Technology No. 2021-160
IP Status: PCT Pending; Application number PCT/US2023/073342.


  • Deliver large volumes of oxygen to patients
  • Intravenous gas exchange

Technology Overview

Researchers at the University of Minnesota have developed a novel device for the intravenous delivery of large volumes of oxygen to critically ill patients. Oxygen delivery is increased via the use of a porous polymer material to assist in the diffusion of oxygen under high pressures. Control of the pressure and flow rate facilitate the formation of oxygen nanobubbles and the exchange of carbon dioxide. This technology has the potential to eliminate intubation and change critical care practices as the need for sedation and ICU care would be minimized.
