How to increase safety in medical power devices?

With the continuous development of the medical industry, the technology and quality of medical devices are growing consequently, leading to continuous innovation and an increase in all related products. Considering their key role, the demand and requirements of medical power supplies are becoming a priority during the construction phase.

The way in which the development of the medical industry meets the product performance, as well as distribution, quality, safety certificates, and so on, is what medical power supplies must consider and achieve as a goal.

1. 'Safety' and 'Compliance': the foundations of medical power supply

The most important focuses of medical power devices are safety and compliance: safety depends on the power supply meeting the requirements of the EN60601 medical industry certificate, which includes current leakage, safety distance, etc.; compliance reflects on production and materials, which must ensure sufficient consistency, as well as the control process must be effective and reasonable and anything non-compliant must be avoided.

Compliance standards include safety and EMC. Safety regulations are a mandatory criterion, and this depends solely on the product design. EMC is a compliance criterion, the power supply itself must meet these requirements. At the same time, it is essential to consider the overall design of the entire system, wiring, casing, and so on.

2. How to design high-quality medical power supplies: a brief analysis of design

The EN60601 medical certification

Taking the Mornsun LOF series as an example, the product has a 5-year warranty and safety specifications comply with IEC/EN/ES 60601 standards, ensuring current leakage is less than 0.1mA (perfect for BF type medical devices), as well as insulation and safety distance compliant with standards.

EMC Design

The requirements of medical power supplies on minimum current leakage, safety distance, and high-power density are interrelated constraints that must be considered.
