Description

Technical Field

[0001] This invention relates to the technical field of medical devices, and more particularly to a disinfection and purification device for the oral cavity and upper respiratory tract. Background Technology

[0002] In the field of healthcare, especially in the control and prevention of infections of the oral cavity and upper respiratory tract, traditional methods such as drug therapy and physical therapy have certain limitations. For example, drug therapy may be accompanied by side effects or drug resistance, while some physical therapies may be inconvenient to use widely due to their complexity or limited applicability. With increasing public awareness of health and growing demand for non-invasive and efficient treatment methods, exploring new, non-invasive disinfection and purification technologies has become a trend.

[0003] Ozone (O3), as a potent natural oxidant, exhibits unique advantages in sterilization and disinfection. It possesses broad-spectrum bactericidal capabilities, rapidly killing a variety of pathogenic microorganisms, and currently there is no evidence that microorganisms develop resistance to it; furthermore, it decomposes to produce only oxygen, leaving no harmful residues. Therefore, by precisely controlling the ozone concentration, it can be used for disinfection and purification of the oral cavity and upper respiratory tract. However, there is currently a lack of dedicated medical devices for these areas, necessitating further research and development of safe and effective targeted delivery technologies. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an oral cavity and upper respiratory tract disinfection and purification device, which solves the technical problem of the lack of a targeted device for targeted disinfection and purification of the patient's oral cavity and upper respiratory tract in the prior art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] In a first aspect, the present invention provides an oral cavity and upper respiratory tract disinfection and purification device, comprising an occlusal member, an oral cavity tube, a nasal cavity tube, and an ozone supply device. The input ends of the articulated frame oral cavity tube and the nasal cavity tube are both selectively connected to the articulated frame ozone supply device to output ozone. A first channel is formed in the middle of the articulated frame occlusal member, and an occlusal portion suitable for patient biting is formed on the outer periphery of the articulated frame occlusal member. The articulated frame oral cavity tube is supported within the first channel of the articulated frame, and one end is a first output end. When the patient bites the occlusal portion of the articulated frame, the articulated frame... The first output end extends into the patient's oral cavity via the articulated frame; the articulated frame nasal tube includes a U-shaped tube, the two ends of which are two second output ends; the articulated frame U-shaped tube is hinged to the articulated frame engagement member along the transverse axis with a limited position, and can swing and switch between the used position and the idle position; in the used position of the articulated frame, the two second output ends of the articulated frame swing upward to the position of the corresponding nostril of the patient; in the idle position of the articulated frame, the two second output ends of the articulated frame swing downward to the position away from the nostril of the patient.

[0009] In one technical solution of the present invention, the oral cavity and upper respiratory tract disinfection and purification device further includes a three-way valve. The three-way valve of the hinge frame is supported on the oral cavity tube of the hinge frame, and the three ports are respectively connected to the input end of the oral cavity tube, the input end of the nasal cavity tube, and the ozone supply device. The three-way valve of the hinge frame can switch to the oral cavity output state of the first output end outputting gas, the nasal cavity output state of the second output end outputting gas, or the dual output state of the first output end and the second output end of the hinge frame simultaneously outputting gas.

[0010] In one technical solution of the present invention, the articulated frame oral tube is axially limited and slidably connected within the first channel of the articulated frame to adjust the output position of the first output end of the articulated frame in the patient's oral cavity.

[0011] In one technical solution of the present invention, a sleeve is fixedly connected to the articulated frame occlusal member, the articulated frame oral tube has a limiting part, and the articulated frame oral tube is axially slidably connected inside the articulated frame sleeve; when the limiting part of the articulated frame abuts against the end of the articulated frame sleeve, it is the longest length of the articulated frame oral tube extending into the patient's oral cavity.

