Biochemistry test: On the basis of studying the changes in the biochemical process of human health and disease, the theory and technology of physics, chemistry, biology, immunology, biochemistry, and specimens The changes in the quantity and quality of Chinese chemicals provide clinicians with disease diagnosis, condition monitoring, efficacy observation, judgment prognosis and health assessment.

The biochemical instrument is mainly for the test medicine of hospitals at all levels to provide clinical chemical chemistry, clinical hematology, clinical immunology and other aspects of inspection items. The measured items include liver function, renal function, blood lipids, blood glucose, specific protein, myocardial signs Things, electrolytes, etc. Providing important scientific basis for the diagnosis, treatment, and prevention of diseases is a necessary monitoring equipment for hospitals.

At the beginning of the 19th century, the original manual method began to detect the samples with rarely biochemical indicators. At this stage, the absorption method of liquids such as samples, reagents, etc. mainly uses the pseudo -pipe tube to manually adjust the amount of suction fluid. Extremely low and error. In the 1950s, with the emergence of automatic diluers, the absorbing of liquids achieved automation or semi -automated, and the semi -automatic ratio meter was applied one after another.

In 1957, since Technicon has created the first biochemical analyzer in the world, there have been different types of automated biochemical analyzers such as centrifugal, continuous liquidity, sannar, bag, and separation. Biochemical inspection has entered the process of automation and intelligence. In 1965, another open instrument was born -separated automated biochemical analyzer. Its working principle is similar to manual operations. The sample is performed in a differential cup of each other.

By the beginning of the 21st century, the concept of the integrated workstation created by De Ling Company was to combine a series of important immune testing with conventional biochemical tests to the same platform. efficiency.

Since the 21st century, the separation instruments have gradually become the mainstream of biochemical analysis. The structural design has been continuously optimized and the functions have gradually improved. The fully automated analyzer forms a complete biochemical detection assembly line, allowing the sample to complete the sample recognition, sample, detection, results transmission, and specimen detection. To improve efficiency more efficiently, save manpower, and provide a strong guarantee for the high -quality development of the department.

Brief Analysis of the Current Development Status and Trend of Chinese Medical Device
Brief Analysis of the Current Development Status and Trend of Chinese Medical Device
  Author:MeCan Medical–ultrasound machine manufacturersAt present, the epidemic is still spreading globally, and international trade and economic growth have stalled. Although the exports of Chinese medical equipment remain stable as a whole, they need to be alert to relevant risks and challenges. The relevant person in charge of the Medical Institution Department of the Medical Insurance Chamber of Commerce pointed out that in the short term, due to the needs of epidemic prevention and immunity, the global market has increased its dependence on the supply chain of Chinese medical device.In the long run, the epidemic has become a catalyst for reshaping the global industrial structure. With the introduction of policies in various countries, international competition will intensify, and the competition between Chinese medical devices in the global market will be more intense.In terms of market risks, the global economic recovery will lower the ability of the international market to procure ordinary medical supplies. The surge in demand for epidemic prevention materials, coupled with the decline in the efficiency of the port work, has caused serious lag in the circulation of containers, bringing a sharp increase in international logistics costs, especially shipping. The rise in raw materials and labor costs, and the strengthening of the supervision of merchants by cross -border e -commerce platforms will further squeeze the export profits of the enterprise.In addition, due to international travel restrictions, it is difficult for engineers and sales staff to conduct promotion activities in overseas markets and after -sales service for some large -scale equipment exported equipment, and it is not conducive to market sales.Overseas market expansion also needs to focus on the impact of changes in international market regulations. For example, the European Union has implemented new medical device regulations (MDR) and in vitro diagnostic medical device regulations (IVDR), pay more attention to the clinical performance of the product, strengthen the traceability of medical device products, and pay attention to improving the transparency of patients.These will improve the management and restrictions on medical device products entering the European market accordingly, and put forward higher requirements for the industry's employees, which will bring about increased costs to Chinese export companies, extending certification cycle, and increasing compliance risks, etc. challenge.

