Simple, Inexpensive Mechanical Ventilator by University of Minnesota

A team at the University of Minnesota has designed a mechanical ventilator that is inexpensive and made of easy to obtain materials. Unlike traditional ventilators, the Coventor does not require pressurized oxygen. The device consists of a frame and mechanical actuator that compresses a traditional ambulatory ventilation bag (aka Ambu bag or bag valve mask), which is connected to the patient’s endotracheal tube and is used to pump either external compressed oxygen or ambient air.
