Description

Technical Field

[0001] This application relates to the field of ultrasonic atomization equipment technology, and in particular to a portable ultrasonic atomization device for otolaryngology. Background Technology

[0002] The portable ultrasonic nebulizer for otolaryngology is a miniaturized and portable nebulization therapy tool designed specifically for otolaryngological diseases. Based on ultrasonic nebulization technology, the device converts electrical energy into high-frequency mechanical vibration through an nebulizer plate. The vibration of the metal plate of the nebulizer plate breaks the liquid medicine into fine droplets, which are then delivered directly to the lesion site by the airflow, achieving efficient local drug delivery.

[0003] In current common nebulizer designs, the nebulizing plate is usually fixed inside the device, and the direction of the aerosol cloud it generates is basically the same as the airflow direction inside the device, that is, it is arranged in a parallel co-flow manner. Under this design, the aerosol cloud generated by nebulization mainly relies on the patient's inhalation to be carried out from the outlet. This process is essentially a flat-push carrying in the form of laminar flow. Its mixing mechanism is highly dependent on molecular diffusion, so the mixing efficiency is low. It is difficult to achieve sufficient and rapid turbulent mixing between the airflow and the aerosol cloud, which is not conducive to maintaining the stability of the aerosol cloud. This causes the aerosol cloud to not have time to mix evenly with the air and directly impact the device tubing or the patient's oropharynx due to inertia, thus failing to reach the deep respiratory tract.

[0004] Therefore, we propose a new portable ultrasonic nebulization device for otolaryngology. Summary of the Invention

An adjustment mechanism for adjusting the axial position of the outer liner tube relative to the mixing tube is disposed at the end of the mixing tube.

[0008] The outer tube is connected to a connector at one end, and a liquid storage tank is connected to the bottom of the connector. A water pump is installed inside the lower part of the connector to transport the liquid medicine inside the liquid storage tank to the inner liner tube.

[0009] Preferably, the driving mechanism includes: a motor, a crank, a slider, and a connecting rod. The motor is fixedly installed on the inner wall of the protective cover. The crank and the motor are connected in a transmission relationship. The slider is slidably disposed inside the protective cover. The connecting rod connects the slider and the atomizing plate.

[0010] The outer wall of the slider is provided with a groove, and the crank is engaged in the groove on the outer wall of the slider.

[0011] Preferably, the opening at the end of the inner liner tube is aligned with the opening at the end of the outer liner tube, and the inner liner tubes are arranged in a ring outside the central axis of the outer liner tube.

[0012] Preferably, the adjusting mechanism includes: a second motor and a lead screw, the second motor being connected to the end of the mixing tube, the second motor and the lead screw establishing a transmission relationship, and one end of the lead screw passing through the mixing tube being inserted into the inside of the outer sleeve.

[0013] Preferably, the outer wall of the outer sleeve is provided with a guide block, the inner wall of the mixing tube is provided with a limiting frame, and the guide block is slidably disposed inside the limiting frame.

[0014] Preferably, a conduit is provided between the two opposing inner liner tubes. The conduit is coaxial with the outer liner tube, and both ends of the conduit are open. A guide block is connected to the end of the conduit away from the protective cover. The guide block has a conical structure, and the tip of the guide block faces the center point of the conduit.

[0015] The conduit is also equipped with a piston, which is connected to the connecting rod in the middle of the slider.

[0016] Preferably, the connecting seat has an air duct that runs through both sides, a fan is installed inside the air duct of the connecting seat, the end of the mixing pipe is provided with an air inlet facing the air duct of the connecting seat, the edge of the end of the protective cover is internally tangent to the air inlet of the mixing pipe, and an air inlet is provided at the center of the end of the protective cover.

[0017] Preferably, the atomizing plate is fitted with absorbent cotton on the side facing the protective cover, and the diameter of the atomizing plate is the same as the inner diameter of the inner liner tube.

[0018] Preferably, the second motor is embedded in the side wall of the connecting seat.

[0019] Preferably, the bottom of the water pump is connected to an inlet pipe, and one end of the inlet pipe is located inside the storage tank;

[0021] The bottom of the inner liner is provided with a return pipe, and the other end of the return pipe is located inside the liquid storage tank.

[0022] Compared with the prior art, this application has at least the following advantages:

[0023] In this invention, by setting up an inner liner tube, an atomizing plate, and a driving mechanism, the relative displacement of the atomizing plate relative to the inner liner tube is achieved by the cooperation of the driving structure and the atomizing plate. The displacement of the atomizing plate squeezes and forcibly agitates the liquid medicine and air inside the inner liner tube, ensuring that the atomizing plate achieves efficient atomization in the cavity of the inner liner tube, and concentrating the generated aerosol cloud in the inner liner tube to mix well with the air, thereby significantly increasing the overall concentration of aerosol inside the inner liner tube and enhancing the local drug delivery effect.

