AN APPARATUS FOR SUPPLYING A PATIENT A MIXTURE OF A CARRIER GAS AND A GASEOUS ANAESTHETIC AGENT

摘要

An apparatus (1) for supplying a patient with a mixture of a carrier gas and a gaseous anaesthetic agent, said apparatus comprising a producing part (2,) for providing the gaseous anaesthetic agent by evaporating a volatile liquid anaesthetic agent, and an operating part (3) for operating the producing part (2). The producing part comprises a liquid container (5), a gas container (6) and a pump (8) for dosing the liquid anaesthetic agent to the gas container (6) inserted in a connection (7) between the two containers. Said components of the producing part are permanently connected to each other during the lifetime of the producing part. This is an advantage e.g. when the producing part (2) is a disposable enclosure (4), since this will ensure that the producing part easily can be replaced with a new producing part restoring the anaesthetic supply in the apparatus quickly and easily without the operator having to spend time on cleaning and sanitising/sterilising the components of the producing part.
