Description

Technical Field

[0001] This invention belongs to the field of medical supplies technology, specifically a nebulizer for respiratory drug delivery. Background Technology

[0002] The respiratory tract is the passageway through which airflow passes during lung respiration. The respiratory tract is divided into upper and lower parts: the nose, pharynx, and larynx are collectively called the upper respiratory tract, while the trachea, bronchi, and lungs are collectively called the lower respiratory tract, or tracheal tree. The tracheal tree has gradually become more complex with the evolution of animals.

[0003] Nebulized inhalation therapy, due to its ability to deliver medication directly to the target site in the respiratory tract, offers advantages such as rapid onset of action, high local drug concentration, and fewer systemic adverse reactions, making it an important method for treating respiratory diseases. To ensure efficacy and safety, the flow rate of the nebulized aerosol must be matched to the patient's physiological characteristics and treatment needs.

[0004] However, patients of different ages and pathological conditions have significant differences in their respiratory anatomical structure, physiological function, and tolerance, resulting in vastly different requirements for nebulization flow rates. For example, infants and young children have narrow airways and weak cough reflexes and swallowing coordination; excessively high nebulization flow rates can easily cause choking, airway spasm, or even aspiration, requiring extremely low flow rates to ensure treatment comfort. On the other hand, patients with chronic obstructive pulmonary disease (COPD) often experience dyspnea due to airway narrowing and increased expiratory resistance. If the nebulization flow rate is too low, the mist cannot effectively overcome airway resistance to reach deeper tissues, requiring an appropriate increase in flow rate to assist mist delivery and improve ventilation. In scenarios such as severe pneumonia requiring high-concentration drug pulse therapy, a high flow rate must be maintained for a short period to ensure sufficient drug deposition in the lesion area. However, existing devices lack the function of adjusting the flow rate during nebulization, thus failing to dynamically adapt the flow rate to individual patient differences, leading to significantly reduced treatment efficacy or increased safety risks.

One side of the fixed ring is magnetically set and has the opposite magnetism to that of the second magnetic ring.

[0011] Preferably, a protective ring is provided on the outer periphery of the rotating head near the other end, and the other side of the protective ring is fixedly connected to the fixed ring. A first ratchet is fixedly sleeved on the outer periphery of the rotating head near the other end, and a second ratchet is provided on one side of the first ratchet. The second ratchet is fixedly sleeved on the outer periphery of the rotating head. A second pawl and a first pawl are respectively engaged on the top of the second ratchet and the first ratchet. A second T-shaped rod and a first T-shaped rod are hinged to the top of both the first pawl and the second pawl, and the top ends of the second T-shaped rod and the first T-shaped rod movably penetrate the inner cavity of the protective ring.

[0012] Preferably, a second connecting shaft and a first connecting shaft are fixedly installed on the other side of the second pawl and the first pawl, respectively.

[0013] Preferably, the cleaning assembly includes a splined shaft that movably passes through the top of the dustproof mesh, a cleaning plate that is movably sleeved on the outer periphery of the splined shaft, a splined groove on the top of the cleaning plate, the top end of the splined shaft that movably passes through the inner cavity of the splined groove, a disassembly piece between the splined shaft and the cleaning plate, a turbine that is fixedly sleeved on the outer periphery of the splined shaft near the middle position, and a support frame that is rotatably connected to the outer periphery of the splined shaft near the bottom end, and the support frame is fixedly connected to the inner cavity sidewall of the air intake pipe.

