Introduction

The medical electrical equipment safety standards are also called the 9706 series of standards, which consist of general standards, parallel standards, special standards, guidelines and interpretations.

---General standards. safety standards that should be generally applicable to medical electrical equipment, that is, equipment that meets the definition of medical electrical equipment should meet this Basic standards.

--- Parallel standards. safety standards that should be generally applicable to medical electrical equipment, but in most cases are limited to those with certain specific functions or characteristics. Only devices that are suitable for this purpose need to meet such standard requirements.

---Special standards. safety standards that apply to a certain type of medical electrical equipment, and not all medical electrical equipment has a special standard. standard.

---Guidelines and interpretations. application guidance and interpretations of relevant requirements in the standards involved. Items marked with an asterisk (*) in this document have specific guidance and rationale related to that item in Appendix AA. The relevant contents are considered to be helpful for the correct application of this specific standard, and any version will be revised when the clinical application changes or the technology is updated. It will also be used when making necessary revisions. Medical electrical equipment Part 2-87: High frequency respiration Particular requirements for basic safety and essential performance of machines 201.1 Scope, purpose and related standards Except as follows, Chapter 1 of the general standard applies. Note. The general standard is GB 9706.1-2020. 201.1.1 *Scope replace. This document specifies the basic safety and essential requirements of high frequency ventilators (HFV) (hereinafter referred to as "ME EQUIPMENT") used in combination with accessories. performance. This document is intended for use in professional medical institutions by professional medical personnel for patients whose conditions may be life-threatening and require comprehensive Provide professional nursing care to patients requiring varying levels of artificial ventilation support (including ventilator-dependent patients) A high-frequency ventilator that provides inflations in excess of 150 times/min. NOTE

1 In this document, such environments are referred to as critical care environments. High-frequency ventilators used in such environments are considered life-sustaining equipment. NOTE

2 For the purposes of this document, such high-frequency ventilators are capable of providing transport within a specialized medical facility (e.g., as a ventilator that can be operated during transport). NOTE 3: High-frequency ventilators used for transport within a specialized healthcare setting are not considered ventilators for use in an emergency medical services setting.

Note 4: There are three main names for HFV.

---High frequency percussion ventilation (HFPV, typical HFV frequency is 60 times/min~1000 times/min);

--- High frequency jet ventilation (HFJV, typical HFV frequency is 100 times/min~1500 times/min); and

---High frequency oscillatory ventilation (HFOV, typical HFV frequency is 180 times/min~1200 times/min, usually with an active expiratory phase). In addition, the nomenclature of HFV may be combined or used in conjunction with ventilators with a ventilation rate of less than 150 breaths/min. *A high-frequency ventilator is not considered a physiological closed-loop control system unless it uses patient physiological variables to adjust ventilation therapy settings. This document also applies to accessories that the manufacturer intends to be connected to a HFV breathing system or high-frequency ventilator and whose characteristics may affect Affect the basic safety or basic performance of the high-frequency ventilator. If a chapter or clause explicitly states that it applies only to ME EQUIPMENT or only to ME SYSTEMS, the title and the body of the chapter or clause will state this. If not explicitly stated, the relevant clause or subclause applies to both ME EQUIPMENT and ME SYSTEMS. In addition to 7.2.13 and 8.4.1 of the general standard, the intended physiological effects of ME EQUIPMENT or ME SYSTEMS within the scope of this document shall result in Hazards There are no specific requirements in this document. NOTE 5: For additional information, see 4.2 of the general standard. This document does not apply to.

--- ME EQUIPMENT intended only to enhance the ventilation of spontaneously breathing patients in professional healthcare settings;

---Non-high frequency ventilators and their accessories for routine ventilation in critical care environments; NOTE 6 HFV may include conventional critical care ventilator operating modes, in which case GB 9706.212-2020 applies to these modes.

---Anesthetic ventilators and their accessories;

--- Ventilators and their accessories for use in emergency medical services environments; NOTE 7: HFV may include the functionality of an EMS ventilator.

--- Home ventilators and their accessories that rely on patient ventilators;

--- Respiratory support equipment and accessories for respiratory dysfunction and respiratory insufficiency;

1 Scope

YY 9706.287 is the particular standard for the high-frequency ventilator, the machine that ventilates with very small volumes delivered at rates far above normal breathing, used mainly in neonatal and rescue ventilation when conventional ventilation would injure the lung. It specifies the basic safety and essential performance requirements for high-frequency ventilators used together with their accessories. It belongs to the YY 9706 series, the Chinese adoption of the IEC 60601 family, and as a YY standard without the /T suffix compliance is mandatory. At 47,500 words it is one of the longest particular standards in the series. The 2025 edition takes effect on 1 March 2028. For a manufacturer or an importer of HFOV or high-frequency jet ventilators for China, this is the governing document.
