A hardware–software medical device project combining embedded systems, fluid mechanics, and intelligent control to assist healthcare professionals with safe and efficient wound irrigation.
The (Pulse Lavage) project was a medical engineering initiative to design a device capable of performing controlled, pulsed irrigation for wound care. Traditional manual lavage techniques often lack consistency, efficiency, and safety controls. Our mission was to deliver a smart solution that medical professionals could trust in clinical settings.
Medical devices face unique challenges:
Precision & Control: Delivering pulsed fluid at consistent pressure and volume while remaining safe for delicate tissue.
Hardware Integration: Combining sensors, pumps, valves, and microcontrollers in a compact, reliable unit.
Compliance & Safety: Designing within the strict requirements of healthcare regulations and standards.
User Experience: Ensuring doctors and nurses could operate the device easily, without technical barriers.
Our team at Hippogriff engineered a fully functional prototype that integrated:
Embedded Control: Built with Arduino/ESP32 for real-time control of pump motors, fluid delivery, and feedback loops.
Sensor Feedback: Pressure and flow sensors to regulate lavage delivery dynamically.
UI/UX Layer: A simple interface with start/stop, pressure adjustment, and safety lockout features.
Data & Connectivity: Optional logging of usage data and potential for integration with hospital systems.
The mechanical design was paired with robust firmware to ensure safety and consistency. Security and redundancy were built into the hardware-software interaction to prevent malfunction in critical scenarios.
The result was a working smart pulse lavage device that demonstrated:
🚀 Improved consistency in wound irrigation compared to manual techniques.
🔒 Safer operation, reducing risks of over-pressure or fluid mismanagement.
🎯 Ease of use, enabling healthcare providers to operate it with minimal training.
🌍 A scalable foundation, ready for future iterations toward clinical certification.
This project showcased Hippogriff’s strength in medical IoT, embedded systems, and cross-disciplinary engineering, bridging the gap between healthcare and technology.
