What aspects should be paid attention to in the appearance inspection of switching power supplies in the medical industry?
In the development and production process of medical power modules in recent years, they have gradually shown a trend of integration and specialization. Different from the requirements for large battery power consumption and power consumption in industrial applications, the module power supply used in the medical profession is more inclined to miniaturization and professional reliability in application selection. This article will specifically introduce the medical power module in the development process of the need to meet several application standards.
The power module used in the medical profession should have the following characteristics
Small size and high power density. The power module used in the medical profession, under the premise of meeting the global voltage input requirements, the volume must be reduced as much as possible, which can save a lot of component space for small medical equipment, and also provide the possibility for the miniaturization of equipment.
It is necessary to have high reliability. The power supply requirements for medical use are designed according to the requirements of industrial grade products, and the working temperature must meet the scale requirements of -25-70 degrees Celsius. And the medical power supply needs modular design, internal use of thermal potting glue and international standard pins. Industrial grade product design provides a guarantee of product reliability, and standardized pin packaging reduces the customer's potential single supply risk.
It is necessary to ensure the safety of the module power supply. The engineer needs to design the circuit system according to the requirements of the medical power supply, and the power supply used must be a CLASS II device. In the safety design, the interval between the input and output reaches more than 8mm, and the pressure requirement reaches 4000VAC/1min. The product requirements of medical power supply are designed according to the international standard ROHS requirements.
In addition to the points mentioned above, the module power supply for medical purposes also needs to have a low EMI function to ensure that the power supply will not cause body failure due to electromagnetic interference in emergency or more complex environments, so as to fundamentally ensure the safety and stability of the patient in the treatment process.
