Problems solved by technology

From the point of view of the entire sampling process, the instrument saves the reagent temperature rise time between the addition of the first reagent and the addition of the sample, so it cannot guarantee that the biochemical project will strictly implement the insulation reaction according to the specific reaction temperature (37°C), which will inevitably affect the reaction. Effects and Test Accuracy
In addition, the instrument cancels the independent stirring mechanism, relying on the positive pressure to spray the mixed solution when adding the sample, which cannot achieve the ideal mixing effect

Embodiment Construction

[0067] The device and method of the present invention will be described in further detail below in conjunction with the accompanying drawings and the embodiments shown in the accompanying drawings.

[0068] A specific embodiment of the complete machine structure of the discrete multi-channel full-automatic biochemical analyzer of the present invention is shown in Fig. 1 and Fig. 2, including:

[0069] A reaction disk assembly 1 includes: a turntable 14 and a first rotary drive mechanism for driving the turntable 14 to rotate. The turntable 14 is arranged with cuvettes 11 in a certain order along the circumference, that is, a total of 80 cuvettes are arranged at equal intervals along the circumference of the turntable 14. A disposable reaction cup 11, the reaction cup 11 relies on its own positioning hole 28 to engage with the positioning pin shaft 29 (Figure 4) on the reaction plate to achieve circumferential positioning, and is convenient for manual loading and unloading of th...

Abstract

This invention relates to composite multiple channel total automatic biological analyzers, which comprises reaction disc element, sample and agent memory disc elements, sample in element and mixture bar element. The invention can use one piece of liquid drawing probe for adding agent and sample, wherein, the fix probe mechanic arm is set with heating block to draw probe agent for pre-heating to achieve best reaction temperature as human once reaction cup.

Description

technical field [0001] The present invention relates to methods and devices for chemically testing and analyzing biological materials. Background technique [0002] Discrete automatic biochemical analyzer is currently the most widely used type of biochemical analysis product. This type of instrument is mainly composed of reaction tray (including constant temperature system), sample tray (or sample track), reagent tray, sample dispensing mechanism, reagent It consists of dispensing mechanism, stirring mechanism, cuvette cleaning device and user operating system. In discrete biochemical analyzers with a relatively simple structure, the sample tray and the reagent tray are often combined into one, and a probe is used for filling both the reagent and the sample, such as patents US5051238 and US5314825. In the device corresponding to the patent US5051238, the sample tray and the reagent tray are in a coaxial structure, and the reagent tray is located on the outer ring of the sam...
