Description

Technical Field

[0001] This invention belongs to the technical field of anesthetic drug nebulization devices, and particularly relates to an anesthetic drug nebulization device and its usage method. Background Technology

[0002] Anesthetic drug nebulization is the process of converting a solution of anesthetic drugs into an aerosol for inhalation administration to patients. Traditionally, anesthetic drug nebulization was performed using a ventilator, which nebulizes the drug into the patient's lungs via mechanical ventilation. To overcome these limitations, anesthetic drug nebulizers have been developed in recent years. These devices typically use ultrasound or mesh technology to atomize the drug solution, which is then inhaled through a dedicated tubing or mask. These devices offer a simpler and safer method of anesthetic drug administration.

[0003] When nebulizing anesthetics, the diameter of the nebulized droplets can affect the anesthetic effect. If the drug needs to be deposited deep in the lungs to achieve a systemic effect, smaller droplets are required. If the drug needs to be effective in a local area (such as the upper respiratory tract), larger droplets are required. Existing devices use a fixed diameter of the nebulized liquid when nebulizing anesthetic drugs. Although anesthesia can be performed according to a fixed standard, the anesthetic efficiency is reduced, leaving room for improvement and optimization of the treatment effect. Therefore, an anesthetic drug nebulization device and its usage method are proposed. Summary of the Invention

[0004] This invention addresses the problem in existing technologies where the droplet diameter of anesthetic drugs after atomization cannot be adjusted, and proposes the following technical solution:

[0005] An anesthetic drug nebulizer includes a nebulizer canister and an air compressor. An air supply pipe is fixedly connected between the nebulizer canister and the air compressor. A nozzle is fixedly connected to the bottom of the inner wall of the nebulizer canister. A liquid storage box is fixedly inserted into the inner wall of the nebulizer canister. A sealing mechanism is provided in the inner cavity of the nebulizer canister. A rotating rod is rotatably connected to the top of the nebulizer canister. An nebulizing plate is fixedly connected to the bottom end of the rotating rod. A baffle is fixedly inserted into the inner wall of the nebulizer canister. An aspiration tube and an infusion tube are fixedly connected to the side of the nebulizer canister. A return tube is fixedly connected to the side of the aspiration tube. The bottom end of the infusion tube extends into the interior of the liquid storage box. An adjusting rod is rotatably connected to the side of the return tube. A circular plate is fixedly connected to the bottom end of the adjusting rod. A sleeve is threadedly connected to the top of the infusion tube. A circular hole is opened at the top of the sleeve. A rubber pad is slidably provided on the inner side of the sleeve. A handle is fixedly installed on the outer side of the nebulizer canister.

[0006] Preferably, the sealing mechanism includes a first spring fixedly connected to the top of the inner wall of the nozzle, a pusher fixedly connected to the bottom end of the first spring, a plurality of cylinders fixedly connected to the top of the pusher, a conical head fixedly connected to the top of the pusher, sealing rings provided at the top and bottom of the conical head, a conical tube fixedly connected to the top of the nozzle, and a plurality of conical holes opened on the side of the conical tube.

[0007] Preferably, a pressure rod is slidably provided in the inner cavity of the rotating rod, a second spring is slidably sleeved on the side of the pressure rod, a limit groove is opened on the outer side of the rotating rod, a round rod is fixedly connected to the side of the pressure rod, a turntable is movably sleeved on the outer side of the rotating rod, a first spiral groove is opened on the inner wall of the turntable, and multiple scrapers are fixedly installed on the outer side of the turntable.

[0008] Preferably, the scraper has a spherical protrusion at the bottom, multiple ball-head rods are fixedly connected to the top of the baffle, and multiple rubber strips are fixedly connected to the bottom of the baffle.

[0009] Preferably, the inner wall of the mist suction pipe is provided with a second spiral groove, and the inner wall of the mist suction pipe is provided with a flow guide groove, which is connected to the second spiral groove. An S-shaped plate is fixedly installed on the inner wall of the mist suction pipe, and multiple through holes are provided on the side of the S-shaped plate.

[0010] Preferably, a guide tube is provided through the top of the sleeve, and the top of the guide tube is tapered.

[0011] Preferably, a conical cylinder is fixedly inserted into the side of the atomizing can, a circular plate is hinged to the side of the conical cylinder, a torsion spring is provided at the connection between the conical cylinder and the circular plate, an inclined groove is opened on the side of the conical cylinder, an L-shaped spring is fixedly installed on the side of the circular plate, a protrusion is provided on the side of the L-shaped spring, and the protrusion contacts the inclined groove, and a lever is rotatably connected to the side of the handle.

