Two design tools that will allow you to explore different gear configurations and select appropriate motors: CAD files: Zip file (with help from Neal Drapeau).Please note the Terms of Use and that we do not have the human resources to provide technical support. This is essential to ensure patient safety. Our code is NOT approved by any regulatory body to operate a medical device.Ĭaution: Any group working to develop ventilation or other medical device must conduct significant hardware and software validation and testing to identify and mitigate fault conditions. Our code is specific to an Arduino Mega, RoboClaw and DC motor. (Synchronizing with a human is non-trivial.) These features are only a baseline and others will likely wish to add more safeties and features. Assist control, to detect patient breathing, is implemented, but is still a work in progress. Our goal is to help others understand the function of our Version 3 prototype system, with regards to: delivering tidal volumes, breaths per minute and I:E ratios visible and audible alarm functions and the display operation. This code is provided for reference use only. Updated 28 April 2020 By downloading material I agree and acknowledge that I have read and agree to the Terms of Use.
