Method for pain quantification based on a three-dimensional human body model

Abstract

The application provides a pain quantitative evaluation method based on a three-dimensional human body model. The three-dimensional human body model is displayed on a display device of a computing device and is composed of a plurality of modules corresponding to respective tissues and organs of a human body. When a subject performs pain calibration, the subject performs painting on a module corresponding to a tissue or organ where the subject feels pain. The color of the painting represents the pain degree, and the three-dimensional space volume of the painting represents a pain area.

Description

Technical Field

[0001] This application relates to quantitative pain assessment techniques, and more particularly to a method for quantitative pain assessment based on a three-dimensional human body model. Background Technology

[0002] Pain is one of the most common clinical symptoms and a complex physiological and psychological activity. The International Association for the Study of Pain defines pain as: an unpleasant sensory and emotional experience associated with existing or potential tissue damage. Currently, pain has become the fifth vital sign after body temperature, pulse, respiration, and blood pressure, and is receiving increasing attention from the international community.

[0003] CN105718730A discloses a "method for quantifying pain assessment of subjects and a system for implementing the method", which can depict the pain sensation of subjects on a three-dimensional human body model, and represent the range and degree of pain by the size and color of the painted area. In addition, the depth of pain can be depicted by selecting an end face.

[0004] While the descriptions and representations of pain intensity in the aforementioned patents are relatively intuitive, the corresponding tissues of the pain areas are not clearly defined, which is not conducive to doctors and patients, especially patients, intuitively understanding the location of the pain. Furthermore, the correlation between the pain area and organs cannot be intuitively demonstrated. Summary of the Invention

[0005] In view of the above problems, this application aims to propose a method for quantitative assessment of pain based on a three-dimensional human body model.

[0006] The present application discloses a method for quantitative pain assessment based on a three-dimensional human body model, wherein the three-dimensional human body model is displayed on a display device of a computing device and consists of multiple modules corresponding to various tissues and organs of the human body; when the subject performs pain calibration, he or she draws on the module corresponding to the tissue or organ in which he or she feels pain, and the color of the drawing represents the degree of pain, and the three-dimensional spatial volume of the drawing represents the pain area.

[0007] This application also proposes a pain quantitative assessment device based on a three-dimensional human body model, wherein the three-dimensional human body model is a digital model running in a computing device and is displayed on the display device of the computing device; the three-dimensional human body model consists of multiple modules corresponding to various tissues and organs of the human body; when the subject performs pain calibration, he or she draws on the module corresponding to the tissue or organ in which he or she feels pain, and the color of the drawing represents the degree of pain, and the three-dimensional spatial volume of the drawing represents the pain area.

[0008] Preferably, the three-dimensional human body model can mark the location of pain on any cross-section.

[0009] Preferably, the three-dimensional human body model can mark the location of pain on the corresponding plane in any sagittal or coronal plane.

[0010] Preferably, after a certain module of the three-dimensional human body model is marked with pain, the name of the corresponding human tissue or organ is displayed. Detailed Implementation

[0011] Based on CN105718730A, this application modularizes the human body model therein.

[0012] CN105718730A is merely a rotatable 3D human body model. This application upgrades the human body model to a digital human body model, meaning that individual human tissues and organs can be accurately labeled.

[0013] CN105718730A only shows superficial pain, or can only mark deep pain in four cross-sections: chest, waist, thigh, and calf. This localization is coarse. This application uses a digital human body model, which can mark the location of pain in any cross-section (meaning an infinite number and infinitely subdivided cross-sections). Compared with CN105718730A, it greatly supplements the various human body layers, especially adding pain annotations for important locations such as the head, neck, pelvis, and even feet, forming a complete tissue layer annotation of the human body.

[0014] This application demonstrates the ability to accurately and clearly mark the location of pain not only in the transverse (horizontal) plane, but also at any level in the sagittal and coronal planes. It truly achieves precise localization within the human body, allowing for marking of the skin, fascia, muscles, bones, and even the interior of bones, with significantly clearer layer distinctions.

[0015] Another advantage of this application is that it can clearly label various organs and tissues, such as the heart, liver, spleen, lungs, kidneys, intestines, brain, male and female reproductive systems, thyroid gland, and sensory organs. This achieves an accuracy and clinical guidance significance that CN105718730A cannot reach. Specifically, when a user labels a specific depth on a cross-section, the organ or tissue at that location will be clearly marked, allowing the user to clearly see whether the label indicates the liver, small intestine, or pericardium.

[0016] The accurate annotations described above are particularly effective in representing the musculoskeletal system, which is the most pain-prone area in the human body. Compared to CN105718730A, which only shows a rough outline of the human body, this application enhances all aspects of the human musculoskeletal system, displaying all 206 bones and over 600 muscles. When a user marks the location of a musculoskeletal structure, the name of that muscle or bone will be displayed, thus providing greater clinical reference value.

[0017] Unless otherwise defined, all technical and / or scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this invention relates. The materials, methods, and embodiments mentioned in this application are illustrative only and not restrictive.

[0018] Although the present invention has been described in conjunction with specific embodiments, those skilled in the art can make appropriate substitutions, modifications and changes within the inventive spirit of this application, and such substitutions, modifications and changes still fall within the protection scope of this application.
