[0042] In order to enable those skilled in the technical field to better understand the technical solutions in this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments.

[0043] The embodiments of this application provide a respiratory atomization drug delivery device.

[0044] Embodiment 1, as Figures 1-9 shown.

[0045] A respiratory atomization drug delivery device includes a main body box 1, and an installation groove 11 is provided at the lower part of the rear side of the main body box 1;

[0046] A respiratory atomization drug delivery device includes a medicine storage box 2, which is installed in the installation groove 11. Each medicine storage box 2 stores one kind of medicine. A number of the medicine storage boxes 2 are sequentially installed in the installation groove 11 so as to atomize a variety of medicines. A number of inner grooves 12 are provided at the top of the installation groove 11. A protrusion 21 is provided at the top of the medicine storage box 2, and the protrusion 21 is adapted to the inner groove 12. Each medicine storage box 2 is connected to the main body box 1 by engaging the protrusion 21 into the inner groove 12.

[0047] A respiratory atomization drug delivery device includes a mixing component 3 installed inside the main body box 1, which mixes multiple drugs to meet the subsequent atomization requirements.

[0048] A partition plate 13 is arranged at the upper part of the inner cavity of the main body box 1. The space surrounded by the partition plate 13 and the upper part of the main body box 1 is a transmission cavity 15. An intermediate plate 14 is arranged at the lower part of the inner cavity of the main body box 1. The intermediate plate 14 divides the lower inner cavity of the main body box 1 into an atomization cavity 17 and a mixing cavity 16. Multiple drugs are mixed in the mixing cavity 16, and the mixed drugs are atomized in the atomization cavity 17.

[0049] Several delivery pumps 151 are installed inside the transmission cavity 15. Each delivery pump 151 corresponds to one of the inner grooves 12. A connecting pipe is arranged in the inner groove 12, and the connecting pipe is inserted into the bottom of the inner cavity of the corresponding medicine storage box 2. A spraying plate is installed on the top surface of the mixing cavity 16. The input end of the delivery pump 151 is communicated with the corresponding inner groove 12 through a pipeline, and the output end of the delivery pump 151 is communicated with the spraying plate through a pipeline. The delivery pump 151 pumps the liquid medicine in the medicine storage box 2 to the spraying plate, and then sprays it into the mixing cavity 16 through the spraying plate.

[0050] The mixing component 3 includes a bracket 31, a motor 32, a gear 33, a rack 34, a moving block 35, a mixing shaft 36, mixing rods 37, and a derivation pump 38. The bracket 31 is installed on the bottom surface of the transmission cavity 15. The motor 32 is installed at the bottom of the bracket 31, and the bottom of the motor 32 is slidably connected to the bracket 31. A gear 33 is installed on the output shaft of the motor 32. A moving groove is formed through the side wall of the top surface of the mixing cavity 16. A rack 34 is installed on the bottom surface of the transmission cavity 15 outside the moving groove. The rack 34 is in meshing transmission with the gear 33. A moving block 35 is slidably connected in the moving groove. A mixing shaft 36 is rotatably connected through the middle of the moving block 35. Several groups of mixing rods 37 are arranged on the mixing shaft 36. The top of the mixing shaft 36 is fixedly connected to the bottom of the output shaft of the motor 32. A derivation pump 38 is installed on the side wall of the atomization cavity 17. The input end of the derivation pump 38 is communicated with the bottom of the mixing cavity 16 through a pipeline, and the output end of the derivation pump 38 is communicated with the bottom of the atomization cavity 17 through a pipeline.

[0051] When mixing the medicine, the motor 32 starts. Through the meshing of the gear 33 and the rack 34, and the sliding connection of the moving block 35 and the moving groove, the motor 32 and the moving block 35 move along the moving groove. At the same time, during the movement of the motor 32, the mixing shaft 36 connected thereto rotates and moves, that is, the mixing shaft 36 can rotate by itself and can also change its position driven by the motor 32. Then, through the mixing rod 37, the liquid medicine in the mixing chamber 16 is stirred and mixed to make it evenly mixed.

[0052] A respiratory atomization drug delivery device includes an atomization assembly 4 installed inside the main body box 1 to atomize the liquid medicine.

[0053] The atomization assembly 4 includes an atomization sheet 41, an upper collision plate 42, a lower collision plate 43, a lead-out pipe 44, and a mesh plate 45. The atomization sheet 41 is installed on the bottom surface of the atomization chamber 17. When the atomization sheet 41 is powered on, the liquid medicine can be atomized. An inspection door is provided on the side wall of the atomization chamber 17. After the device is used for a period of time, the atomization sheet 41 can be replaced through the inspection door.

[0054] The upper collision plate 42 and the lower collision plate 43 are sequentially installed obliquely in the upper part of the atomization chamber 17. Both the upper collision plate and the lower collision plate 43 are of a mesh structure. The atomized liquid medicine passes through the upper collision plate 42 and the lower collision plate 43 and is broken by collision.

[0055] The lead-out pipe 44 is installed in the upper part of the atomization chamber 17, and the mesh plate 45 is provided at the end of the lead-out pipe 44. On the one hand, the mesh plate 45 can break the atomized liquid medicine again, and on the other hand, it can slow down the flow rate of the atomized gas, thereby reducing the stimulation to the patient's breathing.

[0056] Both the upper collision plate 42 and the lower collision plate 43 are wavy. The upper collision plate 42 and the lower collision plate 43 are inclined in opposite directions.

