Lung anatomy models are commonly used demonstration tools in medical teaching and health science popularization. To ensure their effectiveness and extend their lifespan, certain operation norms need to be followed.

First of all, before use, the integrity of the model should be checked to ensure that there is no damage to details such as the lung lobes, bronchi, and blood vessels. If it is a detachable design, make sure the connection parts are firm. During operation, handle with care and avoid excessive force to prevent damage.

Secondly, the demonstration should be carried out in an orderly manner. First, the overall structure can be presented, and then the left and right lungs and lung lobes can be gradually disassembled for explanation, combined with the bronchial tree and the direction of blood vessels. After disassembly, it should be reset in time to form a complete spatial concept, which helps learners understand the anatomy and function of the lungs more intuitively.

Secondly, if the model has a base or magnetic interface, it is necessary to ensure that it is securely fixed to prevent shaking or falling off during the demonstration. After use, clean the surface with a soft dry cloth. Avoid strong corrosive cleaning agents to maintain the color and details of the model.

Finally, the model should be stored in a dry and well-ventilated environment, avoiding high temperatures and direct sunlight to extend its service life. By following the above norms, not only can the standardization of teaching be ensured, but also the value of the model in medical education can be fully exerted.
