Early Innovations in Oxygen Concentrator Valves

Humphrey valves were on board in the first in-home oxygen concentrators to hit the market in the early 1980s.

The biomedical manufacturer that holds the first design patent for this technology approached the Humphrey team based on our experience with the diaphragm valves used in the first artificial heart. This partnership resulted in a successful custom diaphragm valve for oxygen concentrators, capable of delivering high flow, precise control, and reliability.

Since then, we have been the leading supplier of valve solutions for portable, transportable, and stationary oxygen concentrators. Our custom-engineered solutions can integrate with each new innovation and evolution in the market.
