Description

Technical Field

[0001] The present invention relates to the technical field of tongue bite prevention devices, and in particular to a tongue bite prevention protection device for psychiatric psychology and a use method thereof. Background Art

[0002] For patients in the psychiatric department, or those with physical illnesses, if they lack self-control, are dominated by auditory hallucinations or delusions, or cannot endure the torture of mental and physical illnesses, they may engage in behaviors such as self-harm and suicide. Among them, tongue biting is a relatively common form of self-harm. The reason for this behavior may be due to the patient's subjective consciousness or it may be due to the patient suffering from diseases such as epilepsy. This behavior may not only cause tongue injury to the patient, but may even endanger life in severe cases. At present, some products have appeared to prevent patients from biting their tongues, but these products all have many problems, such as inconvenience in use, poor comfort and complex structure.

[0003] Existing tongue-biting prevention devices, such as a tongue-biting prevention device for psychiatric psychology provided by publication number CN213283465U, include upper braces, lower braces, arc-shaped tracks, latches, fixing grooves, limiting mechanisms, and fixing mechanisms. First, the device can be fixed to the patient's teeth by using the upper braces and the lower braces together, and then the closing angle of the patient's teeth can be limited by the limiting mechanism. At the same time, the device can be fixed to the patient's teeth by the fixing mechanism, and is not easy to fall off, which effectively solves the problem that the patient's tongue is easy to bite because the dental pad is easy to fall off; however, since the device requires medical staff to use a hexagonal wrench to turn the bolt clockwise when in use, the two fixing blocks are driven to squeeze the patient's teeth and fix them, that is, the patient is prevented from biting by the fixed structure. Although this method can prevent the patient from biting the tongue in the short term, the patient's anxiety will become more severe because the oral cavity is in an immobile fixed state, which may lead to other dangerous behaviors of the patient. At the same time, the application needs to use a wrench to adjust the bolt in actual use, which is inconvenient to operate. Summary of the invention

[0004] In view of the above-mentioned problems, the present invention aims to provide a protective device for preventing tongue bite in the department of psychiatry and psychology. By designing an anti-bite component, a supporting part and a tongue depressing part are provided on the tooth sleeve, and an adaptive supporting mechanism and a pneumatic supporting mechanism in the supporting part are used to enable the tooth sleeve to support the patient's oral cavity while allowing the patient to bite to a certain extent. By fixing a tongue depressor structure on the upper and lower parts of the tooth sleeve, the patient's tongue can be pressed back into the oral cavity when the patient bites, thereby preventing the patient from biting the tongue. The device has the advantages of good safety, easy use, high comfort and simple structure.

[0005] The main idea of ​​the technical solution adopted by the present invention is to design an anti-bite component, by designing a support part on the tooth sleeve that allows the patient to bite to a certain extent, by nesting a memory alloy wire and a support ring on the tooth sleeve to form an adaptive support mechanism, and adaptive support is performed when the patient bites the tooth sleeve, by arranging support airbags and side airbags on both sides of the tooth sleeve to form a pneumatic support mechanism, when the tooth sleeve is bent and closed, gas is input into the support airbags through the side airbags to support both sides of the tooth sleeve through the support airbags, and when the tooth sleeve is bent, the tongue depressor can press the patient's tongue back into the oral cavity, and the tongue depressors located on the upper and lower sides of the tooth sleeve can press the patient's tongue back into the oral cavity to prevent the patient from biting the tongue when the disease occurs.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A protective device for preventing tongue bite in the psychiatric department comprises a tooth sleeve, connecting plates are provided on both sides of the tooth sleeve, straps are rotatably provided between the connecting plates on both sides, and an anti-bite component for preventing psychiatric patients from biting their tongues is provided on the tooth sleeve.

[0007] The anti-bite component comprises a supporting part for supporting the tooth sleeve and a tongue depressing part for pressing the tongue back into the oral cavity.

[0008] The support portion comprises an adaptive support mechanism, and the adaptive support mechanism comprises a support ring nested on the gear sleeve and a memory alloy wire.

[0009] Based on the above technical solution, further, the material of the support ring is D3O material.

[0010] The support part also includes a pneumatic support mechanism, which includes a support airbag fixed on the gear sleeve, and side airbags are provided in the connecting plates on both sides of the gear sleeve. The side airbags are connected to the support airbags through an air pipe, and the air pipe is provided with an air valve that can input the air in the side airbags into the support airbags.

