Ventilators

As of November 2020 this challenge was met. The lesson here is that the same focus if applied to the Return to Life challenge would stop the virus spread and save lives. As of November 2020 that has not yet happened. All research has been focused on the Return to Life need.

The big companies mobilize: Ford . GM we wish them well but we will still need the SMBs.

SMB Manufactures Ready To Start Now

  1. Bloom Energy . Retooled to repair ventilators
  2. Sea Long Medical Systems Bubble Helmet and other Solutions . Product Brochure . modified to hook into hospital oxygen supply . The helmets were originally designed to run through ventilators, but with the help of Dr. Bhakti Patel, a pulmonologist at the University of Chicago and her mentor, Dr. John Kress, the company has modified them to be hooked up to a hospital’s regular oxygen supply. The team also added a viral filter to avoid exposing others to COVID-19.

Robertson Ventilator: Low Tech approach easily sourced and built. University of Mississippi Medical Center makeshift ventilator with supplies found at a hardware store. Dr. Charles Robertson, a UMMC pediatric anesthesiologist, to make the "absolute simplest ventilator we can build with parts available in any city, you don't need special tools to put together and can be done quickly as the need arises. Made with a garden hose, lamp timer and electronic valve, the ventilator, named the Robertson Ventilator, for less than $100, can be assembled in approximately 20 to 30 minutes, meaning a dedicated team of four to five could produce nearly 100 in a day if needed.

CassBeth Ventilator Architecture Alternatives

  1. Architecture A: High Tech - that is what is available now but unable to fill the need (probably all stocks purchased by elite buyers - no gov oversight)
  2. Architecture B: Middle Tech - most functions stripped out but electronic with circuit boards and chips
  3. Architecture C: Low Tech - electrical no circuit boards maybe just relays or power transistors, with a few caps and resistors, and solenoids
  4. Architecture D: Mechanical Tech - purely mechanical approach rotating wheel in an intake / exhaust valve body perhaps via 3D printing
  5. Architecture E: Helmet Ventilators - The idea is to use a central "air pump control subsystem" service multiple patients that are fitted with a plastic helmet. So perhaps only a few thousand pump subsystems are needed, while the hundreds of thousands of helmets and hose assemblies that would be needed are easier to produce in the time that they are needed. This is based on the bubble helmets seen in Italy.

This research is being performed using the memex. The memex was first conceived in 1945 in a paper called As We May Think. Since 1945 generations of engineers and scientists have worked tirelessly to make the memex a reality and you know it as the Internet. Its original purpose was to Educate and perform Research. E-commerce and social media came much later and many that used the Internet for Research and Education have died. The memex is being used by healthcare providers around the world to deal with the COVID-19 disaster in real time. Please forward the information  on this page to everyone everywhere.