[0014] Preferably, the disassembly component includes grooves formed on both sides of the top of the spline shaft. A connecting telescopic rod is fixedly installed on the opposite side of the inner cavity of each groove, and an arc-shaped block is fixedly installed on the opposite end of each connecting telescopic rod. A connecting spring is movably sleeved on the outer periphery of each connecting telescopic rod, and both ends of the connecting spring are fixedly connected to the inner cavity sidewall of the adjacent groove and the arc-shaped block, respectively.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention utilizes the guiding and limiting cooperation between the outer circumferential stabilizing frame of the rotating head and the irregularly shaped sliding groove of the fixed ring. The adjustable hole on the rotating head, with its diameter gradually increasing clockwise, selectively connects with the fixed through hole of the fixed ring. Combined with the status display of the indicator needle, the cross-sectional area of ​​the airflow channel can be changed with a simple rotation operation, achieving graded adjustment from small flow rate fine droplets to large flow rate coarse droplets. The small diameter hole has high resistance, low flow rate, and fine droplets, suitable for infants or patients who are sensitive to airflow and require low flow rate drug administration; the large diameter hole has low resistance, high flow rate, and coarser droplets, meeting the needs of scenarios such as severe pneumonia requiring high concentration drug pulse therapy or higher drug administration rates.

[0017] 2. This invention achieves a dynamic seal between the rotating head and the fixed ring via a supporting telescopic rod and a spring-driven rubber ring. The elastic compensation effect of the supporting spring can offset the wear and tear caused by long-term use, maintaining a tight fit between the rubber ring and the fixed ring, effectively preventing airflow leakage and ensuring that all airflow passes through the adjustment hole-through hole channel, thus guaranteeing the accuracy of flow regulation from the source. Simultaneously, the opposite-name magnetic attraction design of the second magnetic ring on the inner circumference of the rubber ring and the first magnetic ring in the first circular groove of the fixed ring generates a precise positioning force when the adjustment hole and through hole are aligned, avoiding misalignment caused by manual rotation, improving adjustment convenience. Furthermore, the magnetic attraction can dynamically adjust the rubber ring's fit during rotation, reducing friction and wear, and extending the service life of the sealing assembly.

[0018] 3. This invention utilizes the cooperation of the first ratchet, the second ratchet, the first pawl, the second pawl, and the torsion spring within the protective ring. When flow rate adjustment is required, pulling the second T-shaped rod upward causes the first pawl to deflect and unlock. After rotating to the target setting, it is released, and the torsion spring's elasticity resets the pawl and engages the ratchet. This allows clockwise rotation to increase the flow rate while preventing reverse rotation through the second ratchet and the second pawl, thus avoiding sudden changes in flow rate caused by accidental activation.

[0019] 4. The airflow through the intake pipe drives the turbine to rotate, which in turn drives the spline shaft and cleaning plate to rotate synchronously. This continuously cleans the dust and impurities on the surface of the dust filter, preventing the dust filter from becoming clogged and ensuring smooth air intake for the compressor pump. This avoids a decrease in atomization efficiency or pressure fluctuations due to insufficient air intake, ensuring long-term stable operation of the device. The cleaning plate is easily disassembled and installed using a quick-release mechanism consisting of an arc-shaped block, a connecting telescopic rod, and a connecting spring. During installation, the arc-shaped block is compressed and retracted, locking into the annular groove. During disassembly, simply press the arc-shaped block to remove it. No additional tools are required, greatly simplifying the cleaning and maintenance process of the cleaning plate, reducing the difficulty of maintenance for users, and improving the hygiene and safety of the device.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1 to 11 As shown, a nebulizer for respiratory drug delivery includes: a medical compressor nebulizer body 1, an air outlet pipe 3 installed on the top of the medical compressor nebulizer body 1 near one side, an air inlet pipe 2 installed on the top of the medical compressor nebulizer body 1 near one side, a dustproof net 7 fixedly installed in the inner cavity of the air inlet pipe 2, and a cleaning component provided on the top of the dustproof net 7; a flexible tube 4 sleeved on the outer periphery of the air outlet pipe 3 near the top, and an nebulizing cup 5 installed on the top of the flexible tube 4; a connector 6 inserted into the other side of the nebulizing cup 5; a rotating head 15 rotatably connected to the other side of the connector 6; a sealing component provided on the other side of the rotating head 15; a fixing ring 17 provided on the other side of the rotating head 15; a suction nozzle 19 fixedly installed on the other side of the through hole 20; and an adjustment component provided between the rotating head 15 and the suction nozzle 19.

