Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a medicine cup, an integrated nebulizer assembly, and a nebulizer. Background Technology

[0002] Nebulizers can convert liquid medications into tiny aerosol particles, allowing the medication to act directly on the patient's respiratory tract and lungs through inhalation. This helps to moisturize the airways, thin sputum, and relieve coughs and asthma, and is widely used in the prevention and adjunctive treatment of respiratory diseases.

[0003] Currently, nebulizers generally include components such as a main unit, a medication cup unit, an atomizing plate unit, an inlet one-way valve, a reservoir, a mouthpiece, and a breathing mask. When the user inhales through the mouthpiece or breathing mask, the inlet one-way valve opens, and the liquid medication in the medication cup unit is atomized into an aerosol by the atomizing plate unit and smoothly enters the patient's respiratory tract. Conversely, when the user exhales, the inlet one-way valve closes to prevent the medication from being exhaled, improving drug delivery efficiency and preventing backflow that could cause biocontamination and medication waste.

[0004] The medication cup unit is the container for holding the nebulized medication. It precisely controls the amount of medication administered in a single nebulization, ensuring a continuous and stable release of the drug during nebulization and providing the material basis for subsequent nebulizations. During use, the medication from the vial needs to be poured into the medication cup unit. However, in practical applications, due to the small opening of the vial, it is difficult to smoothly and completely pour the medication into the medication cup unit. This not only affects the user experience but also easily leads to medication waste and reduces the therapeutic effect.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0006] To address or improve to some extent the technical problem of difficulty in smoothly and completely injecting liquid medicine into a medicine cup unit in existing technologies, this utility model provides a medicine cup. The medicine cup includes a storage chamber having opposing inlet and outlet ports. A guide rib extending towards the inlet is provided within the storage chamber. The inlet is configured to allow the mouth of a medicine bottle to be inserted into the storage chamber, and the guide rib is configured to extend into the mouth of the bottle, allowing the liquid medicine in the medicine bottle to flow along the guide rib into the storage chamber.

[0007] Those skilled in the art will understand that the present invention's medicine cup includes a storage chamber. The storage chamber has a corresponding inlet and outlet. The inlet can be fitted with the mouth of a medicine bottle, allowing the bottle's mouth to extend into the storage chamber; the outlet is used to discharge the medicine flowing into the storage chamber for use with other components (such as an atomizing unit). A guide rib extending towards the inlet is also provided within the storage chamber. In the assembled state, the guide rib extends into the mouth of the medicine bottle, allowing the medicine inside the bottle to flow smoothly and completely into the storage chamber along the guide rib. Therefore, the present invention's medicine cup can significantly improve the efficiency of liquid dispensing, enhance the user experience, avoid medicine waste, and ensure therapeutic efficacy.

[0008] In the preferred embodiment of the above-mentioned liquid medicine cup, the liquid medicine cup includes: a mounting plate extending vertically, wherein the mounting plate has a liquid outlet; and an arc-shaped plate disposed on one side of the mounting plate, the arc-shaped plate and the mounting plate together forming the liquid storage cavity. The mounting plate and the arc-shaped plate facilitate the formation of the liquid storage cavity. Furthermore, the liquid outlet is disposed on the mounting plate extending approximately vertically, which facilitates processing.

[0009] In the preferred embodiment of the above-described medicine cup, the plane containing the liquid inlet is perpendicular to the mounting plate. This arrangement ensures that the plane containing the liquid inlet extends approximately horizontally to accommodate an inverted medicine bottle that extends approximately vertically.

[0010] In the preferred embodiment of the above-mentioned medicine cup, the cross-section of the liquid storage cavity gradually decreases along the vertically downward direction. This design allows the medicine to flow smoothly under its own gravity, reducing drug residue.

[0011] In the preferred embodiment of the above-mentioned liquid cup, the bottom of the liquid storage chamber is flush with the bottom of the liquid outlet to further reduce drug residue.

[0012] In the preferred embodiment of the above-mentioned liquid medicine cup, the guide rib extends from the arc plate in a direction perpendicular to the mounting plate, so that the liquid medicine flowing into the storage cavity can flow smoothly to the outlet arranged on the mounting plate, and will not stagnate in the gap between the guide rib and the arc plate.

