Description

Technical Field

[0001] This application relates to the field of medical devices, and more particularly to a nebulizer assembly and a nebulizer. Background Technology

[0002] In the field of medical devices, nebulizers are common medical devices used to convert liquid medications into aerosol form for patients to inhale. Typically, a nebulizer consists of: a main body with a compressor for generating compressed air; and a nebulizer assembly, which includes components such as a medication cup. The nebulizer assembly is used to convert the liquid medication in the medication cup into an aerosol by introducing compressed air.

[0003] Nebulizers are simple and convenient to operate, but patients are required to maintain a sitting or leaning posture during nebulization therapy. Existing medicine cups are generally placed vertically and usually only support a maximum tilt of 45°.

[0004] It should be noted that the above description of the background technology is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background technology section of this application. Utility Model Content

[0005] The inventors discovered that in the existing nebulizers, if the patient is a young child, an elderly person, or a critically ill patient who is unable to sit up, it is difficult to maintain a stable sitting posture during a long nebulization treatment. In this case, the medicine cup may need to be tilted at a large angle or even horizontally. This will cause the suction tube in the medicine cup to not contact the medicine, making it impossible to continue spraying, and the medicine will flow out from the mist outlet or air inlet, resulting in waste.

[0006] To address one of the aforementioned problems or other similar issues, embodiments of this application provide an atomizer assembly and an atomizer that enable the atomizer assembly to draw in liquid medication even when in a horizontal position, and prevent the liquid medication from easily flowing out of the cup.

[0007] According to a first aspect of the present application, an atomizer assembly is provided, wherein the atomizer assembly includes: a cup body, the cup body being provided with a nozzle integrally formed with the bottom, the nozzle extending through the bottom in a vertical direction; a suction tube, the suction tube being received inside the cup body and covering the nozzle on the outer surface of the nozzle located inside the cup body with a gap; and a flow path forming body, the flow path forming body being detachably engaged with the cup body, the flow path forming body being provided with an external air inlet tube, the external air inlet tube being disposed on the bottom surface of the flow path forming body and extending downward from the bottom surface of the flow path forming body inside the cup body. When viewed axially, a first sidewall of the wall portion of the cup body is formed as a non-linear structure that clamps the external air inlet tube, and the suction tube is closer to the first sidewall of the wall portion than a second sidewall of the wall portion that is radially opposite to the first sidewall.

[0008] In some embodiments, at least a portion of the suction tube and the nozzle are housed in the external air inlet tube, and a portion of the inner surface of the first sidewall of the cup body is tightly fitted with a portion of the outer surface of the external air inlet tube.

[0009] In some embodiments, the external air inlet pipe is provided with a first baffle that extends radially inward from the inner surface of the first sidewall of the external air inlet pipe near the wall portion.

[0010] In some embodiments, the radial height of the first baffle is not greater than the radial distance from the center of the nozzle to the first sidewall of the cup body.

[0011] In some embodiments, when viewed axially, the non-linear structure of the first sidewall of the cup body includes two first arms and a first connecting arc connecting the two first arms. The distance between the two first arms gradually increases from the first connecting arc along the direction from the first sidewall of the cup body to the second sidewall of the cup body. A portion of the inner surface of the first sidewall of the cup body is tightly fitted with a portion of the outer surface of the external air inlet pipe at the first connecting arc.

[0012] In some embodiments, viewed axially, the non-linear structure of the first sidewall of the cup body includes two parallel second arms and a second connecting arc portion connecting the two second arms, and a portion of the inner surface of the first sidewall of the cup body is tightly fitted with a portion of the outer surface of the external air inlet pipe at least a portion of the second connecting arc portion.

[0013] In some embodiments, the external air inlet pipe is further provided with a second baffle, the second baffle extending radially outward from the outer surface of the external air inlet pipe that is not tightly fitted with the wall of the cup body, and at least a portion of the second baffle being tightly fitted with the inner surface of the first sidewall of the wall of the cup body.

