Introduction to the Main Structure and Detection Principles of Fully Automated Biochemical Analyzers

The fully automated biochemical analyzer is a smart photoelectric medical instrument that integrates light, machine, electricity, calculation, and biochemistry analysis technology. It can be roughly divided into four parts, including sampling systems, optical systems, control systems and data processing systems. The input system is the premise of analysis. The optical system is the core of the entire instrument. The control system is the guarantee of the analysis. The data processing system is a function expansion.

The basic working principle of the fully automated biochemical analyzer is to illuminate the color liquid in the container of the monochrome beam. By the absorption of light energy by the sample measurement, the light signal is converted to the corresponding electrical signal from the detector (photoelectric converter) This signal is large, rectified, and converted into a digital signal, sent to the computer, and the computer controls the driving power driver filter wheel and sample disk. Save, printers printed the corresponding results at the same time. After ZUI, the container was cleaned after each group of samples was measured.

So, what are the main structures of the fully automated biochemical analyzer?

1. Sample device: Place the samples, standard products, quality control fluids, blank liquids and control fluids.

2. Sampling device: include diluers, sampling probes and pipelines of conveying samples and reagents.

3. Reaction tank or reaction channel: The role of color dishes (tube) is generally raised.

4. Insulation: Provide constant temperature for chemical reactions.

5. Detector: such as color meter, optical light meter, fluorescent lighting meter, flame light meter, electrochemical measurement meter, etc. Different instruments configuration is different.

6. Micro -processor: The computer part of the analyzer, also known as the program controller. Control all the movements and functions of the instrument. Users can "dialog" through the keyboard and the instrument. At the same time, the computer can also accept signals feedback from each component, and make corresponding reactions to send a certain indication signal to the abnormal situation. Analysis software and analysis results generally store in disks for inquiries.

7, printer: can draw reaction dynamic curves and print inspection reports.

8. Function monitor: The display is part of it. You can view the situation of the reaction state, the "dialogue" of the human -machine, the current instrument working status, and the analysis results.

The fully automatic biochemical analyzer is a medical optical analysis instrument that is determined by body fluids, clinically fast testing blood routine, myocardial enzyme spectrum, blood sugar and blood lipids, and liver function. One of the large instruments. It is widely used in clinical examination, health and epidemic prevention, biochemical scientific research and other fields.