[0013] In the preferred embodiment of the above-mentioned medicine cup, the vertical plane containing the guide ribs coincides with or is parallel to the vertical plane passing through the center of the outlet. This arrangement allows the guide ribs to roughly bisect or evenly divide the outlet, ensuring that the medicine flows uniformly towards the outlet.

[0014] In the preferred embodiment of the above-mentioned medicine cup, the cross-section of the guide rib gradually decreases along the direction close to the liquid inlet, so that the guide rib has a roughly conical structure, which facilitates the flow of medicine.

[0015] In the preferred embodiment of the above-mentioned medicine cup, an annular protrusion is provided in the liquid storage cavity near the liquid inlet and extending radially inward along the liquid inlet. In the assembled state, the annular protrusion is adapted to engage with the bottle opening. This design allows the medicine bottle to be conveniently and stably fixed at the liquid inlet.

[0016] In the preferred embodiment of the above-mentioned medicine cup, a limiting rib is further provided in the liquid storage cavity on the side of the annular protrusion away from the liquid inlet, so that the bottle mouth can abut against the limiting rib in the assembled state. This design conveniently limits the position of the medicine bottle, allowing it to be accurately inserted into the predetermined position of the liquid storage cavity.

[0017] In the preferred embodiment of the above-mentioned medicine cup, the medicine bottle is a vial. Vials are commonly used containers for nebulization therapy, possessing advantages such as good sealing performance, chemical stability, low-temperature tolerance, low adsorption, and transparent visibility.

[0018] To address or improve to some extent the technical problem of difficulty in smoothly and completely injecting liquid medicine into the liquid medicine cup unit in existing technologies, this utility model provides an integrated atomizing component. The integrated atomizing component includes: a mist storage tank having opposing mist inlets and outlets; an air inlet one-way valve connected to the mist storage tank and disposed at the mist inlet to control the opening and closing of the mist inlet; and a liquid medicine cup according to any of the above, located on the side of the air inlet one-way valve away from the mist inlet, and rotatably disposed on the mist storage tank.

[0019] To address or improve upon the technical problems in the prior art to a certain extent, this utility model provides an atomizer. The atomizer includes a medicine cup according to any of the above claims, or an integrated atomizing assembly according to the above claims. Attached Figure Description

[0034] To address or improve to some extent the technical problem of difficulty in smoothly and completely injecting liquid medicine into the liquid medicine cup unit in the prior art, this utility model provides a liquid medicine cup 30. The liquid medicine cup 30 includes a liquid storage chamber 33, which has a liquid inlet 331 and a liquid outlet 332. A guide rib 34 extending toward the liquid inlet 331 is provided in the liquid storage chamber 33. The liquid inlet 331 is configured to allow the bottle mouth 22 of the medicine bottle 2 to be inserted into the liquid storage chamber 33, and the guide rib 34 is configured to extend to the bottle mouth 22, so that the liquid medicine in the medicine bottle 2 can flow into the liquid storage chamber 33 along the guide rib 34.

[0035] Figure 1 This is a first structural schematic diagram of an embodiment of the medicine cup of this utility model; Figure 2 This is a second structural schematic diagram of an embodiment of the medicine cup of this utility model; Figure 3 This is a third structural schematic diagram of an embodiment of the medicine cup of this utility model; Figure 4 This is a top view of an embodiment of the medicine cup of this utility model; Figure 5 This is an embodiment of the medicine cup of this utility model. Figure 4 The sectional view obtained by the BB section line shown. Figures 1-5 As shown, in one or more embodiments, the medicine cup 30 of this utility model includes a liquid storage cavity 33, which has a liquid inlet 331 and a liquid outlet 332. The liquid inlet 331 allows the mouth 22 of the medicine bottle 2 to be inserted into the liquid storage cavity 33. A guide rib 34 extending towards the liquid inlet 331 is provided in the liquid storage cavity 33, such that in the assembled state, the guide rib 34 can extend into the mouth 22 of the medicine bottle 2 (see...). Figure 8This allows the liquid in the medicine bottle 2 to flow smoothly and completely into the storage chamber 33 along the guide rib 34. The medicine bottle 2 can be a vial or other suitable medicine bottle. Therefore, the medicine cup 30 of this invention can significantly improve the efficiency of liquid injection, enhance the user experience, avoid liquid waste, and ensure the therapeutic effect.

