Description

Technical Field

[0001] The present invention relates to the technical field of thoracic surgery, and in particular to an atomization device for assisting postoperative care in thoracic surgery. Background Art

[0002] After thoracic surgery, patients often experience problems such as limited respiratory function and difficulty in coughing up sputum. The nebulizer can atomize drugs or saline into tiny particles, which directly act on the respiratory tract to help dilute sputum and promote sputum discharge, thereby alleviating respiratory obstruction and relieving cough and dyspnea.

[0003] At present, the existing nebulizer device used to assist postoperative care of thoracic surgery is difficult to produce uniform nebulized particles, and is unable to further refine the nebulized particles. Particles of different sizes are easily produced during the nebulization process. Uneven nebulized particles can easily lead to uneven distribution of drugs in the respiratory tract, making it impossible for certain parts (such as the small bronchi and alveoli in the lungs) to receive sufficient drug coverage, thereby reducing the treatment effect. Patients after thoracic surgery are prone to the risk of lung infection. The nebulized particles are not fine enough, and the drugs cannot effectively reach the infected parts of the lungs, which can easily lead to difficult-to-control infections, making the nebulizer device less practical.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. The present invention sets a multi-layer first extrusion plate and a second extrusion plate, sets a microchannel in the through hole of the second extrusion plate, sets a conical second air hole on the first extrusion plate, and refines the atomized particles multiple times through the air holes and the microchannel, so that the liquid medicine particles are more uniform and fine, and can be more effectively absorbed after inhalation by the patient, thereby improving the bioavailability of the drug. At the same time, the uniform and fine particles can cover a larger lung area, which helps to improve the effectiveness of the drug and enhance the therapeutic effect.

[0024] In summary, the present invention extrude and refine the atomized particles through the refinement mechanism, thereby improving the atomization quality. The voltage plate and the rubber pad cooperate to achieve resonance, further enhancing the refinement effect, and improving the uniformity of the atomized particles, making the medicine liquid particles more uniform and fine, which is beneficial to the patient's inhalation and drug absorption. When the extrusion block and the extrusion plate return to their positions, the inner wall is cleaned to achieve the secondary utilization of large-particle atomized medicine liquid, thereby enhancing the practicability of the equipment.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Reference Figures 1 to 9 A nebulizer device for assisting postoperative care in thoracic surgery comprises a shell 1, an air compressor 5 is fixedly installed at the bottom of the shell 1, the air compressor 5 is a power source for providing compressed air, an air inlet 2 is arranged at the top of the shell 1, an inhalation cover 4 is arranged on the side wall of the shell 1, and a patient inhales atomized liquid medicine through the inhalation cover 4, a mounting shell 3 is fixedly installed on the side wall of the shell 1, a funnel-shaped liquid medicine pool 10 is arranged inside the shell 1, a ventilation pipe 9 is fixedly connected to the bottom of the liquid medicine pool 10, and the ventilation pipe 9 is away from the liquid medicine pool 10 One end of the housing 1 is fixedly connected to the air compressor 5, a nozzle 12 is arranged inside the liquid medicine pool 10, the bottom of the nozzle 12 is fixedly connected to the top of the ventilation pipe 9, a plurality of water suction pipes 11 are fixedly installed on the side wall of the nozzle 12, and a plurality of water suction pipes 11 are distributed in a circular array on the outer wall of the nozzle 12, and the bottom pipe opening of the water suction pipe 11 is located below the liquid surface of the liquid medicine, and a gas screen 6 is fixedly installed on the top of the inner wall of the housing 1, and the gas screen 6 is used to prevent the liquid medicine from backflowing and guide the air flow downward. The inner wall of the housing 1 is fixedly installed with a ventilation screen 6. The ventilation plate is located below the air screen 6, and the bottom of the ventilation plate is fixedly connected to the air cylinder 7. The function of the air cylinder 7 is to stabilize the internal air pressure and stabilize the internal airflow. The bottom of the inner wall of the air cylinder 7 is fixedly installed with an air plate 8. The function of the air plate 8 is to refine the air flow. The center of the bottom circle of the air plate 8 is fixedly connected with a partition 13. The partition 13 is located above the water suction pipe 11 and the nozzle 12. The interior of the partition 13 is provided with an airflow regulating valve 14. The function of the airflow regulating valve 14 is to control the flow of the airflow and ensure the internal pressure. In order to ensure stability (this is a prior art and will not be described in detail here), a baffle 15 is fixedly installed at the bottom of the air plate 8, and the baffle 15 is located on the periphery of the partition 13. The air compressor 5 generates compressed air, which enters the nozzle 12 through the ventilation pipe 9. Through the negative pressure generated between the nozzle 12 and the water suction pipe 11, the water suction pipe 11 sucks the liquid medicine upward to impact the partition 13, and it becomes a very fine mist and is sprayed to the outside. The sprayed atomized liquid medicine passes through the baffle 15 for initial screening (the same principle as the compression atomizer in the prior art, which will not be described in detail here).

