Main functions:

1. The upper body of an adult male can be punctured at 18 locations;

2. Various body positions for puncture operation include: supine position, sitting position, left and right lateral lying position, prone position;

3. The 18 puncture sites include: right internal jugular vein puncture, right subclavian vein puncture, right external jugular vein puncture, right femoral vein puncture, right cervical lymph node puncture biopsy, left pleural cavity puncture (2 fluid chests, 1 pneumothorax, 3 in total), liver puncture and aspiration, right kidney puncture, lumbar puncture, peritoneal cavity puncture, intracardiac injection Bone marrow puncture (right anterior superior iliac spine, right posterior superior iliac spine and sternum), left elbow joint injection (expandable function), right infusion arm (expandable function);

4. The console is equipped with human figure, marked with the above puncture position, and the indicator light indicates the current operation;

5. Before puncture operation, corresponding voice explanation shall be provided to explain correct operation position, puncture point and process, correct positioning, correct operation or incorrect operation with prompt tone;

6. If the puncture site is different and the content is different, the yellow simulated pus can be drawn from the correct liver puncture; Blood fluid can be drawn out by intracardiac injection to distinguish the puncture position; Bone marrow puncture can extract simulated bone marrow fluid; The blood fluid was drawn back through arteriovenous puncture; Pneumothorax puncture can discharge gas;

7. The body surface signs used for positioning of each operation are obvious (such as sternocleidomastoid muscle, scapula, xiphoid process, anterior superior iliac spine, umbilical cord, etc.), the anatomical structure is clear, and there are automatic carotid and femoral artery pulsations to facilitate positioning;

8. The position and scope of pneumothorax and hydrothorax, abdominal movable dullness and liver dullness can be examined by percussion;

9. Pre operation aseptic operation training can be carried out: wear sterile gloves before operation, and the puncture site should be routinely disinfected (replaced with water), towel laying, post-operative treatment and other operation procedures;
