Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an anti-tongue biting device for epilepsy. Background Technology

[0002] Epilepsy is a chronic, recurrent, and transient syndrome of brain dysfunction, characterized by recurrent epileptic seizures caused by abnormal electrical discharges in brain neurons. Epilepsy is one of the most common neurological disorders, second only to stroke in prevalence. The most severe form of seizure is the tonic-clonic seizure, characterized by sudden loss of consciousness, followed by tonic and then clonic spasms, often accompanied by a scream, cyanosis, urinary incontinence, and tongue biting. To prevent patients from biting their tongues during seizures, a dental pad or a tongue depressor wrapped in thick gauze is usually placed between the patient's upper and lower molars. However, this method requires medical staff to hold the tongue constantly; moreover, patients may experience foaming at the mouth or excessive saliva, which can easily cause choking.

[0030] According to some embodiments of this utility model, refer to Figures 1 to 4The anti-tongue-biting device for epilepsy includes a housing 100, a suction assembly 200, and two toothed assemblies 300. The housing 100 has its opening facing forward. The suction assembly 200 includes a cylinder 210, a piston rod 220, and a slide 230. The axes of the cylinder 210 and the piston rod 220 are both in the front-back direction. The cylinder 210 is inserted through and rotatably connected to the housing 100, and can rotate relative to the housing 100 around its own axis. The front end of the piston rod 220 is inserted into and slidably connected to the cylinder 210 in the front-back direction. The slide 230 is located inside the housing 100 and is sleeved and threadedly connected to the cylinder 210. The front end of the cylinder 210 has a suction port 241 communicating with the inner cavity of the cylinder 210. The two toothed assemblies 300 are symmetrically arranged in the vertical direction, and are located on the upper and lower sides of the cylinder 210, respectively. The toothed assembly 300 includes a slider 310, a limiting rod 320, a swing arm 330, and a toothed sleeve 340. The slider 310 is located inside the housing 100 and is fixedly connected to the slide block 230. The slider 310 is slidably connected to the housing 100 in the front-to-back direction. The slider 310 has an elongated through hole 350, which extends vertically. The axis of the limiting rod 320 is in the left-to-right direction and passes through the elongated through hole 350. The swing arm 330 is arc-shaped and rotatably connected to the housing 100 at its middle part. One end of the swing arm 330 is rotatably connected to the limiting rod 320, and the other end of the swing arm 330 is fixedly connected to the toothed sleeve 340, which is located on the front side of the housing 100. The dental brace 340 has a groove 360 ​​on the side away from the other dental brace 340. That is, the upper end of the upper dental brace 340 is concave downward to form a groove 360, and the lower end of the lower dental brace 340 is concave upward to form a groove 360. When the cylinder 210 rotates relative to the shell 100, the slide 230 slides relative to the cylinder 210 in the front-back direction. The limiting rod 320 moves back and forth along the extension direction of the elongated through hole 350, thereby driving the swing arm 330 to rotate, so that the two dental braces 340 move closer or further apart in the vertical direction.

[0031] When using this epilepsy anti-tongue-biting device, after opening the patient's jaw, the two dental sleeves 340 of the dental sleeve assembly 300 are placed into the patient's oral cavity, so that the patient's upper teeth are inserted into the alveoli 360 of the upper dental sleeve 340 and the lower teeth are inserted into the alveoli 360 of the lower dental sleeve 340. By rotating the cylinder 210, the slide 230 is moved forward, which in turn drives the swing arm 330 to rotate, causing the two dental sleeves 340 to move away from each other, thereby further widening the size of the patient's jaw. Since the threaded connection between the slide 230 and the cylinder 210 is self-locking, it avoids the need for medical staff to continuously manually open the patient's jaw. Moreover, the front end of the cylinder 210 is inserted into the patient's oral cavity, and the piston rod 220 can be used to remove foam and saliva in the oral cavity, preventing the patient from choking.

[0032] According to some embodiments of this utility model, refer to Figure 1 and Figure 2 The epilepsy anti-tongue-biting device also includes a tongue depressor 370, with the dental sleeve 340 of the lower dental sleeve assembly 300 fixedly connected to the rear side of the tongue depressor 370. When the patient presses down into the alveolar 360 of the lower dental sleeve 340, the lower end face of the tongue depressor 370 can press the tongue down, preventing the tongue from moving around and causing injury.

