Abstract

Systems and methods are disclosed for adjusting the delivery times of an insulin delivery profile of an insulin pump, wherein the insulin pump is operable to automatically deliver insulin to a person having diabetes based on an operating time of the internal clock and a delivery time of an insulin delivery profile. The method may comprise receiving a local time zone time from an external local clock, determining whether the operating time of the internal clock differs from the local time zone time by at least a first predetermined amount of time, requesting the person provide a time adjustment value when the operating time of the internal clock differs from the local time zone time by at least the first predetermined amount of time, receiving the time adjustment value from the person, and adjusting the delivery times of the insulin delivery profile based on the time adjustment value when received.

9. The insulin pump of claim 8, wherein the second predetermined amount of time is 24 hours.

10. The insulin pump of claim 1, wherein the processor is configured to record a time-stamp of both the local time zone time and the operating time upon causing the delivery module to deliver the insulin to the person.

11. The insulin pump of claim 1, wherein at least one of the one or more delivery times of the insulin delivery profile is a basal rate delivery time, and the basal rate delivery time is adjusted when the insulin delivery profile is adjusted.

12. A system for automatically delivering insulin to a person having diabetes and configured to receive at least a local time zone time from an external local clock, the system comprising:

an insulin pump having;

an internal clock providing an operating time,

a delivery module for delivering the insulin to the person according to an insulin delivery profile comprising one or more delivery times,

memory storing the insulin delivery profile, and

a first processor in electrical communication with the internal clock, the memory for reading the insulin delivery profile, and the delivery module; and

a blood glucose (bG) meter in communication with the insulin pump via a wireless communication link, the bG meter having an input device, a display, a wireless communication module, and a second processor in electrical communication with the input device, the display, the wireless communication module, wherein;

the second processor;

receives the operating time of the internal clock of the insulin pump via the wireless communication link,

receives the local time zone time from the external local clock via the wireless communication module or from the person via the input device,

determines whether times of the local time zone time and the operating time differ by at least a first predetermined amount of time,

displays a request on the display for a time adjustment value from the person representing an amount of time to adjust the one or more delivery times of the insulin delivery profile when the operating time of the internal clock differs from the local time zone time by at least the first predetermined amount of time,

receives the time adjustment value via the input device,

sends the time adjustment value when received to the insulin pump via the wireless communication link, and

the first processor adjusts the one or more delivery times of the insulin delivery profile based on the time adjustment value sent from the bG meter.

13. The system of claim 12, wherein the external local clock is derived from a global positioning system, a wireless computer network, a cellular network, another blood glucose meter, or a smart phone.
