Abstract

A diabetes management system is provided that supports connectivity of applications residing on a medical device. The diabetes management system includes a medical device that performs a diabetes care function in relation to a patient and a diabetes care management device in data communication with the medical device. The diabetes care management device is comprised generally of a connection management module and at least one application separate from the connection management module. The connection management module is configured to receive an associate request from the medical device and operable to establish a data connection with the medical device in accordance with IEEE standard 11073, such that the applications interacts with the connection management module to communicate via the data connection with the medical device.

Claims

1. A computer-implemented diabetes management system that supports connectivity of applications residing on a medical device, comprising:

a medical device that performs a diabetes care function in relation to a patient and stores data pertaining to the function;

a diabetes care management device in data communication with the medical device and further includes;

a connection management module configured to receive an associate request from the medical device and operable to establish a data connection with the medical device in accordance with IEEE standard 11073;

a first application separate from the connection management module and residing on the diabetes care management device, wherein the first application interacts with the connection management module to communicate via the connection with the medical device, wherein the first application acquires a reference to a remotable object from the connection management module and instantiates the remotable object, such that the remotable object exposes methods which allow the first application to communicate with the connection management module; and

the diabetes management system further comprises a listing of devices interoperable with the diabetes care management device and accessible to the connection management module, wherein, upon receipt of an associate request, the connection management module queries the listing of devices and establishes the data connection when the associate request is received from a medical device on the listing of devices.

2. The computer-implemented diabetes management system of claim 1 wherein the connection management module operates to disassociate from the medical device when the medical device is not on the listing of devices.

3. The computer-implemented diabetes management system of claim 1 wherein the connection management module receives a registration request from the first application for the data connection with the medical device and registers the data connection for use by the first application.

4. The computer-implemented diabetes management system of claim 3 wherein the connection management module receives messages over the data connection from the medical device and routes the messages to the first application.

5. The computer-implemented diabetes management system of claim 3 further comprises a listing of devices interoperable with the diabetes care management device and accessible to the first application, wherein the first application queries the listing of devices and establishes the data connection when the associate request is received from a medical device on the listing of devices.

6. The computer-implemented diabetes management system of claim 1 wherein the connection management module is configured to receive data over the data connection from the medical device and store the data for subsequent access by a client application in a transient data store accessible to the connection management module.

7. The computer-implemented diabetes management system of claim 1 wherein wherein the connection management module establishes an inter-process communication (IPC) channel for communication with the first application.

8. The computer-implemented diabetes management system of claim 1 wherein the connection management module communicates with the first application in accordance with the .NET framework.

9. A diabetes care management device that supports contention resolution amongst applications residing thereon, comprising:

a connection management module configured to receive an associate request from a medical device and, in response to the associate request, operate to establish a data connection with the medical device in accordance with IEEE standard 11073, wherein the connection management module includes a remotable object such that the remoteable object exposes methods which allow applications to communicate with the connection management module;

a first application separate from the connection management module and residing on the diabetes care management device, wherein the first application interacts with the connection management module to communicate via the connection with the medical device;

a second application separate from the connection management module and residing on the diabetes care management device, wherein the second application interacts with the connection management module to communicate via the connection with the medical device; and

a contention manager configured to receive a request to access the data connection from both the first and second application and operable to grant access to one of the first application or the second application in accordance with an access rule, wherein the connection management module and the contention manager are implemented as non-transitory computer-readable storage medium having stored thereon, computer-executable instructions executed by a computer processor.

10. The diabetes care management device of claim 9 wherein the contention manager operates to deny access to the other of the first application or the second application in accordance with the access rule.

11. The diabetes care management device of claim 9 wherein the connection management module receives a registration request from the first application for the data connection with the medical device and registers the data connection for use by the first application.

12. The diabetes care management device of claim 11 wherein the connection management module receives messages over the data connection from the medical device and routes the messages to the first application.

13. The diabetes care management device of claim 11 wherein the connection management module receives a registration request from the second application for the data connection with the medical device while the data connection is registered for use by the first application and denies the registration request from the second application.

14. The diabetes care management device of claim 11 wherein the connection management module receives a registration request from the second application for the data connection with the medical device while the data connection is registered for use by the first application, unregisters the data connection for use by the first application and registers the data connection for use by the second application.

15. The diabetes care management device of claim 9 wherein the connection management module establishes an inter-process communication (IPC) channel for communication with the first application.

16. The diabetes care management device of claim 15 wherein the first application operates over the IPC channel to acquire a reference to a remotable object from the connection management module and instantiates the remotable object, where the remotable object exposes methods which allow the first application to communicate with the connection management module.