What Are the Steps of Nucleic Acid Detection and What Are the Equipment for Extracting Nucleic Acids
What Are the Steps of Nucleic Acid Detection and What Are the Equipment for Extracting Nucleic Acids
  Author:MeCan Medical–ultrasound machine manufacturersNucleic acid is the carrier of genetic information, an important biological information molecule, and the main object of molecular biology research. Nucleic acid extraction includes DNA extraction, RNA extraction, and plasmid extraction. Regardless of the structure of nucleic acid or functional research, first of all, nucleic acids need to be extracted and purified. Therefore, nucleic acid extraction is an important and basic operation in molecular biology experimental technology. Under the epidemic, the demand for nucleic acid detection is increasing day by day.At present, most of the new coronary virus nucleic acid detection products are mostly adopted by the "real-time fluorescence RT-PCR detection" method. RT-PCR requires two steps for nucleic acid extraction and amplification. The product is mainly divided into two steps during the detection process, namely nucleic acid extraction and amplification detection. Nucleic acid extraction is the starting point of downstream nucleic acid testing, research or product development. The quality and integrity of the separated nucleic acid directly affect the research or diagnosis results.Magnetic pearl nucleic acid extraction instrument is a simple and efficient medical equipment that extract nucleic acid today. Magnetic particles can be removed by permanent magnet in the magnetic field. These magnetic particles can be made of iron oxide particles of the active group. Due to the large surface area and strong ability to combine nucleic acids, it can be used as a better separation carrier. If the container's side wall magnetism is given, the magnetic beads with nucleic acids in the sample mixture are gathered to the container wall, and the container can directly remove other impurities to avoid repeated centrifugation. Magnetic beads are adsorbed by the active group that can be specificly adsorbed.The production of high -throughput and automated nucleic acid extraction methods reduces genetic testing labor costs and makes large number of detection a reality. The magnetic bead method does not require centrifugal, no need to add multiple reagents, simple operation, and automated operations ensure stable experimental results, avoid differences and errors caused by manual operations, and easily meet the standardization of nucleic acid extraction, which meets the requirements of nucleic acid automation extraction requirements. It is an important direction for the development of nucleic acid purification methods.

What Are the Methods of Nucleic Acid Extraction, and the Application Advantage of Nucleic Acid Extra
  Author:MeCan Medical–ultrasound machine manufacturersThe epidemic has entered a normalized management, and the epidemic situation has been repeated in the near future. In order to accurately prevent and control the epidemic, nucleic acid testing has become a key task for the prevention and control of the epidemic. For some hospitals or institutions, the demand for detection is large, and the performance of the nucleic acid extract instrument is getting higher and higher. So, how to choose a nucleic acid extractor in many nucleic acid extract equipment? What are the current methods of nucleic acid extract instruments? What's more?What are the ways to extract the nucleic acid extract instrument?1.Boiling cracking method. This method is generally used for handmade extraction of DNA. The chromosomal DNA is much larger than the plasmid DNA molecule, and the chromosome DNA is a linear molecule, while the plasmid DNA is a covalent -closed loop molecule; when heating the DNA solution, the wire -shaped chromosome DNA is prone to degeneration. When cooling, it restores its natural structure; transgender chromosomal DNA fragments are combined with transgender protein and cell fragments to form a precipitation, while the complex ultra -snoring granular DNA molecule is in a soluble state in a soluble state, so that the two can be separated by centrifugation.2. Mainly use two different organic solvents alternately to remove the protein. When treating uniform slurry with phenols, the protein molecular surface contains a lot of polar groups and phenols similar to the dissolution of the protein molecule. At the same time, the phenol inhibits the degradation of DNase. DNA is dissolved in the water phase.3. High -salt precipitation method is a variant of phenoline pumping method. Using RNP and DNP to dissolve differently in the electrolytic solution, the two are separated.4. Actinoma dewlogen method. Use SDS or sodium toluene, so that the protein degenerates, and DNA can be extracted directly from biomass materials. Because the DNA and protein in the cells are often combined with electrostatic gravitational gravitational or fixing keys, and the anion deodonant can destroy this price bond, the DNA is often used to extract the pollutant of the anion.5. Performing column purification. Through special silicon matrix adsorption materials, it can be specific to be adsorbed, and RNA and protein are successfully passed. Then use high salt and low pH to combine nucleic acids, low salt and high pH value to separate the purified nucleic acid.6. Extraction of magnetic beads. The magnetic bead method uses the principle of combining and dissipating the magnetic acid by the magnetic granular activity group under certain conditions. First use the cell cracking liquid to crack the cells, and the magnetic granules with the active group can be adsorbed by the nucleic acid from the cell in the cell. The molecules, and the other interference in the sample is removed well. Under the action of magnetic fields, the magnetic particles are completed separately from the liquid. Then use the elixir to get rid of it to get the pure DNA, obtain a high -quality nucleic acid template tablet EssenceThe above mainly introduces some methods of nucleic acid extraction. With the actual needs, after the application of nucleic acid extract equipment, it not only improves the speed of detection, but also improves the accuracy of the detection. In addition to these advantages, what are the advantages?A PL-48 nucleic acid automatic extraction instrument produced by Progen Medical adopts a fully automated method. Compared with the manual operation of traditional centrifugation methods, its nucleic acid extraction process is simpler, fast, high, and high extraction rate. At the same time The nucleic acid extract instrument adopts a color touch display, graphic, Chinese and English interface, simple and easy to use, no external computer, no special training. In addition to the outstanding performance advantages of the equipment itself, our manufacturers can provide professional after -sales service. For the actual needs and problems of customers, we will answer time to avoid customers' concerns.

