Description

Technical Field

[0001] This invention relates to the field of atomization device technology, and more specifically, to a mechanically pressurized spray device and method suitable for respiratory medicine. Background Technology

[0002] Mechanically pressurized nebulizers are key equipment in respiratory treatment. They increase airflow pressure mechanically to atomize drug solutions into tiny particles, making them easier for patients to inhale. The device is equipped with a precision airflow channel and nozzle, which can efficiently produce fine and uniform atomized particles that reach deep into the respiratory tract, improving treatment effectiveness. At the same time, it is easy to operate and suitable for patients of different ages.

[0003] Patent application CN202110769878.1 discloses a respiratory nebulizer that facilitates filter cartridge replacement and maintenance. The device includes a housing, a support column fixedly connected to the bottom surface of the housing, a medicine storage tank connected to the upper end of the support column, a filter cartridge mechanism located on the upper inner side of the medicine storage tank, and an inner wall cleaning mechanism. This respiratory nebulizer facilitates filter cartridge replacement and maintenance, thereby effectively improving the efficiency of filter cartridge replacement and maintenance.

[0004] Mechanically pressurized spray devices typically employ a fixed internal airflow baffle design. This may prevent the achievement of ideal atomization effects when handling medications with specific requirements for atomized particle size, thus limiting treatment efficiency. Furthermore, after a period of use, some medications are prone to condensation on the inner wall of the device's cup. This not only leads to medication waste and reduces the cost-effectiveness of treatment but may also affect the airflow channel due to the accumulation of condensate, thereby weakening the atomization effect and adversely impacting the patient's experience and treatment outcomes.

[0005] In view of this, we propose a mechanically pressurized spray device and method suitable for respiratory medicine. Summary of the Invention

[0016] In the technical solution of the present invention, the connecting pipe includes an outer air pipe that is snapped and fixed at the bottom opening of the drug delivery hopper, an inner tube disposed inside the outer air pipe, and a number of guide vanes regularly distributed between the outer air pipe and the inner tube.

[0017] In the technical solution of the present invention, the bottom of the rotating nozzle is rotatably connected to the inner side of the rotating groove, and the interior of the rotating nozzle is provided with an air jet port that runs vertically through it. The docking ring is fixed to the inner wall of the air jet port by a protrusion on the outer side wall. The rotating fan blade is integrally formed with the docking ring. One end of the scraper is fixed to the outer side wall of the rotating nozzle, and the other end abuts against the inner wall of the fixed cup body.

[0018] In the technical solution of the present invention, the inner tube body is snapped and fixed at the top opening of the fixed cup body, the two limiting clamps are snapped and fixed on the bottom surface of the inner tube body and have a connecting groove inside for providing a placement area for the internal structure of the airflow blocking mechanism, the docking nozzle body is rotatably connected between the two limiting clamps, the docking nozzle body has several vertically penetrating suction grooves inside, and an external protrusion is integrally formed on the outer side wall of the docking nozzle body.

[0019] In the technical solution of the present invention, the movable frame is slidably connected to the inside of the connecting groove, and the elastic force provided by the pressure spring is used to push the movable frame to move towards the docking nozzle. A guide bracket is snapped onto the top surface of the movable frame, and a fixed tooth plate is fixed to a movable rod that is slidably connected to the top wall of the connecting groove.

[0020] In the technical solution of the present invention, the actuating part further includes a fixing strip that is snapped and fixed to the top surface of the two limiting clamps. The inside of both ends of the fixing strip is provided with a placement groove for providing a rotation range for the rod gear. A rotating rod is sleeved inside the rod gear, and the rod gear meshes with the fixed gear plate.

[0021] In the technical solution of the present invention, a dial is provided above the rotating rod and the central rod of the dial is rotatably connected to the groove wall of the fixed strip placement groove.

[0023] On the other hand, the present invention provides a mechanically pressurized spray method suitable for respiratory medicine, employing the aforementioned mechanically pressurized spray device suitable for respiratory medicine, and comprising the following steps:

[0024] S1. First, pour the medicine into the inside of the fixed cup, and then insert the inner tube into the top opening of the fixed cup.

[0025] S2. Next, connect both ends of the ventilation hose to the air outlet of the air compressor and the bottom of the connecting pipe, respectively, and turn on the air compressor to send the compressed airflow into the interior of the connecting pipe.

