[0002] In the existing field of pulmonary airway clearance therapy, traditional airway clearance techniques such as back percussion and postural drainage mainly rely on manual operation by nursing staff, which is inefficient and the effect is difficult to guarantee uniformity.

[0003] Traditional high-frequency chest wall oscillation devices use a single external mechanical vibration, which has limited effect on loosening secretions inside the airway, making it difficult to effectively clear deep airways and resulting in low efficiency.

[0004] To address the aforementioned issues, this patent proposes a novel lung airway clearance therapy device that can directly generate highly efficient dual vibrations inside the respiratory tract, is compact and durable, easy to clean and disinfect, and is hygienic and safe to use. Utility Model Content

[0005] The main purpose of this invention is to propose a lung airway clearance therapy device, which aims to solve the problem that traditional high-frequency chest wall oscillation devices, which use a single external mechanical vibration, are difficult to achieve effective clearance of deep airways and have low efficiency.

[0006] To address the aforementioned problems, this utility model proposes a pulmonary airway clearance therapy device, comprising a vibrating air cylinder, a drive chamber connected to the lower end of the vibrating air cylinder, multiple normally open air holes on the outer side of the front end of the vibrating air cylinder, a flow-changing air hole at the center of the front end of the vibrating air cylinder, and the flow-changing air hole being located in the middle of the multiple normally open air holes, a breathing nozzle connected to the rear end of the vibrating air cylinder, a vibration sealing component disposed inside the front end of the vibrating air cylinder, and the vibration component causing the air inside the vibrating air cylinder to generate pulse vibration and mechanical vibration, and a drive component disposed inside the drive chamber, and the drive component driving the vibration component.

[0007] Preferably, the drive assembly includes a drive shaft, a support frame, and a pusher shaft. The drive shaft is rotatably connected to the central axis inside the drive chamber. Multiple support frames are connected to the outside of the drive shaft, and pusher shafts are rotatably connected to the inner outer ends of the multiple support frames.

[0008] Preferably, the vibration assembly includes a sealing head, and a limiting sliding chamber is connected to the front side of the upper inner wall of the vibration cylinder, with a connecting groove provided at the lower end and rear end of the limiting sliding chamber.

[0009] Preferably, a connecting slider is slidably connected inside the limiting sliding chamber, and a front push rod is connected to the lower end of the connecting slider. The front push rod is located on the central axis of the vibrating air cylinder and is slidably connected inside the lower end of the connecting groove.

[0010] Preferably, a vibrating air cylinder is sleeved on the front side of the front push rod, and a limiting slide is connected to the inner wall of the vibrating air cylinder. A sealing head is connected to the front end of the front push rod, and the sealing head is located directly behind the flow-changing air hole.

[0011] Preferably, a rear push rod is connected to the upper side of the rear end of the connecting slider, and the rear push rod is slidably connected inside the rear end of the connecting groove and fits against the inner wall of the upper end of the vibrating air cylinder.

[0012] Preferably, the rear end of the rear push rod is rotatably connected to a linkage roller, and the front end of the connecting slider is provided with a return spring, which is elastically connected to the limit sliding chamber through the return spring.

[0013] Beneficial effects:

[0014] 1. This utility model uses a vibration component to periodically block and open the flow-changing vent, causing a sudden change in the cross-sectional area of ​​the airflow channel, thereby generating pressure pulse vibration inside the airflow; at the same time, its own mechanical movement directly transmits mechanical vibration to the gas; through the dual effect of the combination of air pressure pulse and mechanical vibration, high-frequency oscillation is applied to the secretions in the patient's lung airway, promoting the loosening and discharge of secretions, and improving the efficacy of airway clearance.

[0015] 2. The drive motor of this utility model transforms a single rotational motion into a continuous and intermittent pushing force on the vibration component through a drive assembly consisting of a drive shaft, a support frame, and a pushing shaft. This ensures that the vibration component can obtain a stable and continuous power input, thereby generating regular vibration with controllable frequency, providing core power guarantee for the treatment process.