[0036] like Figures 1-5 As shown, in one or more embodiments, the medicine cup 30 of this utility model includes a mounting plate 31 extending generally in a vertical direction and an arc-shaped plate 32 arranged on one side of the mounting plate 31. The mounting plate 31 has opposing first sides 31a and second sides 31b. Based on Figure 1 As shown in the orientation diagram, the first side 31a is the front side of the mounting plate 31, and the second side 31b is the rear side of the mounting plate 31. An arc-shaped plate 32 is arranged on the first side 31a of the mounting plate 31. The mounting plate 31 and the arc-shaped plate 32 together form a hollow liquid storage cavity 33. In one or more embodiments, a liquid outlet 332 is arranged on the mounting plate 31. Based on... Figure 1 As shown, the outlet 332 faces forward. In one or more embodiments, the plane containing the inlet 331 is substantially perpendicular to the mounting plate 31. Based on Figure 1 As shown, the inlet 331 opens upwards. The plane containing the inlet 331 is horizontal, while the mounting plate 31 extends approximately vertically. In one or more embodiments, the cross-section of the reservoir 33 gradually decreases in the vertically downward direction, allowing the liquid medicine within the reservoir 33 to flow smoothly under its own gravity, reducing drug residue. Furthermore, the bottom of the reservoir 33 is flush with the bottom of the outlet 332 to further reduce drug residue.

[0037] See also Figure 5 In one or more embodiments, the guide rib 34 is configured to extend from the arcuate plate 32 in a direction perpendicular to the mounting plate 31. Based on Figure 1 As shown, the guide rib 34 extends from the arc-shaped plate 32 in a generally front-to-back direction. This creates a small clamping space between the guide rib 34 and the arc-shaped plate 32, preventing the liquid in the storage cavity 33 from becoming stagnant within this space, thus keeping the liquid within the storage cavity 33. Furthermore, the vertical plane containing the guide rib 34 coincides with the vertical plane passing through the center of the outlet 332. In other words, the vertical plane containing the guide rib 34 roughly bisects the outlet 332, allowing the liquid in the storage cavity 33 to flow evenly to the outlet 332 under the guidance of the guide rib 34, ensuring uniform atomization. Alternatively, the vertical plane containing the guide rib 34 can also be parallel to the vertical plane passing through the center of the outlet 332. In one or more embodiments, the cross-section of the guide rib 34 gradually decreases towards the inlet 331. Figure 1As shown in the diagram, the cross-section of the guide rib 34 gradually decreases along the vertically upward direction. Therefore, the guide rib 34 has a roughly conical structure, which facilitates the flow of the liquid medicine.

[0038] See also Figure 5 In one or more embodiments, an annular protrusion 35 is provided in the liquid storage cavity 33 near the liquid inlet 331. This annular protrusion 35 extends radially inward along the liquid inlet 331. In other words, the diameter of the annular protrusion 35 is smaller than the diameter of the liquid inlet 331. The annular protrusion 35 is provided so that, in the assembled state, the bottle mouth 22 of the medicine bottle 2 can engage with the annular protrusion 35, thus stably and firmly fixing the medicine bottle 2 to the liquid inlet 331.

[0039] See also Figure 5 In one or more embodiments, a limiting rib 36 is further provided in the liquid storage cavity 33 on the side of the annular protrusion 35 away from the liquid inlet 331. Based on Figure 5 As shown, the limiting rib 36 is located below the annular protrusion 35. In the assembled state, the mouth 22 of the medicine bottle 2 can abut against the limiting rib 36, allowing the medicine bottle 2 to be accurately inserted into the predetermined position of the liquid storage cavity 33, achieving rapid and accurate positioning.

