For the nitrox semi-closed-circuit rebreather industrial breathing set with liquid gas storage, see Blackett's Aerophor.
An aerophor (sometimes spelled aerophore, aerophon, or aerophone) is a device designed to provide an auxiliary breath supply to aid players of wind instruments in performing extended notes or passages.[1][2] It was invented in 1912 by Bernard Samuels, a Dutch flautist in the Court Theatre of the Grand Duke of Mecklenburg-Schwerin.[3][4][5]
