Abstract

Systems and methods are provided for updating medical devices. An exemplary system includes a medical device and a remote device. The medical device is operable to regulate a condition of a user. The remote device receives measurement data correlative to the condition of the user, determines control information for the medical device based at least in part on the measurement data, and transmits the control information via a first peer-to-peer communication session. The medical device receives the control information via a second peer-to-peer communication session and thereafter regulates the condition of the user based at least in part on the control information and subsequent measurement data.

6. The system of claim 1, wherein:

the control information includes a target value for the condition of the user and one or more control parameters;

the subsequent measurement data comprises one or more measured values correlative to the condition of the user; and

the medical device regulates the condition of the user based on the one or more control parameters and a difference between the target value and the one or more measured values.

7. The system of claim 1, wherein:

the medical device establishes a third peer-to-peer communication session on a first communications network and transmits the measurement data via the third peer-to-peer communication session;

the remote device receives the measurement data via a fourth peer-to-peer communication session on a second communications network; and

after determining the control information;

the remote device establishes the first peer-to-peer communication session on the second communications network; and

the medical device receives the control information via the second peer-to-peer communication session on the first communications network.

8. The system of claim 1, wherein:

the medical device uploads the measurement data and delivery data characterizing delivery of a fluid to the user, the fluid influencing the condition of the user; and

the remote device determines the control information based at least in part on the measurement data and the delivery data.

9. The system of claim 8, wherein:

the medical device uploads the subsequent measurement data and subsequent delivery data;

the remote device receives the subsequent measurement data and the subsequent delivery data, determines updated control information for the medical device based at least in part on the subsequent measurement data and the subsequent delivery data, and transmits the updated control information; and

the medical device receives the updated control information and thereafter regulates the condition of the user based on the updated control information.

10. The system of claim 1, wherein the medical device comprises an infusion device including:

a motor operable to deliver fluid to the user, the fluid influencing the condition of the user;

one or more data storage elements to maintain the control information; and

a control module coupled to the motor and the one or more data storage elements to operate the motor based on the control information and the subsequent measurement data to regulate the condition of the user.

11. A method of updating a medical device, the method comprising:

uploading measurement data from the medical device to a remote device, the measurement data comprising one or more measured values correlative to a condition of a user associated with the medical device;

determining, by the remote device based at least in part on the measurement data, control information for regulating the condition of the user;

initiating a peer-to-peer communication session with the medical device over a network; and

providing the control information to the medical device via the peer-to-peer communication session.

12. The method of claim 11, further comprising operating the medical device to regulate the condition of the user in accordance with the control information.
