Abstract

An anaesthetic vaporizer comprises a reservoir (1) for containing liquid anaesthetic agent, pressurizing means (5) for pressurizing the liquid anaesthetic agent in the reservoir, a vaporizing device (12) and a conduit for a carrier gas supply, the vaporizer being arranged such that in use liquid anaesthetic agent contained in the reservoir is pressurized by the pressurizing means and conveyed in liquid form by that pressurization to the vaporizing device where it is vaporized for delivery to a patient with the carrier gas, wherein both the pressurization and the conveyance of the liquid anaesthetic agent to the vaporizing device are controlled independently of the carrier gas supply.
