Description

Technical Field

[0001] This disclosure relates to the field of inhalers, and more particularly to a fluid distribution structure for manual operation, a spray device, a spray kit, and a nasal spray kit. Background Technology

[0002] Inhaler devices, as medical devices for inhalation or nasal administration, are widely used in the treatment of respiratory diseases, vaccination, hormone replacement therapy, and drug delivery for central nervous system diseases. Compared with oral and injectable administration, inhalation offers potential advantages such as avoiding the first-pass effect in the liver, rapid onset of action, and higher patient compliance. The core function of an inhaler device is to transform liquid or suspension drugs into a spray or aerosol suitable for mucosal absorption; its performance directly affects the accuracy, safety, and effectiveness of drug delivery.

[0003] However, most manual spray devices currently on the market use axial pressing, meaning the reservoir and nozzle are coaxially aligned, and users use the relative movement of their thumb and index / middle finger to spray. However, this method has at least the following drawbacks: 1. The direction of force coincides with the spray direction; the user's hand contraction during pressing can easily cause axial displacement or lateral wobbling of the entire device. 2. The axial pressing design is not ergonomic; overcoming the spring resistance between the reservoir and nozzle is necessary when pressing axially. These issues will affect the spray effect and the user experience for those with weaker hand strength. Summary of the Invention

[0004] The purpose of this disclosure is to provide a manually driven fluid dispensing structure, spray device, spray kit, and nasal spray kit.

[0005] In a first aspect, this disclosure provides a manually driven fluid dispensing structure for use with a reservoir, comprising: An intermediate having a receiving space for accommodating the reservoir; A nozzle assembly, the nozzle assembly including a nozzle body and at least one lateral pressing element, one end of the lateral pressing element being connected to the nozzle body; The intermediate body is movably disposed on the nozzle body along a first direction. The free end of the lateral pressing element has an extension. The intermediate body has a protrusion. When the extension moves toward the receiving space, the extension abuts against the protrusion. The intermediate body moves toward the nozzle body to compress the reservoir and pump out the liquid.

[0006] This disclosure provides a manually driven fluid distribution structure, including an intermediate body and a nozzle assembly, which are arranged along a first direction. The nozzle assembly includes a nozzle body and at least one lateral pressing element, one end of which is connected to the nozzle body. When an external force is applied to the free end of the lateral pressing element, the lateral pressing element moves toward the receiving space of the intermediate body. At this time, the extension of the lateral pressing element abuts against the protrusion of the intermediate body. The extension and the protrusion cooperate with each other, and the protrusion is squeezed upward by the force of the extension, that is, it moves axially along the first direction, thus realizing the movement of the intermediate body toward the nozzle body. Therefore, during use, users only need to replace the reservoir with a different one and then use the reservoir in conjunction with the manually operated fluid distribution structure. The lateral pressing operation changes the direction of the driving force from axial to lateral, effectively avoiding axial displacement during pressing that could cause the nozzle body to shake and injure the nasal mucosa. It also ensures the stability of the nozzle body's positioning within the nasal cavity. Furthermore, the lateral pressing element conforms more to the natural grip of the human hand, making operation more convenient and effortless for users. Simultaneously, the lateral pressing force is converted into axial movement, i.e., axial movement between the intermediate body and the nozzle body. Therefore, by controlling the magnitude of the lateral force, the stroke length of the axial movement between the intermediate body and the nozzle body is effectively guaranteed, ensuring sufficient pressing pressure on the reservoir and ensuring that a sufficient dose of medication is dispensed from it.

[0007] In some specific embodiments, the nozzle body and the lateral pressing element are an integral structure, and at least the lateral pressing element is an elastic material with elastic deformation; or one end of the lateral pressing element is pivotally connected to the nozzle body.

[0008] In some specific embodiments, there are two lateral pressing elements, which are symmetrically arranged with respect to the first direction.

[0009] In some specific embodiments, the intermediate body includes a body and a first connecting portion. The first connecting portion is disposed on the body along a first direction. The first connecting portion includes two guide members, which are spaced apart along a second direction. The first direction is perpendicular to the second direction. The space between the two guide members is used to accommodate the nozzle body. A clearance area is formed between the sidewalls of the two guide members, which is used to accommodate the lateral pressing element.

[0010] In some specific embodiments, the body located in the avoidance area is formed with an inclined surface, which is used to avoid the movement trajectory of the lateral pressing element when the lateral pressing element moves.

[0011] In some specific embodiments, the intermediate body further includes a baffle disposed on the body, with a gap between the baffle and the body along the second direction, the gap being used to constrain the extension of the lateral pressing element, wherein the extension is always in contact with the protrusion when the lateral pressing element rotates.

[0012] In some specific embodiments, the inner wall of the intermediate body is provided with a buckle, which is used to fix it relative to the liquid reservoir.

