Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, in particular to a device for preventing tongue biting during epileptic seizures. BACKGROUND

[0002] Epilepsy is a chronic neurological disorder characterized by recurrent seizures resulting from abnormal excessive discharges of neurons in the brain. The most typical, common, and riskiest type of seizure is generalized convulsive seizure (commonly known as "grand mal seizure"). During the seizure, patients often lose consciousness, experience muscle rigidity and clonus, and involuntary strong contraction of the masseter muscle, which causes the upper and lower teeth to bite each other. During the rigidity and clonus phases, the tongue is easily bitten, and in severe cases, it can cause tongue laceration, bleeding, and even suffocation, which are life-threatening complications.

[0003] To prevent tongue biting during grand mal seizures, various protective measures have been tried in clinical practice. Early methods include placing foreign objects such as tongue depressors, spoons, towel rolls, or wooden / plastic mouth guards in the patient's mouth to try to create a physical barrier between the upper and lower teeth. However, these traditional methods have significant drawbacks: on the one hand, during the early stages of a seizure, the patient often quickly enters the rigidity phase, and the masseter muscle contracts strongly, causing the teeth to close tightly. At this time, forcibly inserting foreign objects is not only difficult to operate, but also easily causes tooth damage, laceration of the oral mucosa, and may block the airway, leading to suffocation of the patient; on the other hand, if a protective device is placed in the mouth before the seizure, it is difficult to wear for a long time due to the patient's inability to cooperate or the device's discomfort, and there are safety hazards such as falling out or being swallowed.
