The positioning of catheterization model in medical education is extremely important and indispensable. As a teaching aid, it not only provides intuitive and vivid learning experience for medical students, but also greatly promotes the combination of theory and practice, which has far-reaching significance for cultivating clinical skills and professional quality of medical students.

The catheterization model builds a bridge from theory to practice for medical students by simulating the anatomy and operation process of real human body. In the theoretical learning stage, students can understand the basic principles, indications, contraindications and operational procedures of catheterization through the model. In the practical operation stage, students can practice repeatedly on the model and get familiar with the specific operation steps and skills of catheterization, so as to deepen the understanding and mastery of theoretical knowledge.

Compared with the traditional teaching methods, the catheterization model has higher safety and effectiveness. While there are risks and uncertainties associated with performing catheterization on real patients, the catheterization model provides ample opportunity for students to practice without causing any harm. This can not only protect the rights and interests of patients and safety, but also avoid medical accidents caused by tension or improper operation of medical students in actual operation.

Urinary catheterization is one of the commonly used clinical diagnosis and treatment techniques, which plays an important role in relieving the pain of patients with urinary retention and assisting the rescue of critically ill patients. Therefore, mastering urinary catheterization is one of the necessary clinical skills for medical students. Through the practice of catheterization model, students can gradually get familiar with the operation process and skills of catheterization, and improve the accuracy and proficiency of operation. This has important practical significance for them to better serve patients in clinical work in the future.

To sum up, urinary catheterization model plays an extremely important role in medical education. It is a bridge between theory and practice, a safe and effective teaching tool, a key to improving clinical skills and a carrier for cultivating professional literacy. Therefore, attention should be paid to the use and popularization of catheterization model in medical education.