[0026] S3. After the airflow passes through the bottom of the connecting pipe, it will be divided into two streams by several regularly distributed guide vanes, flowing upward from the outer air pipe and the inner pipe respectively.

[0027] S4. Subsequently, the airflow in the inner tube will directly enter the inner side of the docking ring. By rotating the fan blade, the docking ring and the rotating nozzle will rotate, which will also cause the scraper to rotate. During the rotation of the crossbar at the bottom of the scraper, the docking nozzle body will also rotate.

[0028] S5. As the docking nozzle rotates, the outer protrusion will abut against the moving frame. With the help of the pressure spring, the moving frame will reciprocate inside the connecting groove, causing the position of the fixed tooth plate to move up and down.

[0029] S6. After that, the fixed toothed plate that moves up and down will drive the rod gear to rotate, which will drive the mating gear to rotate faster, and then drive the dial along with the lever to rotate, thereby driving the entire blocking part to rotate.

[0030] S7. At this time, the continuously flowing airflow will draw the medicine in the medicine guide bucket upward from the medicine suction groove in the mouthpiece body. After hitting the blocking part, the medicine will be atomized. The user can inhale the generated mist into the lungs by covering the mouthpiece with their mouth.

[0031] S8. Subsequently, the drug droplets condensed on the inner wall of the fixed cup will also flow back into the drug guide hopper under the action of the scraper.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. The mechanical pressurized spray device and method applicable to respiratory medicine, after the airflow enters the rotating nozzle through the connecting pipe, the rotating fan blade will drive the entire rotating mechanism to rotate, so that the scraper will cause the condensed droplets on the inner wall of the fixed cup to flow back into the inside of the drug delivery hopper, thereby avoiding drug waste and weakening of the nebulization effect, thus ensuring the patient's user experience and treatment effectiveness.

[0034] 2. The mechanical pressurized spray device and method applicable to respiratory medicine, wherein the rotating nozzle drives the docking nozzle body to rotate together, and after the power is transmitted through the transmission part and the actuating part, the blocking part moves back and forth as a whole, thereby ensuring that the interaction between the airflow and the liquid medicine is more sufficient and uniform, thereby improving the atomization effect of the medicine.

Detailed Implementation

[0052] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0053] Please see Figures 1-15 As shown, this embodiment provides a technical solution:

[0054] A mechanically pressurized spray device suitable for respiratory medicine includes an air compressor 100, an atomizing device 300 for placing medicine, and a ventilation hose 200 connected between the air outlet of the air compressor 100 and the atomizing device 300.

[0055] In this invention, the atomizing device 300 includes a medicine cup 310, a connecting pipe 320 for providing a connection point for the ventilation hose 200, a rotating mechanism 330 disposed on the bottom surface inside the medicine cup 310, and an airflow blocking mechanism 340 disposed above the rotating mechanism 330.

[0056] Specifically, the medicine cup 310 includes a fixed cup body 311, a medicine guide 315 for storing medicine, and several balls 316 regularly distributed on the bottom surface inside the medicine guide 315.

[0057] Furthermore, an oral tube 312 and a hand handle 313 are integrally formed on the outer wall of the fixed cup body 311. A hand handle 314 is snapped and fixed on the outer side of the bottom cup mouth of the fixed cup body 311. The medicine guide hopper 315 is integrally formed with the hand handle 314. A rotating groove 3150 is opened on the inner bottom surface of the medicine guide hopper 315. A ball bearing 316 is rotatably connected to the inner side wall of the rotating groove 3150.

[0058] Furthermore, the fixed cup 311 provides a placement area for the medication, and the patient covers the mouthpiece 312 with their mouth to allow the nebulized medication to enter the lungs. The handle 313 is used to make it convenient for the patient to hold the fixed cup 311 when adding medication, the handpiece 314 provides a holding area for the patient during use, the medication guide 315 is used to concentrate the medication, and the ball bearing 316 is used to reduce the friction of the overall rotation of the rotating mechanism 330.

[0059] In this embodiment, as Figure 6 As shown, the connecting pipe 320 includes an outer air pipe 321 that is snapped and fixed at the bottom opening of the medicine guide hopper 315, an inner tube 322 disposed inside the outer air pipe 321, and a number of guide vanes 323 regularly distributed between the outer air pipe 321 and the inner tube 322.