[0014] In some embodiments, the first baffle is provided with a partition, which extends downward from the lower surface of the first baffle at a position opposite to the upper nozzle orifice of the nozzle, and extends to a point where there is a first gap between the partition and the upper nozzle orifice of the nozzle.

[0015] In some embodiments, when viewed axially, the first sidewall of the wall portion is connected to the second sidewall of the wall portion by an arc.

[0016] According to a second aspect of the embodiments of this application, an atomizer is provided, the atomizer including the atomizer assembly described in the first aspect above.

[0017] One of the beneficial effects of this application embodiment is that, according to this application embodiment, the first sidewall of the suction tube is formed as a non-linear structure closer to the second sidewall of the wall portion than the wall portion, and the first sidewall of the wall portion is formed as a non-linear structure that clamps the external air inlet tube. That is, the first sidewall of the wall portion is formed as a non-linear structure that bends toward the external air inlet tube. Thus, even when the atomizer assembly is in a horizontal position, the liquid can be drawn through the suction tube. At the same time, a portion of the inner surface of the first sidewall of the cup portion is tightly fitted with a portion of the outer surface of the external air inlet tube, so that the liquid will not flow out of the cup portion even when the atomizer assembly is in a horizontal position.

[0035] First aspect of the embodiments

[0036] An embodiment of the first aspect of this application provides an atomizer assembly.

[0037] Figure 1 This is a schematic diagram of an atomizer assembly according to an embodiment of the first aspect of this application, showing a perspective view of the atomizer assembly; Figure 2 This is another schematic diagram of an atomizer assembly according to an embodiment of the first aspect of this application. The left side shows a front view of the atomizer assembly, and the right side shows a side view of the atomizer assembly. Figure 3 It is along Figure 2 A cross-sectional view of the atomizer assembly shown by line L1-L1'; Figure 4 It is along Figure 2 Another cross-sectional view of the atomizer assembly shown by line L2-L2'; Figure 5 This is a schematic diagram of the cup body according to an embodiment of the first aspect of this application; Figure 6 This is a schematic diagram of a flow path forming body according to an embodiment of the first aspect of this application, showing a bottom view of the flow path forming body viewed from below.

[0038] like Figures 1 to 5As shown, the atomizer assembly 1 may include: a cup body 10, a suction tube 20, and a flow path forming body 30. The cup body 10 is provided with a nozzle 103 integrally formed with the bottom 101 of the cup body 10, extending vertically through the bottom 101. The suction tube 20 is housed inside the cup body 10, and covers the outer surface F1 of the nozzle 103 located inside the cup body 10 with a gap. The flow path forming body 30 is detachably engaged with the cup body 10, and is provided with an external air inlet tube 302, which is located on the bottom surface FD of the flow path forming body 30 and extends downwards from the bottom surface FD inside the cup body 10.

[0039] like Figure 3 and Figure 4 As shown, the wall portion 104 of the cup body 10 is composed of a first sidewall 1041 and a second sidewall 1042 that is radially opposite to the first sidewall 1041; viewed axially, the first sidewall 1041 of the wall portion 104 is formed as a non-linear structure that clamps the external air inlet tube 302, that is, the first sidewall 1041 of the wall portion 104 has a structure that bends toward the external air inlet tube 302; and the suction tube 20 is closer to the first sidewall 1041 of the wall portion 104 than the second sidewall 1042 of the wall portion 104.

[0040] According to the above embodiment, the suction tube 20 is closer to the first side wall 1041 of the wall 104, which is a non-linear structure, relative to the second side wall 1042 of the wall 104. Furthermore, the first side wall 1041 of the wall 104 is formed in a non-linear structure that clamps the external air inlet tube 302. In other words, the first side wall 1041 of the wall 104 is formed in a non-linear structure that bends toward the external air inlet tube 302. As a result, even when the atomizer assembly 1 is in a horizontal position, the liquid can be drawn through the suction tube 20. At the same time, since a portion of the inner surface of the first side wall 1041 of the wall 10 of the cup body 10 is tightly fitted with a portion of the outer surface of the external air inlet tube 302, the liquid will not flow out of the cup body 10 even when the atomizer assembly 1 is in a horizontal position, thus preventing waste of the liquid. Furthermore, by placing the suction tube 20 closer to the first sidewall 1041 of the wall 104 relative to the second sidewall 1042 of the wall 104, it is easier to filter out large particles generated by atomization, which helps to reduce the particle size and thus makes it easier for patients to absorb the atomized gas.

