Abstract
Description
Technical Field
[0001] This invention relates to the field of medical nebulizers, and more particularly to a medical water mist generator for use in sterilization environments. Background Technology
[0002] A medical nebulizer is a device that converts liquid medications into tiny aerosol particles (mist). Inhaled, the medication is directly deposited in the respiratory tract or lungs. It mainly consists of a pump, an nebulizing assembly, and a fan. The pump draws the liquid medication to the nebulizing assembly. When the piezoelectric ceramic plate of the nebulizing assembly is energized, it generates high-frequency ultrasonic vibrations that break the surface tension of the medication, forming an aerosol. Finally, the fan blows the aerosol out for the patient's use. Water mist generators used for humidification use ordinary or pure water for nebulization. The liquefied medications in medical nebulizers include solutions and suspensions.
[0003] When existing medical nebulizers atomize a suspension formed by mixing multiple medications, the mixed suspension is usually placed into the water tank of the nebulizer. This causes the effective drugs in the suspension to float or settle, resulting in a reduction in the therapeutic effect after atomization. Summary of the Invention
[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a medical water mist generator for sterilization environments.

[0015] According to the technical solution provided in the embodiments of this application, the atomizing box is further provided with a sterilization mechanism. The atomizing box includes a main body and an upper cover. The sterilization mechanism includes:
[0016] The spraying assembly includes four second branch pipes located on the four sides of the upper cover. Each second branch pipe has a transverse liquid outlet facing the top surface of the atomizing box and a longitudinal liquid outlet facing the outer wall of the atomizing box. A sleeve is uniformly rotatably fitted on each second branch pipe, and a spraying element is provided on the sleeve.
[0017] The four first branch pipes are connected at one end to each of the second branch pipes, and at the other end to the outlet pipe.
[0018] A switch assembly for closing or opening the connection between each of the first branch pipes and the outlet pipe.
[0019] According to the technical solution provided in the embodiments of this application, the switch assembly includes an adjusting inner ring disposed inside the water outlet pipe and corresponding to the end position of the first branch pipe. The bottom of the adjusting inner ring is provided with a switch port. Positioning washers are embedded in the inner wall of the water outlet pipe corresponding to the edges of each first branch pipe, and positioning pads are provided between adjacent positioning washers.
[0020] The atomizing box is provided with an adjusting outer ring fitted outside the water outlet pipe. A number of outer magnets are evenly arranged on the inner wall of the adjusting outer ring, and a number of inner magnets are evenly arranged on the top outer wall of the adjusting inner ring. Each of the outer magnets corresponds to each of the inner magnets and attracts each other.
[0021] According to the technical solution provided in the embodiments of this application, the top of the water outlet pipe is provided with an adjustment component. The adjustment component includes a fixed plate disposed inside the water outlet pipe. The fixed plate is evenly divided into four areas, of which two non-adjacent areas are liquid outlet areas. A plurality of liquid outlet holes are evenly arranged in the liquid outlet areas.
[0022] A micro motor is installed in the middle of one end of the fixed disk. The output shaft of the micro motor passes through the fixed disk and is fitted with a collar. The side surface of the collar is provided with two fan-shaped blocking plates that correspond to the two liquid outlet zones respectively.
[0023] According to the technical solution provided in the embodiments of this application, the medicine box is provided with a horizontal partition in the middle, and a mixing chamber is below the horizontal partition. Several longitudinal partitions are evenly arranged at the top of the horizontal partition along the second direction. The longitudinal partitions divide the space above the horizontal partition into several liquid medicine chambers. The air outlet pipe and the air inlet pipe both pass through the longitudinal partitions to connect the horizontal partitions with the mixing chamber. A first drain valve is provided on the horizontal partition at the position corresponding to each liquid medicine chamber.
[0024] According to the technical solution provided in the embodiments of this application, a number of baffles are evenly arranged in an alternating pattern in the middle of the top surface of the return flow inclined plate.
