6.2.101 Risk assessment and EMC immunity requirements
In some environments, high-power electromagnetic emission sources can cause nearby medical equipment to malfunction. Different types of medical electrical equipment are Different failure risk levels. Because IVD medical devices are not used for patient life support or resuscitation, malfunctions do not directly cause patient death or severely injured. Malfunctions in IVD medical electrical equipment may cause erroneous indications, leading to erroneous medical diagnosis (misdiagnosis). for Some analytes and in some cases, wrong conclusions can cause serious harm to patients. For large IVD medical equipment, electricity Magnetic disturbances can also cause malfunctions that directly threaten the operator, for example, unexpected mechanical movements. Guidance on direct hazard risk assessment is provided in ISO 14971. Guidance for assessing risks to patients from incorrect findings Annex H of ISO 14971..2000.
Note. Generally, conclusions made by IVD medical devices are checked by medical personnel for their credibility, or further decisions are made by health care professionals. For ordinary users Self-tested IVD medical devices often recommend actions to be taken without a clear conclusion. Users are required to contact their doctor before making a decision. The risks of using IVD medical devices are similar to those of non-life-supporting medical devices. Therefore, the immunity test given in Table 1 requires The requirements are similar to those for non-life-supporting medical devices.
