"Makers For Life" Project - Coronavirus COVID-19
WHY :
If covid-19 positive patients outnumber artificial ventilation capacity of the hospitals, unconventional artificial respirators could be offered to non-priority or less-severe patients. Beyond limiting the risks of population-wide panic of under-equipment, The Makers For Life project may reduce the conundrum placing the health care system in a situation where limited resources should be allocated to patients in need.
The plan aims at increasing by a few dozen to hundred units by the end of the week respiratory assistance devices thus diminishing the allocation constraints of more sophisticated materials.

WHAT :
The project is not a mechanization of AMBU-Bag/BAVU but a real mechanical ventilation for invasive use (probe) ensuring PEEP in accordance with the recommendations for COVID-19 management.

HOW :
As hospitals will soon lack mechanical artificial respirators, the project aims at building a pump, and a valve system (controlled by electronics). This way, the breathing cycle can be enforced by proper air routing through the valve system.
The overall system is composed of sub-components that can be plugged together and wired to form an air circuit, namely:
- Air pump (called "Blower");
- Valve system (routing variant) (called "Air Transistor" — will be used in V2);
- Valve system (depressuring variant) (called "Pressure Valve" — used in V1);
- Valve system (two-way variant) (PEEP valve, called "Two-Way Valve");
- Venturi valve (called "Oxygen Mixer");
- Air filter casing (called "Filter Box");
- Pipe adapters (called "Adapters");
In order to ensure a proper breathing cycle (inhale + exhale), multiple valves need to be connected together to form a circuit. The motors needs to be controlled in harmony so that the air routing between each valve unit is consistent.
