Anaesthetic inhaler, 1908. This is an Ombredanne inhaler, invented by Professor Louis Ombredanne (1871-1956) a French surgeon. It was subsequently widely used throughout Europe. In 1907, after two fatalities caused by anaesthesia, Ombredanne designed an inhaler that would be safer to use. It consisted of a metal spherical vessel packed with felt to act as an absorbent wick for liquid ether. The mask fitted over the nose and mouth. The swivel control varied the ratio of ether vapour and re-breathed air.
