This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,756.

Summary of the Inventive Concept

A wearable insulin infusion patch system that integrates advanced glucose sensing, real-time monitoring, and personalized insulin dosing, revolutionizing diabetes management.

Background and Problem Solved

The original Rotational Metering Pump for Insulin Patch patent addressed the need for a reliable and user-friendly insulin delivery system. However, it had limitations in terms of glucose level monitoring and real-time insulin dosing adjustments. The new inventive concept addresses these limitations by integrating advanced glucose sensing and real-time monitoring capabilities, enabling personalized insulin delivery and improving diabetes management.

Detailed Description of the Inventive Concept

The Next-Generation Wearable Insulin Infusion Patch System consists of a rotational metering pump, an integrated glucose sensor, and a microcontroller for real-time monitoring and adjusting insulin dosing based on glucose levels and user activity. The system can receive glucose level data from the integrated glucose sensor, analyze user activity data from an accelerometer, and adjust insulin dosing in real-time. The system can also be modular, with detachable glucose sensor and wireless communication modules, enabling seamless integration with remote devices. Furthermore, the system can incorporate neural network-based algorithms for predicting glucose levels and adjusting insulin dosing, providing a closed-loop insulin delivery system.

Novelty and Inventive Step

The new inventive concept introduces the integration of advanced glucose sensing, real-time monitoring, and personalized insulin dosing, which is not present in the original patent. The use of machine learning algorithms, modular design, and wireless communication capabilities further distinguish the new concept from the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the Next-Generation Wearable Insulin Infusion Patch System could include the use of different types of glucose sensors, such as enzymatic or optical sensors, or the incorporation of additional health monitoring features, such as heart rate or blood pressure monitoring. Variations could also include different materials or designs for the patch system, such as flexible or stretchable materials, to enhance user comfort and convenience.

Potential Commercial Applications and Market

The Next-Generation Wearable Insulin Infusion Patch System has significant commercial potential in the diabetes management market, with an estimated global value of over $10 billion by 2025. The system's advanced features and personalized insulin delivery capabilities position it to capture a significant share of this market, particularly among patients with type 1 and type 2 diabetes.
