For example, drug therapy may be accompanied by side effects or drug resistance problems, and some physical therapy may be inconvenient for widespread use due to complex operation or limited application range. With the increasing concern for health and the increasing demand for non-invasive and efficient treatment methods, exploring new non-invasive disinfection and purification technology has become a trend.

[0035] In order to better explain the present application, so as to be understood, the following will be combined with the accompanying drawings to describe the present application in detail. Figures 1-3 The present application will be described in detail through specific embodiments. In this article, the orientation of the terms such as "up", "down" and the like is referred to the orientation of the drawings. Figure 1

[0036] Example 1:

[0037] With reference to Figures 1-3 The embodiment of the present application provides an oral cavity and upper respiratory tract disinfection and purification device, which comprises a bite piece 1, an oral cavity pipe piece 2, a nasal cavity pipe piece 3 and an ultrasonic oxygen supply device. The input ends of the oral cavity pipe piece 2 and the nasal cavity pipe piece 3 can selectively communicate with the ultrasonic oxygen supply device to output ultrasonic oxygen. The middle part of the bite piece 1 is formed with a first channel, and the outer periphery of the bite piece 1 is formed with a bite part 1b suitable for the bite of a patient. The oral cavity pipe piece 2 is supported in the first channel and has a first output end 2a at one end. When the patient bites the bite part 1b, the first output end 2a extends into the oral cavity of the patient. The nasal cavity pipe piece 3 comprises a U-shaped pipe 31, and the two ends of the U-shaped pipe 31 are two second output ends 31a. The U-shaped pipe 31 is hinged to the bite piece 1 along a transverse axis and can be swung between a use position and an idle position. In the use position, the two second output ends 31a are swung upward to positions corresponding to the nostrils of the patient. In the idle position, the two second output ends 31a are swung downward to positions away from the nostrils of the patient.

[0038] In this embodiment, the oral cavity and upper respiratory tract disinfection and purification device realizes a convenient and comprehensive disinfection mode by organically combining the bite piece 1, the oral cavity pipe piece 2, the nasal cavity pipe piece 3 and the ultrasonic oxygen supply device. The bite piece 1 is provided with a first channel in the middle part, and the outer periphery is designed with a bite part 1b for the patient to bite. The bite part 1b not only plays a role in fixing the position of the device, but also can keep the oral cavity open when the patient bites, which is convenient for the oral cavity pipe piece 2 to stably deliver ultrasonic oxygen into the oral cavity. The oral cavity pipe piece 2 is supported in the first channel, and one end thereof serves as a first output end 2a which can extend to the deep part of the oral cavity in the patient's biting state, thereby realizing efficient coverage and continuous disinfection of the internal space of the oral cavity. ​

[0039] The nasal cavity tube 3 adopts a U-shaped tube 31 structure, and two ends serve as second output ends 31a, corresponding to the two nostrils of the patient respectively. The U-shaped tube 31 is articulated on the bite piece 1 through a transverse axis, and can be flexibly switched between a use position and an idle position. When in the use position, the two second output ends 31a swing upward to align with the nostrils, so as to accurately guide the hyperox to the nasal cavity and the upper respiratory tract area thereof, and realize the purification of the inside of the nasal cavity; when in the idle position, the second output ends 31a swing downward and away from the nostrils, so as to avoid interfering with the normal breathing or movement of the patient, and also facilitate the storage and cleaning of the device.

[0040] The input ends of the oral cavity tube 2 and the nasal cavity tube 3 can be selectively communicated with the hyperox supply device, so that the user can select to use the oral cavity or the nasal cavity alone for disinfection according to actual needs, or simultaneously use both channels for disinfection, thereby improving the flexibility and adaptability of treatment. This multi-mode switching mode not only enhances the practicality of the device, but also improves the individualization level of treatment.

