Description

Technical Field

[0001] The embodiments of the present invention relate to the clinical treatment field of otolaryngology, and particularly to a nasal spray device for otolaryngology. Background Technology

[0002] In clinical treatment and daily care in otolaryngology, nasal spray devices are increasingly used and their importance is becoming more and more prominent as an important local drug delivery tool.

[0003] Currently available nasal spray devices have several limitations. In terms of spray coverage, most devices use a fixed fan-shaped or columnar spray pattern, and the spray angle and area cannot be dynamically adjusted. For example, in the treatment of allergic rhinitis, when nasal mucosal edema is concentrated in the middle turbinate region, the fixed spray angle of 15°-25° in traditional devices leads to a large amount of medication deposited in the nasal vestibule, with the actual drug concentration at the lesion site less than 30% of the effective dose. Furthermore, for sinusitis patients, if the spray cannot be accurately delivered to the sinus opening area, even multiple administrations may not achieve the desired therapeutic effect.

[0004] Regarding operational stability, existing devices generally lack ergonomic design. Clinical surveys conducted in tertiary hospitals revealed that 76.3% of patients experienced device misalignment during self-operation, particularly elderly patients and children, whose weaker hand control resulted in spray point errors of 1.5-3 cm. This error not only reduces drug utilization but may also cause adverse reactions such as coughing and nasal mucosal damage.

[0005] In terms of functional integration, existing devices generally adopt a single-function module design. For example, although some products are equipped with adjustable nozzles, the adjustment process requires interrupting the drug delivery operation; a few devices with fixed functions have nasal pad structures and spray angles that are completely independent and cannot automatically adapt to the nasal cavity anatomy. This functional fragmentation leads to cumbersome clinical operation procedures. Statistics show that an average of 45 seconds is required for parameter adjustment each time, which seriously affects patient compliance.

[0006] These technological bottlenecks not only increase treatment costs but also directly affect disease outcomes. Therefore, developing a new type of nasal spray device that combines intelligent adjustment and precise fixation is an urgent problem to be solved. Summary of the Invention

[0007] The purpose of this invention is to provide at least one nasal spray device for otolaryngology, which can at least solve the technical problems of insufficient medication at the lesion site in the nasal cavity and easy misplacement of medication during administration, and can at least achieve the technical effect of fixed-position medication and targeted medication at the lesion site.

[0008] To address the aforementioned technical problems, at least one embodiment of this application provides a nasal spray device for otolaryngology, comprising a spray assembly and an adjustment assembly. The adjustment assembly is connected to the spray assembly. The spray assembly includes a spray outlet for atomizing and spraying medication. The adjustment assembly includes a spray adjustment mechanism 2, which is fitted to the spray outlet. Adjusting the spray adjustment mechanism is used to adjust the size of the spray outlet of the spray assembly and the angle at which the medication is dispensed from the spray outlet, thereby controlling the amount of atomized medication and the angle at which the atomized medication is dispensed.

[0009] The embodiments of this application provide a nasal spray device for otolaryngology, which, compared with the prior art, uses an adjustment component to adjust the size of the spray outlet and the angle of drug delivery, thus solving the problem of insufficient drug delivery to lesion parts in the nasal cavity.

[0010] In addition, the medicine bottle 8, support rod 5, nebulizer 83, and spray outlet 4 are described. One end of the support rod 5 is connected to the nebulizer 83 and the spray outlet 4, and the other end is connected to the medicine bottle 8. This is used to spray the medicine atomized by the nebulizer 83 from the spray outlet 4 to act on the lesion site. Using a nebulizer to atomize the medicine can make the medicine act more fully on the lesion site, improve the medication effect, enhance the absorption efficiency of the nasal mucosa, and enhance the treatment effect.

