SLAC ACUTE SHORTAGE VENITILATOR

Background

We have designed a functional ventilator that can be built with readily available parts.  The total cost of the parts is under $400, and we have tested that the device meets the Association for the Advancement of Medical Instrumentation (AAMI) Emergency Use Resuscitator System (EURS) design guidance specifications (AAMI/CR503:2020) for simplified ventilator designs.



Support

This project was supported by the Department of Energy Office of Science through the National Virtual Biotechnology Laboratory, a consortium of DOE national laboratories focused on response to COVID-19, and through Stanford University discretionary funds allocated to SLAC National Accelerator Laboratory: details.

 

Seeking Partners
We are working with the Stanford Office of Technology Licensing (OTL) to identify partners to produce and distribute ventilators based on our design: details.

Ventilator Design

Our ventilator design uses  bag valve mask that is compressed by a
hinged paddle driven by a pneumatic cylinder which is controlled by an Arduino microcontroller.


The system can run autonomously, although a serialized data stream is available for monitoring
the patient pressure and flow.

We also proive a graphical interface for control and monitoring that can run on  any Windows computer.

In this video, team member sander Breur describes the Acute Shortage Ventilator Project and how the team tested our prototype device.
