Hi, I published my design last night. I'm keen to see people's thoughts: Click here to see design details
Why :
NHS Rapidly manufactured ventilator system specification: https://www.gov.uk/government/publications/coronav...
The USP of this design is how easy and fast it can scale for mass production for the following reasons:
- Automated production: The production of each part is fully automated (laser cutting), with only 8 different parts
- Only 6 off-the-shelf components: Very few different components are needed and no exotic parts are needed (not even a motor coupling)
- Simple mechanism: It uses a super simple mechanism with just an arm mounted to a motor - no complicated mechanisms to go wrong, just one moving part
- Fast assembly: Complete assembly is possible in around 20 min with one person
- Adjustable settings: Has full adjustment of breath frequency and pressure/tidal volume and with a small adaption can function within all NHS requirements
- Low cost