[0025] Compared with the prior art, the beneficial effects of the present invention are:
[0026] 1. This invention features a two-stage mixing process for the drug solution. The first stage involves gas entering the mixing chamber through the inlet pipe and exiting through the outlet pipe, thus mixing the drug solution. The second stage involves the mixed drug solution falling into the nebulizer box and flowing back down along the return slope and return port to the tail end of the nebulizer box. The mixed drug solution falls to the bottom of the nebulizer box and mixes with the base solution. Then, a water pump draws the mixed solution from the head end of the nebulizer box, creating a circulating flow that further mixes the base solution and the mixed drug solution. This ensures thorough mixing of the drug solution and solves the problem of existing medical nebulizers directly using the mixed drug solution, which leads to the rise or deposition of effective drugs in the mixed drug solution after long-term storage. This effectively improves the nebulization efficiency of the drug solution.
[0027] 2. Based on the above-mentioned secondary mixing, the circulating mixed liquid drives the drive blades and vertical shaft to rotate. Then, through the transmission of the first transmission structure, the main shaft, the second transmission structure and the branch shaft, the airflow fan blades are driven to rotate, so that an airflow is formed around the central channel inside the inner box. The heat inside the inner box exchanges heat with the heat dissipation fins, and then the heat dissipation fins on the outer wall of the inner box exchange heat with the mixed liquid, which achieves the purpose of cooling and heat dissipation, ensuring that there is a good electrical operating environment inside the inner box and avoiding damage to electrical components due to overheating.
[0028] 3. When cleaning the surface of the medical nebulizer, the nozzle is aligned with the horizontal or vertical liquid outlet by rotating the sleeve, and the base solution is sprayed onto the top or side surface of the nebulizer box to clean the surface. In the prior art, additional cleaning solution and container are required. Users are not only prone to spilling the container, but also need to wipe evenly. In this invention, only the corresponding sleeve needs to be adjusted to spray the base solution onto the corresponding position, so that the wiping is more even. For a small amount of stains, it can also be cleaned quickly and accurately. In addition, the sterilization mechanism is also equipped with a switching mechanism. Through the mutual attraction of the inner and outer magnets, rotating the outer ring of the adjustment mechanism drives the inner ring of the adjustment mechanism to rotate, so that the switch port is connected to different first branch tubes, which makes it easier to control the flow direction of the solution, making cleaning more accurate and operation more convenient.
[0029] In summary, the rapid and accurate cleaning by the sterilization mechanism enables this application to be used in sterile environments. Furthermore, the mixing of the drug solution by the auxiliary and dosing mechanisms ensures more complete atomization of the mixed drug solution, improving the atomization effect and thus enhancing the therapeutic effect after atomization.

[0053] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
[0054] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0055] Please refer to Figures 1-12 An embodiment of the present invention provides a medical water mist generator for sterilization environments, comprising:
[0056] Atomizing box 1 has a head end and a tail end along a first direction; the first direction is Figure 1 The atomizing box 1 is located in the left-right direction. The front end is the right end of the atomizing box 1, and the rear end is the left end of the atomizing box 1. The atomizing box 1 includes a main box body 11, an upper box cover 13 located at the top of the main box body 11, a drain valve 14 located at the bottom of the main box body 11, and several casters 12. The position of the atomizing box 1 can be moved by the casters 12, and the solution inside the atomizing box 1 can be drained and cleaned by the drain valve 14 to avoid the mixing of medicine and mutual interference when used multiple times.
[0057] The atomizing mechanism 2 includes an inner box 21 located at the center of the bottom surface inside the atomizing box 1, and a mist discharge pipe 26 located on the top surface of the front end. A water pump 23 is installed inside the inner box 21. The water pump 23 has an outlet pipe 25 extending upwards and communicating with the mist discharge pipe 26, and an inlet pipe 24 extending towards the front end and penetrating out of the inner box 21. An ultrasonic vibrating plate 28 is installed inside the mist discharge pipe 26, and a fan 27 is located at the bottom of the mist discharge pipe 26. The outlet of the water discharge pipe 25 is located between the fan 27 and the ultrasonic vibrating plate 28. The water pump 23 draws the liquid medicine or base solution from inside the atomizing box 1 and sends it to the mist discharge pipe 26. Inside the outlet pipe 26, a portion of the liquid medicine droplets are blown upwards by the fan 27. After passing through the ultrasonic vibrating plate 28, they form mist droplets, which are then discharged from the top opening of the mist outlet pipe 26 along with the rising airflow. In addition, a first one-way filter valve 29 is installed at the top left end of the main housing 11 to ensure the cleanliness of the airflow entering the atomizing box 1. Optionally, a connecting hose can be detachably installed at the top of the mist outlet pipe 26 to facilitate guiding the atomized mist to the place where it is needed. In addition, an electrical control module 22 is also installed inside the inner housing 21. The electrical control module 22 is used to control the start and stop of the fan 27, water pump 23 and ultrasonic vibrating plate 28. The electrical control module 22 can be a common electrical control system, which will not be described in detail here.
