SYSTEM AND METHOD FOR MODIFYING MEDICAMENT DELIVERY PARAMETERS AFTER A SITE CHANGE

摘要

Apparatuses and methods for delivery of medicaments such as insulin disclosed herein can increase the effectiveness of therapy by adjusting medicament delivery parameters to account for the loss of medicament absorption upon delivering medicament at a new insertion site. When a needle is inserted at a new site on a patient's body for delivery of medicament to that patient, a natural inflammatory response by the body to insertion of the needle causes the body to resist absorption of the delivered medicament. However, this medicament resistance decreases over time. Embodiments of the invention therefore adjust medicament delivery to deliver less medicament as time passes after an infusion set change causes medicament to be delivered at a new insertion site.

主权项

1. A portable infusion pump, comprising:
a pump device configured to deliver medicament to a user through an infusion set in fluid communication with the pump device and physically connected to the user's body; and a processor communicatively coupled to the pump device to control the pump device to deliver the medicament to the user, the processor further configured to:
determine that a first infusion set has been detached from fluid communication with the pump device and a second infusion set has subsequently been placed into fluid communication with the pump device;initiate delivery of medicament with the pump device through the second infusion set; andadjust delivery of medicament with the pump device through the second infusion set based on a time since initiating delivery of medicament through the second infusion set.