[0035] The adjustment assembly includes several stabilizers 16 fixedly installed on the outer periphery of the rotating head 15. The top of the fixing ring 17 is provided with an irregularly shaped groove, and the stabilizers 16 are all slidably connected to the inner cavity of the irregularly shaped groove. Several adjustment holes are provided on the other side of the rotating head 15. A through hole 20 is provided on the other side of the fixing ring 17, and the through hole 20 corresponds to the adjacent adjustment hole. An indicator needle 18 is fixedly installed on the other side of the fixing ring 17.

[0036] Specifically, when the rotating head 15 is rotated, the stabilizing bracket 16 fixed to the rotating head 15 slides within the irregularly shaped groove. The cooperation between the stabilizing bracket 16 and the irregularly shaped groove guides and limits the rotation of the rotating head 15, preventing it from shifting or wobbling during rotation. Simultaneously, as the rotating head 15 rotates, the relative position between the adjustment hole on its other side and the through hole 20 on the fixing ring 17 changes, thereby adjusting the nebulized airflow at the nozzle 19. The indicator needle 18 fixedly installed on the other side of the fixing ring 17 clearly indicates the current correspondence between the adjustment hole and the through hole 20, allowing users to intuitively understand the degree of nebulized airflow adjustment to meet the personalized needs of different patients for nebulized drug delivery flow.

[0037] It should be noted that medical compressor nebulizers mainly consist of a main unit, a compressor pump, a nebulizer cup 5, a connecting tube, a nozzle, and, in some models, an air filter and a power cord. The main unit contains a control circuit and an air pressure regulation module. The compressor pump generates high-pressure airflow by driving a piston or diaphragm through a motor. This high-speed airflow is delivered to the nebulizer cup 5 through the tube. The Venturi effect or airflow shear force is used to break the liquid medication in the cup into tiny droplets. The bottom or side wall of the nebulizer cup 5 has a drug inlet and a mist outlet. The connecting tube guides the atomized aerosol to the patient's end. The mask or mouthpiece ensures that the medication accurately enters the respiratory tract. The air filter purifies the air entering the compressor pump to protect the internal components. The power cord powers the entire machine. Some high-end models also integrate timer, speed adjustment, or liquid medication monitoring functions. All components work together to achieve stable and efficient nebulized drug delivery.

[0038] The diameter of several adjustment holes gradually increases in a clockwise direction.

[0039] The size of the through-hole 20 is fixed. The maximum diameter of the adjustment hole on the rotating head 15 matches that of the through-hole 20. The through-hole 20 connects with adjustment holes of different diameters, thereby changing the cross-sectional area of ​​the airflow channel. Adjustment holes with smaller diameters create greater resistance to the airflow, reducing the flow rate of the nebulized air and producing relatively fine droplets, suitable for patients sensitive to airflow or requiring low-flow-rate drug delivery. Conversely, adjustment holes with larger diameters offer less resistance, increasing the airflow rate and producing relatively larger droplets, which can meet the needs of scenarios requiring higher drug delivery rates. This design achieves graded adjustment of the nebulization flow rate through a simple mechanical structure, is convenient and reliable to operate, and can adapt to diverse clinical needs without the need for a complex electronic control system.

[0040] The sealing assembly includes several second circular grooves 24 formed on the rotating head 15. The second circular grooves 24 are respectively connected to the outer periphery of the adjacent adjustment holes. The inner cavity of each second circular groove 24 is fixedly installed with a support telescopic rod 25. The ends of the support telescopic rods 25 are all fixedly installed with rubber rings 27. The outer periphery of each support telescopic rod 25 is movably sleeved with a support spring 26, and the two ends of the support spring 26 are fixedly connected to the second circular groove 24 and the rubber ring 27 respectively.

