    • For automatic supply of an active substance to a patient's body (14) the supply rate (R) of an infusion pump (13) is evaluated. The supply rate is processed in a patient model (11) which receives the corresponding active substance data from a drug data bank (12). The patient model (11) calculates the concentration (CNactual) in the patient's body from the former values of the active substance supply. Said actual concentration value is fed to a concentration controller (17) which also receives a desired concentration value (CNdesired). The infusion pump (13) is controlled as a function of the difference obtained. The desired concentration value can be manually set on an input device (19) or is supplied by another control portion which generates e. g. a BIS level or an adequate signal from the patient's EEG, the BIS level being a measure of the depth of anaesthesia.
    • 为了将活性物质自动供应到患者体内(14),评估输液泵(13)的供给速率(R)。 在从药物数据库(12)接收相应的活性物质数据的患者模型(11)中处理供给速率。 患者模型(11)从活性物质供应的前值计算患者体内的浓度(CNactual)。 所述实际浓度值被馈送到浓度控制器(17),其也接收期望的浓度值(CN desired)。 作为所获得的差异的函数控制输液泵(13)。 期望的浓度值可以手动设置在输入设备(19)上,或者由另一个控制部分提供, G。 来自患者脑电图的BIS水平或足够的信号,BIS水平是麻醉深度的量度。
