Anesthetic metering system
First Claim
1. An anesthetic metering system comprising:
- an anesthesia apparatus with a mounting element and a metering line;
an anesthetic reservoir with a liquid anesthetic reserve limited by a flexible material wall;
a propellant applying pressure acting on the liquid anesthetic reserve via the flexible material wall material;
a first valve element connected to the anesthetic reservoir and in flow connection with the liquid anesthetic reserve, the first valve element being insertable into an anesthesia apparatus mounting element; and
a volumetric nozzle connected to the metering line for the metered release of anesthetic to the anesthesia apparatus.

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.
