What is the history of the nebulizer?
In 1858, Sales-Girons invented the first inhaler that atomized liquid medication using pressure. Closely following this invention was the steam-driven nebulizer in Germany in the early 1860s. The Pneumostat was invented in the 1930s and was the first electrical nebulizer, according to Inhalation Therapy: A Historical Review. It used a medical liquid to relax bronchial muscles by using an electrical compressor to convert the liquid into an aerosol. A hand-driven alternative known as the Parke-Davis Glaseptic was also in use at the same time.