[0013] In a second aspect, this disclosure provides a spraying device, including a reservoir and a fluid dispensing structure for manual operation as described in the first aspect, the fluid dispensing structure for manual operation being detachably mounted on the reservoir. The liquid reservoir includes a medicine bottle and a retractable pump body. The pump body is connected to the medicine bottle and has a liquid inlet and an outlet. When the pump body moves, the outlet moves closer to or further away from the inlet. The inlet extends into the medicine bottle, which is detachably connected to the intermediate body. The outlet of the pump body extends into the interior of the nozzle body, which has an opening. The outlet is correspondingly positioned to the opening, and the fluid ejected from the outlet of the pump body is ejected through the opening.

[0014] By designing the fluid dispensing structure for manual operation and the reservoir to be detachably connected, the fluid dispensing structure for manual operation can be reused. When different drugs are needed to treat different diseases, only the reservoir storing the different drugs needs to be replaced, reducing the user's medication costs.

[0015] In some specific embodiments, the pump body includes a fixed member, a movable member, and an elastic member. The fixed member is connected to the intermediate body and the medicine bottle. The movable member is connected to the nozzle body. The movable member is movably disposed on the fixed member along the first direction. The elastic member is located in the space between the fixed member and the movable member and is used to store elastic potential energy. When the lateral pressing element is pressed inward by an external force, the intermediate body moves toward the nozzle body, the movable member and the fixed member move closer to each other, the elastic member in the pump body is compressed, and the medicine is sprayed out from the medicine bottle through the outlet of the pump body. The elastic member is compressed along the first direction and stores the elastic potential energy, which is used to reset the movable member relative to the fixed member.

[0016] Thirdly, this disclosure provides a spray kit including a housing and the spray device described in the second aspect, the housing being detachably connected to the intermediate body, the housing being at least partially fitted onto the outer surface of the nozzle assembly and the outer surface of the intermediate body, and the housing at least covering the nozzle body of the nozzle assembly.

[0017] Users typically carry the spray device in a bag or pocket. The outer casing covers the outer surface of the nozzle assembly's nozzle body. When the spray device is not in use, the casing forms a physical barrier, effectively preventing airborne dust, microorganisms, or contaminants from adhering to the nozzle body's outer surface. This ensures the hygienic condition of the spray device during storage, transport, or disuse, significantly reducing the risk of secondary contamination during medication use. Simultaneously, the casing effectively cushions the impact of accidental drops or pressure, preventing accidental damage or breakage at the connection between the nasal spray assembly and the intermediate body. It also effectively prevents liquid leakage from the nozzle body, thereby improving the overall durability and reliability of the nasal spray kit. Furthermore, since the casing at least partially covers the outer surface of the nozzle assembly, it also effectively prevents accidental contact with the lateral pressing element on the nozzle assembly.

[0018] In some specific embodiments, the outer shell includes an outer shell extension, and the intermediate body includes two baffles, which are spaced apart along a third direction, the third direction being perpendicular to the second direction; When the housing is installed on the spray device, the housing extension is located in the gap between the two baffles to prevent the free end of the lateral pressing element from moving toward the receiving space.

[0019] Fourthly, the present disclosure provides a nasal spray kit, including a soft shell and the spray device described in the second aspect, wherein the soft shell has an installation space and the spray device is located within the installation space; The soft shell includes at least one nose support that can be inserted into the nostril. One of the at least one nose support is disposed corresponding to the liquid outlet of the pump body. The nose support disposed corresponding to the liquid outlet of the pump body has a spray nozzle and at least one air outlet. The centerline of the spray nozzle, the centerline of the pump body and the centerline of the opening of the nozzle body coincide. The air outlet is located on the periphery of the spray nozzle.

[0020] This disclosure provides a nasal spray kit. When nasal spraying is required, simply pressing the sides of the soft shell engages the lateral pressing element on the spray device, thus achieving drug spraying. Because the soft shell is entirely sealed, at least one nasal support is provided, with a spray nozzle and at least one air outlet located at this position. Therefore, when the sides of the soft shell are pressed, a certain positive airflow is generated at the air outlet around the spray nozzle. That is, the air outlet on the nasal support, in conjunction with the spray nozzle, forms a positive pressure-assisted flow field around the spray area. This airflow field effectively assists in propelling the drug mist, overcoming the resistance generated by the nasal cavity structure, and delivering the drug mist deeper into the nasal cavity. This significantly improves the deposition rate of the drug mist in the target area, i.e., targeting, reduces drug waste and dosage loss, and ensures that the drug is fully absorbed, effectively improving the therapeutic effect. Furthermore, the axial guidance provided by the nose support facilitates the hydrodynamic environment for drug mist diffusion and inhalation; in addition, the nose support is also made of soft material, which improves the tightness between the device and the nostrils and reduces the possibility of drug leakage from the edge of the nostrils.

[0021] In some specific embodiments, the soft shell includes a first shell and a second shell, the first shell is connected to the second shell, the nose support extends upward from the body of the first shell, the inner wall of the first shell is provided with a first limiting stop, the first limiting stop abuts against the nozzle body; the inner wall of the second shell is provided with a second limiting stop, the second limiting stop abuts against the liquid reservoir.

