Patent ID: 7278983

Claim:
An infusion system for infusing a fluid into a body of a user, the infusion system comprising: a physiological monitoring device comprising: a monitoring device processor; a sensor coupled to the monitoring device processor and adapted to provide an output signal as a function of a concentration of an analyte in the user; and a monitoring device communication circuit coupled to the monitoring device processor; wherein the monitoring device processor is adapted to: determine a first amount of time that has elapsed since the sensor provided the output signal; determine whether the first amount of time exceeds a predetermined amount of time; and, if the first amount of time does not exceed a predetermined amount of time, calculate an amount of the fluid to be infused into the user's body based upon the output signal, and cause the monitoring device communication circuit to transmit a first set of data indicative of the calculated amount of the fluid to be infused; wherein the monitoring device communication circuit does not transmit a set of data indicative of a calculated amount of fluid to be infused into the user's body based upon the output signal if the first amount of time exceeds the predetermined amount of time; and a medication infusion device comprising: an infusion device processor; a drive mechanism coupled to the infusion device processor and adapted to infuse the fluid into the body of the user; and an infusion device communication circuit coupled to the infusion device processor and adapted to receive the first set of data from the monitoring device communication circuit; wherein the infusion device processor is adapted to cause the drive mechanism to infuse the fluid into the body of the user in accordance with the first set of data indicative of the calculated amount of the fluid to be infused; and wherein the physiological monitoring device is adapted to be carried by the user on an exterior of the body of the user and the medication infusion device is adapted to be carried by the user on an exterior of the body of the user.