[0011] In addition, the adjustment assembly includes: an adjustment control mechanism 10, an adjustment mechanism 3, and a spray adjustment mechanism 2 connected in sequence; the spray adjustment mechanism 2 is located on the outer surface of the spray outlet 4 and fits against the spray outlet 4; the adjustment mechanism 3 is fixedly connected to the support rod 5; one end of the adjustment control mechanism 10 is rotatably mounted on the medicine bottle 8, and the other end is movably connected to the adjustment mechanism 3; when the adjustment control mechanism is in the first position, it drives the adjustment mechanism 3 to operate, and the operation of the adjustment mechanism 3 drives the spray adjustment mechanism 2 to operate, controlling the spray angle and spray volume of the spray outlet 4.

[0012] The regulating control mechanism is used to control the operation of the adjustment mechanism. The operation of the adjustment mechanism drives the operation of the spray adjustment mechanism, thereby realizing the control of the spray volume and spray angle at the spray outlet.

[0013] In addition, the spray adjustment mechanism 2 includes a spray regulator 21 and an adjustment platform 22. The spray regulator 21 and the adjustment platform 22 are slidably connected. When the spray regulator 21 slides along the adjustment platform 22, it can contract or expand to adjust the spray outlet angle and size. The adjustment platform supports the sliding of the spray regulator, thereby adjusting the spray regulator to adjust the spray outlet size and angle, and realizing the control of the drug application angle and dosage.

[0014] In addition, the spray regulator 21 includes a movably connected spray umbrella 212 and an opening and closing structure 211. The spray umbrella 212 is attached to the spray outlet 4 and has a triangular structure. The first end is fixed to the front end of the spray outlet, the second end is fixedly connected to the opening and closing structure 211, and the third end is engaged with the opening and closing structure. When the opening and closing structure 211 is running, it drives the third end of the spray umbrella 212 to run, thereby driving the spray umbrella 212 to open or close, controlling the size of the spray outlet. By using the opening and closing structure to control the opening and closing of the spray umbrella, and using the opening and closing of the spray umbrella to control the spray outlet, the dosage control under layered control is realized.

[0015] In addition, the spray umbrella 212 includes: several frames 2121 and blades 2122. One end of all the frames is movably connected together, and the other end is fixedly connected to the opening and closing structure 211. The blades 2122 are triangular structures. Their first end is connected to the movable connection end of all the frames, their second end is fixedly connected to the first frame, and their third end is fixedly connected to the last frame. When the opening and closing structure is running, the frames open or close, which drives the blades 2122 to open or close.

[0016] The opening and closing of the umbrella-shaped structure with a frame allows for control over the size of the spray outlet.

[0017] Furthermore, the adjustment platform 22 is a circular ring structure. A groove 224 is provided at the edge of the inner hole of the ring. The sliding block of the opening and closing structure 211 is disposed within the groove for movement along it. A positioning boss 221 is provided on the outer surface of the circular ring structure for engaging with the adjustment mechanism 3 to fix the position of the adjustment platform. The groove on the adjustment platform allows the frame to move along it, thus controlling the opening and closing of the spray umbrella.

[0018] In addition, the adjustment mechanism 3 includes an adjustment gear ring 35 and a connector 33 that are movably connected. The connector 33 is located inside the adjustment gear ring 35. The top view of the connector is circular. A through hole 34 is opened in the middle of the circle of the connector 33 for engaging with the support rod 5. The adjustment gear ring 35 is a hollow cylindrical structure. The upper opening of the adjustment gear ring 35 is provided with upper teeth 32 for engaging with the opening and closing structure 211. The lower opening of the adjustment gear ring 35 is provided with lower teeth 36 for engaging with the adjustment control mechanism 10.

[0019] The connector is used to fix the position of the adjustment mechanism in the nasal spray device. The adjustment ring is equipped with upper and lower teeth to convert the rotation of the lower part of the adjustment ring to the rotation of the upper part, thereby driving the spray adjustment mechanism on the upper part of the connector to operate, thus realizing the control of the angle of the spray outlet.

[0020] In addition, the nasal spray device also includes a fixing component connected to the spray component. The fixing component includes a first fixing mechanism 1, a second fixing mechanism 9, a third fixing mechanism 6 and a fourth fixing mechanism 7. The first fixing mechanism 1 is disposed at the front end of the spray outlet 4 in the spray component and is used to fix the position of the spray outlet inside the nasal cavity. The second fixing mechanism 9, the third fixing mechanism 6 and the fourth fixing mechanism 7 are disposed in the middle of the spray component and are used to fix the position of the spray device from outside the nasal cavity.

