Adaptive controlled pump control, in particular for adaptive patient-controlled analgesia (APCA)

摘要

The invention relates to an adaptive controlled pump control, in particular for adaptive patient-controlled analgesia (APCA). Adaptive patient-controlled controls are required in medicine for administration of highly active medicaments. Administration of a medicament is worthwhile only to the extent that it is required. This adjustment can only be done optimally by the patient himself/herself. Preliminary technical implementations are to be found in patient-controlled analgesia (PCA) which permits minimum involvement of the patient. In this case, rigid specifications such as inertia periods and constant bolus sizes make adaptation to the constantly changing needs possible to only a limited extent. A significant improvement is brought about by the adaptive patient-controlled pump control, in particular for adaptive patient-controlled analgesia (APCA). The APCA control operates in an open-control loop utilising a biological two-compartment model by means of variable boli and without inertia periods. It permits the patient to adapt the administration of analgesics continuously to his/her need without overdosing the drug. For easy handling, a fully graphic operator unit with parameter-minimised input dialog and display of the course of therapy is used.
