Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a nebulizer for assisting postoperative care in thoracic surgery. Background Technology

[0002] Open-chest surgery is highly invasive and time-consuming, leading to increased respiratory secretions post-operatively. It also interferes with lung function, reducing ventilation and weakening respiratory muscles, resulting in difficulty coughing up sputum and decreased ability to expel sputum. Nebulized inhalation, as a treatment method, is widely used clinically to treat various respiratory diseases. It is an important means of thinning sputum, reducing inflammation, relieving bronchospasm, and improving ventilation.

[0003] Existing technology discloses some invention patents for atomizers. Chinese Patent Application No. 202011165971.3 discloses an essential oil atomizer, comprising the following structure: a chassis, a housing, an atomization chamber, an air pump, an air tube, a gas nozzle, an oil nozzle, and a filter atomization mechanism. The housing is configured to connect to an oil container, and the housing has a discharge opening; the gas nozzle and the oil nozzle are configured to fluidly communicate with a gas source and to fluidly communicate with oil in the oil container, so as to atomize the oil using gas from the gas source; the atomizer also includes a cover movable between a first position where the discharge opening is not sealed and a second position where the discharge opening is sealed by the cover.

[0004] Nebulizers break down medications into small droplets or particles, or aerosols, with diameters of a few micrometers. As the patient breathes, the medication directly enters the respiratory tract and lungs. Because aerosol particles aggregate upon contact, forming large droplets or aggregates, this process is extremely rapid. When the inhaled aerosol particles are large, these larger particles entering the airway may cause spasms of the bronchial smooth muscle, leading to wheezing, primarily manifested as difficulty breathing. Therefore, this invention proposes a nebulizer device for assisting postoperative care in thoracic surgery to address these problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a nebulization device for assisting postoperative care in thoracic surgery.

[0011] Preferably, the vibration assembly includes a circular groove and a circular rod. The circular groove is located at one end of the rotating rod outside the cavity. Pins are symmetrically fixed on the inner wall of the circular groove. The circular rod is fixedly connected to the side of the screen facing the cavity.

The outer ring of the circular rod is provided with a reciprocating thread, and both pins are matched with the reciprocating thread.

[0012] Preferably, the second atomizing mechanism includes a conical plate fixed to the inner wall of the discharge pipe. A through hole is provided at the right end of the conical plate.

A second ring is fixed to the right end of the first ring. The second ring is slidably connected to the round rod. A plurality of air outlet pipes are fixedly connected to the outer circumferential array of the first ring. The first ring is sleeved on the outer ring of the round rod. The inner diameter of the first ring is slightly larger than the outer diameter of the round rod.

[0013] Preferably, the plurality of air outlet pipes are arranged at an angle.

The reflux trough is located between the screen and the conical plate, and the end of the reflux trough away from the discharge pipe is fixedly connected to the outer ring of the bottle body.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The vibrating mechanism drives the screen to vibrate reciprocally. This vibration shakes off the droplets adhering to the screen. During the fall, some of the droplets pass through the second atomizing mechanism, where they are atomized again into smaller droplets by the airflow and pass through the screen holes. The remaining droplets flow along the discharge pipe and are then returned to the inside of the bottle through the return mechanism for atomization. This process effectively breaks up the aggregated droplets generated during atomization, preventing patients from inhaling excessively large droplets and reducing adverse symptoms during nebulization therapy.

[0020] 2. By tilting the air outlet pipe, the high-speed airflow is sprayed at an angle onto the inner wall of the discharge pipe. The airflow then flows along the inner wall of the discharge pipe to form a vortex. The vortex causes the sprayed droplets to rotate, thereby reducing the collision between droplets and the inner wall of the discharge pipe. At the same time, the rotating flow of droplets reduces the collision between droplets, thereby reducing droplet aggregation and thus reducing the formation of large droplets, which helps to improve the effect of nebulization therapy.