[0011] Based on the above technical solution, further, fixing plugs are provided on both sides of the gear sleeve, and a connecting block mounted on the support ring is fixed on the fixing plug. One end of the connecting block away from the support ring is fixedly connected to the connecting plate, and when the support ring is bent, it can drive the connecting block to press down and start the air valve to allow the air in the side airbag to be input into the support airbag.

[0012] Based on the above technical solution, further, a concealed bolt capable of preventing the patient from disassembling the connection block by himself is provided at the connection between the connection block and the connection plate.

[0013] The tongue depressor comprises a first tongue depressor fixed at a certain angle to the upper part of the gear sleeve, a second tongue depressor is horizontally fixed to the lower part of the gear sleeve, and the overall length of the first tongue depressor is greater than that of the second tongue depressor.

[0014] Based on the above technical solution, it further includes a pry plate for opening the tooth sleeve, one end of the pry plate is provided with a wrench for removing the hidden bolts, and a storage cavity for placing emergency treatment drugs is provided at the connection between the pry plate and the wrench.

[0015] A method for using a protective device for preventing tongue bite in a psychiatric department comprises the following steps: S1. Fit the tooth guard to the patient's teeth and use a strap to fix the protective device to the patient's head; S2. When the patient bites the tooth sleeve, the adaptive support mechanism limits the closing of the tooth sleeve, and the pneumatic support mechanism is inflated to prevent the tooth sleeve from closing. At the same time, the tongue is pressed back into the oral cavity by the tongue depressor to prevent the patient from biting the tongue; S3. When the device cannot open automatically due to a malfunction, use a wrench to remove the hidden bolts and use the pry plate to open the tooth sleeve to open the patient's mouth.

[0016] The beneficial effects of the present invention are: 1. By designing an anti-bite component and arranging a support collar and a memory alloy wire on the tooth sleeve, when a psychiatric patient bites the tooth sleeve due to illness or other reasons, the biting speed of the tooth sleeve can be limited, providing sufficient time for the start-up of the pneumatic support mechanism, and the connecting block is driven by the support collar to press down the air valve, so that the gas in the side airbag is filled into the support airbag. Through the joint action of the two mechanisms, the tooth sleeve is prevented from closing, so that the patient's mouth retains a gap that can be used for breathing. In addition, when the tooth sleeve is closed, the first tongue depressor presses down the middle part of the patient's tongue, so that the patient's tongue can be retracted into the mouth regardless of whether it is in a state of protruding from the mouth or located above the second tongue depressor, so as to prevent the patient from biting the tongue, so that the present invention has the advantage of good safety.

[0017] 2. When the present invention is in use, the entire device is fixed to the patient's head by a strap, and the tooth sleeve is worn in contact with the patient's teeth. At the same time, the anti-bite component can be automatically activated when the patient bites, and protect the patient's entire oral cavity to prevent biting, and gradually reset when the patient stops biting, making the use of the present invention more convenient and quick.

[0018] 3. By designing an anti-bite component on the tooth sleeve, when the patient bites due to illness or anxiety, the patient's oral permeability and tongue protection can be provided under the premise that the patient is allowed to bite at a certain distance. Compared with the existing devices that only achieve the protection purpose by fixing the mouth, the present invention can relieve the patient's anxiety to a certain extent and improve the patient's comfort when using it. At the same time, the overall structure of the device of the present invention is relatively simple, and the various parts of the structure are easy to replace. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] The inventor's research found that for patients with mental illness or those with physical diseases, they may engage in self-harm behaviors including biting their tongue when the disease occurs. The reason for this behavior may be due to the patient's subjective consciousness or because the patient suffers from diseases such as epilepsy. This behavior may not only cause tongue injury to the patient, but may even be life-threatening in severe cases. At present, some products have appeared to prevent patients from biting their tongues. However, these products have many problems, such as being cumbersome to use and only preventing tongue biting by fixing the mouth to support it, which makes the patient feel uncomfortable when using it and the anxiety cannot be relieved to a certain extent. At the same time, the existing anti-tongue bite products have a complex structure and are not easy to wear and use.

