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

This inventive concept adapts the original blood flow monitoring apparatus for specific, high-demand environments, including high-altitude, disaster relief, high-security, extreme weather, and remote, off-grid locations.

Background and Problem Solved

The original patent addresses the need for measuring blood flow in the foot, particularly for diabetic patients. However, the original design may not be suitable for operation in unique environments with extreme conditions. This inventive concept solves the problem of adapting the blood flow monitoring apparatus for these specialized environments, ensuring accurate and reliable measurements in diverse settings.

Detailed Description of the Inventive Concept

The new inventive concept comprises a range of specialized systems and methods for monitoring blood flow in the foot, each tailored to a specific environment. For high-altitude environments, the system includes a portable platform and PPG sets configured to operate at low atmospheric pressures. In disaster relief situations, the method involves analyzing PPG signals obtained from a foot in a disaster relief setting and generating an alert based on the analysis. For high-security environments, the apparatus features a tamper-evident platform and PPG sets that encrypt the PPG signals. In extreme weather conditions, the system includes a waterproof platform and PPG sets configured to operate in wet environments. Finally, for remote, off-grid locations, the method involves analyzing PPG signals obtained from a foot using a portable, solar-powered PPG apparatus and transmitting the analysis results via satellite communication.

Novelty and Inventive Step

The new inventive concept introduces novel adaptations of the original blood flow monitoring apparatus, including specialized components and configurations that enable operation in unique environments. The inventive step lies in the tailored design of each system and method to address the specific challenges of its intended environment, ensuring reliable and accurate blood flow measurements in diverse settings.

Alternative Embodiments and Variations