[0040] See also Figure 1 and Figure 2 In one or more embodiments, the mounting plate 31 is provided with electrode through holes 311 located on the left and right sides of the liquid outlet 332, respectively. Each electrode through hole 311 allows the corresponding flexible electrode 14 on the main unit 10 of the atomizer 1 (see...) Figure 8 It is inserted therein so as to form an electrical connection with the corresponding flexible electrical connector (not shown in the figure) on the atomizing plate unit 60.

[0041] See also Figure 1 and Figure 2 In one or more embodiments, the mounting plate 31 is provided with four air guide holes 312 spaced apart from each other circumferentially along the outlet 332. Each air guide hole 312 has a generally rectangular shape with rounded corners. The air guide holes 312 are arranged to connect the main air inlet 371 on the circumferential annular wall 37 and the air inlet check valve 40. It should be noted that the number, shape and arrangement of the air guide holes 312 can be adjusted according to actual needs.

[0042] See also Figure 1 In one or more embodiments, the curved plate 32 of the medicine cup 30 is further provided with a generally vertical orientation toward the direction away from the mounting plate 31 (based on...). Figure 1 The connecting rib 313 extends in the direction shown (i.e., backward). The connecting rib 313 is provided to facilitate a fixed connection with the main unit 10 of the atomizer 1.

[0043] See also Figure 1 In one or more embodiments, two positioning ribs 314 spaced apart from each other in the left-right direction are further provided on the first side 31a of the mounting plate 31. Correspondingly, a positioning groove 111 is provided on the housing 11 of the main unit 10 to allow the two positioning ribs 314 to be inserted therein (see...). Figure 8 The positioning ribs 314 and positioning grooves 111 improve the accuracy and efficiency of positioning and installation between the liquid cup 30 and the main unit 10. It should be noted that the number, shape, and arrangement of the positioning ribs 314 and positioning grooves 111 can be adjusted according to actual needs.

[0044] See also Figure 1 In one or more embodiments, guide ribs 315 spaced apart from each other in the left-right direction are further provided on the first side 31a of the mounting plate 31. Correspondingly, a guide groove (not shown in the figure) is provided on the housing 11 of the main unit 10, allowing each guide rib 315 to be inserted therein. The arrangement of the guide ribs 315 and the guide groove can further improve the reliability of the connection between the medicine cup 30 and the main unit 10. It should be noted that the number, shape, and arrangement of the guide ribs 315 and the guide groove can also be adjusted according to actual needs.

[0045] See also Figure 2 In one or more embodiments, a plurality of snap-fit ​​ribs 316 spaced apart from each other are provided on the second side 31b of the mounting plate 31. In the assembled state, the atomizing plate unit 60 can snap onto the plurality of snap-fit ​​ribs 316, achieving a fast and efficient snap-fit ​​connection. It should be noted that the number, shape, and arrangement of the snap-fit ​​ribs 316 can also be adjusted according to actual needs.

[0046] See also Figure 1 and Figure 2 In one or more embodiments, the medicine cup 30 further includes a circumferential annular wall 37 surrounding the mounting plate 31. In one or more embodiments, a main air inlet 371 is provided on the side of the circumferential annular wall 37 located on the mounting plate 31 away from the air inlet check valve 40 (i.e., the first side 31a). Based on Figure 1 As shown, the main air inlet 371 is located on the rear side of the mounting plate 31 within the circumferential wall 37. The main air inlet 371 has a generally circular shape or other suitable shape. The number and arrangement of the main air inlets can be adjusted according to actual needs. In this way, external air can sequentially enter the mist reservoir 50 through the main air inlet 371, the air guide hole 312 on the mounting plate 31, and the one-way air inlet valve 40, thereby causing the airflow to carry tiny drug particles to form an aerosol.