[0041] Through integrated design, disinfection of the oral cavity and the upper respiratory tract is realized, and the treatment efficiency is improved; the design of the bite piece 1 not only helps to fix the device, but also effectively prevents the displacement or displacement of the pipeline caused by the closure of the oral cavity, and ensures the stability of the treatment process; the swingable structure of the nasal cavity tube 3 makes it retractable when not in use, reducing space occupation and improving use convenience; at the same time, hyperox, as a strong natural oxidant, has broad-spectrum bactericidal ability and can quickly kill a variety of pathogenic microorganisms, and has no residue and no drug resistance, and is suitable for the prevention and adjuvant treatment of various oral cavity and upper respiratory tract infections. Therefore, the device has good popularization value and practical prospect in clinical application.

[0042] Specifically, the concentration of hyperox is controlled within a safe range to avoid excessive irritation to the patient's anterior module and cause discomfort.

[0043] The shape of the bite part 1b matches the shape of the upper and lower jaw teeth of the patient, and a groove with a certain depth can be provided on the bite part 1b to assist the positioning of the bite part 1b. The bite piece 1, the oral cavity tube 2 and the nasal cavity tube 3 can be a set of components for a specific person, and need to be fully sterilized after each use to avoid infection, or be set as a disposable assembly to improve use convenience and further avoid secondary infection.

[0044] The main body mechanism of the bite piece 1, the oral cavity tube 2 and the nasal cavity tube 3 can be made of medical plastic material.

[0045] The articulated connection between the U-shaped tube 31 and the bite piece 1 has a certain damping, at least to enable the U-shaped tube 31 to be kept in the use position.

[0046] Example 2:

[0047] Referring to Figures 1-3 In addition to all the technical solutions of the above-mentioned embodiments, the embodiments of the present application further have the following technical solutions:

[0048] It also includes a three-way valve 4 supported on the oral tube 2, and three ports are respectively communicated with the input end of the oral tube 2, the input end of the nasal tube 3 and the superoxygen supply device,

[0049] The three-way valve 4 can be switched to an oral output state of outputting gas from the first output end 2a, a nasal output state of outputting gas from the second output end 31a, or a double output state of simultaneously outputting gas from the first output end 2a and the second output end 31a.

[0050] In this embodiment, by adjusting the working state of the three-way valve 4, different modes of gas delivery selection can be realized. Specifically, the three-way valve 4 can be switched to an oral output state of outputting superoxygen only from the oral tube 2, a nasal output state of outputting superoxygen only from the nasal tube 3, and a double output state of outputting superoxygen from the oral cavity and the nasal cavity at the same time, not only improving the functional diversity of the device, but also enhancing its adaptability in different clinical scenarios. For example, when only the oral cavity needs to be disinfected, the oral output state can be selected to avoid unnecessary irritation to the nasal cavity; when treating upper respiratory tract infection or nasal inflammation, the nasal output state can be switched to achieve precise treatment; for the case of overall purification of the oral cavity and the upper respiratory tract, such as preoperative preparation or high-risk environment, the double output state can be enabled to achieve simultaneous disinfection of multiple sites and improve treatment effect.

[0051] Specifically, the three-way valve 4 can be fixedly connected to the end of the oral tube 2 away from the oral cavity, so as to be indirectly supported on the occlusion piece 1, and the three-way valve 4 is in communication with the nasal tube 3 through a hose, thereby ensuring the compactness of the overall structure of the device.

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

[0053] Embodiment 3:

[0054] Referring to Figures 1-3 In addition to all the technical solutions of the above-mentioned embodiments, the embodiments of the present application further have the following technical solutions:

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

[0056] The sleeve 1c is fixedly connected to the bite piece 1, the oral tube 2 has a limiting portion 2b, and the oral tube 2 is axially and slidingly connected in the sleeve 1c; when the limiting portion 2b abuts against the end of the sleeve 1c, the longest length of the oral tube 2 extending into the oral cavity of the patient is ensured.

