What Is a Medical Power Supply?

In today's society, with the continuous advancement of science and technology, more and more modern medical devices have been developed rapidly, especially electronic instruments that are in direct contact with the human body. In addition to the increasing requirements for the performance of the instruments, Human safety considerations are also receiving increasing attention. For example: cardiac puncture monitors, ultrasounds, mother-to-child monitors, baby warmers, life monitors and other instruments that are in close contact with the human body. Any danger. Medical electronics, unlike other electronics and power electronics that are targeted at the mass market and cost-conscious consumer electronics and other low-cost product applications, have more rules to follow. If the designer is responsible for system power design, the first question for the system power supply part is whether to buy or manufacture a solution. Because medical electronics production is generally relatively low, designers must consider the issue of purchase or self-control. Designers of medical electronics rarely consider designing their own offline power supplies. Because the investment required for this particular type of design and testing does not match the final production scale, equipment manufacturers may find it difficult or impossible to distribute the investment in the design phase. Therefore, it is more cost-effective to directly purchase power supplies from companies that already have the corresponding professional design capabilities and testing technologies.

In commercial application design, if the quality is guaranteed, it is easy for people to directly select the lowest-priced power supply product after shopping around. At this time, the product with the lowest price but "decent" is often the winner, while the best product is not welcome. This is not bad for disposable electronic products that will soon be obsolete or require no maintenance, but if designers choose any such power supply to use in medical systems, what are the risks? Medical electronics are of high value There are some key tasks that need to be completed. If the medical system goes down, the consequences are more than just a missed race or a wrong ride. The normal operation of medical equipment is vital, especially the power supply of medical equipment, which must meet the relevant regulations on safety, leakage, EMI-RFI radiation and protection. These standards and related safety regulations constitute a set of strict regulatory requirements. Power supplies used in such demanding applications must meet strict specifications for insulation measures to prevent patients and medical personnel from electric shock. EMC is also a key issue, including how to reduce electromagnetic radiation and how to protect it. Therefore, for the design of medical power supply, the quality and reliability of the product must be the first choice. Designers are often confused about commercial power supplies and medical power supplies, and manufacturers that manufacture various low-cost power supplies for the mass market may sell these commercial power supplies as medical power supplies without modification. In this regard, buyers must be careful, because the choice of such power products because of the desire for cheap will have terrible consequences. Therefore, designers need to understand the relevant rules and regulations.
