Group based chest examination teaching system

System Overview
■  The system mainly consists of two simulated chest examinations, one simulated abdominal examination, 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 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 interface is vivid and the operation is simple, reducing the intensity of teachers' theoretical teaching in diagnosis and internal medicine, and improving teaching and assessment effectiveness.
■  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 simulated human
■  Simulate the real skeletal structure of a human lining, with clear body surface markings and a realistic, soft, and smooth skin feel, meeting the needs of body surface positioning.
■  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.

Abdominal examination simulated human
■  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 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.
■  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.
■  The system has the functions of question screening, paper management, random question setting, teacher's independent topic selection, automatic grading, saving of papers, and viewing of grades.
