Abstract

An anaesthetic vaporlser includes a passagevay 10, 30 for directing carrier gas through a fixed laminar restrictor 32 to a vaporising chamber 26. Liquid anaesthetic agent ls injected into the vaporising chamber 26 from a constant level tank 12 the output of vhich is controlled by a laminar control valve 28. Liquid anaesthetic agent flov is determined by the pressure of carrier gas in the passagevay 10, 30 and the setting of the liquid laminar control valve 28.