[0060] Furthermore, the two ends of the ventilation hose 200 are connected to the air outlet of the air compressor 100 and the bottom of the connecting pipe 320, respectively. The air compressor 100 is turned on to send the compressed air into the interior of the connecting pipe 320. After the air passes through the bottom of the connecting pipe 320, it passes through several regularly distributed guide vanes 323 and the air will be divided into two streams, which flow upward from the interior of the outer air pipe 321 and the inner air pipe 322, respectively.

[0061] In this embodiment, as Figure 7 As shown, the rotating mechanism 330 includes a rotating nozzle 331 rotatably connected to the bottom surface inside the medicine guide hopper 315, a docking ring 332 disposed at the bottom opening of the rotating nozzle 331, a rotating fan blade 333 that rotates as airflow passes through, and a scraper 334 used to clean the droplets on the inner wall of the fixed cup body 311.

[0062] Specifically, the bottom of the rotating nozzle 331 is rotatably connected to the inner side of the rotating groove 3150. The rotating nozzle 331 has an air jet 3310 that runs vertically through it. The docking ring 332 is fixed to the inner wall of the air jet 3310 by a protrusion on the outer side wall. The rotating fan blade 333 is integrally formed with the docking ring 332. One end of the scraper 334 is fixed to the outer side wall of the rotating nozzle 331, and the other end abuts against the inner wall of the fixed cup body 311.

[0063] Furthermore, the airflow in the inner tube 322 will directly enter the inner side of the docking ring 332, and by rotating the fan blade 333, the docking ring 332 and the rotating nozzle 331 will rotate, which will also cause the scraper 334 to rotate.

[0064] In this embodiment, as Figures 8-11 As shown, the airflow blocking mechanism 340 includes an inner tube body 341, a docking nozzle body 342 disposed below the inner tube body 341, a limiting clamp 343 that restricts the rotation range of the docking nozzle body 342, two sets of transmission parts 344 disposed inside the limiting clamp 343, a prying part 345 that moves with the movement of the internal structure of the transmission part 344, and a blocking part 346 that moves repeatedly with the movement of the prying part 345.

[0065] Specifically, the inner tube body 341 is snapped and fixed at the top opening of the fixed cup body 311, two limiting clamps 343 are snapped and fixed on the bottom surface of the inner tube body 341 and have a connecting groove 3430 inside for providing a placement area for the internal structure of the airflow blocking mechanism 340, the connecting nozzle body 342 is rotatably connected between the two limiting clamps 343, the connecting nozzle body 342 has several vertically penetrating suction grooves 3420 inside, and an external protrusion 3421 is integrally formed on the outer side wall of the connecting nozzle body 342.

[0066] Furthermore, the inner tube 341 is used to allow external airflow to enter the interior of the fixed cup 311. During the rotation of the crossbar at the bottom of the scraper 334, it will simultaneously drive the docking nozzle 342 to rotate. At this time, the continuously flowing airflow will draw the medicine in the medicine guide hopper 315 upward from the medicine suction groove 3420 in the docking nozzle 342.

[0067] In this embodiment, as Figure 12 As shown, the transmission unit 344 includes a movable frame 3440 that moves with the rotation of the docking nozzle body 342, a pressure spring 3441 disposed on the inner frame wall of the movable frame 3440, and a fixed toothed plate 3445 that moves up and down with the movement of the movable frame 3440.

[0068] Specifically, the movable frame 3440 is slidably connected to the inside of the connecting groove 3430. The elastic force provided by the pressure spring 3441 is used to push the movable frame 3440 to move towards the docking nozzle 342. A guide bracket 3442 is snapped onto the top surface of the movable frame 3440. The fixed tooth plate 3445 is fixed to the movable rod 3443, which is slidably connected to the top wall of the connecting groove 3430. The bottom end of the movable rod 3443 is integrally formed with an upward block 3444 that abuts against the top surface of the guide bracket 3442.

[0069] Furthermore, as the docking nozzle 342 rotates, the outer protrusion 3421 will abut against the movable frame 3440. In conjunction with the pressure spring 3441, the movable frame 3440 will reciprocate within the connecting groove 3430, thereby driving the guide bracket 3442 to move together. This will cause the position of the lifting block 3444 to change continuously, and the position of the fixed toothed plate 3445 will move up and down through the moving rod 3443.

