Description

Technical Field

[0001] This invention relates to the field of auxiliary diagnostic and therapeutic devices, specifically to a nebulizer for children and its wearing device. Background Technology

[0002] Nebulization therapy, as a treatment method for pediatric respiratory diseases (such as asthma, pneumonia, bronchitis, etc.), is widely used in pediatric clinical practice due to its advantages of direct action of nebulized medication on the respiratory tract and lungs, rapid onset of action, and minimal systemic side effects. However, existing pediatric nebulizers and their wearing devices do not fully consider the differences in facial development among children of different ages (infants, toddlers, and school-aged children). The masks may not fit the facial contours, and gaps may easily appear on the sides of the nose and cheeks, resulting in a high leakage rate of nebulized gas. This leads to waste of medication and reduced local drug concentration, affecting the treatment effect. Furthermore, most existing nebulizer masks have a single direct-jet outlet structure, directly and concentratedly spraying the nebulized airflow onto the child's mouth and nose. Because children have narrow airways and sensitive cough reflexes, the high-speed, concentrated airflow can easily irritate the throat and airway, causing severe coughing and affecting the continuity of treatment.

[0003] Currently, there are similar solutions to the problems existing in nebulizer therapy for children. For example, existing patent EP3996788B1 discloses a connector for a medical tube, which has: a first part, a second part, and an inner cavity. The first part of the connector includes at least one sensor port extending through the wall of the first part into the inner cavity. The second part of the connector may have at least one electrical port configured to provide an electrical connection with at least one wire of the medical tube, and the electrical port is located on top of the second part of the connector. The first part is angled relative to the second part to form a bend. Another example is existing patent JP2025510767A, which discloses a conduit for delivering medical gases. This conduit includes an elongated tube, a sheath surrounding the elongated tube, and a pair of connectors located at opposite ends of the elongated tube. The elongated tube is formed of a breathable material to reduce condensation within the inner cavity. In use, water molecules within the inner cavity of the elongated tube dissipate by being absorbed into the breathable material, diffused through the breathable material, and desorbed into the ambient air. However, existing nebulizers and their wearable devices for children still have room for improvement in terms of wearability, treatment safety, and functional integrity. Summary of the Invention

[0004] The purpose of this invention is to provide a nebulizer for children and its wearing device, which solves the problems of poor fit of the wearing device, easy direct spray of nebulized air causing choking, cumbersome disassembly and cleaning of components, and insufficient precision of airflow adjustment. Overall, it improves the safety of treatment and enhances the compliance and treatment effect of children's nebulizer treatment.

[0005] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: a nebulization therapy wearing device for children, including a mask, the mask including a mask body, the mask body having a detachable base plate, one side of the detachable base plate located inside the mask body and the other side located outside the mask body, the detachable base plate having a detachable hole and a second tube body detachably connected thereto, the mask body having a flexible diaphragm, the flexible diaphragm dividing the space inside the mask body into upper and lower spaces. The flexible diaphragm divides the space inside the mask body into an upper nebulization chamber and a lower breathing chamber, preventing the nebulized airflow from being directly sprayed into the mouth, reducing the risk of choking. Compared to the mask body in its use state, the detachable base plate is horizontally set, that is, the plate structure of the detachable base plate is in a relatively perpendicular state to the opening surface of the mask, so that the nebulized gas entering the nebulization chamber from the diverter on the detachable base plate will not directly hit the nose, causing discomfort and increased resistance in children, and the detachable base plate is located at the bottom of the nebulization chamber, its horizontal position being the lowest. This invention uses a flexible diaphragm to divide the internal space of the mask into an atomizing chamber and a breathing chamber. This flexible diaphragm blocks the direct spray path of the atomized airflow in space. Combined with its face-fitting characteristics, it reduces the risk of choking in children, while improving the seal between the mask and the face, reducing atomized gas leakage, and increasing the utilization rate of the medication. Furthermore, the detachable structure of the disassembly and assembly base plate makes the second tube easy to disassemble and assemble, facilitating the cleaning and disinfection of each component, reducing the risk of bacterial growth. The design of the disassembly and assembly base plate also makes the atomized gas output more stable, avoiding direct spraying into the nose and exacerbating discomfort in children.

