第三节 超声设备的检验标准

一、超声设备的国际标准化组织

国际标准化组织(ISO)、国际电工委员会(IEC)和国际电信联盟(ITU)是世界三大知名的国际标准化组织,它们以及其他国际性标准化组织确认并公布的标准称为国际标准。其中,IEC是医用电气领域最重要的标准化组织之一,主要负责起草和发布电工、电子和相关技术领域的国际标准。[1-8]

IEC负责医用超声设备相关标准化工作的部门是超声波技术委员会(编号IEC/TC87)。其主要负责制定与超声波领域相关的设备和系统的特性、测量方法、安全和规范等标准,提供了与医用超声设备相关的IS(国际标准)、TS(技术条件)和TR(技术报告),涉及术语和定义、测量方法步骤、测量手段技术要求、产品技术要求等。[1-9]

医用超声设备相关现行国际标准主要有:

(1)IEC 60601-2-5:2009 Medical eletrical equipment—Part 2-5:Particular require-ments for the basic safety and essential performance of ultrasonic physiotherapy equipment;

(2)IEC 60601-2-37:2007+AMD1:2015 Medical electrical equipment—Part 2-37:Particular requirements for the basic safety and essential performance of ultrasonic medical diag-nostic and monitoring equipment;

(3)IEC 60601-2-62:2013 Medical electrical equipment—Part 2-62:Particular re-quirements for the basic safety and essential performance of high intensity therapeutic ultrasound (HITU)equipment;

(4)IEC 61161:2013 Ultrasonics—Power measurement-Radiation force balances and per-formance requirements;

(5)IEC 61266:1994 Ultrasonics—Hand-held probe Doppler foetal heartbeat detectors—Performance requirements and methods of measurement and reporting;

(6)IEC 61391-1:2006+AMD1:2017 Ultrasonics—Pulse-echo scanners—Part 1:Techniques for calibrating spatial measurement systems and measurement of point-spread function response;

(7)IEC 61391-2:2010 Ultrasonics—Pulse-echo scanners—Part 2: Measurement of maximum depth of penetration and local dynamic range;

(8)IEC 61685:2001 Ultrasonics—Flow measurement systems—Flow test object;

(9)IEC 61689:2022 Ultrasonics—Physiotherapy systems—Field specifications and meth-ods of measurement in the frequency range 0,5 MHz to 5 MHz;

(10)IEC 62127-1:2022 Ultrasonics—Hydrophones—Part 1:Measurement and charac-terization of medical ultrasonic fields;

(11)IEC 62555:2013 Ultrasonics—Power measurement—High intensity therapeutic ultra-sound(HITU)transducers and systems。
