MECHANIC VENTILATOR - MINI - WAR FIELD - COVID 19

MECHANIC VENTILATOR - MINI - WAR ZONE Those are extreme solutions! Use your own judgment! If you print this project, and you're happy with the final part, don't forget to buy me a roll of filament, or at least a few meters - so I can continue testing and improving these projects or designing new ones! If you're not satisfied with this design or have trouble with your printed parts, send me a message; we'll try to fix it together! If you don't want to or can't afford to buy me a roll of filament... that's okay, I still hope you enjoy printing my designs! To control this unit: For Arduino, see: https://forum.arduino.cc/index.php?topic=675670.0 And also an excellent project completed with control for breathing (insp/expiration): https://www.youtube.com/watch?v=9oZHSspmdJg UPDATE: A new cover that accommodates a bearing (needle bush HK2512 NTN) to ease the rotation of the ventilator. An upgraded version of MECHANIC VENTILATOR - MINI, with thicker walls, a stronger motor (Nema 23), and a motor cover that also serves as a connection for an upgrade - battery and electronics box! See: https://www.thingiverse.com/thing:4245897 As the previous model, a textile loop, controlled by an Arduino, compresses a manual emergency ventilator, acting as a mechanical emergency ventilator. The movement of the shaft, corresponding to the force applied to the bag, must be controlled by a pressure sensor that controls the air pressure supplied to the patient. Frequency will be set by medical staff manually. For the pressure sensor, see adapters design: https://www.thingiverse.com/thing:4274295 and https://www.thingiverse.com/thing:4276846 To prevent damage to the Emergency Bag, a protective SHIELD is used; pass the textile strap through the shield. The length of one coil (for the first one; then it will increase) is slightly over 69 mm. The strap length used for the MINI model was approximately 600 mm. I used a strap removed from an old bag. This system does not have a limit-switch. All parts can be 3D printed. All parts are designed to print without support. All STL files are in the correct position to be printed. It uses a Nema 23 Stepper Motor. This machine has not been tested and is not medical approved. Use it as an extreme solution! Be Safe! Stay Safe!
