The head acupuncture model is a specialized tool used for teaching and practical training in traditional Chinese acupuncture. The model is marked with the positions of the main meridians and acupoints on the head, which can help learners master the key points of acupoint selection and operation on the head. During the usage process, to ensure the teaching effect and the lifespan of the model, the following matters should be noted.

First of all, before use, check whether the surface of the model is intact and whether the acupoint markings are clear to avoid teaching errors caused by wear or blurring. If stains are found, they can be gently wiped with a clean soft cloth. Avoid using strong chemical solvents to prevent damage to the surface layer.

Secondly, in teaching demonstrations, instructions or simulated operations should be strictly carried out in accordance with the meridians' directions and the positions of acupoints. If needling training is to be conducted, special teaching AIDS and needles should be used instead of real needles to prevent puncturing the model or causing unnecessary safety risks.

Secondly, when operating, handle with care to avoid heavy pressure, bending or prolonged exposure to direct sunlight, to prevent the model from deforming, fading or aging. When storing, it is advisable to keep it in a dry and well-ventilated place, away from high-temperature and humid environments.

Finally, during the students' practice process, teachers should enhance guidance to ensure the standardization of acupoint identification and operation methods.

By taking the above precautions, the head acupuncture model can not only maintain a good state but also maximize its role in teaching and training.
