Main functions of the system: 1.Simulation of vital signs: Bilateral pupil dilation is visually compared with normal, and femoral artery pulsation. 2.Airway management: realistic mouth, nose, tongue, gums, pharynx, larynx, esophagus, epiglottis, and trachea; you can practice orotracheal intubation and sputum suctioning. 3.Intravenous infusion/puncture: arm vein, femoral vein, dorsum of foot vein. 4.Intramuscular injection: bilateral deltoid muscle, bilateral vastus lateralis muscle. 5.Subcutaneous injection: subcutaneously on the outer thigh. 6.Bone marrow puncture: Tibia puncture, obvious body surface signs, simulated bone marrow outflow. 7.Gastric tube insertion: gastric lavage, gastrointestinal decompression operations can be performed, abdominal auscultation is supported to detect the position of the tube, and gastric juice can be aspirated after successful intubation. 8.Catheterization: The male/female perineum can be replaced, and male/female catheterization is possible. 9.Colon, rectum, and cystostomy care. 10.CPR operation training: Various ventilation methods such as mouth-to-mouth, mouth-to-nose, and simple respirator-to-mouth can be performed; airway opening, number of blows, frequency of blows, volume of blows, number of compressions, frequency of compressions, compression positions and depth of compression. Automatically determine the ratio of artificial respiration to chest compressions. Real-time data display, the entire process is displayed in Chinese. 11.Cardiopulmonary auscultation: It can cooperate with the simulator to auscultate and identify more than 100 sound sources, including: normal and abnormal heart sounds, respiratory sounds, bowel sounds and vascular murmurs. 12.ECG monitoring: Can perform ECG monitoring function. 20 types of electrocardiograms are stored internally. 13.Real defibrillation and pacing: Used in conjunction with a self-prepared real defibrillation pacemaker, it can perform real defibrillation and pacing.