[0021] 3. With the included return trough, when large droplets shaken off the screen cannot move with the airflow, they will flow along the inner wall of the discharge pipe into the return trough under gravity, and then enter the medication solution. This helps prevent excessive medication accumulation in the discharge pipe from affecting the movement trajectory of small droplets with the airflow, thus facilitating the reuse of the medication solution, reducing waste, and ensuring sufficient medication content in the aerosol, thereby enabling patients to receive effective nebulization therapy.

[0034] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0035] like Figures 1 to 11 The nebulizer shown is for assisting postoperative care in thoracic surgery. It includes a bottle body 1, a top cover 2 slidably connected to the top of the bottle body 1, a handle 3 fixed to the upper end of the outer ring of the bottle body 1, a discharge pipe 4 fixedly connected to the upper end of the outer ring of the bottle body 1, a connecting pipe 5 fixedly connected to the bottom of the bottle body 1, and an air inlet pipe 6 slidably inserted into the bottom of the connecting pipe 5.

[0036] A first atomizing mechanism is connected to the bottom side wall inside the bottle body 1. The first atomizing mechanism is used to atomize the liquid medicine inside the bottle body 1. A screen 7 is slidably connected inside the discharge pipe 4. A vibration mechanism is installed inside the bottle body 1. The vibration mechanism is located above the first atomizing mechanism. The vibration mechanism is used to drive the screen 7 to vibrate. A second atomizing mechanism is installed inside the discharge pipe 4. The second atomizing mechanism is located between the bottle body 1 and the screen 7. The second atomizing mechanism is used to atomize the large droplets that are aggregated during the movement.

[0037] A reflux mechanism is installed between the discharge pipe 4 and the bottle body 1. This mechanism guides large droplets filtered out by the screen 7 back into the interior of the bottle body 1. During operation, the nebulizer breaks down the medication into small droplets or particles with a diameter of a few micrometers, i.e., aerosols. As the patient breathes, the medication directly enters the respiratory tract and lungs. Due to the aerosol particles colliding, they aggregate to form large droplets or aggregates. This process proceeds extremely rapidly. When the aerosol particles inhaled by the patient are large, these larger particles may cause bronchospasm after entering the airway. Muscle spasms, leading to wheezing, are mainly manifested as difficulty breathing. This embodiment of the invention can solve the above problems. The specific implementation method is as follows: First, the user opens the top cover 2, adds the medicine into the bottle 1, then closes the top cover 2, connects the air inlet pipe 6 to the air outlet of the compressor, and then starts the compressor. The compressor compresses air and passes it through the air inlet pipe 6 into the first atomizing mechanism. In the first atomizing mechanism, the medicine is atomized into small droplets and moves upward under the drive of the airflow. The atomized droplets enter the discharge pipe 4 and pass through the first atomizing mechanism. The secondary atomizing mechanism can re-atomize large droplets that aggregate due to collisions during the movement of the atomized droplets, turning them into smaller droplets. This helps to reduce discomfort experienced by patients during nebulization therapy. The atomized droplets, driven by the airflow, impact the screen 7 inside the discharge pipe 4. Small droplets can pass directly through the screen holes, while large droplets, upon impacting the side wall of the screen 7, are partially broken into smaller droplets that can pass through the screen holes, and partially condense into water droplets on the screen 7. A vibration mechanism can then drive the screen 7 to vibrate... The reciprocating vibration of the screen 7 shakes off the droplets adhering to it. During the fall, some of the droplets pass through the second atomization mechanism and are atomized again into smaller droplets by the airflow, passing through the screen holes. The remaining droplets flow along the discharge pipe 4 and are returned to the inside of the bottle 1 through the return mechanism for atomization again. This helps to fully break up the aggregated droplets generated during atomization, thus preventing patients from inhaling excessively large droplets and reducing the occurrence of adverse symptoms during nebulization therapy.

