#$%^&*AU2015202424A120150528.pdf#####ABSTRACT Described here are devices for intranasally delivering therapeutic gases to a patient. The devices may include a measurement chamber, a combination of 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. 14WO 2011/1153261 117 PCTIJMS2OI 11038791 C~C 00 L) SLO g)l 10 Co~ ~ ~ Fg I_________
