INFUSION SYSTEM PROGRAMMABLE IN FLEX MODE
First Claim
1. A drug infusion system capable of delivering a fluid medication to a patient under direction of a medical professional, comprising:
- a drug delivery module capable of delivering said fluid medication to said patient continually at a basal rate and capable of delivering said fluid medication at an interval rate in each of a plurality of time slots over a specified period of time, said interval rate being different from said basal rate;
controller, programmable by said medical professional, operatively coupled to said drug delivery module to control said basal rate and said interval rate at which said fluid medication is delivered to said patient;
wherein said controller, upon being pre-programmed by said medical professional to deliver an interval rate for at least one of said plurality of time slots, calculates a total dose of said fluid medication to be delivered to said patient over said period of time based on said basal rate and said interval rate for each of said plurality of time slots, compares said total dose against a maximum dose and calculates an adjusted basal rate, if necessary, so that said total dose does not exceed said maximum dose; and
a display, operatively coupled to said controller, configured to communicate said adjusted basal rate to said medical professional.

Abstract
A drug infusion system capable of delivering a fluid medication to a patient under direction of a medical professional continually at a basal rate and at an interval rate in each of a plurality of time slots over a specified period of time. The total dose of the fluid medication to be delivered to the patient over the period of time based on the basal rate and the interval rate for each of the plurality of time slots is determined, compared the total dose against a maximum dose. The basal rate is adjusted, if necessary, so that the total dose does not exceed the maximum dose.

16. A method of delivering a fluid medication from an implanted device to a patient under direction of a medical professional, said implanted device being part of a system, comprising the steps of:
-
manually programming said implanted device with a preferred dose, a basal rate and a plurality of interval rates over a specified period of time, each individual one of said interval rates corresponding to an individual one of a plurality of time slots during said specified period of time; said system calculating a total dose over said specified period of time based on said basal rate and said interval rates, each individual one of said interval rates corresponding to an individual one of said plurality of time slots; said system calculating an adjusted basal rate so that said total dose does not exceed said preferred dose; and communicating said adjusted basal rate to said medical professional. - View Dependent Claims (17, 18, 19)

20. A method of delivering a fluid medication from an implanted device to a patient under direction of a medical professional, said implantable medical device being part of a system, comprising the steps of:
-
manually programming said implanted device with a basal rate and a plurality of interval rates over a specified period of time, each individual one of said interval rates corresponding to an individual one of a plurality of time slots during said specified period of time; said system calculating a total dose over said specified period of time based on said basal rate and said interval rates; manually adjusting at least one of said plurality of interval rates; said system calculating an adjusted basal rate in accordance with said plurality of interval rates as adjusted in said manually adjusting step; and communicating said adjusted basal rate to said medical professional.
