Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a multifunctional nebulizer that combines breathing training, expectoration, and nebulization functions. Background Technology

[0002] In clinical medicine, sputum management is a crucial part of the treatment of respiratory diseases, especially for users with thick sputum that is difficult to cough up. Effectively clearing respiratory secretions is of great significance for alleviating symptoms and preventing complications. Traditionally, these users usually rely on a combination of sputum expectorators and nebulizers for treatment. Nebulizers convert liquid medication into tiny mist particles, making it easier for users to inhale the medication, thereby relieving bronchospasm, reducing mucosal edema, thinning sputum, and promoting sputum expectoration. Sputum expectorators, on the other hand, help users expel sputum from the respiratory tract through vibration or positive expiratory pressure suction.

[0003] For example, Chinese utility model patent CN215309286U, entitled "Atomizer Assembly and Corresponding Atomizer," discloses an atomizer assembly and a corresponding atomizer. The atomizer assembly includes a ceramic plate and a metal plate. The ceramic plate is annular with a central hole and a connecting groove on one side. The metal plate is circular and connected to the connecting groove. An atomization area is provided in the center of the atomization area, and multiple atomization holes are provided in the atomizer area. The atomizer includes an atomizer body, a medicine box, and a nozzle. A power source is provided inside the atomizer body. The medicine box is connected to one end of the atomizer body and has a connecting protrusion on the outside. The connecting protrusion has an installation groove in the center and a first snap-fit ​​groove on the outside. The atomizer assembly is connected to the installation groove and electrically connected to the power source. The nozzle is hollow and cylindrical, fitted onto the connecting protrusion. A first snap-fit ​​protrusion is provided corresponding to the position of the first snap-fit ​​groove, and the first snap-fit ​​protrusion connects to the first snap-fit ​​groove. The nebulizer of this invention has a nozzle that is snapped together with the medicine box, which facilitates maintenance and replacement of the nebulizer components and extends the service life of the nebulizer.

[0004] Existing nebulizers typically only have basic drug nebulization functions. When inhaling gas through a nebulizer, the gas travels straight up and down through the airway, and the drug particles are delivered directly to the user's mouth through the tubing after nebulization. After using the nebulizer for treatment, the user needs to use a sputum expectorator to clear sputum, requiring a step-by-step treatment, which increases the complexity of the user's operation. Furthermore, when the nebulized drug is delivered directly to the user's mouth through the tubing, the drug is exhaled before it has fully reached the effective site, resulting in a short drug residence time and insignificant effects. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a multifunctional nebulizer that combines breathing training, expectoration, and nebulization functions. The inhalation vibration nebulization method allows the medication to reach the lesion site more deeply, effectively, and quickly, resulting in greater drug deposition in the airways and lungs, a longer drug residence time, and a more significant nebulization effect.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a multifunctional nebulizer that combines breathing training, sputum expectoration, and nebulization functions, characterized in that it includes a nebulizer connecting housing, on which an air vent and a nebulization interface are provided, the mouthpiece for the user to exhale and inhale is connected to the air vent, the nebulizer assembly is connected to the nebulization interface, the working end of the nebulizer connecting housing is provided with a gas flow structure that connects the working chamber to the outside, and an oscillation structure that can generate vibration during use is provided near the gas flow structure.

[0007] In the above technical solution, the atomizer assembly includes an atomizing connector and an atomizing cup. The atomizing connector has a hollow cavity inside. The air outlet of the atomizing connector is connected to the atomizing interface of the atomizer connecting housing. A pressure relief part is provided at the other end of the cavity opposite to the air outlet. An opening is provided on the cavity wall of the atomizing connector between the air outlet and the pressure relief part. One end of the air inlet is connected to the opening, and the other end of the air inlet is connected to the atomizing cup. This makes it more convenient to use and the layout is more scientific and reasonable.

[0008] In the above technical solution, a one-way airflow control component is provided at the connection transition between the atomizing interface and the air outlet, including a one-way airflow control seat fixedly installed at the atomizing interface and a valve plate installed on the one-way airflow control seat to control the unidirectional flow of gas, which helps to avoid excessive pressure in the atomizing pipeline.

[0009] In the above technical solution, the working end of the nebulizer connecting shell includes an exhalation working end and an inhalation working end disposed at both ends of the nebulizer connecting shell, and the oscillation structure includes a positive pressure oscillation component disposed near the exhalation working end and a negative pressure oscillation component disposed near the inhalation working end.