[0024] In this invention, by setting up an outer tube and a driving mechanism, the dynamic control of aerosol cloud storage, mixing, and discharge is achieved, which is precisely adapted to the patient's breathing process. The aerosol concentration is significantly increased through continuous accumulation. Combined with the nebulizer and inner tube, it achieves efficient mixing with air. The reciprocating movement of the outer tube satisfies the directional discharge of the stored aerosol cloud by squeezing it and forcibly agitating the air inside the tube, so that the air and aerosol are mixed efficiently again, thereby achieving the goal of optimizing inhalation efficiency and treatment experience.

[0025] In this invention, by setting up a conduit, a flow guide block, and a piston, the piston reciprocates to agitate the air, which in turn enhances the mixing of the airflow at the opening of the inner liner tube. The flow guide block guides the airflow to diffuse, actively creating a "forced mixing zone" to strengthen the mixing. This dual mechanism ensures that the aerosol and air are mixed more evenly and efficiently, ultimately improving the respiratory tract deposition rate and therapeutic effect of the drug in nebulized therapy.

[0039] The portable ultrasonic nebulizer for otolaryngology provided in this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this application.

[0040] like Figures 1-8 The portable ultrasonic nebulizer for otolaryngology is shown in the embodiment of this application. It includes an atomizing plate 1 and an inner liner tube 2. The atomizing plate 1 is slidably disposed inside the inner liner tube 2. An outer sleeve 3 is disposed outside the inner liner tube 2. A mixing tube 4 is disposed outside the outer sleeve 3. A vent hole is provided on the outer peripheral surface of the mixing tube 4. A protective cover 5 is connected to the end of the inner liner tube 2. A driving mechanism for driving the atomizing plate 1 to slide back and forth along the axis of the inner liner tube 2 is disposed inside the protective cover 5. An adjustment mechanism for adjusting the axial position of the outer sleeve 3 relative to the mixing tube 4 is disposed at the end of the mixing tube 4.

[0041] The end of the outer tube 3 is connected to a connecting seat 6, the bottom of the connecting seat 6 is connected to a liquid storage tank 601, and a water pump 602 is provided inside the lower part of the connecting seat 6 for transporting the liquid inside the liquid storage tank 601 to the inside of the inner liner tube 2.

[0042] One side of the connecting seat 6 is equipped with a battery and a control module for power supply and intelligent control of the entire equipment. In actual use, the liquid medicine is pumped into the inner liner tube 2 by the water pump 602. The inner liner tube 2 can be a cylindrical structure with an opening. The atomizing plate 1 can be flexibly moved along the central axis of the inner liner tube 2 under the action of the driving mechanism. When the atomizing plate 1 moves from the opening part of the inner liner tube 2 to the closed part, the atomizing plate 1 will squeeze the liquid medicine in the inner liner tube 2, so that the liquid medicine is forcibly stirred and the liquid medicine is fully distributed on the liquid contact surface of the atomizing plate 1. At this time, there is a cavity between the atomizing plate 1 and the opening part of the inner liner tube 2. Under the operation of the atomizing plate 1, the atomizing plate 1 continuously generates aerosol gas clouds in the cavity, increasing the concentration of aerosol gas clouds inside the inner liner tube 2.

[0043] Then, with the action of the driving mechanism, the atomizing plate 1 will move from the closed part of the inner liner tube 2 to the open part, which will force the aerosol gas cloud in the inner liner tube 2 to be discharged. After the aerosol gas cloud is discharged, it will mix with the surrounding air in real time at the open part of the inner liner tube 2.

[0044] As the atomizing plate 1 moves back and forth inside the inner liner tube 2, it can continuously stir the airflow at the opening of the inner liner tube 2 and continuously generate aerosol clouds as it continues to work, thereby obtaining a high concentration of aerosol clouds that are evenly mixed with the airflow.

[0045] The position of the outer tube 3 relative to the mixing tube 4 can be adjusted by the adjustment mechanism. When the outer tube 3 is located deep inside the mixing tube 4, the outer tube 3 is located relatively far away from the opening of the mixing tube 4. This allows the aerosol cloud at the opening of the outer tube 3 to be temporarily stored inside the mixing tube 4, which is beneficial to continuously increase the concentration of the aerosol cloud and the uniformity of the mixing of the aerosol cloud with the air. At this time, the patient can move the opening of the mixing tube 4 away from the mouth and nose, which also corresponds to the patient's exhalation process.