[0038] A motor 17 is fixedly installed inside the mounting shell 3, and a bidirectional screw rod 16 is fixedly connected to the output end of the motor 17. The bidirectional screw rod 16 is vertically arranged inside the mounting shell 3 and is rotatably connected to the mounting shell 3. The two ends of the bidirectional screw rod 16 are rotatably connected to a first connecting block 18 and a second connecting block 21 respectively. The first connecting block 18 and the second connecting block 21 are slidably connected to the outer shell 1. The first connecting block 18 is located below the second connecting block 21. An extrusion block 19 is fixedly connected to the side of the first connecting block 18 close to the air cylinder 7. The extrusion block 19 is slidably connected to the inner wall of the outer shell 1. The extrusion block 19 is sleeved on the outer wall of the air cylinder 7 and is slidably connected to the air cylinder 7. A first air hole 2 is opened on the extrusion block 19. 0, the mist medicine after the initial screening by the baffle 15 passes upward through the first air hole 20 and enters the top of the extrusion block 19. The bottom of the extrusion block 19 is set as a groove. When the motor 17 is started, the bidirectional screw 16 rotates. Due to the movement of the extrusion block 19, the mist medicine at the bottom is adsorbed in the groove. As the extrusion block 19 rises, the medicine is brought into the upper part of the extrusion block 19, thereby realizing the adsorption and upward transportation of the medicine liquid, avoiding the medicine from remaining due to inertia or gravity during the movement, thereby improving the utilization rate of the medicine liquid. In this way, the medicine liquid can be evenly pushed to the subsequent processing part, ensuring the uniformity of the medicine liquid during the output process and reducing the waste caused by the residual medicine liquid.

[0039] Two first extrusion plates 22 are provided on one side of the second connecting block 21 close to the air cylinder 7. The two first extrusion plates 22 are slidably connected to the inner wall of the outer shell 1. The two first extrusion plates 22 are distributed up and down. A second extrusion plate 29 is provided between the two first extrusion plates 22. The second extrusion plate 29 is slidably connected to the inner wall of the outer shell 1. The second extrusion plate 29 is fixedly connected to the second connecting block 21. Two groups of sliding components are provided on the second connecting block 21. The two groups of sliding components correspond to the two first extrusion plates 22 respectively. The sliding components include a sliding groove 27 provided on the second connecting block 21. The sliding groove 27 is slidably connected to a sliding plate 25. The sliding plate 25 is fixedly connected to the first extrusion plate 22. The sliding plates 25 in the two groups of sliding components are fixedly connected to the second connecting block 21 on one side close to each other. A spring 26 is connected, the two first extrusion plates 22 and the second extrusion plate 29 are both annular, and are sleeved on the outer wall of the air cylinder 7 and are slidably connected to the air cylinder 7. A voltage assembly is respectively arranged on the side where the two first extrusion plates 22 are close to each other, and the voltage assembly includes three annular voltage plates 23, and the three voltage plates 23 have different diameters. The three voltage plates 23 are evenly distributed along the periphery of the first extrusion plate 22 toward the center of the circle. A rubber pad 24 is fixedly installed on the side of the voltage plate 23 close to the second extrusion plate 29, and a second air hole 28 is respectively arranged on the two first extrusion plates 22. The second air hole 28 is conical, and the inner diameter of the second air hole 28 gradually increases in the direction away from the second extrusion plate 29. A through hole is arranged on the second extrusion plate 29, and a microchannel 30 is arranged on the inner wall of the through hole.

