Intelligent cardiopulmonary examination and abdominal examination comprehensive training system (master computer for teachers)

1.  Simulated Patient: Lifelike appearance. The skin of the standardized simulated patient is made of imported 

high-quality high polymer material. Its advantages are non-toxic, odorless, excellent color fastness, 

soft yet resilient (tensile strength ≥2MPa), tear-resistant, excellent tensile properties, and long service life. 

Skin texture is realistic, and superficial anatomical landmarks are accurate.

2.  Organ & Site Simulation:

 Lung Auscultation: Various normal breath sounds and their locations are identical to a real person; 

locations for auscultating various abnormal breath sounds, dry/wet rales, and pleural friction rubs are consistent 

with real clinical patients.

Cardiac Auscultation:Includes not only the auscultatory areas for all cardiac valves but also adds necessary 

auscultation sites based on clinical practice. For example: Mitral opening snap is auscultated medial to the apex;

Pericardial knock and pericardial friction rub, ventricular septal defect can be auscultated at the 4th left intercostal 

space; Left ventricular hypertrophy is auscultated lateral to the midclavicular line.

Cardiopulmonary Palpation: Vividly simulates twelve cardiopulmonary palpation features, 

including various precordial fine tremors, pericardial friction rub sensation, pleural friction rub sensation, 

and tactile fremitus.

3.  Multi-User, Multi-Site Simultaneous Auscultation:The greatest advantage is that it can be auscultated 

using an ordinary stethoscope. It allows multiple users with multiple stethoscopes to auscultate 

different sites simultaneously, fully consistent with clinical practice. This overcomes the limitation of 

"electronic stethoscope" systems where only one person can listen while others watch within a practice group. 

Simultaneous multi-user, multi-site auscultation significantly improves the utilization efficiency of the simulated 

patient, saves considerable time, and can multiply learning effectiveness.

4.  Comprehensive Content & Signs:To make skills training closer to clinical practice and better adapt to the

 teaching needs of different levels in higher medical education, this system includes not only the skills 

training content specified in undergraduate textbooks but also adds a large number of comprehensive 

cardiopulmonary palpation and auscultation signs. This brings the total skills training content to over 350 items, 

making the content richer and the signs more comprehensive.

(1) Simulated Normal Cardiopulmonary Sounds: 

Normal breath sounds can be heard in corresponding areas of the simulated lung model; 

normal heart sounds can be heard in cardiac valve auscultatory areas.(2) Normal Heart Sounds with Lung Pathology Signs:

Normal heart sounds can be heard in all valve areas, combined with palpation signs like tactile fremitus and 

pleural friction rub sensation. Auscultation includes various abnormal breath sounds, dry/wet rales, 

vocal resonance, and pleural friction rubs. Normal bronchial, bronchovesicular, 

and vesicular breath sounds are heard in unaffected lung areas.

(3) Cardiac Palpation/Auscultation Signs with Normal Breath Sounds: 

Palpation includes precordial fine tremors and pericardial friction rub sensation;

 Auscultation includes various abnormal heart rates, rhythms, abnormal heart sounds, cardiovascular murmurs, 

and pericardial friction rubs; Normal heart sounds are heard in unaffected valve areas, 

while various normal breath sounds are heard in corresponding lung areas.

(4) Cardiac Palpation/Auscultation Signs with Lung Pathology Signs: 

Simulates specific cardiac palpation/auscultation signs simultaneously with a lung auscultation sign. 

Normal breath sounds are still heard in unaffected lung areas.

(5) Multi-Valvular Heart Disease (Combined Valvular Disease) with Normal Breath Sounds:

Includes seven types of multi-valvular heart diseases (e.g., Mitral stenosis with aortic insufficiency,

 Mitral stenosis with aortic stenosis, Mitral stenosis with mitral insufficiency, 

Aortic insufficiency with mitral insufficiency, Mitral stenosis with tricuspid and pulmonary insufficiency). 

Normal heart sounds are heard in unaffected valve areas; normal bronchial, 

bronchovesicular, and vesicular breath sounds are heard in the lungs.

(6) Multi-Valvular Heart Disease with Lung Pathology Signs:

The multi-valvular diseases described above are combined with a lung palpation/auscultation sign

 (e.g., tactile fremitus, pleural friction rub sensation, abnormal breath sounds, dry/wet rales, vocal resonance, 

pleural friction rub). Normal breath sounds are still heard in unaffected lung areas.
