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 invention discloses a nursing method and system based on a hierarchical monitoring mode, and relates to the technical field of monitoring nursing, and the method comprises the following steps: firstly, according to a preset detection period, carrying out the regular detection of the skin microcirculation perfusion state of a severely burnt patient, and evaluating the tissue perfusion and wound recovery conditions; by monitoring skin microcirculation changes in real time and combining a deep learning model, the scheme accurately captures early characteristics of blood hypercoagulability trend, such as microcirculation shear stress and pulsation strength changes, generates blood flow indexes, compares the blood flow indexes with reference thresholds, early recognizes the hypercoagulability state and timely intervenes; the risks of local necrosis, infection, septicemia and the like are reduced. Based on intelligent division, patients are divided into blood rheological balance and blood hypercoagulability trend, the detection frequency is dynamically adjusted, nursing resource allocation is optimized, personalized nursing is achieved, and prognosis and management quality of the patients are effectively improved.

The invention provides a tumor nursing method combined with traditional medicine, which comprises the following steps: collecting physiological data such as meridian conductance, acupoint temperature and qi and blood running rate of a patient through a multi-modal sensor, and after multi-dimensional preprocessing, inputting a dynamic harmonic algorithm to generate a personalized nursing parameter set, including acupuncture intensity, cupping positioning and scraping time sequence parameters. And the intelligent acupuncture device and the negative pressure cupping device execute corresponding operations according to the information. Meanwhile, skin microcirculation indexes and local temperature distribution are monitored in real time, body surface thermodynamic characteristics are obtained through an infrared thermal imager, and when monitoring data exceed a threshold value, an adjustment algorithm is fed back to dynamically correct a nursing parameter set. And finally, generating a nursing scheme, and outputting comprehensive nursing suggestions of traditional Chinese medicine constitution classification and prognosis evaluation reports. The nursing effect can be improved, the risk is reduced, and patient rehabilitation is promoted.

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.