[0012] In one technical solution of the present invention, the U-shaped tube of the hinge frame includes a horizontally extending section and two vertical sections that are axially sealed and slidably connected to both ends of the horizontal section of the hinge frame and extend vertically. The middle part of the horizontal section of the hinge frame is hinged to the hinge frame engagement member. The upper outlet ends of the two vertical sections of the hinge frame form the second output end of the hinge frame. The two vertical sections of the hinge frame can move closer to or further away from the horizontal section of the hinge frame simultaneously to adjust the output height of the second output end of the two hinge frames.

[0013] In one technical solution of the present invention, the articulated frame nasal tube further includes a support section and a rotating tube that extend vertically. The lower part of the rotating tube is axially rotatably connected to the middle part of the horizontal section of the articulated frame. The support section is threadedly connected to the upper part of the rotating tube. The second output ends of the two articulated frames are both supported on the support section. The vertical section of the articulated frame includes a fixed section and a sliding section. The fixed section is connected to the horizontal section. The sliding section is axially and slidably connected to the upper end of the fixed section. The upper end of the sliding section forms the second output end of the articulated frame. When the rotating tube is rotated, the support section can synchronously drive the two sliding sections of the articulated frames to rise and fall, thereby adjusting the output height of the second output ends of the two articulated frames.

[0014] In one technical solution of the present invention, a spacing adjustment component is also included; the hinge frame spacing adjustment component includes a gear, a knob and two racks, a gear cavity is formed in the hinge frame support section, the hinge frame gear is rotatably connected in the hinge frame gear cavity, the hinge frame knob is fixedly connected to the hinge frame gear and located outside the hinge frame gear cavity; one end of each of the two hinge frame racks is fixedly connected to the corresponding hinge frame sliding section, and the other end of each rack penetrates through the side wall of the hinge frame gear cavity and meshes with the upper and lower sides of the hinge frame gear respectively, so that the two hinge frame racks form a support component between the hinge frame support section and the hinge frame vertical section.

[0015] In one technical solution of the present invention, a hinge frame is fixedly connected to the horizontal section of the hinge frame. The horizontal section of the hinge frame is hinged to the hinge frame engagement member through the hinge frame hinge frame. The hinge frame extends forward so that the U-shaped tube of the hinge frame can extend forward to form a relief area for the patient's upper lip.

[0016] In one embodiment of the present invention, the articulated frame nasal cavity tube further includes a flexible contact layer sleeved on the second output end of the articulated frame.

[0017] In one embodiment of the present invention, the articulated frame superoxide supply device is a portable superoxide generator.

[0018] (III) Beneficial Effects

[0019] The beneficial effects of this invention are as follows: The oral cavity and upper respiratory tract disinfection and purification device of this invention, by organically combining a biting component, an oral cavity tube, a nasal cavity tube, and an ozone supply device, achieves a convenient and comprehensive disinfection method. The biting component has a first channel in its center, and its periphery is designed with a biting portion for the patient to bite on. This biting portion not only fixes the position of the device but also keeps the mouth open when the patient bites, facilitating the stable delivery of ozone into the oral cavity by the oral cavity tube. The oral cavity tube is supported within the first channel, with one end serving as the first output end, which can extend deep into the oral cavity when the patient bites on, thereby achieving efficient coverage and continuous disinfection of the oral cavity space.

[0020] The nasal cannula features a U-shaped structure with two secondary outputs at each end, corresponding to the patient's two nostrils. The U-shaped tube is hinged to the bite plate via a transverse axis, allowing for flexible switching between a used and idle position. In the used position, the two secondary outputs swing upwards to align with the nostrils, precisely delivering ozone into the nasal cavity and upper respiratory tract for purification. In the idle position, the secondary outputs swing downwards away from the nostrils to avoid interfering with the patient's breathing or movement, and also facilitate storage and cleaning of the device.

[0021] Both the oral and nasal tubes can be selectively connected to an ozone supply device, allowing users to choose between oral or nasal disinfection alone, or simultaneous dual-channel disinfection, thus improving treatment flexibility and adaptability. This multi-mode switching not only enhances the device's practicality but also improves the personalization of treatment.

