Abstract
The infusion system is provided with a control device (10) wherein a plurality of influence factors with different physiological action mechanisms, i.e. a plurality of semantic domains, is considered as fuzzy information in the automatic dosing of drugs and the semantic significance of the individual domains is taken into account. The control device (10) for controlling at least one infusion apparatus (21) comprises a plurality of fuzzy control units (17,19) structured in a hierarchical system. On a first hierarchical levels, all linguistic variables, measurement values and derived values are examined by a semantic analyzer (16) with regard to the significance of their contents for the various semantic domains. In a unit (18) for evaluation of semantic domains, the results of the above examination are passed through a plurality of evaluation stages to draw conclusions on the operation on a second hierarchical level on which each semantic domain is represented by a fuzzy control unit (19) of its own. By the continuous semantic analysis on the first hierarchical level and the selective controlling of the fuzzy control units (19) on the second hierarchical level, the qualitatively different components of influence as well as the changes in the patient's condition occurring during the treatment, are reliably interpreted in their complex interaction and corresponding to their semantic significance and are included in the automatic dosing of drugs.
