IEC 62366-1
Medical devices, Part 1: Application of usability engineering to medical devices
In plain words
What it covers.
The standard for designing devices that are safe to use by real people in real settings. The manufacturer studies who the users are, where they work and what tasks they do, finds use errors that could cause harm, designs the interface to prevent them and proves it with a summative evaluation with representative users.
Who uses it: Device designers and human factors engineers; clinical engineers judging usability in procurement and investigations.
A summary written by BMEssentia for learning, not the text of the standard. Always work from the current official edition and the manufacturer's instructions.
It covers
- Use specification (users, environment, tasks)
- User interface characteristics related to safety
- Known use problems
- Hazard-related use scenarios
- Formative evaluation
- Summative evaluation
- Usability engineering file
Key points
What engineers need to know.
- A use error is an action or lack of action that leads to a result the user or maker did not intend.
- Use errors are often design problems: blaming the user does not remove the hazard.
- Formative tests shape the design; the summative test proves it is safe to use.
- Summative tests use representative users doing hazard-related tasks.
- Training and labelling count as weak controls under ISO 14971.
- Similar-looking connectors, confusing units and hidden modes are classic use-error traps.
