A design package for an emergency, rapid-deployment ventilator system.


  • Mechanical ventilation or assisted ventilation


Researchers at the University of Minnesota have designed Coventor - a simple, low-cost mechanical ventilator system that can potentially be used to solve ventilator shortages in hospitals and make-shift clinics. Coventor is a device that repurposes the Bag Valve Mask manual resuscitator (“Ambu bags”), which are commonly used by paramedics and emergency medicine specialists in ICUs and ambulances. This mechanical ventilator consists of a mechanism that can continuously compress and release a reservoir bag, and a control system to adjust the respiratory rate and limit the pressure of air pushed into patients.

Designed by an anesthesiologist and engineers, this design represents a realistic approach to rapidly build life-sustaining mechanical ventilation to patients in need. The design specifications package of this is now available for download at no cost.

Key Benefits & Differentiators

  • Simple parts and manufacturing process; the frame can be metal-stamped or injection molded
  • Although most patients will require oxygen, the device itself does not require pressurized oxygen or air supply to function; uses available manual resuscitator bags
  • Compact tabletop (or desktop) size; ideal for make-shift clinics
  • Easy to use for ICU-trained medical professionals
  • Low cost and scalable design
