The role of intradermal injection models for the arm

The function of the intradermal injection model of the arm is to help medical staff and nursing students systematically master the standard operation skills of intradermal injection.

The model is designed based on the real proportion of the human upper arm. The skin is soft in texture and has good elasticity, which can realistically reproduce the skin's layering structure, enabling trainees to correctly identify the Angle, depth and direction of needle insertion.

During operation, the model can generate a "pitchulus" phenomenon similar to real skin, helping trainees determine whether the injection was successful. Through repeated practice, users can become familiar with the feeling of injecting the liquid medicine and the local reaction after injection, and cultivate accurate and stable operation habits.

This model is also convenient for teaching demonstrations and assessments. Teachers can directly evaluate whether the trainees' techniques are standardized. Its application effectively increases the success rate of intradermal injection, reduces risks and patient discomfort in clinical practice, and provides a safe, economical and efficient teaching tool for basic nursing skills training.
