First Claim
Patent Images
1. 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, andcause 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.

Abstract
Methods and apparatuses for calculating and transmitting medication dosage or bolus information are provided. A blood glucose meter receives a test strip with a sample of the user'"'"'s blood and measures the user'"'"'s blood glucose level with a sensor. The meter then calculates a bolus amount that is transmitted to a medication infusion pump using a radio frequency transmitter or transceiver. The infusion pump receives the bolus amount data and then delivers a bolus of medication to the user based on the calculated bolus estimate. The meter may also transmit commands to, and be used to remotely control, the infusion pump.
