Industry's future development trend
The in vitro diagnostic industry is produced along with the development of modern laboratory medicine and is an important part of the bio-industry. In vitro diagnosis has become an increasingly important part of human disease prevention, diagnosis and treatment, and is an increasingly important part of safeguarding human health and building a harmonious society. At present, about two-thirds of global medical decision-making is based on diagnostic information, but the expenditure on diagnosis only accounts for about 1% of total medical expenditure, further improving diagnostic techniques and means, increasing diagnostic expenditures, and can be used for human diseases. Prevention, diagnosis, and treatment provide a more scientific basis for decision-making, and are also an important direction for future development.
From a technical point of view, the future development of biochemical diagnostic technology mainly focuses on the improvement of the quality of the original testing project and the development of new testing projects brought about by technological advancement. In terms of improving the quality of the original inspection project, traceability is especially important in the field of biochemical diagnosis based on open systems. After the open system is compared with traceability, inter-room quality assessment or clinical specimens, and the corresponding standard operating procedures are established, the accuracy and comparability of the test results will be significantly improved. In the development of new testing projects, the sensitivity of the automatic biochemical analyzer has been greatly improved due to the application of latex-enhanced immunoturbidimetric and colloidal gold-enhanced immunological techniques, so that some items originally used for immunoassay can be detected on an automatic biochemical analyzer. . At the same time, some new technologies, such as therapeutic drug testing (TDM), enzymatic methods and homogeneous immunoassay, have begun to use biochemical diagnostic methods.
From the perspective of industry regulatory policies, the state's laws and regulations and industry policies on the in vitro diagnostic industry will gradually converge toward international practices. The series of management measures for in vitro diagnostic reagents issued by the State Food and Drug Administration since 2007 fully reflect the general principles of the in vitro diagnostic industry supervision in developed countries in Europe and America. Since mid-2014, the national regulatory authorities have gradually strengthened supervision of the IVD industry. A series of related policies and documents have been issued, and monitoring has been strengthened from research and development, production, registration, clinical, circulation, sales and other aspects. Through strict industry access and operational requirements, the IVD industry has been extensively shuffled to quality. Leading manufacturers of the core market segments will benefit from the implementation of this policy, and the market share of domestic brands will gradually concentrate.
From the perspective of industrial policy, the state attaches importance to the development of biotechnology and its industrialization, and the bio-industry including in vitro diagnosis has received comprehensive government policy support. The State Council, the National Development and Reform Commission, and the Ministry of Science and Technology have also talked about it in many documents. The diagnosis includes the National 12th Five-Year Plan for Science and Technology Development, the 12th Five-Year Plan for Biotechnology Development, and the 12th Five-Year Plan for Medical Device Technology. In September 2015, the General Office of the State Council issued the “Guiding Opinions on Promoting the Construction of Graded Diagnosis and Treatment Systemâ€, and deployed to accelerate the construction of a graded diagnosis and treatment system, form a scientific and orderly medical treatment pattern, improve people's health, and further protect and improve people's livelihood. Graded diagnosis and treatment allows patients to be diverted to primary medical institutions, and imported brands are unable to over-sink, which is good for domestic brands. In the sixtieth chapter of the "13th Five-Year Plan" promulgated in March 2016, the promotion of healthy China is also proposed to deepen the reform of the medical and health system, adhere to the principle of prevention, establish and improve the basic medical and health system, and realize people. People enjoy basic medical and health services, promote fitness for all, and improve people's health. The support of industrial policies in these countries has created a good external environment for the development of the in vitro diagnostic industry. Under the background of the overall industrial situation, the in vitro diagnostic industry has also benefited from the wave of industrial development.
From the perspective of enterprise development strategy, the international in vitro diagnostic industry giants have adopted the development model of “reagent + instrument†integration, such as Siemens (Siemens), Roche (Roche), Beckman (Beckman) and so on. Kehua Bio, one of the leading in-country diagnostics industry, has gradually evolved from a purely diagnostic reagent manufacturer to an all-round company that integrates reagents and instruments, and can provide a variety of products in medical diagnostic related fields. Therefore, the integration of instruments and reagents is an inevitable trend in the development of the in vitro diagnostic industry.
Everything You Need To Know About LED Lighting
LEDs are a simple invention with huge potential to change the lighting industry for the better. Don`t know much about them? Here are three big things you need to know to get your feet under you:
1.What Does LED Stand For?
2.LED stands for light-emitting diode.
A diode is an electrical device or component with two electrodes (an anode and a cathode) through which electricity flows - characteristically in only one direction (in through the anode and out through the cathode). Diodes are generally made from semi-conductive materials such as silicon or selenium - substances that conduct electricity in some circumstances and not in others (e.g. at certain voltages, current levels, or light intensities).
2.A light-emitting diode is a semiconductor device that emits visible light when an electrical current passes through it. It is essentially the opposite of a photo-voltaic cell (a device that converts visible light into electrical current).
Did You Know? There is a similar device to an LED called an IRED (Infrared Emitting Diode). Instead of visible light, IRED devices emit IR energy when electrical current is run through them.
1.How Do LED Lights Work?
2.It`s really simple actually, and very cheap to produce, which is why there was so much excitement when LED lights were first invented!
The p-type and n-type materials are created by introducing the original material to atoms of another element. These new atoms replace some of the previously existing atoms and in so doing, alter the physical and chemical structure. The p-type materials are created using elements (such as boron) that have less valence electrons than the intrinsic material (oftentimes silicon). The n-type materials are created using elements (such as phosphorus) that have more valence electrons that the intrinsic material (oftentimes silicon). The net effect is the creation of a p-n junction with interesting and useful properties for electronic applications. What those properties are exactly depends mostly on the external voltage applied to the circuit (if any) and the direction of current (i.e. which side, the p-type or the n-type, is connected to the positive terminal and which is connected to the negative terminal).
Application of the Technical Details to LED Lighting:
When a light-emitting diode (LED) has a voltage source connected with the positive side on the anode and the negative side on the cathode, current will flow (and light will be emitted, a condition known as forward bias). If the positive and negative ends of the voltage source were inversely connected (positive to the cathode and negative to the anode), current would not flow (a condition known as reverse bias). Forward bias allows current to flow through the LED and in so doing, emits light. Reverse bias prevents current from flowing through the LED (at least up until a certain point where it is unable to keep the current at bay - known as the peak inverse voltage - a point that if reached, will irreversibly damage the device).