[0016] 3. The vibration assembly of this utility model adopts a coordinated design of a limiting sliding chamber, a connecting slider, a return spring, and a front push rod. Under the alternating action of the pushing force of the drive assembly and the restoring force of the spring, the sealing head at the front end of the front push rod is driven to reciprocate precisely, realizing the rapid and accurate sealing and opening of the variable flow air hole. The limiting slide on the front push rod ensures the stability of its movement trajectory, effectively prevents deviation, and ensures the accuracy and reliability of the sealing action.

[0017] 4. The pushing shaft in the drive assembly and the linkage roller in the vibration assembly of this utility model are both connected by rotation. When the two come into contact and transmit thrust, they can adjust the contact position by rotating themselves, converting sliding friction into rolling friction, reducing wear between parts, improving service life, and enhancing the durability of the equipment.

[0018] 5. The breathing nozzle of this utility model is connected to the main body through a snap-fit ​​connector, which makes it easy to replace or clean according to different patients. The misaligned baffle set inside the breathing nozzle can effectively intercept secretions carried in the patient's exhaled air and prevent secretions from entering the instrument body. Combined with the detachable sealing plate on the side of the drive chamber, it achieves effective protection of the instrument's interior and simplifies cleaning and disinfection, ensuring hygiene and safety for cross-use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To achieve the above-mentioned utility model objectives, such as Figures 1-4 As shown, this utility model provides a lung airway clearance therapy device, including a vibrating air cylinder 1. A drive chamber 2 is connected to the lower end of the vibrating air cylinder 1. Multiple normally open air holes 3 are opened on the outer side of the front end of the vibrating air cylinder 1. A flow-changing air hole 4 is opened at the center of the front end of the vibrating air cylinder 1, and the flow-changing air hole 4 is located in the middle of the multiple normally open air holes 3. A breathing nozzle 5 is connected to the rear end of the vibrating air cylinder 1. Inclined misaligned baffles 18 are connected to the inner walls of both the upper and lower ends of the breathing nozzle 5. A controller 19 is provided at the right end of the drive chamber 2. A sealing plate 20 is snapped into the left end of the drive chamber 2. A drive motor 21 is provided inside the right end of the controller 19. A vibration sealing component is provided inside the front end of the vibrating air cylinder 1, and the air inside the vibrating air cylinder 1 generates pulse vibration and mechanical vibration through the vibration component. A drive component is provided inside the drive chamber 2, and the vibration component is driven by the drive component. The component is connected to the drive motor 21 via the motor shaft. During the process of clearing the patient's lung airway, the patient holds the rear end of the breathing nozzle 5 in their mouth and takes a deep breath through the breathing nozzle 5. The patient's breathed air is guided through the normally open air hole 3 and the variable flow air hole 4 inside the vibrating air cylinder 1, and is introduced and exported through the normally open air hole 3 and the variable flow air hole 4. At this time, the left end of the controller 19 is equipped with a display screen and a speed control knob. The controller 19 starts the drive motor 21 through the speed control knob, controls the speed of the drive motor 21, and displays the speed on the display screen. The drive motor 21 drives the drive component to run, and then drives the vibration component through the drive component, so that the patient's breathed air generates pulse vibration and mechanical vibration. The vibrating breathed air causes high-frequency oscillation of secretions inside the lung airway, which accelerates the loosening and discharge of lung airway secretions and promotes lung airway patency.

[0028] The vibration component can continuously block and open the variable flow vent 4. When the variable flow vent 4 is blocked, the inlet and outlet openings of the vibrating air cylinder 1 suddenly become smaller, resulting in a sudden decrease in the flow rate of the inlet and outlet gas and an increase in the internal air pressure. Conversely, when the variable flow vent 4 is opened, the inlet and outlet openings of the vibrating air cylinder 1 suddenly become larger, resulting in a sudden increase in the flow rate of the inlet and outlet gas and a decrease in the internal air pressure. This causes the breathing gas pressure inside the vibrating air cylinder 1 to change continuously, thereby generating pulse vibration. At the same time, the vibration component generates mechanical vibration under the drive component, which in turn causes the breathing gas inside the vibrating air cylinder 1 to generate mechanical vibration.

