Elsberg Ether apparatus
Date of manufacture:
The apparatus is designed for delivering ether vapour by intratracheal insufflation (circa 1910). The main body of the apparatus has an upper ether vessel with a (warm) water reservoir below. Fresh gas enters through a narrow bore nozzle at the left, passing a tap that offers connection to air or to a mercury u-tube blow-off. The gas then passes to a system of 3 cog-linked valves that divide the flow through the liquid ether chamber or via a bypass to the outlet nozzle. A thermometer indicates the ether mixture temperature close to the outlet.
