Why leak testing is critical in medical devices
Leak testing ensures that medical devices are sealed correctly and free from contamination risks, supporting patient safety and regulatory compliance.
Regulatory context
Medical device manufacturers must comply with:
- FDA requirements
- ISO standards
- CE marking regulations
Leak testing is often part of validated production processes (IQ/OQ/PQ).
Common medical applications
Leak testing is used for:
- Syringes and infusion systems
- Catheters and tubing
- Implantable devices
- Sterile packaging
Key requirements in medical leak testing
Medical applications require:
- High sensitivity (micro-leak detection)
- Repeatability and traceability
- Data logging for audits
- Non-destructive testing methods
Common challenges
- Very small allowable leak rates
- Strict validation requirements
- Sensitivity to environmental variation
Technology used
Typical systems include:
- Pressure decay
- Mass flow testing
- Vacuum decay
- Automated inline testing systems
