Description

Technical Field

[0001] The present invention relates to the technical field of atomization therapy, in particular to an atomizer for auxiliary treatment of children's cough. Background Art

[0002] In nebulization therapy, the selection and use of respiratory components directly affect the treatment effect. When using a mouthpiece, the drug can reach the lower respiratory tract directly through the mouth. Due to the large amount of inhaled air, the deposition rate of the drug in the lungs is higher than that of a breathing mask (for patents related to nebulizers, please refer to CN202223597154.2, a nebulizer with adaptive mist output, and CN202223583420.6, a nebulizer cup with adjustable atomization particles). However, due to their limited understanding ability, children find it difficult to correctly master the use of the mouthpiece and the breathing rhythm, and the actual nebulization effect is often poor.

[0003] In clinical practice, respiratory masks are often used for nebulization for children. However, many children have strong resistance to wearing respiratory masks and often cry loudly. Some parents have cognitive misunderstandings, thinking that children can inhale drugs in large gulps when they cry, but the actual situation is just the opposite: when children cry, their respiratory state is disordered, manifested as long exhalation time and short inhalation time, and at the same time, respiratory secretions increase. The drug is just inhaled and will be exhaled before reaching the lower respiratory tract. Most of the drug only stays in the upper respiratory tract such as the mouth and oropharynx, resulting in a significant decrease in the effectiveness of the medication.

[0004] In fact, whether using a mouthpiece or a respirator, the correct breathing method for nebulization is slow and deep breathing, which ensures that the drug fully reaches and is deposited in the lower respiratory tract. Therefore, for children who have difficulty accurately coordinating their breathing rhythm, there is an urgent need to design a nebulizer that can guide them to form a "slow and deep inhalation" rhythm to solve the problem of insufficient drug efficacy caused by improper breathing coordination during nebulization treatment in children. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems raised in the background technology and to propose an atomizer for auxiliary treatment of children's cough.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A nebulizer for assisting the treatment of children's cough, comprising a main unit, an nebulizer cup, a breathing adjustment assembly, and a breathing piece. An air connection pipe, a liquid medicine pool, an atomizer core, a mist outlet pipe, and an nebulizer cup cover are arranged vertically from bottom to top inside the nebulizer cup. The main unit is connected to the air connection pipe via a first hose for providing compressed air. A breathing piece is installed at the end of the mist outlet pipe, and the breathing adjustment assembly is installed between the breathing piece and the nebulizer pipe.

[0008] The breathing adjustment component includes an adjustment control unit and a guide unit. The guide unit is equipped with an airflow sensor for monitoring the breathing direction and airflow volume, and a guide vane for guiding the airflow direction. The adjustment control unit is equipped with a control vane for adjusting the inhalation resistance. The control vane can adjust its own spatial posture according to the signal feedback from the airflow sensor to increase or decrease the breathing resistance.

[0009] As a further solution of the present invention: the upper part of the air receiving pipe is located inside the atomizing cup, and its diameter gradually decreases and becomes conical as it goes up. At the same time, a nozzle is provided on the top of the air receiving pipe, and a mist-forming baffle is provided above the nozzle;

[0010] The upper part of the atomizing core is a mist gathering section, and the lower part is a siphon section, wherein the siphon section is sleeved on the upper part of the air connecting pipe, and a water absorption channel is provided in the siphon section. The bottom of the water absorption channel is connected to the liquid medicine pool, and the top is close to the nozzle of the air connecting pipe.

[0011] As a further embodiment of the present invention, the adjustment control is cylindrical in shape, with a center block provided at the center thereof, and the regulating blade is a flat blade in the shape of a fan, with an inner edge fixedly connected to the center block and an outer edge fixedly connected to the adjustment control;

[0012] There are multiple regulating blades distributed in a circular array in the regulating control unit. A fan-shaped telescopic portion is provided on the side of each regulating blade. At the same time, an air inlet is provided on the outside of the regulating control unit. The air inlet is connected to the main unit through a second hose. The air inlet is used to fill gas into the fan-shaped telescopic portion to make it expand and unfold.

[0013] As a further solution of the present invention: a cavity is provided on the side of the regulating blade, a spring is installed in the cavity, the spring is connected to the movable plate, the outer side of the movable plate is covered with an elastic membrane, the edge of the elastic membrane is fixedly connected to the inner wall of the cavity to form a sealed fan-shaped telescopic part, and the fan-shaped telescopic part is connected to the air inlet.

