ABSTRACT:
An anesthetic metering system includes an anesthetic reservoir (1) having an anesthetic reserve (2), which is limited by a flexible material wall and to which pressure is admitted by means of a propellant (3) acting thereon via the wall material. The anesthetic reservoir (1) has a first valve (4), which is in flow connection with the liquid anesthetic reserve (2) and can be inserted into a mounting element (6) of an anesthesia apparatus. The metered release of anesthetic to the anesthesia apparatus takes place via a volumetric nozzle (8). The present invention provides an anesthetic metering device which avoids, on the one hand, the drawbacks of the anesthetic evaporators used previously, which are to be refilled with anesthetics at the workplace, and makes possible the refilling of the anesthetic reservoir (1) at the anesthetic manufacturer, on the other hand.
