COEXISTENCE OF MULTIPLE RADIOS IN A MEDICAL DEVICE

摘要

A computer-implemented diabetes management system is provided that supports enhanced security between a diabetes care manager in data communication with a medical device. The diabetes care manager includes: a first application that operates to request access to a first security role supported by the medical device, where the first security role is associated with a first set of commands for accessing data on the medical device that are defined as a private extension of the communication protocol; and a second application that operates to request access to a second security role supported by the medical device, where the second security role is associated with a second set of commands for accessing data on the medical device that are defined as a private extension of the communication protocol. The second set of commands has one or more commands that are mutually exclusive from the first set of commands.

主权项

1. A handheld diabetes management device that arbitrates priority among multiple communication modules having a shared antenna for communicating with a plurality of medical devices, the handheld diabetes management device comprising:
a blood glucose measuring module that selectively measures blood glucose in a blood sample; a first communication module that selectively communicates in a first frequency band with an insulin infusion pump external to the handheld diabetes management device via a first antenna using a first wireless communication protocol; a second communication module that selectively communicates in the first frequency band with a continuous glucose monitor external to the handheld diabetes management device via the first antenna using a second wireless communication protocol; and an arbitration module that receives signals from the first and second communication modules for concurrent communication with the insulin infusion pump and the continuous glucose monitor, respectively, identifies the insulin infusion pump and the continuous glucose monitor as the source or destination of the signals, determines that the insulin infusion pump has a higher priority than the continuous glucose monitor, and grants permission to communicate to the first communication module, and denies permission to communicate to the second communication module.
