Advanced cannula needle training model

The advanced cannula needle training model is a highly realistic teaching aid specially designed for medical teaching and clinical skills training, mainly used for venipuncture, cannula needle insertion and related operation training. This model is made based on the anatomical scale of the human arm or vein, and is equipped with a built-in simulated vascular system that can circulate and return simulated blood, providing learners with an experience environment close to real operation.

During the training process, learners first need to observe the venous distribution of the model and select the appropriate puncture point. Subsequently, disinfection, skin fixation and needle insertion practice were carried out in accordance with the standard operating procedures, and the resistance changes of the needle tip entering the blood vessel were perceived by hand. The model's function of drawing back blood enables trainees to visually determine whether the puncture was successful and master the techniques of pushing and pulling out the cannula needle.

This model is not only suitable for basic training, but also can be used to simulate complex operations, such as multiple punctures, venous rotations or operation practices under different vascular conditions. Some high-end models are equipped with electronic feedback systems that can immediately indicate whether the operation is standardized, helping learners correct their techniques and improve the accuracy and safety of puncture.

Overall, the advanced cannula needle training model provides a safe and repeatable practice platform for medical students, nurses and clinical novices. It can effectively improve intravenous operation skills, enhance confidence and proficiency in actual clinical operations, and is an indispensable important tool in modern medical teaching.
