System for Providing Blood Glucose Measurements to an Infusion Device

Abstract

An infusion system includes a characteristic determining device and an infusion device. The characteristic determining device includes a receptacle for receiving and testing an analyte from the user to determine a concentration of the analyte in the user. The characteristic determining device also includes a communication system for transmitting a communication including data indicative of the determined concentration of the analyte in the user, and the infusion device includes a communication system for receiving the communication from the characteristic determining device. The infusion device further includes a bolus estimator for calculating an estimated amount of fluid to be infused into the body of the user based upon the received data indicative of the determined concentration of the analyte in the user and a target concentration of the analyte in the user, and an indicator to indicate when the estimated amount of fluid to be infused has been calculated.

Description

RELATED APPLICATIONS[0001]This application claims priority from U.S. Provisional Applications No. 60 / 398,199 filed Jul. 24, 2002 and No. 60 / 412,998 filed Sep. 23, 2002, which are herein incorporated by reference.FIELD OF THE INVENTION[0002]This invention relates generally to infusion systems that are used for infusing a fluid into a user, and in particular, to apparatuses and methods for providing blood glucose measurements to an infusion device.BACKGROUND OF THE INVENTION[0003]Patients with Type 1 diabetes and some patients with Type 2 diabetes use insulin to control their blood glucose (BG) level. Typically, if a patient's BG level is too high, the patient can inject a “bolus” (dose) of insulin to lower his / her BG level from its present level to a desired target level. Furthermore, patients may inject a bolus of insulin in anticipation of ingesting carbohydrates, thus heading off a sharp rise in their BG level. Patients employ various calculations to determine the amount of insuli...
