Calling all doctors, nurses, designers, engineers and designers…

Join one of the amazing Open Source Ventilator Projects to contribute your passion, creativity, time and expertise to help develop low-cost ventilators to fight the Coronavirus (COVID-19). Here are some ways of getting involved and some inspiration and some cheaper ventilator options:

1. 13,000+ member Open Source Coronavirus Supplies group on Slack
2. OPEN CALL closes 24 March at 9:00 GMT: Rapidly Manufactured Ventilated Systems
3. March 19-20 University College London (UCL) Design & Refine Sprint Low Cost Ventilators — Register Now
4. Ultimate Medical Hackathon
5. Open Source COVID19 Medical Supplies group on Facebook
6. DIY Pandemic Ventilator (built during Avian Flu crisis and shared on Instructables)
7. Story on OneBreath winning PopSci Innovation Award in 2010
8. OneBreath company web site ($4,000 low cost respirator vs. $35,000 traditional solution)
9. $500 pandemic ventilator from Canada
10. Open Respirator Project on Github

Here is a video showing a DIY ventilator solution:

And here is a video from vacuum manufacturer Gtech in the United Kingdom (UK) showing a prototype they are working on to be entirely powered by the hospital oxygen supply in as simple a way as possible so they can hopefully meet the UK government’s call to make 30,000 ventilators in two weeks:

Just added another video highlighting an improvised design experiment the University of Minnesota is working on with some design partners:

The design team has made all of their designs shown in the University of Minnesota video – open source and available by clicking this REDDIT link

Here is an open source ventilator project out of Germany – The CORESPONSE – COvid19 RESPirator (Open Source):

Cost is about 75 Euros per unit and all of the details of this 3D printed open source project are available by clicking here.

Here is an article (click here) and a video detailing how to turn a snorkeling mask into a non-invasive ventilator:

AgVa Healthcare has produced a low cost ventilator starting at under $700 (according to the video) that leverages an app on the user’s smartphone to control its functions. Another great example of Indian ingenuity that was originally submitted as a comment on this article:

Below is a video from the Lemelson Foundation from 2015 that shares the story of how Matt Callaghan came to start OneBreath Ventilators to create lower cost ventilators for developing countries and the rest of the world after H1N1 Swine Flu never became a problem in the USA thanks to President Obama’s administration proactive steps to protect our country. (Learn more about the design process by reading this Stanford Byers Center for BioDesign article)

UPDATE: Just found this video showing how to use one ventilator to save FOUR people – video from the United States’ Center for Disease Control (CDC) – all the details health professionals might need:

CAUTION, this from a doctor in Italy about risks of co-ventilating to be kept in mind as you group people to co-ventilate in a crisis situation:

“This is unfortunately not as good of an idea as it seems. In trauma and shootings, it’s one thing because lung compliance is unlikely to change quickly. However, in ARDS (and COVID19), we expect to have dramatic changes in lung compliance. When one patients lung compliance changes, there is a significant risk of underventilating the patient with lowest compliance and overventilating patients with highest compliance – both potentially deadly. I worry that instead of saving one person, you create a situation where you increase the odds of losing both (or all 4) patients“

BUT, according to Alexander Clarke you can solve this problem with flow restrictors…

Another article detailing previous research and considerations – https://www.saasceo.com/ventilator-capacity/

VESper™ is a unique ventilator expansion device that allows a single ventilator to support up to four patients under emergency use authorization by the FDA during times of acute equipment shortages such as the current COVID-19 pandemic.

Hospitals can apply to receive the free source code and printing specifications for the device, produced using 3D printing technology, the device is developed with material already in use for medical devices and produced at minimal cost:

• designed to work with ISO standard respiratory connections;
• allows for appropriate filtering of bacteria and viruses in the ventilator tubing;
• does not impact the care of other patients connected to the same machine.

Here is a video showing how to make your own reusable elastomeric respirator (click here for instrutions poster):

And here is a video discussing whether people should wear face masks and how people can use DIY face masks without impacting availability of N95 and surgical masks to healthcare workers:

Here is a video showing how to make face masks to help healthcare workers:

AND here is a link to a PDF of the pattern to make the masks – https://courierpressblogs.com/pdf/howtomakeafacemask.pdf

Here is how to make a DIY Personal Protective Equipment (PPE) smock out of a garbage bag thanks to the people at Hefty:

Doctors and Nurses in Spain and other countries are already having to do this.

And, here is a picture of an ingenious idea of using a headband and buttons to save the ears of healthcare workers from chafing of wearing a mask 13-14 hours a day. Thanks Natasha Smith!

And, here is an interesting article about a surgical and N95 mask design that uses salt to help kill viruses like Coronavirus (COVID-19) on masks to improve their effectiveness in protecting the wearer against getting sick
