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 clause explicitly states that it only applies to ME devices or ME systems, the title and the text of the chapter or clause will indicate this. If this is not the case, the relevant chapter or clause 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 document specifies the basic safety and basic performance of respiratory support devices (see 201.3.205 definition, also known as ME devices) used in combination with accessories for respiratory dysfunction (see 201.3.202 definition).
This document applies to respiratory support devices intended for use in home care environments by inexperienced operators for patients with respiratory dysfunction.
Note 1: The most vulnerable of these patients will not be harmed by the loss of artificial ventilation.
This document also applies to accessories of ME devices that the manufacturer intends to connect to ME devices, the characteristics of which may affect the basic safety and basic performance of ME devices.
Example 1: Respiratory tubing, connectors, water traps, exhalation valves, humidifiers, VBS filters, external power supplies, and distributed alarm systems, etc.
This document does not apply to equipment for patients who rely on artificial ventilation for life support in real time.
Example 2: Patients with mild to moderate chronic obstructive pulmonary disease (COPD).
Note 2: In home care environments, power sources are often unreliable.
Note 3: Such respiratory