[0022] In some specific embodiments, the first limiting stop is close to the air outlet, and the first limiting stop includes at least two limiting blocks, the limiting blocks being located between two adjacent air outlets. Attached Figure Description

[0063] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0064] Furthermore, the following descriptions of the embodiments are with reference to the accompanying illustrations, which illustrate specific embodiments in which this disclosure can be implemented. Directional terms used in this disclosure, such as "up," "down," "front," "rear," "left," "right," "inner," "outer," and "side," are merely directional references to the accompanying illustrations. Therefore, the directional terms used are for better and clearer explanation and understanding of this disclosure, and are not intended to indicate or imply that the referred device or element must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this disclosure.

[0065] It should be noted that, in order to more clearly describe the respiration-triggered aerosol device provided in this disclosure, the direction of the rotational center axis of an object such as a column or tube is defined as the axial direction; the circumferential direction is the direction around the axis of the object (perpendicular to the axis and also perpendicular to the cross-sectional radius); and the radial direction is the direction along the diameter or radius. It is worth noting that the term "end" appearing in terms such as "one end," "the other end," "first end," "second end," "initial end," "end point," "both ends," "free end," "upper end," and "lower end" is not limited to a tip, endpoint, or end face, but also includes a portion extending axially and / or radially from the tip, endpoint, or end face on the element to which the tip, endpoint, or end face belongs. Unless otherwise defined, all technical and scientific terms used in this disclosure have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The conventional terminology used in this specification is for the purpose of describing particular embodiments only and should not be construed as limiting the disclosure.

[0066] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0067] A spray device is a mechanical structure that consumes mechanical energy to break down, disperse, and directionally transport liquid or powdered solid media through a specific structure (such as a nozzle and pump body on a liquid reservoir).

[0068] like Figure 1 and Figure 2 As shown, in a first aspect, an embodiment of this disclosure provides a manually driven fluid dispensing structure 1 for use with a reservoir 2, comprising: an intermediate body 11 having a receiving space 117 for accommodating the reservoir 2; and a nozzle assembly 12 including a nozzle body 121 and at least one lateral pressing element 122. The number of lateral pressing elements 122 shown in the figure is merely an example; for example, there may be one or two lateral pressing elements 122. Two lateral pressing elements 122 can be used when the user presses... When pressing, it can better ensure the balance of the pressing force on both sides. One end of the lateral pressing element 122 is connected to the nozzle body 121. The intermediate body 11 is movably disposed on the nozzle body 121 along the first direction. The free end 1223 of the lateral pressing element 122 has an extension 1221. The intermediate body 11 has a protrusion 111. When the extension 1221 moves toward the receiving space 117, the extension 1221 abuts against the protrusion 111, and the intermediate body 11 moves toward the nozzle body 121 to compress the liquid reservoir and pump out the liquid.

[0069] It should be noted that the fluid distribution structure 1 for manual operation provided in this disclosure includes an intermediate body 11 and a nozzle assembly 12. The intermediate body 11 and the nozzle assembly 12 are arranged along a first direction. The nozzle assembly 12 includes a nozzle body 121 and at least one lateral pressing element 122. One end of the lateral pressing element 122 is connected to the nozzle body 121. When an external force is applied to the free end 1223 of the lateral pressing element 122, the lateral pressing element 122 moves toward the receiving space 117 of the intermediate body 11. At this time, the extension 1221 of the lateral pressing element 122 abuts against the protrusion 111 of the intermediate body 11. The extension 1221 and the protrusion 111 cooperate with each other. The protrusion 111 is squeezed upward by the force of the extension 1221, that is, it moves axially along the first direction, thus realizing the movement of the intermediate body 11 toward the nozzle body 121. Therefore, during use, the user only needs to replace the reservoir 2 with a different one and then use the reservoir 2 in conjunction with the fluid distribution structure 1 for manual operation. The lateral pressing operation of the lateral pressing element 122 changes the direction of the driving force from axial to lateral, effectively avoiding axial displacement caused by the moment of pressing, which could cause the nozzle body 121 to shake and accidentally injure the nasal mucosa. At the same time, it ensures the positioning stability of the nozzle body 121 in the nasal cavity. In addition, the lateral pressing of the lateral pressing element 122 is more in line with the natural gripping habits of the human hand, making the operation more convenient and effortless for the user. At the same time, the lateral pressing force is converted into axial movement, that is, axial movement between the intermediate body 11 and the nozzle body 121. Therefore, by controlling the magnitude of the lateral force, the stroke length of the axial movement between the intermediate body 11 and the nozzle body 121 is effectively ensured, thereby ensuring that the pressing force on the reservoir 2 is sufficient and that a sufficient dose of medicine is sprayed from the reservoir 2.

[0070] Continue to refer to Figure 2 , Figure 2 In one embodiment of the fluid distribution structure 1 for manual operation, one end 1222 of the lateral pressing element 122 is pivotally connected to the nozzle body 121. A rotating shaft 1212 pivotally connected to one end 1222 of the lateral pressing element 122 is formed on the nozzle body 121. The other end is a free end 1223, which is the position where the user presses with their thumb or index finger. When the user manually presses the free end 1223, the extension 1221 moves toward the receiving space 117. Figure 2 To ensure the smooth movement of the lateral pressing element 122, two extensions 1221 of the free end 1223 are provided to guarantee the stability of the movement of the lateral pressing element 122. In the figure, there are two lateral pressing elements 122, which are symmetrically arranged relative to the first direction, further ensuring the balance of pressing forces on both sides.

