Benefits of technology

The present invention is a wireless, biocompatible RF powered sensing system that can monitor skin or wound development in real-time using a smart SEM imager. This system allows for early detection of ulcer formation or inflammatory pressure, which would have been otherwise undetected for an extended period, increasing the risk of infection and higher stage ulcer development. The invention allows for better management of individual patients by maintaining a database of data collected from patients with chronic wounds, diabetic foot ulcers, pressure ulcers, or post-operative wounds. This approach integrates signal content with the patient's activity level, position, and standardized assessments of symptoms. This technology can have broad applications in wound management and skin diseases or treatments, providing early detection and timely interventions to improve patient outcomes and prevent complications.

Problems solved by technology

Patients' skin integrity has long been an issue of concern for nurses and in nursing homes.
Meanwhile, pressure ulcers remain a major health problem particularly for hospitalized older adults.
When age is considered along with other risk factors, the incidence of pressure ulcers is significantly increased.
Pressure ulcers additionally have been associated with an increased risk of death one year after hospital discharge.

embodiment 1

[0077]2. The apparatus of embodiment 1, further comprising: an annular spacer adjacent and underneath the conformal pressure pad; wherein the annular spacer comprises a central opening configured to allow the conformal pressure pad to deflect freely into the central opening.

[0078]3. The apparatus of embodiment 1, further comprising: an array of bipolar RF sensors spaced across the flexible substrate; wherein each of the sensors is independently coupled to the interface electronics to independently interrogate the patient's skin.

embodiment 3

[0079]4. The apparatus of wherein each of the sensors is configured to measure an equivalent sub-epidermal capacitance of a target region of skin; said sub-epidermal capacitance corresponding to the moisture content of the target region of skin.

embodiment 4

[0080]5. The apparatus of wherein the array of sensors comprises a first sensor having a first contact area and a second sensor having a second contact area larger than the first sensor; wherein the first and second sensors interrogate the skin at different depths.

[0081]6. The apparatus of embodiment 4: wherein the substrate comprises a substrate assembly comprising a substrate layer; and wherein the sensor comprises a sensing pad having a first electrode embedded on a first side of the substrate and a second electrode embedded on a second side of the substrate.

Abstract

A handheld, conforming capacitive sensing apparatus configured to measure Sub-Epidermal Moisture (SEM) as a mean to detect and monitor the formation of pressure ulcers. The device incorporates an array of electrodes which are excited to measure and scan SEM in a programmable and multiplexed manner by a battery-less RF-powered chip. The scanning operation is initiated by an interrogator which excites a coil embedded in the apparatus and provides the needed energy burst to support the scanning / reading operation. Each electrode measures the equivalent sub-epidermal capacitance corresponding and representing the moisture content.
