Introduction of YY 9706.112-2021

1 Scope, object and related standards 1.1 * Scope This collateral standard applies to the basic safety and essential performance of medical electrical equipment and medical electrical systems, hereafter referred to as ME equipment and ME systems, which are intended for use in the emergency medical services environment. This collateral standard is applicable to ME equipment and ME systems which are intended, as indicated in the instructions for use by their manufacturer, for use in the emergency medical services environment (hereinafter referred to as EMS environment). Note 1: For the purposes of this standard, the intent of the manufacturer is indicated in the instructions for use. The responsible organization and the operator need to be aware that any other use outside the manufacturer’s intended use can result in a hazardous situation for the patient. The EMS environment includes: ——responding to and providing life support at the scene of an emergency to a patient reported as experiencing injury or illness in a pre-hospital setting, and transporting the patient, while continuing such life support care, to an appropriate professional healthcare facility for further care. ——providing monitoring, treatment or diagnosis during transport between professional healthcare facilities. This collateral standard does not apply to ME equipment and ME systems intended solely for use in the home healthcare environment covered by YY 9706.111 or solely for use in professional healthcare facilities covered by GB 9706.1 without the additions of YY 9706.111 or this collateral standard. ME equipment and ME systems are often not solely intended for one environment. Such ME equipment or ME system can be intended for multiple use environments, and as such, if also intended for use in the EMS environment, are within the scope of this standard. Example: ME equipment or ME system intended for both the EMS environment and the professional healthcare facility environment. Note 2: EMS environment ME equipment and ME systems can be used in locations with unreliable electrical sources and outdoor environmental conditions. Note 3: The rationale about clauses and subclauses with asterisk (*) in this collateral standard are indicated in Annex A. 1.2 * Object The object of this collateral standard is to provide general requirements for ME equipment and ME systems carried to the scene of an emergency and used there, as well as in transport, in situations where the ambient conditions differ from indoor conditions. The object of this collateral standard is to specify general requirements that are in addition to those of the general standard and to serve as the basis for particular standards. 1.3 Related standards 1.3.1 GB 9706.1 For ME equipment and ME systems, this collateral standard complements GB 9706.1, hereafter referred to as the general standard. When referring to GB 9706.1 or to this collateral standard, either individually or in combination, the following conventions are used: ——“the general standard” designates GB 9706.1 alone; ——“this collateral standard” designates YY 9706.112 alone (IEC 60601-1-12); ——“this standard” designates the combination of the general standard and this collateral standard. 1.3.2 Particular standards A requirement in a particular standard takes priority over the corresponding requirement in this collateral standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
