Overview
IEC 60601-2-75:2017 is an international standard that specifies the particular requirements for the basic safety and essential performance of photodynamic therapy (PDT) and photodynamic diagnosis (PDD) medical electrical equipment. Developed by the International Electrotechnical Commission (IEC), this standard ensures that PDT and PDD devices are safe and effective for use in compensating or alleviating disease, injury, or disability.
Photodynamic therapy and diagnosis involve the use of photosensitizers activated by specific wavelengths of light, targeting diseased tissue for treatment or diagnostic purposes. IEC 60601-2-75 complements the general medical electrical equipment standards, particularly IEC 60601-1:2005 and its Amendment 1, to cover unique hazards and performance criteria associated with photodynamic applications.
Key Topics
-
Scope and Application
The standard applies exclusively to photodynamic therapy and diagnosis equipment. It excludes devices used for photothermal ablation, coagulation, hyperthermia, low-level laser therapies without photosensitizers, and illumination equipment intended only for observation or monitoring.
-
Safety and Performance Requirements
IEC 60601-2-75 addresses the basic safety principles and essential performance metrics required for photodynamic devices, including electrical safety, mechanical safety, radiation hazards, temperature controls, and accuracy of device controls.
-
Hazard Protection
The standard outlines protection methods against:
- Electrical hazards derived from medical electrical equipment (ME EQUIPMENT) and medical electrical systems (ME SYSTEMS)
- Mechanical hazards caused by device components
- Excessive or unwanted radiation exposure inherent in photodynamic processes
- Overheating and other operational hazards
-
Device Identification and Documentation
Requirements for clear identification, marking, and supporting documents ensure proper usage and traceability of PDT and PDD equipment.
-
Programmable Electrical Medical Systems (PEMS)
Special attention is given to the safety and performance of programmable features in photodynamic devices to mitigate risk during automated or user-programmed operations.
-
Risk Assessment Guidance
Informative annexes offer detailed guidance on risk assessment tailored to photodynamic therapy and diagnosis equipment, identifying hazardous situations and providing rationale to support manufacturers and regulators.
Applications
IEC 60601-2-75:2017 serves as a crucial resource in the medical device industry for designing, testing, and certifying photodynamic therapy and diagnosis equipment. Its practical applications include:
