Abstract
Systems and methods are disclosed herein for switching an application executing on an ambulatory medical device to a new application without interrupting therapy provided by the ambulatory medical device to a subject. The ambulatory medical device may receive an indication that an update to an application executing on the ambulatory insulin pump is available, establish a communication connection to a host computing system, download and install the application update, while a prior version of the application continues to run. The disclosed systems and methods can confirm successful installation of the application update on the ambulatory medical device and switch control of the ambulatory medical device from the prior version to the new version of the application without interrupting therapy provided to the subject.
Core Innovation
The disclosure describes methods and a glucose level control system for updating an application that generates a medicament dose output for administration to a subject. The system receives an indication that an update is available, downloads the application update from a host computing system, and confirms that the downloaded copy is complete and not corrupted. Installation is initiated in response to a trigger while maintaining therapy administered to the subject without interruption.
The system can establish a direct end-to-end data connection to a host computing system via a wireless wide area network to download the update. Workflows defer installation or application switching until ongoing therapy is complete and schedule it based on timing before the next delivery, staging a replacement version before control switches to it. The system also supports testing an updated application and switching to an installed safe application version when handling faults.
Claims Coverage
The three independent claims cover two computer-implemented methods and a glucose level control system for updating an application without interrupting therapy, presenting three inventive features.
Verified update over a direct end-to-end wireless connection
A hardware processor of a glucose level control system receives an indication of an available application update, establishes a direct end-to-end data connection to a host computing system via a wireless wide area network, downloads the update, confirms that the downloaded copy is complete and not corrupted, and initiates installation in response to a trigger without interrupting therapy administered to the subject.
Verified update installation without interrupting therapy
A computer-implemented method downloads an application update from a host computing system, confirms that the downloaded copy is complete and not corrupted, receives an installation trigger, and initiates installation without interrupting therapy administered to a subject.
Glucose level control system configured for uninterrupted updating
A glucose level control system comprises memory storing an application and computer-executable instructions, and a hardware processor configured to receive notice of an available application update, download and confirm that the copy is complete and not corrupted, receive an installation trigger, and initiate installation without interrupting therapy.
Together, the independent claims cover update methods and a control system implementation that download and verify an application update and initiate installation while therapy continues without interruption, with one claim reciting a direct end-to-end wireless wide area network connection.
Stated Advantages
The application update can be installed without interrupting therapy administered to the subject.
Documented Applications
Updating an application executing on an ambulatory glucose control device or glucose level control system configured to generate a medicament dose output for administration to a subject, including systems comprising a mono-hormonal or bi-hormonal medicament pump and deferring installation during ongoing therapy.
Handling an application fault by switching to an installed safe application version while another version is sought, downloaded, and installed.
