Abstract
Description
Technical Field
[0001] This invention relates to the field of drug delivery systems, and particularly to a respiratory drug delivery system for use in respiratory medicine. Background Technology
[0002] In the treatment of respiratory diseases, inhaled drug delivery, as a treatment method that directly targets the lesion, is widely used in the treatment of respiratory diseases such as asthma and chronic obstructive pulmonary disease due to its rapid onset of action and high drug utilization rate. Currently, common inhaled drug delivery devices mainly include metered-dose inhalers and nebulizers. However, existing respiratory drug delivery systems have many limitations in use. On the one hand, when multiple drugs need to be used simultaneously for combined treatment, traditional devices struggle to achieve uniform mixing of the drugs, leading to uneven drug deposition in the lungs and affecting treatment efficacy. On the other hand, existing drug delivery systems lack quantitative drug dispensing capabilities, requiring medical personnel to prepare the medication before use. This process is cumbersome and prone to contamination, thus reducing the effectiveness and safety of treatment.
[0003] For the reasons mentioned above, this invention proposes a respiratory drug delivery system for respiratory medicine, which can achieve uniform and convenient drug delivery based on a breathing mask, thereby improving the effectiveness and convenience of respiratory drug delivery. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A respiratory drug delivery system for respiratory medicine includes a housing. A circular shell is fixedly connected to the front sidewall of the housing. An air inlet pipe is fixedly connected to the center of the front sidewall of the circular shell. A main shaft is installed inside the air inlet pipe. Several paddle blades and fan blades are respectively installed at both ends of the main shaft. Several drug cartridges are evenly distributed and fixedly connected to the sidewall of the circular shell. An atomizing nozzle is installed on one side of the inner cavity of the drug cartridge, and a first piston is provided in the inner cavity of the drug cartridge. A vertical rod penetrating the drug cartridge is fixedly connected to the first piston. A drug inlet pipe is fixedly connected to the sidewall of the inner cavity of the circular shell, and a fixed feeding pipe is fixedly connected to the sidewall of the outer cavity of the drug cartridge. A one-way component is provided in both the drug inlet pipe and the fixed pipe. A vertical pipe is fixedly connected to the fixed pipe.

[0007] Preferably, a side plate and a baffle are fixedly connected to both ends of the crossbar, and a first spring is sleeved on the crossbar, with both ends of the first spring fixedly connected to the side plate and the crossbar, respectively.
[0008] Preferably, the pressurizing assembly includes a movable rod, which is movably connected to the side wall of one end of the vertical tube located in the inner cavity of the circular shell. A second piston is fixedly connected to one end of the movable rod located in the inner cavity of the vertical tube, and a second spring is sleeved on the movable rod.
[0009] Preferably, the two ends of the second spring are fixedly connected to the vertical tube and the second piston, respectively. The main shaft is fixedly connected to a number of fixed rods on the outer wall of the same cross section as the movable rod. Arc-shaped plates are fixedly connected to both the movable rod and the fixed rods.
[0010] Preferably, an airbag is fixedly connected to the side of the cover away from the circular shell, and two straps are fixedly connected to the outer side wall of the cover.
[0011] Preferably, a scale is fixedly connected to the side wall of the vertical rod, and a flat plate is fixedly connected to the end of the vertical rod away from the first piston.
