Motivation
The vital lack of ventilators urged many players to propose alternative solutions to the current defecting line of standard medical devices. Rather massive and proprietary designs were proposed for example by Tesla, other light and open designs were shared to the community like for example OxyGen. Nonetheless, they still require some equipment (like a CNC or a 3D printer) or some parts that are not readily available everywhere.
Investigation
LowTechVent investigates original designs with out-of-the-shelf parts (and a few soldering in some cases) to build a ventilator that could be controlled and pressure-monitored by a mobile phone. Control could alternatively be performed by any computer with a sound card. External monitoring could also be done with an extra sensor. The overpressure can be built with a regular turbine or a loudspeaker, both driven with a relay via the electronics of an amplified speaker possibly bluetooth.
How we built it
Pressure generator: Mobile+bluetooth speaker+relay+turbine+turbine+tubing Pressure monitor: Mobile+tubing or computer instead of mobile + extra pressure sensor for monitoring
What's next for LowTechVent
Envisioned designs should be prospected to offer various options to anybody with respect to the local availabilities in terms of parts and hardware.