[0021] The first fixing mechanism 1 is used to fix the nasal spray device in the nasal cavity, and the second, third and fourth fixing mechanisms are used to fix the nasal spray device outside the nasal cavity, which ensures the fixation of the nasal spray device during use and improves the accuracy of the spray landing point.

[0022] In addition, the adjustment and control mechanism includes a first gear structure and a second gear structure connected in sequence. The second shaft 1022 of the second gear structure is fitted onto one end of the first gear shaft 1013 of the first gear structure. A handle 1011 is provided on the other end of the first gear shaft 1013, and the end of the other end is movably disposed on the outer surface of the medicine bottle. The first gear 1012 in the first gear structure is used to mesh with the lower tooth 36 in the adjustment mechanism 3. The second gear 1021 in the second gear structure is used to mesh with the inner tooth in the third fixing mechanism. When the first gear 1012 meshes with the lower tooth 36, the second gear 1021 disengages from the inner tooth 72 in the third fixing mechanism to adjust the size of the spray outlet. When the second gear 1012 meshes with the inner tooth 72 in the third fixing mechanism, the first gear 1012 disengages from the lower tooth 36 to fix the nasal spray device outside the nasal cavity.

[0023] Different gears are used to control the fixing and adjusting components respectively. A single control handle is used to control the dosage and fixed position of the medicine, which simplifies the operation and improves the precision control of the application site and dosage.

[0024] In addition, the first fixing mechanism is a circular structure with a certain thickness, used to fix the position of the spray outlet inside the nasal cavity; the third fixing mechanism 6 and the fourth fixing mechanism 7 are fixed on the support frame 5. The third fixing mechanism 6 is provided with a first sector-shaped hole 62, and the fourth fixing mechanism 7 is provided with a second sector-shaped hole 71. The edge structure of the first sector-shaped hole 62 and the second sector-shaped hole 71 are the same, and they are in the same position in the axial direction of the support frame 5; an internal tooth 72 is provided on the inner side of the edge of the second sector-shaped hole, which is used to mesh with the second gear 1012 in the adjustment and control mechanism to drive the second fixing mechanism to fix the nasal spray device.

[0025] The first fixing mechanism, which adopts a circular structure, is fixed in position inside the nasal cavity, ensuring that the nasal spray device will not cause damage to the nasal cavity. The third fixing mechanism 6 and the fourth fixing mechanism 7 are used together to fix and rotate the second fixing mechanism 9, thereby achieving fixation of the nasal spray device from the outside of the nasal cavity and reducing displacement.

However, the technical solutions claimed in the present invention can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0029] Example 1: Embodiments of the present invention relate to a nasal spray device for use in otolaryngology.

[0030] Compared with the prior art, the embodiments of the present invention employ an adjustable drug dosage adjustment component, which solves the problem that the drug concentration at the lesion site cannot meet the effective dosage requirements, and achieves precise drug delivery to the lesion site. The invention also employs a fixing component to fix the position of the spray device, which solves the problem of inaccurate spray landing point, and achieves fixation after precise positioning of the lesion site.

[0031] The following is a detailed description of the implementation details of an ENT nasal spray device according to this embodiment. The following details are provided for ease of understanding and are not necessary for implementing this solution.

[0032] The present invention provides a nasal spray device for otolaryngology, comprising: a spray assembly, an adjustment assembly, and a fixing assembly. The spray assembly is used to atomize and spray medication. The adjustment assembly is connected to the spray assembly and is used to adjust the amount of atomized medication and the spray angle. The fixing assembly is connected to the spray assembly and is used to fix the position of the spray device inside and outside the nasal cavity.

[0033] The adjustment and fixing components are fixedly mounted on the spray assembly.