[0012] Preferably, sealing rings are fixedly connected to the side walls of both the first piston and the second piston, the diameter of the baffle is larger than the inner diameter of the fixing ring, and another sealing ring is fixedly connected to the side wall of the baffle near the fixing ring.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: This invention uses a paddle to drive the main shaft to rotate, which in turn drives a fixed rod and fan blades to rotate. The fixed rod drives an arc-shaped plate to rotate, causing the arc-shaped plate on the fixed rod to push the arc-shaped plate on the movable rod to move. The movable rod drives the second piston to move inside the vertical tube, increasing the air pressure inside the vertical tube. Under the action of the one-way component, the air pressure on one side of the medicine shell increases. As the main shaft continues to rotate, the air pressure on one side of the medicine shell continues to increase. The air pressure pushes the first piston, which in turn pushes the medicine in the medicine shell, causing the medicine to be atomized and sprayed from the atomizing nozzle into the inner cavity of the circular shell. This allows multiple medicines to be added into the circular shell. Through the rotation of the fan blades and the fixed rod, the mixing of multiple medicines can be achieved, resulting in uniform drug delivery. This invention involves pulling a flat plate, which in turn moves a vertical rod. The vertical rod then moves a first piston within the medicine container, reducing the air pressure on one side of the container. At this point, the medicine is drawn into the container through the inlet tube. The amount of medicine dispensed can be controlled using a scale on the vertical rod, reducing contamination of the medicine during cumbersome operations and facilitating the dispensing process.

Detailed Implementation
[0020] The respiratory drug delivery system for respiratory medicine provided by the present invention 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 well-known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.
[0021] like Figure 1-9 As shown, an embodiment of the present invention provides a respiratory drug delivery system for respiratory medicine, including a cover 1. An air bag 27 is fixedly connected to the side of the cover 1 away from the round shell 2. Two straps 28 are fixedly connected to the outer side wall of the cover 1. When in use, the cover 1 is placed on the patient's nose, and the straps 28 are used to fix the cover 1 to the patient, which is convenient to use. The air bag 27 can improve the comfort of use. A circular shell 2 is fixedly connected to the front side wall of the cover 1. An air inlet pipe 3 is fixedly connected to the center of the front side wall of the circular shell 2. A main shaft 4 is installed inside the air inlet pipe 3. Several blades 5 and fan blades 6 are installed at both ends of the main shaft 4. A bracket 34 is fixedly connected to the side wall of the main shaft 4. The bracket 34 is Y-shaped and fixedly connected to the inner wall of the air inlet pipe 3. In the technical solution of this embodiment, the external oxygen supply device is activated, so that oxygen is delivered to the inner cavity of the round shell 2 and the cover 1 through the air inlet pipe 3. Under the push of oxygen, the paddle 5 can rotate, the paddle 5 drives the main shaft 4 to rotate, the main shaft 4 drives the fixed rod 25 and the fan blade 6 to rotate. The rotation of the fixed rod 25 can realize the drug delivery drive operation, and the rotation of the fan blade 6 can realize the mixing and blowing of the drug, which is convenient for drug delivery. A circular plate 32 is fixedly connected to the side wall of the circular shell 2 near the cover 1. The circular plate 32 is circular and has several through holes 33, which can realize the separation between the fan blade 6 and the inner cavity of the cover 1 and ensure the passage of the medicine. This not only facilitates drug administration but also avoids the influence of the fan blade 6 on the patient, resulting in good efficacy. A number of medicine shells 7 are evenly distributed and fixedly connected on the side wall of the circular shell 2. An atomizing nozzle 8 is installed on one side of the inner cavity of the medicine shell 7. A first piston 9 is provided in the inner cavity of the medicine shell 7. A vertical rod 10 that penetrates the medicine shell 7 is fixedly connected to the first piston 9. A scale 29 is fixedly connected to the side wall of the vertical rod 10. A flat plate 30 is fixedly connected to the end of the vertical rod 10 away from the first piston 9. In the technical solution of this embodiment, before use, the medicine bottles are inserted into the inlet tube 11. Then, the medical staff pulls the plate 30 according to the dosage of the medicine. The plate 30 drives the vertical rod 10 to move. The vertical rod 10 drives the first piston 9 to move in the inner cavity of the medicine shell 7, so