[0071] like Figure 3 As shown, Figure 3In another embodiment of the fluid distribution structure 1 for manual operation, one end 1222 of the lateral pressing element 122 is fixedly connected to the nozzle, that is, the nozzle body 121 and the lateral pressing element 122 are an integral structure, and the other end is a free end 1223, which is the position where the user presses with their thumb or forefinger. When the free end 1223 is pressed, since at least the lateral pressing element 122 is made of an elastic material with elastic deformation, the extension 1221 moves toward the receiving space 117. In the figure, there are two lateral pressing elements 122, which are symmetrically arranged with respect to the first direction, which better ensures the balance of pressing force on both sides.

[0072] To clearly understand the intermediate 11 of the manually driven fluid distribution structure 1 provided in the embodiments of this disclosure, such as Figure 4 As shown, Figure 4 This is a three-dimensional structural diagram of the intermediate body 11. Specifically, the intermediate body 11 includes a body 112 and a first connecting portion 113. The first connecting portion 113 is disposed on the body 112 along a first direction. The first connecting portion 113 includes two guide members 1131, which are spaced apart along a second direction. The first direction is perpendicular to the second direction. The space between the two guide members 1131 is used to accommodate the nozzle body 121. During assembly, the nozzle body 121 of the nozzle assembly 12 is inserted into the first connecting portion 113 on the intermediate body 11 along the first direction. The nozzle body 121 is clamped or guided by the two guide members 1131 located on both sides. Since the guide members 1131 are spaced apart along the second direction, which is perpendicular to the first direction (i.e., radially), they provide radial limiting for the nozzle body 121, ensuring precise alignment between the nozzle body 121 and the axis of the intermediate body 11. That is, the movement trajectory will not deviate during the relative movement of the intermediate body 11 and the nozzle body 121. A clearance area 1131a is formed between the sidewalls of the two guide members 1131, which is used to accommodate the lateral pressing element 122. When the user applies a lateral force to the lateral pressing element 122, i.e., along the second direction, the lateral pressing element 122 begins to move towards the axis. The clearance area 1131a provides movement space for the lateral pressing element 122. When the lateral pressing element 122 moves along the second direction, it is accommodated by the clearance area 1131a, thus avoiding movement interference.

[0073] Furthermore, the body 112 located in the avoidance area 1131a has an inclined surface 1121. When the lateral pressing element 122 moves, the inclined surface 1121 is used to avoid the movement trajectory of the lateral pressing element 122. The inclined surface 1121 is provided in the avoidance area 1131a of the intermediate body 11 body 112 to avoid the complex movement trajectory of the lateral pressing element 122 during the driving process, that is, to avoid friction, scraping or jamming interference between the lateral pressing element 122 and the structure of the intermediate body 11 body 112 during movement; therefore, the smoothness and stability of the movement of the lateral pressing element 122 are greatly improved, ensuring the integrity of each pressing stroke, thereby improving the stability of the entire fluid distribution structure 1 for manual drive.

[0074] Continue to refer to Figure 4 The intermediate body 11 also includes a second connecting portion 114, which is disposed opposite to the first connecting portion 113 along a first direction. The second connecting portion 114 includes two limiting members 1141, which are spaced apart along a third direction, perpendicular to the second direction. The space between the two limiting members 1141 is used to accommodate the liquid storage tank. Since the arrangement direction of the limiting members 1141, i.e., the third direction, is perpendicular to the movement direction of the lateral pressing element 122, i.e., the second direction, there is no spatial interference with the lateral pressing element 122, resulting in a more compact structure for the intermediate body 11. The outer surfaces of the two limiting parts 1141 are provided with anti-slip strips 11411, which facilitates the user's assembly and disassembly when quickly assembling and disassembling the liquid storage tank. The smooth outer surface of the liquid storage tank will not make it difficult to assemble and disassemble. The entire intermediate body 11 realizes bidirectional precise and quick insertion and removal of the liquid storage tank and the nozzle assembly 12, which greatly facilitates the user to replace the liquid storage tank and maintain the device.

[0075] like Figure 5As shown, the intermediate body 11 also includes a baffle 115, which is disposed on the body 112. Along the second direction, there is a gap between the baffle 115 and the limiting member 1141. The gap is used to constrain the extension 1221 of the lateral pressing element 122. When the lateral pressing element 122 rotates, the extension 1221 is always in contact with the protrusion 111. The gap formed by the baffle 115 and the limiting member 1141 provides precise constraint and guidance for the extension 1221 of the lateral pressing element 122, ensuring that the extension 1221 can always maintain contact with the protrusion 111 during rotation. This prevents the extension 1221 of the lateral pressing element 122 from displacing or shaking when pressing the lateral pressing element 122, thereby ensuring the smoothness of the lateral rotation pressing transmission. When the fluid distribution structure 1 for manual operation provided in this embodiment is used in conjunction with the reservoir 2, a nozzle 27 is provided inside the nozzle body 121 of the fluid distribution structure 1 for manual operation. There are at least two ways to configure the nozzle 27: Method 1: The nozzle 27 is connected to the nozzle body 121 in the nozzle assembly 12, and the reservoir 2 does not include the nozzle 27; Method 2: The nozzle 27 is connected to the reservoir 2, and when needed, the reservoir 2 can be directly connected to the fluid distribution structure 1 for manual operation.