[0006] According to one embodiment of the present invention, the surface of the detachable substrate located inside the mask body is situated within the upper space of the mask body divided by the flexible diaphragm. The second tube is connected to the outlet end of the nebulizer. The flexible diaphragm has a concave portion in the middle of the opening adjacent to the mask body, allowing the flexible diaphragm to conform to the skin of the upper lip. Being made of a flexible material, it offers high comfort. When worn, the two sides of the flexible diaphragm conform to the cheeks on both sides of the nose, forming an atomization cavity between the flexible diaphragm, the face, and the mask body. Based on the detachable substrate being located in the upper space of the mask body divided by the flexible diaphragm, and the second tube being directly connected to the outlet end of the nebulizer, this utilizes the flexible material and concave structure to improve the fit and seal between the mask and the face, reduce atomized gas leakage, increase medication utilization, and alleviate facial pressure, improving comfort for children. The position of the detachable substrate, combined with the atomized airflow delivered by the second tube, prevents direct airflow from hitting the mouth and nose, reducing the risk of choking, while simultaneously allowing the atomized gas to diffuse evenly within the cavity, ensuring the medication fully acts on the respiratory tract.

[0007] According to one embodiment of the present invention, the edge of the mask has a silicone ring, and the upper part of the mask has a bendable fixing piece. The flexible properties of the silicone ring are used to conform to the facial contours of children of different ages, fill gaps in areas such as the sides of the nose, reduce the leakage rate of atomized gas, reduce waste of medicine, and ensure local drug concentration. In addition, the bendable fixing piece is used to adjust the bending angle as needed to adapt to different head circumferences and wearing postures. Combined with the fit of the flexible diaphragm, it enhances the stability of the mask and reduces facial pressure, thereby reducing children's resistance to treatment.

[0008] According to one embodiment of the present invention, the disassembly and assembly substrate has a disassembly and assembly hole outlet end provided with a flow divider connected to the disassembly and assembly substrate. The flow divider includes an air outlet head, and a connecting piece inclined to the air outlet direction is arranged around the side of the air outlet head. A spring is sleeved on the outside of the air outlet head, and the end of the connecting piece is connected to the spring. The inclined connecting piece is used to disperse the concentrated airflow delivered by the nebulizer into a diffused state, avoiding direct impact on the child's nose and airway. In addition, with the elastic buffering effect of the spring, it adaptively adjusts the airflow output pressure, weakens the airflow impact, and significantly reduces the risk of choking and discomfort. At the same time, the dispersed airflow can be evenly distributed in the nebulization chamber formed by the flexible diaphragm, increasing the contact area between the drug and the respiratory tract. Combined with the horizontal setting of the disassembly and assembly substrate, it further ensures stable airflow output, ultimately improving children's treatment compliance and drug utilization efficiency.

[0009] According to one embodiment of the present invention, the outer side of the bottom of the air outlet head is connected to the disassembly base plate via a mounting base plate. The disassembly base plate has a groove for accommodating the mounting base plate, and the surface of the mounting base plate is flush with the surface of the disassembly base plate. The surface of the mounting base plate has an inner groove. The inner groove can collect the condensed atomized drug solution and the condensed liquid in the atomization chamber. The provided inner groove is used to collect the condensed atomized drug solution and the condensed liquid in the atomization chamber, avoiding drug loss and waste, and preventing the condensate from flowing back and irritating the child's respiratory tract, ensuring drug utilization and treatment safety. Furthermore, the flush arrangement of the mounting base plate and the disassembly base plate eliminates protruding gaps at the connection point, reduces dead corners for dirt accumulation, and, combined with the detachable structure of the disassembly base plate, facilitates cleaning and disinfection, reducing the risk of bacterial growth.