[0041] The support telescopic rod 25 and the support spring 26 ensure that the rubber ring 27 is in tight contact with the fixed ring 17, effectively preventing leakage of the atomized airflow at the gap between the rotating head 15 and the fixed ring 17. This ensures that the airflow can pass entirely through the channel formed by the adjusting hole and the through hole 20, thereby guaranteeing the accuracy and stability of the atomization flow rate adjustment. When the rotating head 15 is rotated to switch between adjusting holes of different diameters, the rubber ring 27 remains in close contact with the surface of the fixed ring 17 under the continuous elastic force of the support spring 26. Even if the components are slightly worn due to long-term use, the elastic compensation effect of the support spring 26 can maintain a good sealing effect, further improving the durability and reliability of the device.

[0042] The inner circumference of the rubber ring 27 is fixedly installed with a second magnetic ring 28. A number of first circular grooves 23 are opened on one side of the fixing ring 17. The first circular grooves 23 correspond to the adjacent second circular grooves 24 respectively. The inner cavity of the first circular grooves 23 is fixedly installed with a first magnetic ring 22. One side of the fixing ring 17 is magnetically set and has the opposite magnetism to the second magnetic ring 28.

[0043] Specifically, when the rotating head 15 rotates until a certain adjustment hole aligns with the through hole 20 on the fixed ring 17, the second magnetic ring 28 in the second circular groove 24 on the outer periphery of the adjustment hole will attract the first magnetic ring 22 in the corresponding first circular groove 23 on the fixed ring 17. This magnetic attraction will play a precise positioning role in the rotation of the rotating head 15, ensuring that the adjustment hole and the through hole 20 can be aligned quickly and accurately, avoiding the problem of hole misalignment caused by deviation during manual rotation, and significantly improving the convenience and accuracy of atomization flow adjustment operation. At the same time, when the rubber ring 27 changes position during the rotation of the rotating head 15, one side of the fixed ring 17 is magnetically set. During the rotation of the rubber ring 27, the rubber ring 27 can be separated from the fixed ring 17, avoiding wear of the rubber ring 27 during rotation, which would affect the subsequent airtightness.

[0044] A protective ring 21 is provided on the outer periphery of the rotating head 15 near one end, and the other side of the protective ring 21 is fixedly connected to the fixed ring 17. A first ratchet 29 is fixedly sleeved on the outer periphery of the rotating head 15 near one end. A second ratchet 36 is provided on one side of the first ratchet 29, and the second ratchet 36 is fixedly sleeved on the outer periphery of the rotating head 15. The tops of the second ratchet 36 and the first ratchet 29 are respectively engaged with a second pawl 30 and a first pawl 33. The tops of the first pawl 33 and the second pawl 30 are both hinged with a second T-shaped rod 32 and a first T-shaped rod 31. The top ends of the second T-shaped rod 32 and the first T-shaped rod 31 both movably penetrate the inner cavity of the protective ring 21. The second connecting shaft 37 and the first connecting shaft 34 are fixedly installed on the other side of the second pawl 30 and the first pawl 33, respectively. The second torsion spring 38 and the first torsion spring 35 are movably sleeved on the outer periphery of the second connecting shaft 37 and the first connecting shaft 34, respectively. One end of the second torsion spring 38 and the first torsion spring 35 are fixedly connected to the second connecting shaft 37 and the first connecting shaft 34, respectively, and the other end of the second torsion spring 38 and the first torsion spring 35 are fixedly connected to the fixing ring 17.

[0045] Specifically, when it is necessary to rotate the rotating head 15 clockwise to increase the atomization flow rate, the second T-shaped rod 32 is pulled upwards, causing the center of the first connecting shaft 34 of the first pawl 33, which is hinged on the second T-shaped rod 32, to deflect away from the adjacent teeth of the first ratchet 29. Then the rotating head 15 can be rotated, which can change the atomization flow rate clockwise. By setting the second ratchet 36 and the second pawl 30, the rotating head 15 can be prevented from rotating in the opposite direction, thus improving the stability after adjustment.