[0034] like Figure 1As shown, the fixing assembly includes a first fixing mechanism 1 inside the nasal cavity and a second fixing mechanism 9 outside the nasal cavity. The first fixing mechanism 1 inside the nasal cavity is used to determine the position of the spray outlet in the spray device inside the nasal cavity during use, and the second fixing mechanism 9 outside the nasal cavity is used to fix the spray device outside the nasal cavity during use. The first fixing mechanism 1 inside the nasal cavity is fixedly connected to the adjustment assembly and is located at the front end of the adjustment assembly, that is, at the front end of the entire nasal spray device. The second fixing mechanism 9 outside the nasal cavity is fixedly connected to the spray assembly and is located on the outer side of the adjustment assembly and the fixing assembly.

[0035] The second external fixation mechanism 9 includes a third fixation mechanism 6, a fourth fixation mechanism 7, and a pressing mechanism 92. The third fixation mechanism 6 and the fourth fixation mechanism 7 are used to fix the pressing mechanism 92 to the spray assembly.

[0036] The spray assembly includes a medicine bottle 8, a support rod 5, an atomizer 83, and a spray outlet 4. The spray outlet 4 is connected to one end of the support rod 5, and one end of the support rod 5 is connected to the atomizer 83 and the spray outlet 4, while the other end is connected to the medicine bottle 8. During use, the atomizer 83 atomizes the medication in the medicine bottle 8 and sprays it out from the spray outlet 4, applying it to the affected area.

[0037] A third fixing mechanism 6 and a fourth fixing mechanism 7 are fixedly installed on the support rod 5. The third fixing mechanism 6 is fixedly connected to the support rod 5, and the fourth fixing mechanism 7 is rotatably connected to the support rod 5. A gear 72 is provided on the fourth fixing mechanism 7 for meshing with the adjustment component.

[0038] The adjustment assembly includes an adjustment control mechanism 10, an adjustment mechanism 3, and a spray adjustment mechanism 2, which are connected sequentially. The spray adjustment mechanism 2 is located on the outer surface of the spray outlet 4 and fits against the spray outlet 4. The adjustment mechanism 3 is fixedly connected to the support rod 5. One end of the adjustment control mechanism 10 is rotatably mounted on the medicine bottle, and the other end is connected to the fixing assembly and the adjustment assembly, used to adjust the second fixing mechanism 9 and the adjustment mechanism 3. The spray adjustment mechanism 2 is movably connected to the adjustment mechanism 3. When the adjustment control mechanism is in the first position, it drives the adjustment mechanism to move, and the movement of the adjustment mechanism drives the spray adjustment mechanism to move, controlling the spray angle and spray volume. When the adjustment control mechanism is in the second position, it drives the second fixing mechanism 9 to move, used to fix the spray device to the outside of the use area.

[0039] The adjustment and control mechanism 10 includes a first gear structure 101 and a second gear structure 102. The first gear structure 101 drives the adjustment mechanism 3, and the second gear structure 102 drives the second fixing mechanism. The gears in the first gear structure and the second gear structure are sequentially mounted on the same connecting rod.

[0040] The spray adjustment mechanism 2 includes a spray regulator 21 and an adjustment platform 22, which are slidably connected to each other and are used to adjust the spray angle and size.

[0041] The spray regulator 21 includes a spray umbrella 212 that can be opened and closed and an opening and closing structure 211 that controls the opening and closing of the spray umbrella. The opening and closing structure 211 is movably connected to the adjusting platform 22. The spray umbrella 212 fits against the spray outlet 4 and has a triangular structure. The first end is fixed to the front end of the spray outlet, the second end is fixedly connected to the opening and closing structure 211, and the third end is engaged with the opening and closing structure. When the opening and closing structure 211 is running, it drives the third end of the spray umbrella 212 to run, thereby driving the spray umbrella 212 to open or close and control the size of the spray outlet.

[0042] The opening and closing structure 211 is engaged with the adjusting mechanism 3, and when the adjusting mechanism is activated, it drives the opening and closing structure to move.

[0043] The spray umbrella 212 includes several frames 2121 and blades 2122. One end of each frame is movably connected together, and the other end is fixedly connected to the opening and closing structure 211. The blades 2122 are triangular structures. Their first end is connected to the movable connection end of each frame, their second end is fixedly connected to the first frame, and their third end is fixedly connected to the last frame. When the opening and closing structure is running, the frames open or close, which in turn open or close the blades 2122.

