The intramuscular injection model is a commonly used training tool in nursing and medical teaching. Its main function is to help trainees master standardized intramuscular injection operation skills.

Firstly, the model is made based on the anatomical structure of common injection sites such as the buttocks, thighs or upper arms of the human body. The outer skin is soft, and a simulated muscle layer is set inside, which can truly reproduce the feeling of needle insertion, allowing trainees to become familiar with the puncture Angle, depth and fixation method.

Secondly, the model can be repeatedly operated. During the training process, trainees can directly experience the injection differences in different parts and correct common mistakes in operation, such as Angle deviation, too shallow or too deep needle insertion, etc.

Secondly, some models are designed with injection feedback systems that can show whether the injection has reached the correct level, thereby enhancing the accuracy and effectiveness of training.

In addition, the model avoids the risk of repeated practice on real human bodies, ensuring the safety and efficiency of the learning process. Overall, the intramuscular injection model provides a safe, intuitive and repeatable training platform for nursing students and medical staff, which is conducive to improving clinical operation skills and professional confidence.
