METHOD AND APPARATUS FOR MULTI-INPUT STEPWISE INFUSION PRESCRIPTION
First Claim
1. A drug infusion system for delivering a drug to a patient, comprising:
- a drug delivery module configured to deliver said drug to said patient at one of a series of dosages in each of a series of sequential time slots over a period of time;
a sensor which senses a patient physiological parameter; and
a controller in communication with the sensor and operatively coupled to said drug delivery module to control delivery rates at which said drug is delivered to said patient;
wherein said controller is configured to cause the drug delivery module to deliver said drug in the series of sequential time slots in a manner defined by a formula in which a quantitative drug delivery parameter for each time slot is a function of a seed value, the sensed patent parameter and at least one of;
a) a medical professional-provided profile,b) a patient-chosen parameter, andc) a non-variable parameter.

Abstract
A drug infusion system includes a drug delivery module which delivers a drug in each of a series of sequential time slots over a period of time. The drug delivery module is controlled by a controller which is configured to cause the drug delivery module to deliver said drug in the series of sequential time slots in a manner defined by a formula in which a quantitative characteristic of drug delivery in each time slot is a function of a past drug delivery profile and at least one of: a) a medical professional-provided profile, b) a patient-chosen parameter, and c) a non-variable parameter. The formula may be a function of a medical professional-provided profile and a non-variable parameter may be a parameter chosen by a medical professional. The past drug delivery profile may include a drug delivery parameter in a previous time slot. The patient-chosen parameter may include an input from the patient characterizing the patient'"'"'s condition.

21. A method of delivering a drug to a patient by a drug infusion system comprising:
-
sensing a patient physiological parameter with a sensor; delivering said drug to said patient with an implanted drug delivery module at one of a series of dosages in each of a series of sequential time slots over a period of time; and controlling delivery rates at which said drug is delivered to said patient with a controller that is in communication with the sensor and operatively coupled to said drug delivery module to cause the drug delivery module to deliver the drug in a-manner defined by a formula in which a quantitative characteristic of drug delivery is a function of the sensed patient physiological parameter and a seed value and at least one of; a) a medical professional-provided profile, b) a patient-chosen parameter, and c) a non-variable parameter. - View Dependent Claims (22, 23, 24, 25, 26, 27)