[0046] As the adjustment mechanism operates, the outer tube 3 can be moved from the depth inside the mixing tube 4 to the opening of the mixing tube 4. The aerosol air mass squeezed inside the mixing tube 4 is expelled outward through the outer tube 3. At this time, the outer tube 3 also forcibly agitates the air inside the mixing tube 4, causing the air to mix with the aerosol air mass again, achieving a better mixing effect. At this time, the patient can bring the opening of the mixing tube 4 close to the mouth and nose, which corresponds to the patient's inhalation process, thereby enabling the aerosol air mass to be inhaled into the respiratory tract, achieving a good nebulization treatment effect.

[0047] Since the position of the nebulizer 1 is adjustable, when the nebulizer 1 is located at the opening of the inner liner tube 2, and the inner liner tube 2 and the outer liner tube 3 are located at the opening of the mixing tube 4, the distance between the nebulizer 1 and the patient's mouth and nose is shortened. This reduces the problem of aerosol cloud deposition and loss in the tubing, helps control aerosol cloud loss, maintains aerosol cloud stability, and makes it easier to reach the deep respiratory tract, achieving better therapeutic effects.

[0048] In this embodiment, as Figures 2-10 As shown, the drive mechanism includes: motor 7, crank 701, slider 702 and connecting rod 703. Motor 7 is fixedly installed on the inner wall of the protective cover 5. Crank 701 and motor 7 establish a transmission relationship. Slider 702 is slidably disposed inside the protective cover 5. Connecting rod 703 connects slider 702 and atomizing plate 1.

[0049] The outer wall of the slider 702 is provided with a groove, and the crank 701 is engaged in the groove on the outer wall of the slider 702.

[0050] The crank 701 is driven to reciprocate by the motor 7. During the rotation of the crank 701, the part of the crank 701 embedded in the slide groove of the side wall of the slider 702 moves back and forth relative to the slider 702, which drives the slider 702 to reciprocate linearly relative to the inner liner tube 2. The atomizing plate 1 is driven to reciprocate inside the inner liner tube 2 by the connecting rod 703. The atomizing plate 1 stirs the air and aerosol gas in the inner liner tube 2, so that they are evenly mixed and maintain a high concentration.

[0051] Furthermore, the slider 702 is connected to multiple connecting rods 703, thereby enabling synchronous control and maintaining the accuracy and stability of the slider 702's movement.

[0052] The opening at the end of the inner liner tube 2 is aligned with the opening at the end of the outer liner tube 3, and the inner liner tube 2 is arranged in a ring outside the central axis of the outer liner tube 3.

[0053] The opening of the inner liner tube 2 is flush with the opening of the outer liner tube 3, so that when the gas at the opening of the inner liner tube 2 is agitated, the gas at the opening of the outer liner tube 3 is also in a flowing state, thus enabling good control of the mixing of aerosol gas clouds with air.

[0054] When the outer tube 3 is located at the opening of the mixing tube 4, the inner liner tube 2 is also located at the opening of the mixing tube 4, further shortening the distance between the atomizing plate 1 and the patient's mouth and nose. An elliptical protective mask is provided on the outside of the mixing tube 4, which can prevent the patient's mouth and nose from directly contacting the inner liner tube 2, thereby reducing the chance of contact between aerosol clouds and the tube wall, reducing deposition loss, and helping to maintain the stability of droplets.

[0055] The adjustment mechanism includes: a second motor 8 and a lead screw 801. The second motor 8 is connected to the end of the mixing tube 4. The second motor 8 and the lead screw 801 establish a transmission relationship. One end of the lead screw 801 passes through the mixing tube 4 and is inserted into the inside of the outer sleeve 3.

[0056] The outer wall of the outer sleeve 3 is provided with a guide block 301, and the inner wall of the mixing tube 4 is provided with a limit frame 401. The guide block 301 is slidably disposed inside the limit frame 401.

[0057] The screw 801 is driven to rotate by the motor 8. The screw 801 is rotatably connected to the mixing tube 4 through the bearing. The screw 801 is connected to the outer tube 3 through the thread. Thus, when the screw 801 rotates, it can drive the outer tube 3 to move in a straight line. By controlling the working direction of the motor 8 and adjusting the rotation direction of the screw 801, the movement direction of the outer tube 3 can be controlled. The movement of the outer tube 3 relative to the inside of the mixing tube 4 can agitate the air inside the mixing tube 4.

[0058] With the coordinated action of the guide block 301 and the limiting frame 401, the position and movement path of the outer tube 3 relative to the mixing tube 4 can be accurately limited, preventing the outer tube 3 from rotating with the lead screw 801.

