Pain evaluation method, system, equipment and storage medium

Abstract

The invention provides a pain evaluation method, system, equipment and a storage medium. The method comprises the steps: acquiring physical sign parameters, face expression videos and limb action videos of users corresponding to different pain states; carrying out training based on a depth neural network by using the face expression videos and the limb action videos, so as to obtain a first pain identification model and a second pain identification model; calculating a physiological pain score by using physical sign parameters of a user to be tested, and correspondingly inputting a face expression video and limb actions of the user to be tested to the first pain identification model and the second pain identification model, so as to obtain a face pain score and a limb pain score; and calculating a weight sum of various pain scores in accordance with a preset weight coefficient, thereby obtaining an evaluation pain value of the user to be tested. The method is applicable to new-born infants or people without language performance, errors caused by artificial subjective pain degree judgment can be avoided, the efficiency and accuracy of pain evaluation are improved, and the method has the advantages of wide applicable range, high sensitivity and simplicity in evaluation.

Description

technical field [0001] The present invention relates to the related fields of machine learning and biomedicine, in particular to a pain assessment method, system, device and storage medium applicable to newborn infants. Background technique [0002] Pain is a social communication tendency of human evolution. As a special sensory experience related to injury, it can convey the discomfort caused by various harmful stimuli. Pain is of great significance and value to the survival of individuals. In 1976, the International Association for the Study of Pain (IASP) defined pain as "an unpleasant subjective sensory and emotional experience associated with tissue damage or potential damage". In 1995, the American Pain Society listed pain as the fifth vital sign and emphasized the importance of systematic evaluation and routine recording of pain. [0003] For newborn babies, patients who have lost the ability to express their voice, etc., who cannot express their pain feelings, espec...
