An anesthetic evaporator unit () with an anesthetic container () for receiving liquid anesthetic, with a gas line () with an open-pore, porous line wall () for guiding gas and for enriching the gas with anesthetic, and with an anesthetic-guiding wick (), which extends from an interior space () of the anesthetic container () to the line wall () in order to supply the line wall () with anesthetic from the anesthetic container (). The anesthetic evaporator unit () has a heater () for heating the gas line (). A method for controlling the anesthetic evaporator unit () is also provided.

Anesthetic evaporator unit

A wick () includes a porous molding, which has a plurality of air ducts () extending in the vertical direction, a plurality of upper deflection chambers (), which connect each a first air duct pair () of the plurality of air ducts () to one another, and a plurality of lower deflection chambers (), which connect each a second air duct pair () of the plurality of air ducts () to one another. The two air ducts () of the second air duct pairs () are each associated with different first air duct pairs (). An anesthetic evaporator () includes a housing (), which receives the wick (), so that the vertical air ducts () and the upper and lower deflection chambers () form an air flow duct between the air inlet () and the air outlet ().

Anesthetic evaporator and wick for an anesthetic evaporator

An anesthesia system for providing a breathing gas enriched with anesthetic has an anesthesia apparatus () and at least one anesthetic dispensing device (), which is detachably coupled with the anesthesia apparatus. A fluid connection () is provided between the anesthesia apparatus and the dispensing device, which is designed to send anesthetic from the dispensing device into the anesthesia apparatus. At least one optical interface is provided between the anesthesia apparatus and the dispensing device. At least one display device is provided in the dispensing device. The optical interface has at least one light source (), which is provided in the anesthesia apparatus, and at least one fiber optic light guide (), which is provided in the anesthetic dispensing device (). The light fed by the light source () into the fiber optic light guide is sent to the display device to directly or indirectly light the display device.

Anesthesia system with detachable anesthetic dispensing device

A filling device for an anesthetic dispenser has a closing element () that can be inserted into the filler neck () and can again be removed from same in a simple manner. A bayonet catch is provided between the closing element () and the filler neck () combined with a ring seal (). The a ring seal () can be pressed in an axial direction by axial rotation and has an elastically deformable spring element.

Filling device for an anesthetic dispenser

A dispensing element of an anesthetic vaporizer is provided that can be manufactured in a simple manner and makes it possible to dispense anesthetic over a broad setting range. The dispensing element () includes two, longitudinally extending dispensing channels (), which are connected to one another in terms of flow by means of a connection channel (). The gas flows from one of the dispensing channels () into the other dispensing channel () via the connection channel ().