[0044] The adjustment mechanism 3 includes an adjustment gear ring 35 and a connector 33. The connector 33 connects the spray assembly and the adjustment gear ring to connect the adjustment gear ring to the spray assembly. One end of the adjustment gear ring 35 is connected to the adjustment control mechanism 10, and the other end is connected to the spray adjustment mechanism 2. It operates under the action of the adjustment control mechanism 10, and simultaneously drives the spray adjustment mechanism 2 to adjust the spray angle and spray volume.

[0045] The adjusting gear ring 35 includes a rotating ring 31, an upper tooth 32, and a lower tooth 36. The rotating ring 31 surrounds the outer periphery of the connector 33. The upper tooth 32 is fixedly disposed at one open end of the rotating ring 31, and the lower tooth 36 is fixedly disposed at the other open end of the rotating ring 31. When the rotating ring rotates, it drives the upper tooth 32 and the lower tooth 36 to run.

[0046] The first gear 1012 in the first gear structure 101 meshes with the lower tooth 36, and the upper tooth 32 meshes with the spray adjustment mechanism 2.

[0047] This embodiment provides a nasal spray device for otolaryngology, which uses an adjustable component to adjust the spray angle and spray volume, enabling targeted medication to be applied to the lesion site, saving medication dosage, improving medication efficacy, and solving the problem of insufficient medication dosage at the lesion site.

[0048] Example 2 The embodiments of the present invention are a detailed description of the above-described Embodiment 1, see [link to Embodiment 1]. Figures 2 to 18 .

[0049] like Figure 2 As shown, the spray assembly includes a medicine bottle 8, a support rod 5, and a spray outlet 4. The support rod 5 is a hollow structure, with one end connected to the opening of the medicine bottle 8 and the other end connected to the inlet of the spray outlet 4.

[0059] The spray adjustment mechanism 2 is located between the spray outlet 4 and the first fixing mechanism 1. It fits against the spray outlet 4 and partially blocks the spray outlet to prevent the medicine from sticking to the inner surface of the spray adjustment mechanism 2 after it is sprayed out, thus causing waste. At the same time, it controls the output of the spray outlet and adjusts the amount of medicine used.

[0060] The spray outlet 4 has a hemispherical structure, and the spray adjustment mechanism 2 is an adjustable telescopic structure, including a spray regulator 21 and an adjustment platform 22. One end of the spray regulator 21 is connected to the adjustment platform 22 and can slide along the adjustment platform 22, while the other end is fixedly connected to the first fixing mechanism 1.

[0061] The spray regulator 21 includes an opening and closing spray umbrella 212 and an opening and closing structure 211 for controlling the opening and closing of the spray umbrella, such as...

Several telescopic rods are connected together to form a telescopic figure-eight structure.

[0069] At the midpoint between the two movable telescopic rods, connect the other end of a frame 2121.

[0070] When each skeleton contracts, the blade 2122 contracts; when each skeleton opens, the blade 2122 unfolds.

[0071] At the other end of each frame, a sliding block 2113 is also provided, which is located in the sliding groove 224.

[0072] The position of the sliding block 2113 connected to the first skeleton is fixed, and the drag block 2112 is fixedly set at the position where the last skeleton is connected to the sliding block. The front view of the drag block 2112 is a triangle, which is used to mesh with the teeth. When the teeth are running, the position of the drag block 2112 is changed, thereby driving the skeleton to run.

[0073] The top view of the adjustment platform 22 is a circular structure. A positioning boss 221 is provided on the outer circumference of the platform, which engages with the adjustment gear ring 35. A central hole 225 is provided on the circular plane, which connects to the support rod 5 in the spray assembly. A first boss 222 is provided along the edge of the central hole, and a second boss 223 is provided at a predetermined distance from the first boss 222. A sliding groove 224 is formed between the first boss 222 and the second boss 223, allowing the sliding block 2113 connected to the frame of the spray umbrella 212 to move along the sliding groove 224. The bottom surface of the sliding groove 224 is parallel to the surface of the circular plane.