[0010] According to one embodiment of the present invention, a third tube is connected to one side of the second tube via a one-way valve. An adjusting base is connected to the inlet end of the third tube. The adjusting base is hollow inside, and a bottle is connected to its bottom via a connector. The adjusting base contains a piston capable of vertical displacement. This invention uses a one-way valve to block the backflow of airflow and medication, preventing contamination. Furthermore, the vertical displacement of the piston adjusts the airflow pressure and flow rate to accommodate different children's airway resistance and treatment needs, preventing excessively strong airflow from causing choking or excessively weak airflow from affecting drug deposition. The bottle is used to store spare medication or balance air pressure. Specifically, the medication in the bottle slowly flows into the adjusting channel through the built-in channel of the connector under pressure changes in the adjusting base, mixing with the main airflow delivered by the nebulizer to form a uniform atomized mixed airflow, extending treatment time and avoiding the need to add medication midway. While the medication is in the solution, the displacement rod can be manually controlled to prevent the piston from moving upwards. Additionally, when the airflow pressure increases instantaneously, the inside of the bottle absorbs some of the pressure, acting as a buffer to prevent high-pressure airflow from directly impacting the child's airway.

[0011] According to one embodiment of the present invention, the connector has an adjustment channel communicating with a third tube body on one side. The connector is used to achieve connection and airflow diversion. The upper part of the adjustment base is open and covered with a cover plate. The middle of the cover plate has a displacement rod that can move up and down. The bottom of the displacement rod is connected to a piston. The bottom of the cover plate is connected to the piston through a swing member. A first vent pipe communicating with the adjustment channel is provided on one side. The swing member is a rod structure with one end hinged to the bottom of the cover plate and the other end hinged to the piston. The adjustment channel and the first vent pipe form an airflow passage to ensure airflow balance. The displacement rod is used to limit the vertical displacement range of the piston to prevent it from deviating. In conjunction with the hinged limiting function of the swing member, it prevents the piston from jamming or deviating, thereby improving the accuracy and stability of airflow pressure and flow regulation.

[0012] The piston moves upwards, increasing the internal volume of the regulating body and decreasing the air pressure within the cavity. This results in increased airflow and decreased pressure as the air is drawn in through the regulating channel. Conversely, when the piston moves downwards, the internal volume of the regulating body decreases, increasing the air pressure within the cavity. This leads to decreased airflow and increased pressure as the airflow is delivered to the third tube. This linear adjustment of air pressure and flow rate through volume changes caters to the airway resistance needs of children of different ages.

[0013] According to one embodiment of the present invention, a first vent pipe communicating with the regulating channel is provided on one side. The first vent pipe has at least two inlet and outlet holes, one of which is connected to a second vent pipe. An auxiliary vent hole with a diameter less than 1 cm is provided on the second vent pipe 56. A guide head is provided at the connection point between the first vent pipe and the regulating base, and the guide head has a channel for guiding the airflow. The guide head guides the airflow through the built-in channel, avoiding pressure fluctuations caused by airflow turbulence and ensuring stable airflow delivery. Furthermore, the double-hole structure of the first vent pipe forms a flow path for the main airflow and the balancing airflow. Combined with the flow-limiting effect of the small holes in the auxiliary vent hole, it balances the internal and external air pressures of the regulating base, preventing excessively high air pressure from compressing the air passage or excessively low air pressure from causing insufficient airflow.

[0014] According to one embodiment of the present invention, the cover has a side hole communicating with the interior of the upper space separated by the flexible diaphragm. The side hole is used to balance the air pressure inside and outside the atomizing chamber, to avoid the continuous input of atomized airflow causing excessive air pressure inside the chamber to compress the child's airway, to ensure smooth breathing, and at the same time to promote the formation of airflow circulation inside the atomizing chamber. Combined with the airflow dispersion effect of the diverter, it allows the atomized gas to be evenly distributed inside the chamber.

[0015] A nebulizer with a nebulizer wearing device for children, the nebulizer includes a nebulizer and a second tube connected to the outlet end of the nebulizer.

