introduction
In recent years, with the high sensitivity of electronic technology is widely used in medical electrical equipment and new communications technologies, such as personal communication systems, cellular
Telephone, the rapid development in all spheres of social life; not only their own medical electrical equipment will emit electromagnetic energy, the impact of radio communications
Services and work around other devices, but also in its use by the surrounding environment may also interfere with communications equipment, such as electromagnetic energy emitted making
A pair of patient injury. Electromagnetic compatibility for medical electrical equipment as it relates to public health and safety, and a growing concern to all countries.
The necessity of medical electrical equipment and medical electrical systems (referred to in this collateral standard equipment and systems) standards for electromagnetic compatibility has become
Widespread consensus.
Electromagnetic emission standards developed primarily for protection. safety services, other equipment and systems, non-medical electrical equipment (such as computers), radio communication
Information (such as radio/TV, telephone, radio, navigation). Electromagnetic immunity standards developed primarily to ensure the safety of equipment and systems.
Electromagnetic compatibility (see the definition 2.204) Unlike other security GB 9706.1 covered, because all the equipment and systems
In normal use of the system environment there are different severities of electromagnetic phenomena, and specifies that it expects the device to form an electromagnetic environment
Compatible must be "satisfied to run." This means that the traditional concept of a single fault does not apply to security-related electromagnetic compatibility standards.
IEC 60513 describes the difference between safety standards and performance standards is often unclear. Equipment and systems used in medical practice because
As they provide the required functionality. If the devices and systems 1) the expected event in the normal use of the environment due to lack of immunity and can not be mentioned
For the required function, the case of medical practice and unacceptable interference will occur. Therefore, IEC 60601-1-2 standard and the second edition of the first edition
The difference is. the anticipated degree of electromagnetic disturbance power in peacetime, establishing a minimum baseline performance.
This standard is considered between manufacturers, customers and users to ensure that the equipment and system design and operation as expected have a shared responsibility.
Equipment or system manufacturer's responsibility is to meet the requirements of this standard design and manufacturing, and customer or user of public information for peacekeeping
Achieve the purpose of retaining devices or systems compatible electromagnetic environment can run as expected.
Because medical practice includes many professional and therefore need to design multi-functional devices and systems. Some features, such as. micro-patient
Weak signal measurement, electromagnetic immunity tests of the weak signal level specified in this standard is coupled to the electromagnetic noise level of equipment and systems
It is very low in comparison. Because many of these devices and systems have been shown to have benefits, so it based on the physical aspects, technical aspects or physiological side
Limitation surfaces provide sufficient grounds to consider under this standard allows reduced immunity test level. In this case, the manufacturer must be open
Equipment or system to meet the level of the standard performance requirements, and provides for the use of the electromagnetic characteristics of the environment and how to create such an environment, so that the device
Or the system is running as expected.
This standard also think some environments may require a higher level of immunity. How to determine may require a higher level of immunity to the environment
And should provide the kind of level, we are being studied.
The standard recognizes that the life-support equipment and systems, in order to establish a broader safety margin, even in a normal environment to make medical use
Used, it must have a higher level of immunity. Therefore, the standard of life support equipment and systems provides for additional requirements.
This standard TC62/SC62A, TC77 (electromagnetic compatibility including network, including electrical devices) and CISPR (International Wireless
Special Committee on the current IEC standard electrical interference) developed based.
This standard specifies electromagnetic compatibility requirements are generally applicable to equipment and systems as described in 1.201. For certain types of devices
And systems, these requirements may need to be modified by the special requirements of specific standards. Encourage specific standard writers refer to Appendix D for
Application of this standard guidelines.
1) This standard, "or" sometimes can be understood as including the "and."
