The basic nursing practice model plays an important role in medical education and clinical practice. These models provide a safe, risk-free environment for healthcare professionals to simulate and practice a variety of basic care operations, thereby improving their skills and proficiency. Whether the model contains replaceable or cleanable parts depends mainly on the design of the model and the manufacturer's considerations.

First, from a design perspective, modern primary caregiver practice models tend to be modular in design, meaning that different parts of the model can be separated from each other for easy replacement or cleaning by the user. This design enables the model to maintain its teaching value and practicality after a long time of use.

Secondly, considering the cleanliness and hygiene of the model, many manufacturers will equip the model with cleanable parts. These parts are typically made of durable materials that can withstand routine cleaning and disinfection. By cleaning and disinfecting the model regularly, the hygienic condition of the model during use can be ensured, thus avoiding the risk of cross-infection.

However, it is important to note that not all primary caregiver practice operating models contain replaceable or cleanable parts. Some older or lower-end models may have an integral design whose parts cannot be separated or replaced. In addition, even if the model has replaceable parts, there may be cases where certain parts cannot be cleaned. Therefore, when purchasing a model, the user needs to carefully review the product description and the information provided by the manufacturer to understand the detailed design and functionality of the model.

For models containing replaceable or cleanable parts, users need to follow the manufacturer's guidelines and recommendations for proper replacement and cleaning operations during use. This not only ensures the performance and longevity of the model, but also improves the safety and hygiene of the user.

In summary, whether a primary caregiver practice operating model contains replaceable or cleanable parts depends on its design and manufacturer's considerations. When purchasing a model, users should carefully review the product description and the information provided by the manufacturer, and follow the relevant guidelines and recommendations. By selecting and using the model correctly, its value in teaching and clinical practice can be maximized.
