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. 11,857,303.

Summary of the Inventive Concept

A novel system integrating a foot-mounted PPG device with AI-driven analytics, IoT-sourced data, and blockchain-based health records to provide early detection and personalized management of cardiovascular disease.

Background and Problem Solved

The original patent addressed the need for accurate blood flow measurement in the foot, particularly for diabetic patients. However, it did not provide a comprehensive solution for cardiovascular health monitoring. The new inventive concept addresses this limitation by combining the patented foot-mounted PPG device with advanced technologies to create a more powerful system.

Detailed Description of the Inventive Concept

The system consists of a foot-mounted PPG device, an AI-driven analytics module, an IoT communication module, and a blockchain-based health record system. The PPG device measures blood flow in the foot, while the AI-driven analytics module processes the data to identify early indicators of cardiovascular disease. The IoT communication module enables secure data transmission to a remote server, and the blockchain-based health record system ensures secure storage and sharing of patient data.

Novelty and Inventive Step

The new claims introduce the innovative combination of a foot-mounted PPG device with AI-driven analytics, IoT-sourced data, and blockchain-based health records, providing a synergistic solution for cardiovascular health monitoring. This integration is non-obvious and novel compared to the original patent.

Alternative Embodiments and Variations

Alternative embodiments may include using different types of sensors, such as ECG or pressure sensors, or integrating the system with other health monitoring devices. Variations may include using different AI algorithms or blockchain protocols.

Potential Commercial Applications and Market

The intelligent foot-mounted cardiovascular health monitoring system has significant commercial potential in the healthcare industry, particularly in the areas of preventive medicine, personalized health management, and telemedicine.
