Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, in particular to a portable insulin atomization drug delivery device. Background Art
[0002] An insulin nebulizer is a portable device that converts insulin solution into a mist of fine particles for inhalation. It uses atomization technology to break down liquid insulin into fine particles, enabling rapid absorption through the lung capillaries, thereby replacing traditional subcutaneous injections. The device typically consists of a nebulizer, power supply, and drug storage unit. It is easy to use and suitable for diabetic patients who require frequent injections. While its advantages are painlessness and rapid absorption, it requires careful consideration of dosage control and potential impact on lung health. Currently still in the optimization phase and not yet fully adopted, it may become a key method of insulin delivery in the future.
[0003] Existing non-piston insulin atomization devices (such as ultrasonic, mesh, and jet types) generally have the problem of insufficient drug delivery control accuracy, and are unable to flexibly adjust the atomization rate and dosage according to individual needs, resulting in poor drug delivery uniformity; the mask and host connection structure is usually complex in design (such as multi-threaded screws or tiny buckles), and the disassembly and cleaning process is tedious and laborious, which easily leads to cleaning dead corners and residual drug solution, posing a high risk of microbial growth; at the same time, the liquid storage components often lack an effective insulation layer, and ambient temperature fluctuations directly affect the stability of the drug solution. In addition, the inner wall of the pipeline lacks anti-adsorption treatment, resulting in residual insulin, which together cause the defect of uncontrollable effective drug delivery concentration and affect the reliability of therapeutic efficacy. Summary of the Invention

When the pressure changes, the liquid medicine in the liquid storage tank 3 will be sucked into the cavity through the delivery pipe 18 and discharged through the nozzle in the mounting ring 2 6. The discharged liquid medicine will hit the diverter plate 19. Since the diverter plate 19 is set in a cone shape, under the action of the diverter plate 19, the liquid medicine is dispersed into smaller particles and absorbed by the patient, thereby achieving the effect of rapid drug administration. A Venturi acceleration ring (integrated into the interior of the mounting ring 2 6) is added between the nozzle outlet and the diverter plate 19 to accelerate the shearing of the liquid medicine through the throat; The right end of the applicator body 1 is penetrated by a mounting ring 2 6, the other end of the mounting ring 2 6 is correspondingly provided with a mounting ring 1 4, the other end of the mounting ring 1 4 is penetrated by a mask 5, the inner end of the mounting ring 2 6 is installed with a sealing sleeve 25, the inner end of the mounting ring 1 4 is installed with a sealing sleeve 1 23, the diameter of the sealing sleeve 25 is equal to the inner ring diameter of the sealing sleeve 1 23, the right end of the liquid storage tank 3 is penetrated by a delivery pipe 18, the other end of the delivery pipe 18 is penetrated and provided at the bottom of the applicator body 1, by providing the mounting ring 1 4 and the mounting ring 2 6, it is convenient for the user to disassemble the mask 5, and the socket design of the two sealing sleeves can ensure the sealing effect of the connection between the two to the greatest extent, and avoid leakage; The inner ends of the partition 32 are fixedly connected with sliding rods 8, and the movable plate 15 is slidably connected to the sliding rods 8. A spring 7 is sleeved on the sliding rod 8. One end of the spring 7 is fixedly connected to the inner end of the partition 32, and the other end is fixedly connected to the movable plate 15. The inside of the mask 5 is fixedly connected with a diverter plate 19. By setting the sliding rods 8 and the spring 7, the movable plate 15 can be restricted to ensure the stable sliding of the movable plate 15. At the same time, the movable plate 15 has an elastic buffer effect to avoid direct contact with the partition 32 and damage. The inner end of the mounting ring 26 is fixedly connected with three limit blocks 21, and the inner end of the mounting ring 1 4 is provided with three limit grooves 24. The limit blocks 21 correspond to the limit grooves 24. The outer end of the mounting ring 26 is rotatably connected with three rotating parts 22. The inner middle part of the limit block 21 is fixedly connected with a connecting shell 26. The rotating part 22 passes through the connecting shell 26 and is fixedly connected to a bevel gear 1 30 inwardly. The inner side of the connecting shell 26 is rotatably connected with a bidirectional screw 29. The middle part of the bidirectional screw 29 is fixedly connected with a bevel gear 2 31. The bevel gear 1 30 and the bevel gear 2 31 are meshed with each other. The upper thread of the bidirectional screw 29 is matched with two positioning blocks 28, and the positioning block 28 is set inside the limit block 21. The limit groove Limiting grooves 24 are provided at both ends of the inner side of 24, and the positioning blocks 28 correspond to the positioning grooves 20. The inner ends of the positioning blocks 28 are fixedly connected to the limiting plates 27. The mask needs to be disassembled, disinfected and cleaned. At this time, the three rotating parts 22 are rotated in sequence to drive the internal bevel gear 1 30 to rotate. Similarly, under the meshing action, the bevel gear 2 21 and the bidirectional screw 29 can be driven to rotate. The positioning blocks 28 at both ends can be gradually retracted toward the inside of the limiting blocks 27 through threaded cooperation, so that they are out of the inside of the positioning grooves 20. The user can directly pull the entire mask 5 outward to remove it from the applicator body 1, which is more convenient for replacing and cleaning it.
[0019] Working principle: When in use, the user matches the mask 5 with the face. When atomization medication is required, the start button on the side end of the medication device body 1 is activated, and the motor 14 receives the signal to rotate, driving the gear 2 13 to rotate, and can drive the gear 12 and the rotating shaft 11 to rotate under the meshing action. Under the action of the turntable 10 and the connecting rod 9, the movable plate 15, the support rod 16 and the piston plate 17 can be reciprocated to change the cavity pressure. When the pressure changes, the liquid medicine in the liquid storage tank 3 will be sucked into the cavity through the delivery pipe 18 and discharged through the nozzle in the mounting ring 2 6. The discharged liquid medicine will hit the diverter plate 19. Since the diverter plate 19 is conical, under the action of the diverter plate 19, the liquid medicine is dispersed into smaller particles and absorbed by the patient, thereby achieving the effect of rapid medication. After the nebulization is completed, the user disengages from the mask, and the mask needs to be disassembled, disinfected and cleaned. At this time, the three rotating parts 22 are rotated in sequence to drive the internal bevel gear 1 30 to rotate. Similarly, under the meshing action, the bevel gear 2 21 and the bidirectional screw 29 can be driven to rotate, and the positioning blocks 28 at both ends can be gradually retracted toward the inside of the limit block 27 through threaded cooperation, so that they are out of the inside of the positioning groove 20. The user can directly pull the entire mask 5 outward to remove it from the applicator body 1, which is more convenient for replacement and cleaning. In addition, the entire device is designed to be small in size, which is convenient for users to operate with both hands, thereby improving its convenience.
