A sensor inserter for a physiological characteristic sensor includes a housing that defines a track system that extends from a bottom of the housing toward a top of the housing. The sensor inserter includes a striker assembly movable relative to the housing between a first state, a second, cocked state and a third, disposal state. The striker assembly is movable from the second, cocked state to the third, disposal state to couple the physiological characteristic sensor to an anatomy. The striker assembly includes a lock beam that engages with the track system as the striker assembly moves between the first state, the second, cocked state and the third, disposal state. In the third, disposal state the lock beam inhibits movement of the striker assembly from the third, disposal state to the first state.

The slats are configured to be displaced in a direction normal to the plane of the sheet and held in position when the edge of the sheet is pressed over the anatomical feature, so as to indicate a dimension of the feature.

Various embodiments enable calibrating a non-invasive blood pressure measurement device by determining multiple parameters defining a stress-strain relationship of an artery of a patient. The device may obtain output signals from a blood pressure sensor at two or more measurement elevations. The obtained measurement signals may be filtered into AC and quasi-DC components, and results fit to exponential functions to calculate an arterial time constant and a veinous time constant related to vein draining/filling rates. The arterial and veinous time constants may be used to calculate an infinity ratio. The infinity ratio and the obtained sensor output may be used to calculate values for multiple parameters defining a stress-strain relationship of a measured artery. Once defined, this stress-strain relationship may be stored and applied to future sensor output signals (e.g., blood pressure measuring sessions) to infer patient blood pressure.

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.
