Quantitative evaluation method for pain of subject and system for implementing method

Abstract

The invention relates to a quantitative evaluation method for the pain of a subject. The method comprises the steps of painting painful positions in predetermined colors on a preset three-dimensional human model to represent pain types and pain areas, wherein the predetermined colors are various different colors, each color is corresponding to one pain type and the number of pixels at the painted pain areas represents the pain degree; and showing a cross section drawing at a selected position of the three-dimensional human model and further marking the pain positions of the subject on the cross section drawing to reflect the pain depth of the subject.

Description

technical field [0001] The present invention relates to quantitative evaluation of pain, in particular to a method for quantitative evaluation of pain on a subject and a system for implementing the method. Background technique [0002] Pain is the most common clinical symptom and a complex physiological and psychological activity. The International Pain Society defines pain as: an unpleasant sensory and emotional experience associated with existing or potential tissue damage. At present, pain has become the fifth vital sign following the four vital signs of body temperature, pulse, respiration, and blood pressure, and has been increasingly valued by the international community. [0003] Compared with the first four signs, pain is very special: there is still no objective biological instrument to detect pain and describe the degree of pain. In fact, pain is a subjective experience, so it is difficult to have objective tools to measure pain levels. With the deepening of sci...

AI Technical Summary

Problems solved by technology

[0005] Pain drawings provide surgeons with a tool to understand the location and nature of pain in patients, but the current pain drawings have the following deficiencies: (1) The outline of the human body in pain drawings is a two-dimensional plane, while the human body is a three-dimensional structure, so based on Human pain drawings of flat models cannot accurately display accurate information highly correlated with the distribution area of ​​nerve root symptoms

Each nerve root has its main innervated sensory area, which is reflected in the three-dimensional structure of the human body. The pain drawings of the two-dimensional human body model affect the preparation and judgment of the pain site and the direction of the nerve root; (2) the pain-related depth information cannot be displayed; ( 3) The information on the pain chart is not integrated with the patient's past medical history, current imaging data, and doctor's physical examination information

These deficiencies all affect the surgeon's accurate judgment of the patient's condition