[0076] In addition, the inner wall of the intermediate body 11 is provided with a buckle 116 for fixing it relative to the reservoir 2. The buckle 116 on the inner wall of the intermediate body 11 can quickly fix it relative to the reservoir 2, which is more user-friendly and convenient for replacement.

[0077] As can be seen from the above description, the fluid distribution structure 1 for manual operation provided in this disclosure embodiment has at least two structures: such as Figure 2 As shown, the nozzle body 121 is pivotally connected to the lateral pressing element 122; as Figure 3 As shown, the nozzle body 121 and the lateral pressing element 122 are an integral structure.

[0078] like Figures 6-8 As shown, in a second aspect, an embodiment of this disclosure provides a spraying device, including a reservoir 2 and a fluid distribution structure 1 for manual operation as described in any of the first aspects. Figure 6 The fluid distribution structure 1 for manual operation shown in Figure 7 is illustrated with an example of the nozzle body 121 being pivotally connected to the lateral pressing element 122. Of course, this can be adjusted according to the actual situation. Figure 6 The nozzle body 121 and the lateral pressing element 122 in the fluid distribution structure 1 for manual drive shown in Figure 7 can also be an integral structure.

[0079] Continue to refer to Figure 6 , Figure 7A and Figure 7BA fluid distribution structure 1 for manual operation is detachably mounted on a reservoir 2; the reservoir 2 is mounted to an intermediate body 11 along a first direction, the reservoir 2 enters from the bottom of the intermediate body 11 and then extends from the top of the intermediate body 11; the reservoir 2 includes a medicine bottle 21 and a pump body connected to the medicine bottle 21, the pump body being telescopically movable, the pump body having an outlet 24 and an inlet 26, when the pump body moves, the outlet 24 moves closer to or further away from the inlet 26, the inlet 26 being located in the medicine bottle 21, the medicine bottle 21 being detachably connected to the intermediate body 11, the outlet 24 of the pump body extending into the interior of a nozzle body 121, the nozzle body 121 having an opening 1211, the outlet 24 being correspondingly arranged with the opening 1211, and the fluid ejected from the outlet 24 of the pump body being ejected from the opening 1211.

[0080] contrast Figure 7A and Figure 7B The specific difference is that, Figure 7A The central nozzle 27 is mounted on the top of the pump body of the medicine bottle 21 and is an integral structure with the liquid reservoir 2; Figure 7B The central nozzle 27 is not an integral part of the liquid reservoir 2; please refer to the following for details. Figure 5 As shown, the nozzle 27 is located inside the nozzle body 121, and the nozzle 27 and the nozzle body 121 are an integral structure.

[0081] Specifically, such as Figure 8 As shown, the pump body includes a fixed member 22, a movable member 23, and an elastic member 25. The movable member 23 is movably disposed on the fixed member 22 along a first direction. The fixed member 22 is connected to the medicine bottle 21 and also to the intermediate body 11. The movable member 23 is connected to the nozzle body 121. The elastic member 25 is located in the space between the fixed member 22 and the movable member 23 and is used to store elastic potential energy. When the movable member 23 and the fixed member 22 are relatively close, the elastic member 25 is compressed. When the lateral pressing element 122 is pressed inward by an external force, the intermediate body 11 moves toward the nozzle body 121, the movable member 23 and the fixed member 22 move closer to each other, the elastic member 25 in the pump body is compressed, and the medicine is drawn from the medicine bottle 21 through the inlet 26 of the pump body and sprayed out from the outlet 24. The elastic member 25 is compressed along the first direction and stores elastic potential energy, which is used to reset the movable member 23 relative to the fixed member 22.

[0082] The nozzle body 121 is fixed to the movable part 23 of the pump body, the fixed part 22 of the pump body is fixed to the medicine bottle 21, and the intermediate body 11 is fixed to the medicine bottle 21. That is to say, the intermediate body 11 is fixed to the fixed part 22 of the pump body. The action of the lateral pressing element 122 causes the nozzle body 121 and the intermediate body 11 to move towards each other, realizing the opposite movement of the movable part 23 of the pump body and the fixed part 22 of the pump body. The elastic element 25 in the pump body is compressed, so that the pump body pumps the liquid out of the medicine bottle 21. Because the pump body has the elastic element 25, the elastic element 25 has elastic potential energy during the compression process of the pump body. When the pressing force is released, the elastic potential energy is released, and the movable part 23 of the pump body moves in the opposite direction to the fixed part 22, that is, the movable part 23 of the pump body resets, which causes the intermediate body 11 and the nozzle assembly 12 to also move in the opposite direction, that is, the nozzle body 121, so that the lateral pressing element 122 also resets.

[0083] By designing the fluid distribution structure 1 for manual operation and the reservoir 2 as detachable, the fluid distribution structure 1 for manual operation can be reused. When different drugs are needed to treat different diseases, only the reservoir 2 storing different drugs needs to be replaced, which reduces the user's medication costs.

