Cavitation — the formation and collapse of vapor bubbles within a fluid — poses a significant risk to blood-contacting medical devices. In blood pumps, uncontrolled cavitation can lead to mechanical damage, reduced efficiency, and hemolysis, ultimately compromising patient safety. Precise cavitation testing is therefore essential to validate device performance under clinically relevant operating conditions.
At our laboratory, we conduct cavitation assessments in strict accordance with ISO 18242, the international standard for evaluating extracorporeal blood-contacting devices. This framework ensures:
- Standardized Methodology:
Controlled test environments that replicate physiological flow and pressure conditions as per customer requirements. - Performance Validation:
Measurement of cavitation onset, bubble dynamics, and their impact on pump performance. - Safety Assurance:
Verification of operating ranges where the occurrence of cavitation is excluded. - Regulatory Compliance:
Documentation aligned with ISO 18242 requirements to support global submissions and approvals.
- Advanced Instrumentation:
High-resolution flow visualization and monitoring (sensor-based bubble counting) for precise cavitation detection. - Expert Analysis:
Detailed reporting that translates technical findings into actionable design improvements. - Accelerated Development:
Early identification of cavitation risks reduces costly redesigns and shortens time-to-market.
By combining technical expertise with ISO-based testing methods, we help manufacturers demonstrate the reliability and safety of their blood pumps. Partnering with us means confidence in compliance, innovation, and patient protection.
