DUAL Mechanical Ventilator - laser cut
10mm Plexiglas - UNIT
4mm Plexiglas - Base
All parts are offset from the other parts with 4mm and from the sheet edge with minimum 3mm.
I try to nest all parts on 500 X 500 mm plastic sheet, however some are not fitting in one sheet...
Pads should be made of 10mm ; however I add them to the 4mm sheet also.
Can be used by two patients at the same time!
Are included all .dfx files for laser cutting.
Mechanical parts - Size and Data - all included
It use two Nema 23 steeper motor.
Movement of the ARMS need to be controlled by a pressure sensor what control the air pressured supplied to the patient. Frequency is going to be set by by the medical staff manually.
For the pressure sensor, see adapters design:https://www.thingiverse.com/thing:4274295

ARM PADS position can be adjusted in order to achieve the desire volume of air on each bag; in this way machine can sustain simultaneous two patients! Unfortunately, at the same rates... anyway... better something... than nothing!
Example : No extra nuts/spacers - low volume; two nuts/two spacers - medium volume; four nuts/spacers - full volume.
Tests need to be made in order to find the exact distance between PADS and ARMS pad!
