YY 0989.6-2025 Implants for surgery—Active implantable medical devices—Part 6:Particular requirements for active implantable medical devices intended to treat tachyarrhythmia(including implantable defibrillators)

This document specifies the requirements for active implantable medical devices (including implantable defibrillators) used in the treatment of tachyarrhythmia.
This document applies to implantable cardioverter-defibrillators, implantable cardiac resynchronization therapy/defibrillators, active implantable medical devices with the function of treating tachyarrhythmia, and certain non-implantable components and accessories of active implantable medical devices (see note).
This document does not apply to active implantable medical devices used in the treatment of bradyarrhythmia or cardiac resynchronization. GB 16174.2-2024 specifies such requirements.
Note 1: The tests specified in this document are type tests, and conformity is confirmed through testing of samples.
Note 2: The characteristics of implantable pulse generators or electrode leads are verified using appropriate methods described in this document or other methods, provided that the accuracy of these other methods can be proven to be equal to or superior to the specified methods. In case of dispute, the methods specified in this document shall prevail.
Note 3: What is commonly referred to as "active implantable medical devices" may actually be a single device, a combination of multiple devices, or a combination of one or more devices with one or more accessories. Not all of these components are partially or fully implantable, but if non-implantable components or accessories may affect the safety and performance of the implantable device, requirements for non-implantable components and accessories must be specified.

YY 9706.287-2025 Medical electrical equipment—Part 2-87:Particular requirements for basic safety and essential performance of high-frequency ventilators

This document specifies the basic safety and performance requirements for high-frequency ventilators (HFV) used in combination with accessories (hereinafter referred to as "ME devices").
This document applies to patients who may be at risk of life-threatening conditions and require comprehensive care and continuous monitoring in professional medical institutions, operated by professional medical staff. It provides high-frequency ventilation of more than 150 breaths per minute for patients requiring different levels of artificial ventilation support, including those dependent on ventilators.
Note 1: In this document, such environments are referred to as critical care environments. High-frequency ventilators used in such environments are considered life-support devices.
Note 2: In this document, such high-frequency ventilators can provide transport in professional medical institutions (e.g., as a functioning ventilator during transport).
Note 3: High-frequency ventilators used for transport in professional medical institutions are not considered emergency medical service environment ventilators.
Note 4: HFVs are primarily categorized into three types: — High-frequency percussive ventilation (HFPV, typical HFV frequency: 60 breaths per minute to 1,000 breaths per minute); — High-frequency jet ventilation (HFJV, typical HFV frequency: 100 breaths per minute to 1,500 breaths per minute); — High-frequency oscillatory ventilation (HFOV, typical HFV frequency: 180 breaths per minute to 1,200 breaths per minute, typically with an active exhalation phase).
Additionally, HFV nomenclature may be combined or used in conjunction with ventilators operating at a frequency below 150 breaths per minute.
*High-frequency ventilators are not considered physiological closed-loop control systems, unless they use patient physiological variables to adjust ventilation therapy settings.
