Central venous puncture and intubation model

The central vein puncture and intubation model is a simulation teaching aid specially designed for medical teaching and clinical skills training, which can simulate commonly used central vein puncture sites such as the internal jugular vein, subclavian vein and femoral vein.

Its usage is simple and convenient, and the training effect is intuitive. Before operation, the integrity of the model tubing and the skin surface should be checked first to confirm that the venous channel can be used to draw back the simulated blood.

During training, trainees determine the puncture points on the model based on anatomical landmarks and strictly follow aseptic operation norms for local disinfection, towel laying and anesthesia demonstration. Then, insert the puncture needle to experience the sense of emptiness when the needle tip penetrates the venous cavity, and the success of the puncture can be verified by blood return. Then connect the guide wire and expand the channel. Finally, place the catheter and fix it to complete the entire central venous intubation process.

After the training is completed, the pipelines should be flushed and cleaned in a timely manner to maintain the good condition of the model. This model not only helps medical students and resident doctors master standardized puncture procedures and operational skills, but also effectively reduces clinical operation risks and enhances safety and success rates in practical applications. At the same time, it can also be used for assessment and skills competitions to test the proficiency and standardization of operators. Overall, the central venous puncture and intubation model is of great significance in medical teaching, clinical training and practical exercises.
