Claim:
1. A data processing device for an anesthesia device, which has a feed for three anesthetics including two hypnotics, one of which is an intravenously administered hypnotic and the other a volatile hypnotic, and an opioid, and includes a feed control for adjusting a volume flow, the data processing device comprising: a data input receiving data of the anesthetic volume flows being fed; a pharmacokinetic model calculations module to determine and standardize respective effective plasma or site of action concentrations of the anesthetics being administered from continuously fed data of the volume flows of the anesthetics being administered, wherein the determined effective plasma or site of action concentration of each anesthetic is divided for standardization by an effect concentration of the anesthetic, determined in advance, at which a preset percentage of patients shows a certain effect, and the standardized concentrations of the hypnotics are added up to a total hypnotic concentration and provided as pharmacokinetic model calculations module output values; an isobole model calculation module receiving data, related to currently determined standardized concentrations, from the pharmacokinetic model calculations module and calculating, and providing as isobole model calculation module output values, at least one isobole as an isobole curve in a coordinate plane, which is defined by a total hypnotic concentration axis and an opioid concentration axis, as a function of the currently determined standardized concentrations; and a display module connected to a display device, the display module receiving pharmacokinetic model calculations module output values and isobole model calculation module output values and forming a two-dimensional action diagram, in which the y-axis is an indicator of the total hypnotic concentration and the x-axis is an indicator of the standardized opioid concentration and in which at least the data of the currently calculated standardized total hypnotic concentration and opioid concentration values are displayed and the at least one calculated isobole curve is displayed, wherein the display is adapted to changes occurring in the at least one calculated isobole curve in the course of time with the standardized total hypnotic concentration and opioid concentration changing in the course of time.