[0047] See also Figure 1 and Figure 2In one or more embodiments, an auxiliary air intake port 372 is provided on the side of the circumferential ring wall 37 located on the mounting plate 31 near the intake check valve 40. Based on Figure 1 As shown, the auxiliary air inlet 372 is located on the front side of the mounting plate 31 within the circumferential wall 37. The auxiliary air inlet 372 has a generally rectangular shape with rounded corners. The number and arrangement of the auxiliary air inlets 372 can be adjusted according to actual needs. The auxiliary air inlets 372 allow external air to enter the mist reservoir 50 sequentially through the auxiliary air inlets 372 and the one-way air inlet valve 40, increasing the amount of air entering the mist reservoir 50 and improving drug delivery efficiency.

[0048] See also Figure 1 and Figure 2 In one or more embodiments, approximately semi-circular clearance openings 373 are also provided on the left and right sides of the circumferential ring wall 37. Based on Figure 1 As shown, the opening of each clearance port 373 faces forward. In the assembled state, the gripping walls (not shown in the figure) on the left and right sides of the atomizing plate unit 60 can be inserted into the corresponding clearance ports 373 respectively.

[0049] See also Figure 2 In one or more embodiments, a first bearing (not shown in the figure) is rotatably arranged on the circumferential ring wall 37 and mounted on the mist reservoir 50, so that the entire liquid cup 30 can be easily rotated relative to the mist reservoir 50. Based on Figure 2 As shown, the first bearing is located at the lower part of the circumferential ring wall 37.

[0050] See also Figures 1-3 In one or more embodiments, the liquid container 30 further includes a connecting tongue 38 connected to the circumferential annular wall 37. The connecting tongue 38 is provided with a snap-fit ​​block 53 on the mist reservoir 50 (see...). Figure 6 and Figure 7 A snap-fit ​​hole 381 is formed to create a snap-fit ​​connection. The snap-fit ​​hole 381 and the snap-fit ​​block 53 allow the medicine cup 30 to be easily and detachably connected to the mist reservoir 50. In one or more embodiments, the connecting tongue 38 is configured to extend obliquely toward the mist reservoir 50 from the circumferential annular wall 37. This obliquely positioned connecting tongue 38 makes it easier for the snap-fit ​​block 53 to be inserted into the snap-fit ​​hole 381.

[0051] Figure 6 This is a schematic diagram of the structure of an embodiment of the atomizer of this utility model; Figure 7 This is a top view of an embodiment of the atomizer of this utility model; Figure 8 This is an embodiment of the atomizer of the present invention. Figure 7 The sectional view obtained by the BB section line shown. Figures 6-8As shown, in one or more embodiments, the atomizer 1 of this utility model includes a main unit 10, an integrated atomizing component 20, and an atomizing plate unit 60. The integrated atomizing component 20 includes the medicine cup 30, the one-way air inlet valve 40, and the mist reservoir 50 described in any of the above embodiments. It should be noted that the atomizer 1 of this utility model can also be configured to include the medicine cup 30 described in any of the above embodiments, and the medicine cup 30 can be matched with other suitable components.

[0052] See also Figures 6-8 In one or more embodiments, the main unit 10 and the medicine cup 30 are detachably connected. Specifically, the main unit 10 includes a housing 11, on which a connecting groove for receiving the connecting rib 313 is provided. Further, the main unit 10 also includes a locking mechanism 13 that mates with the connecting rib 313, allowing the connecting rib 313 to switch between a locked position constrained within the connecting groove and an unlocked position detachable from the connecting groove. The specific structure of the locking mechanism 13 is not limited; for example, the locking mechanism 13 may include a push button, a latch connected to the push button, a support plate arranged within the housing 11, and elastic elements connected to the push button and the support plate respectively (not shown in the figure). Correspondingly, a lock hole 3131 is provided on the connecting rib 313. When the connecting rib 313 is inserted into the connecting groove, the lock head on the latch is inserted into the lock hole 3131 on the connecting rib 313, so that the connecting rib 313 is firmly constrained within the connecting groove. At this time, the connecting rib 313 is in the locked position. When the user presses the button, the lock head on the bolt slides out of the lock hole 3131 on the connecting rib 313, and the connecting rib 313 can freely disengage from the connecting groove. At this time, the connecting rib 313 is in the unlocked position.

