Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a nebulizer. Background Technology

[0002] Nebulized inhalation therapy is now an important and effective treatment method for respiratory diseases. It uses a nebulizer to atomize medication into tiny particles, which are then inhaled and deposited in the respiratory tract and lungs, achieving painless, rapid, and effective treatment. It can be used to relieve or treat various upper and lower respiratory system diseases, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis, and other diseases occurring in the trachea, bronchi, alveoli, and pleural cavity.

[0003] However, existing ultrasonic nebulizers use ultrasound to atomize liquids, and the atomized liquids are evenly dispersed into the air. Most of the particles can only be deposited in the upper respiratory tract, such as the mouth and throat. The amount entering and depositing in the lungs is very small, so the effect on small respiratory diseases is very small, resulting in insufficient drug utilization. Summary of the Invention

[0004] The purpose of this invention is to provide a nebulizer that addresses the problem of insufficient drug utilization in existing ultrasonic nebulizers.

[0005] This invention provides a nebulizer, comprising: a nebulizer body and a mask connected to the nebulizer body. The nebulizer body is provided with an exhaust channel, a nebulizing component, a nebulizing cup, and a sensing device. The nebulizing component is connected to the nebulizing cup, and the sensing device is disposed in the exhaust channel and electrically connected to the nebulizing component. The mask is provided with at least one inhalation port. The nebulizing component is used to atomize the liquid medicine in the nebulizing cup and introduce it into the mask. The sensing device is used to detect the breathing state and send a sensing signal to the nebulizing component when exhalation is detected, so that the nebulizing component stops nebulizing according to the sensing signal.

[0006] Furthermore, the sensing device includes a drive plate and a detection sensor for sensing the movement of the drive plate, wherein the drive plate is movably disposed in the exhaust channel and the detection sensor is disposed corresponding to the drive plate.

[0008] Furthermore, the mounting block is a U-shaped mounting block, with the bottom of the U-shaped mounting block arranged along the axial cross-section of the exhaust channel. A vent hole is provided at the bottom of the U-shaped mounting block. One end of the drive plate is movably mounted on one side of the U-shaped mounting block. A detection sensor located at the front or rear end of the drive plate in the exhalation direction is mounted on the bottom of the U-shaped mounting block, and a detection sensor located at the other end of the drive plate is mounted on the other side of the U-shaped mounting block and is arranged opposite to the other end of the drive plate.

[0009] Furthermore, the inhalation port is provided with an air-isolating plate, which is used to close during exhalation and open during inhalation.

[0010] Furthermore, the atomizing component includes: an electric control board and an atomizing plate electrically connected to the electric control board, the outlet of the atomizing cup is provided with a through hole, the atomizing plate is disposed in the through hole, and the electric control board is disposed in the atomizer body.

As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0033] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0034] Please see Figure 1-5This invention provides a nebulizer, comprising: a nebulizer body 1 and a mask 2 connected to the nebulizer body 1. The nebulizer body 1 is provided with an exhaust channel 3, a nebulizing component 4, a nebulizing cup 5, and a sensing device 6. The nebulizing component 4 is connected to the nebulizing cup 5. The sensing device 6 is disposed in the exhaust channel 3 and electrically connected to the nebulizing component 4. The mask 2 is provided with at least one inhalation port 7. The nebulizing component 4 is used to atomize the liquid medicine in the nebulizing cup 5 and introduce it into the mask 2. The sensing device 6 is used to detect the breathing state and send a sensing signal to the nebulizing component 4 when exhalation is detected, so that the nebulizing component 4 stops atomizing according to the sensing signal.

[0035] The working principle of the nebulizer is as follows: When the sensor device 6 detects the user's exhalation, it sends a sensing signal to the nebulization component 4, causing the nebulization component 4 to stop nebulizing according to the sensing signal. All the gas exhaled by the user is discharged through the exhaust channel 3. When the sensor device 6 detects the user's inhalation, it sends a sensing signal to the nebulization component 4, causing the nebulization component 4 to start nebulizing according to the sensing signal. At this time, the nebulized medicine entering the mask 2 can be inhaled by the user with the inhalation, thereby acting on the small respiratory tract.

[0036] The sensing device 6 will be described in detail below:

[0037] Please see Figure 6 and 7 The sensing device 6 includes a drive plate 8 and a detection sensor 9 for sensing the movement of the drive plate 8. The drive plate 8 is movably disposed in the exhaust channel 3, and the detection sensor 9 is disposed corresponding to the drive plate 8.

