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 chapters or articles apply 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 basic safety and basic performance of sleep apnea treatment devices, which are defined as devices intended to alleviate the symptoms of obstructive sleep apnea by providing therapeutic respiratory pressure to the patient's respiratory tract; sleep apnea treatment devices are intended for use in home health care environments by non-professional operators, as well as in professional medical institutions.
This part does not include sleep apnea treatment devices for newborns.
This part applies to ME devices or ME systems used by patients who do not rely on mechanical ventilation.
This part does not apply to ME devices or ME systems used by patients who rely on mechanical ventilation, such as those used by patients with central sleep apnea.
This part also applies to accessories that the manufacturer intends to connect to sleep apnea treatment devices, when the characteristics of these accessories may affect the basic safety and basic performance of sleep apnea treatment devices.
Sleep apnea treatment masks and application accessories are separately mentioned in ISO 17510:2015. The components covered in this part are referenced in Figure AA.1.
