The Macau Institute of Development and Quality and the University of Macau have established a close cooperative relationship since 1997 , assisting each other in applied engineering research, high-tech research and application, and testing technology development. The emergence of COVID- 19 at the end of 2019 has disrupted the order of the entire world, and medical supplies have become extremely important. Because of the current epidemic, the Institute has set the research and development of medical equipment as one of its development priorities. When the University of Macau contacted the Institute and hoped that the Institute would develop ventilators to support friends in Africa, the Institute was very happy to have this opportunity to contribute. The research institute uses the 3R design spirit, namely Reliable , Repeatable and Reproducible . The ventilator must be stable, the function must be repeatable, and at the same time, it can be reproduced. The design goal is to manufacture medical-grade ventilators in Macau.

The Macau Institute of Development and Quality is responsible for the design of the entire machine, including the mechanical structure, pneumatic circuits, electronic circuits, controller working methods, system software and hardware integration and support for all research funds. Many major components are completed using CAD/CAM and 3D printing technologies , to facilitate replication production, eliminate high-cost molding or machining processes, analog and mixed-signal VLSI . The State Key Laboratory is responsible for optimizing the circuit and making it into a PCB board to reduce cost and volume. The Intelligence and Micro-Nano Systems Laboratory of the Department of Mechatronics is responsible for programming the working principle of the controller in Python to make mechanical control more reliable and resilient. The ventilator now has an isobaric and isovolume breathing assistance mode. Medical staff can change the parameters of the air supply through the touch screen at any time according to the patient's condition. At the same time, they can also use a portable device to change and monitor the working condition of the ventilator. In addition, the machine has reserved space for collecting 35 sets of digital signals and upgrading the control software, allowing the machine to reserve space for sustainable development.

Since the concept of the design is to help African countries produce ventilators, our work will not end after donation, but there will be more interactions, including training African friends to use and manufacture ventilators, and investing more research efforts to make breathing function to help patients more effectively.

This ventilator embodies the spirit of industry-university-research, which is exactly what Macau needs. In the future, the cooperation with UM will continue to deepen. At the same time, the friendly cooperation with African countries has also opened a door for the Macau Institute of Development and Quality, allowing us to go out of Macau in addition to serving Macau.