[0022] Through its integrated design, the device achieves disinfection of both the oral cavity and upper respiratory tract, improving treatment efficiency. The occlusal design not only helps secure the device but also effectively prevents tube compression or displacement caused by oral closure, ensuring stability during treatment. The nasal tube's swingable structure allows it to be retracted when not in use, reducing space occupation and enhancing ease of use. Simultaneously, ozone, as a potent natural oxidant, possesses broad-spectrum bactericidal capabilities, rapidly killing various pathogenic microorganisms without residue or drug resistance, making it suitable for the prevention and adjunctive treatment of various oral and upper respiratory tract infections. Therefore, this device has significant potential for widespread clinical application and promising practical prospects. Attached Figure Description

[0035] To better explain and facilitate understanding of this invention, the following description is provided in conjunction with the appendix. Figures 1-3 The present invention will be described in detail through specific embodiments. In this document, directional terms such as "upper" and "lower" are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0036] Example 1:

[0037] Reference Figures 1-3 This invention provides an oral cavity and upper respiratory tract disinfection and purification device, including a bite member 1, an oral cavity tube 2, a nasal cavity tube 3, and an oxygen supply device. The input ends of the oral cavity tube 2 and the nasal cavity tube 3 can be selectively connected to the oxygen supply device to output oxygen. A first channel is formed in the middle of the bite member 1, and an occlusal portion 1b suitable for the patient's bite is formed on the outer periphery of the bite member 1. The oral cavity tube 2 is supported in the first channel, and one end is a first output end 2a. When the patient bites the occlusal portion 1b, the first output end 2a extends into the patient's oral cavity. The nasal cavity tube 3 includes a U-shaped tube 31, and the two ends of the U-shaped tube 31 are two second output ends 31a. The U-shaped tube 31 is hinged to the bite member 1 with a limit along the transverse axis and can swing and switch between a used position and an idle position. In the used position, the two second output ends 31a swing upward to the position corresponding to the patient's nostrils. In the idle position, the two second output ends 31a swing downward to a position away from the patient's nostrils.

[0038] In this embodiment, the oral cavity and upper respiratory tract disinfection and purification device organically combines the bite member 1, oral cavity tube 2, nasal cavity tube 3, and ozone supply device to achieve a convenient and comprehensive disinfection method. The bite member 1 has a first channel in its center and a bite portion 1b around its periphery for the patient to bite on. This bite portion 1b not only fixes the device's position but also keeps the patient's mouth open when biting, facilitating the stable delivery of ozone into the oral cavity by the oral cavity tube 2. The oral cavity tube 2 is supported within the first channel, with one end serving as the first output end 2a, which extends deep into the oral cavity when the patient is biting, thereby achieving efficient coverage and continuous disinfection of the oral cavity space.

[0039] The nasal tube 3 adopts a U-shaped tube 31 structure, with two ends serving as second output ends 31a, corresponding to the patient's two nostrils respectively. The U-shaped tube 31 is hinged to the bite member 1 via a transverse axis, allowing for flexible switching between a used position and an idle position. When in the used position, the two second output ends 31a swing upwards to align with the nostrils, thereby precisely introducing ozone into the nasal cavity and its upper respiratory tract area to purify the nasal cavity. When in the idle position, the second output ends 31a swing downwards, away from the nostrils, to avoid interfering with the patient's normal breathing or movement, and also to facilitate the storage and cleaning of the device.

[0040] Both the oral cavity fitting 2 and the nasal cavity fitting 3 can be selectively connected to an ozone supply device, allowing users to choose to use oral or nasal disinfection alone, or to perform dual-channel disinfection simultaneously, thereby improving the flexibility and adaptability of treatment. This multi-mode switching not only enhances the practicality of the device but also improves the personalization of treatment.