[0053] See also Figure 8 In one or more embodiments, a positioning groove 111 extending generally in the left-right direction is provided at the front of the housing 11, so that the corresponding positioning rib 314 on the medicine cup 30 can be inserted into the positioning groove 111, thereby improving the accuracy and efficiency of positioning and installation of the medicine cup 30 and the host 10.

[0054] In one or more embodiments, the front of the housing 11 is provided with guide grooves (not shown in the figure) located on the left and right sides respectively, so that the corresponding guide ribs 315 on the medicine cup 30 can be inserted into them respectively, so as to further improve the reliability of the connection between the medicine cup 30 and the host 10.

[0055] See also Figures 6-8In one or more embodiments, a power button 12 and a flexible electrode 14 communicating with the power button 12 are also provided on the top of the housing 11. In the assembled state, the flexible electrode 14 can pass through the corresponding electrode through hole 311 on the medicine cup 30 and form an electrical connection with the atomizing plate unit 60, so that when the power button 12 is turned on, the host 10 can power on the atomizing plate unit 60.

[0056] like Figure 8 As shown, in one or more embodiments, the integrated atomizing component 20 of this utility model includes a mist storage tank 50, an air inlet one-way valve 40, and a medicine cup 30. The mist storage tank 50 has opposing mist inlets 51 and mist outlets 52; the air inlet one-way valve 40 is connected to the mist storage tank 50 and arranged at the mist inlet 51 to control the opening and closing of the mist inlet 51; the medicine cup 30 is located on the side of the air inlet one-way valve 40 away from the mist inlet 51, and the medicine cup 30 is rotatably arranged on the mist storage tank 50. Further, the air inlet one-way valve 40 is also rotatably arranged on the mist storage tank 50 and has a rotation axis opposite to the medicine cup 30. Additionally, the atomizing plate unit 60 is detachably arranged on the second side 31b of the mounting plate 31 of the medicine cup 30. In the assembled state, the liquid storage port of the liquid cup 30, the micro-mesh area 61 of the atomizing plate unit 60, the central through hole 41 of the air inlet one-way valve 40, and the mist inlet 51 of the mist storage tank 50 are connected in sequence.

[0057] like Figure 8As shown, when the nebulizer 1 of the present invention is used, the medicine bottle 2 is first opened. Then, the bottle opening 22 is oriented towards the liquid inlet 331 of the liquid cup 30, so that the medicine bottle 2 is inverted in the liquid storage chamber 33. At this time, the bottle body 21 of the medicine bottle 2 is inserted into the liquid inlet 331, and the bottle opening 22 of the medicine bottle 2 abuts against the limiting rib 36 in the liquid storage chamber 33, achieving rapid and precise positioning. Simultaneously, the guide rib 34 in the liquid storage chamber 33 is inserted into the bottle opening 22 of the medicine bottle 2, allowing the liquid medicine in the medicine bottle 2 to flow quickly and completely into the liquid storage chamber 33 along the guide rib 34. Then, the power button 12 on the main unit 10 is turned on, powering the atomizing plate unit 60. During this process, the liquid medicine flows from the outlet 332 to the micro-mesh area 61, generating tiny particles under the action of the atomizing plate unit 60. The atomized medicine enters the mist storage tank 50 through the central through-hole 41 on the air inlet one-way valve 40. Additionally, when the user inhales, the one-way air inlet valve 40 opens, allowing some external air to enter the mist reservoir 50 sequentially through the main air inlet 371, the air guide 312, and the opened one-way air inlet valve 40. Another portion of external air enters the mist reservoir 50 sequentially through the auxiliary air inlet 372 and the opened one-way air inlet valve 40. Inside the mist reservoir 50, the airflow mixes with the atomized drug particles to form an aerosol, which is inhaled into the user's respiratory tract, achieving nebulized therapy. Conversely, when the user exhales, the one-way air inlet valve 40 closes, preventing external air from entering the mist reservoir 50 and the aerosol within it from being exhaled. This improves drug delivery efficiency and prevents backflow of air into the nebulizer unit 60 and the medication cup 30, thus avoiding biocontamination and drug waste.

[0058] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
