Development History of Common Biochemical Analytical Instruments in Hospitals
Views:11208 Date:2019-02-25
With the advancement of science and technology, the development of hospital inspection technology has also continuously raised higher requirements for biochemical analysis instruments. It not only provides a scientific basis for the diagnosis of diseases, but also provides an important reference for the prevention and treatment of diseases. Here are some of the development history of biochemical analytical instruments commonly found in hospitals.

Blood cell analysis equipment

The blood cell analysis device is an instrument that can analyze the number of different types of cells in the human blood and related parameters. The instrument has certain guiding significance for the diagnosis of most diseases, and it is one of the instruments widely used in hospital clinical testing.

Since the 1950s, the introduction of a blood cell counter designed by the principle of electrical impedance technology has revolutionized the analysis of blood cells in clinical tests. This technique is widely used in the design of automated blood cell analyzers; Due to the application of floating landmarks and other techniques, whole blood platelet counts can be realized; in the 1990s, the three-group blood analyzer began to be widely used and blood cell automatic smear and classification instruments were introduced; since the beginning of this century, the fully automatic 5-point blood analyzer has become The main instruments for routine inspection in the inspection departments of major hospitals.

With the continuous increase in blood sample volume in recent years, a new blood cell analysis system, the blood cell analysis pipeline, has been introduced to the market and has achieved good results. The analysis system combines one or several high blood cell analyzers with one or several blood cell smears and dyeing integrated machines to form a blood cell analysis with higher automation, full analysis speed, and more intelligent effects. system.

Urine analysis equipment

Urine analysis refers to the morphological analysis of chemical substances and morphological components in urine, including routine urine analysis, formation of urine components (such as urinary red blood cells, white blood cells, etc.), quantitative determination of protein components, urine enzyme determination, etc. . Urine examination is of great significance for clinical diagnosis, judgment of efficacy and prognosis.

In the 1950s, the urine analysis reagent strip appeared to facilitate the analysis of urine; in the 1970s, the semi-automatic urine analysis solution was applied; in the 1980s, the automatic analyzer for urine sediment was successfully developed, which realized the quantitative analysis of urine and improved urine. The sensitivity and specificity of liquid analysis; the automatic urine analyzer and urine sediment analyzer in the 1990s have successively asked the market, which not only reduced the labor intensity of clinical laboratory personnel, but also greatly improved the speed of urine analysis.

In recent years, urine analysis has been rapidly developed in two aspects. First, the "machine vision" technology is applied to the analysis of urine sediment. This technology is formed by CCD ingesting cells in urine sediment, and then analyzing and identifying according to its inherent parameters. , classification, counting. The formed image of the CCD is also reproduced on the display by an electronic computer, which can greatly reduce false positives in the urine sediment analysis process. The second is to connect the automatic urine dry chemical analyzer with the automatic urine sediment analyzer through the track to form an automatic urine analysis workstation.

Clinical biochemical analysis equipment

Clinical biochemical testing techniques, testing items and testing instruments have a leading position in the development of clinical laboratory disciplines. Clinical biochemical testing instruments were first produced in the 1950s.

The semi-automatic biochemical analyzer was introduced in the 1960s; the automatic biochemical analysis in the 1970s began to be used in clinical laboratories. In the late 1980s, China began the development of semi-automatic biochemical analyzers. So far, dozens of manufacturers in China have been able to produce semi-automatic biochemical analyzers. In the late 1990s, some domestic enterprises and research institutes began to develop fully automated biochemical analysis. instrument.

Nowadays, automatic biochemical analyzers have embarked on a rapid development path with a higher degree of automation, a wider range of analysis projects, easier configuration, faster analysis and easier maintenance.

With the advancement of modern medical care, biochemical analytical instruments are always following the footsteps of the times and constantly innovating to meet our testing needs. In the future, along with the growing maturity of science and technology, biochemical analytical instruments are gradually developing towards openness, rationalization, automation, intelligence, combination, networking and cutting-edge. We expect these instruments to better benefit our lives and make more contributions to the medical testing industry.