What Is Color Doppler Ultrasound? You Need to Know These Points
What Is Color Doppler Ultrasound? You Need to Know These Points
  Author:MeCan Medical–ultrasound machine manufacturersWhat is color Doppler ultrasound? Color Doppler ultrasound is also known as color Doppler ultrasound. It is a medical device that is suitable for the internal organs of the body, the body, the limb blood vessels and the superficial organs, as well as the abdomen, the gynecological and gynecology. It is based on the pulse Podopler, calculated with motion target display, autocorrelation function, digital scanning conversion, color coding and other technologies to achieve colorful appearances of blood flow.For clinical doctors who want to know the color Doppler ultrasound, the following points need to be known:1. Determine the direction of blood flow The red displayed in the color Doppler ultrasound is not necessarily arteries, and blue is not necessarily vein. Under normal circumstances, red represents the blood flow towards the probe, and blue represents the blood flow from the probe.Of course, red represents the probe, and the blue represents is not unchanged from the probe. It can be set through the machine. In addition, the angle of the color Doppler sampling box can also change the color of the blood flow display, but in order to better present the color blood flow signal, the sample box and the angle of the blood vessel should be as small as possible.2. Preliminary judgment of fast blood flow speed slowlyThe strength of the color Doppler signal can roughly reflect the speed of blood flow, the color signal is bright, indicating that the blood flow is fast, and the color signal is dim that the blood flow speed is slow.3. Recognize arteries and veinsThere are many ways to identify arteries and veins in actual work. Among them, spectrum Doppler is one of the methods we often use, so there is no spectrum Doppler, how should we identify only on the color Doppler ultrasound? Because the arteries are beating, the blood flow signal of the blood flow during the diastolic period is slow and even the blood flow signal is not even blood flow. It can be seen that the arterial blood flow signal flashes, and the color signal is brighter. The venous blood flow speed is low, and there is no contraction period and a diastolic period. Therefore, the blood flow signal appears continuously, and the color signal is dull.4. Determine blood flow natureThe nature of blood flow includes layer flow and turbulence. The colorful blood flow signal of the layer flow is relatively uniform, with a color signal with high brightness in the central part and low brightness at the close tube wall; turbulence shows the colorful inlaid blood flow signal.The application range of color Doppler ultrasound is wider than the B -ultrasound, which can diagnose the lesions more accurately. The accuracy of diagnosis is significantly higher than that of B -ultrasound.
