Abstract:
1. A method of operating a portable medical device for treatment of diabetes, comprising: receiving at an external reference system housed in a portable controller device a remotely broadcast external reference signal indicative of a standard time and date which is transmitted from a remote time and date reference source; wirelessly receiving at the portable controller device sensor data from a body-worn glucose sensor device that is indicative of a sensed glucose level, the body-worn glucose sensor device including a sensor shaft that penetrates into a subcutaneous layer while a sensor housing is adhered to a skin surface, wherein the portable controller device includes a display to show the sensed glucose level and one or more buttons for user interaction; updating an internal time setting of the portable controller device in response to receiving the remotely broadcast external reference signal; and in response to wirelessly receiving the sensor data indicative of the sensed glucose level, storing in one or more memory devices of the portable controller device a value of the sensed glucose level and a corresponding time and date at which the sensed glucose level was detected based upon the updated internal time setting of the portable controller device.