[0012] Preferably, the bottom of the atomizing plate has multiple through holes of different diameters, and the diameter of the rubber strip is smaller than the diameter of the through holes of the atomizing plate.

[0013] The present invention also provides a method of using the above-described anesthetic drug nebulizer, the method comprising the following steps:

[0014] Step 1: Adjust the diameter of the liquid atomization plate by rotating the lever, then adjust the mist discharge of the suction tube by rotating the adjusting rod, then align the needle containing the anesthetic drug with the round hole of the sleeve and inject the anesthetic drug into the infusion tube.

[0015] Step 2: Start the air compressor and input compressed air into the air supply pipe. The pusher body is pushed by the air and drives the conical head to rise. Then the air sprays the anesthetic drug in the conical tube out of the conical tube and causes the sprayed anesthetic drug to hit the bottom of the atomizing plate and form a mist.

[0016] Step 3: After nebulization, the anesthetic is expelled through the inhalation tube. The user holds the handle and puts the inhalation tube in their mouth to inhale the nebulized anesthetic.

[0017] Step 4: During inhalation, press down on the lever to rotate the disc, and use the scraper to scrape off and collect the anesthetic drugs adhering to the inner wall of the nebulizer.

[0018] Step 5: Press the lever to remove the L-shaped spring from contact with the inclined groove, and then deliver fresh air into the atomizing can through the conical tube;

[0019] Step Six: After anesthesia is complete, turn off the air compressor, remove the nebulizer from the user's hand, and then clean and disinfect the nebulizer.

[0020] The beneficial effects of this invention are as follows: when the air compressor is not in use, the conical head can effectively seal the conical tube, thereby ensuring that the anesthetic drug will not flow back into the gas delivery tube. In addition, the nebulizer plate can be rotated by the rotating rod, which can flexibly adjust the nebulization diameter of the anesthetic drug. At the same time, the inhalation volume of the inhalation tube can be precisely adjusted by rotating the adjusting rod, thereby significantly optimizing the anesthetic effect of the anesthetic drug.

[0021] By pressing down on the lever, the round rod drives the turntable to rotate through the first spiral groove. The scraper can scrape off the anesthetic drug condensed on the inner wall of the atomizing can, reducing waste and maximizing the utilization of the anesthetic drug. Furthermore, the scraper strikes the ball head rod, causing the rubber strip to insert into the through hole of the atomizing plate, thereby clearing the through hole of the atomizing plate for reuse and improving the practicality of the device.

[0022] The second spiral groove can recover and guide the anesthetic liquid condensed on the inner wall of the suction tube. The recovered anesthetic is blocked by the S-shaped plate, and the recovered anesthetic can be blown away and atomized again through the through holes of the S-shaped plate to ensure that the anesthetic is fully atomized to the greatest extent.

[0023] By pressing the lever, the L-shaped spring can be disengaged from the inclined groove. At this time, the circular plate no longer obstructs the conical cylinder, allowing air to enter the atomizing canister through the conical cylinder under negative pressure. This provides users with fresh air and reduces the odor of the air compressor itself, thereby reducing adverse reactions from users. Attached Figure Description

Multiple rubber strips 30 are fixedly connected to the bottom of the baffle 13. Multiple through holes of different diameters are opened at the bottom of the atomizing plate 12. The diameter of the rubber strips 30 is smaller than the diameter of the through holes of the atomizing plate 12. A second spiral groove 31 is opened on the inner wall of the suction pipe 14. The inner wall of the suction pipe 14 is provided with a guide groove, which is connected to the second spiral groove 31. An S-shaped plate 32 is fixedly installed on the inner wall of the suction pipe 14. Multiple through holes are provided on the side of the S-shaped plate 32. A guide tube 33 is provided through the top of the sleeve 19. The top of the guide tube 33 is tapered. A conical cylinder 34 is fixedly inserted into the side of the atomizing can 1. A circular plate 35 is hinged to the side of the conical cylinder 34. A torsion spring 36 is provided at the connection between the conical cylinder 34 and the circular plate 35. A slanted groove 37 is provided on the side of the conical cylinder 34. An L-shaped spring 38 is fixedly installed on the side of the circular plate 35. A protrusion is provided on the side of the L-shaped spring 38, and the protrusion contacts the slanted groove 37. A lever 39 is rotatably connected to the side of the handle 21.

