Abstract

A system and method of processing information regarding medical devices in wireless communication with each other is provided in which a handheld device has a first wireless communication link with a first medical device, such as a glucose sensor, and a second wireless communication link with a second medical device, such as an insulin pump. A processor in the handheld device monitors the status of the first and second wireless links and upon noting a change in status of either one, compares the first wireless link status with the second wireless link status and provides guidance for resolving a communication problem based on the comparison. The latency of the medical devices is considered as well as the ability to make system status changes, extend time periods before alarms are issued, and the characteristics of the medical devices are considered.

Claims

1. A system of processing information regarding medical devices in wireless communication with each other, the system comprising:

a base device having a first wireless communication link with a first medical device and a second wireless communication link with a second medical device; and

the base device having a processor configured to monitor the status of the first wireless link and the status of the second wireless link;

wherein the base device processor is further configured to determine if a problem exists with one or more of the first and second links; and

wherein the base processor is further configured to compare the first wireless link status with the second wireless link status in the event that a problem with one or more of the monitored links is detected, and to provide guidance for resolving the problem based on the comparison.

2. The system of claim 1, wherein the processor is further configured to display the guidance on a visual display.

3. The system of claim 1, wherein the processor is further configured to determine that a link problem does not exist if the monitored link status lies within a latency of the respective medical device.

4. The system of claim 1, wherein the processor is further configured to cause a system change to occur based on the comparison.

5. The system of claim 4, wherein the processor is further configured to control the base device to cease monitoring a link based on the comparison, whereby power of the base unit is conserved.

6. The system method of claim 1, wherein the processor is further configured to make a determination of link status based on a selected time period and on at least one characteristic of the respective medical device.

7. The system method of claim 6, wherein the processor is further configured to issue an alarm based on the comparison and the selected time period.

8. The system method of claim 7, wherein the processor is further configured to extend the time period based on the comparison, before an alarm is provided.

9. The system of claim 1, wherein the processor is further configured to determine the status of at least one of the medical devices based on the link comparison.

10. The system of claim 1, wherein the processor is further configured to monitor the communication links to identify the existence of an intermittent communication link, and to consider the intermittent link in the comparison.

11. The system of claim 1, wherein:

each of the medical devices are battery powered and the base station comprises a handheld battery-powered device; and

the processor is further configured to initiate a system status change based at least in part on conserving battery power.

12. A method of processing information regarding a base station having a first wireless communication link with a first medical device and having a second wireless communication link with a second medical device, the method comprising:

monitoring each communication link;

detecting a problem in at least one of the communication links being monitored;

determining if a problem exists with one or more of the monitored communication links;

comparing the status of the monitored communication links with each other in the event that a problem appears to exist with one of the communication links; and

providing guidance based on the link comparison for resolving the problem.

13. The method of claim 12, further comprising displaying the guidance on a visual display.

14. The method of claim 12, further comprising determining that a link problem does not exist if the monitored link status lies within a latency of the respective medical device.

15. The method of claim 12, further comprising changing the system status based on the comparison.

16. The method of claim 15, further comprising controlling the base device to cease monitoring a link based on the comparison, whereby power of the base unit is conserved.

17. The method of claim 12, further comprising making a determination of link status based on a selected time period and on at least one characteristic of the respective medical device.

18. The method of claim 17, further comprising issuing an alarm based on the comparison and the selected time period.

19. The method of claim 18, further comprising extending the time period based on the comparison, before an alarm is provided.

20. The method of claim 12, further comprising determining the status of at least one of the medical devices based on the link comparison.

21. The method of claim 12, further comprising monitoring the communication links to identify the existence of an intermittent communication link, and considering the intermittent link in the comparison.
