump and array reagent needles connected with the precision reagent pump. The multi-reagent needle biochemistry analyzer comprises a sample storage tray, a reaction tray, a sampling mechanical arm for adding a sample and a plurality of cuvettes arranged in the reaction tray as well as a reagent adding system for adding a reagent into the cuvettes. The multi-reagent needle biochemistry analyzer is characterized in that the reagent adding system comprises more than two agent bottles, more than two precision agent pumps and the array agent needles, wherein the array reagent needles comprise more than two agent needle units; a single reagent bottle is communicated with the input end of a single precision reagent pump; and the output end of the single precision reagent pump is communicated with a single reagent needle unit. With a plurality of reagent needle units, the speed of adding reagents into the cuvettes can be improved and the detection efficiency of the whole analyzer can be improved; and the cuvettes are changed into disposable cuvettes, so that the inaccuracy of experimentaldata caused by the long-term use of the cuvettes can be effectively avoided.

Description

technical field [0001] The invention relates to a multi-reagent needle biochemical analyzer, more specifically, to a multi-reagent needle biochemical analyzer equipped with a precision reagent pump and an array of reagent needles connected thereto. Background technique [0002] Biochemical Analyzer is a clinical routine analysis instrument in hospitals, mainly used to measure various biochemical indicators in human body fluids, including blood routine, myocardial enzyme spectrum, blood sugar and blood lipids, liver function, immunoglobulin and other routine biochemical indicators. At present, the existing automatic biochemical analyzer is mainly composed of a sample device, a reagent device, a sampling device, a reaction pool, an incubator, a detector, a microprocessor, a printer, a functional detector and the like. But existing full-automatic biochemical analyzer has more shortcoming, one is, in the operation process of existing biochemical analyzer, the reaction plate rota...

Problems solved by technology

But existing full-automatic biochemical analyzer has more shortcoming, the one, existing biochemical analyzer is in operation process, and reaction plate rotates one circle, can only add a kind of reagent and sample, makes its testing speed like this It is not high, especially when there are many data to be detected, it cannot meet the requirements; the second is that the cuvettes on the existing biochemical analyzers are recycled, and when they are recycled, they are easy to cause cross-contamination due to unclean cleaning, and The cuvette will cause a certain degree of wear and tear during long-term use, which makes its light transmittance poor. Cross-contamination and wear can lead to a large difference between the measured experimental data and the actual data