[0041] Through its integrated design, the device achieves disinfection of both the oral cavity and upper respiratory tract, improving treatment efficiency. The design of the occlusal component 1 not only helps to fix the device in place but also effectively prevents tube compression or displacement caused by oral closure, ensuring the stability of the treatment process. The swingable structure of the nasal tube component 3 allows it to be retracted when not in use, reducing space occupation and improving ease of use. Meanwhile, ozone, as a powerful natural oxidant, has broad-spectrum bactericidal capabilities, rapidly killing various pathogenic microorganisms without residue or drug resistance, making it suitable for the prevention and adjunctive treatment of various oral and upper respiratory tract infections. Therefore, this device has good promotional value and practical prospects in clinical application.

[0042] Specifically, the concentration of superoxide should be controlled within a safe range to avoid excessive stimulation of the patient's anterior membrane and causing discomfort.

[0043] The shape of the occlusal part 1b should match the shape of the patient's upper and lower teeth, and the occlusal part 1b should have a groove of a certain depth to assist in the positioning of the occlusal part 1b. The occlusal component 1, oral cavity component 2, and nasal cavity component 3 can be a set for individual use, and should be thoroughly sterilized after each use to avoid infection, or they can be set as disposable components to improve ease of use and further avoid secondary infection.

[0044] The main structure of the bite component 1, oral cavity component 2, and nasal cavity component 3 can be made of medical-grade plastic.

[0045] The hinged connection between the U-shaped tube 31 and the interlocking member 1 must have a certain amount of damping, at least enough to keep the U-shaped tube 31 in the working position.

[0046] Example 2:

[0047] Reference Figures 1-3 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0048] It also includes a three-way valve 4, which is supported on the oral cavity fitting 2, and its three ports are respectively connected to the input end of the oral cavity fitting 2, the input end of the nasal cavity fitting 3, and the ozone supply device.

[0049] The three-way valve 4 can switch to the oral cavity output state of the first output end 2a, the nasal cavity output state of the second output end 31a, or the dual output state of the first output end 2a and the second output end 31a simultaneously outputting gas.

[0050] In this embodiment, different gas delivery modes can be selected by adjusting the working state of the three-way valve 4. Specifically, the three-way valve 4 can be switched to an oral output mode where only the oral cavity fitting 2 outputs ozone, a nasal output mode where only the nasal cavity fitting 3 outputs ozone, and a dual output mode where ozone is output from both the oral cavity and nasal cavity simultaneously. This not only enhances the functional versatility of the device but also strengthens its adaptability in different clinical scenarios. For example, when only local disinfection of the oral cavity is required, the oral output mode can be selected to avoid unnecessary irritation to the nasal cavity; when treating upper respiratory tract infections or nasal inflammation, the nasal output mode can be switched to achieve precise treatment; for situations requiring comprehensive purification of the oral cavity and upper respiratory tract, such as preoperative preparation or environments with high infection risk, the dual output mode can be activated to achieve simultaneous disinfection of multiple sites and improve treatment effectiveness.

[0051] Specifically, the three-way valve 4 can be fixedly connected to the end of the oral cavity tube 2 away from the oral cavity, so as to indirectly support the occlusal member 1. The three-way valve 4 establishes a connection with the nasal cavity tube 3 through a flexible tube, ensuring the overall structural compactness of the device.

[0052] More specifically, the three-way valve 4 has a T-shaped channel inside, namely a T-shaped three-way ball valve, which can meet the flow requirements of superoxide gas in this embodiment.

[0053] Example 3:

[0054] Reference Figures 1-3 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0055] The oral tube 2 is axially limited and slidably connected within the first channel to adjust the output position of the first output end 2a in the patient's oral cavity.

[0056] The occlusal member 1 is fixedly connected to the sleeve 1c, and the oral tube 2 has a limiting part 2b. The oral tube 2 is axially slidably connected inside the sleeve 1c. When the limiting part 2b abuts against the end of the sleeve 1c, it is the longest length of the oral tube 2 extending into the patient's oral cavity.

