A ventilator made from off the shelf industrial automation parts, recreating simple all-pneumatic (no electric power required) ventilators that have been in service continuously since the late 70's. This ventilator can be built from a kit with no special tools, and is easy to assemble. It is not subject to the current supply chain shortages of existing ventilators and their component parts.
MakerVent has passed ISO 18562 testing ! Final report and risk analysis will be back in a couple of weeks, but in a conference call with the testing lab, they have informed us that VOC analysis shows a very small number of compounds present, and all well within safe margins. We had already been informed that the particulate test had passed. So this ventilator will safely deliver breathable gas. This ventilator is one of the first, if not the first (it may be) to use off the shelf industrial automation, non-medical, components, and pass these safety of breathable gas tests - showing that with careful choice of materials, and expert cleaning (check out our team page, http://MakerVent.com/team to learn more about the cleaning lab), ventilators can be built like this and safely deliver breathable gas. An important milestone !!!
Particulate test complete and results reviewed, the ventilator passed !
VOC (volatile organic compounds) tests completed, samples still awaiting detailed analysis, at testing lab.
Getting professional regulatory and quality management assistance for the request to the FDA for authorization for use in the Covid-19 pandemic. Steady progress on documentation and creation of audit-able assembly and test procedures. We have built two here in Arizona so far.
The machine is solid, and in fact one of our team members in London UK has built his own version of the ventilator, in a different enclosure, but the same basic design and components, which he is using to characterize pressure and volume profiles, and other facets of ventilator operation.