[0038] In one embodiment, the drive plate 8 is arranged along the axial cross-section of the exhaust channel 3, that is, the drive plate 8 is arranged perpendicular to the gas flow direction. A mounting block 10 is provided in the exhaust channel 3. One end of the drive plate 8 is movably mounted on the mounting block 10. At least two detection sensors 9 are provided, one of which is located at the front or rear end of the drive plate 8 in the exhalation direction, and the other is located at the other end of the drive plate 8.

[0039] The working principle of the sensing device 6 is as follows: When the gas flows to the position of the driving plate 8, since the driving plate 8 is set perpendicular to the gas flow direction, the driving plate 8 shakes back and forth under the force of the gas. At this time, the detection sensor 9 located at the other end of the driving plate 8 senses the shaking of the driving plate 8 and determines that the user is using it. Then, the detection sensor 9 located at the front end of the driving plate 8 in the exhalation direction determines whether it is an exhalation state or an inhalation state. For the detection sensor 9 located at the front end of the driving plate 8 in the exhalation direction, when it senses that the distance of the driving plate 8 increases, it determines that it is an inhalation state, and when it senses that the distance of the driving plate 8 decreases, it determines that it is an exhalation state. The detection sensor 9 located at the rear end of the driving plate 8 in the exhalation direction has the opposite determination method as the detection sensor 9 located at the front end of the driving plate 8 in the exhalation direction.

[0040] It should be noted that only one detection sensor 9 can be set, that is, it can be set at the front or rear end of the driving plate 8 in the direction of exhalation, that is, no detection sensor 9 is set at the other end of the driving plate 8; the breathing state can also be sensed by the driving plate 8 alone. The driving plate 8 is a strain gauge. The strain gauge will produce corresponding deformation with the flow of gas. Since the resistance value of the strain gauge will change when it deforms, and the resistance value can change accordingly with the magnitude of the deformation, the user's breathing state can be determined based on the resistance value of the strain gauge.

[0041] Among them, the detection sensor 9 can be a photoelectric sensor, such as an infrared sensor or an ultraviolet sensor, or it can be an ultrasonic sensor.

[0042] Specifically, the mounting block 10 is a U-shaped mounting block 10. The bottom of the U-shaped mounting block 10 is set along the axial cross-section of the exhaust channel 3. A vent hole 11 is provided at the bottom of the U-shaped mounting block 10. One end of the drive plate 8 is movably mounted on one side of the U-shaped mounting block 10. The detection sensor 9 located at the front or rear end of the drive plate 8 in the exhalation direction is mounted on the bottom of the U-shaped mounting block 10. The detection sensor 9 located at the other end of the drive plate 8 is mounted on the other side of the U-shaped mounting block 10 and is set opposite to the other end of the drive plate 8.

[0043] In one embodiment, the mounting block 10 is a U-shaped mounting block 10. The bottom of the U-shaped mounting block 10 is arranged along the axial cross-section of the exhaust channel 3. The bottom of the U-shaped mounting block 10 is provided with a vent hole 11 corresponding to the exhaust channel 3. One end of the drive plate 8 is movably mounted on the side of the U-shaped mounting block 10 away from the vent hole 11 by screws. The detection sensor 9 located at the front or rear end of the drive plate 8 in the exhalation direction is mounted on the bottom of the U-shaped mounting block 10. The detection sensor 9 located at the other end of the drive plate 8 is mounted on the other side of the U-shaped mounting block 10 and is arranged opposite to the other end of the drive plate 8. The fact that one end of the drive plate 8 is arranged away from the vent hole 11 and the other end of the drive plate 8 is arranged corresponding to the vent hole 11 allows the drive plate 8 to produce a larger deformation under the same force, and the drive plate 8 can more accurately reflect the flow state of the gas.

[0044] For further details, please refer to Figure 1 An isolation plate 12 is provided on the inhalation port 7, which is used to close during exhalation and open during inhalation. The isolation plate 12 allows more gas to pass through the mask into the human body during inhalation, that is, more medicine can enter the human body during inhalation and act more effectively on the small respiratory tracts of the human body. The isolation plate 12 also allows gas to be discharged through the exhaust channel 3 during exhalation, which has a greater force on the drive plate 8 and can better reflect the state of the gas during exhalation, so as to better stop nebulization and improve the utilization rate of the medicine.

