Nowadays, with the continuous progress of science and technology, more and more modern medical equipment has been rapid developed, especially the direct contact with the body of electronic instruments, in addition to the performance of the instrument itself increasingly demanding than outside, consider human safety is also growing concern. For example: cardiac puncture monitors, ultrasound, baby monitors, baby insulation meter, monitor and some life in close contact with the body of the instrument, That is the patient using the instrument, not because of the use of the instrument and on the human body in any danger of electric shock or other aspects.

With the medical equipment technology and improve the protection of medical devices is also a growing concern. Hospital DSA, CT, ECT, ultrasound, automatic biochemical analyzer and ICU, CCU monitoring system easily hundreds of thousands or even millions, not only expensive, but also very high precision products, the slightest slip would make the whole system. (Complete annihilated.) In recent years, China "power shortage" increasingly serious, when the peak power cuts, innovative high power load. These adverse factors threatening medical devices are growing. In addition, due to the special nature of the hospital, if you experience a sudden power failure, it will bring irreparable damage to the patient. Establish and improve the health care system facilities is imminent. Therefore, the medical supply equipment for the normal operation of the entire health care system plays a vital role.
