CSA Group Medical electrical equipment - Part 4-1: Guidance and interpretation - Medical electrical equipment and medical electrical systems employing a degree of autonomy IEC/TR 60601-4-1:2017

IEC TR 60601-4-1:2017(E) is intended to help a manufacturer through the key decisions and steps to be taken to perform a detailed risk management and usability engineering processes for medical electrical equipment or a medical electrical system, hereafter referred to as MEE or MES, employing a degree of autonomy (DOA).This document provides a definition of DOA of MEE or MES and a medical robot, and also provides guidance on:- methodologies to perform the risk management process and usability engineering for an MEE or MES with a DOA;- considerations of basic safety and essential performance for an MEE and MES with a DOA; and- identifying the use of DOA, and similar concepts in existing ISO/IEC standards dealing with MEE or MES with the goal to facilitate alignment of standards by consistent use of the concept of DOA; and- distinguishing between medical robots, and other MEE and MES.Unless specified otherwise, this document considers MEE and MES together.The manufacturer of an MEE or MES with a DOA is expected to design and manufacture an MEE or MES that fulfils its intended use and does not have unacceptable risk throughout its life-cycle.This document provides guidance to help the manufacturer in complying with the requirements of IEC 60601-1:2005 and IEC 60601-1:2005/AMD1:20 12 for MEE and MES with DOA. The document is also intended as guidance for future standard writers.There are no prerequisites to this document.
