The neonatal umbilical cord care model is a simulation teaching aid designed for neonatal care teaching. Its principle lies in providing trainees with an intuitive and repeatable operation platform by simulating the real structure and physiological characteristics of the neonatal umbilical cord. The model is usually composed of a realistic baby torso and replaceable umbilical cord components. The umbilical cord part can present different states, such as normal umbilical cord, umbilical cord stump, umbilical exudate or signs of infection, helping learners identify and master different care points during training.

The core principle is to simulate the texture and fragility of the umbilical cord through special materials and internal structure design, allowing trainees to experience the real feel of care during operation. During the teaching process, trainees can practice steps such as umbilical cord disinfection, cleaning, bandaging, and dressing change, and cultivate standardized operation habits. Meanwhile, some models are equipped with sensor feedback or replaceable components, which can directly reflect whether the trainees' operations are correct, providing a basis for teaching evaluation.

The significance of this model lies not only in enhancing the proficiency of nursing skills but also in enabling trainees to repeatedly train in a risk-free environment, avoiding the risks and psychological stress associated with directly practicing on newborns. Through systematic practice, students can better master the process and precautions of umbilical cord care, and thus complete the nursing work more calmly and accurately in clinical practice.