[0038] In one embodiment of the present invention, the first atomizing mechanism includes a mounting block 8, which is fixed to the bottom side wall inside the bottle body 1. The mounting block 8 is conical, with a conical hole 9 at its bottom, which communicates with the connecting pipe 5. A first circular hole 10 is provided through the top of the mounting block 8, which communicates with the conical hole 9. A frustum-shaped sleeve 12 is fixedly fitted around the outside of the mounting block 8. Two water inlet grooves 13 are symmetrically provided inside the frustum-shaped sleeve 12, with the tops of both water inlet grooves 13 penetrating the top of the frustum-shaped sleeve 12. A connecting groove 11 is provided between the two water inlet grooves 13, with the bottoms of both water inlet grooves 13 communicating with the bottom of the bottle body 1. The two ends of the connecting groove 11 are connected to the two water inlet grooves 13, and the bottom of the connecting groove 11 is connected to the first circular hole 10. During operation, when the operator starts the compressor, compressed air is sent from the compressor outlet into the air inlet pipe 6, and then compressed air... Air passes through the connecting pipe 5 and enters the conical hole 9. Since the bottom diameter of the conical hole 9 is larger than the top diameter, the compressed air moves from the bottom to the top in the conical hole 9, and the flow rate of the compressed air increases, becoming a high-speed airflow. The high-speed airflow passes through the first circular hole 10 and enters the interior of the connecting groove 11, and then sprays out from the top of the connecting groove 11. When the high-speed airflow passes through the connecting groove 11, it generates low pressure, so that the air pressure at the top of the connecting groove 11 is lower than the air pressure at the bottom of the connecting groove 11. As a result, the liquid medicine inside the bottle 1 moves upward along the connecting groove 11. When the liquid medicine reaches the top of the connecting groove 11, under the impact of the high-speed airflow, the liquid medicine is impacted into tiny droplets and moves with the airflow inside the bottle 1. Finally, it is sprayed out from the discharge pipe 4 with the airflow and inhaled by the patient. By dispersing the liquid medicine into tiny droplets, it is easier for the liquid medicine to enter the respiratory tract and lungs through inhalation, thus facilitating painless, rapid and effective treatment for the patient.

[0039] In one embodiment of the present invention, the vibration mechanism includes three connecting rods 14, which are circumferentially arrayed and fixed to the inner sidewall of the bottle body 1. A cylinder 15 is fixed to the end of each connecting rod 14 away from the inner wall of the bottle body 1. A cavity 16 is formed inside the cylinder 15. A vertical rod 17 is rotatably connected to the top sidewall of the cavity 16. The bottom end of the vertical rod 17 passes through the bottom sidewall of the cylinder 15 and the top of the frustum-shaped sleeve 12, extending into the conical hole 9. An impeller 18 is fixed to the lower end of the outer ring of the vertical rod 17, and a first bevel gear 19 is fixed to the top of the vertical rod 17. A rotating rod 20 is rotatably mounted on the sidewall of the cylinder 15. A second bevel gear 22 is fixed to one end of the rotating rod 20, meshing with the first bevel gear 19. The other end of the rotating rod 20 passes through the sidewall of the cylinder 15 and extends outwards. A vibration device is installed between the rotating rod 20 and the screen 7. The vibrating component drives the screen 7 to reciprocate. During operation, as the airflow moves inside the conical hole 9, it drives the impeller 18 to rotate. The rotation of the impeller 18 drives the vertical rod 17 to rotate, which in turn drives the first bevel gear 19 to rotate. The first bevel gear 19 meshes with the second bevel gear 22, which in turn drives the rotating rod 20 to rotate. The rotating rod 20 then drives the vibrating component, causing the screen 7 to vibrate reciprocally. This helps the screen 7 shake off the droplets adhering to it, preventing them from being affected by the adhering medication when subsequent droplets impact the screen 7. This allows the patient to inhale smaller droplets of medication, facilitating the medication's entry into the patient's respiratory tract and lungs, and reducing adverse symptoms during nebulization therapy.

