Defibrillator Battery Management Unit
about project
Primedic required a comprehensive verification process, including automated testing and certification documentation preparation for their defibrillator’s battery management unit software.
As a Class III medical device, the defibrillator had stringent requirements for reliability and compliance with the highest industry standards, specifically IEC 62304 and ISO 13485.
The key challenge was ensuring that the battery management system could operate autonomously for three years while maintaining optimal functionality. The defibrillator’s battery condition is critical; any failure could result in incorrect treatment during emergencies.
tasks
Perform software verification to ensure the software meets the high reliability and safety standards required for a IEC 62304 Class C medical device.
Develop and execute automated tests to validate the functionality, accuracy, and safety of the defibrillator’s battery management system.
Prepare certification documents in compliance with industry standards, including IEC 62304 and ISO 13485, ensuring the software meets regulatory requirements.
Ensure that the defibrillator operates with precise functionality and maintains safety standards over an extended period (autonomously for up to 3 years).

process
Project Implementation
Requirement Capturing and Reviews
The team collaborated with the client to capture detailed software requirements from existing code and high-level descriptions. These requirements were then reviewed to ensure they aligned with IEC 62304 and ISO 13485 standards.
Code Reviews and Analysis
Code reviews were conducted to evaluate the software’s quality and compliance with safety standards. This phase also included analyzing the software’s structure to identify areas needing further improvement.
Automated Testing Implementation
Automated tests were developed and implemented to validate the software’s functionality, reliability, and performance. The testing was designed to cover all critical paths required for a Class III medical device.
Structural Coverage Analysis
The team measured and analyzed code coverage to ensure that the automated tests provided comprehensive verification, meeting regulatory requirements for structural coverage.
Bug Fixing and Iterations
Over 50 issues were identified during testing, including 10 critical bugs. The team addressed these through multiple iterations, refining the software until it met the necessary safety and performance criteria.
Certification Documentation
The final phase involved preparing the necessary documentation for IEC 62304 and ISO 13485 compliance, enabling the client to successfully obtain CE certification for the defibrillator.
