Abstract

The invention relates to a system for delivering anesthesia drugs to a patient. The system comprises means for feeding anesthesia drugs to the patient treated, a measuring device for measuring at least one parameter relating to the effects of the anesthetic drugs fed to the patient, a patient monitor to show the results measured by the measuring devices, and feeding means for feeding patient demographics to the system. The system further comprises means for visual planning of the anesthesia drug delivery before the drugs are actually fed. The system can also comprise means for anesthesia management for drug interaction during the treatment.

Claims

1. System for delivering anesthesia drugs to a patient, the system comprising means for feeding anesthesia drugs to the patient treated, a measuring device for measuring at least one parameter relating to the effects of the anesthetic drugs fed to the patient, a patient monitor to show the results measured by the measuring devices, and feeding means for feeding patient demographics to the system, characterized in that the system comprises means for visual planning of the anesthesia drug delivery before the drugs are actually fed.

2. The system of claim 1, characterized in that the system further comprises means for anesthesia management for drug interaction during the treatment.

3. The system of claim 1, characterized in that the means for visual planning of the anesthesia drug delivery and the means for anesthesia management are combined to a same display unit.

4. The system of claim 1, characterized in that the means for feeding anesthesia drugs comprise either means for inhalational gas anesthetics or intravenous anesthetics.

5. The system of claim 1, characterized in that the means for feeding anesthesia drugs comprise both means for inhalational gas anesthetics and intravenous anesthetics.

6. The system of claim 1, characterized in that the means for visual planning of the anesthesia drug delivery shows different phases of the drug feeding action.

7. The system of claim 6, characterized in that the different phases are timed by the care personnel.

8. The system of claim 6, characterized in that the phases are visualized on the basis of drug modelling for intravenous anesthetics, and MAC, ET or FI for gas anesthetics.

9. The system of claim 3, characterized in that the parameters measured from the patient are shown in the same display unit.

10. The system of claim 9, characterized in that the parameters are at least hypnosis measure.

11. The system of claim 6, characterized in that the phases are based on the actual physiological parameter information.

12. The system of claim 1, characterized in that the visual planning of the anesthesia drug delivery is based on templates formed from the basis of the knowledge of clinic experts and following clinics practices to use drugs and their interactions in different case types.

13. The system of claim 2, characterized in that the means for anesthesia management is connected to a control algorithm that links the parameter values to the drug delivery changes.

14. The system of claim 1, characterized in that the phase timing information is carried out by the care personnel by the acceptance of the next phase.

15. The system of claim 3, characterized in that the display shows advisories and/or alarms based on the measurements from the patient or other clinical practices or settled limits.
