Overview
EN ISO 10079-3:2022 - Medical suction equipment - Part 3: Suction equipment powered from a vacuum or positive pressure gas source (ISO 10079-3:2022) - specifies basic safety and performance requirements for medical suction devices that generate venturi suction from a vacuum or positive-pressure gas source. The standard covers suction equipment connected to medical gas pipeline systems or cylinders, including venturi attachments, whether they are standalone devices or part of an integrated system.
Key topics and requirements
- Scope and intent
- Applies specifically to suction equipment powered from a vacuum or a positive-pressure gas source that produces venturi suction.
- Reference to general requirements
- Many general requirements (materials, design, performance, manufacturer information) are handled by ISO 10079-4:2021; EN ISO 10079-3:2022 references these clauses rather than repeating them.
- Supply connections
- If designed for direct connection to a medical gas pipeline terminal or pressure regulator outlet, the equipment must be fitted with a probe complying with the relevant national standard.
- If designed for remote connection, a low‑pressure hose assembly complying with ISO 5359 must be used.
- Conformance of supply connections is verified by inspection.
- Performance, safety and field use
- Performance, materials, design and additional/alternative requirements for field use or transport use follow the clauses specified in ISO 10079-4:2021.
- Documentation
- Manufacturer-supplied information requirements are specified by reference to ISO 10079-4.
Practical applications
- Medical device manufacturers designing or certifying venturi-powered suction units for hospitals, clinics, ambulances, or field deployment.
- Clinical engineers and biomedical maintenance teams verifying that suction equipment complies with mandated safety and connection requirements before installation on medical gas pipeline systems or cylinder outlets.
- Procurement and regulatory professionals evaluating product compliance for purchase, certification, or national standard adoption.
- Designers of integrated operating-room or emergency-care systems that incorporate venturi suction modules.
Who should use this standard
- Manufacturers of medical suction equipment and venturi attachments
- Biomedical engineers and maintenance technicians
- Hospital procurement and compliance officers
- Test labs and conformity assessment bodies
- Regulators and national standards organizations