[0040] The motor 17 is started, and the bidirectional screw 16 rotates, so that the first connecting block 18 and the second connecting block 21 are close to each other to squeeze the gas between them (smaller molecules or molecular clusters leave the atomizer head under the suction force generated by the negative pressure and the airflow. This is because smaller droplets have a larger surface area to volume ratio and are more significantly affected by the negative pressure and airflow. They can quickly obtain sufficient kinetic energy to overcome the adhesion and surface tension inside the liquid. Larger droplets cannot leave the atomizer head smoothly due to their larger mass). The first connecting block 18 drives the extrusion block 19 to move upward, and the second connecting block 21 drives the two first extrusion plates 22 and the second extrusion plates 29 to move downward. The second air hole 28 and the first air hole 20 are staggered up and down to form a more complex airflow pattern, which is conducive to the uniform distribution and stable flow of the atomized liquid, and can also reduce the amount of liquid. The liquid gathers at the hole, thereby reducing the risk of blockage, making it easier for the liquid medicine to pass through the hole, and maintaining good fluidity even when the viscosity of the liquid medicine is high. When the gas passes upward through the second air hole 28 on the first extrusion plate 22 at the lower end, the flow aperture of the gas gradually decreases. According to the continuity equation in fluid mechanics, the gas flow rate must be increased to keep the flow rate unchanged. This increase in flow rate will cause a higher speed and pressure difference at the orifice. After passing through the first extrusion plate 22 at the lower end, the gas enters the through hole in the second extrusion plate 29. The microchannel 30 further refines the atomized particles. When the atomized particles pass through the microchannel 30, due to the narrowness and tortuosity of the channel, the particles are squeezed and collided in the channel, which helps to refine the particles, thereby improving the atomization quality, making the liquid medicine particles more uniform, and facilitating patient inhalation.

[0041] The first extrusion plate 22 at the lower end moves downward to squeeze the gas while being subjected to upward pressure. Under the action of the sliding assembly, the first extrusion plate 22 at the lower end squeezes the second extrusion plate 29 upward, and the rubber pad 24 on the first extrusion plate 22 at the lower end squeezes the second extrusion plate 29 upward, and the rubber pad 24 is simultaneously subjected to the downward extrusion force of the second extrusion plate 29. When the pressure on the rubber pad 24 comes from the first extrusion plate 22 below it and the second extrusion plate 29 above it, the rubber pad 24 will produce stronger vibrations. This enhanced vibration can break the intermolecular viscous connection in the atomized liquid, making the atomized particles finer, thereby improving the refinement effect of the atomization. Since the three annular voltage plates 23 with different inner diameters are progressively distributed along the periphery of the first extrusion plate 22 toward the center of the circle , so that the vibration can be evenly transmitted on the entire plane of the first extrusion plate 22 at the lower end, ensuring that the energy of the vibration can be effectively distributed to the entire device, reducing the situation where local vibration is too strong or insufficient, thereby improving the atomization effect, and can effectively reduce the size difference of the atomized particles, so that the particle size inhaled by the patient is more consistent, and the uniform particle size can improve the bioavailability of the drug and enhance the therapeutic effect. Due to the enhancement and uniform distribution of the vibration, the distribution range of the atomized particles in the space can be expanded, so that the atomized drug can cover a larger area and improve the effectiveness of the drug. At the same time, by combining the rubber pad 24 and the voltage plate 23, the structural stability of the entire system is improved, reducing the vibration loss and noise during the working process, and making the equipment more reliable during operation.

[0042] When the first extrusion plate 22 at the lower end contacts the extrusion block 19, the spring 26 has a buffering effect, and then changes the movement direction of the first connecting block 18 and the second connecting block 21, so that the extrusion block 19 moves downward, and the two first extrusion plates 22 and the second extrusion plates 29 move upward, and the larger atomized particles on the inner wall of the shell 1 will be scraped off by the extrusion block 19, the first extrusion plate 22 and the second extrusion plate 29, and finally fall into the medicine liquid pool 10 to achieve secondary utilization. When the upper first extrusion plate 22 moves upward to squeeze the gas at its upper end, it is subjected to downward pressure, causing the upper first extrusion plate 22 to slide downward, and the gas is further refined when passing through the upper first extrusion plate 22, the second extrusion plate 29 and the lower first extrusion plate 22, which is the same as the distance of the first extrusion plate 22 moving downward to squeeze the gas and refine the medicine.

