Abstract
Devices for intranasally delivering therapeutic gases to a patient. The devices may include a measurement chamber, a combination pressure regulators and a sequencing mechanism that controls valves associated with the pressure regulators. When implemented in a hand-held dispenser, the hand-held dispenser may reliably deliver consistent doses of gas regardless of the unknown state and pressure of the therapeutic gas in the measurement chamber.
