The three-chamber two-capsule operation training model is a simulation teaching aid specifically designed for urology and catheterization nursing instruction, aiming to assist medical students and nursing staff in mastering complex catheterization operation skills.

This model is usually designed based on the anatomical structure of the human lower urinary tract, featuring realistic simulation functions of the bladder, urethra, and three lumen and two cystic ducts, enabling trainees to intuitively understand the placement principle of the urinary catheter and the functions of each lumen. During the training process, trainees can perform operations such as bladder irrigation, indwelling catheterization, and balloon inflation through the model, familiarizing themselves with the operation steps, force control, and pipe fixation methods, thereby effectively enhancing their skill proficiency and safety.

Repeated practice with this model not only reduces the risks of operating on real patients but also helps trainees establish standardized operation habits. In addition, this model can also be used for skills assessment and clinical training demonstrations, enabling teachers to visually explain the key points of operation and precautions.

Overall, the three-chamber and two-capsule operation training model plays a significant role in teaching, skills training, and the cultivation of standardized clinical operations, serving as an important bridge for the integration of theory and practice.
