AutoLung Respiratory Assistance Device


Low and Middle Income Countries lack access to mechanical ventilation. AutoLung addresses this issue with its Respiratory Assistance Device. The AutoLung device is an open source ventilator alternative that can be built by anyone in five hours using free online instructions and cheap commodity hardware.

I designed the mechanism for the AutoLung Respiratory Assistance Device. I built several prototypes for different mechanism options, then selected the best mechanism option, a slider crank linkage.

I created a detailed model for the selected design and constructed the design using hand tools.

I created drawings for the device mechanical components, and wrote build instructions for all elements of the device (mechanical and electrical).

I constructed the full device including the mechanism, electronics, enclosure, and the tubing/air delivery system. I wrote Arduino code to operate sensors, and implemented sensors. I participated in writing code for device controls. I designed test processes and conducted tests on the AutoLung device, then performed data analysis on the test results.
