Abstract

An audible pressure relief valve for a medical humidifier used in inhalation therapy. This valve relieves pressure from the humidifier when there is a kink or obstruction in a humidified oxygen tube leading to a patient's mask, nasal cannula or tent. The valve has a rubber disc that is dimensionally tuned to vibrate against a valve seat and emit an audible sound over a wide range of oxygen flow rates. This valve audibly vibrates at gas flow rates of 3 to 15 liters per minute and pressures of 1 to 5 psi above atmospheric pressure.