[0023] Based on the above findings, the present application proposes a protective device for preventing tongue bite in the department of psychiatry and psychology, designs an anti-bite component, designs a support part on the tooth sleeve that allows the patient to bite to a certain extent, and nests a memory alloy wire and a support ring on the tooth sleeve to form an adaptive support mechanism, which performs adaptive support when the patient bites the tooth sleeve, and arranges support airbags and side airbags on both sides of the tooth sleeve to form a pneumatic support mechanism. When the tooth sleeve is bent and closed, gas is input into the support airbags through the side airbags to support both sides of the tooth sleeve through the support airbags, and a tongue depressor that can press the patient's tongue back into the oral cavity when the tooth sleeve is bent, and presses the patient's tongue back into the oral cavity through the tongue depressors located on the upper and lower sides of the tooth sleeve to prevent the patient from biting the tongue when the disease occurs; it has the advantages of good safety, easy use, high comfort and simple structure.

[0024] See also Figure 1-Figure 3 The present application discloses a protective device for preventing tongue bite in the psychiatric department, including a tooth sleeve 1. The overall shape of the tooth sleeve 1 is relatively close to the periodontal shape of an average adult. In some embodiments of the present invention, the overall material of the tooth sleeve 1 can be selected as a plastic material with good elasticity. At the same time, the tooth sleeve 1 can be roughly divided into an upper and lower part with a curved connecting section in the middle. The tooth sleeve 1 maintains a naturally open state under normal conditions. When wearing the tooth sleeve 1, the psychiatric patient can choose to place the teeth and lips as a whole in the grooves of the upper and lower parts of the tooth sleeve 1, or only place the teeth in the grooves and let the lips cover the tooth sleeve 1.

[0025] The tooth sleeve 1 is provided with connecting plates 2 on both sides. In one embodiment of the present invention, the connecting plates 2 are connected and fixed to the tooth sleeve 1 through the supporting portion 41 in the anti-bite component 4. The connecting plates 2 are plate structures with a cavity in the middle. The material of the connecting plates 2 can be selected from plastics with high strength. Fig.10 The ends of the two side connecting plates 2 away from the tooth sleeve 1 are rotatably connected with a strap 3, and the two straps 3 are fixed by setting a lock buckle 6 structure at the farthest end, so that the entire device can be worn on the patient's head, and the connecting plate 2 can fit to both sides of the patient's cheeks when worn.

[0026] The tooth sleeve 1 is provided with an anti-bite component 4 for preventing psychiatric patients from biting their tongues, wherein the anti-bite component 4 can be roughly divided into a supporting portion 41 and a tongue depressing portion 42 in terms of structure. The supporting portion 41 can allow the patient to bite the tooth sleeve 1 to a certain extent when the patient is ill, and then support and fix the tooth sleeve 1 to leave a breathing gap in the patient's mouth to avoid suffocation of the patient. The tongue depressing portion 42 can retract the patient's tongue that is stretched out of the mouth or placed on the teeth into the mouth when the tooth sleeve 1 is bitten, so as to prevent the patient from biting the tongue.

[0027] The support portion 41 includes an adaptive support mechanism 410, see Figure 4 , Fig.12 as well as Fig.13 The adaptive support mechanism 410 includes a support ring 4101 and a memory alloy wire 4102 nested on the gear sleeve 1, wherein the support ring 4101 is made of D3O material, which is an impact-resistant material composed of "intelligent molecules". These molecules remain relaxed, soft and elastic under normal conditions; however, once the D3O material is subjected to severe impact or extrusion, the molecules will quickly lock, the material will tighten and harden, thereby absorbing the external force and forming a protective layer. When the external force disappears, the material will return to its original relaxed soft elastic state. This material can react to different impact conditions within nanoseconds; the overall shape of the support ring 4101 is similar to the tooth sleeve, except that the connection ends of the upper and lower parts thereof are vertical structures. In some embodiments, the support ring 4101 is located between the upper and lower parts of the tooth sleeve 1, and the upper and lower parts of the support sleeve box 4101 are respectively fixed to the upper and lower parts of the tooth sleeve 1 by bonding or other means. When a psychiatric patient becomes ill and bites the tooth sleeve 1, the support ring 4101 can limit the patient's initial strong bite and support the tooth sleeve 1; In some embodiments of the present invention, groove structures for embedding the memory alloy wire 4102 are provided on the end surfaces of the upper and lower parts of the tooth sleeve 1. The initial state of the memory alloy wire 4102 can keep the tooth sleeve 1 in an open state. When the patient bites the tooth sleeve 1, the memory alloy wire 4102 can provide a certain support effect for the tooth sleeve 1. At the same time, when the patient stops biting and opens the mouth, the auxiliary tooth sleeve 1 can be restored to the initial open state as a whole.