[0057] In the embodiment, the first output end 2a can be adjusted in position according to the depth of the position to be treated in the oral cavity of the patient, so that the hyperoxygenated gas can be accurately delivered to the target area in the oral cavity. Such a structure not only improves the individualized adaptation capability of the device, but also enhances the targeting and effectiveness of the treatment.

[0058] The limiting portion 2b slides in the sleeve 1c together with the oral tube 2, and abuts against the end of the sleeve 1c when sliding to the end of the sleeve 1c, so as to limit the oral tube 2 from continuing to extend in the oral cavity direction, avoiding discomfort or injury caused by over-insertion. While ensuring the safety of use, it is also convenient for medical staff or patients to quickly adjust the position of the output end according to the actual situation.

[0059] Specifically, the limiting portion 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 tube 2.

[0060] Embodiment 4:

[0061] With reference to Figures 1-3 In addition to having all the technical solutions of the above-mentioned embodiments, the embodiments of the present application further have the following technical solutions:

[0062] The U-shaped tube 31 includes a horizontally extending horizontal section 311, and two vertically extending vertical sections 312 respectively axially and sealingly slidingly connected to two ends of the horizontal section 311, and the middle part of the horizontal section 311 is hingedly connected to the bite piece 1; the upper end outlet of the two vertical sections 312 forms a second output end 31a, and the two vertical sections 312 can be synchronously close to or synchronously away from the horizontal section 311 to adjust the output height of the two second output ends 31a.

[0063] In the embodiment, the U-shaped tube 31 includes a horizontally extending horizontal section 311, and two vertically extending vertical sections 312 respectively connected to two ends of the horizontal section 311, and the upper ends of the two vertical sections 312 serve as second output ends 31a, corresponding to two nostrils of the patient. The middle part of the horizontal section 311 is hingedly connected to the bite piece 1, so that the entire U-shaped tube 31 can be switched between the use position and the idle position, facilitating operation and storage.

[0064] The two vertical segments 312 can be synchronously moved closer to or away from the horizontal segment 311, so as to adjust the height positions of the two second output ends 31a. Such a structural design enables the output ends to be flexibly adapted to the face height and nostril positions of different patients, ensuring that the hyperoxic gas can be accurately delivered to the nasal entrance, and improving the accuracy and comfort of treatment. For example, for patients with higher faces or higher nostril positions, the height of the second output end 31a can be raised by moving the two vertical segments 312 away from the horizontal segment 311; and for patients with flatter faces or lower nostril positions, the vertical segments 312 can be moved closer to the horizontal segment 311 to lower the height of the output end, so as to achieve personalized adaptation.

[0065] Such an adjustable structure not only enhances the adaptability of the device, but also effectively avoids the problems of gas leakage or reduced delivery efficiency caused by mismatched output end positions. By synchronously adjusting the relative positions of the two vertical segments 312, it is also possible to ensure that the two output ends are symmetrical, further improving the user experience and treatment effect.

[0066] In summary, the height adjustment function of the U-shaped tube 31 structure is combined with the swing switching function, so that the nasal tube 3 is more flexible and reliable in use, and can maintain good adaptability and functionality in different application scenarios. In combination with the axial adjustment structure of the oral tube 2 and the multi-mode switching function of the three-way valve 4, the oral and upper respiratory tract disinfection and purification device realizes all-around, personalized and efficient disinfection of the oral cavity and upper respiratory tract, and has good clinical application prospects.