[0014] As a further solution of the present invention: the guide blades are distributed in a spiral shape inside the guide member, and the spiral structure guides the airflow along a preset path to prevent the mist from forming a turbulent flow inside the guide member.

[0015] As a further solution of the present invention: the guide blades are provided in 4-8 pieces and distributed in a circular array along the inner wall of the guide member. The guide blades have an overall arc-shaped curved surface structure, and the blade width gradually decreases from the air inlet end to the air outlet end. The angle between the guide blades and the axis of the guide member is 15°-30°, and the spiral direction of all guide blades is consistent.

[0016] As a further solution of the present invention: the host is provided with a display screen, which dynamically displays animated images of inhalation and exhalation, and simultaneously emits inhalation sounds and exhalation sounds through an audio playback device.

[0017] As a further solution of the present invention: the breathing piece is a mouthpiece or a breathing mask;

[0018] The breathing piece is provided with an exhalation port, and an exhalation valve, a one-way valve or a one-way diaphragm is installed at the position of the exhalation port.

[0019] As a further solution of the present invention: the nozzle is provided with a flow regulating valve, and the mist gathering section is provided with a baffle on a side close to the mist outlet pipe.

[0020] As a further solution of the present invention: the adjustment control is installed on a side close to the mist outlet pipe and is fixedly connected to the mist outlet pipe, and the flow guide is installed on a side close to the breathing piece and is fixedly connected to the breathing piece;

[0021] When all the fan-shaped telescopic parts are in the fully expanded state, they will block the cross section of the adjustment control.

[0022] Compared with the existing technology, the advantages of the present invention are: on the one hand, dynamic guidance of the child's breathing state is achieved through the breathing adjustment component, the airflow sensor in the guide piece can monitor the breathing state, and the control blades in the adjustment component can adjust their posture according to the monitoring signal to change the breathing resistance, guiding the child to form a "slow and deep inhalation" rhythm, and solving the problem of low drug deposition rate caused by improper breathing coordination; at the same time, the display screen of the host converts the abstract breathing rhythm into an intuitive audio-visual signal through animation, helping to guide children to imitate the standard "slow and deep inhalation" rhythm.

[0023] On the other hand, the spiral guide blades inside the guide can guide the mist to flow along a preset path, avoiding turbulence and overcoming the problem of drug residue in the upper respiratory tract caused by turbulence. At the same time, the spiral acceleration effect can push the mist particles directly into the deep respiratory tract, avoiding drug retention in the oropharynx, and significantly improving the drug efficacy in children's lungs. In addition, the design of the exhalation port discharges the exhaled gas separately to prevent it from entering the nebulizer cup and contaminating the nebulized drug solution.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1

[0036] Reference Figures 1 to 9 A nebulizer for assisting the treatment of children's cough consists of a main unit 1, a nebulizer cup 2, a breathing adjustment component 3 and a breathing piece 4. The nebulizer cup 2 is a vertical columnar structure, and the internal structure is assembled with an air pipe 5, a liquid medicine pool 6, an atomizer core 7, a mist outlet pipe 8 and a nebulizer cup cover 9 in sequence from bottom to top in the vertical direction. The nebulizer cup cover 9 is connected to the top of the nebulizer cup 2 through a thread. The nebulizer cup cover 9 is provided with an air hole of adjustable size. The mist outlet pipe 8 is obliquely installed on the side wall of the nebulizer cup 2 and is connected to the nebulizer cup 2. The connection point is close to the atomizer core 7. The end of the mist outlet pipe 8 is connected to the breathing piece 4 through the breathing adjustment component 3.

[0037] The medicine liquid pool 6 is an annular groove structure at the bottom of the atomizing cup 2, which is used to store atomized medicine liquid; the lower end of the air connecting pipe 5 passes through the bottom of the atomizing cup 2 and is connected to the air outlet of the main unit 1 through the first hose 10, and the upper end extends to the top of the medicine liquid pool 6; the atomizing cup 2 is the core place for the atomization of the medicine liquid, and the upper part of the air connecting pipe 5 is located inside the atomizing cup 2. The overall structure is "narrow at the top and wide at the bottom". A nozzle 29 is integrally formed on the top, and a flow regulating valve is installed at the nozzle 29 (which can be manually adjusted by a knob or automatically controlled by the main unit). A mist baffle 30 is provided directly above the nozzle 29, and the mist baffle 30 is fixed to the atomizing core 7 by a bracket. When the compressed air provided by the main unit 1 is ejected from the nozzle 29 at high speed through the air connecting pipe 5, the airflow impacts the mist baffle 30 to generate a vortex, and at the same time forms a negative pressure around the nozzle 29.