[0040] In one embodiment of the present invention, the vibration assembly includes a circular groove 23 and a circular rod 21. The circular groove 23 is located at one end of the rotating rod 20 outside the cavity 16. Pins 24 are symmetrically fixed on the inner wall of the circular groove 23. The circular rod 21 is fixedly connected to the side of the screen 7 facing the cavity 16. The end of the circular rod 21 away from the screen 7 is slidably inserted into the interior of the circular groove 23. The outer ring of the circular rod 21 is provided with a reciprocating thread, and both pins 24 are matched with the reciprocating thread. During operation, the rotating rod 20 drives the pins 24 to rotate. Through the matching of the pins 24 with the reciprocating thread and the fixed connection between the circular rod 21 and the screen 7, the vibration assembly is strengthened. Next, during the rotation of the pin 24, the round rod 21 can be driven to move back and forth, and the round rod 21 can drive the screen 7 to move back and forth. During the reciprocating movement of the screen 7, the droplets adhering to the screen 7 can be shaken off. The shaken-off droplets can be driven by the airflow to impact the screen 7 again, which helps to break up larger droplets, so that only small droplets of the correct size pass through the screen 7. This is beneficial for the patient to quickly enter the respiratory tract and lungs during nebulized inhalation therapy, thus helping to treat the patient and reduce adverse symptoms during nebulized inhalation.

[0041] In one embodiment of the present invention, the second atomizing mechanism includes a conical plate 25, which is fixed to the inner wall of the discharge pipe 4. A through hole is provided at the right end of the conical plate 25, and a first ring 26 is fixed to the outer wall of the right end of the conical plate 25. The through hole communicates with the inner ring of the first ring 26. A second ring 27 is fixed to the right end of the first ring 26 and is slidably connected to the round rod 21. A plurality of air outlet pipes are fixedly connected to the outer circumferential array of the first ring 26. 28. The first ring 26 is fitted around the outer ring of the round rod 21. The inner diameter of the first ring 26 is slightly larger than the outer diameter of the round rod 21. During operation, driven by the airflow, the liquid droplets in the bottle 1 enter the discharge pipe 4 and, along the conical plate 25, enter the inner ring of the first ring 26. Then, the airflow is discharged through the provided air outlet pipe 28. Because the diameter of the inner ring of the first ring 26 is relatively small, the airflow velocity increases to a high-speed airflow after entering the interior of the first ring 26. The high-speed airflow carries the medicine... As the liquid moves from the inside of the first ring 26 to the inside of the outlet pipe 28 and is ejected from the outlet pipe 28, smaller droplets can directly follow the high-speed airflow from the inside of the first ring 26 into the outlet pipe 28. For larger droplets, due to their greater inertia, the high-speed airflow carries them to collide with the bottom of the second ring 27. Under the impact of the high speed, the large droplets are dispersed into smaller droplets, which then enter the outlet pipe 28 under the influence of the high-speed airflow. As the high-speed airflow moves inside the outlet pipe 28, the airflow speed increases again, further dispersing the liquid droplets and making them even smaller. This facilitates the re-atomization of larger droplets generated during the initial nebulization process, as well as larger droplets that collide and aggregate during the movement of the liquid with the airflow, making them smaller and easier for the patient to absorb. This improves the effectiveness of nebulization therapy and reduces adverse symptoms during the nebulization process.

[0042] In one embodiment of the present invention, multiple air outlet pipes 28 are arranged at an angle. During operation, when the high-speed airflow is ejected from the air outlet pipe 28, it is easy to impact the inner wall of the discharge pipe 4, causing droplet aggregation and generating large droplets that are not easy for patients to inhale. This embodiment of the present invention can solve the above problems. The specific implementation is as follows: by setting the air outlet pipe 28 at an angle, the high-speed airflow ejected from the air outlet pipe 28 can be sprayed onto the inner wall of the discharge pipe 4 at an angle. Then, the airflow can flow along the inner wall of the discharge pipe 4 to form a vortex. The vortex can drive the ejected droplets to rotate and flow, thereby reducing the collision between the droplets and the inner wall of the discharge pipe 4. At the same time, the rotational flow of the droplets can reduce the collision between droplets, thereby reducing the aggregation of droplets, which is conducive to reducing the formation of large droplets and thus improving the effect of nebulization therapy.