[0057] In this embodiment, the first output terminal 2a can be positioned according to the depth of the area requiring treatment within the patient's oral cavity, ensuring that the superoxide gas is precisely delivered to the target area within the oral cavity. This structure not only improves the device's personalized adaptability but also enhances the targetedness and effectiveness of the treatment.

[0058] The limiting part 2b slides together with the oral cavity fitting 2 within the sleeve 1c, and abuts against the end of the sleeve 1c when it slides to it, thereby limiting the oral cavity fitting 2 from extending further into the oral cavity and preventing discomfort or damage caused by excessive insertion. While ensuring safe use, it also allows medical staff or patients to quickly adjust the position of the output end according to the actual situation.

[0059] Specifically, the limiting part 2b can be the end of the three-way valve 4, that is, the end of the three-way valve 4 is used to limit the sliding position of the oral cavity tube 2.

[0060] Example 4:

[0061] Reference Figures 1-3 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0062] The U-shaped tube 31 includes a horizontally extending section 311 and two vertical sections 312 that are axially sealed and slidably connected to both ends of the horizontal section 311 and extend vertically. The middle part of the horizontal section 311 is hinged to the engagement member 1. The upper outlet ends of the two vertical sections 312 form second output ends 31a. The two vertical sections 312 can move closer to or further away from the horizontal section 311 simultaneously to adjust the output height of the two second output ends 31a.

[0063] In this embodiment, the U-shaped tube 31 includes a horizontally extending section 311 and two vertically extending sections 312 connected to both ends of the horizontal section 311, respectively. The upper ends of the two vertical sections 312 serve as second output ends 31a, corresponding to the patient's two nostrils respectively. The middle part of the horizontal section 311 is hinged to the bite member 1, allowing the entire U-shaped tube 31 to swing and switch between a used position and an idle position, facilitating operation and storage.

[0064] The two vertical segments 312 can move closer to or further away from the horizontal segment 311 simultaneously, thereby adjusting the height of the two second output ends 31a. This structural design allows the output ends to flexibly adapt to different patients' facial heights and nostril positions, ensuring that the superoxide gas can be accurately delivered to the nasal cavity entrance, improving the precision and comfort of treatment. For example, for patients with higher facial features or higher nostril positions, the height of the second output ends 31a can be increased by moving the two vertical segments 312 away from the horizontal segment 311; while for patients with flatter facial features or lower nostril positions, the vertical segments 312 can be moved closer to the horizontal segment 311 to lower the height of the output ends, thus achieving personalized adaptation.

[0065] This adjustable structure not only enhances the device's adaptability but also effectively avoids gas leakage or reduced delivery efficiency caused by mismatched output positions. By synchronously adjusting the relative positions of the two vertical sections 312, good symmetry between the two output ends can be ensured, further improving the user experience and treatment effectiveness.

[0066] In summary, the combination of the height adjustment function and the swing switching function of the U-shaped tube 31 makes the nasal tube 3 more flexible and reliable in use, maintaining good adaptability and functionality in different application scenarios. Combined with the axial adjustment structure of the oral tube 2 and the multi-mode switching function of the three-way valve 4, this oral cavity and upper respiratory tract disinfection and purification device achieves comprehensive, personalized, and efficient disinfection of the oral cavity and upper respiratory tract, showing promising clinical application prospects.

[0067] Example 5:

[0068] Reference Figures 1-3 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0069] The nasal tube 3 also includes a vertically extending support section 313 and a rotating tube 314. The lower part of the rotating tube 314 is axially rotatably connected to the middle part of the horizontal section 311, and the support section 313 is threadedly connected to the upper part of the rotating tube 314. Both second output ends 31a are supported on the support section 313. The vertical section 312 includes a fixed section 3121 and a sliding section 3122. The fixed section 3121 is connected to the horizontal section 311, and the sliding section 3122 is axially and slidably connected to the upper end of the fixed section 3121. The upper end of the sliding section 3122 forms the second output end 31a. When the rotating tube 314 is rotated, the support section 313 can synchronously drive the two sliding sections 3122 to rise and fall, so as to adjust the output height of the two second output ends 31a.