[0058] Auxiliary mechanism 3 includes a return slope 31 located at the top of the atomizing box 1. The return slope 31 extends downward from the first end towards the tail end. A return port 32 is provided at the tail end position of the return slope 31. A middle channel 33 extending in a second direction is provided in the middle of the inner box 21. Two baffles 34 connected to the two side walls of the inner box 21 are respectively provided in the middle of the two inner walls along the second direction. The first direction and the second direction are perpendicular to each other. (Reference) Figure 2 and Figure 3The solution is pumped into the mist discharge pipe 26 by the water pump 23. The solution falls from the mist discharge pipe 26 to the return slope 31. The solution flows to the left and flows downward through the return port 32. Because the water pump 23 draws the solution from the head end, the solution in the left half is affected by the baffle 34, flows through the middle channel 33, and then flows to the water pump 23 to form a circulating solution flow, which serves the purpose of mixing the medicine.
[0059] The dosing mechanism 5 includes a medicine box 51 located on the side of the mist discharge pipe 26 away from the tail end. The medicine box 51 has a mixing chamber 53 inside. An air inlet pipe 56 communicating with the inside of the mist discharge pipe 26 is located in the middle of the mixing chamber 53. Air outlet pipes 511 communicating with the outside are located on both sides of the mixing chamber 53 corresponding to the air inlet pipe 56. A valve passage communicating with the inside of the atomizing box 1 is located at the bottom of the mixing chamber 53. Figure 2 , Figure 9 and Figure 10 As shown, the valve channel includes a second drain valve 510 located at the bottom of the medicine box 51 and an upward drain hole 59 located on the upper cover 13. By opening the second drain valve 510, the medicine can be added into the atomizing box 1. After adding various medicines into the medicine box 51, a flange cover 210 is installed at the top of the mist discharge pipe 26. The fan 27 is turned on, so that the airflow flows into the mixing chamber 53 through the air inlet pipe 56. The airflow will be sprayed out from the air outlet pipe 511. After the airflow is disturbed, the medicines in the mixing chamber 53 are mixed.
[0060] refer to Figures 1 to 12 This invention features a two-stage mixing process for the drug solution. First, gas enters the mixing chamber 53 through the inlet pipe 56 and exits through the outlet pipe 511, mixing the drug solution with the gas. Second, the mixed drug solution falls into the nebulizer 1, flowing back along the return slope 31 and return port 32 to the tail end of the nebulizer 1. The mixed drug solution then mixes with the base solution at the bottom of the nebulizer 1. A water pump 23 then draws the mixed solution from the head end of the nebulizer 1, creating a circulating flow that further mixes the base solution and the mixed drug solution. This ensures thorough mixing of the drug solution, solving the problem of existing medical nebulizers directly using the mixed drug solution, which leads to the rise or deposition of effective drugs in the mixed solution after long-term storage. This effectively improves the nebulization efficiency of the drug solution.
[0061] In some embodiments, the bottom of the mixing chamber 53 is also provided with a drug delivery tube 517 that penetrates the medicine box 51 and extends into the mist discharge pipe 26. The end of the drug delivery tube 517 away from the mist discharge pipe 26 is sealed and slidably connected to a piston 514. The end of the drug delivery tube 517 located inside the mist discharge pipe 26 is provided with a plurality of fine holes 516 evenly. The end of the drug delivery tube 517 located inside the medicine box 51 is provided with a liquid inlet 513 that penetrates through it.