[0084] Continue to refer to Figure 8 The pump body has an elastic element 25 (shown as a dashed line in the figure), which is disposed within the pump body. Specifically, the reservoir 2 is an integrated structure for storing the liquid medicine. Specifically, the pump body, as the core structure, is tightly and non-removably fixed to the mouth of the medicine bottle 21 by a sealing gasket and a cap, ensuring the sealed storage of the liquid medicine. The inlet 26 of the pump body is axially inserted into the bottom of the medicine bottle 21, guiding the liquid medicine from the bottom of the medicine bottle 21 into the pump body. When the lateral pressing element 122 is pressed inward by an external force, the intermediate body 11 moves toward the nozzle body 121, the pump body is compressed, and the movable part 23 in the pump body moves toward the fixed part 25. At this time, the elastic element 25 is compressed. When the pump body is compressed, it pumps the liquid medicine in the medicine bottle 21 to the outlet 24 of the pump body. The reservoir 2 also includes a nozzle 27, which is fitted onto the outlet 24 of the pump body and has holes through which the liquid medicine flows out.

[0085] The following is a detailed analysis of a spraying device provided in the embodiments of this disclosure.

[0086] The fluid distribution structure 1 for manual drive in a spraying device provided in this disclosure has at least two structures: structure one, the nozzle body 121 is pivotally connected to the lateral pressing element 122; structure two, the nozzle body 121 and the lateral pressing element 122 are an integral structure.

[0087] When the fluid distribution structure 1 used for manual operation adopts structure one, the nozzle body 121 is pivotally connected to the lateral pressing element 122, such as Figures 9-13 As shown, Figure 9 A top view of a fluid distribution structure 1 for manual operation used in a spraying device provided in an embodiment of this disclosure. Figure 1 ;at this time Figure 9 The lateral pressing element 122 was not pressed. To clearly see the internal structure of the spraying device provided in this embodiment, Figure 9 Sections were taken at points AA and BB. For example... Figure 10 As shown, Figure 10 for Figure 9 In the cross-sectional view corresponding to AA, the free end 1223 of the lateral pressing element 122 has an extension 1221, and the intermediate body 11 has a protrusion 111. When the extension 1221 moves toward the receiving space 117, as... Figure 11 As shown, the extension 1221 abuts against the protrusion 111, and the extension 1221 applies an upward force to the protrusion 111, causing the intermediate body 11 to move toward the nozzle body 121. Figure 12 As shown, Figure 12 for Figure 9 The corresponding cross-sectional view at BB: One end 1222 of the lateral pressing element 122 is pivotally connected to the nozzle body 121. A rotating shaft 1212 is formed on the nozzle body 121, which is pivotally connected to one end 1222 of the lateral pressing element 122, so that the lateral pressing element can rotate around the rotating shaft 1212. At the same time, through the cooperation between the extension 1221 on the lateral pressing element and the protrusion 111 on the intermediate part, the inward movement of the lateral pressing element is converted into the axial upward movement of the intermediate body 11, such as... Figure 13 As shown, the reservoir 2 can be fixed to the intermediate component by the buckle 116 on the intermediate component.

[0088] When the lateral pressing element 122 is pressed continuously, the spray device structure provided in this embodiment of the present disclosure is as follows: Figures 15-17 ,like Figure 15 As shown, at this time, the lateral pressing element 122 has started to press. The nozzle 27 of the liquid reservoir 2 is fixed on the nozzle body 121. When the lateral pressing element 122 is pressed, the nozzle body 121 remains stationary, and the intermediate body 11 moves upward. Therefore, the pump head 23 and the pump body on the axial pressing spray device will move axially closer to each other, so that the liquid is sprayed from the medicine bottle 21 through the nozzle 27 and through the top of the nozzle into the human body, such as the nose or mouth, thus completing the entire spraying process.

[0089] like Figure 18 As shown, Figure 18This is a three-dimensional structural schematic diagram of a spraying device provided in an embodiment of the present disclosure from another angle; the intermediate body 11 also includes a baffle 115, which is disposed on the body 112 and has a gap between the baffle 115 and the limiting member 1141. The gap is used to constrain the extension 1221 of the lateral pressing element 122. When the lateral pressing element 122 rotates, the extension 1221 is always in contact with the protrusion 111.

[0090] When the fluid distribution structure 1 used for manual drive adopts structure 2, such as Figures 19-25 As shown, the nozzle body 121 and the lateral pressing element 122 are an integral structure, and everything else is the same as in Structure 1. The specific movement process and structure will not be described in detail here. Figures 19-22 The lateral pressing element 122 has not yet been pressed; Figures 23-25 This is a schematic diagram of the structure after pressing the lateral pressing element 122.

