Abstract

In one embodiment, a diabetes management system comprises a glucose monitoring system, a pump system, and a remote device. The glucose monitoring system and pump system are attached to a patient and covered by a soft shell. The glucose monitoring system and the pump system are controlled by the small, touch-screen remote device such a patient can discreetly monitor blood glucose levels and administer insulin dosages. The remote device has a small and durable form factor that can be worn or carried in various ways.

Claims

1. A method for dosing a patient with insulin, comprising:

wirelessly receiving at a remote device a blood glucose level of a patient;

calculating at the remote device an insulin dosage to be administered; and

wirelessly transmitting from the remote device the insulin dosage to be administered to the patient.

2. A method of claim 1, wherein said blood glucose level of a patient is wirelessly received from one or more blood glucose monitoring systems distinct from the remote device, and the insulin dosage to be administered is transmitted to a pump system distinct from the remote device.

3. A method of claim 2, further comprising:

measuring a patient'"'"'s blood glucose level at the glucose monitoring system attached to a patient;

wirelessly transmitting the patient'"'"'s blood glucose level from the glucose monitoring system to the remote device;

wirelessly receiving at the pump system from the remote device the insulin dosage to be administered; and

administering insulin corresponding to the insulin dosage to be administered to the patient at the pump system.

4. A method of claim 1, wherein said wirelessly transmitting and said wirelessly receiving are to and from a single pump-monitor system.

5. A method of claim 1, further comprising, prior to said calculating:

determining at the remote device a suggested insulin dosage based on said blood glucose level and a patient profile, which includes historical blood glucose levels, stored on the remote device.

6. A method of claim 5, wherein the insulin dosage to be administered is the suggested insulin dosage.

7. A method of claim 5, wherein determining the insulin dosage to be administered further comprises receiving patient instructions selected from a group consisting of:

instructions to modify, accept, or reject the suggested insulin dosage.

8. A method of claim 5, further comprising, prior to said determining at the remote device a suggested insulin dosage:

determining if a dosage cycle trigger level has reached a threshold;

if said dosage cycle trigger level has reached a threshold, initiating a dosage cycle;

if said dosage cycle trigger level has not reached a threshold, performing no further operations.

9. A method of claim 8, wherein the pre-determine dosage cycle trigger level is selected from the group consisting of:

a blood glucose level, a time of day, a period of time since a previous insulin dosage, and an alert message.

10. A method of claim 1, further comprising, prior to said calculating:

receiving from a patient an instruction to begin said calculating.

11. A method of claim 10, wherein said patient instructions are selected from the group consisting of:

an instruction to begin an automatic dosage calculation, patient inputted insulin dose, and patient inputted units of carbohydrates.

12. A method of claim 10, wherein said instruction includes a patient desired insulin dosage, further comprising, prior to said wirelessly transmitting:

comparing said patient desired insulin dosage to said insulin dosage to be administered and obtaining a difference; and

if said difference reaches a pre-determined warning trigger level, returning a patient specific warning;

if said difference does not reach a predetermined warning trigger level, displaying said patient desired insulin dosage as a calculated insulin dosage to be administered.

13. A method of claim 1, further comprising, prior to said calculating:

comparing the blood glucose level to a previous blood glucose level; and

displaying a blood glucose level trending data in a format selected from a group consisting of;

a trending arrow, a trending graph, a change in an ambient display, and any combination of the aforementioned.

18. A method of claim 1, wherein said wirelessly receiving activates an alert if the blood glucose level reaches below a predetermined blood glucose alert level, where said alert is in a format selected from a group consisting of:

a visual alert, a haptic alert, an audio alert, and any combination of the aforementioned.

19. A method of claim 1, wherein said wirelessly receiving activates an alert if a technical problem occurs;

said technical problem is selected from a group consisting of;

a low insulin level in a reservoir, a malfunction in the blood glucose monitoring system, a malfunction in the pump system, the pump is disconnected from a cannula, a cannula is disconnected from a needle, the remote device is out of range with the blood glucose monitoring system, and the remote device is out of range with the pump system.

20. A method of claim 5, wherein said suggesting is at least partially based on a patient specified mode selected from the group consisting of:

a sleep mode, a rest mode, an exercise mode, a work mode, a school mode, an eating mode, and a default mode.

21. A method of claim 1, further comprising,

sending a patient profile to an external computing device for tracking long term trends, tracking trends in various modes, or assisting patients in goal setting.

14. A method of monitoring a patient'"'"'s blood glucose levels, comprising:

receiving at a remote device a blood glucose level of a patient;

comparing the blood glucose level to one or more previous blood glucose levels of the patient; and

displaying a blood glucose level trending data as a change in an ambient display.

15. A method of claim 14, wherein the change in ambient display presents a positive display image when trending in a normal range and a negative display image when trending outside of, or nearly outside of, the normal range.

16. A method of claim 15, wherein the positive and negative displays are selected from a group consisting of:

a darker sky when trending outside of the normal range and a lighter sky when trending in the normal range, an unhappy digital pet when trending outside of the normal range and a happy digital pet when trending in the normal range, a warm color when trending outside of the normal range and a cool color when trending in the normal range, and any combination of the aforementioned.

17. A method of claim 14, further comprising:

storing the patient'"'"'s blood glucose level in a patient profile along with one or more of the following pieces of information;

time, date, and mode, insulin dose, previous carbohydrate consumption guess, the amount of the previous dose, the time since the previous dose, and any warnings or alerts that were given.

22. A diabetes management method, said method comprising:

measuring a patient'"'"'s blood glucose level at a glucose monitoring system attached to a patient;

wirelessly transmitting the patient'"'"'s blood glucose level from the glucose monitoring system to a remote device;

wirelessly receiving at the remote device the blood glucose level of the patient;

comparing the blood glucose level to a previous blood glucose level;

displaying a blood glucose level trending data on the remote device;

simultaneously displaying the blood glucose level on the remote device;

comparing the blood glucose level to a pre-determined dosage cycle trigger level;

determining whether to initiate a suggested dosage cycle based on said comparing;

determining at the remote device a suggested insulin dosage based on the blood glucose level and a patient profile, which includes historical blood glucose levels, stored on the remote device;

calculating at the remote device an insulin dosage to be administered;

receiving instructions from the patient to transmit said insulin dosage to be administered;

wirelessly transmitting from the remote device to a pump system attached to a patient the insulin dosage to be administered;

wirelessly receiving at the pump system from the remote device the insulin dosage to be administered; and