[0028] The support portion 41 further includes a pneumatic support mechanism 411, see Figure 5-Figure 8 The pneumatic support mechanism 411 includes a support airbag 4111 fixed on both sides of the gear sleeve 1 and located above the lower part. In some embodiments, the airbag 4111 is a flat rectangular structure as a whole, and a groove matching the support ring 4101 is provided at the bottom. During installation, the bottom of the airbag 4111 can be bonded and fixed to the support ring 4101 through the groove; A side airbag 4112 is provided in the inner cavity of the connecting plate 2 located on both sides of the gear sleeve 1. The side airbag 4112 is connected to the support airbag 4111 by means of an air delivery pipe 4113. At the same time, a fixing plug 4115 is provided at the curved connection between the upper and lower parts of the gear sleeve 1 by bonding or the like. The shape of the fixing plug 4115 is close to a semi-cylindrical structure, and its curved surface matches the curved connection of the gear sleeve 1. A transverse fixing groove is provided on its plane end. In some embodiments, a connection block 4116 is inserted and fixed in the fixing groove of the fixing plug 4115. The connection block 4116 is a two-section structure, one end of which is a flat rectangular plate structure with a through hole in the middle, and the other end is a slender rod structure. One side of the plate end of the connection block 4116 is inserted into the fixing groove on the fixing plug 4115, and at the same time, the through hole in the middle is sleeved and fixed at the connection between the upper and lower parts of the support collar 4101. When the patient continues to bite the tooth sleeve 1, the support collar 4101 can drive the plate end of the connection block 4116 to move downward; In some embodiments, a threaded rod is provided at the rod end of the connection block 4116. During installation, the threaded rod is inserted into the through hole provided on the connection plate 2, and a concealed bolt 4117 is screwed in to fix the connection block 4116 to the connection plate 2. In some embodiments, a through hole is provided inside the connection block 4116 for the air delivery pipe 4113 to pass through, and the air delivery pipe 4113 runs through the connection block 4116, one end of the air delivery pipe passes through the through hole provided on the connection plate 2 and communicates with the side airbag 4112, and the other end passes vertically downward along the plate end of the connection block 4116 and communicates with the support airbag 4111. In addition, a control device capable of controlling the air delivery pipe 4113 is provided below the plate end of the connection block 4116 and on the air delivery pipe 4113. The gas valve 4114 in the gas flow direction and the gas pipe 4113 are made of a plastic material with a certain elasticity. When the plate end of the connecting block 4116 moves downward under the action of the supporting collar 4101, it can move downward along the gas pipe 4113, thereby triggering the gas valve 4114, so that the gas in the side airbag 4112 is input into the supporting airbag 4111. The gas valve 4114 is a common two-way gas valve product. When implementing the invention, a product that can achieve the purpose of the invention can be selected, and its model is not described in detail here.

[0029] It should be noted that, for the adaptive support mechanism 410, when the patient first uses a strong bite force to bite the tooth sleeve 1, the support ring 4101 immediately restricts the closure of the tooth sleeve 1, and then the bite force gradually weakens, the support ring 4101 gradually closes, and drives the support airbag 4111 in the pneumatic support mechanism 411 to inflate and prop up. During this period, the support of the support ring 4101 and the memory alloy wire 4102 can support the tooth sleeve 1 to a certain extent, thereby providing sufficient time for the inflation of the support airbag 4111, and finally supporting and fixing the tooth sleeve 1.

[0030] The tongue depressor 42 includes a first tongue depressor 4201 fixed at the lower part of the upper part of the tooth sleeve 1 and a second tongue depressor 4202 fixed at the upper part of the lower part of the tooth sleeve 1. In some embodiments, the first tongue depressor 4201 and the second tongue depressor 4202 are both plate structures with a shape close to a fan. When installed, they can be fixed to the tooth sleeve 1 by means of clamping or bonding, and are located outside the supporting collar 4101. There is a certain inclination angle between the first tongue depressor 4201 and the upper part of the tooth sleeve 1 during installation, and the overall length of the first tongue depressor 4201 is greater than that of the second tongue depressor 4202, so that when the tooth sleeve 1 is gradually closed, during the downward movement of the first tongue depressor 4201, its lowermost end can contact the middle part of the patient's tongue, and then press the patient's tongue into the oral cavity, that is, press it below the plane where the second tongue depressor 4202 is located, so that the patient's tongue can be pressed back regardless of whether it is extended outside the oral cavity or located above the second tongue depressor 4202, so as to prevent the patient from biting his tongue.

