Study Notes
Design Principles and Regulations
- IEC/EN 60601 standard focuses on safety and effectiveness for medical electrical instruments; first published in 1977.
- Comprises IEC/EN 60601-1 (general part), collateral sections, and vertical standards for specific medical devices.
- Risk analysis is essential during the design phase to identify potential hazards affecting patients and operators.
- Introduces control measures for harm through:
- Prevention measures to reduce occurrence probability.
- Protection measures to mitigate severity of harm.
- Risk analysis results are often represented in an 'acceptability matrix'.
General Design System Model
- Medical instruments are designed within a structured system architecture, ensuring systematic approach to development.
Pressure and Flow Instruments
- Specific designs like pressure measurement modules illustrate the engineering of biomedical devices.
Biopotential Instruments
- Electroencephalographs (EEGs) and electromyographs (EMGs) represent critical biopotential instruments for monitoring electrical activities in the brain and muscles, respectively.
- Conceptual designs include single-channel schemes for EEGs and instrumentation amplifiers for EMG recordings.
The Design Process
- Adopting a design process enhances product quality, minimizes risks, and lowers the likelihood of costly rework.
- Risk management components include:
- Risk analysis: Identify hazards and assess their severity and probability.
- Risk evaluation: Determine risk acceptability and protective measures necessity.
- Risk control: Implement measures for unacceptable risks.
- Risk monitoring: Regularly assess risks for changes or new factors.
- Comprehensive documentation in 'risk management files' is maintained for each product, containing all relevant records.
Post-Production Monitoring
- Post-production information should identify:
- Newly recognized hazards.
- Changes in the acceptability of estimated risks.
- Invalidation of original assessments when necessary.
- The risk management file is updated under various conditions, such as:
- New legislation or scientific evidence supporting better risk reduction methods.
- Introduction of new technologies or changes in materials and suppliers.
- Documented complaints and accidents or 'near misses'.
