Abstract

A handheld diabetes managing device that provides a secure and efficient communication link between an insulin pump and an external computing device. The handheld diabetes managing device can include a blood glucose meter, a processor and first and second communication modules. The handheld diabetes managing device can be configured to deliver data between an insulin pump and an external computing device over a secure communication path without a direct communication link between the insulin pump and the external computing device. The secure communication path can include a first secure bidirectional communication link between the handheld diabetes managing device and the insulin pump and a second secure bidirectional communication link between the handheld diabetes managing device and the external computing device.

Claims

wherein the first communication module is further configured to receive a request from the external computing device to establish a pass-through mode with the insulin pump and, in response thereto, initiate a pass-through mode upon detecting the first secure bidirectional communication link, such that the first communication module operates to deliver configuration data received from the external computing device to the insulin pump over a secure communication path without a direct communication link between the external computing device and the insulin pump only when in pass-through mode,

the secure communication path including the first secure bidirectional communication link and the second secure bidirectional communication link.

2. The handheld diabetes managing device of claim 1, wherein the blood glucose data includes one or more of a plurality of blood glucose levels, an amount of food and beverage consumed and associated time of consumption, and an exercise schedule.

3. The handheld diabetes managing device of claim 1, wherein the insulin pump instruction comprises an amount of insulin that is recommended to be delivered by the insulin pump to a patient.

4. The handheld diabetes managing device of claim 3, wherein the insulin pump instruction is further based on at least one of an insulin level received from a continuous glucose monitor, an expected meal, an expected exercise event, the patient'"'"'s insulin resistance, the patient'"'"'s weight and the insulin pump data.

5. The handheld diabetes managing device of claim 4, wherein the insulin pump data includes an amount and time of insulin delivered to the patient during a previous period.

6. The handheld diabetes managing device of claim 1, wherein the first secure bidirectional communication link comprises a wireless communication link.

7. The handheld diabetes managing device of claim 6, wherein the wireless communication link operates in accordance with BLUETOOTH®

wireless technology specification.

8. The handheld diabetes managing device of claim 7, wherein the second secure bidirectional communication link comprises a wired communication link.

9. The handheld diabetes managing device of claim 8, wherein the wired communication link comprises a Universal Serial Bus link.

10. The handheld diabetes managing device of claim 8, wherein the external computing device comprises a personal computer.

11. In a diabetes care system for providing diagnostics and therapy that includes a handheld diabetes managing device, a method of transmitting information between an insulin pump and an external computing device without providing a direct link between the insulin pump and external computing device, comprising:

establishing, by the handheld diabetes managing device, a first secure bidirectional communication link between the handheld diabetes managing device and the insulin pump;

establishing, by the handheld diabetes managing device, a second secure bidirectional communication link between the handheld diabetes managing device and the external computing device;

receiving, by the handheld diabetes managing device, a request from the external computing device to establish a pass-through mode with the insulin pump and initiate a pass-through mode in response thereto;

receiving, by the handheld diabetes managing device, configuration data via the second secure bidirectional communication link from the external computing device; and

transmitting, by the handheld diabetes managing device, the configuration data to the insulin pump over the first secure bidirectional communication link only when in pass-through mode.

12. The method of claim 11, wherein the first secure bidirectional communication link comprises a wireless communication link.

13. The method of claim 12, wherein the wireless communication link operates in accordance with BLUETOOTH®

wireless technology specification.
