Abstract: The present disclosure provides apparatuses and methods for measurement of the biocapacitance of tissue. The apparatus comprises a sensor comprising two electrodes, a movable element coupled to the sensor, and a switch disposed between the movable element and a fixed element, wherein the switch electrically closes when a gap between the movable element and the fixed element is less than or equal to a pre-determined value. The device makes a measurement of the biocapacitance between the two electrodes when the switch closes.

Abstract: The construction of a medical device having a disposable element is disclosed. Detachable elements comprising a body having a retention feature, an electrical contactor, and sensors are also disclosed.

Further disclosed are detachable elements comprising a body having an opening and a printed film comprising conductive elements, where the conductive elements comprise a sensor configured to be aligned with the opening to expose the sensor. Further disclosed are reusable components having matching retention features.

Abstract: The present disclosure provides methods and apparatus for evaluating tissue structure in damaged or healing tissue. The present disclosure also provides methods of identifying a patient at the onset of risk of pressure ulcer or at risk of the onset of pressure ulcer, and treating the patient with anatomy-specific clinical intervention selected based on a number of sonographic characteristics. The present disclosure also provides methods of stratifying groups of patients based on risk of wound development and methods of reducing incidence of tissue damage in a care facility. The present disclosure also provides methods to analyze trends of sonographic characteristics to detect tissue damage before it is visible, and methods to compare bisymmetric sonographic characteristics to identify damaged tissue.

Abstract: The present disclosure provides methods for evaluating tissue damage and the use of spatial variation in Sub-Epidermal Moisture (SEM) values to determine damaged tissue for clinical intervention. The present disclosure provides methods of identifying deep and early-stage pressure-induced injuries or ulcers (PI/PU). The present disclosure provides algorithm for computing SEM delta values which inform clinical decision-making for developing intact skin PI/PUs including suspected deep tissue injury (sDTI) and Stage I PI/PUs.

Abstract: Methods and apparatus for detection of tissue damage in patients using a medical device for an extended period of time are disclosed.

Abstract: The present disclosure provides for, and includes, a method of detecting tissue damage before it is visible on a patient's skin, comprising: measuring a plurality of sub-epidermal moisture (SEM) values at a single location at incremental times, calculating a slope between the latest SEM value and the immediately prior SEM value, comparing this slope to a threshold value, and determining that there is tissue damage if the slope exceeds the threshold value.

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.
