Introduction: Affordable Ventilator
During the current COVID-19 pandemic, hospitals are on the verge of having a shortage of critical lifesaving supplies. Common ventilators are expensive to produce. So here is one way to make an affordable automatic ventilator using easily accessible supplies
- Bag Valve Mask (BVM): I borrowed mine from work, but you could find one at www.medexsupply.com
- Two small springs: Lowe's
- 4 small hooks: Lowe's
- 2 rubber rigid casters: Lowe's
- 3D Printed Parts: Rack and Pinion, wheel track
- 3 jumper wires: Lowe's
- Arduino Uno: Amazon
- Continuous rotation server motor: Walmart
Step 1: Step 1: 3D Print Rack and Pinion, and Wheel Track
Use similar CAD drawings to these, with dimensions that fit with the BVM you have.
Step 2: Step 2: Assemble
Secure wheel track, standing support, and BVM holder to the base.
Make compressing arm cart by attaching 3D printed rack to the compressing arm and the base with wheels.
- Attach the two springs underneath the BVM holder from the standing support to the compressing arm cart using the 4 small hooks.
