Abstract

The exemplary embodiments may detect the changed ambient air pressure and may adjust settings for the medicament delivery device to compensate for the changed ambient air pressure. The exemplary embodiments may detect the changed ambient air pressure and may adjust settings for the medicament delivery device to compensate for the changed ambient air pressure. Based on the detection of these events, the medicament delivery device may be switched into a flight mode. In the flight mode, medicament boluses may be reduced to nominal dosages, basal delivery rates may be modified and sample periods for sensors, like glucose monitors, may be shortened to sample sensor values more frequently. The exemplary embodiments may prohibit delivery of medicament during times of changing ambient air pressure to avoid over-delivering or under-delivering the medicament due to the ambient air pressure level.

Core Innovation

The claims describe a method, a non-transitory storage medium, and a medicament delivery system that determine when a user of a medicament delivery device is on an airplane flight. In response to determining the flight, the system switches the basal delivery rate from a normal mode rate to a different flight mode rate to adapt for at least one environmental condition due to the flight. Following landing detection, the processor switches to a distinct cool off mode basal delivery rate for a cool off period.

The cool off mode basal delivery rate aids the transition back to the normal mode basal delivery rate. Flight status and landing detection utilize sensor, location, calendar, barometric pressure, or network data, including accelerometer landing-signature matching and optional user confirmation before mode switching. The disclosure further describes modified basal and bolus delivery under reduced air pressure and acceleration. Because the background section is omitted from the partial content, the stated problem is not explicitly described.

Claims Coverage

There are three independent claims: claim 1 covers a method, claim 9 covers a non-transitory storage medium, and claim 15 covers a medicament delivery system. The three inventive features correspond to these independent claims.

The independent claims cover flight-responsive basal delivery rate adjustments and post-landing cool-off transitions embodied as a method, stored instructions, and a medicament delivery system. Dependent claims further recite flight-status data sources, user confirmation, reduced-air-pressure delivery adjustments, insulin, cool-off durations, and conditioning cool-off on travel across multiple time zones.
