The advanced ear examination model is a simulation device used for clinical teaching and skills training in otology, mainly for learning otoscopy examination, lesion identification and basic operation skills. The following points should be noted during use:

First of all, before operation, it is necessary to ensure that the model is clean and intact to prevent dust or impurities from entering the ear canal simulation cavity and affecting the observation effect.

Secondly, when inserting otoscopes or other instruments, trainees should be gentle and avoid excessive force to prevent damage to the fine internal structures of the model.

Secondly, if the model has multiple lesion replaceable or electronic display functions, it should be operated in accordance with the instructions to avoid frequent disassembly and assembly which may cause wear and tear. During training, it is necessary to pay attention to keeping the light source and lens clear to ensure the authenticity of the observation effect.

After the operation is completed, the power supply should be turned off in time (if it is equipped with an electronic system), and the surface should be wiped with a soft dry cloth or a special cleaning tool. Do not use strong corrosive cleaning agents. When properly stored, it should be kept away from moisture or direct strong light to extend the model's lifespan. Through reasonable use and maintenance, this model can provide stable and intuitive training support for otology teaching.
