Abstract
Some embodiments of a portable medical device, such as an infusion pump, can receive an external reference signal (e.g., a radio, cellular and/or satellite signal) to provide an automatic time-setting and maintenance operation. In these circumstances, the medical device can maintain accurate time and date information even in the event of a power interruption, a time-zone change and/or an internal clock error, for example. In this manner, the portable medical device provides safe operation and added convenience to the user.
Claims25
A method of operating a portable infusion pump system, comprising:
- receiving at a portable infusion pump system an external reference clock signal that is broadcast from a remote time reference source, the external reference clock signal being indicative of a standard time and a standard date;
- automatically updating at predetermined intervals a time setting of the portable infusion pump system based on the external reference clock signal to provide an updated time, the updated time being presented on a user interface display of the portable infusion pump system;
- in response to the updated time setting being different from a previous time setting by a predetermined threshold, alerting a user via the user interface display that the updated time is detected;
- and
- after alerting the user via the user interface display, receiving user input that authorizes a change to an operation of the portable infusion pump system based on the updated time setting.

A portable diabetes treatment device, comprising:
- an external reference system that receives an external reference signal broadcast from a remote time reference source, the external reference signal being indicative of a standard time and a standard date;
- and
- a controller device that updates a time setting of the portable diabetes treatment device based on the external reference signal to provide an updated time setting,
- wherein the controller device operates the portable diabetes treatment device based on the updated time setting.

A portable diabetes treatment device, comprising:
- an external reference system that receives an external reference signal broadcast from a remote time reference source, the external reference signal being indicative of a standard time;
- and
- a controller device that updates a time setting of the portable diabetes treatment device based on the external reference signal to provide an updated time setting, wherein the portable diabetes treatment device comprises a glucose monitoring system that communicates sensor data to the controller device, and the controller device recording the sensor data along with an associated time-stamp based on the updated time setting,
- wherein the controller device operates the portable diabetes treatment device based on the updated time setting.

A wearable infusion pump system, comprising:
- a disposable and non-reusable pump device including a drive system to dispense medicine from the pump device, the pump device having a first electrical connector that is externally accessible;
- a reusable controller device removably attachable to the disposable and non-reusable pump device, the controller device comprising:
- a second electrical connector that is engageable with the first connector to provide electrical communication between control circuitry of the controller device and the drive system of the pump device;
- a user interface comprising a display device, the user interface being electrically connected to the control circuitry
- an external reference system that receives an external reference signal broadcast from a remote time reference source, the external reference signal being indicative of a standard time, the external reference system being electrically connected to the control circuitry;
- and
- a processor that updates a time setting of the infusion pump system based on the external reference signal to provide an updated time setting;
- wherein the reusable controller activates the drive system of the pump device based on the updated time settings,
- wherein the reusable controller device activates the drive system of the pump device according to a dispensing rate schedule based on time of day,
- wherein the reusable controller device indicates a time-zone change based on the external reference signal and shifts the dispensing rate schedule based on the time-zone change, and
- wherein the user interface queries a user to confirm whether operation of the wearable infusion pump system should be adjusted based on the time-zone change, and wherein the dispensing rate schedule shifting based on the time-zone change is only executed in response to input to the user interface.
