The 22cm ear acupuncture model is a portable training tool specially designed for auricular point teaching and demonstration. It clearly presents the anatomical structure of the ear and the locations of commonly used auricular points at an enlarged scale. The model is made according to the standard auricular point zones, with clear markings and distinct color distinctions, facilitating learners to quickly identify key areas such as the auricle, helix, and conchal cavity, as well as their corresponding acupoints. It is compact in size and easy to operate, making it highly suitable for classroom teaching, training demonstrations and health science popularization activities.

In teaching, this model can help beginners establish the concept of spatial positioning of auricular points and understand the corresponding relationship between the reflex zones of the ear and all the internal organs of the body. Teachers can visually display the acupoint selection methods, pressing directions and common health-preserving acupoints on the model to enhance the learning effect. The model is also applicable to non-invasive training such as auricular point pressing and demonstration of auricular bean positions, making the learning process safer. For learners of traditional Chinese medicine, rehabilitation institutions and health care practitioners, the 22cm ear acupuncture model is an efficient teaching aid tool that combines practicality and portability.
