First Claim
Patent Images
1. An ambulatory infusion pump for providing step delivery therapy to a patient comprising:
- a pump control system configured to control operation of a pumping mechanism; and
a control module configured to relay commands to the pump control system, wherein the control module can be configured to receive a plurality of predefined parameters defining a step delivery therapy profile having an initial infusion duration, the step delivery therapy profile comprising an initial medicament delivery rate followed by one or more stepped changes in the medicament delivery rate, and the control module can be further configured to selectively override the step delivery therapy profile by one of;
(a) holding the medicament delivery rate constant, or(b) reversing the one or more stepped changes in the medicament delivery rate back to a previous medicament delivery rate,and the selection of (a) or (b) is based at least in part on a patient'"'"'s monitored condition, wherein the control module is configured to automatically calculate a new adjusted infusion duration if the step delivery profile is overridden, and continuing the step delivery therapy for the length of said new adjusted infusion duration.

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.

11. A method of defining a step delivery therapy for an ambulatory infusion pump comprising:
-
receiving a plurality of predefined parameters defining a step delivery therapy profile, the step delivery therapy profile comprising an initial medicament delivery rate followed by one or more stepped changes in a medicament delivery rate; calculating an initial infusion duration delivery time; selectively overriding the step delivery therapy profile by one of (a) holding the medicament delivery rate constant, or (b) reversing the one or more stepped changes in the medicament delivery rate back to a previous medicament delivery rate, with selection of (a) or (b) based at least in part on a patient'"'"'s monitored condition; and automatically calculating a new adjusted infusion duration delivery time, and continuing the step delivery therapy for the length of said new adjusted infusion duration. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. An infusion system for providing step delivery therapy to a patient comprising:
-
at least one ambulatory infusion pump comprising a pump control system configured to control operation of a pumping mechanism and a control module configured to relay commands to the pump control system; at least one external computing system in communication with a control module of the at least one ambulatory infusion pump; wherein the control module is configured to receive from the at least one external computing system a plurality of predefined parameters defining a step delivery therapy profile, the step delivery therapy profile comprising an initial medicament delivery rate followed by one or more stepped changes in the medicament delivery rate over the course of a calculated infusion duration; and wherein the control module is further configured to selectively override the step delivery therapy profile by one of (a) holding the medicament delivery rate constant or (b) reversing the one or more stepped changes in the medicament delivery rate back to a previous medicament delivery rate, with selection of (a) or (b) based in part on the patient'"'"'s condition, wherein the control module is configured to automatically calculate a new adjusted infusion duration if the step delivery profile is overridden, and continuing the step delivery therapy for the length of said new adjusted infusion duration.