[0067] Embodiment 5:

[0068] With reference to Figures 1-3 In addition to having all the technical solutions of the above-mentioned embodiments, the embodiments of the present application further have the following technical solutions:

[0069] The nasal tube 3 further comprises a support segment 313 and a rotating tube 314, which are vertically extended. The lower part of the rotating tube 314 is axially and rotatably connected to the middle part of the horizontal segment 311, and the support segment 313 is threadedly connected to the upper part of the rotating tube 314. The two second output ends 31a are both supported on the support segment 313. The vertical segment 312 comprises a fixed segment 3121 and a sliding segment 3122. The fixed segment 3121 is connected to the horizontal segment 311, and the sliding segment 3122 is axially and sealingly slidably connected to the upper end of the fixed segment 3121. The upper end of the sliding segment 3122 forms the second output end 31a. When the rotating tube 314 is rotated, the support segment 313 can synchronously drive the two sliding segments 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 installed at the middle position of the horizontal section 311 by an axial rotating connection mode, which ensures smooth rotation around the central axis of the horizontal section 311 while maintaining axial fixation to avoid unnecessary axial displacement. The support section 313 is connected to the upper part of the rotating tube 314 by a threaded connection, so that the support section 313 can produce axial lifting movement with the rotation of the rotating tube 314. The two 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 adjust their vertical height synchronously.

[0071] Further, the sliding section 3122 is nested in the upper end of the fixed section 3121 in an axial sealing sliding manner. This sealing sliding connection not only ensures the sealing of the gas or fluid during transmission in the vertical section 312, preventing leakage, but also allows smooth up and down movement of the sliding section 3122 relative to the fixed section 3121. The upper end of the sliding section 3122 is the second output end 31a, so the change of its position directly determines the height of the output port.

[0072] When the user operates the rotating tube 314 to rotate, due to the threaded connection between the support section 313 and the rotating tube 314, the rotation of the rotating tube 314 will be converted into the axial displacement of the support section 313, which in turn drives the two sliding sections 3122 supported thereon to rise or fall synchronously. This linkage mechanism realizes precise and synchronous adjustment of the height of the two second output ends 31a. Since the movements of the two sliding sections 3122 are completely synchronized, it can effectively ensure that the two output ends always remain consistent during height adjustment, avoiding the use of unsuitable or connection problems caused by height deviation.

[0073] Firstly, the height adjustment is achieved by the threaded cooperation of the rotating tube 314 and the support section 313, which is simple to operate and has high adjustment accuracy. The user only needs to rotate the rotating tube 314 to complete the height setting without the need for complex tools or steps. Secondly, the support section 313 supports two sliding sections 3122 simultaneously, ensuring the synchronous lifting of the two output ends and improving the symmetry and stability of the adjustment, avoiding structural imbalance caused by unilateral adjustment. Thirdly, the axial sealing sliding connection between the sliding section 3122 and the fixed section 3121 not only realizes the height adjustment function, but also guarantees the sealing performance of the gas passage, improving the safety and reliability of the equipment.

[0074] Through this device, first, the precision and comfort of treatment can be improved by adjusting the structure in multiple dimensions to adapt to different patient anatomical features. Secondly, the convenience and safety of operation can be enhanced, avoiding problems caused by structural misalignment or gas leakage, which has good clinical promotion value and market application prospect.

[0075] Embodiment 6:

[0076] Referring to Figures 1-3 In addition to the above-mentioned technical solutions, the embodiments of the present application further have the following technical solutions:

[0077] The distance adjusting member 5 comprises a gear 51, a knob 52 and two racks 53. The gear 51 cavity is formed in the support section 313, and the gear 51 is rotatably connected in the gear 51 cavity. The knob 52 is fixedly connected with the gear 51 and located outside the gear 51 cavity. One end of each of the two racks 53 is fixedly connected with the corresponding output end, and the other end of each of the two racks 53 penetrates the side wall of the gear 51 cavity and is engaged with the upper and lower sides of the gear 51, respectively, so that the two racks 53 form the support member between the support section 313 and the vertical section 312.

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

[0079] The second sliding sleeve has good elasticity and sealing performance, not only can maintain the continuity of the gas path, but also allows the 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 tube 3. This flexible connection mode provides a structural basis for subsequent distance adjustment, while ensuring the continuity and stability of gas delivery.

