Compliance with Head-of-Bed protocols can also be performed based on actual patient position instead of being inferred from bed elevation angle. The sensor can include bi-axial or tri-axial accelerometers, as well as resistive, inductive, capacitive, magnetic and other sensing devices, depending on whether the sensor is located on the patient or the support surface, and for what purpose.

A system for predicting an occurrence of a foot ulcer includes a mat configured to be stood upon by a human subject, a plurality of sensor arrays disposed on or in said mat and arranged in adjacent proximity to one another. Each sensor includes an oxygenation probe, itself including a first light source and a light detector, and a secondary probe operable to utilize the light detector of the oxygenation probe and itself including a plurality of light sources exclusive of the first light source. The plurality of light sources of the secondary probe are arranged in a pattern around the oxygenation probe. The oxygenation probe is located at the approximate geometric center of the pattern. The system further includes a control module in signal communication with the light detector, and configured to independently control emission of light from the first light source of the oxygenation probe and the plurality of light sources of the secondary probe.

A caregiver assistance system is disclosed for helping caregivers manage the care of existing bed sores and/or reduce the risk of a patient developing bed sores. The system may also help the caregiver to perform rounding tasks and/or to reduce the likelihood of patient falls. The system comprises a server application in communication with the patient's bed and one or more mobile electronic devices (e.g. smart phones). The mobile devices receive individual assessments of a plurality of bed sore risk factors and forward them to the server. The server generates bed sore risk scores from the answers and forward them to an EMR server. The server may also determine one or more risk reduction steps, display them on the mobile electronic device, and/or forward them to the patients' beds for implementation thereon. Additional bed sore information may be captured and sent to the EMR.

Techniques for patient pressure injury prevention (PPIP) include receiving, from a plurality of pressure sensors configured to be disposed in a spatial arrangement in contact with a patient, samples that indicate pressure measurements by the plurality of sensors at each of a plurality of different times. At each of the plurality of different times an angular orientation of the pressure is determined based on the samples. A change in the angular orientation of the pressure is determined at each successive time of the plurality of different times. A value of a patient movement parameter is determined based on the change in angular orientation of the pressure. A pressure injury category for the patient based on the value of the patient movement parameter is presented on a display device for a caregiver. Treatment of the patient by the caregiver is based on the pressure injury category.

A long-term care support device includes: a sensor data acquisition device that acquires biological information of a user that was measured by a sensor; a sleep stage detection device that detects a sleep stage of the user based on the acquired biological information; a timing determination device that determines that it is time to change the position of the user if the sleep stage of the user is the deep sleep stage; and a notification device that, if the timing determination device determined that it is time to change the position of the user, gives a notification to such effect

Example apparatuses, systems, and methods for detecting a muscle tissue ischemia event are provided. An example apparatus may include an electromyography (EMG) sensor applied to a patient to detect electrical activity in the muscle tissue. The apparatus may also include processing circuitry in communication with the EMG sensor and configured to receive EMG signals from the EMG sensor and detect characteristics within the EMG signals indicating oxygen depletion within the muscle tissue of the patient. The characteristics may include a signal power level of the EMG signals increasing by at least a threshold value at a select frequency or with respect to a select band of frequencies. The processing circuitry may be further configured to trigger an output, in response to detecting the characteristics, indicating that the oxygen depletion in the muscle tissue is indicative of an ischemia event.

A patient immersion sensor includes a radio detection and ranging (RADAR) apparatus to determine a time of flight (TOF) of a RADAR pulse and a reflected signal that is reflected by a patient or by a portion of a patient support surface supporting the patient. The TOF is indicative of an immersion depth or a distance toward bottoming out of a patient supported on the patient support surface, such as a mattress or a pad. The RADAR apparatus emits pulses of very short duration so as to be able to detect objects, such as a patient or a portion of a mattress or pad, at very close distances. The RADAR apparatus may use time-of-flight (TOF) between transmission of the pulse and receipt of a reflected signal to determine a distance toward bottoming out by the patient, thereby to determine if the patient is properly immersed into the patient support surface. Adjustments to inflation or deflation of one or more bladders are made to achieve a desired immersion amount within a tolerance range between upper and lower TOF thresholds.