[0033] According to some embodiments of this utility model, refer to Figure 4 The shell 100 has straps 400 on both its left and right sides. These two straps 400 work together to secure the shell 100 to the human body. When the two alveoli 360 are inserted into the human mouth, the two straps 400 can wrap around the head and tighten together, thus fixing the shell 100 to the body. Preferably, see reference... Figure 1 The front side of the shell 100 is recessed to form an arc-shaped groove 130. The depth of the arc-shaped groove 130 gradually increases towards the center along the left and right direction, so as to adapt to the shape of the human mouth and make it easy for the arc-shaped groove 130 to fit the human mouth.

[0034] According to some embodiments of this utility model, refer to Figure 2 The inner wall of the housing 100 is provided with a slide groove 110 extending in the front-back direction. The side of the slider 310 away from the slide block 230 is inserted into the slide groove 110 and can slide in the front-back direction. The slide groove 110 can restrict the slider 310 from rotating. Since the slider 310 and the slide block 230 are relatively fixed, the slide block 230 is prevented from rotating with the cylinder 210, ensuring that the slide block 230 moves in the front-back direction during the rotation of the cylinder 210.

[0035] According to some embodiments of this utility model, refer to Figure 2 The rear end face of the housing 100 is provided with a bearing 120, and the cylinder 210 passes through the bearing 120 and is fixedly connected to the inner peripheral wall of the bearing 120.

[0036] According to some embodiments of this utility model, refer to Figure 1 and Figure 4 The alveolar bone 360 ​​is arc-shaped, and both ends of the alveolar bone 360 ​​penetrate the front side of the braces 340.

[0037] According to some embodiments of this utility model, refer to Figure 3The cylinder 210 is equipped with a filter screen 250, which divides the inner cavity of the cylinder 210 into a gas zone 261 and a liquid zone 262. The gas zone 261 is located behind the liquid zone 262, and the liquid zone 262 is connected to the suction port 241. The filter screen 250 has tiny pores, which prevent liquid in the liquid zone 262 from entering the gas zone 261, while gas in the gas zone 261 can pass through the filter screen 250 into the liquid zone 262. The front end of the piston rod 220 is inserted into the gas zone 261, and the front end of the piston rod 220 is equipped with a sealing gasket 270, the outer peripheral wall of which is attached to the inner peripheral wall of the cylinder 210.

[0038] Preferred, refer to Figure 3 The cylinder 210 is provided with a drain channel 280 and a liquid outlet 290. One end of the drain channel 280 is connected to the liquid zone 262, and the other end of the drain channel 280 is connected to the liquid outlet 290. The liquid outlet 290 is connected to the outside. A first one-way valve 410 is provided in the liquid zone 262 to prevent liquid and gas in the liquid zone 262 from flowing out from the suction port 241. A second one-way valve 420 is provided in the liquid outlet 290 to prevent external gas and liquid from entering the drain channel 280 through the liquid outlet 290.

[0039] Preferred, refer to Figure 3 The first one-way valve 410 includes a first return spring 411 and a first ball 412. The front end of the first return spring 411 is connected to the first ball 412, and the rear end of the first return spring 411 is connected to the filter screen 250. The first ball 412 is used to block the liquid suction port 241.

[0040] Preferred, refer to Figure 3 The second one-way valve 420 includes a second return spring 421 and a second ball 422. The front end of the second return spring 421 is connected to the second ball 422, and the rear end of the second return spring 421 is connected to the cylinder 210. The second ball 422 is used to block the drain channel 280.

[0041] When the piston rod 220 is pulled back, the pressure in the air zone 261 decreases, and the external gas overcomes the force of the first return spring 411 to push the first ball 412 back, thereby opening the suction port 241. Foam and saliva in the mouth can enter the air zone 261 through the suction port 241, while the external gas cannot pass through the second one-way valve 420.

[0042] When the piston rod 220 is pushed forward, the pressure in the gas zone 261 increases, and the gas cannot pass through the first one-way valve 410, which increases the gas pressure in the drainage channel 280. This overcomes the force of the second return spring 421 and pushes the second ball 422 backward, thereby connecting the drainage channel 280 and the outlet 290. The foam and saliva in the gas zone 261 enter the drainage channel 280 and are discharged through the outlet 290.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