[0041] In this embodiment of the application, for example, the cup body 10 has a bottom 101 at the lower end and an opening 102 at the upper end, such as... Figure 3 As shown, the flow path forming body 30 can be detachably engaged with the opening 102 of the cup body 10.

[0042] In the embodiments of this application, such as Figures 1 to 4As shown, the flow path forming body 30 may also be provided with a mist outlet 301. The mist outlet 301 is formed on the upper surface of the flow path forming body 30 in such a way that it penetrates a part of the upper surface FU of the flow path forming body 30. A gas flow path (such as) can be formed between the external gas inlet pipe 302 and the mist outlet 301. Figure 3 (The direction indicated by arrow A). In the embodiments of this application, as... Figure 4 As shown, the first sidewall 1041 of the wall portion 104 is formed with a different shape and structure from the second sidewall 1042, and the first sidewall 1041 is not a straight structure. Thus, for example, when the nebulizer assembly 1 is inverted (placed horizontally) with the patient lying down, the non-straight structure of the first sidewall 1041 causes the liquid to converge, thereby raising the liquid level. Furthermore, because the suction tube 20 and the first sidewall 1041 are close together, the liquid level is easily reached at the height S1 (e.g., the distance between the suction port 201 of the suction tube 20 and the first sidewall 1041) when the tube is horizontal. Figure 3 (As shown), thus, even when the atomizer assembly 1 is in a horizontal position, the liquid medication can be drawn through the suction tube 20. In the embodiments of this application, the structure of the first sidewall 1041 of the wall portion 104 is not limited to... Figure 4 The V-shaped structure shown, including any non-linear structure that bends towards the second sidewall 1042 in a manner that clamps the external air inlet pipe 302, is included in this application. That is, the structure of the first sidewall 1041 of the wall portion 104 extends from the point P (where it is tightly fitted with the external air inlet pipe 302)... Figure 4 As shown, the first sidewall 1041 extends to the second sidewall 1042 of the wall portion 104 in a manner that clamps the external air inlet tube 302. Such a construction of the first sidewall 1041 allows the liquid to accumulate at the bottom of the first sidewall 1041 when the atomizer assembly 1 is in a horizontal position.

[0043] In the embodiments of this application, such as Figure 3 and Figure 4 As shown, at least a portion of the suction tube 20 and the nozzle 103 are housed in the external air inlet tube 302; a portion of the inner surface of the first side wall 1041 of the wall portion 104 of the cup body 10 is tightly fitted with a portion of the outer surface of the external air inlet tube 302.

[0044] In the embodiments of this application, such as Figure 3 As shown, the outer surface of the external air inlet pipe 302, at the portion inserted into the cup body 10, and the inner surface of the first side wall 1041 of the cup body 10 wall 104, which is radially opposite to this portion, are both axially fitted together (e.g., Figure 3As shown by the dashed line DL), that is, the two are tightly fitted together by an interference fit. However, it is not necessary for the outer surface of the external air inlet pipe 302 and the inner surface of the first side wall 1041 to be tightly fitted together for the entire dashed line DL. For example, it can be only a certain section in the axial direction (for example, the two are tightly fitted together in a certain section of the dashed line DL instead of being tightly fitted together for the entire dashed line DL). In this way, the liquid will not flow out of the cup body 10 when the atomizer assembly 1 is in a horizontal position.

[0045] In the embodiments of this application, such as Figure 3 and Figure 6 As shown, the external air inlet pipe 302 is provided with a first baffle 3021, which extends radially inward from the inner surface F2 of the first side wall 1041 near the wall portion 104 of the external air inlet pipe 302. Thus, because the first baffle 3021 is provided on the inner surface F2 of the external air inlet pipe 302, it is possible to further prevent the liquid medicine from flowing out from the air inlet 303 of the flow path forming body 30.