[0016] Compared with existing technologies, the beneficial effects of the present invention are as follows: The present invention improves the fit and sealing of the mask with the faces of children of different ages by using a flexible diaphragm to divide the atomizing chamber and the breathing chamber, and a flexible fixing plate with a silicone ring, thereby reducing leakage of atomized gas. With the help of the inclined connecting plate and spring of the diverter and the horizontally set disassembly plate, the atomized airflow is prevented from directly hitting the mouth and nose, reducing the risk of choking. The detachable design of the disassembly plate and the connection between the first tube, the second tube and the heater enable quick disassembly and assembly of components, which facilitates cleaning and disinfection to reduce the risk of bacterial growth. Furthermore, the heater's surrounding heating plate and support structure preheat the atomized airflow evenly, avoiding the stimulation of children's delicate airways by low-temperature airflow.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example 1: As shown in the attached figure Figure 1 -Appendix Figure 7 As shown, the nebulizer device for children includes a mask 40, which includes a body 41. The body 41 has a detachable base plate 44, with one side of the base plate 44 inside the body 41 and the other side outside. The base plate 44 has detachable holes and is detachably connected to a second tube 30. A flexible diaphragm 46 is provided inside the body 41, dividing the internal space of the body 41 into upper and lower spaces. The flexible diaphragm 46 divides the internal space of the body 41 into an upper nebulization chamber and a lower breathing chamber, preventing the nebulized airflow from being directly sprayed into the mouth and reducing the risk of choking. Compared to the mask 41 in its active state, the detachable substrate 44 is horizontally positioned, meaning its structure is perpendicular to the opening surface of the mask 41. This prevents the atomized gas from the diverter 45 on the detachable substrate 44 from directly hitting the nose, thus avoiding discomfort and increased resistance in children. Furthermore, the detachable substrate 44 is located at the bottom of the atomization chamber, its horizontal position being the lowest. The invention uses a flexible diaphragm 46 to divide the space inside the mask 41 into an atomization chamber and a breathing chamber. This flexible diaphragm 46 spatially blocks the direct jet path of the atomized gas, and its face-fitting characteristics reduce the risk of choking in children. It also improves the seal between the mask 40 and the face, reducing atomized gas leakage and increasing medication utilization. The detachable structure of the detachable substrate 44 allows for easy assembly and disassembly of the second tube 30, facilitating cleaning and disinfection of components, reducing the risk of bacterial growth. The detachable substrate 44 also ensures a more stable atomized gas output, preventing direct impact on the nose and reducing discomfort in children.

[0023] The surface of the disassembly and assembly substrate 44 located inside the cover 41 is within the upper space of the cover 41 divided by the flexible diaphragm 46. The second tube 30 is connected to the outlet end of the atomizer 10. The flexible diaphragm 46 has a concave portion in the middle of the opening adjacent to the mask 41, allowing it to conform to the skin of the upper lip. Made of flexible material, it offers high comfort. When worn, the two sides of the flexible diaphragm 46 conform to the cheeks on both sides of the nose, forming an atomization chamber between the flexible diaphragm, the face, and the mask 41. Based on the detachable base plate 44 located in the upper space of the mask 41 divided by the flexible diaphragm 46, the second tube 30 is directly connected to the outlet end of the nebulizer 10. This utilizes the flexible material and concave structure to improve the fit and seal between the mask 40 and the face, reducing atomized gas leakage and increasing medication utilization. Furthermore, the flexible diaphragm 46 reduces facial pressure, improving comfort for children. The position of the detachable base plate 44, combined with the atomized airflow delivered by the second tube 30, prevents direct airflow into the mouth and nose, reducing the risk of choking, while allowing the atomized gas to diffuse evenly within the chamber, ensuring the medication fully acts on the respiratory tract.

[0024] The mask 41 has a silicone ring 47 on its edge and a bendable fixing piece 43 on its upper part. The flexible properties of the silicone ring 47 are used to fit the facial contours of children of different ages and fill gaps in areas such as the sides of the nose to reduce the leakage rate of atomized gas, reduce waste of medicine and ensure local drug concentration. In addition, the bendable fixing piece 43 can be used to adjust the bending angle as needed to adapt to different head circumferences and wearing postures. Combined with the fit of the flexible diaphragm 46, it enhances the wearing stability of the mask 40, while reducing facial pressure and reducing children's resistance to treatment.