[0070] In this embodiment, as Figure 13 As shown, the actuating part 345 includes a rod gear 3452 that rotates as the fixed tooth plate 3445 moves, a mating gear 3453 that meshes with the rod gear 3452, and an actuating rod 3455 that rotates as the mating gear 3453 rotates.

[0071] Specifically, the actuating part 345 also includes a fixing strip 3450 that is snapped and fixed to the top surface of the two limiting clamps 343. The fixing strip 3450 has a placement groove at both ends for providing a rotation range for the lever gear 3452. The lever gear 3452 has a rotating rod 3451 inside it, and the lever gear 3452 meshes with the fixed tooth plate 3445.

[0072] Furthermore, a dial 3454 is provided above the rotating rod 3451, and the central rod of the dial 3454 is rotatably connected to the groove wall of the mounting slot of the fixing strip 3450. The mating gear 3453 is sleeved on the outside of the central rod of the dial 3454, and the two ends of the actuating rod 3455 are snapped and fixed between the two dials 3454.

[0073] Furthermore, the fixing bar 3450 is used to ensure the stability of the overall structure of the actuating part 345, and the rotating rod 3451 is used to provide a placement area for the rod gear 3452. The up-and-down moving fixing tooth plate 3445 will drive the rod gear 3452 to rotate, which will drive the mating gear 3453 to rotate faster, thereby driving the dial 3454 together with the actuating rod 3455 to rotate, thereby driving the entire blocking part 346 to rotate.

[0074] In this invention, the blocking part 346 includes an airflow baffle 3460 slidably connected to the bottom of the fixing bar 3450, a limiting slider 3461 integrally formed above the airflow baffle 3460, and a plurality of blocking racks 3462 regularly distributed on the bottom surface of the airflow baffle 3460. The airflow baffle 3460 has a through groove inside for providing a moving range for the toggle lever 3455.

[0075] Furthermore, the limiting slider 3461 on the airflow baffle 3460 is used to limit the movement range of the airflow baffle 3460, and the blocking rack 3462 increases the contact area between the bottom of the airflow baffle 3460 and the airflow, thereby increasing the atomization effect of the agent.

[0076] A mechanically pressurized nebulizer method suitable for respiratory medicine, employing the aforementioned mechanically pressurized nebulizer device suitable for respiratory medicine, includes the following steps:

[0077] S1. First, pour the medicine into the inside of the fixed cup 311, and then insert the inner tube 341 into the top opening of the fixed cup 311.

[0078] S2. Next, connect the two ends of the ventilation hose 200 to the air outlet of the air compressor 100 and the bottom of the connecting pipe 320, respectively, and turn on the air compressor 100 to send the compressed airflow into the interior of the connecting pipe 320.

[0079] S3. After the airflow passes through the bottom of the connecting pipe 320, it will be divided into two streams by several regularly distributed guide vanes 323, which will flow upward from the outer air pipe 321 and the inner pipe 322 respectively.

[0080] S4. Subsequently, the airflow in the inner tube 322 will directly enter the inner side of the docking ring 332. By rotating the fan blade 333, the docking ring 332 and the rotating nozzle 331 will rotate, which will also drive the scraper 334 to rotate. During the rotation of the crossbar at the bottom of the scraper 334, the docking nozzle body 342 will rotate at the same time.

[0081] S5. As the docking mouth body 342 rotates, the outer protrusion 3421 will abut against the moving frame 3440. With the help of the pressure spring 3441, the moving frame 3440 will reciprocate inside the connecting groove 3430, and the position of the fixed tooth plate 3445 will move up and down.

[0082] S6. After that, the fixed toothed plate 3445, which moves up and down, will drive the rod gear 3452 to rotate, which will drive the mating gear 3453 to rotate faster, and then drive the dial 3454 together with the lever 3455 to rotate, thereby driving the entire blocking part 346 to rotate.

[0083] S7. At this time, the continuously flowing airflow will draw the medicine in the medicine guide 315 upward from the medicine suction groove 3420 in the mouthpiece 342 and hit the blocking part 346. The medicine will be atomized. The user can inhale the generated mist into the lungs by covering the mouthpiece 312 with his mouth.

[0084] S8. Subsequently, the drug droplets condensed on the inner wall of the fixed cup 311 will also continuously flow back into the interior of the drug guide hopper 315 under the action of the scraper 334.

[0085] The foregoing description of specific exemplary embodiments of the invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