[0031] In some embodiments, the device as a whole further comprises a pry plate 5, which is a plate structure with a cylindrical handle at one end, and can be inserted into the patient's oral cavity in special circumstances to pry open the tooth sleeve 1. A threaded groove is provided at the cylindrical handle end of the pry plate 5, and a wrench 501 is threadedly connected in the threaded groove. One end of the wrench 501 is a hollow cylindrical structure, and a toothed structure matching the outer surface of the concealed bolt 4117 is provided inside the cylindrical structure. When the concealed bolt 4117 fixes the connecting plate 2 and the connecting block 4116, its outer end face is located inside the end face of the connecting plate 2, which can prevent the patient from feeling anxious due to the onset of the disease and thus dismantling the connecting plate 2 and the connecting block 4116 by himself. When dismantling is required, the wrench 501 can be used to insert along the through hole on the connecting plate 2, and the concealed bolt 4117 can be screwed out to dismantle the connecting plate 2 and the connecting block 4116. In addition, the threaded groove at the handle end of the cylinder of the pry plate 5 also extends inward to form a hollow chamber as a storage chamber 502. The storage chamber 502 can be used to store medicines for emergency treatment. When the patient encounters an accident, the medicines can be taken from the storage chamber 502.

[0032] A method for using a protective device for preventing tongue bite in a psychiatric department comprises the following steps: S1, fit the tooth cover 1 to the patient's teeth, and use the strap 3 to fix the protective device as a whole to the patient's head; S2. When the patient bites the tooth sleeve due to an illness, the support ring 4101 and the memory alloy wire 4102 in the adaptive support mechanism 410 limit the closing of the tooth sleeve 1, providing sufficient time for the pneumatic support mechanism 411, and the side airbag 4112 in the pneumatic support mechanism 411 inflates the support airbag 4111 to prevent the tooth sleeve 1 from closing. When the tooth sleeve 1 is closed, the tongue is pressed back into the oral cavity by the first tongue depressor 4102 to prevent the patient from biting the tongue; S3. When the device cannot be opened by itself due to a malfunction, the concealed bolt 4117 is removed using a wrench 501, and the tooth sleeve 1 is opened by the pry plate 5 to open the patient's mouth.

[0033] Practical application cases

[0034] In the treatment of psychiatric psychology, whether the device needs to be used is determined based on the patient's psychological state and medical history. When it is determined that the patient is at risk of biting the tongue due to illness or emotional reasons, the device can be worn on the patient's head. When wearing it, the patient's teeth fit the tooth sleeve 1, and the connecting plate 2 is placed on both sides of the cheek, and then the strap 3 and the buckle 6 are used to fix the entire device to the patient's head; When the patient has a tendency to bite his tongue due to illness or anxiety, the patient first bites the tooth sleeve 1. At this time, the support ring 4101 hardens quickly to prevent the patient from biting the tooth sleeve 1 with the strongest force. When the patient's bite force gradually weakens, the tooth sleeve 1 gradually closes. During the closing period, the pneumatic support mechanism 411 is activated, and the support airbag 4111 on the tooth sleeve 1 is inflated to support the upper and lower parts of the tooth sleeve 1 to prevent it from being completely closed. When the tooth sleeve 1 is gradually closed, the first tongue depressor 4201 rotates downward to contact and press down the middle part of the patient's tongue. When the tooth sleeve 1 continues to close, the first tongue depressor 4201 can press the patient's tongue back into the oral cavity. When the patient stops biting and slowly opens his mouth, the tooth sleeve 1 gradually opens under the resetting action of the supporting ring 4101 and the memory alloy wire 4102, so that the whole device is gradually reset; When the gear sleeve 1 cannot be opened, the pry plate 5 can be used to open the gear sleeve 1, or the concealed bolt 4117 on the connecting plate 2 can be screwed out using a wrench 501 to disassemble the device.
