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. A system for delivering anesthesia drugs to a patient, the system comprising:

means for delivering gas and intravenous anesthetics to the patient;

a measuring device for measuring at least one parameter relating to the effects of the anesthetics on the patient;

a patient monitor to show the results measured by the measuring device;

feeding means for feeding patient demographics to the system; and

means for visual planning of the anesthetics delivery comprising a user interface for displaying different phases of the anesthetics delivery action before the anesthetics are actually delivered to the patient.

2. The system of claim 1, further comprising means for managing interaction of the anesthetics during treatment of the patient.

3. The system of claim 2, wherein the means for visual planning of the anesthetics delivery and the means for managing interaction are displayed on a single display unit.

4. The system of claim 1, wherein the means for delivering gas and intravenous anesthetics delivers both gas and intravenous anesthetics to the patient.

5. The system of claim 1 wherein the phases are visualized on the basis of drug modeling for intravenous anesthetics, and minimum alveolar concentration (MAC), end tidal agent (ET), or fraction inspired agent (Fl) for gas anesthetics.

6. The system of claim 1, wherein the phases are based on actual physiological parameter information.

7. The system of claim 1, wherein the means for visual planning of the anesthetics delivery retrieves templates from an information management system, and wherein each template is based on one or more of the knowledge of clinic experts, clinical practices, and the use of anesthetic and their interactions in different case types.

8. The system of claim 1, wherein timing of the phases is carried out by acceptance of the next phase.

9. The system of claim 2, wherein the means for managing interaction of the anesthetics is connected to a control algorithm that links the parameters to changes in the anesthetics delivery.

10. The system of claim 3, wherein the parameters measured from the patient are shown on the single display unit.

11. The system of claim 10, wherein the parameters are at least hypnosis measure.

12. The system of claim 3, wherein the single display unit shows advisories and/or alarms based on one or more of the parameters from the patient, clinical practices, and settled limits.

13. A system for delivering anesthesia drugs to a patient comprising:

at least one of an anesthesia machine and an infusion system for delivering anesthetics to the patient;

a measuring device for measuring at least one parameter relating to the effects of the anesthetics on the patient;

a patient monitor to show the results measured by the measuring device;

an information management system for feeding information including patient demographics to the system; and

an anesthesia planning component for visual planning of the anesthetics delivery before the anesthetics are actually delivered to the patient, the anesthesia planning component comprising a user interface for displaying different phases of the anesthetics delivery action before the delivery of the anesthetics drugs to the patient.