[0046] The cleaning assembly includes a splined shaft 8 that moves through the top of the dustproof mesh 7. A cleaning plate 39 is movably fitted around the outer periphery of the splined shaft 8. A spline groove is opened at the top of the cleaning plate 39. The top of the splined shaft 8 moves through the inner cavity of the spline groove. A disassembly piece is provided between the splined shaft 8 and the cleaning plate 39. A turbine 13 is fixedly fitted around the outer periphery of the splined shaft 8 near the middle position. A support frame 14 is rotatably connected around the outer periphery of the splined shaft 8 near the bottom end. The support frame 14 is fixedly connected to the inner cavity side wall of the air intake pipe 2.

[0047] Specifically, when the atomizing device is working, airflow will flow in the air intake pipe 2. When the airflow passes through the turbine 13, it will drive the turbine 13 to rotate around the axis of the spline shaft 8. Since the turbine 13 is fixedly connected to the spline shaft 8, the rotation of the turbine 13 will drive the spline shaft 8 to rotate synchronously. The spline shaft 8 engages with the spline groove on the top of the cleaning plate 39 through the spline, thereby driving the cleaning plate 39 to rotate together, thereby sweeping away the dust, impurities and other foreign objects attached to the surface of the dust screen 7, effectively preventing the dust screen 7 from being blocked, ensuring unobstructed air intake in the air intake pipe 2, and ensuring that the atomizing device can work stably and efficiently. When it is necessary to clean the cleaning plate 39, the cleaning plate 39 can be easily removed from the spline shaft 8 by operating the disassembly parts. The operation is simple and convenient, and easy to maintain. The support frame 14 provides stable support for the spline shaft 8, preventing the spline shaft 8 from shaking or shifting during high-speed rotation, and ensuring the stability and reliability of the cleaning component operation.

[0048] The disassembly component includes grooves 9 on both sides of the top of the spline shaft 8. A connecting telescopic rod 10 is fixedly installed on the opposite side of the inner cavity of the groove 9. An arc-shaped block 12 is fixedly installed on the opposite end of the connecting telescopic rod 10. A connecting spring 11 is movably sleeved on the outer periphery of the connecting telescopic rod 10, and both ends of the connecting spring 11 are fixedly connected to the inner cavity sidewall of the adjacent groove 9 and the arc-shaped block 12, respectively.

[0049] Specifically, when the cleaning plate 39 needs to be installed, align the spline groove on the top of the cleaning plate 39 with the lower end of the spline shaft 8 and push it upwards. At this time, the inclined surface of the arc-shaped block 12 will be squeezed by the inner wall of the spline groove of the cleaning plate 39, causing the arc-shaped block 12 to retract into the groove 9. The connecting telescopic rod 10 is compressed, and the connecting spring 11 is also compressed and stores force. As the cleaning plate 39 continues to be pushed upwards, when the top of the cleaning plate 39 contacts the stepped surface on the spline shaft 8, the arc-shaped block 12 just moves to the position of the annular slot above the spline groove of the cleaning plate 39. At this time, the connecting spring 11 releases its elastic force, pushing... The telescopic rod 10 extends, which in turn causes the arc-shaped block 12 to pop out of the groove 9 and lock into the annular slot, thus firmly installing the cleaning plate 39 on the spline shaft 8 and preventing it from falling off during rotation. When it is necessary to remove the cleaning plate 39 for cleaning, simply press the arc-shaped blocks 12 on both sides with your fingers at the same time, so that the arc-shaped blocks 12 overcome the elastic force of the connecting spring 11 and retract into the groove 9, thus disengaging from the restriction of the annular slot. At this time, the cleaning plate 39 can be easily pulled off the spline shaft 8. The entire disassembly process is quick and convenient, without the need for additional tools, which greatly improves the convenience of maintenance.

