Infusion pump system and methods

摘要

Some embodiments an infusion pump system can be configured to modify alarm limit parameters as the user's insulin load increases or decreases. Moreover, in particular embodiments, the infusion pump system can be configured to provide a “missed bolus” or “missed meal” alarm in response to the user's blood glucose characteristics, the user's insulin load information, or the like.

主权项

1. A medical infusion pump system, comprising:
a portable pump housing that receives insulin for dispensation to a user, the pump housing at least partially containing a pump drive system to dispense the insulin through a flow path to the user; and a controller that communicates with the pump drive system to dispense the insulin from the portable pump housing, the controller being configured to calculate an insulin load of the user representing an estimated amount of insulin delivered to the user's body which has not yet acted, wherein the controller receives glucose information indicative of a detected blood glucose level of the user, and wherein the controller outputs an alarm when the glucose information indicates that the detected blood glucose level reaches beyond a glucose alarm limit parameter, the glucose alarm limit parameter being adjustable by the controller in response to the insulin load of the user representing the estimated amount of insulin delivered to the user's body which has not yet acted.