[0045] Furthermore, the structure of the isolation gas strip 12 can be a conical structure composed of several rotating parts. When inhaling, under the action of the gas, the several rotating parts rotate outward and separate from each other. When exhaling, the several rotating parts rotate inward under the drive of the gas and come into close contact with each other, thereby preventing the gas from flowing out through the inhalation port 7. The isolation gas strip 12 can also be set inside the mask 2, and at one end near the opening of the mask 2 (i.e., the end closest to the user) it is rotatably connected to the mask 2 through a connector. When inhaling, under the push of the gas, the isolation gas strip 12 rotates inward and forms an opening, and the gas enters the mask 2 through the opening. When exhaling, under the push of the gas, the isolation gas strip 12 rotates outward and comes into contact with the mask 2, so as to prevent the gas from flowing out through the inhalation port 7.

[0046] The following is a description of atomizing component 4:

[0047] Please see Figure 8 The atomizing component 4 includes an electric control board 13 and an atomizing plate 14 electrically connected to the electric control board 13. The outlet of the atomizing cup 5 is provided with a through hole, and the atomizing plate 14 is disposed in the through hole. The electric control board 13 is disposed in the atomizer body 1. The atomizing plate 14 is an ultrasonic atomizing plate 14.

[0048] The electric control board 13 and the atomizing plate 14 can be electrically connected via spring pin 15. When the electric control board 13 receives the atomization command, it controls the atomizing plate to start atomizing.

[0049] Please see Figure 4-9 The atomizer body 1 includes: an atomizing nozzle 16, a first air hole 17 communicating with the outlet of the atomizing cup 5 on one side of the atomizing nozzle 16, and a mask 2 covering the atomizing nozzle 16 on one side; a second air hole 18 communicating with the first air hole 17 is also provided on one side of the atomizing nozzle 16, and a third air hole 19 is provided at the end of the atomizer body 1 away from the atomizing nozzle 16, and an exhaust channel 3 is provided between the second air hole 18 and the third air hole 19.

[0050] The atomizer body 1 includes: a housing 20, and an atomizing cup 5 detachably connected to the upper part of the housing 20.

[0051] Specifically, a limiting block is provided on the outer side of the housing 20, and a limiting hole is provided on the inner side of the atomizing cup 5 to cooperate with the limiting block, and the limiting block can slide within the limiting hole. Alternatively, a limiting hole is provided on the outer side of the housing 20, and a limiting block is provided on the inner side of the atomizing cup 5 to cooperate with the limiting hole, and the limiting block can slide within the limiting hole. The design of the limiting block and the limiting hole achieves vertical restriction of the atomizing cup 5 relative to the housing 20. A locking member 21 is also provided on the upper part of the housing 20 (e.g., Figure 10As shown, the locking member 21 is provided with a lock head 22, and the atomizing cup 5 is provided with a lock hole that cooperates with the lock head 22. When the lock head 22 is inserted into the lock hole, the atomizing cup 5 cannot move left or right relative to the housing 20. In this embodiment, the design of the limiting block, the limiting hole and the locking member 21 makes the atomizing cup 5 detachably connected to the housing 20, which is convenient for disassembly and transportation.

[0052] Furthermore, a button is provided on the locking member 21. When the button is pressed, the locking head 22 will retract into the atomizing cup 5. At this time, the atomizing cup 5 can be separated from the housing 20 by moving left and right.

[0053] Furthermore, the locking head 22 is arranged in an arc shape or at an angle, and the end of the locking head 22 closer to the mask 2 is lower than the end farther away from the mask 2. When the atomizing cup 5 is installed on the housing 20, there is no need to press the button to make the locking head 22 retract into the atomizing cup 5 first. During the installation process, the locking head 22 will gradually retract into the atomizing cup 5 under the action of the thrust.

[0054] The atomizing cup 5 and the housing 20 can also be detachably connected by screws.

[0055] Please see Figure 11 To facilitate medication filling, the top of the nebulizer cup 5 in this embodiment is provided with a cup lid 23. One side of the cup lid 23 is hinged to one side of the top of the nebulizer cup 5, and a fastening member 24 is rotatably provided on the other side of the cup lid 23. A mating block 25 is provided extending outward from the other side of the top of the nebulizer cup 5. The fastening member 24 is provided with a mating hole 26 for fastening the mating block 25. When medication is to be filled, the fastening member 24 can be opened. After the medication is filled, the fastening member 24 can be fastened onto the mating block 25.

[0056] Furthermore, the atomizer body 1 also includes a battery compartment 27 for installing batteries.

[0057] Furthermore, the atomizer body 1 is also equipped with a control component 28, which can be a PCB, used to control the atomizer to turn on and off.

[0058] Furthermore, a sealing element 29 is provided between the atomizing plate 14 and the atomizing nozzle 16 to prevent the liquid medicine in the atomizing cup 5 from leaking out at will.

[0059] The housing 20 in this embodiment also includes a front housing 30 and a rear housing 31, which make the atomizer easy to disassemble and maintain.