[0050] During operation, the compressor pump inside the medical compressor nebulizer body 1 generates high-pressure airflow by driving the piston or diaphragm through a motor. This airflow enters the device through the air inlet pipe 2. As the airflow passes through the turbine 13, it drives the turbine 13 to rotate around the splined shaft 8. The turbine 13 drives the splined shaft 8 to rotate synchronously. The splined shaft 8 engages with the spline groove of the cleaning plate 39 via a spline joint (the cleaning plate 39 is easily disassembled and assembled using a disassembly mechanism consisting of an arc-shaped block 12, a connecting telescopic rod 10, and a connecting spring 11. During installation, the arc-shaped block 12 is compressed and retracted, locking into an annular groove; during disassembly, pressing the arc-shaped block 12 removes it). This drives the cleaning plate 39 to rotate, continuously cleaning dust and impurities from the surface of the dustproof mesh 7 inside the air inlet pipe 2, preventing dust from entering the mesh. 7. Blocking ensures unobstructed airflow; another high-pressure airflow is delivered to the atomizing cup 5 via the outlet pipe 3 and hose 4. Utilizing the Venturi effect or airflow shear force, the liquid medicine in the cup is broken into tiny droplets. The atomized aerosol enters the connector 6 through the outlet on the other side of the atomizing cup 5, and then enters the rotating head 15. The stabilizing frame 16 on the outer periphery of the rotating head 15 slides along the irregular groove of the fixing ring 17, guiding and limiting the rotation of the rotating head 15 to prevent deviation and wobbling. Multiple adjustment holes with progressively larger diameters on the other side of the rotating head 15 selectively communicate with the through holes 20 fixed on the fixing ring 17. Together with the indicator needle 18 on the fixing ring 17, the gear position is visually displayed by changing the airflow. The cross-sectional area of ​​the flow channel enables graded adjustment of the atomization flow rate—small-diameter adjustment orifices have high resistance, low flow rate, and fine droplets, suitable for patients sensitive to airflow or requiring low-flow administration; large-diameter adjustment orifices have low resistance, high flow rate, and coarser droplets, meeting the needs of scenarios requiring higher administration speeds. Simultaneously, the rotating head 15 and the fixed ring 17 are sealed against leakage by a rubber ring 27 driven by a support telescopic rod 25 and a support spring 26. The second magnetic ring 28 on the inner circumference of the rubber ring 27 and the first magnetic ring 22 (with opposite magnetic properties) in the first circular groove 23 of the fixed ring 17 attract each other when the adjustment orifice and the through hole 20 are aligned, achieving precise positioning and preventing misalignment. Furthermore, the magnetic attraction force can be dynamically adjusted between the rubber ring 27 and the fixed ring 17 during rotation. The rotating head 15 is fitted to a certain degree to reduce wear. The protective ring 21 on the outer periphery of the rotating head 15 is provided with a first ratchet 29, a second ratchet 36 and a first pawl 33 and a second pawl 30 respectively engaged between their teeth. The first T-shaped rod 31 and the second T-shaped rod 32, which are hinged to the top of the first pawl 33 and the second pawl 30, pass through the protective ring 21. The first torsion spring 35 and the second torsion spring 38 on the outer periphery of the connecting shaft keep the pawl engaged with the ratchet in normal state. When it is necessary to rotate the rotating head 15 clockwise to increase the flow rate, the second T-shaped rod 32 is pulled upward to deflect the first pawl 33 away from the teeth of the first ratchet 29. After rotating to the target gear, it is released. The spring force of the torsion spring makes the pawl reset and lock to prevent reverse rotation and ensure stability after adjustment.Finally, the aerosol, with its flow rate and droplet size adjusted to a specific value, enters the mouthpiece 19 through the through-hole 20 of the fixing ring 17. After inhalation, the medication is carried by the airflow to the target area of ​​the respiratory tract. The various components work together to achieve stable nebulization, self-cleaning air intake, precise flow rate adjustment, leak-proof sealing, magnetic positioning, anti-reverse locking, and convenient maintenance, adapting to the individualized treatment needs of different patients.
