Device for Diagnosing Circulation Disorders and Inflammation in the Feet of Diabetes Patients

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention is a diagnostic device integrated into shoe insoles or foot garments, specifically designed for diabetes patients. The device features an array of embedded pressure and temperature sensors, a movement sensor or tilt switch, and a data processing and transmission system. Collectively, these components allow continuous monitoring for circulation disorders and early signs of foot inflammation (such as ulcers) by tracking temperature and pressure at key areas across both feet, with real-time alerts sent to patients and/or healthcare providers.

Use CasesContent extracted from patent full text and abstract with AI.

• Daily monitoring of foot health in diabetic patients to prevent complications such as ulcers and tissue necrosis.
• Remote health supervision by clinicians through data collected from patients’ insoles.
• Self-management for diabetic patients via connected alerts on smartphones or tablets.
• Early detection and warning system for diabetic foot syndrome, prompting users to relieve pressure or seek medical attention.
• Integration into smart home healthcare ecosystems for high-risk individuals.
• Assisting podiatrists in tracking patients’ compliance with recommended foot-care regimens by analyzing usage patterns and alert responses.

BenefitsContent extracted from patent full text and abstract with AI.

• Provides continuous, automated monitoring and early detection of potential foot complications for people with diabetes.
• Enables personalized warnings and actionable recommendations to prevent injuries before they become critical.
• Allows for remote and timely medical intervention, potentially reducing hospitalization and costly treatments such as amputation.
• Improves patient safety and quality of life by helping maintain healthy foot circulation and integrity.
• Minimizes the subjective aspect of foot inspection for individuals with neuropathy and diminished sensory feedback.
• Data can be shared with healthcare professionals for comprehensive health management and tailored medical decisions.

Patent Abstract

The invention relates to devices for diagnosing circulatory disorders and developing inflammations in the feet of patients with diabetes with soles for footwear. These are characterized in particular by simple implementation. For this purpose, these soles for or of footwear have at least one signal device (8) and/or at least one external device connectable to the data processing systems and having a data processing device. The soles each comprise per sole - pressure sensors and first temperature sensors arranged and embedded at specific locations for determining the temperature-dependent blood circulation of the area of the respective foot associated with the location, - at least one second temperature sensor (4) for determining the ambient temperatures of the foot in the footwear, - at least either a motion sensor (5) or a tilt switch, - a data processing system (6) interconnected with the pressure sensors, the first temperature sensors, the second temperature sensor (4) and either the motion sensor (5) or the tilt switch, in connection with a transmitter/receiver as a data transmission device, and - an electrical energy source (8) in connection with at least the data processing system (6).
