Abstract

Apparatus are provided for medical devices and related operating systems and methods. An exemplary medical device includes a motor, one or more data storage elements to maintain control information, and a control module coupled to the motor and the one or more data storage elements. The control module is configured to obtain updated control information via a peer-to-peer communication session over a network, store the updated control information in the one or more data storage elements, and thereafter operate the motor based at least in part on the updated control information.

First claim

What is claimed is:

1. A medical device comprising:
a receiver to receive measurement data indicative of a condition of a user;
one or more data storage elements to store the measurement data and network identification information for authenticating an intermediate device paired with the medical device; and
a control module coupled to the one or more data storage elements to periodically initiate a temporary communication session with the intermediate device over a network and automatically transmit the measurement data to the intermediate device via the temporary communication session in response to receiving an acknowledgement establishing the temporary communication session from the intermediate device, wherein the intermediate device automatically provides the acknowledgment in response to receiving a second acknowledgement from a remote device establishing a second temporary communication session between the intermediate device and the remote device over a second network distinct from the network and the intermediate device streams the measurement data to the remote device via the second temporary communication session without permanently storing the measurement data.

2. The medical device of claim 1 , wherein:
the one or more data storage elements buffer the measurement data over a duration of time; and
the control module determines to autonomously initiate the temporary communication session when the duration of time has elapsed.

3. The medical device of claim 2 , wherein:
the one or more data storage elements buffer delivery data corresponding to the duration of time; and
the control module automatically transmits the delivery data to the intermediate device via the temporary communication session along with the measurement data.

4. The medical device of claim 1 , further comprising a timer supporting autonomously uploading the measurement data on a periodic basis.

5. The medical device of claim 1 , wherein the control module autonomously terminates the temporary communication session after transmitting the measurement data.

6. The medical device of claim 5 , wherein the control module requires the intermediate device provide a confirmation the measurement data has been removed from the intermediate device prior to terminating the temporary communication session.

7. The medical device of claim 1 , further comprising a transceiver module, wherein the control module periodically initiates the temporary communication session by transitioning the transceiver module from a low power mode to an active mode.

8. The medical device of claim 1 , wherein the control module initiates the temporary communication session by transmitting a connection request to the intermediate device via the network.

9. A medical device comprising:
a receiver to receive measurement data indicative of a condition of a user;
a motor operable to deliver a fluid influencing the condition of the user;
one or more data storage elements to maintain control information and store the measurement data and network identification information for authenticating an intermediate device paired with the medical device; and
a control module coupled to the one or more data storage elements to periodically initiate a temporary communication session with the intermediate device over a network and automatically transmit the measurement data to the intermediate device via the temporary communication session in response to receiving an acknowledgement establishing the temporary communication session from the intermediate device, wherein the control module is coupled to the motor to autonomously operate the motor to deliver the fluid based at least in part on the control information and one or more measured values of the measurement data to autonomously regulate the condition, automatically establish a second temporary communication session with the intermediate device over the network in response to a request from the intermediate device, obtain updated control information from the intermediate device via the second temporary communication session, overwrite the control information in the one or more data storage elements with the updated control information to store the updated control information in the one or more data storage elements, and after the control information is updated, autonomously operate the motor based at least in part on the updated control information and one or more subsequent measured values for the condition of the user to autonomously regulate the condition.

10. The medical device of claim 9 , wherein the updated control information is determined based at least in part on the one or more measured values obtained while the control module operates the motor based on the control information.

11. The medical device of claim 9 , wherein operation of the motor based on the control information influences the one or more measured values.

12. The medical device of claim 9 , wherein the updated control information comprises an updated gain coefficient for a proportional-integral-derivative control implemented by the control module.

13. The medical device of claim 9 , wherein the updated control information comprises application code executed by the control module to determine delivery commands for operating the motor.

14. A method of operating a medical device, the method comprising:
receiving, at the medical device, measurement data indicative of a physiological condition of a user provided by a sensing arrangement;
autonomously determining, at the medical device, whether to upload the measurement data to a remote device on a periodic basis;
in response to determining the measurement data should be uploaded:
autonomously initiating, by the medical device, a temporary communication session with an intermediate device over a network;
receiving, at the medical device, an acknowledgement establishing the temporary communication session from the intermediate device, wherein the intermediate device automatically provides the acknowledgment in response to receiving a second acknowledgement from the remote device establishing a second temporary communication session between the intermediate device and the remote device over a second network distinct from the network; and
automatically transmitting, by the medical device, the measurement data to the intermediate device via the temporary communication session, wherein the intermediate device streams the measurement data to the remote device via the second temporary communication session without permanently storing the measurement data.

15. The method of claim 14 , further comprising buffering the measurement data over a duration of time, wherein autonomously initiating the temporary communication session comprises autonomously initiating the temporary communication session on the periodic basis when the duration of time has elapsed.

16. The method of claim 14 , further comprising autonomously terminating, by the medical device, the temporary communication session after transmitting the measurement data.

17. The method of claim 16 , wherein autonomously terminating the temporary communication session comprises:
transmitting, by the medical device, a termination request to the intermediate device; and
automatically transitioning a transceiver module of the medical device to a low power mode in response to receiving a confirmation from the intermediate device indicating the measurement data has been deleted from the intermediate device.

18. The method of claim 14 , further comprising performing a termination procedure that requires the
