Critical emergency rescue is a condition which is necessarily met by each doctor, and a plurality of emergency rescue technologies such as central venipuncture, mechanical ventilation, hemodynamic monitoring, blood purification, tracheal intubation and the like are key for successfully rescuing patients. In these techniques, rapid and accurate central venous catheterization is often the basis of rescue and is also a content which is frequently encountered in clinic and difficult to self-learn.
The effective training of the central venous catheterization is very important, so that not only can young doctors comprehensively and firmly master the technology, but also the emergency treatment and the overall hospital rescue medical safety can be improved. But the current society has even highlighted the concern about medical safety. In actual clinical work, the enhancement of the law awareness and the self-protection awareness of patients obviously reduces the chances that medical students who do not acquire medical qualification practice on actual patients. This severely limited the clinical capacity of medical students. In addition, the young clinicians have insufficient mastery, are not precise and often make mistakes in the technique of central venous catheterization, which causes serious consequences for patients, such as leaving the central venous catheterization in the body of the patients, and similar serious adverse events occur every year.
Internal jugular vein puncture is the most common technique for central vein puncture, and is a basic operation skill which must be mastered by medical practitioners, especially medical practitioners in emergency departments, ICUs, anesthesia departments and the like.

Some present emulation dark vein puncture models, though play certain teaching effect, the price is very expensive, and the volume is great, and teaching unit is difficult to purchase in batches, leads to the lacked of puncture model, and the teaching effect obviously reduces. At present, no teaching tool which is safe, simple, practical and cheap is provided, so that each person can practice for many times in the accompanying training process, and the teaching tool is suitable for simulation practice of multiple scenes. The medical education is an improved teaching direction by observing the current medical education, finishing the preset teaching target in limited teaching time with high efficiency and obtaining social recognition.
