Anaesthesia mask, circa 1910. This is a Yankauer wire frame mask. Sidney Yankauer, a US doctor, introduced the wire-mesh anesthesia mask around 1904. The mask was placed over the patient's nose and mouth and a gauze placed over the mesh. Liquid anaesthetic, such as ether or chloroform, was applied in drops or lightly poured onto the gauze so that the patient breathed in anaesthetic vapour as well as air.