[0029] In addition, the breathing nozzle 5 is connected to a snap-fit ​​connector at the rear end, and can be connected and disconnected from the vibrating air cylinder 1 through the snap-fit ​​connector, allowing the breathing nozzle 5 to be replaced according to the use of different patients. The breathing nozzle 5 can also intercept and collect secretions brought out by the patient's breathing through two internally set staggered baffles 18, preventing secretions from entering the vibrating air cylinder 1 and the drive chamber 2. At the same time, the drive chamber 2 can be cleaned and disinfected by removing the sealing snap-fit ​​plate 20, making the use of the treatment device more hygienic.

[0030] Preferably, the drive assembly includes a drive shaft 6, a support frame 7, and a pusher shaft 8. The drive shaft 6 is rotatably connected to the central axis inside the drive chamber 2. Multiple support frames 7 are connected to the outside of the drive shaft 6. The pusher shaft 8 is rotatably connected to the inner side of the outer end of each of the multiple support frames 7. During the operation of the drive assembly, the drive motor 21 is connected to the drive shaft 6 through the motor shaft, and drives the multiple support frames 7 to rotate inside the drive chamber 2 through the drive shaft 6, while simultaneously driving the multiple pusher shafts 8 to rotate outside the drive chamber 2.

[0031] Preferably, the vibration assembly includes a sealing head 14. A limiting sliding chamber 9 is connected to the front side of the upper inner wall of the vibrating air cylinder 1. A connecting groove 10 is provided at the lower and rear ends of the limiting sliding chamber 9. A connecting slider 11 is slidably connected inside the limiting sliding chamber 9. A front push rod 12 is connected to the lower end of the connecting slider 11, and the front push rod 12 is located on the central axis of the vibrating air cylinder 1 and slidably connected inside the lower end of the connecting groove 10. The vibrating air cylinder 1 is sleeved on the front side of the front push rod 12, and a limiting slide 13 is connected to the inner wall of the vibrating air cylinder 1. The sealing head 14 is connected to the front end of the front push rod 12, and the sealing head 14 is located directly behind the flow-changing air hole 4. A rear push rod 15 is connected to the upper side of the rear end of the connecting slider 11, and the rear push rod 15 is slidably connected inside the rear end of the connecting groove 10 and fits against the upper inner wall of the vibrating air cylinder 1. A linkage roller 16 is rotatably connected to the rear side of the lower end of the rear push rod 15. A return spring 17 is provided at the front end of the connecting slider 11. The device is elastically connected to the limiting sliding chamber 9 via a return spring 17. During the driving of the vibration assembly, multiple pushing shafts 8 rotate and sequentially contact the linkage roller 16, pushing the linkage roller 16 forward. This causes the linkage roller 16 to drive the connecting slider 11 to slide backward inside the limiting sliding chamber 9 via the rear push rod 15. In the gap between the contact between two adjacent pushing shafts 8 and the linkage roller 16, the connecting slider 11 will slide backward inside the limiting sliding chamber 9 under the action of the return spring 17. This allows the connecting slider 11 to drive the sealing head 14 to engage and disengage from the flow-changing air hole 4 via the front push rod 12, thereby sealing and opening the flow-changing air hole 4 and causing the gas inside the vibrating air cylinder 1 to generate pulse vibration. At the same time, the back-and-forth sliding of the connecting slider 11 inside the limiting sliding chamber 9 generates mechanical vibration, which in turn causes the gas inside the vibrating air cylinder 1 to generate mechanical vibration.

[0032] Among them, the front push rod 12 can be limited by the limiting slide 13 to ensure that the sealing head 14 can be accurately inserted into the flow converter vent 4 for sealing.

[0033] Furthermore, when the push shaft 8 contacts and pushes the linkage roller 16, since the push shaft 8 is rotatably connected to the inner side of the outer end of the support frame 7 and the linkage roller 16 is rotatably connected to the rear side of the lower end of the rear push rod 15, the push shaft 8 and the linkage roller 16 can adjust their positions by rotation during the contact and pushing process, thereby reducing the wear between the push shaft 8 and the linkage roller 16 and improving durability.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