[0038] The atomizing core 7 is divided into an upper mist-gathering section 31 and a lower siphon section 32. The siphon section 32 is cylindrical and tightly fitted onto the outer side of the conical section at the top of the air receiving pipe 5. A gap is reserved between its inner wall and the outer wall of the air receiving pipe 5 (the gap is 0.3 mm to 0.5 mm). The siphon section 32 has multiple water absorption channels 33 evenly distributed around the circumference (or the water absorption channels 33 are arranged as an annular channel). The bottom of the water absorption channel 33 is connected to the liquid medicine pool 6, and the lower end extends to the bottom of the liquid medicine pool 6. The top outlet is close to the nozzle 29. Under the action of negative pressure, the liquid medicine in the liquid medicine pool 6 is sucked into the nozzle 29 area through the water absorption channel 33, mixed with the high-speed airflow, and then impacted into the mist baffle 30 to form mist particles.

[0039] The mist gathering section 31 is a trumpet-shaped structure, the lower end of which is integrally formed with the siphon section 32, and the upper end is fixedly connected to the inside of the atomizer cup 2. An arc-shaped baffle 34 is provided on the side of the mist gathering section 31 close to the mist outlet pipe 8. The arc-shaped baffle 34 and the inner wall of the mist gathering section 31 form an arc-shaped guide channel. The mist particles gather in the mist gathering section 31 and enter the mist outlet pipe 8 through the guide channel. In addition, the arc-shaped baffle 34 can also intercept mist particles with larger diameters. These mist particles will condense into droplets on the baffle surface and flow back to the liquid medicine pool through the inner wall of the mist gathering section, thereby realizing the secondary use of the liquid medicine and reducing waste, while small mist particles (3-5μm) are not affected and diffuse out of the mist outlet pipe 8.

[0040] Reference Figures 3 to 9 The breathing adjustment component 3 is installed between the mist outlet pipe 8 and the breathing piece 4, and consists of an adjustment control part 11 and a flow guide part 12. The adjustment control part 11 and the flow guide part 12 are detachably connected by threads: the adjustment control part 11 is close to the side of the mist outlet pipe 8 and is threadedly connected to the end of the mist outlet pipe 8; the flow guide part 12 is close to the side of the breathing piece 4, and its end is fixed to the breathing piece 4 by a snap or plug.

[0041] The guide member 12 is a cylindrical structure with an integrated airflow sensor and guide blades 13. The airflow sensor is installed in the middle of the inner wall of the guide member 12 and is connected to the internal controller of the host 1 through a wire. It can monitor the breathing direction (inhalation / exhalation) and airflow in real time; 4-8 guide blades 13 are arranged and distributed in a circular array along the inner wall of the guide member 12. The blades are generally arc-shaped and have an angle of 15°-30° with the axis of the guide member 12. The spiral direction of all blades is consistent (all clockwise or counterclockwise), and the blade width gradually decreases from 2 cm on the side of the air inlet end close to the adjustment control to 1 cm on the side of the air outlet end close to the respiratory part.

[0042] When the mist enters the guide piece 12, the spiral guide blades 13 guide the airflow to flow in an axial spiral: on the one hand, it avoids the formation of turbulence due to airflow disturbance, which will cause the mist particles to collide and condense, increasing the chance of retention in the upper respiratory tract; on the other hand, the spiral acceleration effect can push the mist particles to obtain forward kinetic energy, making it easier for them to reach deep into the lungs. At the same time, the airflow sensor captures the child's breathing signals in real time, such as the increase in airflow volume during inhalation and the direction of airflow pointing to the respiratory piece, and transmits the signal to the host 1 controller.

[0043] The regulating control 11 is a cylindrical structure with the same inner diameter as the guide member 12, with a central block 15 fixed at the center thereof. A plurality of regulating blades 14 are installed between the central block 15 and the inner wall of the regulating control 11. The regulating blades 14 are fan-shaped planar blades, with the inner edges bonded and fixed to the central block 15 and the outer edges bonded and fixed to the inner wall of the regulating control 11, forming an airflow channel distributed in a ring array.

