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 an article explicitly states that it only applies to ME devices or ME systems, the title and the text of the chapter or article will indicate this. If this is not the case, the relevant chapter or article applies to both ME devices and ME systems.
Except for 7.2.13 and 8.4.1, this part does not specify the hazards (sources) caused by the intended physiological effects of ME devices or ME systems within its scope.
In GB 9706.1—2020, 1.1 is replaced by the following content:
This part specifies the basic safety and basic performance of ventilators (also referred to as ME devices) used in combination with accessories, such ventilators being:
——intended for use in home care environments;
——intended to be operated by inexperienced operators;
——intended to be used to support patients' lives by relying on ventilators.
Note 1: Such ventilators are also suitable for patients who do not rely on ventilatory support.
Note 2: When used in home care environments, the power sources of such ventilators are often unreliable.
Note 3: Such ventilators are also suitable for non-critical patient monitoring work areas in professional healthcare institutions.
The provisions of this part also apply to accessories that the manufacturer intends to connect to VBS or ventilators, and the characteristics of such accessories may affect the basic safety and basic performance of ventilators.
Examples: breathing tubing, connectors, water collecting cups, exhalation valves, humidifiers, VBS filters, external power supplies, and distributed alarm systems, etc.
If a chapter or an article only applies to ME devices or ME systems, the title and
