Flowing type multi-channel biochemical analyzer

Abstract

The invention relates to a flowing type multi-channel biochemical analyzer. The analyzer comprises a sampling needle, a light source, an incident light channel, a detection pool, a photoelectric detector, a computer control system, a distribution valve and a first peristaltic pump, wherein the distribution valve comprises a valve plug, a stepping motor and a valve shell; the valve plug is provided with a first valve plug fluid tube and a second valve plug fluid tube; first valve fluid tubes and second valve fluid tubes are pairwise arranged on the valve shell; when the valve plug is rotated to a specific position, the first valve plug fluid tube and the first valve fluid tubes are communicated inside the valve, and the second valve plug fluid tube and the second valve fluid tubes are communicated inside the valve; and the number of the first valve fluid tubes and the second valve fluid tubes are at least two pairs, each pair of the first valve fluid tube and the second valve fluid tube are respectively connected with the detection pool inlet and the detection pool outlet of a single detection pool. The flowing type multi-channel biochemical analyzer has the advantages of more detection channels, small occupation area, more reasonable flow path and lower instrument cost.

Description

technical field [0001] The invention relates to a multi-channel biochemical analysis instrument in the field of medical clinical testing, in particular to a flow-type multi-channel biochemical analyzer. Background technique [0002] Flow biochemical analyzer is a commonly used detection equipment in the field of clinical detection for the determination of various chemical components in human serum. Most of the semi-automatic biochemical analyzers on the market are single-channel. After selecting the analysis items and analysis methods, the analyzed samples are analyzed one by one. There is no spare detection channel, and the test speed is slow. However, the existing flow-type multi-channel semi-automatic biochemical analyzers generally have the following problems: (1) The flow-distributing device of the existing flow-type four-channel semi-automatic biochemical analyzer generally adopts a five-way shunt with one inlet and four outlets and four sets of The peristaltic pump c...