that the air pressure on one side of the inner cavity of the medicine shell 7 decreases. At this time, the medicine is drawn into the medicine shell 7 through the inlet tube 11. The scale 29 on the vertical rod 10 can be used to control the dosage of the medicine, which facilitates the medicine dispensing operation. A medicine shell 7 is fixedly connected to a medicine inlet pipe 11 on the side wall of the inner cavity of the circular shell 2, and a fixed feeding pipe 12 is fixedly connected to the side wall of the outer cavity of the circular shell 2. A vertical pipe 14 is fixedly connected to the fixed pipe 12. The vertical pipe 14 penetrates the circular shell 2 and a pressure assembly 15 is provided in the inner cavity. The pressure assembly 15 includes a movable rod 22. The movable rod 22 is movably connected to the side wall of one end of the inner cavity of the circular shell 2. A second piston 23 is fixedly connected to one end of the movable rod 22 in the inner cavity of the vertical pipe 14. A second spring 24 is sleeved on the movable rod 22. The two ends of the second spring 24 are fixedly connected to the vertical pipe 14 and the second piston 23, respectively. A number of fixed rods 25 are fixedly connected to the outer wall of the same cross section of the movable rod 22. An arc plate 26 is fixedly connected to both the movable rod 22 and the fixed rods 25. In this embodiment, the propeller 5 rotates under the influence of oxygen, which in turn drives the main shaft 4 to rotate. The main shaft 4 then drives the fixed rod 25 and the fan blade 6 to rotate. The fixed rod 25 drives the arc plate 26 to rotate, causing the arc plate 26 on the fixed rod 25 to push the arc plate 26 on the movable rod 22 to move. The movable rod 22 drives the second piston 24 to move inside the vertical tube 14, increasing the air pressure inside the vertical tube 14. Under the action of the air pressure, the baffle 20 on the side of the fixed tube 12 near the drug shell 7 moves. The baffle 20 drives the crossbar 18 to move, and the crossbar 18 drives the side plate 19 to move. The side plate 19 stretches the first spring 21, allowing gas to enter the drug shell 7 from between the baffle 20 and the fixed ring 16. When the fixed rod 25 and the arc plate 26 on the movable rod 22 cross each other, the first spring 21 then... The baffle 20 and the fixed ring 16 are brought together, and the second piston 23 moves in the opposite direction under the elastic force of the first spring 21. At this time, under the action of air pressure, the one-way component 13 on the side of the fixed tube 12 away from the medicine shell 7 is opened, and external air is injected into the cavity of the fixed tube 12 and the vertical tube 14. When the second piston 23 is reset, the one-way components 13 at both ends of the fixed tube 12 are closed, completing one pressurization operation of the cavity of the medicine shell 7. As the main shaft 4 continues to rotate, the air pressure on one side of the medicine shell 7 can be continuously increased. The air pressure pushes the first piston 9, and the first piston 9 pushes the medicine in the medicine shell 7, so that the medicine is atomized and sprayed from the atomizing nozzle 8 into the cavity of the round shell 2, so that multiple medicines are added into the round shell 2, which can realize the mixing operation of multiple medicines and improve the uniformity of the medicine. Both the drug inlet tube 11 and the fixed tube 12 are provided with a one-way component 13. The one-way component 13 includes a fixed ring 16. The fixed ring 16 is fixedly connected to both ends of the inner cavity of the fixed tube 12. Another fixed ring 16 is fixedly connected to the inner cavity of the drug inlet tube 11. A horizontal plate 17 is fixedly connected to the inner side wall of the fixed ring 16. A horizontal bar 18 is movably connected to the center of the horizontal plate 17. The two ends of the horizontal bar 18 are fixedly connected to a side plate 19 and a baffle 20, respectively. A first spring 21 is sleeved on the horizontal bar 18. The two ends of the first spring 21 are fixedly connected to the side plate 19 and the horizontal plate 17, respectively. In the technical solution of this embodiment, under the action of air pressure, the baffle 20 and the fixed tube 16 can be separated, thereby realizing the passage of the internal channel, which facilitates the passage of gas and medicine. Under the elastic force of the first spring 21, the baffle 20 and the fixed tube 16 can be attached together to seal the internal channel, prevent the leakage of medicine, and facilitate use. Furthermore, sealing rings 31 are fixedly connected to the side walls of the first piston 9 and the second piston 23. The diameter of the baffle 20 is larger than the inner diameter of the fixing ring 16, and another sealing ring 31 is fixedly connected to the side wall of the baffle 20 near the fixing ring 16. This can effectively improve the sealing performance of the device and make it effective in use.