[0044] A cavity 19 is provided on the side of the regulating blade 14, and a spring 20 is installed in the cavity 19. The outer end of the spring 20 is connected to a movable plate 21. The outer side of the movable plate 21 is covered with an elastic membrane 22 (made of medical silicone). The edge of the elastic membrane 22 is sealed and bonded to the inner wall of the cavity 19 to form a fan-shaped telescopic part 16; an air inlet 17 is provided on the outer wall of the regulating control unit 11, and the air inlet 17 is connected to the air supply port of the main machine through a second hose 18, and is connected to all fan-shaped telescopic parts 16 through an internal air duct.

[0045] When the host 1 controller receives the "child inhales too fast" signal, that is, the airflow sensor detects that the inhalation flow rate is greater than the preset threshold, the air supply port is controlled to inflate the fan-shaped telescopic part 16: the elastic membrane 22 expands outward under the action of air pressure, pushing the movable plate 21 to overcome the spring 20 and move outward. At this time, the cross-sectional area of ​​the airflow channel between the regulating blades 14 is reduced, and the breathing resistance is increased. The child needs to deepen the inhalation force to obtain enough mist, and is thus forced to adjust to "slow and deep inhalation"; when the inhalation rhythm returns to normal, the host stops replenishing air (or reverses the air extraction), the spring 20 pushes the movable plate 21 to reset, the elastic membrane 22 contracts, and the breathing resistance is reduced. The dynamic adjustment response time is less than 0.5s, which can adapt to the child's breathing changes in real time and avoid discomfort caused by adjustment lag.

[0046] Reference Figures 1 to 9 The breathing part 4 is the part that children come into direct contact with, and two options are provided: a mouthpiece 26 or a breathing mask 27, both of which are made of medical-grade silicone. The mouthpiece 26 is a flat mouthpiece structure, and the rear end is connected to the guide piece 12 by a snap or plug-in method; the breathing mask 27 is an arc-shaped cover body with an inflatable sealing ring on the edge, and the rear end of the mask is also connected to the guide piece 12 by a snap.

[0047] An exhalation port 28 is provided on the side of the mouthpiece 26 or the breathing mask 27, and an exhalation valve or a one-way valve is installed on the exhalation port 28. When all the fan-shaped telescopic parts 16 are in a fully expanded state, they will block the cross-section of the adjustment control part 11. When the child's exhalation is detected, all the fan-shaped telescopic parts 16 are expanded to block the adjustment control part 11. At the same time, the exhalation valve or the one-way valve is opened to allow the exhaled gas (including carbon dioxide and secretions) to be discharged directly through the exhalation valve or the one-way valve to avoid entering the nebulizer cup and contaminating the liquid medicine.

[0048] The host 1 serves as the power and control core, and integrates an air pump, a controller and an audio player inside. The air pump provides compressed air to the air pipe 5 through the first hose 10. A display screen 24 is embedded in the front of the host 1. The display screen 24 and the audio player are both electrically connected to the internal controller.

[0049] The display screen 24 cooperates synchronously to guide breathing. When the airflow sensor detects an inhalation signal, the display screen plays an inhalation video. The video content is a "slow inhalation" action of a real person or cartoon animal. The animation duration is initially a standard inhalation time of 3-4 seconds. After several breaths, the controller adjusts the animation duration based on the average inhalation time of the user's three recorded breaths to ensure that the video breathing rhythm matches the child's actual ability. At the same time, the audio device plays the inhalation sound; when an exhalation signal is detected, the display screen plays the exhalation picture and exhalation sound. Through the combination of audio and video, the abstract breathing rhythm is converted into a signal that is easy for children to understand, reducing the difficulty of cooperation.

[0050] Example 2

[0051] The difference between this embodiment and the first embodiment is that an exhalation port 28 is provided on the side of the mouthpiece 26 or the breathing mask 27, and a one-way diaphragm (the one-way diaphragm is a plastic diaphragm) is installed in the exhalation port 28. The one-way diaphragm is adhered to the outside of the exhalation port 28, and one edge thereof is fixed. When inhaling, the one-way diaphragm closes to ensure that all the mist enters the respiratory tract; when exhaling, the one-way diaphragm is lifted outward by the airflow, and the exhaled gas is directly discharged. It has a simple structure, low cost, and can be used as a disposable product.