[0062] like Figures 1 to 12As shown, this application has a first method of using the liquid medicine. After the liquid medicine is mixed inside the mixing chamber 53, the second drain valve 510 is opened, and the liquid medicine can be put into the atomizing box 1. The liquid medicine can be atomized by the water pump 23. In this embodiment, there is also a second method of using the liquid medicine. The piston 514 is provided with a push rod 515 on the end face away from the fine hole 516. The mixed liquid medicine in the mixing chamber 53 will flow into the delivery tube 517 through the liquid inlet 513. By pushing the push rod 515, the piston 514 is moved towards the fine hole 516, and the mixed liquid medicine is discharged from the fine hole 516. Then, after being blown upward by the fan 27, it can be vibrated by the ultrasonic vibrating plate 28 to form droplets. This realizes two methods of using the liquid medicine. The first method is used for continuous atomization of a large amount of liquid medicine, while the second method is used for short-term atomization of a small amount of liquid medicine, which is convenient for flexible use according to different situations.
[0063] In some embodiments, a switching assembly 6 is provided near the tail end of the return slope 31. The switching assembly 6 includes a drain port 61 located on the side wall of the main housing 11 and above the return slope 31. An L-shaped channel 62 is provided between the drain port 61 and the return port 32. A sealing elastic sheet 64 is provided inside the L-shaped channel 62. A reset spring 63 connected to the top end of the L-shaped channel 62 is provided at the top of the sealing elastic sheet 64. An operating rod 65 is provided at the end of the sealing elastic sheet 64 away from the return slope 31.
[0064] like Figure 2 and Figure 11 As shown, pulling down the operating lever 65 stretches the return spring 63, pulling the sealing elastic piece 64 located in the vertical part of the L-shaped channel 62 to the horizontal part of the L-shaped channel 62. This opens the drain port 61 and closes the return port 32. This operation is used for short-term atomization of a small amount of medicine. On the one hand, it prevents the medicine from flowing to the lower part of the atomizing box 1 through the return port 32. On the other hand, it can also recycle the medicine that has not been fully atomized, improving the convenience of using the medicine. In addition, when the operating lever 65 is released, the elastic stress of the return spring 63 returning to its original shape will drive the sealing elastic piece 64 to reset, which will not interfere with the first method of using the medicine.
[0065] In some embodiments, a horizontal partition 52 is provided in the middle of the medicine box 51, and a mixing chamber 53 is below the horizontal partition 52. A plurality of longitudinal partitions 54 are evenly arranged at the top of the horizontal partition 52 along the second direction. The longitudinal partitions 54 divide the space above the horizontal partition 52 into a plurality of liquid medicine chambers 55. The air outlet pipe 511 and the air inlet pipe 56 both pass through the longitudinal partitions 54 to connect the horizontal partition 52 with the mixing chamber 53. A first drain valve 58 is provided on the horizontal partition 52 at the position corresponding to each liquid medicine chamber 55.
[0066] like Figure 9 and Figure 10As shown, each medicine chamber 55 on the medicine box 51 is fitted with a graduated glass plate 518, which allows observation of the liquid content inside the medicine chamber 55 and facilitates accurate addition of a fixed amount of liquid. In addition, since the air outlet pipe 511 and the air inlet pipe 56 pass through the longitudinal partition 54 and the transverse partition 52, they are not disconnected from the medicine chamber 55, thus avoiding uncertainty in the liquid volume. More preferably, there are two air inlet pipes 56, each with a side air port 57 at the bottom. The side air ports 57 of the two air inlet pipes 56 discharge air in opposite directions, which facilitates thorough mixing of the liquid. The top of the air outlet pipe 511 is equipped with a third one-way valve 512 to prevent unclean air from entering the mixing chamber 53.
