Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a tongue-biting prevention device for epilepsy patients in an emergency department. Background Art

[0002] Epilepsy is a common neurological disease that affects many patients worldwide. The causes of the disease are diverse, such as genetics, brain diseases, etc. During an attack, brain neurons discharge abnormally, and patients lose consciousness and have convulsions, which seriously affect their lives. Although medical research is ongoing, there are still unsolved mysteries. Treatment requires a combination of multiple methods. Although it is difficult, there is hope. We look forward to better controlling it, allowing patients to regain normal life and get rid of the shadow of the disease.

[0003] Epilepsy patients tend to bite their tongues during an attack. When an epileptic seizure occurs, they use their hands to pry open their jaws. They need to quickly roll up items such as handkerchiefs and gauze and place them between the patient's upper and lower teeth to prevent the patient from biting his tongue when his teeth are clenched.

[0004] When a patient becomes ill, medical staff take measures to directly open the patient's mouth. The medical staff's hands are easily bitten by the patient, causing infection and health risks to the medical staff. Using tools to pry open the patient's mouth can easily cause the patient's teeth to break, thereby causing harm to the patient. In addition, when dealing with this situation, multiple medical staff are required to cooperate, wasting manpower. Summary of the invention

[0021] Working principle: First, place the rotating mechanism with a rotatable function on both sides of the patient's head, then place the anti-bite mechanism with a spreading mechanism on one side of the patient, and then rotate the U-shaped turning plate by holding the handle, accurately align the spreading mechanism with the patient's chin, and then press the slide bar to make the spreading plate contact the patient's chin. At this time, the locking rod of the locking mechanism will engage with the locking tooth groove. Since the locking rod is triangular and the inclined surface is upward, when pressing downward, the locking tooth groove will squeeze the locking rod, causing the locking rod to expand outward, thereby causing the moving rod to drop. After reaching the appropriate position, spring 2 will squeeze the slider, and the slider will squeeze the locking rod again, causing the locking rod to engage with the locking tooth groove again. At this time, pull the handle backward and the spreading plate will drive the patient Chin, open the patient's chin, then put the anti-bite mechanism with a spreading mechanism on one side between the patient's teeth, then remove the spreading mechanism, place the pad on the patient's chin, then rotate the knob, and drive the screw to rotate through the knob, so that the U-shaped plate fixed on the fixed block 2 slides on the fixed rod, thereby driving the top dental plate to expand, open the mouth, and then put the elastic band on the patient's head, one elastic band is put under the ear, and the other is set above the ear. By adjusting the adjustment buckle on the elastic band, the elastic band can be adapted to the patient's head circumference to prevent the patient from knocking off the device to avoid biting the tongue. Finally, carefully observe the patient's mouth to check the length and depth of the tongue laceration, whether the teeth are loose or broken, etc.

[0022] The present invention provides a tongue-biting prevention device for epilepsy patients in the emergency department. It has the following beneficial effects:

[0023] 1. The present invention, through the close cooperation between the anti-bite mechanism and the opening mechanism, the anti-bite mechanism can effectively prevent tongue bites in situations such as epileptic seizures by means of the coordinated operation of the upper outer cover, the lower outer cover and the top tooth plate, and effectively protect the patient's oral safety. The opening mechanism relies on the coordinated operation of the fixing block, the fixing rod, the U-shaped plate, the screw rod and the knob to open the mouth to rescue the patient and provide convenience for medical staff to conduct examinations and treatments. At the same time, the adjustment buckle design can be flexibly adjusted according to the head circumference of different patients, ensuring that the device is firmly worn on the patient's head, adapting to individual differences, and effectively preventing dangerous situations caused by improper wearing.

[0024] 2. The present invention relies on the synergistic effect of the rotating mechanism and the spreading mechanism to make the operation more convenient and precise, allowing medical staff to easily spread the patient's chin to a suitable position for smooth treatment. The moving rod of the spreading mechanism has the function of adjusting the position, and its adjustment component effectively guarantees the safety and accuracy of the operation.