[0046] In this embodiment, the maximum liquid level height when the atomizer assembly 1 is in a horizontal position generally does not exceed the radial distance from the center of the nozzle 103 to the first sidewall 1041 of the wall 104 of the cup body 10. To better prevent the liquid from flowing out of the air inlet 303 of the flow path forming body 30, such as... Figure 4 As shown, the radial height H1 of the first baffle 3021 can be set to be no greater than the radial distance from the center of the nozzle 103 to the first sidewall 1041 of the wall 104 of the cup body 10. Under normal circumstances, such as... Figure 3 As shown, the suction tube 20, the nozzle 103 and the external air inlet tube 302 can be coaxially arranged. In this case, when viewed along the axial direction, the center of the first baffle 3021 is basically aligned with the center of the nozzle 103.

[0047] In the embodiments of this application, such as Figure 3 , Figure 4 and Figure 6 As shown, the external air inlet pipe 302 is also provided with a second baffle 3022. The second baffle 3022 extends radially outward from the outer surface of the external air inlet pipe 302 that is not tightly fitted with the wall portion 104 of the cup body 10, and at least a portion of the second baffle 3022 is tightly fitted with the inner surface of the first side wall 1041 of the wall portion 104 of the cup body 10. That is, the structure of the second baffle 3022 opposite to the first side wall 1041 is adapted to the structural shape of the first side wall 1041 so as to achieve a tight fit through the interference fit between the two. In this way, by providing the second baffle, the liquid medicine can be prevented from flowing out of the mist outlet 301 when the atomizer assembly 1 is in a horizontal position.

[0048] The following describes a specific embodiment of the structure of the first sidewall 1041 of the wall portion 104 of the cup body 10.

[0049] Implementation Method 1

[0050] When viewed along the axial direction, the non-linear structure of the first side wall 1041 of the wall portion 104 of the cup body 10 that clamps the external air inlet pipe 302 can be an arc-shaped structure (not shown) with a curvature different from that of the second side wall 1042 of the wall portion 104. For example, the curvature of the first side wall 1041 is greater than that of the second side wall 1042, that is, the degree of curvature of the first side wall 1041 is greater than that of the second side wall 1042.

[0051] In this embodiment, when viewed along the axial direction, the arc-shaped structure of the first sidewall 1041 can be composed of arcs with the same curvature or spliced ​​together from arcs with different curvatures.

[0052] This ensures that the liquid medication is concentrated on the first side wall 1041 when the atomizer assembly 1 is in a horizontal position, making it easier for the suction tube 20 to draw up the liquid medication to the maximum extent and avoiding waste.

[0053] Implementation Method 2

[0054] like Figure 4 As shown, viewed along the axial direction, the non-linear structure of the first sidewall 1041 of the wall portion 104 of the cup body 10 may include two first arms 10411 and a first connecting arc portion 10412 connecting the two first arms 10411. The distance between the two first arms 10411 gradually increases from the first connecting arc portion 10412 along the direction from the first sidewall 1041 to the second sidewall 1042. A portion of the inner surface of the first sidewall 1041 of the wall portion 104 of the cup body 10 is tightly fitted with a portion of the outer surface of the external air inlet pipe 302 at the first connecting arc portion 10412.

[0055] In other words, the non-linear structure of the first sidewall 1041 in this embodiment can be roughly formed into a V-shaped structure.

[0056] In this embodiment, when viewed axially, the two first arms 10411 of the first sidewall 1041 can be as follows: Figure 4 The arm shown is formed by a single straight line segment, but is not limited to this. For example, the first arm 10411 can also be formed by splicing two or more straight line segments.

[0057] Similarly, the first connecting arc 10412 can also be as follows: Figure 4 The connecting arc shown is composed of arcs with the same curvature, but is not limited to this. For example, the first connecting arc 10412 can also be a connecting arc spliced ​​together from arcs with different curvatures.

