Abstract

One or more embodiments relate, generally, to a reusable accessory for a medication injection pen. Such a reusable accessory may be adapted to be reversibly attached to a medication injection pen, and configured to detect an event associated with an injection of medication from the medication injection pen. It may also be configured to determine a percentage of medication that remains active for injection by the medication injection pen based on timing information and dosing event information.

Core Innovation

The invention provides an accessory for an injection pen that includes a display and a controller. The controller detects dosing events associated with the injection pen and, responsive to a most recent dosing event, changes a displayed appearance of the display from a first displayed appearance to a second displayed appearance. The accessory thereby provides therapy information using a change in displayed appearance tied to dosing events.

In related embodiments, the invention is implemented as a pen cap for a medication delivery device. The pen cap includes an indicator configured to indicate therapy data to a user and a controller that detects attachment of the pen cap to the medication delivery device or detachment from the medication delivery device. Responsive to the attachment or detachment, the controller changes the displayed appearance of at least a portion of the indicator from a first displayed appearance to a second displayed appearance.

The system also supports managing therapy for a person by combining the accessory with a therapy management application in wireless communication. The accessory detects capping or decapping of the accessory from the medication delivery device and changes at least a portion of one or more indicator appearances from a first displayed appearance to a second displayed appearance. The therapy management application performs therapy management using received events and, in some embodiments, provides dose reminders and alerts based on therapy data or dosing data, including notification behaviors and event-logging control using disregard rules for short capping/decapping events.

Claims Coverage

The independent claims cover four core aspects: (i) a pen-injection accessory that detects dosing events and changes a display appearance, (ii) a pen cap that detects cap attachment/detachment and changes an indicator appearance, (iii) a method that delivers medication by changing a pen-cap UI appearance responsive to capping/uncapping, and (iv) a therapy management system that uses wireless communication to detect capping/decapping and change indicator appearances while enabling application-level therapy management.

Accessory with therapy display that changes appearance responsive to dosing events

Detecting dosing events associated with the injection pen; and responsive to a most recent dosing event, changing a displayed appearance of the display from a first displayed appearance to a second displayed appearance.

Pen cap detects cap attachment/detachment and changes indicator appearance

Detecting attachment of the pen cap to the medication delivery device or detachment of the pen cap from the medication delivery device; and responsive to the pen cap being attached to or detached from the medication delivery device, changing a displayed appearance of at least a portion of the indicator from a first displayed appearance to a second displayed appearance.

Method of delivering medication with pen-cap UI appearance change responsive to capping/uncapping

Responsive to a pen cap being capped on or uncapped from an injection pen, changing a displayed appearance of at least a portion of a user interface of the pen cap from a first displayed appearance to a second displayed appearance.

Therapy management system detecting capping/decapping and changing indicator appearance in wireless communication

Detecting at least one of a capping or a decapping of the accessory from the medication delivery device; and responsive to the accessory being capped on or uncapped from the medication delivery device, changing a at least a portion of the one or more indicators from a first displayed appearance to a second displayed appearance.

Across the independent claims, the key inventive coverage centers on detecting capping/decapping (or pen-cap attachment/detachment) and responsively changing displayed appearances (display or indicator) to convey therapy information, with system-level embodiments additionally supporting therapy management application functions in wireless communication.
