Abstract

A 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. The system further comprises means for anesthesia management for drug effect during the treatment, the means for anesthesia management. The means for anesthesia management is connected to a control algorithm that links the parameter values to the drug delivery changes.

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, the system further comprising means for anesthesia management for drug effect during the treatment, the means for anesthesia management being connected to a control algorithm that links the parameter values to the drug delivery changes.

2. The system of claim 1, wherein the means for anesthesia management comprises a user interface having control means for selecting appropriate preconfigured control algorithm that leads to a desired result.

3. The system of claim 2, wherein the control means is a switch arrangement comprising means for keeping the patient with the same measured anesthesia level or drug concentration.

4. The system of claim 3, wherein the switch arrangement further comprises means for slightly increasing, in pre-determined manner, the anesthesia level or drug concentration.

5. The system of claim 3, wherein the switch arrangement further comprises means for slightly decreasing, in pre-determined manner, the anesthesia level or drug concentration.

6. The system of claim 3, wherein the switch arrangement comprises means for automatically selecting the procedure, which leads to quick increase, in predetermined manner, in hypnotic drug concentration.

7. The system of claim 3, wherein the user interface comprises a predictive graphical display for showing the predicted effects of the procedure selected by the switch arrangement.

8. The system of any of claim 1, wherein the means for anesthesia management comprises a library of preconfigured templates for selecting the correct rate of changes.

9. The system of claim 8, wherein the templates are shown in the graphical display.

10. The system of claim 1, wherein that the means for feeding anesthesia drugs comprise means for inhalational gas anesthetics and/or intravenous anesthetics.

11. The system of claim 2, wherein the user interface shows different phases of the drug feeding action.

12. The system of claim 11 wherein the different phase are timed by care personnel.

13. The system of claim 7, wherein the predictive graphical display shows also parameters measured from the patient.

14. The system of claim 2, wherein the interface is visualized on the basis of modelled drug effects PK and/or PD for intravenous anesthetics and MAC or ET or FI for gas anesthetics.

15. The system of claim 6, wherein rate of volatile hypnotic drugs given to the patient is increased by increasing anesthetic concentration in the gas and by increasing the flow of gas.

16. The system of claim 1, wherein the drug effect comprises drug interaction.