[0091] like Figure 26 -like Figure 32 As shown, in a third aspect, an embodiment of this disclosure provides a spray kit, including a housing 3 and a spray device of the second aspect. The housing 3 is detachably connected to an intermediate body 11. The housing 3 is at least partially fitted onto the outer surface of the nozzle assembly 12 and the outer surface of the intermediate body 11, and the housing 3 at least covers the nozzle body 121 of the nozzle assembly 12. When the housing 3 is fitted onto the outer surface of the nozzle assembly 12, the housing extension 32 cooperates with the baffles 115 of the intermediate body 11. The area between the two baffles 115 is used to accommodate the housing extension 32, and a limiting relationship is formed between the housing extension 32 and the two baffles 115.

[0092] It should be noted that users typically carry the spray device in a bag or pocket. The outer shell 3, fitted over the nozzle body 121 of the nozzle assembly 12, forms a physical barrier when the spray device is not in use. This effectively prevents dust, microorganisms, or contaminants from adhering to the outer surface of the nozzle body 121, ensuring the hygiene of the spray device during storage, carrying, or disuse, and greatly reducing the risk of secondary contamination during medication use. Simultaneously, the outer shell 3 effectively cushions the impact of accidental drops or pressure, preventing accidental damage or breakage at the connection between the nasal spray assembly and the intermediate body 11. It also effectively prevents liquid leakage from the nozzle body 121 of the nozzle assembly 12, thereby improving the durability and reliability of the entire nasal spray kit. Furthermore, since the outer shell 3 is at least partially fitted over the outer surface of the nozzle assembly 12, it also effectively prevents accidental contact with the lateral pressing element 122 on the nozzle assembly 12.

[0093] For details, please refer to [link / reference]. Figure 26The outer shell 3 is provided with a snap fastener 31, which cooperates with the outer side of the intermediate body 11 to fix the outer shell 3 onto the intermediate body 11, making it difficult to fall off. The outer shell 3 can play a role in dust prevention and protection.

[0094] like Figure 27 As shown, Figure 27 This is a top view after the outer casing 3 is installed. To clearly understand the nasal spray kit provided in the embodiments of this disclosure, in Figure 27 Sectional view at MM and NN. Figure 28 For the corresponding Figure 27 A cross-sectional view at MM, from Figure 28 It can be determined that the outer casing 3 is fitted onto the outer surface of the spraying device, and in order to ensure the relative fixation of the outer casing 3 and the spraying device, a snap-fit ​​buckle 31 is provided on the inner wall of the outer casing 3; please refer to the following for details. Figure 29 The snap-fit ​​31 portion of the outer shell 3 abuts against the bottom side of the intermediate body 11 to restrict the movement of the outer shell 3.

[0095] Please refer to the above. Figures 30-32 The outer casing 3 is installed on the spray device, that is, the outer casing 3 at least partially covers the fluid distribution structure 1 for manual drive. The intermediate body 11 includes two baffles 115, which are spaced apart along a third direction. When the outer casing 3 is installed on the spray device, the outer casing extension 32 of the outer casing 3 is located between the two baffles 115 of the intermediate body 11. The two baffles 115 are used to restrict the axial rotation of the outer casing extension 32, thereby restricting the movement of the outer casing 3. At the same time, since the outer casing extension 32 is located between the two baffles 115 of the intermediate body 11, when the user accidentally presses the lateral pressing element 122, the outer casing extension 32 prevents the lateral pressing element 122 from moving closer to each other. That is to say, due to the presence of the outer casing extension 32, when the lateral pressing element 122 is pressed and moves towards the center, the outer casing extension 32 blocks its movement path, effectively solving the problem of accidentally spraying the lateral pressing element 122.

[0096] like Figures 33-39 As shown, in a fourth aspect, an embodiment of this disclosure provides a nasal spray kit, which includes a soft shell 4 and a spray device of the second aspect, the soft shell 4 having an installation space and the spray device being located within the installation space; The soft shell 4 includes at least one nasal support that can be inserted into the nostril. For example, when the soft shell 4 has one nose support, the nose support 411b is correspondingly arranged with the pump body. The nose support 411b corresponding to the pump body has a liquid nozzle 4111 and at least one air outlet 4112. The axis of the liquid nozzle 4111, the axis of the pump body, and the axis of the opening 1211 of the nozzle body 121 coincide. The air outlet 4112 is located on the periphery of the liquid nozzle 4111. For example, when the soft shell 4 has two nose supports, one of the two nose supports 411b is correspondingly arranged with the pump body. The nose support 411b corresponding to the pump body has a liquid nozzle 4111 and at least one air outlet 4112. The axis of the liquid nozzle 4111, the axis of the pump body, and the axis of the opening 1211 of the nozzle body 121 coincide. The air outlet 4112 is located on the periphery of the liquid nozzle 4111. The other nose support 411a of the two nose supports is blocked. Because the left and right nasal cavities are interconnected, when the soft shell 3 is pressed, the positive pressure airflow acts on one nasal cavity, and the airflow will escape from the other nasal cavity, which will affect the treatment effect. Therefore, another closed nasal support 411a needs to be set on the soft shell 3 to block the other nasal cavity. The purpose of the nasal support is to open the nasal cavity inlet so that the liquid sprayed from the nozzle can enter the nasal cavity better.

