What is the difference between medical power supplies and regular power supplies?

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.05.09
In today's society, with the rapid development of power technology and the increasing demand for equipment in the medical industry. After all, medical devices are electronic devices that come into direct contact with the human body. Firstly, the performance and accuracy of electronic devices are highly required, and the safety of the power supply equipment used in electronic devices must comply with national regulations. In the medical industry, there are many electronic devices, such as ultrasound X-rays, fetal monitors, and life monitors, that come into direct contact with the human body. When using these devices, it is necessary to avoid contact and radiation between the device and the human body. Therefore, there are strict requirements for the design and use of medical power supplies.

Medical power supply is a power supply device that provides power security for medical equipment and institutions. Due to the high requirements of medical equipment for power quality, power supply reliability, and safety, medical power sources also have stricter standards and regulations.

1. What does medical power supply refer to？

Medical power supply refers to power equipment specifically designed and manufactured for medical equipment and institutions to meet their needs, including uninterruptible power supplies (UPS), battery chargers, high-frequency electrocuttons, electric operating tables, etc.

2. Medical power supply certification standards:

Medical power supplies must comply with relevant certification standards in the design, production, sales, and use process, such as IEC60601-1, UL2601, EN60601-1, GB9706.1, etc. These standards mainly involve electrical safety, structural safety, and EMC (electromagnetic compatibility) of products, ensuring the quality and reliability of medical power supplies.

3. Differences between medical power sources and regular power sources:

Medical power sources have their unique design and requirements compared to ordinary power sources. On the one hand, medical power supplies must meet the standards of Class I or Class II medical equipment, ensuring the safety and reliability of the product; On the other hand, medical power sources also have higher requirements in their use, such as having self diagnosis and self repair functions, and being able to quickly switch to backup power sources.

The difference between medical power supplies and regular power supplies is that medical power supplies have insulation requirements, leakage current requirements, and residual voltage requirements.

1.If it is an inverter power supply, the waveform requirements of the medical power supply are stricter and closer to a sine wave;

2. Medical power sources may use purified circuits for AC input to prevent ripple interference;

3. Precise medical equipment has more precise and stable output of voltage stabilizing circuits;

4. Medical power supplies have better reliability and lower failure rates.

Lastly, there is the issue of the price of medical power supplies. Due to the strict standards of medical certification, the price of general medical power supplies will be much higher than that of ordinary ones.