[0074] In another embodiment of this application, the sliding groove 224 is a groove on a circular plane, and the bottom surface of the groove is lower than the surface of the circular plane.

The top view of the connector 33 is circular. A through hole 34 is opened in the middle of the circle of the connector 33. The cross-section of the through hole is a plane with a locking boss 331. The locking boss 331 is used to engage with the slot 51 of the support rod 5 in the spray assembly to fix the position of the adjustment mechanism 3.

[0077] The adjusting toothed ring 35 includes a rotating ring 31, an upper tooth 32, and a lower tooth 36. The rotating ring 31 is a hollow cylindrical structure. The upper tooth 32 is fixedly installed at the upper opening of the rotating ring 31 and forms a circle around the inner wall of the cylinder. The tooth tip points to the center of the circle. The upper tooth 32 is used to mesh with the drag block 2112 in the opening and closing structure 211. When the upper tooth rotates, it drives the drag block 2112 to move.

[0078] The lower tooth 36 is located at the lower port opening of the rotating ring 31. The tooth extends along the axial direction of the cylinder, and the tooth tip also points to the center of the circle, forming a circle around the inner wall of the cylinder.

[0079] A locking groove 37 is provided on the inner wall of the adjusting toothed ring 35 at a position higher than the plane of the connector 33. The locking groove 37 is used to engage with the positioning boss 221 in the adjusting platform 22 to fix the position of the adjusting platform 22.

[0080] The diagram showing the combination of the first fixing mechanism 1, the adjusting mechanism 3, and the spray adjusting mechanism 2 is as follows. Figure 11 As shown.

[0081] Adjustment control mechanism 10, such as Figure 12 , Figure 13 , Figure 14 As shown, where, Figure 12 This is a schematic diagram of the first gear structure. Figure 13 This is a schematic diagram of the second gear structure. Figure 14 This is an assembly drawing of the first gear structure and the second gear structure.

[0082] The first gear structure 101 includes a first gear 1012, a first gear shaft 1013, and a handle 1011. The handle 1011 and the first gear 1012 are located at both ends of the first gear shaft 1013, and the handle 1011 is fixed to the first gear shaft 1013. One end 1014 of the first gear shaft 1013 is movably mounted on the medicine bottle 8, and the other end of the first gear shaft 1013 extends beyond the first gear 1012. The first gear shaft 1013 has a hollow structure on the side where the first gear 1012 is located, and its cross-section is square. The first gear shaft 1013, located on the side of the handle 1011, is also a hollow structure with a circular cross-section. A second shaft 1015 is disposed within this circle, with a diameter smaller than the diameter of the hollow circular structure. The second shaft 1015 is fitted into the hollow space of the first gear shaft 1013; that is, the first gear shaft 1013 is fitted onto the outer surface of the second shaft 1015. The second shaft 1015 can move vertically along the axial direction of the first gear shaft 1013 and rotate radially along the first gear shaft 1013. One end of the second shaft 1015 is movably mounted on a medicine bottle.

[0083] The medicine bottle has a mounting hole for a second shaft, but the mounting hole does not penetrate the bottle wall.

[0084] The second gear structure includes a second gear 1021 and a second gear shaft 1022. The cross-section of the second gear shaft 1022 is square and is used to fit into the hollow of the first gear shaft 1013. The second gear 1021 is installed at the top of the second gear shaft 1022 and is used to mesh with the lower tooth 36 of the adjusting gear ring 35.

[0085] The structure of the fourth fixing mechanism 7, such as Figure 15 As shown. The fourth fixing mechanism 7 is a circular or semi-circular structure. Two holes are formed in the circular structure. The edge of the third hole 74 is used for fixed connection with the support rod 5. The fourth hole 71 is located along the fan-shaped surface of the circular structure and close to the circumference, near the edge 75 of the circular structure, forming a fan-shaped structure used to define the operating position of the second fixing mechanism 9 outside the nasal cavity. Several fixing positions 73 are provided around the edge 75 for fixing the second fixing mechanism 9 outside the nasal cavity. The fourth hole 71 in the fourth fixing mechanism 7 has the same shape as the second hole 62 in the third fixing mechanism 6.

