The covered dialysis model is a specialized training tool used to simulate peritoneal dialysis operations and teaching, and it plays an important role in clinical education and skills development. This model is designed based on the structure of the human abdomen, with a simulated peritoneal cavity set inside. It can clearly demonstrate the inflow, outflow and peritoneal absorption processes of dialysis fluid, enabling learners to intuitively understand the principle and operation process of peritoneal dialysis. Through model training, students can master the selection of puncture points, catheter fixation, dialysis fluid injection and reflux operations, as well as possible abnormal situations during the operation, thereby enhancing their proficiency and safety in clinical operations.

In teaching, teachers can use models to demonstrate the entire process of peritoneal dialysis, including disinfection, puncture, catheter management and complication handling, which is convenient for students to repeatedly practice in a risk-free environment and form standardized operation habits. The model is also applicable to nurse skills assessment, clinical novice training and patient education, enabling patients and their families to have an intuitive understanding of the dialysis process and improve their self-management ability. Overall, the covered dialysis model is an important tool for integrating peritoneal dialysis theory with practice, and it plays a significant role in improving clinical operation levels and nursing quality.
