Device for Diagnosing Blood Circulation Disorders and Inflammation in Feet of Patients with Diabetes or with Peripheral or Central Neurodamage and the Optical Documentation of Foot Injuries

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

This invention describes a diagnostic device designed to detect blood circulation disorders and inflammation in the feet of patients suffering from diabetes or nerve damage, using a platform equipped with a matrix of temperature sensors and imaging components. The device enables simultaneous thermal and optical documentation of the feet, helping to identify early signs of foot injury, ulcers, or complications by associating visual images with corresponding temperature profiles. The system can store, process, and transmit data to both patients and healthcare providers, thereby supporting timely intervention and continuous monitoring.

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

• Routine at-home self-monitoring of feet by diabetic patients to detect early signs of ulcers or injuries.
• Use in clinics or hospitals for objective documentation and comparison of foot health over time for patients with neuropathy or circulatory disorders.
• Integration with telemedicine services, allowing remote assessment of foot conditions by healthcare professionals.
• Application in rehabilitation centers for monitoring the progress of foot recovery or management of chronic foot diseases.
• Potential use in elder care facilities for non-invasive, regular monitoring of residents at risk of foot complications.

BenefitsContent extracted from patent full text and abstract with AI.

• Enables early detection and prevention of serious foot complications like ulcers or infections in at-risk patient populations.
• Allows objective, repeatable documentation of both temperature patterns and visual condition of the foot for clinical records and patient self-assessment.
• Supports personalized medical intervention by comparing current and historical data, enhancing disease management.
• Facilitates remote monitoring and timely alerts to patients and physicians, reducing the need for frequent in-person visits.
• Improves patient adherence to monitoring routines due to ease of use and immediate feedback.
• Helps reduce healthcare costs by preventing advanced complications that require intensive treatment or hospitalization.

Patent Abstract

The invention relates to devices for diagnosing circulatory disorders and developing inflammations in the feet of patients with diabetes or with peripheral or central nerve damage, for example polyneuropathy or stroke, as well as for optical documentation of foot injuries. The devices are characterized in particular by the fact that at least one foot of the patient can be easily identified and subsequently documented. For this purpose, a platform for at least one foot has temperature sensors arranged in a matrix. The side of the platform opposite to the side with the surface for the foot has at least one lighting unit and image sensors for the foot. At least one area of the platform consists of a material that is transparent to the light rays of the lighting unit and to the light rays reflected from the foot. The lighting unit, the image sensors and the temperature sensors are furthermore connected to a data processing system, wherein this is a data processing system that assigns temperatures to the image of the sole of the foot.