[0080] The gear 51 cavity is provided inside the support section 313, and the gear 51 is rotatably connected in the gear 51 cavity. The center of the gear 51 is fixedly connected with the knob 52, and the knob 52 is located outside the gear 51 cavity, which is convenient for user operation. The two racks 53 are arranged on the two sides of the gear 51, and one end of each of the two racks 53 is fixedly connected with the corresponding vertical section 312, and the other end of each of the two racks 53 penetrates the side wall of the gear 51 cavity and is engaged with the upper and lower sides of the gear 51. When the user rotates the knob 52, the gear 51 is driven to rotate synchronously, and then drives the two racks 53 to move in opposite directions, thereby realizing the lateral distance adjustment between the two vertical sections 312.

[0081] The structure design of the distance adjusting member 5 is ingenious, which realizes the synchronous and symmetrical adjustment of the two output ends through the gear 51-rack 53 linkage mechanism, ensures that the output ends are always in a symmetrical position, and avoids the discomfort of wearing or uneven gas delivery caused by deviation.

[0082] In addition, the rack 53 not only serves as a transmission member, but also serves as a support member of the vertical section 312, which realizes one piece with multiple uses and further improves the compactness of the structure of the device.

[0083] In summary, by introducing the second sliding sleeve and the spacing adjustment member 5, the nasal tube 3 realizes flexible adjustment of the lateral spacing, further improving the applicability and practicality of the device in clinical application. Combined with the axial adjustment function of the oral tube 2, the multi-mode switching function of the three-way valve 4, and the stable support function of the bite piece 1, the entire oral and upper respiratory tract disinfection and purification device forms a personalized, safe and reliable treatment system, which is suitable for various clinical scenarios, such as oral preoperative and postoperative disinfection, upper respiratory tract infection control, respiratory disease auxiliary treatment, and preventive use in high-risk infection environments, etc., and has significant clinical popularization value and broad application prospect.

[0084] Specifically, the axis of the gear 51 can be arranged perpendicular to the facial plane of the patient, and the rack 53 can be arranged in a special shape, for example, a long strip-shaped medical plastic part is formed with teeth in the middle part and sliding strips on both sides. In this way, the gear 51 cooperates with the teeth, and the sliding strips can slide with the side wall of the cavity of the gear 51, thereby realizing the support of the vertical section 312 while maintaining the sliding cooperation between the rack 53 and the side wall of the cavity of the gear 51.

[0086] Referring to Figures 1-3 In addition to having all the technical solutions of the above-mentioned embodiments, the embodiments of the present application further have the following technical solutions:

[0087] The horizontal section 311 is fixedly connected with a hinged frame 6, and the horizontal section 311 is hinged with the bite piece 1 through the hinged frame 6. The hinged frame 6 extends forward to enable the U-shaped tube to extend forward to form a displacement area for the upper lip of the patient.

[0088] In this embodiment, the device is additionally provided with a forwardly extending hinged frame 6 on the horizontal section 311, so that the U-shaped tube 31 is hingedly connected with the bite piece 1 through the hinged frame 6. This not only enhances the stability of the U-shaped tube 31 when swinging between the use position and the idle position, but more importantly, the forwardly extending structure of the hinged frame 6 provides a more reasonable space guide for the overall layout of the U-shaped tube 31, so that the U-shaped tube 31 can extend forward when swinging to the use position, thereby forming an upper lip displacement area on the patient's face.

[0089] The design of the upper lip displacement area fully considers the characteristics of the human facial structure. In particular, when the nasal tube 3 is in the use state, the forwardly extending posture of the U-shaped tube 31 can naturally avoid the upper lip area of the patient, avoiding the compression or discomfort caused by the contact between the tube and the upper lip, and improving the comfort of wearing. At the same time, this forward displacement structure also helps to maintain the alignment stability between the output end of the nasal tube 3 and the nostril, avoiding the deviation of the tube caused by the slight movement of the patient or the facial muscle movement, thereby ensuring that the hyperoxic gas can be continuously and stably delivered to the inside of the nasal cavity.