[0025] The disassembly / assembly base plate 44 has a disassembly / assembly hole outlet end with a flow divider 45 connected to the disassembly / assembly base plate 44. The flow divider 45 includes an air outlet head 452, and a connecting piece 451 inclined to the air outlet direction is arranged around the side of the air outlet head 452. A spring 453 is sleeved on the outside of the air outlet head 452, and the end of the connecting piece 451 is connected to the spring 453. The inclined connecting piece 451 is used to disperse the concentrated airflow delivered by the nebulizer 10 into a diffused state, avoiding direct impact on the child's nose and airway. In addition, with the elastic buffering effect of the spring 453, it can adaptively adjust the airflow output pressure, reduce the airflow impact, and significantly reduce the risk of choking and discomfort. At the same time, the dispersed airflow can be evenly distributed in the nebulization chamber formed by the flexible diaphragm 46, increasing the contact area between the drug and the respiratory tract. Combined with the horizontal setting of the disassembly / assembly base plate 44, it further ensures stable airflow output, ultimately improving the child's treatment compliance and drug utilization efficiency.

[0026] The outer bottom of the air outlet 452 is connected to the disassembly base plate 44 via a mounting base plate 454. The disassembly base plate 44 has a groove for accommodating the mounting base plate 454, and the surface of the mounting base plate 454 is flush with the surface of the disassembly base plate 44. The surface of the mounting base plate 454 has an inner groove. The inner groove can collect the condensed atomized medication and the condensed liquid in the atomization chamber. The inner groove is designed to collect the condensed atomized medication and the condensed liquid in the atomization chamber, preventing medication loss and waste, and preventing backflow of condensate from irritating the child's respiratory tract, ensuring medication utilization and treatment safety. Furthermore, the flush design of the mounting base plate 454 with the disassembly base plate 44 eliminates protruding gaps at the connection point, reduces dead corners for dirt accumulation, and, combined with the detachable structure of the disassembly base plate 44, facilitates cleaning and disinfection, reducing the risk of bacterial growth.

[0027] The second tube 30 is connected to a regulator 50 via a one-way valve on one side. Specifically, the second tube 30 is connected to the third tube 52 of the regulator 50 via a one-way valve on one side. The inlet end of the third tube 52 is connected to an adjustment base 53. The adjustment base 53 is hollow inside and the bottom is connected to a bottle 51 via a connector 512. The adjustment base 53 has a piston 510 inside that can move up and down. This invention uses a one-way valve to block the backflow of airflow and medication, preventing contamination. Furthermore, the piston 510 is moved up and down to adjust the airflow pressure and flow rate, adapting to different children's airway resistance and treatment needs. This prevents excessively strong airflow from causing choking or excessively weak airflow from affecting medication deposition. The bottle 51 is used to store spare medication or balance air pressure. Specifically, the medication in the bottle 51 will slowly flow into the regulating channel 511 through the built-in channel of the connector 512 under the pressure change of the regulating base 53, mixing with the main airflow delivered by the nebulizer 10 to form a uniform atomized mixed airflow, extending treatment time and avoiding the need to add medication midway. While the medication is in the solution, the displacement rod 55 can be manually controlled to prevent the piston 510 from moving upwards. Additionally, when the airflow pressure increases instantaneously, the inside of the bottle 51 absorbs some of the pressure, acting as a buffer to prevent high-pressure airflow from directly impacting the child's airway.

[0028] The connector 512 has an adjustment channel 511 on one side that communicates with the third tube 52. The connector 512 is used for connection and airflow diversion. The upper part of the adjustment base 53 is open and covered with a cover plate 58. The middle of the cover plate 58 has a displacement rod 55 that can move up and down. The bottom of the displacement rod 55 is connected to the piston 510. The bottom of the cover plate 58 is connected to the piston 510 through a swing member 59. The adjustment channel 511 has a first vent pipe 54 communicating with it on one side. The swing member 59 is a rod structure with one end hinged to the bottom of the cover plate 58 and the other end hinged to the piston 510. The adjustment channel 511 and the first vent pipe 54 form an airflow passage to ensure airflow balance. The displacement rod 55 is used to limit the vertical displacement range of the piston 510 to prevent it from deviating. It also works with the hinged limiting function of the swing member 59 to prevent the piston 510 from jamming or deviating, thereby improving the accuracy and stability of airflow pressure and flow regulation.

