 In the International Electrotechnical Commission IEC60364 standard provides, in the medical field, from the power supply, or surgery for life-sustaining medical electrical equipment and lighting for theater lighting and similar equipment, the rated voltage of the device over AC25V or DC60V , insulation resistance must be used with Monitor IT systems. Meanwhile, China's "civil electrical design specifications," in 14.7.6.3 provides that "a sudden interruption in power, have incurred significant medical risk places should be non-grounded power system (IT system) power supply"; 14.2.8 in provides "IT systems must be installed insulation monitoring and ground fault alarm system or display device." And China November 26, 2002 release, 12 January implementation of the "hospital clean operating department building technical specifications" 8.3.1.3 states that "clean power from the surgical department specially equipped building supply distribution centers, according to use place, they mainly use TN-S system and IT systems in two forms "; 8.3.2.3 states that" power should be clean operating room equipment, leakage detection and alarm devices "; 8.3.4.2 provides that" must be set to a cardiac surgery operating room isolation transformer functional grounding system "and other relevant regulations. Third, the new (changed) to build hospitals use IT system design: 1. In the medical field all to examination or treatment for the purpose of the device in direct contact with patients (including lead), there are three applications: ● Apply Group Class 0 : The medical establishments do not use grid power for medical electrical equipment. For example: patient rooms, waiting room, massage room, etc. ● Applications Group Class 1: The use of health facilities within the power supply of medical electrical equipment, these devices do not insert any part of the patient's body. For example: the ward, maternity wards, X-ray room ● Applications Group 2: The use of grid power supply health facilities with medical electrical equipment, these devices for cardiac surgery or within the human body, real-time monitoring of the patient or for the maintenance of the patient's life, etc. role. For example: anesthesia room, operating room, surgery preparation room, surgery, plaster room, a surgery recovery room, cardiac catheterization rooms, intensive care unit, cardiac care unit, angiography rooms, child care room in the premature application of medical group 2 class place, insulation resistance must be monitored with an isolated power supply systems (IT systems). 0 in the application of group classes and one class of health facilities, can be used with ground leakage current protection system, the TN-S system. (2) recommended grid electricity access to IT equipment: a) ventilator b) incubator c) dialysis equipment d) anesthesia equipment e) patient monitoring equipment f) high-frequency surgical equipment g) infusion pump h) injection pump i) heart-lung machine j) effort recorder k) pulse pressure machine l) rhythm and other electronic pulse modulator 3 the operating room / ICU ward / CCU ward IT power system basic configuration: ⑴ ⑵ isolation transformer insulation monitoring device ⑶ transformer load and temperature monitoring external alarm display device ⑷