[0010] In the above technical solution, the positive pressure oscillation component includes a positive pressure oscillation base and a positive pressure oscillation bead disposed in the cavity of the positive pressure oscillation base. Under positive pressure, the positive pressure oscillation bead moves in the cavity and then oscillates the air. The oscillating air can resonate with the user's lungs, effectively loosening the phlegm that has fallen off the tracheal wall.

[0011] In the above technical solution, the bottom of the positive pressure oscillation base is provided with an exhalation hole that matches the arc surface of the positive pressure oscillation bead. In the initial state, the exhalation channel is closed by the arc surface of the oscillation bead.

[0012] In the above technical solution, the negative pressure oscillation component includes a negative pressure oscillation upper seat, a negative pressure oscillation lower seat, and negative pressure oscillation beads disposed in an oscillation cavity formed by the negative pressure oscillation upper seat and the negative pressure oscillation lower seat. The negative pressure oscillation beads move within the cavity and oscillate the air, which allows the medicine to reach the lesion site more deeply, effectively, and quickly, improves the effectiveness of nebulization, enhances the nebulization therapeutic effect, and trains the inspiratory muscles and lung function.

[0013] In the above technical solution, the top of the cavity of the upper negative pressure oscillator and the bottom of the cavity of the lower negative pressure oscillator are respectively provided with air intake holes that match the arc surface of the negative pressure oscillating bead. In the initial state, the air intake channel is closed by the arc surface of the oscillating bead.

[0014] In the above technical solution, the gas flow structure includes an expiratory regulating component disposed on the expiratory working end and an inspiratory regulating component disposed on the inspiratory working end.

[0015] In the above technical solution, the expiratory adjustment component includes an expiratory connector for connecting to the expiratory working end of the nebulizer connecting housing and an expiratory adjustment cover disposed on the expiratory connector for adjusting the ventilation volume. The structure of the inspiratory adjustment component is the same as that of the expiratory adjustment component, including an inspiratory connector for connecting to the nebulizer connecting housing of the inspiratory working end and an inspiratory adjustment cover disposed on the inspiratory connector for adjusting the ventilation volume. The blowing resistance can be adjusted according to the individual differences of the user to meet personalized treatment needs.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present application provides an air vent and a nebulization interface connected to the working chamber on the nebulizer connecting housing. An oscillating structure that generates vibration during use is provided within the working chamber. Vibration waves are generated during exhalation and inhalation during nebulization. This vibration dislodges sputum while allowing the medication to reach the lesion site more deeply, effectively, and quickly, improving the effectiveness of nebulization. It enhances the therapeutic effect of nebulization while training the inspiratory muscles and lung function, achieving the optimal drug-efficacy ratio with the minimum nebulization dosage. This allows users to simultaneously perform nebulization therapy, breathing training, and sputum loosening during treatment, simplifying the treatment process and eliminating the need for step-by-step treatment, thus improving the convenience of treatment. The nebulizer in this solution has a nozzle that snaps into the medicine box, facilitating maintenance and replacement of the nebulizer components, and extending the nebulizer's service life.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] The following description is intended to disclose the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0027] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this invention.

[0028] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0029] See Figures 1 to 7A multifunctional nebulizer that combines breathing training, expectoration and nebulization functions includes a nebulizer connecting housing 1. Preferably, the nebulizer connecting housing 1 is a cylindrical structure. Of course, it is not limited to this structure. The cylindrical structure is mainly convenient to carry and the processing technology is simpler, which helps to reduce manufacturing costs and improve market competitiveness. Therefore, the shape of the nebulizer connecting housing 1 can be adapted to actual use needs.

[0030] An air vent 11 and an atomization interface 12 are provided on the side wall of the atomizer connecting housing 1. In this design, the air vent 11 and the atomization interface 12 are symmetrically arranged on the two side walls of the atomizer connecting housing 1. Both the air vent 11 and the atomization interface 12 can connect the working chamber 10 to the outside. The upper and lower working ends of the atomizer connecting housing 1 are open, serving as the exhalation working end 13 and the inhalation working end 14, respectively. Thus, the four open structures of the air vent 11, the atomization interface 12, the exhalation working end 13, and the inhalation working end 14 form a cross-shaped structure. Of course, this is the setting of this design, and it can be adapted to actual usage requirements.

[0031] A mouthpiece 2 for the user to exhale and inhale is connected to the air vent 11. Of course, the mouthpiece 2 also has a channel communicating with the air vent 11, allowing the user to exhale gas into the working chamber 10 or inhale gas from the working chamber 10.