[0070] The lower part of the rotating tube 314 is mounted in the middle of the horizontal section 311 via an axial rotational connection, ensuring that it can rotate smoothly around the central axis of the horizontal section 311 while remaining axially fixed to avoid unnecessary axial displacement. The support section 313 is connected to the upper part of the rotating tube 314 via a threaded connection, allowing the support section 313 to move axially up and down as the rotating tube 314 rotates. Both second output ends 31a are supported on the support section 313, so that the up and down movement of the support section 313 can directly drive the two second output ends 31a to synchronously adjust their vertical height.

[0071] Furthermore, the sliding section 3122 is nested within the upper end of the fixed section 3121 in an axially sealed sliding manner. This sealed sliding connection not only ensures the sealing of gas or fluid during transmission within the vertical section 312, preventing leakage, but also allows the sliding section 3122 to move smoothly up and down relative to the fixed section 3121. The upper end of the sliding section 3122 is the second output end 31a, therefore, changes in its position directly determine the height of the output port.

[0072] When the user rotates the rotating tube 314, the rotation of the tube 314 is converted into axial displacement of the support section 313 due to the threaded connection between the support section 313 and the rotating tube 314. This displacement, in turn, causes the two sliding sections 3122 supported on the support section to rise or fall synchronously. This linkage mechanism enables precise and synchronous adjustment of the height of the two second output ends 31a. Because the movement of the two sliding sections 3122 is completely synchronized, it effectively ensures that the height of the two output ends remains consistent during the height adjustment process, avoiding discomfort or connection problems caused by height deviation.

[0073] First, height adjustment is achieved through the threaded engagement of the rotating tube 314 and the support section 313. This method is simple to operate and offers high adjustment precision. Users only need to rotate the rotating tube 314 to set the height, without the need for complicated tools or procedures. Second, the support section 313 simultaneously supports two sliding sections 3122, ensuring synchronous lifting and lowering of the output ends on both sides. This improves the symmetry and stability of the adjustment and avoids structural imbalance that may be caused by unilateral adjustment. Furthermore, the axially sealed sliding connection between the sliding section 3122 and the fixed section 3121 ensures the sealing performance of the gas passage while achieving the height adjustment function, thereby enhancing the safety and reliability of the equipment.

[0074] This device can first improve the precision and comfort of treatment by adjusting the structure in multiple dimensions to suit the anatomical features of different patients; secondly, it can enhance the convenience and safety of operation, avoiding problems caused by structural misalignment or gas leakage, and has good clinical promotion value and market application prospects.

[0075] Example 6:

[0076] Reference Figures 1-3 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0077] It also includes a pitch adjustment component 5; the pitch adjustment component 5 includes a gear 51, a knob 52 and two racks 53, a gear 51 cavity is formed in the support section 313, the gear 51 is rotatably connected in the gear 51 cavity, the knob 52 is fixedly connected to the gear 51 and located outside the gear 51 cavity; one end of each of the two racks 53 is fixedly connected to the corresponding output end, and the other end of each rack passes through the side wall of the gear 51 cavity and meshes with the upper and lower sides of the gear 51 respectively, so that the two racks 53 form a support between the support section 313 and the vertical section 312.

[0078] In this embodiment, the device introduces a combination structure of a second sliding sleeve and a spacing adjustment component 5 in the horizontal section 311 of the nasal cavity tube 3, so that the lateral spacing between the output ends is adjustable, thereby more accurately matching the nostril spacing of different patients and enhancing the adaptability and comfort of use.

