System and method for adaptive drug delivery
First Claim
1. A system for controlling the administration of medication to a patient to achieve and maintain a target effect in said patient, the system comprising:
- a sensor package having one or more sensors, said sensors being configured to sense an attribute of said patient and to provide a parameter indicating the attribute being sensed;
a medication delivery unit configured to administer said medication to said patient to achieve a concentration of said medication in said patient; and
a medication delivery controller having an input coupled to said sensor package and an output coupled to said medication delivery unit, said medication delivery controller being configured to accept said one or more parameters from said sensor package, to determine a target concentration level of said medication to achieve said target effect, and to control said medication delivery unit to deliver said medication at a rate determined to achieve said target concentration level of said medication in said patient.

Abstract
A system and method for controlling the administration of medication to a patient utilizes adaptive feedback to achieve and maintain a target effect in said patient. A sensor package having one or more sensors is used to sense an attribute of the patient and to provide a parameter indicating the attribute being sensed. A medication delivery controller accepts one or more parameters from the sensor package and uses these parameters to determine the effect of a medication on a patient and the concentration level of medication that will achieve a desired effect. The medication delivery controller controls the medication delivery unit to deliver the medication at a rate determined to achieve said target concentration level of said medication in said patient. If the patient'"'"'s response to a given medication changes as a result of external stimuli, the medication delivery controller can detect this change and determine a new concentration level of medication which will achieve the desired effect. The medication delivery controller can steer the medication delivery unit to administer an amount of medication to reach this new concentration level.

9. A processor-based system for running program code to control the administration of medication to a patient to achieve and maintain a target effect in said patient, the program code comprising:
-
program code for determining whether the patient'"'"'s response to a target concentration level of said medication has changed;
program code for computing a patient response profile reflecting the patient'"'"'s new individualized response to said medication; and
program code for using said second patient response profile to determine a new concentration level of medication to maintain said target effect in said patient. - View Dependent Claims (10, 11, 12, 13)