[0059] A conduit 9 is also provided between the two opposing inner liner tubes 2. The conduit 9 is coaxially arranged with the outer sleeve tube 3. Both ends of the conduit 9 are open. The end of the conduit 9 away from the protective cover 5 is connected to a guide block 901. The guide block 901 has a conical structure and the tip of the guide block 901 faces the center point of the conduit 9.

[0060] A piston 902 is also provided inside the conduit 9, and the piston 902 is connected to the connecting rod 703 in the middle of the slider 702;

[0061] During the reciprocating linear motion of slider 702, connecting rod 703 can drive piston 902 to reciprocate relative to conduit 9. Piston 902 can agitate the air flow inside conduit 9. Since conduit 9 is provided with inner liner tubes 2 on both sides, when the air flows on both sides of conduit 9, it can further promote the air flow at the opening of inner liner tube 2, thereby further mixing the air at the opening of inner liner tube 2 with the aerosol air mass.

[0062] This includes the following: when the piston 902 moves toward the side closer to the guide block 901, the gas in the conduit 9 is guided by the guide block 901 when it is discharged, and the airflow moves toward the opening of the inner liner tube 2 in a diffusion trend, thereby actively creating a forced and efficient mixing zone, allowing the air and aerosol gas clouds to be strongly mixed, so as to achieve the purpose of uniform mixing.

[0063] The connecting seat 6 has a through air duct on both sides inside. A fan 603 is installed inside the air duct of the connecting seat 6. The end of the mixing pipe 4 is provided with an air inlet facing the air duct of the connecting seat 6. The edge of the end of the protective cover 5 is tangent to the air inlet of the mixing pipe 4. An air inlet is provided at the center of the end of the protective cover 5.

[0064] During the patient's inhalation, the outer tube 3 is moved to the opening of the mixing tube 4 by the adjustment mechanism. The fan 603 generates airflow, which flows through the air duct of the connecting seat 6 toward the mixing tube 4. The forced airflow further mixes with the aerosol gas mass inside the mixing tube 4 and promotes the discharge of gas inside the mixing tube 4, which facilitates the patient's inhalation and improves the drug delivery efficiency.

[0065] When the end of the protective cover 5 is attached to the end of the mixing tube 4, the air inlet of the mixing tube 4 is sealed under the cover of the protective cover 5, so the fan 603 cannot inject gas into the mixing tube 4, thereby reducing the loss of aerosol gas cloud in the mixing tube 4. At this time, corresponding to the patient's exhalation process, the atomizing plate 1 generates aerosol gas cloud inside the inner liner tube 2, and through the cooperation of the drive mechanism, improves the uniformity of the aerosol gas cloud mixing with air, and makes the outer tube 3 deep inside the mixing tube 4, so that the aerosol gas cloud is temporarily stored inside the mixing tube 4, waiting for the patient's inhalation process to be released.

[0066] A water-absorbing cotton is attached to the side of the atomizing plate 1 facing the protective cover 5, and the diameter of the atomizing plate 1 is the same as the inner diameter of the inner cavity of the inner liner tube 2.

[0067] By absorbing the liquid medicine with absorbent cotton, the liquid supply requirements of the atomizing plate 1 can still be met when the atomizing plate 1 is located at the opening of the inner liner tube 2, thereby maintaining the heat dissipation and continuous operation requirements of the atomizing plate 1 and ensuring the working efficiency of the atomizing plate 1.

[0068] Motor 28 is embedded in the side wall of connector 6;

[0069] The motor 8 is located outside the mixing tube 4 to ensure that the outer sleeve 3 can fit against the end of the mixing tube 4, thereby effectively sealing the air inlet at the end of the mixing tube 4 and preventing unnecessary airflow to reduce the loss of aerosol gas clouds inside the mixing tube 4.

[0070] The bottom of the water pump 602 is connected to a water inlet pipe 604, one end of which is located inside the liquid storage tank 601;

[0071] The side of the water pump 602 is provided with a water outlet pipe 605, and the other end of the water outlet pipe 605 is connected to the inner liner pipe 2.

[0072] The bottom of the inner liner tube 2 is provided with a return pipe 201, and the other end of the return pipe 201 is located inside the liquid storage tank 601;

[0073] The outlet pipe 605 is equipped with a connector, and each interface of the outlet pipe 605 corresponds to an inner liner pipe 2 to achieve individual liquid supply. The return pipe 201 is also equipped with a connector, and each interface of the return pipe 201 corresponds to an inner liner pipe 2 to achieve the recovery and treatment of excess liquid and reduce waste.

[0074] Meanwhile, the water outlet pipe 605 and the return pipe 201 are both located at the closed end of the inner liner pipe 2, so as to meet the needs of the atomizing plate 1 when it moves back and forth.
