Caption

Oxford Vaporizer. Mechanical vaporizers convert liquid anaesthetics into gaseous form, and deliver them at the right concentrations for anesthesia. This device was invented by 1941 by H.G Epstein and R.R. Macintosh. The bellows drew air through the vaporizer where it mixed with the ether vapour. The ether was maintained at a constant temperature and the ratio or air and ether could be varied to control the degree of anaesthesia. Ether has since been superceded by safer anaesthetics.
