The main function of the training model for children's femoral vein and femoral artery puncture is to provide medical students and nursing staff with a safe and repeatable operation platform, in order to solve the problems of high difficulty and high risk in children's vascular puncture operations. Children have small blood vessels and soft skin. Puncture operations are prone to failure or cause vascular damage, bleeding or even infection. However, repeated practice on real children poses significant risks. This training model is designed based on the anatomical proportions of the femoral artery and femoral vein in children, clearly showing the position, direction and depth of the blood vessels, and can simulate blood flow and pulse, which is convenient for learners to identify the puncture point and master the operation feel.

Through model training, learners can repeatedly practice the correct puncture posture, needle Angle, depth control and catheter fixation methods, while mastering the skills of hemostasis and complication management. Some high-fidelity models can also be used to simulate different vascular conditions, such as small and fragile blood vessels and other complex situations, to enhance the trainees' ability to deal with special clinical situations. Through standardized operation drills, learners can build operational confidence and proficiency in a risk-free environment, laying a solid foundation for actual clinical operations. Overall, this model not only enhances the safety and efficiency of training in children's femoral vein and femoral artery puncture skills, but also provides a scientific and standardized teaching platform for children's vascular interventional operations.
