The invention relates to the technical field of abnormal body temperature prediction, in particular to a newborn abnormal body temperature prediction method and device and a storage medium. The method comprises the following steps: collecting the body temperature and physiological signals of a newborn in real time, and carrying out preprocessing; based on fast Fourier transform, time sequence features reflecting body temperature changes in the body temperature and physiological signals are extracted, feature vectors are generated, the body temperature and physiological signals are processed through phase coupling analysis and a frequency domain mask inhibition mechanism, and a low-frequency noise interference interval caused by neonatal breathing irregularity and skin conduction disturbance is dynamically recognized; on the basis of the feature vectors, the body temperature abnormal risk probability is predicted in real time through the long-short-term memory network, the gating weight of the long-short-term memory network is dynamically regulated and controlled through two factors of the body temperature change rate and the physiological state label, and a feature fusion mechanism is optimized. According to the invention, through multi-modal physiological signal fusion and a dynamic feature weighting mechanism, the accuracy and real-time performance of newborn body temperature anomaly prediction are significantly improved.

This utility model discloses an emergency alarm device for cardiovascular postoperative care in the field of medical device technology. It includes a hospital bed and a positioning pillow. The positioning pillow is located at one end of the hospital bed, and a fixed frame is located at the other end. A sliding groove is embedded in the bottom of the fixed frame, and a slider is located inside the groove. An electric telescopic rod is located at the bottom of the slider. A thermal imager and an infrared thermometer are located at the bottom of the mounting plate. An alarm is located at the top of the fixed frame, and the alarm and infrared thermometer are electrically connected. Through the positioning pillow, fixed frame, sliding groove, slider, electric telescopic rod, mounting plate, thermal imager, infrared thermometer, and alarm, automatic measurement of the patient's body temperature is achieved. The slider slides inside the groove, thereby moving the thermal imager to confirm the patient's position. The infrared thermometer can then detect the patient's body temperature. When an abnormal body temperature is detected, the alarm is activated via the control center.

The invention discloses a non-intrusive sleep behavior monitoring system based on infrared machine vision, which relates to the field of sleep behavior monitoring, and comprises an infrared thermal imaging acquisition module for acquiring a thermal imaging image sequence of a monitored person in a sleep process; the data processing module performs preprocessing and body part segmentation on the thermal imaging image sequence; the sleep behavior recognition module calculates the quilt coverage rate index and the temperature change rate of each part based on the segmentation result, and recognizes the quilt opening and closing behaviors and the corresponding critical temperature in combination with the activity index; the abnormal body temperature monitoring module establishes a personalized temperature distribution base line of the monitored person and judges whether body temperature deviation caused by abnormal coverage states exists or not; and the output and control module outputs a monitoring result, triggers linkage of external equipment according to an abnormal result, and obtains body surface temperature distribution information of a monitored person in a non-contact manner through an infrared thermal imaging technology, so that high-precision and non-intrusive sleep behavior monitoring and abnormal exposure early warning are realized.