[0022] Working Principle: Before use, the medication bottles are inserted into the inlet tube 11. Medical personnel then pull the plate 30 according to the dosage. The plate 30 moves the vertical rod 10, which in turn moves the first piston 9 within the medication shell 7. This reduces the air pressure on one side of the medication shell 7, causing the baffle 20 inside the inlet tube 11 to separate from the fixing ring 16. The medication can then be drawn into the medication shell 7 through the inlet tube 11. The dosage can be controlled using the scale 29 on the vertical rod 10. After dispensing, the medication bottle is removed from the inlet tube 11.Simultaneously, under the action of the first spring 21, the baffle 20 and the fixing ring 16 are brought together, closing the drug inlet tube 11 and completing the convenient drug dispensing operation. In use, the oxygen delivery pipe is connected to the air inlet tube 3, and the cover 1 is placed on the patient's nose. The cover 1 is then fixed to the patient using the strap 28. The strap 28 allows the airbag 27 to fit snugly against the patient's skin, improving tightness and comfort. Then, the external oxygen supply device is activated, allowing oxygen to be delivered through the air inlet tube 3 into the inner cavity of the round shell 2 and the cover 1. Driven by the oxygen, the paddle 5 rotates, and the paddle 5 drives... The main shaft 4 rotates, driving the fixed rod 25 and the fan blade 6 to rotate. The fixed rod 25 drives the arc plate 26 to rotate, causing the arc plate 26 on the fixed rod 25 to push the arc plate 26 on the movable rod 22 to move. The movable rod 22 drives the second piston 24 to move inside the vertical tube 14, increasing the air pressure inside the vertical tube 14. Under the action of air pressure, the baffle 20 on the side of the fixed tube 12 near the medicine shell 7 moves. The baffle 20 drives the horizontal rod 18 to move, and the horizontal rod 18 drives the side plate 19 to move. The side plate 19 stretches the first spring 21, allowing gas to enter the medicine shell 7 from between the baffle 20 and the fixed ring 16. When the fixed ring 20 is in place, the gas is released into the cavity of the medicine shell 7. After the fixed rod 25 and the arc-shaped plate 26 on the movable rod 22 cross, the baffle 20 and the fixed ring 16 are brought together by the action of the first spring 21. The second piston 23 moves in the opposite direction under the elastic force of the first spring 21. At this time, the one-way component 13 on the side of the fixed tube 12 away from the medicine shell 7 opens under the action of air pressure, injecting external air into the inner cavity of the fixed tube 12 and the vertical tube 14. When the second piston 23 returns to its original position, the one-way components 13 at both ends of the fixed tube 12 close, completing one pressurization operation on the inner cavity of the medicine shell 7. With the continuous rotation of the main shaft 4, the medicine... The air pressure on one side of shell 7 continuously increases, pushing the first piston 9. The first piston 9 pushes the medication in the medication shell 7, causing the medication to be atomized and sprayed from the atomizing nozzle 8 into the inner cavity of the circular shell 2. This allows multiple medications to be added into the circular shell 2. The rotation of the fan blade 6 and the fixed rod 25 enables the mixing of multiple medications, improving the uniformity of the medication. With the flow of oxygen and the blowing of the fan blade 6, the mixed medication is discharged through the through hole 33 into the inner cavity of the cover shell 1. Under the patient's breathing, the mixed medication is inhaled into the body, completing the uniform administration of multiple medications and improving the convenience of drug delivery.