[0029] The piston 510 moves upwards. In this upward-moving state, the internal volume of the regulating base 53 increases, the air pressure inside the cavity decreases, and the airflow rate drawn in through the regulating channel 511 increases while the pressure decreases. When the piston 510 moves downwards, the internal volume of the regulating base 53 decreases, the air pressure inside the cavity increases, and the airflow rate output to the third tube 52 decreases while the pressure increases. In this way, linear regulation of air pressure and flow rate is achieved through volume changes, adapting to the airway resistance needs of children of different ages.

[0030] A first vent pipe 54 is provided on one side of the regulating channel 511, and the first vent pipe 54 has at least two inlet and outlet holes, one of which is connected to a second vent pipe 56. An auxiliary vent hole 57 with a diameter less than 1 cm is provided on the second vent pipe 56. A guide head 513 is provided at the junction of the first vent pipe 54 and the regulating base 53, and the guide head 513 has a channel for guiding the airflow. The guide head 513 guides the airflow through its built-in channel, avoiding pressure fluctuations caused by airflow turbulence and ensuring smooth airflow delivery. Furthermore, the double-hole structure of the first vent pipe 54 forms a flow path for the main airflow and the balancing airflow, which, together with the flow-limiting effect of the small hole of the auxiliary vent hole 57, balances the internal and external air pressures of the regulating base 53, preventing excessively high air pressure from compressing the airway or excessively low air pressure from causing insufficient airflow.

[0031] A nebulizer with a child-friendly nebulizer wearing device, the nebulizer includes a nebulizer 10, and a second tube 30 connected to the outlet end of the nebulizer 10.

[0032] Example 2: In this embodiment, see Appendix Figure 1 Appendix Figure 2 As shown, the cover 41 has a side hole 42 communicating with the interior of the upper space separated by the flexible diaphragm 46. The side hole 42 is used to balance the air pressure inside and outside the nebulization chamber, to avoid the continuous input of nebulized airflow causing excessive air pressure inside the chamber to compress the child's airway, to ensure smooth breathing, and at the same time to promote the formation of airflow circulation in the nebulization chamber. With the airflow dispersion effect of the diverter 45, the nebulized gas is evenly distributed in the chamber.

[0033] Example 3: In this embodiment, see Appendix Figure 1 As shown, the atomizer 10 has a first tube 11 at its outlet end, a heater 20 is connected to the outlet end of the first tube 11, and a second tube 30 is connected to the outlet end of the heater 20. (See attached diagram) Figure 8 Appendix Figure 9 As shown, the heater 20 includes a cylindrical shell 21 with through-ends at both ends. Sealing plates are provided at both ends of the shell 21, and the sealing plates are connected to the second tube 30 and the first tube 11 respectively, so that the airflow can flow normally through the heater 20. The connection method of the second tube 30 and the first tube 11 is preferably magnetic or threaded connection, which is convenient for disassembly and assembly.

[0034] The heater 20 is used to preheat the airflow output from the atomizer 10 to prevent the low-temperature airflow from irritating the delicate airways of children.

[0035] The housing 21 has a support ring 23 arranged coaxially with it at intervals. An inner ring 26 is arranged coaxially with it inside the support ring 23. The outer side of the inner ring 26 is connected to the support ring 23 by strips 25 distributed around it at intervals. A heating element 24 is arranged around the adjacent inner rings 26. A reinforcing ring 27 is connected to the heating element 24 located on the same side of the inner ring 26. The reinforcing ring 27 is used to fix the adjacent heating element 24.

[0036] An internal support frame is formed by the coaxially arranged support ring 23, inner ring 26 and bar 25, ensuring that the heating element 24 is distributed around it, avoiding the displacement of the heating element 24 due to airflow impact, and allowing the atomized airflow to fully contact the heating element 24 to achieve uniform preheating. The further reinforcing ring 27 strengthens the connection stability of adjacent heating elements 24, improves the durability of the heating structure, and improves the permeability of atomized gas by distributing the heating element 24 around it, thus avoiding overheating.