[0079] The second sliding sleeve has good extensibility and sealing performance, which not only maintains the continuity of the air passage, but also allows relative movement between the first section, the support section 313, and the third section within a certain range, thereby realizing the elastic adjustment of the overall lateral structure of the nasal cavity fitting 3. This flexible connection method provides a structural basis for subsequent spacing adjustment, while ensuring the continuity and stability of gas delivery.

[0080] A gear cavity 51 is provided inside the support section 313, in which a gear 51 is rotatably connected. The center of the gear 51 is fixedly connected to a knob 52, which is located outside the gear cavity 51 for easy user operation. Two racks 53 are respectively arranged on both sides of the gear 51, with one end fixedly connected to the corresponding vertical section 312, and the other end passing through the side wall of the gear cavity 51 and meshing with the upper and lower sides of the gear 51. When the user rotates the knob 52, the gear 51 rotates synchronously, thereby driving the two racks 53 to move in opposite directions, thus realizing the adjustment of the lateral distance between the two vertical sections 312.

[0081] The spacing adjustment component 5 has a clever structural design. Through the linkage mechanism of gear 51 and rack 53, it realizes the synchronous and symmetrical adjustment of the two output ends, ensuring that the output ends are always in a symmetrical position, and avoiding discomfort or uneven gas delivery caused by misalignment.

[0082] Furthermore, the rack 53 not only serves as a transmission component but also as a support component for the vertical section 312, achieving multiple uses and further improving the structural compactness of the device.

[0083] In summary, by introducing the second sliding sleeve and the spacing adjustment component 5, the nasal cavity fitting 3 achieves flexible adjustment of the lateral spacing, further enhancing the applicability and practicality of the device in clinical applications. Combined with the axial adjustment function of the oral cavity fitting 2, the multi-mode switching function of the three-way valve 4, and the stable support of the occlusal component 1, the entire oral cavity and upper respiratory tract disinfection and purification device forms a personalized, safe, and reliable treatment system suitable for various clinical scenarios, such as pre- and post-operative disinfection of the oral cavity, upper respiratory tract infection control, adjunctive treatment of respiratory diseases, and preventative use in high-risk infection environments. It has significant clinical promotion value and broad application prospects.

[0084] Specifically, the axis of gear 51 can be set perpendicular to the patient's facial plane, and the rack 53 can be set with a special shape, for example, on a long strip of medical plastic, teeth are formed in the middle and slide bars are formed on both sides of the teeth. In this way, gear 51 engages with the teeth, and the slide bars can slide with the side wall of the gear 51 cavity, thereby achieving the requirement of supporting the vertical section 312 while maintaining the sliding engagement relationship between rack 53 and the side wall of gear 51 cavity.

[0085] Example 7:

[0086] Reference Figures 1-3 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0087] A hinge frame 6 is fixedly connected to the horizontal segment 311. The horizontal segment 311 is hinged to the occlusal member 1 through the hinge frame 6. The hinge frame 6 extends forward so that the U-shaped tube can extend forward to form a relief area for the patient's upper lip.

[0088] In this embodiment, a forward-extending hinge frame 6 is added to the horizontal section 311 of the device, so that the U-shaped tube 31 is hinged to the bite member 1 through the hinge frame 6. This not only enhances the stability of the U-shaped tube 31 swinging between the use position and the idle position, but more importantly, the forward extension structure of the hinge frame 6 provides a more reasonable spatial guide for the overall layout of the U-shaped tube 31, so that the U-shaped tube 31 can extend forward when it swings to the use position, thereby forming an upper lip relief area in the patient's facial area.

[0089] The design of the upper lip clearance area fully considers the characteristics of the human facial structure. Especially when the nasal tube 3 is in use, the forward extension of the U-shaped tube 31 naturally avoids the patient's upper lip area, preventing pressure or discomfort caused by contact between the tube and the upper lip, thus improving wearing comfort. At the same time, this forward clearance structure also helps maintain the alignment stability between the output end of the nasal tube 3 and the nostril, preventing tube displacement caused by slight patient movements or facial muscle movements, thereby ensuring that the superoxide gas can be continuously and stably delivered into the nasal cavity.

