Full title and description

IEC TR 60601-4-1:2017 — Medical electrical equipment — Part 4-1: Guidance and interpretation — Medical electrical equipment and medical electrical systems employing a degree of autonomy. This technical report gives manufacturers and standards writers guidance on defining and classifying “degree of autonomy” (DOA) for medical electrical equipment (MEE) and medical electrical systems (MES), and on applying risk management and usability engineering where autonomous functions affect basic safety and essential performance.

Abstract

IEC TR 60601-4-1:2017 helps manufacturers through decisions and steps for detailed risk management and usability engineering for MEE/MES that employ a degree of autonomy (DOA). The report defines DOA and medical robot terminology, describes methodologies to determine DOA, addresses the relationship between DOA and risk, and provides guidance to support compliance with IEC 60601-1 and its amendment. Informative annexes provide exemplar classification methods and worked examples (exoskeletons, surgical robots, closed‑loop systems, AEDs, image‑guided radiotherapy).

Scope

Provides guidance and interpretation to support application of basic safety and essential performance requirements to MEE and MES that include autonomous behaviours. Covers methods to determine and classify degree of autonomy, how DOA influences the risk management process and usability engineering, interactions with software lifecycle and programmable electrical medical systems (PEMS), and considerations for distributed systems and IT networks incorporating medical devices. The report is intended to support compliance with IEC 60601‑1:2005 and IEC 60601‑1:2005/AMD1:2012 and to assist standards writers.

Key topics and requirements

• Definition and classification of Degree of Autonomy (DOA) for MEE/MES; distinction between medical robots and other devices.
• Methodologies to assess DOA (descriptive, binary, weighted approaches) and exemplar classification methods in annexes.
• Integration of DOA into risk management (ISO 14971 concepts) and the risk‑control hierarchy for autonomous functions.
• Usability engineering considerations for increased DOA — operator situation awareness, reaction time, detectability of faults and human‑machine interactions.
• Interaction with software lifecycle standards (PEMS and IEC 62304), and guidance for distributed systems, IT‑networks and interoperability within MES.
• Considerations of basic safety and essential performance where autonomy affects clinical decisions or actuation (including physiologic closed‑loop control examples).
• Informative worked examples and case studies (exoskeletons, robotically assisted surgery, image‑guided radiotherapy, AEDs) to illustrate DOA effects on risk management.

Typical use and users

Primary users are medical device manufacturers (design, software, risk management and human factors teams) integrating autonomous functions; regulatory and compliance engineers assessing safety and essential performance; notified bodies and test laboratories; and standards committees developing requirements for MEE/MES with autonomy. The report is also used by architects and system engineers working on networked medical systems and closed‑loop therapeutic devices.

Related standards

Commonly referenced standards and guidance include IEC 60601‑1 (basic safety and essential performance), IEC 62304 (medical device software — software lifecycle), IEC 62366‑1 (usability engineering), ISO 14971 (risk management for medical devices), and IEC 80001‑1 (risk management for IT‑networks incorporating medical devices). The report is intended to align terminology and concepts of DOA across IEC/ISO standards.