[0043] In one embodiment of the present invention, a third ring 39 is rotatably connected to one end of the round rod 21 near the screen 7. A telescopic rod 29 is fixed to the inner wall of the round groove 23. A through-tube is provided inside the round rod 21. The telescopic end of the telescopic rod 29 extends into the through-tube and is rotatably connected to the screen 7. A first gear 30 is fixed to the outer ring of the telescopic end of the telescopic rod 29. A toothed rail 31 is provided on the inner ring of the third ring 39. A second gear 32 is rotatably connected to the inside of the through-tube through a mounting seat. The first gear 30 meshes with the second gear 32. An opening 33 is provided through the outer wall of the round rod 21 and is connected to the through-tube. The second gear 32 passes through the opening 33 and meshes with the toothed rail 31. Three cleaning rods 40 are fixed in a circumferential array on the outer ring of the third ring 39. All three cleaning rods 40 slide in contact with the screen 7. During operation, when droplets pass through the screen holes, the surface tension of the droplets is relatively high, causing them to adhere to the screen holes. The moisture on the screen will form a water film under the action of surface tension, covering the sieve holes. After the airflow carries the small droplets through the sieve holes with the water film, the small droplets and the water film will aggregate, resulting in the droplets becoming larger. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the rotation of the rotating rod 20 can drive the telescopic rod 29 inside the circular groove 23 to rotate, so that the telescopic end of the telescopic rod 29 can drive the first gear 30 to rotate. The first gear 30 drives the second gear 32 that meshes with it to rotate. The second gear 32 drives the toothed rail 31 that meshes with it to rotate. Then the toothed rail 31 drives the third ring 39 to rotate. The third ring 39 drives the cleaning rod 40 to rotate. The cleaning rod 40 moves along the surface of the screen 7, which can clean the water film generated on the surface of the sieve holes, thereby helping to reduce the aggregation and enlargement of droplets and water film, and thus helping to reduce the adverse effects on patients during nebulization treatment.

[0044] In one embodiment of the present invention, inclined guide plates 34 are fixed at the upper and lower ends of the outer ring of the cylinder 15. Limiting plates 35 are fixed at the edges of the two inclined guide plates 34, and the limiting plates 35 are rotatably sleeved on the outer ring of the rotating rod 20. During operation, as the airflow moves from the inside of the bottle 1 into the discharge pipe 4, two streams of airflow from the upper and lower parts of the bottle 1 collide with each other at the inlet of the discharge pipe 4, causing the droplets carried in the airflow to collide with each other and generate larger droplets. This embodiment of the present invention can solve the above problems. The specific implementation is as follows: the inclined guide plates 34 can guide the upper and lower airflows, so that the airflow can smoothly enter the discharge pipe 4. At the same time, the inclined guide plates 34 can block the two airflows, thereby reducing the collision of droplets and generating larger droplets, which is beneficial to improving the effect of nebulization therapy.

