Abstract
Systems and methods are disclosed herein for monitoring the status of an ambulatory medical device and the health condition of a subject that receives therapy from the ambulatory medical device. The ambulatory medical device can have a touchscreen display user interface to receive input signals from a user and display alarm conditions associated with the status of an ambulatory medical device or health condition of a subject. The disclosed methods and systems can determine whether status information received from a monitoring system interface satisfies an alarm condition for the ambulatory medicament device or for the subject. If the status information satisfies an alarm condition, the touchscreen user interface can display one or more alarm status indicators corresponding to the alarm condition. The user can activate a therapy change interface on the touchscreen display and modify a control parameter of the ambulatory medical device that controls the therapy delivery to the subject.
Core Innovation
The patent describes a glucose level control system configured to generate a dose output for administration of medicament to a subject. The system receives device or subject status information, determines whether it satisfies an alarm condition, and increments a count of alarm conditions. During a sleep state with reduced power consumption, the system displays the count and annunciates one or more corresponding alarm status indicators, including text information, icons, audible alarms, visual alarms, or haptic alarms.
The described system workflow evaluates status information against alarm conditions, assigns severity to new conditions, and adds them to a pending notification list. Generated user interfaces provide a lock screen interface that prevents a user from inadvertently executing system functions while displaying the alarm count. Furthermore, the interfaces provide access pathways to therapy controls following a wake interaction, wherein indicators are selected, modified, or ceased based on alarm type, severity, or subsequent status information.
Claims Coverage
The claims identify three independent claims comprising two glucose level control system claims and one computer-implemented method claim, encompassing three inventive features.
Alarm count and indicators on a lock screen during sleep
A glucose level control system receives device status information, determines that it satisfies an alarm condition, and increments a count of alarm conditions. While the system is in a reduced-power sleep state and the user interface controller does not receive user input signals, it displays the count on a lock screen interface and annunciates one or more alarm status indicators, including text information, an audible alarm, an icon, a visual alarm, or a haptic alarm.
Computer-implemented alarm annunciation using a lock screen
A computer-implemented method receives device or subject status information, determines that it satisfies an alarm condition, and increments a count of alarm conditions. The method generates a lock screen interface that prevents a user from inadvertently executing one or more functions of the glucose level control system, displays the count on the lock screen, and annunciates one or more corresponding alarm status indicators.
Alarm count and indicators on user interface screens during sleep
A glucose level control system receives device or subject status information, determines that it satisfies an alarm condition, and increments a count of alarm conditions. While the system is in a reduced-power sleep state, it displays the count on one or more user interface screens and annunciates one or more corresponding alarm status indicators.
Together, the independent claims cover system and method implementations that detect alarm conditions in a glucose level control system, increment an alarm count, and display that count while annunciating corresponding indicators. The claims distinguish between displaying alarm counts specifically on a lock screen during sleep, executing a computer-implemented method with inadvertent-function prevention, and presenting counts across user interface screens during sleep.
Stated Advantages
The lock screen interface prevents a user from inadvertently executing one or more functions of the glucose level control system.
Power consumption of the glucose level control system is reduced while operating in the sleep state.
Documented Applications
A glucose level control system configured to generate a dose output for administration of medicament to a subject, including systems comprising an insulin pump or a bi-hormonal pump capable of administering insulin and a counter-regulatory agent.
Ambulatory glucose-control device interfaces for meal announcements, dose limits, manual boluses, and cancellation of pending therapy changes, including alarm notifications accessed through a lock screen.
Display and annunciation of alarm counts and alarm status indicators during the sleep state of a glucose level control system.