[0067] In some embodiments, the auxiliary mechanism 3 further includes an airflow assembly and heat dissipation fins. The airflow assembly drives the gas inside the inner casing 21 to flow around the central channel 33. The heat dissipation fins are uniformly disposed on the inner and outer walls of the inner casing 21. The extending direction of the heat dissipation fins is parallel to the gas flow or liquid flow direction. Figure 2 As shown, the heat dissipation fins inside the inner casing 21 exchange heat with the flowing gas, and then the heat dissipation fins outside the inner casing 21 exchange heat with the flowing solution, thereby achieving the purpose of cooling and heat dissipation. This ensures that the inner casing 21 has a good operating environment for electrical components and avoids damage to electrical components due to overheating. In addition, since the extension direction of the heat dissipation fins is parallel to the direction of gas flow or liquid flow, the resistance of the heat dissipation fins is reduced, ensuring the smooth flow of gas and liquid.
[0068] In some embodiments, the airflow assembly includes two vertical shafts 35 arranged along the second direction on both sides of the middle channel 33. The two ends of the vertical shafts 35 extend along the third direction and into the interior of the inner box 21. The top and bottom of the inner box 21 are provided with main shafts 38 extending along the second direction. Each main shaft 38 has a plurality of branch shafts 39 arranged along the second direction on the side away from each other. The axis of the branch shafts 39 extends in the first direction. One end of each branch shaft 39 is equipped with an airflow fan blade 311. The airflow directions of the airflow fan blades 311 located at the top and bottom of the inner box 21 are opposite.
[0069] A drive blade 36 is provided in the middle of the vertical shaft 35 at the position of the middle channel 33. The end of the vertical shaft 35 is connected to the corresponding main shaft 38 through a first transmission structure 37. The main shaft 38 is connected to the corresponding branch shaft 39 through a second transmission structure 310.
[0070] like Figure 2 , Figure 3 and Figure 4As shown, the upper airflow fan blade 311 blows air to the right, and the lower airflow fan blade 311 blows air to the left, forming a circulating airflow around the central channel 33 inside the inner casing 21. The circulating mixed liquid drives the drive blade 36 and the vertical shaft 35 to rotate. This rotation, through the first transmission structure 37, the main shaft 38, the second transmission structure 310, and the branch shaft 39, drives the airflow fan blade 311 to rotate, creating an airflow around the central channel 33 inside the inner casing 21. Heat inside the inner casing 21 exchanges with the heat dissipation fins, and then heat is exchanged between the heat dissipation fins on the outer wall of the inner casing 21 and the mixed liquid. This achieves unpowered driving, with the pump 2 moving synchronously with the circulating mixed liquid. 3. After shutdown, both liquid and gas circulation will stop, allowing for flexible use. Optionally, the first transmission structure 37 and the second transmission structure 310 are special worm gear structures. A worm gear is installed at the end of the vertical shaft 35, and a corresponding worm is mounted on the main shaft 38. Through a special tooth design, the worm gear drives the worm, achieving not only transmission but also acceleration. The main shaft 38 rotates faster than the vertical shaft 35. The special tooth design is existing technology and will not be elaborated here. The worm gear of the second transmission structure 310 is installed on the main shaft 38, and the corresponding worm is installed on the branch shaft 39, also achieving acceleration and ensuring that the airflow fan blades 311 maintain high-speed operation to form airflow.
[0071] In some embodiments, the atomizing box 1 is further provided with a sterilization mechanism 4. The atomizing box 1 includes a main body 11 and an upper cover 13. The sterilization mechanism 4 includes:
[0072] The spraying assembly 43 includes four second branch pipes 431 located on the four sides of the upper cover 13. Each second branch pipe 431 is provided with a transverse liquid outlet 432 facing the top surface of the atomizing box 1 and a longitudinal liquid outlet 433 facing the outer wall of the atomizing box 1. Each second branch pipe 431 is uniformly rotatably fitted with a sleeve 434, and the sleeve 434 is provided with a spraying element.
[0073] The four first branch pipes 41 are connected at one end to each of the second branch pipes 431, and at the other end to the outlet pipe 25.
