What structural system is the automatic biochemical analyzer composed of?

The biochemical analyzer is an instrument that uses the photoelectric colorimetric principle to measure a specific chemical composition in body fluids. It is used to detect and analyze life chemical substances, and provide information basis for clinical diagnosis, treatment, prognosis and health status of diseases. Mainly detect liver function, kidney function, blood sugar, blood lipids, etc. The automatic biochemical EEG machineanalyzer mainly consists of a sample system, a cleaning system, an optical system, a temperature control system and a software system. Let me introduce it in detail below.

1. Meilun sample system

Samples include calibrators, quality control products and patient samples. The system generally consists of sample loading, transport and distribution devices.

2. Meilun cleaning system

In the automatic biochemical analyzer, the reaction cup cleaning can be achieved by two schemes, namely, the reaction cup is cleaned in the machine and the reaction cup is automatically replaced. The reaction cup is cleaned inside the machine, and the reaction cup is used repeatedly. The cleaning process includes the steps of sucking up the reaction solution, injecting acidic cleaning agent, sucking up the acidic cleaning agent, injecting alkaline cleaning agent, sucking up the alkaline cleaning agent, injecting deionized water (may have multiple times), and drying the reaction cup. The effect of cleaning directly determines the contamination of the instrument. The disadvantage of in-machine cleaning is that it is difficult to ensure that the reaction cup is thoroughly cleaned, so errors caused by contamination of the reaction cup are inevitable; moreover, the water consumption is relatively large.

The automatic replacement of the reaction cup adopts a disposable reaction cup, so the pollution of the instrument will be greatly reduced; at the same time, because the repeated cleaning process is reduced, the reliability of the instrument can be further improved, and the water consumption of the instrument will be greatly reduced.

3. Meilun optical system

EEG machineMost of the light sources of biochemical analyzers are halogen lamps, which are simple, low cost, easy to adjust and control brightness, and good color rendering, so they are widely used in biochemical instruments.

4. Temperature control system

Various biochemical reactions, especially enzymes, are very sensitive to temperature fluctuations. A constant temperature is required to obtain reliable and accurate results. Generally, the temperature fluctuation of the reaction chamber is required to be controlled at ±0.1°C. At present, the most commonly used methods include air bath, constant temperature water bath, and constant temperature liquid heating method.

5. Meilun Software System

The operating software of the biochemical analyzer can be applied to a variety of systems, such as: WindowsXP, Windows7, Windows8, using the commonly used USB communication interface, the software functions mainly include three aspects: one is to provide users with an interface for operating the instrument; the other is to control The various parts of the instrument work to achieve various biochemical analysis methods and some auxiliary functions; the third is the analysis, processing and calculation of data. In addition, the automatic biochemical analyzerEEG machine also has a series of automatic alarm functions: such as automatic inspection and alarm for sample results, automatic detection and automatic identification and alarm when reagents or standards are exhausted, automatic inspection and alarm for calibration results.