[0041] Specifically, the different sizes of the anesthetic drug nebulizer liquid have different effects on drug deposition and efficacy. Smaller droplets (less than 5 micrometers) can penetrate deep into the small airways and alveoli of the lungs, thereby improving drug absorption and efficacy. Medium-sized droplets (5 to 10 micrometers) can deposit in the lungs and upper respiratory tract, thus having both local and systemic effects. Larger droplets (greater than 10 micrometers) mainly exert their effects in local areas, such as relieving upper respiratory tract symptoms. The top of the nebulizer plate 12 has three different sized through holes, each occupying one-third of the space of the nebulizer plate 12. The distribution angle and number of the three through holes are consistent, so as to adjust the nebulization diameter of the anesthetic drug according to actual needs. The baffle 13 is located above the nebulizer plate 12 and has a fan-shaped groove with an area of ​​one-third of the nebulizer plate 12. During use, the nebulization diameter of the nebulizer plate 12 can be adjusted by rotating the rotating rod 11. The side of the rotating rod 11 has a triangular arrow, and the top of the nebulizer canister 1 also has three triangular arrows. The three triangular arrows correspond to the three types of through holes in the atomizing plate 12. The atomization diameter of the atomizing plate 12 can be accurately adjusted using these arrows. Rotating the rotating rod 11 causes the atomizing plate 12 to rotate, positioning one of the three through holes below the fan-shaped groove. Anesthetic drugs can then be injected into the reservoir 5. An infusion tube 18 is fixedly connected to the side of the atomizing tube 14, with its bottom end penetrating into the reservoir 5. A spherical protrusion is provided on the side of the sleeve 19 to increase friction between the hand and the sleeve 19. The sleeve 19 can be removed from the infusion tube 18 by rotating it. The rubber pad 20 can be replaced after each atomization session. After the rubber pad 20 is inserted into the sleeve 19, the sleeve 19 is rotated and installed onto the infusion tube 18. A round hole is provided at the top of the sleeve 19. A needle containing anesthetic drugs is inserted into the sleeve 19 through this hole. The needle then passes through the rubber pad 20 and injects the anesthetic drugs into the reservoir 5 through the infusion tube 18. The inner cavity of the nebulizer 1 is equipped with a sealing mechanism to prevent the anesthetic drugs from flowing back into the gas delivery tube 3. When the anesthetic drugs in the reservoir 5 flow into the conical tube 9 through the conical hole 10, the bottom of the inner wall of the conical tube 9 is blocked by the conical head 8. Sealing rings are provided at both the top and bottom of the conical head 8 to prevent the anesthetic drugs from flowing downwards from the conical tube 9. Then, the air compressor 2 is started to input compressed air into the air supply pipe 3. The air supply pipe 3 is connected to the bottom end of the nozzle 4. After the air enters the nozzle 4, it pushes the pusher 7 to move upward. Multiple cylinders are fixedly connected to the top of the pusher 7, which creates a gap between the pusher 7 and the top of the inner wall of the nozzle 4 to ensure airflow. After the pusher 7 drives the conical head 8 to rise, the air enters the conical tube 9. The bottom of the conical head 8 is conical to ensure that the air can flow quickly when passing through the bottom of the conical head 8. Then, the anesthetic drug in the conical tube 9 is sprayed out by the air and impacts the atomizing plate 12, and is atomized through the through holes of the atomizing plate 12.The top of the reservoir 5 has multiple round holes. Anesthetic drugs not atomized at the bottom of the atomizing plate 12 flow back into the reservoir 5 through these holes. Anesthetic drugs atomized by the atomizing plate 12 are discharged through the inhalation tube 14. The user inhales the anesthetic drug from the inhalation tube 14 through their mouth to achieve an anesthetic effect. An adjusting rod 16 is rotatably connected to the side of the return tube 15. A circular disc 17 is fixedly connected to the bottom end of the adjusting rod 16. The bottom end of the return tube 15 is connected to the atomizing canister 1. The diameter of the end of the return tube 15 connected to the inhalation tube 14 is larger than the diameter of the bottom end. The circular disc 17 is located at the end of the return tube 15 with a larger diameter. The size of disc 7 matches the inner diameter of the return tube 15. When disc 17 completely blocks the return tube 15, its outer edge is made of rubber, thus improving the sealing effect of disc 17 on the return canister 15 and ensuring that the nebulized anesthetic drug does not enter the return tube 15. When the adjusting rod 16 is rotated, causing disc 17 to rotate, disc 17 will not completely block the return tube 15, allowing some anesthetic drug to be diverted by the return tube 15 and return to the nebulizer 1. This allows for adjustment of the inhalation volume of the inhalation tube 14 without reducing the nebulization quality, making it suitable for adults or children with different lung capacities.

