An arrangement for supplying a medical apparatus with anesthetic is so improved that, when changing the anesthetic supply vessel ( ), the new anesthetic is made available directly and, when there is a malfunction of an anesthetic metering device ( ), an exchange is possible in a simple manner. The arrangement includes a supply vessel ( ) for the liquid anesthetic ( ), a metering device ( ) for liquid anesthetic and a pin-and-socket connection ( ) between the metering component ( ) and a vessel receptacle ( ) of a medical apparatus ( ). The metering component ( ) is electrically drivable and is connected to the supply vessel ( ) so as to form a modular unit.

Arrangement for supplying a medical apparatus with anesthetic

A respirator with an inhalation line (,) connected to a gas supply device (,) and with an exhalation line (,) connected to an exhalation device (,), with a Y piece (,) connecting the inhalation line (,) to the exhalation line (,), and with a patient connection (,) going out from the Y piece (,). Partial rebreathing of CO,-containing exhaled air is made possible in a simple manner by providing a switchover device (,) between the inhalation line (,) and the gas supply device (,) as well as between the exhalation line (,) and the exhalation device (,). The switchover device is designed such that the flow connection is established between the inhalation line (,) and the gas supply device (,) as well as the exhalation line (,) and the exhalation device (,) in a first switching position and there is at least a flow connection between the gas supply device (,) and the exhalation line (,) in the second switching position.
