| n. ROTH-DRAEGER um 1915 |
The small mask by ROTH-DRAEGER represents the link between the "good old masks" and the highly complicated equipment of our day: the connecting piece connected them with gas bottles that were no longer held in the hand ...
In 1902/03 the physician Dr. Otto ROTH (1863-1944) and the engineer Berhard DRAEGER (died 1928) developed a metal mask with platelet valve as part of a complex anesthesia machine.

In 1948, the Draeger plants in Lübeck - following previous type A to E appliances - produced a model F, a combination of oxygen (10 liter bottle) and nitrous oxide (10 liter bottle) with a 2-liter bottle of carbon dioxide.
The successor models received names from Roman antiquity: Romulus (1952), Cato, Cicero, Sulla ... and populate our operating rooms!
About laughing gas
In 1772, the Anglican clergyman and recreational researcher Joseph PRIESTLEY discovered nitrogen oxide, a gas that Davy experimented with at the beginning of the 19th century. He was able to prove the soporific and euphoric properties of this gas. Because of the uplifting properties of the gas quickly got the nickname "nitrous oxide" and nam the way to the fairs of the world. For forty years, the gas was nothing but an amusement device, taking the fairground guests' control of their language and retenue.
On December 10, 1844, the dentist Horacius WELLS in the small American town of Hartford near Boston experienced how a juggling troupe handled nitrous oxide. He was the first to notice that a fair guest violently nudged his tibia under the influence of laughing gas without a pain reaction! The antalgesic effect of the laughing gas was discovered. Already the next day WELLS pulled himself a wisdom tooth - after inhalation of laughing gas: 11.12.1844, a memorable date!
