Abstract

The invention discloses an automatic biochemical analyzer and an analyzing method. The analyzer mainly structurally comprises a reagent disc, a reaction disc, a sample disc, a stirring unit, an optical detection unit, a control unit, a reagent needle, a sample needle and more than one reagent suction and diluting device; the analyzer has a function of automatically diluting the reagent gradually before the reagent is utilized; the effects of reducing the volume of the reagent and reducing the contact area between the analyzer and the inner part of the reagent needle are realized and the washing difficulty of residual reagents in the reagent needle is reduced; residues in the reagent needle are few so that crossed contamination can be reduced; the analyzer is further provided with a sample diluting unit; the sample is diluted to reduce the viscosity; sample suction errors are reduced, the sampling precision and detection precision are improved, and the sample needle is also convenient to wash. According to the automatic biochemical analyzer and the analyzing method, production, storage, transportation and dosage of the reagent are greatly reduced; the economical efficiency of a detection system is improved; meanwhile, the crossed contamination is reduced and the detection accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of medical inspection and detection, and in particular relates to a fully automatic biochemical analyzer and a method. [0002] technical background [0003] Existing automatic biochemical analyzers for medical testing generally use shared reagent needles and shared sample needles to draw, reagents and samples, and even some automatic biochemical analyzers have only one needle for both drawing reagents and taking samples. sample. In order to eliminate the cross-contamination between different reagents, a cleaning will be performed after each reagent and sample is drawn, and then the reagent of the next item or the next different sample will be drawn immediately. Since there is often some residual liquid on the inner wall of the needle after drawing reagents, samples, and cleaning, if the residual liquid on the inner wall of the needle cannot be effectively removed, some residual reagents and samples will oft...
