This hand-ball nebuliser comes from Seattle. The printed leaflet tells us that Dr Paschall was a pioneer in perfecting a method to inhale epinephrine, and that his goal was achieved in 1933. This pack, though, is from a later period. The Breatheasy nebuliser is made of Pyrex glass and the rubber ball is supplied by the Goodrich Rubber Company. The inhalant was a 3% solution of synthetic epinephrine hydrochloride together with preservative and isotonic buffer.