[0043] In the present invention, first, after the air compressor 5 is started, it sucks in air and compresses the air. After the air is compressed, it moves upward along the vent pipe 9 to the nozzle 12. Six groups of water suction pipes 11 are arranged around the nozzle 12. The air inlet 2 is used to introduce air to keep the airflow inside the shell 1 stable. The introduced air interacts with the airflow in the atomizing device to maintain pressure balance. At the same time, the introduced airflow interacts with the drug solution in the atomizing device to enhance the atomization effect of the drug. When the airflow passes through the drug solution, shear force and turbulence are generated, so that the drug solution is dispersed into tiny particles. The compressed air generated by the air compressor 5 is ejected from the nozzle 12, and the drug solution is sucked upward by the negative pressure generated between the nozzle 12 and the water suction pipe 11. The sucked-up drug solution impacts the upper partition 13 and becomes extremely fine mist and is ejected to the outside. This is the prior art. The atomized drug solution passes through the baffle 15, and the baffle 15 performs a preliminary screening on the atomized aerosol to separate some larger atomized particles.

[0044] The motor 17 is started, and the bidirectional screw 16 rotates, so that the first connecting block 18 drives the extrusion block 19 to move upward. When the extrusion block 19 moves upward, due to the pressure, the bottom groove structure thereof will absorb the molecules under negative pressure and pass upward through the first air hole 20, and the atomized particles enter the space between the first connecting block 18 and the second connecting block 21. The second connecting block 21 moves downward at the same time, and the second air hole 28 and the first air hole 20 are staggered, so that the molecules between the first connecting block 18 and the second connecting block 21 are squeezed. When the gas passes through the second air hole 28 on the first extrusion plate 22 at the lower end, the flow area of ​​the gas gradually decreases, and the flow rate of the gas gradually increases. The conical second air hole 28 can generate a stable pressure difference, so that the atomization process is more stable. The inner wall of the through hole of the second extrusion plate 29 is provided with a microchannel 30. The microchannel 30 causes the atomized particles to be squeezed and decomposed again when passing through the through hole, so that the atomized particles are collided and partially refined.

[0045] During the downward movement of the second connecting block 21, due to the negative pressure, the first extrusion plate 22 at the lower end will be pressed upward, so that the rubber pad 24 on the first extrusion plate 22 at the lower end squeezes the second extrusion plate 29 upward, and the rubber pad 24 is simultaneously subjected to the downward pressure of the second extrusion plate 29, so that the voltage plate 23 connected to the rubber pad 24 is subjected to the force of extrusion and vibration, and the three voltage plates 23 are progressively distributed along the periphery of the first extrusion plate 22 toward the center of the circle, so that the vibration propagates more evenly on the entire plane of the first extrusion plate 22 at the lower end, increasing the range in which the atomized particles are affected by the vibration, thereby improving the refinement effect, and at the same time increasing the uniformity of the atomized particles so that there will not be a large difference, so that the particle size inhaled by the patient is more uniform, and this amplified vibration can better break the sticky connection between molecules, making the atomized particles easier to be refined.

[0046] When the first extrusion plate 22 at the lower end contacts the extrusion block 19, the spring 26 will buffer the force exerted on the first extrusion plate 22 to reduce the possibility of damage thereof. Subsequently, the first connecting block 18 and the second connecting block 21 move away from each other and return to their original positions. While returning to their original positions, the larger atomized particles on the inner wall of the outer shell 1 will be scraped off by the extrusion block 19, the first extrusion plate 22 and the second extrusion plate 29, and finally fall into the medicine liquid pool 10 for secondary utilization. The first extrusion plate 22 at the upper end will be pressed downward when rising, thereby forming vibration, and the molecules above it will be further refined. Afterwards, due to the principle of pressure difference, the atomized particles are discharged from the inhalation mask 4 and inhaled by the patient.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