[0074] Switch assembly 42 is used to close or open the connection between each first branch pipe 41 and the outlet pipe 25;
[0075] like Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, during use, by operating the switch assembly 42, the corresponding first branch pipe 41 is selected, opening its connection with the water outlet pipe 25, while the other first branch pipes 41 remain closed. The sleeve 434 on the second branch pipe 431 corresponding to the first branch pipe 41 is moved to connect the sprayer with the transverse liquid outlet 432. After the sprayer sprays out the solution, it cleans the top surface of the atomizing box 1. Rotating the sleeve 434 connects the sprayer with the longitudinal liquid outlet 433, and after the sprayer sprays out the solution, it cleans the side of the atomizing box 1. Depending on the selected sprayer, not only is an additional container unnecessary, but specific small-area cleaning of different locations can also be performed, improving the convenience and flexibility of sterilization cleaning. Optionally, the sprayer includes a first fan-shaped nozzle 435 and a second fan-shaped nozzle 436, both of which have several diffusion spray channels 437 inside to increase the diffusion range. A second one-way valve 438 is provided at the outlet of the spray channel 437 to prevent external dirt or airflow from flowing back into the second branch pipe 431.
[0076] In some embodiments, the switch assembly 42 includes an adjusting inner ring 422 disposed inside the water outlet pipe 25 and at the position corresponding to the end of the first branch pipe 41. The bottom of the adjusting inner ring 422 is provided with a switch port 428. Positioning washers 426 are embedded in the inner wall of the water outlet pipe 25 at the edges of each first branch pipe 41, and positioning pads 427 are provided between adjacent positioning washers 426.
[0077] Above the atomizing box 1 is an adjusting outer ring 424 fitted outside the water outlet pipe 25. Several outer magnets 425 are evenly arranged on the inner wall of the adjusting outer ring 424, and several inner magnets 423 are evenly arranged on the top outer wall of the adjusting inner ring 422. Each outer magnet 425 corresponds to each inner magnet 423 and they attract each other.
[0078] like Figure 2 and Figure 6 As shown, rotating the outer adjusting ring 424 causes the inner adjusting ring 422 to move synchronously because each outer magnet 425 corresponds to and attracts each inner magnet 423. Since positioning washers 426 are embedded in the inner wall of the water outlet pipe 25 at the edges of each first branch pipe 41, and positioning pads 427 are provided between adjacent positioning washers 426, there is obvious resistance and a sense of engagement when the switch port 428 is rotated and coincides with the positioning washers 426 or positioning pads 427. The user can adjust according to the feel. When the positioning pads 427 coincide with the switch port 428, the purpose of sealing all first branch pipes 41 is achieved. Optionally, a mark is provided at the top of the outer adjusting ring 424 corresponding to the position of the switch port 428 to make it easier to understand the position of the switch port 428 more accurately. Optionally, the inside of the water outlet pipe 25 is provided with a limiting groove 421 that fits with the inner adjusting ring 422 to improve the stability of the inner adjusting ring 422 during rotation.
[0079] In some embodiments, the top of the water outlet pipe 25 is provided with an adjustment component 7. The adjustment component 7 includes a fixed plate 71 disposed inside the water outlet pipe 25. The fixed plate 71 is evenly divided into four regions, of which two non-adjacent regions are liquid outlet regions. A plurality of liquid outlet holes 73 are evenly arranged in the liquid outlet regions.
[0080] A micro motor 72 is installed in the middle of one end of the fixed plate 71. The output shaft of the micro motor 72 passes through the fixed plate 71 and is fitted with a collar 74. The side surface of the collar 74 is provided with two fan-shaped blocking plates 75 that correspond to the two liquid outlet zones respectively.
[0081] like Figure 9 and Figure 12 As shown, the micro motor 72 drives the collar 74 and two fan-shaped blocking plates 75 to rotate. The two fan-shaped blocking plates 75 can completely block all the liquid outlet holes 73 in the two liquid outlet zones. However, as the collar 74 and the fan-shaped blocking plates 75 rotate, different numbers of liquid outlet holes 73 are exposed, which makes it easy to adjust the water outlet speed and water outlet volume, and easy to adjust the aerosol content according to the situation.
[0082] In some embodiments, a number of baffles 8 are evenly arranged in a staggered pattern in the middle of the top surface of the reflux inclined plate 31, so that the liquid medicine passing through the reflux inclined plate 31 is dispersed by the baffles 8 and can be evenly dispersed to each reflux port 32, thereby improving the mixing uniformity.
