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.
Claims21
1-20. (canceled)
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 is configured to receive a passcode and a plurality of predefined parameters defining a step delivery therapy profile having a first medicament delivery rate, a current step duration, and a new step duration, the control module further configured to, upon entry of the passcode, step up the medicament delivery rate to a second medicament delivery rate for the new step duration independent of progress on the current step duration when the step up command was entered.
An ambulatory infusion pump configured to graphically illustrate progress along a programmed step delivery profile during a therapy session, the ambulatory infusion pump comprising:
- a pump control system configured to control operation of a pumping mechanism according to one or more delivery rates defined by the programmed step delivery profile;
- and
- a control module in communication with the pump control system, the control module including a user interface presenting an indicator graphic along with a step delivery profile graphic configured to illustrate progress along the step delivery profile during the therapy session,
- wherein the user interface is further configured to receive a passcode to permit stepping up the one or more delivery rates for a predefined new step duration independent of progress along the step delivery profile and to change the presentation of the step delivery profile graphic to reflect the step up.
An ambulatory infusion pump configured to deliver medicament according to a customized delivery profile that enables a patient to gradually build up a tolerance to the medicament during a therapy session, the ambulatory infusion pump comprising:
- a pump control system configured to control operation of a pumping mechanism according to one or more tolerance-building delivery rates defined by a step delivery profile;
- and
- a control module in communication with the pump control system, the control module including a user interface presenting an indicator graphic along with a step delivery profile graphic configured to illustrate progress along the step delivery profile during the therapy session,
- wherein the user interface is further configured to receive a passcode to permit stepping up one of the one or more tolerance-building delivery rates for a predefined new step duration independent of progress along the step delivery profile and to change the presentation of the step delivery profile graphic to reflect the step up.