[0058] This ensures that when the nebulizer assembly 1 is in a horizontal position, the liquid medication is concentrated on the first side wall 1041, making it easier for the suction tube 20 to draw in the medication to the maximum extent and avoiding waste; at the same time, Figure 4 As shown by arrow B, the first sidewall 1041 of the V-shaped structure is conducive to guiding the atomized particles of the liquid medicine to be discharged to the mist outlet 301 with high efficiency.

[0059] Implementation Method 3

[0060] Figure 7 This is a schematic diagram of a modified example of the atomizer assembly according to the first aspect of this application, showing a perspective view of the modified example of the atomizer assembly; this modified example is... Figures 1 to 6 The main difference between the atomizer components in the two lies in the structure of the cup; Figure 8 This is a front view of a modified example of an atomizer assembly according to an embodiment of the first aspect of this application; Figure 9 It is along Figure 8 A cross-sectional view of a deformed example of an atomizer assembly, shown by line L3-L3'.

[0061] like Figures 7 to 9 As shown, viewed along the axial direction, the non-linear structure of the first sidewall 1041 of the wall portion 104 of the cup body 10 may include two parallel second arms 10413 and a second connecting arc portion 10414 connecting the two second arms. A portion of the inner surface of the first sidewall 1041 of the wall portion 104 of the cup body 10 is tightly fitted with at least a portion of the second connecting arc portion 10414 and a portion of the outer surface of the external air inlet pipe 302.

[0062] In other words, the non-linear structure of the first sidewall 1041 in this embodiment can be roughly formed into a U-shaped structure.

[0063] In this embodiment, when viewed axially, the two second arms 10413 of the first sidewall 1041 can be as follows: Figure 9 The arm shown is formed by a single straight line segment, but is not limited to this. For example, the second arm 10413 can also be formed by splicing two or more straight line segments. The second arm 10413 on the left and the second arm 10413 on the right, which are formed by splicing multiple straight line segments, are generally parallel.

[0064] Similarly, the second connecting arc 10414 can also be as follows: Figure 9 The connecting arc shown is composed of arcs with the same curvature, but is not limited to this. For example, the second connecting arc 10414 can also be a connecting arc spliced ​​together from arcs with different curvatures.

[0065] This ensures that the liquid medication is concentrated on the first side wall 1041 when the atomizer assembly 1 is in a horizontal position, making it easier for the suction tube 20 to draw up the liquid medication to the maximum extent and avoiding waste.

[0066] Compared to the non-linear structure of the first sidewall 1041 in Embodiment 3, the non-linear structure of the first sidewall 1041 in Embodiment 2 can accommodate a larger amount of liquid medicine.

[0067] Compared to Embodiments 1 and 2, in Embodiment 3, the area where the non-linear structure of the first sidewall 1041 is tightly fitted with the external air inlet pipe 302 is larger. Therefore, in Embodiment 3, the tight fit between the external air inlet pipe 302 and the first sidewall 1041 is sufficient to prevent the liquid medicine from flowing out. Thus, in Embodiment 3, the second baffle 3022 is unnecessary, thereby simplifying the components compared to Embodiments 1 and 2.

[0068] In the embodiments of this application, such as Figure 3 As shown, the first baffle 3021 is provided with a partition 30211. The partition 30211 extends downward from the lower surface of the first baffle 3021, where it is vertically opposite to the upper nozzle opening 1031 of the nozzle 103, until a first gap G1 exists between it and the upper nozzle opening 1031 of the nozzle 103. Atomized aerosol is formed by the impact of the liquid sprayed from the upper nozzle opening 1031 with the partition 30211. In this way, by integrally forming the partition 30211 on the first baffle 3021, the assembly process of the atomizer assembly 1 can be simplified.

[0069] In the embodiments of this application, such as Figure 1 As shown, the atomizer assembly 1 may also include a cover 40, which is detachably engaged with the upper side of the flow path forming body 30, and the atomizer assembly 1 enters the external air through the gap between the cover 40 and the flow path forming body 30.

