Description

Technical Field

[0001] The invention belongs to the technical field of atomizers, and in particular relates to an atomization drug delivery device used in airways. Background Art

[0002] Intra-airway atomization drug delivery devices are mainly used to atomize drug liquid into tiny particles. The drug particles enter the respiratory tract and are deposited in the lungs by inhalation, thereby achieving the purpose of rapid and effective treatment. Intra-airway atomization drug delivery devices are widely used in many medical fields such as internal medicine, surgery, and pediatrics, especially in the treatment of upper and lower respiratory system diseases. The intra-airway atomization drug delivery device needs to be cleaned internally after use to ensure its normal operation and extend its service life.

[0003] Existing publication number CN117298390A discloses an intra-airway atomization drug delivery device, including a chassis, a cover, a disposable catheter, a control panel, an atomization box, an anti-falling mechanism, an ultrasonic oscillator, a liquid level sensor, a self-cleaning mechanism, a fan and an electric heating wire. The device sprays high-pressure water through multiple nozzles to clean the inner wall of the atomization box. At the same time, the first gear and the second gear are driven to rotate by the second motor, and the shunt pipe and the nozzle are driven to rotate by the second gear, so that the inner wall of the atomization box is flushed more fully.

[0004] The existing device also has the following deficiencies:

[0005] 1. The spray direction of the nozzle of the existing device is fixed, and the position where the high-pressure water sprayed from the nozzle is sprayed onto the inner wall of the atomization box is fixed. When the position where the medicine liquid or medicine residue sticks to the atomization box does not coincide with the position where the nozzle is sprayed, it is difficult for the sprayed high-pressure water to clean the medicine liquid or medicine residue. The medicine residue or medicine liquid remaining on the inner wall of the atomization box will corrode the atomization box and reduce the service life of the device. In addition, during the next atomization treatment, the medicine residue and medicine liquid remaining in the atomization box will be mixed into the new medicine liquid, affecting the treatment effect.

[0006] 2. When cleaning the atomizer box, it is usually necessary to first use a disinfectant to disinfect the inside of the atomizer box, and then use pure water to clean the inside of the atomizer box to ensure that the atomizer box is clean. The existing device requires manual operation to replace the cleaning liquid during cleaning, which is cumbersome and has low work efficiency.

[0007] 3. The existing device supplies water through a high-pressure water pump during cleaning. The high-pressure water pump supplies water continuously. Some of the drug residues remaining in the atomization box will be washed to the top of the water flow by the high-pressure water flow and continue to be affected by the impact of the water flow and cannot flow to the bottom of the atomization box. After the flushing is completed, the drug residues still remain in the atomization box, resulting in incomplete cleaning. Summary of the invention

[0008] The purpose of the present invention is to provide an intra-airway atomization drug delivery device in view of the problems raised in the above background technology.

[0009] To achieve the above object, the present invention adopts the following technical scheme: a device for intra-airway atomization drug delivery, comprising:

[0016] Furthermore, the liquid separation unit includes a first rotating shaft rotatably connected to the center of the box body, the first rotating shaft passes through the top plate of the box body, the first rotating shaft and the central axis are connected through a reducer, a liquid separation plate is fixed on the first rotating shaft, the liquid separation plate is sealed and slidably connected to the side wall of the box body and the bottom plate of the box body, the height of the liquid separation plate is higher than the height of the first water inlet and the second water inlet, and a stirring element is provided on one side of the liquid separation plate.

[0017] Furthermore, the stirring element includes two mounting plates fixed on the first rotating shaft, the two mounting plates are rotatably connected to the second rotating shaft, the second rotating shaft is fixed with spiral blades, the top end of the second rotating shaft is fixed with a third column gear, and the top plate of the box body is fixed with an inner gear ring meshing with the third column gear.

[0018] Furthermore, the water supply component includes a sliding rod fixed in the function box, the sliding rod is sealed and slidably connected with a piston plate, the reciprocating screw passes through the piston plate and is threadedly connected to the piston plate, and a drainage pipe is provided between the box body and the function box.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. The present invention is provided with a spraying component. The water or disinfectant in the water tank is squeezed into the second water pipe through the water supply component and then flows along the second water pipe. Finally, the water or disinfectant enters the nozzle and is sprayed out. When the water or disinfectant flows along the second water pipe, it impacts the impeller to drive the impeller to rotate. The impeller drives the rotating rod and the nozzle to rotate, thereby expanding the spray range of the nozzle and improving the cleaning effect, thereby avoiding drug residues or drug liquid remaining in the atomization box, improving the service life of the device, and ensuring the treatment effect.

[0021] 2. The present invention sets a liquid separation unit. When cleaning is performed, the motor drives the reciprocating screw to rotate, thereby driving the water supply component to transport the disinfectant in the box to the second water pipe to disinfect the atomizer box. The reciprocating screw drives the second water pipe to rotate, thereby driving the first rotating shaft and the liquid separation plate to rotate slowly under the action of the reducer. The disinfectant in the box gradually moves away from the drainage pipe, while the pure water in the box gradually approaches the drainage pipe. Finally, the pure water enters the second water pipe through the drainage pipe to clean the atomizer box. There is no need for manual operation to replace the cleaning liquid. The operation is simple and the work efficiency is high.