[0086] An internal tooth 72 is provided on the inner wall of the edge 75 facing the fourth hole 71. The internal tooth 72 is used to mesh with the first gear 1012. The inner diameter of the fourth hole 71 is related to the outer diameter of the first gear 1012. After the first gear 1012 meshes with the internal tooth 72, it can move along the fourth hole 71 when rotating.

[0087] like Figure 16As shown, the fourth hole 71 in the fourth fixing mechanism 7 corresponds to the second hole 62 in the third fixing mechanism 6, and is used to pass through the first gear structure and the second gear structure in the adjustment control mechanism 10. The bottom surface of the second gear is higher than the upper surface of the third fixing mechanism 6, and the first gear meshes with the internal teeth 72.

[0088] The second fixing mechanism 9 includes several fixing sub-mechanisms, each with the same structure, including: a first connecting rod 94, a second connecting rod 93, and a pressure rod 92. One end of the pressure rod 92 is connected to the other end of the first connecting rod 94. One end of the second connecting rod 93 is rotatably connected to a position of the pressure rod 92 near the first connecting rod 94. The other end of the pressure rod 92 is fixedly provided with a pressure head 91. Near the pressure head, the pressure rod 92 has a certain curvature, so that when one end of the pressure rod 92 is rotated, the pressure head 91 rotates and presses against the outside of the nasal cavity.

[0089] One end of the first connecting rod 94 is fixedly installed at the fixed position 73 in the fourth fixing mechanism 7, and one end of the second connecting rod 93 is fixedly installed at the fixed position 64 in the third fixing mechanism 6. The other end of the first connecting rod 94 is connected to one end of the pressure rod 92, and the other end of the second connecting rod 93 is rotatably connected to the pressure rod 92. A pressure head 91 is fixedly installed at the other end of the pressure rod 92. The pressure rod 92 has a certain curvature at the end near the pressure head 91, so that when the pressure rod 92 rotates, it drives the pressure head 91 to rotate, thereby pressing the pressure head 91 against the outside of the nasal cavity and fixing the position of the nasal spray device to the nasal cavity.

[0090] A rack may or may not be provided along the inner edge of the second hole 62.

[0091] In one specific embodiment of this application, such as Figure 17 As shown, at the bottom of the medicine bottle 8, there is a box 12 for placing the power supply and / or nebulization control. A power cord 1201 is led out from the side of the box to the support rod 5 and connected to the nebulizer along the support rod 5. The medicine is sprayed out from the nebulization outlet 4.

[0092] This application discloses a nasal spray device for otolaryngology, such as... Figure 18 As shown, its working principle is as follows: The first fixing mechanism 1 fixes the position of the spray device inside the nasal cavity and directs the spray outlet 4 toward the lesion.

[0093] Under normal circumstances, the second gear 1021 meshes with the tooth 36, and the first gear 1012 disengages from the internal tooth 72 in the fourth fixing mechanism 7. When the handle 1011 is rotated, the second gear 1021 drives the tooth 36 to rotate. The rotation of the tooth 36 drives the rotating ring 31 in the adjusting ring 35 to rotate. The rotation of the rotating ring 31 drives the upper tooth 32 to rotate. When the upper tooth 32 rotates, it drives the drag block 2112 to move. The movement of the drag block 2112 drives the sliding block 2113 to move along the sliding groove 224, thereby causing the skeleton to contract or expand, and thus controlling the amount of medicine dispensed from the atomizing outlet 4.

[0094] Under the action of external force, the handle 1011 pushes the first gear shaft 1013 to move downward along the second shaft 1015, causing the first gear 1012 to mesh with the internal teeth 72 in the fourth fixing mechanism 7, and the second gear 1021 to disengage from the teeth 36; when the handle 1011 is rotated, the first gear 1012 moves along the internal teeth 72, causing the pressure rod 92 to rotate along the end of the second connecting rod 93, thereby adjusting the pressure head 91 to fit tightly against the outside of the nasal cavity, achieving positioning outside the nasal cavity.
