This invention relates to the field of medical monitoring technology and discloses a joint intelligent assessment system for skin flap color and temperature. The system includes a multimodal data acquisition module for the flap, a surface attribute analysis module for the flap, a deep pathological inference module, and a dynamic survival status prediction module. It generates a data package with a unified spatiotemporal reference by simultaneously acquiring and fusing color texture images and infrared thermal imaging data. The system quantifies and analyzes the boundaries and parameters of abnormal color and temperature regions from the fused data, then calculates the spatial overlap and correlation between abnormal color and temperature regions, and generates inference vectors representing deep blood supply and metabolic status based on rules. A state evolution model is constructed by combining historical vector data to achieve dynamic prediction of the flap's survival status. This system realizes the objective and synchronized analysis of multimodal information on flap appearance and inference of deep pathological correlations, improving the accuracy and early warning capabilities of postoperative monitoring.

Supporting various services related to digital legacy that smoothly substitute the procedures for handling digital legacy without waiting for requests from the bereaved family, and recover and delete digital legacy in accordance with the will of the deceased. 【Solution means】 The system is a digital legacy management system in which a first data terminal 3 operated by the contractor himself / herself communicates with a server device 1 that substitutes the procedures for handling the legacy in accordance with the management contract for the digital legacy requested from the terminal. The server device 1 requests the first data terminal 3 to confirm the survival of the contractor himself / herself as a survival confirmation request. The CPU 1-2 determines the survival status of the contractor based on the response result from the first data terminal 3, and automatically deletes the digital legacy of the deceased registered in the contract servers 2-1 to 2-N when the survival status of the contractor cannot be confirmed.