[0042] Example 2:

[0043] Combination Figures 7 to 9 As shown, based on Embodiment 1, a pressure rod 22 is slidably provided in the inner cavity of the rotating rod 11, a second spring 23 is slidably sleeved on the side of the pressure rod 22, a limit groove 24 is opened on the outer side of the rotating rod 11, a round rod 25 is fixedly connected to the side of the pressure rod 22, a turntable 26 is movably sleeved on the outer side of the rotating rod 11, a first spiral groove 27 is opened on the inner wall of the turntable 26, and multiple scrapers 28 are fixedly installed on the outer side of the turntable 26.

[0044] Specifically, a pressure rod 22 is slidably disposed within the inner cavity of the rotating rod 11. A second spring 23 is slidably sleeved on the side of the pressure rod 22. One end of the second spring 23 is fixedly connected to the top of the rotating rod 11, and the other end of the second spring 23 is fixedly connected to the bottom of the pressure rod 22. A limiting groove 24 is formed on the outer side of the rotating rod 11. A round rod 25 is fixedly connected to the side of the pressure rod 22. The round rod 25 passes through the limiting groove 24 and is located on the outer side of the rotating rod 11. A turntable 26 is movably sleeved on the outer side of the rotating rod 11. A first spiral groove 27 is formed on the inner wall of the turntable 26. The end of 5 is located at the top of the inner side of the first spiral groove 27. When the pressure rod 22 is pressed down, the round rod 25 causes the turntable 26 to rotate through the first spiral groove 27. Multiple scrapers 28 are fixedly installed on the outer side of the turntable 26. The scrapers 28 are L-shaped. When the turntable 26 rotates, the scrapers 28 can scrape off the anesthetic liquid attached to the top and inner wall of the nebulizer 1. The anesthetic liquid is then dropped back onto the storage box 5 by the nebulizer plate 12 for recycling. This reduces the loss of anesthetic liquid and greatly improves the utilization rate of anesthetic liquid.

[0045] Example 3:

[0046] Combination Figure 5 and Figure 7 As shown, based on Embodiment 1, the bottom end of the scraper 28 is provided with a spherical protrusion, the top of the baffle 13 is fixedly connected with multiple ball-head rods 29, the bottom of the baffle 13 is fixedly connected with multiple rubber strips 30, and the bottom of the atomizing plate 12 is provided with multiple through holes of different diameters. The diameter of the rubber strips 30 is smaller than the diameter of the through holes of the atomizing plate 12.

[0047] Specifically, the scraper 28 has a spherical protrusion at its bottom end, and multiple ball-head rods 29 are fixedly connected to the top of the baffle 13. The relative horizontal distance between the diameter of the spherical protrusion and the ball-head rods 29 is less than zero. When the scraper 28 rotates, the spherical protrusion can contact the ball-head rods 29 and impact them, causing the baffle 13 to vibrate. Multiple rubber strips 30 are fixedly connected to the bottom of the baffle 13. The rubber strips 30 are distributed at the same angle as the through holes of the atomizing plate 12, and the diameter of the rubber strips 30 is smaller than the diameter of the through holes of the atomizing plate 12. The rubber strip 30 is made of soft and flexible material. When one of the atomizing plates 12 is rotated to the area below the fan-shaped groove on the baffle 13, the rubber strip 30 can be inserted into the remaining two through holes of the atomizing plate 12. When the baffle 13 is vibrated by the ball head rod 29, the baffle 13 will cause the rubber strip 30 to shake, so that the rubber strip 30 can be inserted into the through hole of the atomizing plate 12 and clear the through hole, so as to ensure the atomization effect of the atomizing plate 12, so that the device can be reused and the service life of the device can be improved.

[0048] Example 4:

[0049] Combination Figure 10As shown, based on Embodiment 1, the inner wall of the mist suction pipe 14 is provided with a second spiral groove 31, and the inner wall of the mist suction pipe 14 is provided with a guide groove, which is connected to the second spiral groove 31. An S-shaped plate 32 is fixedly installed on the inner wall of the mist suction pipe 14, and multiple through holes are provided on the side of the S-shaped plate 32.

[0050] Specifically, the inner wall of the aspiration tube 14 is provided with a second spiral groove 31. Some of the anesthetic adhering to the inner wall of the aspiration tube 14 is collected by the second spiral groove 31 and flows to the bottom of the second spiral groove 31. A guide groove is provided on the inner wall of the aspiration tube 14, which is connected to the bottom of the second spiral groove 31. The guide groove allows the anesthetic collected by the second spiral groove 31 to be gathered together. An S-shaped plate 32 is fixedly installed on the inner wall of the aspiration tube 14, and multiple through holes are provided on the side of the S-shaped plate 32. 2 can prevent the anesthetic drug in the guide channel from flowing back from the suction tube 14 into the nebulizer 1. When the air and anesthetic drug are discharged from the suction tube 14, the S-shaped plate 32 can intercept part of the air and make it discharge from the through hole of the S-shaped plate 32. The air velocity after being discharged through the through hole of the S-shaped plate 32 increases, so that the anesthetic drug in the guide channel continuously impacts the connection between the second spiral groove 31 and the guide channel, and is dispersed into a mist under the action of impact force, so that it can be inhaled by the user again, thereby further reducing the loss of anesthetic drug.

