Devices and methods for determining item-specific information for single or multiple items on one or multiple substrates are described. The method includes generating multiple sensor multiple dimensions array (MSMDA) data from multiple sensors, where each of the multiple sensors capture sensor data for one or more items in relation to a substrate. For each item, the method includes determining relationships between the multiple sensors based on characteristics of the MSMDA data, determining a location of the item on the substrate based on at least the determined relationships between the multiple sensors, determining an angular orientation of the item on the substrate based on at least the determined relationships between the multiple sensors, and determining a body position of the subject on the substrate based at least the determined relationships between the multiple sensors, the location of the subject, and the angular orientation of the item.

A bed comprises substrate support members, each including a load bearing and a base configured to provide contact with a floor. The load bearing member is configured to move vertically relative to the base, while the base and the load bearing member are configured to fit together to maintain lateral alignment of the base and the load bearing member. A load sensor is positioned between the base and the load bearing member, the load bearing member configured to transmit a load from the substrate to the load sensor. A printed circuit board is in communication with the load sensor. A controller is in communication with the printed circuit board of each substrate support member and is configured to receive and process data output by the printed circuit boards.

The present disclosure provides methods of identifying a patient in need of pressure ulcer treatment and treating the patient with clinical intervention selected based on sub-epidermal moisture values. The present disclosure also provides methods of stratifying groups of patients based on pressure ulcer risks and methods of reducing incidence of pressure ulcers in a care facility.

One variation of a method for detecting inflammation in a foot includes: accessing a first temperature measured through a left temperature sensor and a second temperature measured through a right temperature sensor at approximately a first time, the left temperature sensor arranged in a left sock and the right temperature sensor arranged in a right sock worn on the user's feet; calculating a baseline difference between the first and second temperatures based on confirmation of absence of inflammation in the user's left and right feet at the first time; accessing a third temperature measured through the left temperature sensor and a fourth temperature measured through the right temperature sensor at approximately a second time; and in response to a second temperature differencebetween the third and fourth temperaturesdiffering from the baseline difference by more than a threshold difference, issuing an alarm through the user interface.

The present disclosure provides apparatuses and computer readable media for measuring sub-epidermal moisture in patients to determine damaged tissue for clinical intervention. The present disclosure also provides methods for determining damaged tissue.

A system and a method are described for preventing pressure ulcers in a medical care environment by monitoring adherence to a pressure ulcer prevention protocol. The method also includes identifying a first subset of pixels from the plurality of potential locations as representing a bed and/or a seating platform. The method also includes identifying a second subset of pixels within the field of view of the camera as representing an object (e.g., a subject, such as a patient, medical personnel; bed; chair; patient tray; medical equipment; etc.) proximal to the bed and/or seating platform. The method also includes determining an orientation of the object with respect to the bed and/or seating platform, and determining changes in the orientation and/or position of the object over a period of time. In implementations, the method further includes issuing an electronic communication alert based upon the determined orientation and/or position of the object over the period of time.

A system for monitoring medical conditions including pressure ulcers, pressure-induced ischemia and related medical conditions comprises at least one sensor adapted to detect one or more patient characteristic including at least position, orientation, temperature, acceleration, moisture, resistance, stress, heart rate, respiration rate, and blood oxygenation, a host for processing the data received from the sensors together with historical patient data to develop an assessment of patient condition and suggested course of treatment. In some embodiments, the system can further include a support surface having one or more sensors incorporated therein either in addition to sensors affixed to the patient or as an alternative thereof. The sensor can include bi-axial or tri-axial accelerometers, as well as resistive, inductive, capactive, magnetic and other sensing devices, depending on whether the sensor is located on the patient or the support surface, and for what purpose. Compensation for errors introduced because of chest angle or slope can be automatically performed.

Introduced here are pressure-mitigation systems able to mitigate the pressure applied to a human body by the surface of an object. A system can include a pressure-mitigation device with chambers whose pressure can be varied by a controller that regulates the flow of fluid produced by a pump. The controller may be deployed as part of a closed loop system that autonomously infers information related to the health of a patient based on data related to the pressure of these chambers. For example, the data may be examined to determine whether the values indicate the patient is properly situated. A notification may be presented responsive to determining that the patient is not situated on the pressure-mitigation device, the patient has been improperly situated on the pressure-mitigation device for a certain amount of time, etc. Thus, real-time feedback may be provided to those responsible for monitoring the patient.

Embodiments of tissue monitoring in combination with negative pressure wound therapy systems and methods are disclosed. In some embodiments, a monitoring and therapy system comprises collecting video images of a tissue site and amplifying said video images via Eulerian Video Magnification. Depending upon the changes detected via Eulerian Video magnification, negative pressure wound therapy may be delivered to the tissue site, stopped, or altered in some manner.
