YY 9706.247-2021 Medical electrical equipment—Part 2-47:Particular requirements for the basic safety and essential performance of ambulatory electrocardiographic systems
Basic Information
Scope
This part of GB 9706 specifies the general requirements for the basic safety and basic performance of ME devices and ME systems.
This part applies to medical electrical equipment and medical electrical systems (hereinafter referred to as ME devices and ME systems).
If a chapter or section explicitly states that it only applies to ME devices or ME systems, the title and the text of the chapter or section will indicate this. If this is not the case, the relevant chapter or section applies to both ME devices and ME systems.
Except for 7.2.13 and 8.4.1, the hazards (sources) caused by the intended physiological effects of ME devices or ME systems within the scope of this part are not specifically required in this part.
This part specifies the special requirements for the basic safety and basic performance of dynamic ECG systems.
This part applies to the basic safety and basic performance of dynamic ECG systems (hereinafter referred to as ME systems).
If a chapter or section only applies to ME devices or ME systems, a clear statement will be given in the title and content of these chapters or sections. If no such statement is made, the chapter or section applies to both ME devices and ME systems.
Except for 7.2.13 and 8.4.1 of the general standard, the inherent hazards of the intended physiological functions of ME devices or ME systems within the scope of this part are not included in the specific requirements of this part.
Note: See General Standard 4.2.
The following types of systems are within the scope of this part:
a) Systems that can continuously record and analyze ECGs, and the system can provide essentially the same results when performing a complete re-analysis of the ECG. This system may first record and store the ECG, then analyze it in a separate unit, or perform recording and analysis simultaneously. This standard does not address the type of storage medium used.
b) Systems that can provide co