[0032] The nebulizer assembly is connected to the nebulization interface 12, including the nebulization connector 3 for connecting to the nebulization interface 12 and the nebulization cup for containing the medicine. The structure of the nebulization cup is omitted in the attached drawings of this embodiment, that is to say, the structure of the nebulization cup can be arbitrary, as long as it can be connected to the nebulization connector 3.

[0033] The working end of the atomizer connecting housing 1 is provided with a gas flow structure that connects the working chamber 10 with the outside. Near the gas flow structure, there is an oscillation structure that can generate vibration during use.

[0034] The atomizing connector 3 has a hollow cavity inside. The atomizing connector 3 is provided with an air outlet, a pressure relief section 31 and an air inlet section 32. The air outlet and the pressure relief section 31 are located at opposite ends of the hollow cavity. An opening is provided on the cavity wall of the atomizing connector between the air outlet and the pressure relief section 31. One end of the air inlet section 32 is connected to the opening, and the other end of the air inlet section 32 is connected to the atomizing cup.

[0035] The pressure relief section 31 has several through holes on its end wall, which can prevent treatment failure caused by excessive pressure in the air intake section 32 leading to detachment from the atomizing connector 3. The pressure relief section 31 can automatically relieve pressure in the air intake section 32, thereby ensuring the stability of the connection.

[0036] Of course, a one-way airflow control component 33 is provided at the connection transition between the atomizing interface 12 and the air outlet, including a one-way airflow control seat 331 fixedly installed at the atomizing interface 12 and a valve plate 332 installed on the one-way airflow control seat 331 to control the unidirectional flow of gas. In this way, the valve plate 332 will only open when there is negative pressure in the inhalation, and the atomized medicine will enter the working chamber 10 from the air inlet 32 ​​through the air outlet and then enter the user through the mouthpiece 2.

[0037] Of course, to ensure that vibration waves are generated during both exhalation and inhalation during the nebulization process, the working end of the nebulizer connecting housing 1 includes an exhalation working end 13 and an inhalation working end 14. A positive pressure oscillation component 4 is provided near the exhalation working end 13, and a negative pressure oscillation component 5 is provided near the inhalation working end 14.

[0038] The positive pressure oscillation component 4 is mainly used to oscillate the air when the user exhales. The oscillating airflow can resonate with the user's lungs, thereby loosening the phlegm that has fallen off the tracheal wall. The user can then expel the phlegm from the respiratory tract by coughing or other means.

[0039] The positive pressure oscillation assembly 4 includes a positive pressure oscillation base 41 and a positive pressure oscillation bead 42 disposed in the cavity of the positive pressure oscillation base 4.

[0040] The positive pressure oscillation base 41 has a conical funnel-shaped structure with two openings, one large and one small. The top opening is larger and the bottom opening is smaller, which matches the exhalation hole of the positive pressure oscillation bead 42. The diameter of the exhalation hole opening is smaller than the diameter of the oscillation bead 42 to prevent the oscillation bead 42 from falling out of the exhalation hole. This cavity forms an oscillation chamber. The positive pressure oscillation bead 42 is placed in the oscillation chamber. Under normal conditions, the bottom surface of the positive pressure oscillation bead 42 always remains engaged with the bottom exhalation hole, blocking the connection between the exhalation working end 13 and the working chamber 10.

[0041] Correspondingly, the negative pressure oscillation component 5 is mainly used to oscillate the air when the user inhales. The vibration waves drive the gas, causing it to change its path. It may enter the airway in a wave-like or spiral shape, increasing the contact area between the atomized gas and the airway wall, making it easier to adhere to the airway wall and alveoli. This allows more drugs to be deposited in the airway and lungs, resulting in a longer drug residence time and a more significant effect. At the same time, it trains the inspiratory muscles, achieving a breathing training effect.

[0042] The negative pressure oscillation assembly 5 includes a negative pressure oscillation upper seat 51, a negative pressure oscillation lower seat 52, and a negative pressure oscillation bead 53. Similarly, the structure of the negative pressure oscillation upper seat 51 and the negative pressure oscillation lower seat 52 is the same as that of the positive pressure oscillation base 41, both being conical funnel-shaped structures. The conical funnel-shaped structure has two opening ends, one large and one small. The large opening end of the negative pressure oscillation upper seat 51 fits into the large opening end of the negative pressure oscillation lower seat 52. The negative pressure oscillation bead 53 is set in the negative pressure oscillation cavity formed by the cooperation of the negative pressure oscillation upper seat 51 and the negative pressure oscillation lower seat 52. Of course, when the sputum suction device is always placed in a vertical position, the negative pressure oscillation upper seat 51 can be omitted. However, in use, people usually store it horizontally. In order to prevent the negative pressure oscillation bead 53 from rolling out of the negative pressure oscillation cavity, the negative pressure oscillation upper seat 51 is provided. The small opening at the top of the cavity of the negative pressure oscillation upper seat 51 is used for the airflow of inhalation. It is worth mentioning that, under normal conditions, the negative pressure oscillating bead 53 always keeps its bottom surface fitted with the small opening, i.e., the suction hole, of the negative pressure oscillating lower seat 52, thus blocking the connection between the suction working end 14 and the working chamber 10.