[0090] In addition, the articulated frame 6 serves as a connecting bridge between the U-shaped tube 31 and the occlusion piece 1, not only having good structural strength, but also providing a reliable support basis for the swinging action of the nasal cavity tube 31. The articulated frame 6 further enhances the flexibility and adaptability of the nasal cavity tube 31 in space posture, enabling the entire nasal cavity delivery system to better match the facial profiles and use requirements of different patients.

[0091] In summary, the forward extension design of the articulated frame 6 brings significant improvement in both structural function and user experience. On the one hand, it optimizes the spatial layout of the nasal cavity tube 31, forming an upper lip accommodation area, improving the comfort and stability of wearing; on the other hand, it strengthens the connection reliability between the U-shaped tube 31 and the occlusion piece 1, providing good structural support for subsequent multi-degree of freedom adjustment. Combined with the axial sliding adjustment of the oral cavity tube 2, the multi-mode switching of the three-way valve 4, and the height and spacing adjustment function of the nasal cavity output end, the entire oral and upper respiratory tract disinfection and purification device realizes high adaptability treatment for different patients with different anatomical structures, with multiple advantages such as reasonable structure, convenient operation, high safety, and wide application range.

[0092] Specifically, the articulated frame 6 can include a fixed frame and a sliding frame, which are slidingly connected, the fixed frame is articulated with the occlusion piece 1, and the sliding piece is fixedly connected with the horizontal segment 311, further providing the nasal cavity tube 31 with a lifting degree of freedom, further improving the use flexibility of the oral and upper respiratory tract disinfection and purification device.

[0093] The movable link in the present application has certain damping when the relative motion occurs between the components, for example, the articulated relationship between the articulated frame 6 and the occlusion piece 1 has certain damping, the horizontal segment 311 and the vertical segment 312 have certain damping when they slide relative to each other, the fixed segment 3121 and the sliding segment 3122 have certain damping when they slide relative to each other, the gear 51 has certain damping when it rotates, and the rotating tube 314 also has certain damping when it rotates, to ensure the overall stability of the device.

[0094] Embodiment 8:

[0095] Referring to Figures 1-3 In addition to the above-mentioned technical solutions of the embodiments of the present application, the embodiments of the present application further have the following technical solutions:

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

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

[0098] Referring Figures 1-3 In addition to the above-mentioned embodiments, the embodiments of the present application further have the following technical solutions:

[0099] The superoxygen supply device is a portable superoxygen generator, which is a gas supply unit of the entire oral cavity and upper respiratory tract disinfection and purification device. The generator can generate superoxygen gas on site in real time to meet the demand for high-efficiency disinfection gas during treatment. The portability design makes the device not only suitable for professional medical environments such as hospitals and clinics, but also widely applicable to family nursing, mobile medical treatment, emergency sites, long-distance transportation tools and other scenarios, significantly improving the application range and use flexibility of the device.

[0100] The generator is used in cooperation with the three-way valve 4 structure of the device, which can realize gas supply to the oral cavity pipe 2, the nasal cavity pipe 3 or both at the same time, support multiple treatment modes of oral cavity, nasal cavity disinfection alone or in combination. Combined with the aforementioned multi-degree-of-freedom adjustment structure such as the axial adjustment of the oral cavity pipe 2, the height and spacing adjustment of the nasal cavity pipe 3, the flexible contact layer, etc., the entire system can be personalized according to different patient anatomical structures and treatment needs, realizing precise, efficient and comfortable disinfection experience.

[0101] In addition, the portable superoxygen generator can also integrate an intelligent control system, such as setting a timing operation, concentration feedback, low power prompt, overload protection and other functions, further improving the convenience and safety of device use. Its modular design also facilitates later maintenance and replacement of core components, prolongs the service life of the device and reduces the use cost.
