The pediatric catheterization model is a simulation teaching aid specially designed for the training of children's care skills, which can help trainees master the standard procedures and precautions of pediatric catheterization operations. This model is made based on the anatomical structure of the urinary system in children, with a realistic appearance and clear urethral channels. It can simulate the resistance and feedback that may be encountered during catheterization, making it convenient for repeated practice.

In terms of operational norms, it is first necessary to strictly adhere to the principle of aseptic operation and prepare catheters, lubricants, disinfectants and urine collection devices. At the beginning of the training, disinfect the urethral orifice and perineum of the model first. Then, apply an appropriate amount of lubricant to the catheter and slowly insert it into the urethra, paying attention to moderate force to avoid damaging the simulated urethra. When the catheter enters the bladder and urine reflux occurs, it indicates that the catheterization is successful. Subsequently, the catheter was fixed and connected to the collection device to complete the simulated catheterization operation.

Throughout the entire training process, trainees should pay attention to the sequence of operations, gentle techniques and simulate the flow of urine. Through repeated practice, they should master the skills of pediatric catheterization. This model not only enhanced the practical operation ability of the trainees, but also strengthened their confidence in handling pediatric urological care operations, providing a solid foundation for clinical practice.
