First Claim
Patent Images
1. An ambulatory infusion pump comprising:
- an infusion therapy delivery mechanism;
a graphical user interface (GUI) configured to receive a plurality of parameters defining a step delivery function, the plurality of parameters comprising an initial rate, a plateau rate, a step duration, a rate increment and a total infusion volume; and
a processor coupled to the therapy delivery mechanism and configured to calculate an initial infusion duration based on at least one of the plurality of parameters and to cause the therapy delivery mechanism to operate based on the step delivery function.

Abstract
Embodiments relate to systems, methods and devices for delivering a drug or other therapy to a patient with an ambulatory infusion pump configured to provide a series of tolerance-building steps leading up to a plateau delivery rate. The plateau delivery rate is maintained until the prescribed amount of drug or therapy fluid is delivered to the patient. Embodiments of the invention include providing the patient or other user with a mechanism to decrease, or step down, the therapy delivery rate if a tolerance was not achieved at a lower rate, and providing notifications prior to a step up in a dosage delivery rate.