[0052] Example 3

[0053] The difference between this embodiment and the first embodiment is that each guide blade 13 is not fixedly installed, but is rotatably installed in the guide member 12. The rotation angle of the guide blade 13 can be fine-tuned by the host 1 according to the airflow characteristics monitored by the airflow sensor (for example, by driving a gear set to control the fine-tuning through a micro stepping motor). This design provides greater flexibility, allowing the system to dynamically optimize the spiral guide angle according to the real-time airflow conditions. When the airflow sensor detects that the mist particle flow rate is too fast, the guide blade 13 is controlled to rotate, increase the angle with the axis, and reduce the flow rate by increasing the spiral curvature to adapt to the respiratory tolerance of children; when the flow rate is too slow, the angle is reduced to increase the flow rate, ensuring that the mist particles can reach deep without irritating the respiratory tract due to excessive flow rate.

[0054] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0055] The working steps of this application are as follows:

[0056] S1: Add an appropriate amount of atomized liquid medicine to the liquid medicine pool 6 at the bottom of the atomizer cup 2, ensuring that the liquid medicine level can immerse the bottom inlet of the water absorption channel 33 of the siphon section 32, screw the atomizer cup cover 9 onto the top of the atomizer cup 2 through threads, and select a mouthpiece 26 or a breathing mask 27 according to the child's usage habits, and fix it to the end of the guide member 12 by snapping or plugging.

[0057] S2: Use the first hose 10 to connect the air outlet of the main unit 1 to the air connection pipe 5 of the atomizer cup 2, and use the second hose 18 to connect the air supply port of the main unit 1 to the air inlet 17 of the adjustment control 11. Check whether each connection part is well sealed to avoid mist leakage.

[0058] S3: Start the host 1, the internal air pump starts working, and supplies compressed air to the air connection pipe 5 through the first hose 10; at the same time, the display screen 24 of the host 1 lights up, enters the standby state, and the audio playback device is ready to provide breathing guidance prompts.

[0059] S4: Compressed air is delivered to the nozzle 29 at the top through the air connection pipe 5. The high-speed airflow is ejected from the nozzle 29 and impacts the mist baffle 30 to generate a vortex, forming a negative pressure around the nozzle 29. Under the action of the negative pressure, the liquid medicine in the liquid medicine pool 6 is sucked into the nozzle 29 area through the water absorption channel 33 of the siphon section 32, and mixed with the high-speed airflow to form mist particles.

[0060] S5: The mist particles gather in the mist gathering section 31, among which the mist particles with larger diameters are intercepted by the arc-shaped baffle 34, condensed into droplets and flow back to the liquid medicine pool 6 through the inner wall of the mist gathering section 31. The small mist particles enter the mist outlet pipe 8 through the arc-shaped guide channel and then flow into the breathing adjustment component 3.

[0061] S6: After the mist enters the guide member 12, it flows in an axial spiral under the guidance of the spiral guide blades 13; the airflow sensor in the guide member 12 monitors the breathing direction and airflow in real time, and transmits the signal to the controller of the host 1.

[0062] S7: When the child starts to inhale, the airflow sensor detects the inhalation, the host 1 controller controls the display screen 24 to play the inhalation animation, and the audio playback device emits the inhalation sound; the mist is inhaled into the child's respiratory tract through the guide member 12 and the breathing member 4.

[0063] S8: If the airflow sensor detects that the inhalation flow rate is greater than the preset threshold and the inhalation is too fast, the main unit 1 inflates the fan-shaped telescopic part 16 of the adjustment control 11 through the second hose 18, and the cross-sectional area of ​​the airflow channel between the regulating blades 14 is reduced, and the breathing resistance is increased, guiding the child to adjust to a slow and deep inhalation rhythm. When the inhalation rhythm returns to normal, the main unit 1 stops inflating, and the spring 20 pushes the movable plate 21 to return to its original position, and the breathing resistance is reduced.

[0064] S9: When the child starts to exhale, the airflow sensor detects the exhalation signal, the host 1 controller controls the display screen 24 to play the exhalation animation, and the audio player makes an exhalation sound; at the same time, all the fan-shaped telescopic parts 16 are unfolded to block the adjustment control 11, and the exhalation valve, one-way valve or one-way diaphragm of the exhalation port 28 is opened, and the exhaled gas is discharged directly to avoid entering the nebulizer cup 2 and contaminating the liquid medicine.

[0065] S10: After the treatment is completed, the main unit 1 is turned off, the hoses are disconnected, the breathing piece 4 and the nebulizer cup 2 are removed, and the relevant components are cleaned and disinfected to complete the nebulization operation.

[0066] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
