Summary of the Inventive Concept

The inventive concept adapts the automatic detection of un-bolused meals for specific, narrow markets or unique operational environments, such as extreme weather conditions, high-security needs, or disaster relief situations.

Background and Problem Solved

The original patent's automatic detection of un-bolused meals has limitations in addressing the needs of users in extreme environments. The new inventive concept addresses these limitations by adapting the system for use in extreme weather conditions, high-security environments, and disaster relief situations.

Detailed Description of the Inventive Concept

The inventive concept comprises a portable infusion pump, a continuous glucose monitoring system, and a processing unit that monitors CGM data and provides a reminder to deliver a meal bolus if the CGM data exceeds a predetermined threshold during a time period. In extreme weather conditions, the processing unit adjusts the threshold based on weather data received from a remote weather service. In high-security environments, the reminder is encrypted and transmitted to the user's device, which is authenticated using a secure authentication protocol including a biometric authentication step. In disaster relief situations, the portable infusion pump is configured to operate for an extended period of time using a battery-powered backup system.

Novelty and Inventive Step

The new inventive concept's novelty lies in its adaptation for specific, narrow markets or unique operational environments, which is not obvious from the original patent. The inventive step is the integration of weather data, secure authentication, and battery-powered backup systems to ensure the system's functionality in extreme environments.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include adapting the system for use in other extreme environments, such as high-altitude or underwater situations. Variations could include using different types of sensors or data sources to monitor CGM data, or integrating the system with other medical devices or wearables.

Potential Commercial Applications and Market

The inventive concept has commercial potential in the medical device industry, particularly in the areas of diabetes management and extreme environment medical care. The target market includes users with diabetes who require specialized care in extreme environments, as well as medical professionals and organizations providing care in these situations.
