[0002] Anti-bite devices are primarily designed for patients experiencing seizures or psychiatric episodes to prevent them from biting their tongues or lips. These devices are often placed inside the patient's mouth. However, ordinary tongue depressors are often too hard and can easily damage the oral mucosa, failing to address the immediate problem for patients who have bitten their tongues. Currently, two types of tongue depressors are used clinically: one is a disposable wooden tongue depressor, mainly used for oral examinations and assisting with medication and treatment. Its advantages include being economical, practical, and low-cost. Disadvantages include being fragile, easily broken, and having an oval, thin shape that is inconvenient to handle and unsuitable for children. The other type is a stainless steel tongue depressor, mainly placed in an oral care kit for repeated sterilization and use. Its advantages include being wear-resistant, durable, and able to withstand greater force; disadvantages include the hardness of the metal material, which can easily damage the mucosa, and its oval, thin shape that is inconvenient to handle and unsuitable for children. Therefore, appropriate technical solutions are needed to address these existing technical problems. Utility Model Content
