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.

95. An infusion system for infusing insulin into a body of a user, the infusion system comprising:
-
a blood glucose test strip meter including; a meter housing adapted to be carried by the user; a test strip port coupled to the meter housing to receive a test strip and test a blood sample from the user to determine a blood glucose level of the user; a meter processor contained in the meter housing and coupled to the test strip port to process the determined blood glucose level from the test strip port; and a wireless meter communication system contained in the meter housing and coupled to the meter processor to transmit a communication including data indicative of the determined blood glucose level of the user; and an infusion device including; an infusion device housing adapted to be carried by the user; a drive mechanism contained in the infusion device housing and operatively coupled with a reservoir containing insulin to infuse insulin into the body of the user; a wireless infusion device communication system contained in the infusion device housing to receive from the wireless meter communication system the communication including the data indicative of the determined blood glucose level of the user; an infusion device processor contained in the infusion device housing and coupled to the wireless infusion device communication system to process the data indicative of the determined blood glucose level of the user and control the infusion device; and a bolus estimator used in conjunction with the infusion device processor to calculate an estimated amount of insulin to be infused into the body of the user based upon the received data indicative of the determined blood glucose level of the user. - View Dependent Claims (96, 97, 98, 99, 100, 101, 102, 103, 104)

105. In an infusion system including a blood glucose test strip meter and an infusion device, a method for infusing insulin into a body of a user, comprising:
-
receiving and testing a blood sample from the user on a test strip to determine a blood glucose level of the user; transmitting wirelessly with the blood glucose test strip meter a communication including data indicative of the blood glucose level of the user; receiving wirelessly with the infusion device the communication including the data indicative of the blood glucose level of the user; and calculating an estimated amount of insulin to be infused into the body of the user based upon the received data indicative of the blood glucose level of the user. - View Dependent Claims (106, 107, 108, 109, 110, 111, 112, 113, 114)