[0090] Furthermore, the articulated frame 6, serving as the connecting bridge between the U-shaped tube 31 and the occlusal member 1, not only possesses excellent structural strength but also provides a reliable support foundation for the swinging motion of the nasal tube 3. The articulated frame 6 further enhances the flexibility and adaptability of the nasal tube 3 in terms of spatial posture, enabling the entire nasal delivery system to better match the facial contours and usage needs of different patients.

[0091] In summary, the forward extension design of the articulated frame 6 significantly improves both structural functionality and user experience. On one hand, it optimizes the spatial layout of the nasal tube 3, creating a clearance area for the upper lip and enhancing wearing comfort and stability. On the other hand, it strengthens the connection reliability between the U-shaped tube 31 and the occlusal element 1, providing excellent structural support for subsequent multi-degree-of-freedom adjustments. Combined with the axial sliding adjustment of the oral tube 2, the multi-mode switching of the three-way valve 4, and the height and spacing adjustment functions of the nasal output end, the entire oral cavity and upper respiratory tract disinfection and purification device achieves highly adaptable treatment for different patients and different anatomical structures, possessing multiple advantages such as reasonable structure, convenient operation, high safety, and wide applicability.

[0092] Specifically, the hinge frame 6 may include a fixed frame and a sliding frame, which are slidably connected. The fixed frame is hinged to the biting member 1, and the sliding member is fixedly connected to the horizontal section 311, which further provides the nasal tube 3 with a degree of freedom for lifting and lowering, and further improves the flexibility of use of the oral cavity and upper respiratory tract disinfection and purification device.

[0093] In this invention, the movable links must have a certain degree of damping when relative movement occurs between components. For example, the hinge relationship between the hinge frame 6 and the engaging member 1 must have a certain degree of damping; the horizontal section 311 and the vertical section 312 must have a certain degree of damping when sliding relative to each other; the fixed section 3121 and the sliding section 3122 must have a certain degree of damping when sliding relative to each other; the gear 51 must have a certain degree of damping when rotating; and the rotating tube 314 must also have a certain degree of damping when rotating, in order to ensure the overall stability of the device.

[0096] The nasal tube 3 also includes a flexible contact layer sleeved on the second output end 31a.

[0097] In this embodiment, the flexible contact layer is made of a flexible and biocompatible material, such as medical-grade silicone or soft thermoplastic elastomer, which can fit closely around the patient's nostrils while avoiding local pressure, discomfort or skin damage caused by excessively hard materials.

[0098] Reference Figures 1-3 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0099] The ozone supply device is a portable ozone generator that serves as the gas supply unit for the entire oral cavity and upper respiratory tract disinfection and purification system. This generator can instantly produce ozone gas on-site, meeting the demand for highly efficient sterilizing gas during treatment. Its portable design makes the device suitable not only for professional medical environments such as hospitals and clinics, but also for a wide range of scenarios including home care, mobile healthcare, emergency situations, and long-distance transportation, significantly improving its applicability and flexibility.

[0100] The generator, in conjunction with the three-way valve 4 of the device, can supply air to the oral cavity fitting 2, the nasal cavity fitting 3, or both simultaneously, supporting various treatment modes for oral and nasal cavity disinfection, either individually or in combination. Combined with the aforementioned multi-degree-of-freedom adjustable structures, such as axial adjustment of the oral cavity fitting 2, height and spacing adjustment of the nasal cavity fitting 3, and a flexible contact layer, the entire system can be personalized according to different patients' anatomical structures and treatment needs, achieving a precise, efficient, and comfortable disinfection experience.

[0101] Furthermore, portable ozone generators can integrate intelligent control systems, such as timed operation, concentration feedback, low battery warning, and overload protection, further enhancing the ease of use and safety of the equipment. Their modular design also facilitates later maintenance and replacement of core components, extending the equipment's lifespan and reducing operating costs.
