The invention discloses a pressure injury risk early warning method and equipment, and relates to the technical field of medical monitoring instruments. The pressure sensor array layout can be self-adaptive to the body shape of a patient, a key osseous process part is covered, no monitoring dead angle is ensured, a temperature compensation mechanism is built in, environmental interference is reduced, the measurement precision is improved, an abnormal pressure threshold value can be dynamically set based on individual medical record data, data verification is performed before early warning is triggered, false alarm is avoided, and the array structure is light, thin and flexible. The mask is comfortable to fit skin, supports long-term wearing and is easy to disinfect and maintain; environment temperature and humidity parameters and pressure data are subjected to fusion analysis, the influence of a high-temperature and high-humidity environment on skin microcirculation can be recognized, the risk of pressure sores can be evaluated in an auxiliary mode, a calibration algorithm is built in a sensor, environment fluctuation interference is reduced, and data reliability is ensured; and the early warning unit comprises sound-light alarm equipment which supports a multi-stage alarm mode and is used for triggering an early warning signal and pushing information when the risk index exceeds a threshold value, so that the early warning timeliness is ensured and the false alarm risk is reduced.

The application discloses a skin microcirculation imaging system and method based on functional ultrasound, and belongs to the technical field of medical monitoring. The system comprises an inertial measurement unit, a state decision and power gating module, and an ultrasound imaging link. The inertial measurement unit continuously monitors the motion state of the system; the state decision and power gating module judges whether the system enters a continuous stationary state according to a dynamic motion intensity sequence, and accordingly wakes up or puts the ultrasound imaging link to sleep; the ultrasound imaging link collects original ultrasound echo data after being woken up. During data collection, if it is monitored that the dynamic motion intensity exceeds a preset fuse threshold, the state decision and power gating module immediately suspends data collection and puts the ultrasound imaging link to sleep. The application solves the contradiction between the power consumption of a wearable device and the effectiveness of data, and realizes high-robustness, high-diagnostic-value microcirculation monitoring under super-long endurance.
