Intelligent Network Multimedia Cardiopulmonary and Abdominal Exam System

System Overview
■   The system mainly consists of a chest examination simulator, an abdominal examination simulator, a computer, and an experimental platform. The computer is equipped with chest and abdominal examination teaching software, which is wirelessly connected to the simulator via USB or WIFI. There are two types of machines: teacher machines and student machines.
■   The software system is based on the new version of the "Diagnosis" textbook and the "Internal Medicine" textbook, realizing the interaction between intelligent simulation humans and computers, fully reflecting the skill training and assessment of "seeing, touching, tapping, and listening" in the chest and "seeing, hearing, touching, tapping" in the abdomen of diagnosis.
■   The software system contains rich multimedia content, including 3D simulation animations, 2D animations, live teaching videos, detailed text explanations, and case images. According to the textbook content, it integrates visual examination, palpation, percussion, auscultation, and theoretical teaching of various common disease signs in the respiratory system, circulatory system, and abdomen, vividly explaining the anatomical changes of pathological signs and the mechanism of auscultation sounds.
■   The teacher machine has two teaching modes: unified teaching and free learning. Under the unified teaching mode, all students can only learn synchronously with the teacher, while under the free learning mode, students can fully learn independently.
■   The software system has multiple categories of assessment content and can be used for self practice, self assessment, and joint control assessment. Equipped with an examination system, it can manage multiple exam papers, including independent topic selection and random system selection; The system has functions such as exporting test papers, saving test papers, viewing grades, printing, and automatic scoring by the system.

Chest examination simulator
■  The simulator human's pupils are displayed on a liquid crystal display, which can simulate dilated pupils, normal pupils, reduced pupils, and needle like pupils, and has the ability to reflect light.
■  Palpable bilateral carotid artery pulsation, with adjustable pulse frequency.
■  Heart sounds can be auscultated in the aortic valve area, pulmonary valve area, mitral valve area (apex), tricuspid valve area, and the second auscultation area of the aortic valve; Lung sounds can be achieved in the throat, anterior axillary line, lower part, and middle axillary line and lower part; Auscultation that covers multiple chest auscultation areas such as the posterior axillary line, interscapular area, and subscapular area simultaneously.
■  Using a clinical real stethoscope for auscultation is more closely related to the clinical auscultation effect, and there is no limit on the number of auscultators, achieving simultaneous auscultation by multiple people, suitable for holistic teaching.
■  The bottom of the simulator is equipped with a turntable that can rotate 360 degrees, making it convenient for students to move the simulator in all directions for auscultation.

Chest examination software
The main functions of lung examination
* Pulmonary visual examination function  * Pulmonary palpation function   * Pulmonary percussion function
* Pulmonary auscultation function
Cardiac examination function
* Cardiac visual examination function      * cardiac palpation function    * cardiac percussion     * cardiac auscultation

Abdominal examination simulator
■  Simulate the upper body of an adult female lying on a hard table or hospital bed, with obvious anatomical landmarks for convenient hand positioning during palpation.
■  The simulator can simulate abdominal breathing, with visible ups and downs in the abdomen, which can be classified into three levels: depth, normal, and shallow. Can simulate chest breathing movements, normal breathing movements, and difficulty breathing.
■  It can simulate different degrees of liver and spleen enlargement, and the degree of enlargement can be freely set from 0CM to 8CM.
■  The simulator can simulate tenderness and rebound pain palpation points in at least 13 locations, including gallbladder point, stomach, pancreas point, left quarter rib point/spleen, liver/right quarter rib point, small intestine, appendix tenderness, bladder or uterus, ileocecal, left upper ureteral point tenderness, right upper ureteral point tenderness, left middle ureteral point tenderness, and right middle ureteral point tenderness.

Abdominal examination software
■  The software is mainly divided into four parts: visual examination, auscultation, percussion, and palpation. It systematically describes the content and methods of abdominal visual examination, auscultation, percussion, and palpation.
■  The content of abdominal visual examination includes abdominal surface markers, abdominal shape, respiratory movements, and abdominal wall conditions, including abdominal shape , abdominal wall , abdominal veins, gastrointestinal type, and peristaltic wave and other related content.
■  Abdominal percussion includes at least 9 types of content, including methods of abdominal percussion, boundaries of liver dullness, and areas of gastric vesicle and drum sound; Percussion pain includes content related to rib spinal angle percussion pain and liver area percussion pain.
■  Abdominal auscultation includes at least 6 types of intestinal sounds, 6 vascular murmurs, friction sounds, and scratch tests.
■   Palpation includes at least 11 related contents, including palpation sequence, abdominal wall tension, tenderness and rebound pain, liver palpation, spleen palpation, gallbladder palpation, etc.
