Patent ID: 8622954

Claim:
An infusion system to infuse a fluid into a user, the infusion system comprising: a sensor system contained in a sensor housing that includes a sensor to produce a signal indicative of a physiological characteristic of the user, the sensor system further having a sensor processor to process the signal to sensor data, the sensor system further having a sensor receiver and a sensor transmitter, transmissions from the sensor transmitter being processed by the sensor processor and transmitted in a sensor system format; a relay system contained within a relay system housing that includes a first relay receiver to receive sensor data in the sensor system format and a second relay receiver, the relay system further having a relay system processor to convert the sensor system format to a delivery system format, the relay system further having a first relay transmitter to transmit sensor data in the delivery system format and a relay system user interface, the relay system user interface being used to control a second relay transmitter to transmit communications to the sensor receiver; and a delivery system contained within a delivery system housing that includes a delivery system receiver to receive transmissions from the first relay transmitter in the delivery system format, the communications received in the delivery system format being processed by a delivery system processor to determine an amount of fluid to be infused into the user, the delivery system further including a delivery system transmitter, wherein manipulation of the relay system user interface prompts the delivery system transmitter to send a request to the sensor system for sensor data through the second relay receiver and second relay transmitter, the relay system user interface further configured to send commands to the delivery system.
