Sumps for liquid anaesthetic agent for use in anaesthetic vaporisers are provided with features to minimise carry over of liquid anaesthetic agent from the sump into a patient's breathing circuit. A chamber (12) may be provided, located above the sump body (2) through which vapour leaving the body through the outlet conduit(10), and liquid agent associated with the vapour, are passed and in which the liquid agent is deposited, with a liquid return conduit (14) through which liquid anaesthetic agent deposited in the chamber can return to the sump body. A sump may be provided with a device (18) for detecting an increase in the level of liquid in the sump body above a predetermined level, and a valve by which flow of vapour through the outlet conduit from the sump body can be controlled when that predetermined level is exceeded. |
