Abstract:
1. An anesthesia system, comprising: an anesthesia apparatus; an anesthetic dispenser with an anesthetic reservoir; at least one dispensing parameter detection means, said at least one dispensing parameter detection means comprising a filling level detection means for capacitively detecting a quantity of anesthetic present in said anesthetic dispenser, said filling level detection means comprising capacitor surfaces, between which the anesthetic is located, wherein a changing quantity of anesthetic brings about a change in a quantity of dielectricity between the capacitor surfaces, which is an indicator of the quantity of anesthetic; and a contactless interface between the anesthesia apparatus and the anesthetic dispenser for transmitting data, including dispensing parameters and for supplying the at least one dispensing parameter detection means with energy, wherein the data and energy transmission takes place by electromagnetic field forces.