[0097] When nasal spraying is required, simply press both sides of the soft shell 4. This lateral pressing of the soft shell 4 will press it against the lateral pressing element 122 on the spray device, thus achieving drug spraying. Because the soft shell 4 is entirely sealed, with a spray nozzle 4111 and at least one air outlet 4112 located only at one of the two nasal supports 411b, pressing both sides of the soft shell 4 generates a certain positive airflow at the air outlet 4112 around the spray nozzle 4111. That is, the air outlet 4112 on the nasal support, in conjunction with the spray nozzle 4111, forms a positive pressure-assisted flow field around the drug spray area. This airflow field effectively assists in propelling the drug mist, overcoming the resistance generated by the nasal cavity structure, and delivering the drug mist deeper into the nasal cavity. This significantly improves the deposition rate of the drug mist in the target area, i.e., targeting, reducing drug waste and dosage loss, and ensuring that the drug is fully absorbed, effectively enhancing the therapeutic effect. Furthermore, the axial guidance provided by the nose support 411b facilitates the hydrodynamic environment for drug mist diffusion and inhalation; in addition, the nose support is also made of soft material, which improves the tightness between the device and the nostrils and reduces the possibility of drug leakage from the edge of the nostrils.

[0098] Continue to refer to Figure 33 and Figure 34The soft shell 4 includes a first shell 41 and a second shell 42. The first shell 41 is connected to the second shell 42. The connection between the first shell 41 and the second shell 42 is spliced ​​or welded by a first process, as long as it can be ensured that the connection between the first shell 41 and the second shell 42 is sealed except for the air vent 4112 at the nose support 411b. The two nose supports extend upward from the body 112 of the first shell 41.

[0099] like Figure 35 As shown, the nose bearing 411b with an opening 1211 is located on the central axis, that is, it coincides with the axis of the pump body and the axis of the opening 1211 of the nozzle body 121; while the central axis of the other sealing nose bearing 411a is parallel to it.

[0100] like Figure 36 As shown, the inner wall of the first housing 41 is provided with a first limiting stop 412, which abuts against the nozzle body 121; the inner wall of the second housing 42 is provided with a second limiting stop 421, which abuts against the liquid reservoir 2. The axis of the spray nozzle 4111 of the nose support 411b, the axis of the pump body, and the axis of the opening 1211 of the nozzle body 121 coincide. When the two sides of the soft shell 4 are pressed, the spray device located in the installation space inside the soft shell 4 is subjected to lateral pressure, that is, the lateral pressing element 122 is subjected to force, so that the inward movement of the lateral pressing element 122 can be converted into the axial upward movement of the middle part. The reservoir 2 can be fixed to the middle part by the buckle 116 on the middle part. The pump body of the reservoir 2 is fixed on the nozzle body 121. When the lateral pressing element 122 is subjected to force, the nozzle body 121 remains stationary. Therefore, the pump head 23 and the pump body of the reservoir 2 will axially approach each other, so that the liquid is sprayed out from the medicine bottle 21 through the top of the pump body and enters the human nose.

[0101] like Figure 37 As shown, as an example, the nose support 411b has four air outlets 4112. Of course, there can also be one, two, three, four, or five air outlets 4112. However, in order to ensure the uniformity of the air outlet area, the area of ​​each air outlet 4112 is as similar as possible, and the arrangement of each air outlet 4112 around the liquid spray nozzle 4111 is uniform, with the air outlets 4112 spaced apart around the liquid spray nozzle 4111. The first limiting stop 412 is close to the air outlet 4112. The first limiting stop 412 includes at least two limiting blocks 4121, which are located between two adjacent air outlets 4112.

[0102] like Figure 38 As shown, a second limiting stop 421 is provided at the bottom of the second housing 42, and the shape and area of ​​the second limiting stop 421 match the bottom of the medicine bottle 21 of the liquid reservoir 2.

[0103] like Figure 39As shown, when the user presses the pressing point 43 of the soft shell, the soft shell 4 deforms and squeezes the lateral pressing element 122, thereby the spray device located in the installation space inside the soft shell 4 is subjected to lateral pressure, that is, the lateral pressing element 122 is subjected to force, so that the inward movement of the lateral pressing element 122 can be converted into the axial upward movement of the middle part. The reservoir 2 can be fixed to the middle part by the buckle 116 on the middle part. The pump body of the reservoir 2 is fixed to the nozzle body 121. When the lateral pressing element 122 is subjected to force, the nozzle body 121 remains stationary. Therefore, the pump head 23 and the pump body of the reservoir 2 will axially move closer to each other, so that the liquid is sprayed from the medicine bottle 21 through the top of the pump body and enters the human nose. Figure 39 In the diagram, the solid black arrow represents the liquid sprayed from the spray nozzle 4111 of the nose support 411b, and the dashed arrow represents the spray range formed by the positive gas sprayed from the air outlet 4112 of the nose support 411b. Through the action of the air outlet 4112, the effective area of ​​the liquid sprayed from the spray nozzle 4111 is greatly increased, thereby improving the effective range of the medicine in the nasal cavity.

[0104] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this disclosure without departing from the spirit and scope of this disclosure. Therefore, if these modifications and variations of this disclosure fall within the scope of the claims of this disclosure and their equivalents, this disclosure is also intended to include these modifications and variations.