[0045] In one embodiment of the present invention, a plurality of fan blades 36 are fixed in a circumferential array on the outer ring of the rotating rod 20 near the end of the conical plate 25. A fixing block 41 is fixed on the inner ring of the conical plate 25, and a second circular hole 42 is opened through the middle of the fixing block 41. All the fan blades 36 are located inside the second circular hole 42. During operation, the rotation of the rotating rod 20 can drive the fan blades 36 to rotate. During the process of the airflow driving the droplets to move towards the inside of the first ring 26, the impact of the airflow can help the fan blades 36 rotate. During the rotation, the fan blades 36 can compress the air and move it to the right. The back of the fan blades reduces the air density. To replenish air and restore the original balance, the air to the right of the fan blade 36 is difficult to enter the left side of the fan blade 36 due to the obstruction of the fixed block 41. As a result, the air on the back moves to the right to replenish the airflow, which helps the airflow move towards the discharge pipe 4. This helps increase the speed of the airflow entering the inner ring of the conical plate 25, which helps to accelerate the movement speed of the airflow inside the first ring 26. This helps to improve the effect of secondary nebulization, which helps to reduce the number of large droplets inhaled by the patient during nebulization treatment, which helps to alleviate the adverse symptoms of the patient during nebulization treatment, and thus helps to improve the effect of nebulization treatment.

[0046] In one embodiment of the present invention, the reflux mechanism includes a reflux trough 38, which is fixed to the outer ring of the discharge pipe 4. The reflux trough 38 is located between the screen 7 and the conical plate 25, and one end of the reflux trough 38 away from the discharge pipe 4 is fixedly connected to the outer ring of the bottle body 1. During operation, when too much liquid medicine accumulates in the discharge pipe 4, small droplets moving with the swirling flow easily come into contact with the accumulated liquid medicine, thereby causing the small droplets to dissolve into the liquid medicine and reducing the amount of medicine in the aerosol. This embodiment of the present invention can solve the above problems. Specific implementation details are as follows: In the case of a large droplet shaken off by the screen 7 and unable to move with the airflow, the large droplet will flow along the inner wall of the discharge pipe 4 into the return trough 38 under the action of gravity, and then enter the medicine liquid along the return trough 38. This helps to prevent excessive accumulation of medicine liquid in the discharge pipe 4 from affecting the movement trajectory of the small droplets with the airflow, thus facilitating the reuse of the medicine liquid, reducing waste, and ensuring that the aerosol contains a sufficient amount of medicine, which is beneficial for patients to receive effective nebulization treatment.

[0047] Working principle of this invention:

[0048] The nebulizer breaks down the medication into small droplets or particles, or aerosols, with a diameter of a few micrometers. As the patient breathes, the medication directly enters the respiratory tract and lungs. Because aerosol particles aggregate upon collision, forming large droplets or aggregates, this process is extremely rapid. When the inhaled aerosol particles are large, these larger particles may cause spasms of the bronchial smooth muscle, leading to wheezing, primarily manifested as difficulty breathing. This embodiment of the invention can solve the above problems. The specific implementation is as follows: First, the user opens the top cover 2, adds the medication to the bottle 1, then closes the top cover 2, connects the air inlet pipe 6 to the compressor's outlet, and then starts the compressor. Compressed air from the compressor is introduced into the first nebulization mechanism through the air inlet pipe 6. In the first nebulization mechanism, the medication is atomized into small droplets and moved upwards by the airflow. The atomized droplets enter the discharge pipe 4. The second nebulization mechanism further atomizes the droplets during their movement by preventing them from colliding with each other. The large, polymerized droplets are re-atomized, turning them into smaller droplets. This helps reduce discomfort during nebulization therapy. The atomized droplets, driven by the airflow, impact the screen 7 inside the discharge pipe 4. Smaller droplets pass directly through the screen holes, while larger droplets, impacting the sidewall of the screen 7, are partially broken into smaller droplets that can pass through the screen holes, and some condense into water droplets on the screen 7. A vibration mechanism drives the screen 7 to vibrate reciprocally, shaking off the droplets adhering to it. Some of these droplets pass through the second atomization mechanism during their fall, where they are atomized again into smaller droplets by the airflow and pass through the screen holes. The remaining droplets flow along the discharge pipe 4 and are returned to the inside of the bottle 1 for re-atomization via a return mechanism. This process effectively breaks up the polymerized droplets generated during atomization, preventing patients from inhaling excessively large droplets and reducing adverse symptoms during nebulization therapy.