[0070] Figure 10 It is along Figure 2 The cross-sectional view of the atomizer assembly is shown by line L4-L4'.

[0071] like Figure 10 As shown, the suction tube 20 may have a wing 202 and a claw 203. The wing 202 extends radially outward from the outer surface of the suction tube 20, and its upper surface abuts against the lower surface of the external air inlet tube 302. The claw 203 extends downward from the lower surface of the main body of the suction tube 20, and its claw abuts against the bottom 101 of the cup body 10. In this way, the suction tube 20 can be firmly positioned inside the cup body 10.

[0072] In the embodiments of this application, such as Figure 4 and Figure 9 As shown, when viewed along the axial direction, the first sidewall 1041 and the second sidewall 1042 of the wall portion 104 are connected by an arc. That is to say, the connection between the first sidewall 1041 and the second sidewall 1042 is a smooth transition. This is beneficial for guiding the atomized particles of the liquid medicine to be discharged to the mist outlet with high efficiency.

[0073] The above description only describes the configuration of the atomizer assembly related to the embodiments of this application. This application is not limited to this. The atomizer assembly may also include other conventional configurations. For details, please refer to the relevant technology. The description is omitted here.

[0074] According to the nebulizer assembly of this application embodiment, the suction tube 20 is closer to the first side wall 1041 of the wall 104, which is a non-linear structure, relative to the second side wall 1042 of the wall 104. The first side wall 1041 of the wall 104 is formed to clamp the external air inlet tube 302 in a non-linear structure. That is, the first side wall 1041 of the wall 104 is formed to bend towards the external air inlet tube 302 in a non-linear structure. Therefore, even when the nebulizer assembly 1 is in a horizontal position, the liquid can be drawn through the suction tube 20. At the same time, a part of the inner surface of the first side wall 1041 of the wall 10 of the cup body 10 is tightly fitted with a part of the outer surface of the external air inlet tube 302. In this way, even when the nebulizer assembly 1 is in a horizontal position, the liquid will not flow out of the cup body 10, thereby avoiding waste of the liquid. Furthermore, by placing the suction tube 20 closer to the first sidewall 1041 of the wall 104 relative to the second sidewall 1042 of the wall 104, it is easier to filter out large particles generated by atomization, which helps to reduce the particle size and thus makes it easier for patients to absorb the atomized gas.

[0075] Second aspect of the embodiments

[0076] The second aspect of this application provides an atomizer, which includes the atomizer assembly 1 described in the first aspect. Since the main structure of the atomizer assembly 1 has been described in detail in the first aspect, its contents are included herein and will not be repeated here.

[0077] The atomizer may also include a main body having a compressor for generating compressed air.

[0078] The above description only describes the configuration of the atomizer in the embodiments of this application. This application is not limited to this. The atomizer may also include other conventional configurations. For details, please refer to the relevant technology. The description is omitted here.

[0079] According to the nebulizer of this application embodiment, the suction tube 20 is closer to the first side wall 1041 of the wall 104, which is a non-linear structure, relative to the second side wall 1042 of the wall 104. The first side wall 1041 of the wall 104 is formed to clamp the external air inlet tube 302 in a non-linear structure. That is, the first side wall 1041 of the wall 104 is formed to bend towards the external air inlet tube 302 in a non-linear structure. Therefore, even when the nebulizer assembly 1 is in a horizontal position, the liquid can be drawn through the suction tube 20. At the same time, a part of the inner surface of the first side wall 1041 of the wall 10 of the cup body 10 is tightly fitted with a part of the outer surface of the external air inlet tube 302. In this way, even when the nebulizer assembly 1 is in a horizontal position, the liquid will not flow out of the cup body 10, thereby avoiding waste of the liquid. Furthermore, by placing the suction tube 20 closer to the first sidewall 1041 of the wall 104 relative to the second sidewall 1042 of the wall 104, it is easier to filter out large particles generated by atomization, which helps to reduce the particle size and thus makes it easier for patients to absorb the atomized gas.