[0057] The design of the wavy shape: 1. makes the movement path of the liquid medicine particles longer in the wavy collision plate, increasing the contact opportunity with the collision plate. 2. The wavy structure disperses the impact force of the particles in multiple directions, avoiding the particle rebound caused by collision at a single angle.

[0058] Inclined installation design: 1. Change the incident angle of the atomized particles so that the atomized particles do not collide vertically. The inclined installation makes the atomized particles impact the collision plate at a certain angle (such as 30°-60°), increasing the shear force component and improving the crushing efficiency. At the same time, it can also reduce the rebound and escape. The inclined angle can guide the particles after collision to move in a specific direction, avoiding directly escaping from the atomization chamber 17 after rebound. 2. It can reduce the turbulent resistance. The inclined angle reduces the frontal impact of the air flow on the collision plate, reducing energy loss and noise.

[0059] The combination of the wavy shape and the inclined installation: The inclined installation enhances the shear force (the component force parallel to the collision plate), and the wavy structure enhances the normal force (the component force perpendicular to the collision plate). The combination of the two forces breaks the particles more efficiently, making the broken particles more uniform and the crushing efficiency higher.

[0060] The atomization component 4 further includes a pressing airbag 46 and an air inlet pipe 47. The pressing airbags 46 are arranged on both sides of the main body box 1. One side of the pressing airbag 46 is connected with the air inlet pipe 47, and a one-way valve is installed at the end of the air inlet pipe 47. By pressing the airbag, high-speed air flow can be introduced into the atomization chamber 17 to make the particle size of the drug particles smaller.

[0061] The atomization component 4 further includes a pressure pump 48. The pressure pump 48 is installed on one side of the main body box 1. The output end of the pressure pump 48 is communicated with the lower part of the atomization chamber 17 through a pipeline. Through the pressure pump 48, the air flow rate in the atomization chamber 17 can be further increased, and the output gas flow rate of the pressure pump 48 is variable. According to the different sizes of the atomized particles of different drugs, the pressure pump 48 inputs air with different flow rates. The greater the input flow rate of the air, the stronger the crushing degree of the particles.

[0062] During use, according to different usage requirements, the pressing airbag 46 can be pressed or the pressure pump 48 can be started to introduce air flow into the atomization chamber 17 to crush the atomized particles.

[0063] A mask assembly 5 is installed at the outer end of the outlet pipe 44, which fits with the patient's face for respiratory treatment.

[0064] The mask assembly 5 includes an atomization mask 51 and a fitting strip 52. The atomization mask 51 is installed at the outer end of the outlet pipe 44, and the fitting strip 52 is arranged at the edge of the atomization mask 51. The fitting strip 52 is a flexible structure and can be squeezed according to the position of the patient's face so that the atomization mask 51 can better fit the patient's face.

[0065] A diversion assembly 6 is arranged at the connection between the mask assembly 5 and the outlet pipe 44, and the diversion assembly 6 is located inside the mask assembly 5 to adapt to different breathing modes of the patient, such as mouth breathing or nasal breathing.

[0066] The diversion assembly 6 includes a diversion tube 61, a diversion plate 62, a fixed electromagnet 63, and a movable electromagnet 64. The diversion tube 61 is arranged inside the atomization mask 51. The diversion tube 61 faces the connection between the atomization mask 51 and the outlet tube 44. The middle of the diversion plate 62 is rotatably connected to the front end of the diversion tube 61. Half of the diversion plate 62 is located inside the diversion tube 61, and half is located outside the diversion tube 61. The movable electromagnet 64 is arranged at the rear end of the diversion plate 62. The fixed electromagnets 63 are respectively arranged on the upper and lower sides of the inner cavity of the diversion tube 61. When the fixed electromagnets 63 and the movable electromagnet 64 are energized, they attract each other.

[0067] When the movable electromagnet 64 attracts the upper fixed electromagnet 63, the liquid medicine particles flow to the oral cavity of the patient to adapt to the patient's use of the mouth for breathing treatment.

[0068] When the movable electromagnet 64 attracts the lower fixed electromagnet 63, the liquid medicine particles flow to the nasal cavity of the patient to adapt to the patient's use of the nose for breathing treatment.

[0069] When the present invention is in use:

[0070] The patient wears the breathing mask and adjusts the position of the diversion plate 62 according to different breathing methods, mouth breathing or nose breathing. When the movable electromagnet 64 attracts the upper fixed electromagnet 63, the liquid medicine particles flow to the oral cavity of the patient to adapt to the patient's use of the mouth for breathing treatment; when the movable electromagnet 64 attracts the lower fixed electromagnet 63, the liquid medicine particles flow to the nasal cavity of the patient to adapt to the patient's use of the nose for breathing treatment.

[0071] Then, the medicine storage box 2 filled with liquid medicine is installed in the installation groove 11 at the rear side of the main body box 1. Then, through the mixing assembly 3, various liquid medicines are transported to the mixing chamber 16 for mixing. The mixed liquid medicine is pumped into the atomization chamber 17 by the outlet pump 38, and the liquid medicine is atomized by the atomization assembly 4, and the atomized particles are broken. The atomized liquid medicine follows the air flow into the outlet tube 44, enters the inside of the diversion assembly 6, and flows to the designated mouth and nose positions to facilitate the patient's breathing treatment.
