CorVent

We designed a simple, inexpensive, and mass-producible ventilator completely from off-the-shelf materials. The device can be made without using any 3D printer, milling machine, lathe machine, servo-motor programmer, or PC. The final price is less than $60. The device has two main features the rate can be tuned easily by rotating a knob and the volume effortlessly can be adjusted by shifting the joint screw.
