Overview
ISO 16571:2024/Amd 1:2026 – Systems for Evacuation of Plume Generated by Medical Devices is an important amendment to the international standard that addresses the enhancement of safety features, definitions, and performance criteria for plume evacuation systems (PES) used in healthcare environments. This amendment, developed by the ISO Technical Committee 121, Subcommittee 6 (ISO/TC 121/SC 6), in collaboration with relevant European standardization bodies, strengthens requirements to ensure the effectiveness of systems designed to control and remove surgical plume generated by medical devices.
Surgical plume, consisting of gaseous by-products produced during medical procedures (such as laser surgery or electrosurgery), poses risks to patient safety and occupational health. This amendment updates system definitions, technical requirements, and test methods, ensuring that medical device manufacturers, healthcare providers, and facility managers can implement improved plume management solutions.
Key Topics
- Updated Definitions: Adjustments to terminology and the scope of components such as capture devices and filtration systems, improving clarity for manufacturers and users.
- Filtration Requirements: Enhanced criteria for particulate filter assemblies, mandating the use of ultra-low penetration air (ULPA) filters meeting ISO 29463-1:2024 standards, ensuring optimal plume filtration performance.
- Venturi Usage: Specification that venturis in PES must not be driven by medical gases if gas flow exceeds 20 l/min, mitigating risks to medical gas supply infrastructure.
- Noise Testing: Clear guidelines for evaluating noise generated by the flow-generator and filtration subsystems to address occupational safety and comfort.
- Integrated Component Testing: Clarification that performance testing requirements apply specifically to the PES component when integrated into multi-function medical devices.
- Source Requirements: Stipulation that the vacuum source for active PES must meet defined system requirements, whether it is stationary, mobile, or pipeline-based.
- Plume Particle Concentration: Research-backed limits on particle concentration in monopolar and bipolar electrosurgery plume, aiding risk assessment for exposure.
Applications
- Healthcare Facilities: Assists hospitals, surgical centers, and clinics in selecting and maintaining compliant plume evacuation systems, ensuring a safer environment for patients and staff.
- Medical Device Manufacturers: Provides clear requirements for the design, testing, and integration of plume evacuation subsystems in new medical equipment.
- Occupational Safety: Enhances efforts to control airborne contaminants in operating rooms, reducing health risks associated with surgical smoke for clinical staff.
- Regulatory Compliance: Facilitates adherence to national and international safety regulations, supporting procurement and installation of certified plume evacuation solutions.