[0043] In order to adjust the blowing or inhalation resistance according to individual user differences, meet personalized treatment needs, and improve the effectiveness of sputum expectoration and breathing training, an expiratory adjustment component 6 is provided on the expiratory working end 13, and an inhalation adjustment component 7 is provided on the inhalation working end 14.

[0044] The exhalation adjustment assembly 6 includes an exhalation connector 61 and an exhalation adjustment cover 62. The exhalation connector 61 is provided with a connecting structure for connecting to the housing of the exhalation working end 13. The exhalation adjustment cover 62 is movably disposed on the upper working end of the exhalation connector 61 and can rotate coaxially with respect to the upper working end of the exhalation connector 61. Of course, both the exhalation connector 61 and the exhalation adjustment cover 62 are provided with an exhalation hole 611 and an exhalation adjustment hole 621. In order to facilitate users to adjust the exhalation resistance more intuitively, an exhalation resistance indicator 612 is provided on the exhalation connector 61.

[0045] The structure of the inhalation adjustment assembly 7 is the same as that of the exhalation adjustment assembly 6, and also includes an inhalation connection seat 71 and an inhalation adjustment cover 72. The inhalation connection seat 71 is also provided with a connection structure that connects to the housing of the inhalation working end 14. The inhalation adjustment cover 72 is rotatably mounted on the inhalation connection seat 71. The inhalation resistance is adjusted by adjusting the opening of the inhalation hole and the inhalation adjustment hole. It is simpler and more convenient than the traditional structure. Of course, the inhalation resistance mark 711 is also provided on the inhalation connection seat 71.

[0046] When using this invention, the user holds the nebulizer with the exhalation working end facing upwards and the inhalation working end facing downwards, and installs the nebulizer cup on the air inlet of the nebulizer connector. At this time, the positive pressure oscillating bead keeps its bottom surface fitted with the bottom exhalation hole, blocking the connection between the exhalation working end and the working chamber, and the negative pressure oscillating bead keeps its bottom surface fitted with the small opening of the negative pressure oscillating lower seat, i.e., the inhalation hole, blocking the connection between the inhalation working end and the working chamber.

[0047] The user holds the mouthpiece in their mouth and inhales through the mouthpiece channel. Under negative pressure, the valve opens, allowing the nebulized medication to enter the working chamber from the air inlet and then through the mouthpiece into the user's airway. Simultaneously, the negative pressure oscillating bead detaches from the inhalation port, connecting the inhalation working end to the working chamber. After inhalation, the negative pressure oscillating bead falls downwards under its own weight, generating vibration through this continuous rising and falling motion. During exhalation, the valve closes under positive pressure, preventing the nebulized medication from returning to the nebulizer cup. Simultaneously, the positive pressure oscillating bead generates an upward thrust, rising and detaching from the exhalation port, connecting the exhalation working end to the working chamber. After exhalation, the positive pressure oscillating bead falls downwards under its own weight. This process of inhalation and exhalation... During the alternating positive and negative pressure oscillating beads, both rise and fall, creating vibrations. In this process, the oscillating airflow of positive pressure exhalation resonates with the user's lungs, loosening phlegm from the tracheal walls, allowing the user to expel it through coughing. The vibrations generated during negative pressure inhalation help dislodge phlegm from the airways while simultaneously training the inspiratory muscles. The inhalation of vibratory nebulizers causes the gas to change its path, potentially entering the airways in a wave-like or spiral shape. This increases the contact area between the nebulized gas and the airway walls, making it easier for the gas to adhere to the airway walls and alveoli, resulting in greater drug deposition in the airways and lungs, longer drug retention time, and more significant effects.

[0048] When users need to adjust the blowing or inhalation resistance according to individual differences, they only need to refer to the blowing resistance and inhalation resistance markings, rotate the exhalation adjustment cap or the inhalation adjustment cap, and adjust the opening between the exhalation through-hole and the exhalation adjustment hole or the inhalation through-hole and the inhalation adjustment hole to adjust the inhalation resistance.

[0049] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