[0051] Example 5:

[0052] Combination Figure 6 As shown, based on Embodiment 1, a guide tube 33 is provided through the top of the sleeve 19, and the top of the guide tube 33 is tapered.

[0053] Specifically, a guide tube 33 is provided through the top of the sleeve 19. The top of the guide tube 33 is tapered. The guide tube 33 facilitates the guidance of the needle, allowing it to be quickly inserted into the infusion tube 18. When the anesthetic dose is insufficient, the guide tube 33 can quickly replenish the reservoir 5 to achieve the anesthetic effect. When the rubber pad 20 needs to be replaced, the sleeve 19 is first removed from the infusion tube 18. At this time, the rubber pad 20 is stuck inside the sleeve 19. By pushing the guide tube 33, the rubber pad 20 can be pushed out of the sleeve 19 to facilitate the replacement of the new rubber pad 20.

[0056] Specifically, a conical cylinder 34 is fixedly inserted into the side of the atomizing can 1. A circular plate 35 is hinged to the side of the conical cylinder 34, which blocks the opening of the conical cylinder 34. A torsion spring 36 is provided at the connection between the conical cylinder 34 and the circular plate 35. One end of the torsion spring 36 is fixedly connected to one side of the conical cylinder 34, and the other end is fixedly connected to one side of the circular plate 35. A slanted groove 37 is provided on the side of the conical cylinder 34. An L-shaped spring piece 38 is fixedly installed on the side of the circular plate 35. The side of the L-shaped spring piece 38 has a protrusion that contacts the slanted groove 37. By locking the end of the L-shaped spring piece 38 into the slanted groove 37, the circular plate 35 is locked. A lever 39 is rotatably connected to the side of the handle 21. The bottom of the lever 39... A circular rod is fixedly connected to the side, located inside the handle 21, which restricts the angle of the lever 39. By pressing the lever 39, the bottom end of the lever 39 approaches the nebulizer 1, while the upper end of the lever 39 contacts the L-shaped spring 38. The L-shaped spring 38 is squeezed by the lever principle, and the L-shaped spring 38 is separated from the inclined groove 37. Then, the torsion spring 36 pulls the circular plate 35 to rotate, and the circular plate 35 is never in contact with the conical cylinder 34. Then, the air flow inside the nebulizer 1 generates negative pressure, which mixes the air outside the nebulizer 1 with the conical cylinder 34. This can reduce the odor brought by the air compressor 2 and mix the anesthetic drug with the awakening air, making the user's inhalation more natural and reducing the patient's adverse reactions.

[0057] Example 7:

[0058] The present invention also provides a method of using the above-described anesthetic drug nebulizer, the method comprising the following steps:

[0059] Step 1: Adjust the diameter of the liquid atomization plate 12 by rotating the rotating rod 11, then adjust the mist discharge of the suction tube 14 by rotating the adjusting rod 16, then align the needle containing the anesthetic drug with the round hole of the sleeve 19 and inject the anesthetic drug into the infusion tube 18.

[0060] Step 2: Start the air compressor 2 to input compressed air into the air supply pipe 3. The pusher 7 is pushed by the air and drives the conical head 8 to rise. Then the air sprays the anesthetic drug in the conical tube out of the conical tube and makes the sprayed anesthetic drug hit the bottom of the atomizing plate 12 to form a mist.

[0061] Step 3: After nebulization, the anesthetic is discharged through the inhalation tube 14. The user holds the handle 21 and puts the inhalation tube 14 in their mouth, inhaling the nebulized anesthetic into their body.

[0062] Step 4: During inhalation, press down on lever 22 to rotate disc 26, and scrape off and collect the anesthetic drugs adhering to the inner wall of nebulizer 1 using scraper 28;

[0063] Step 5: Press the lever 39 to prevent the L-shaped spring 38 from contacting the inclined groove 37, and then deliver fresh air into the atomizing can 1 through the conical cylinder 34;

[0064] Step 6: After anesthesia is completed, turn off the air compressor 2, remove the nebulizer 1 from the user's hand, and then clean and disinfect the nebulizer 1.

[0065] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