[0022] 3. The present invention sets a stirring element. When the first rotating shaft rotates, it drives the mounting plate and the second rotating shaft to rotate around the first rotating shaft. Under the action of the third column gear and the inner gear ring, the second rotating shaft drives the spiral blade to rotate to stir the disinfectant, thereby avoiding stratification of the disinfectant due to long-term standing time, thereby ensuring the disinfection effect of the disinfectant.

[0023] 4. The present invention arranges a water supply component. When the reciprocating screw rotates, it drives the piston plate to move back and forth up and down in the function box. When the piston plate moves upward, the pressure in the function box decreases, and the water or disinfectant in the box enters the function box. When the piston plate moves downward, the water in the function box is squeezed into the first water pipe. Through the pulse water supply method, the medicine residue is washed away from the inner wall of the atomization box when the nozzle sprays water. When the nozzle stops spraying water, the medicine residue follows the water flow to the bottom of the atomization box, thereby avoiding that the nozzle continues to spray water and causing part of the medicine residue to fail to flow to the bottom of the atomization box, thereby improving the cleaning effect.

[0035] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0036] like Figure 1-Figure 6 As shown, a device for intra-airway atomization drug delivery comprises:

[0037] The nebulizer box 1 has a medicine inlet 11, a hose interface 12 and a drain port 13 on its side wall.

The rotating rod 25 extends into the second water pipe 22. An impeller 26 is fixed at one end of the rotating rod 25 located in the second water pipe 22.

[0040] During operation, the cleaning liquid enters the second water pipe 22 and flows along the inner wall of the second water pipe 22, and finally enters the nozzle 24 and is sprayed out to clean the atomization box 1. When the cleaning liquid flows, it drives the impeller 26 and the rotating rod 25 to rotate, thereby driving the nozzle 24 to rotate, expanding the spray range of the nozzle 24 and improving the cleaning effect.

[0041] The driving component includes a functional box 31 fixed to the top of the atomization box 1, a motor 32 is fixed to the top of the functional box 31, a reciprocating screw 33 is connected to the output shaft of the motor 32 through a coupling, and the end of the reciprocating screw 33 away from the motor 32 is rotatably connected to the cavity 14. The driving component also includes a transmission unit, which includes a first column gear 34 fixed to one end of the reciprocating screw 33 located in the cavity 14, and a second column gear 35 is fixed to one end of the first water pipe 21 located in the cavity 14, and the first column gear 34 and the second column gear 35 are meshed with each other.

[0042] During operation, the motor 32 drives the reciprocating screw 33 to rotate. Under the meshing action of the first column gear 34 and the second column gear 35, the first water pipe 21 drives the second water pipe 22 to rotate, so that the nozzle 24 disinfects and cleans the atomization box 1 in all directions.

[0043] The water storage component includes a box body 41 fixed below the atomizing box 1, a first water inlet 42 and a second water inlet 43 are provided on the box body 41, a universal wheel 44 is installed at the bottom of the box body 41, a liquid separation unit is provided in the box body 41, and the liquid separation unit includes a first rotating shaft 51 rotatably connected to the center of the box body 41, the first rotating shaft 51 passes through the top plate of the box body 41, the first rotating shaft 51 and the central axis 221 are connected through a reducer, a liquid separation plate 52 is fixed on the first rotating shaft 51, and the liquid separation plate 52 is connected to the side wall of the box body 41 and the box body The bottom plate of the box body 41 is sealed and slidably connected, the height of the separator plate 52 is higher than the height of the first water inlet 42 and the second water inlet 43, a stirring element is provided on one side of the separator plate 52, and the stirring element includes two mounting plates 53 fixed on the first rotating shaft 51, and the two mounting plates 53 are rotatably connected to the second rotating shaft 54, and the second rotating shaft 54 ​​is fixed with a spiral blade 55, and the top of the second rotating shaft 54 ​​is fixed with a third column gear 57, and the top plate of the box body 41 is fixed with an inner gear ring 56 meshing with the third column gear 57.

[0044] Before cleaning, disinfectant is loaded into one side of the liquid separation plate 52 where the stirring element is located, and pure water is loaded into the other side. During operation, the water supply component transports the disinfectant in the box body 41 to the second water pipe 22 to disinfect the atomizer box 1. At the same time, the central shaft 221 drives the first rotating shaft 51 to rotate slowly, and exchanges the positions of the disinfectant and pure water in the box body 41, so as to achieve disinfection and then cleaning of the atomizer box 1. When the first rotating shaft 51 rotates, it drives the mounting plate 53 and the second rotating shaft 54 ​​to rotate around the first rotating shaft 51. Under the meshing action of the third column gear 57 and the inner gear ring 56, the second rotating shaft 54 ​​drives the spiral blade 55 to rotate to stir the disinfectant, so as to avoid stratification due to the long-term standing of the disinfectant.

[0045] The water supply component includes a sliding rod 61 fixed in the function box 31, and a piston plate 62 is sealed and slidably connected to the sliding rod 61. The reciprocating screw 33 passes through the piston plate 62 and is threadedly connected to the piston plate 62. A drainage pipe 63 is arranged between the box body 41 and the function box 31, and a one-way valve is provided on the drainage pipe 63 to only allow liquid to enter the function box 31.

[0046] During operation, the reciprocating screw 33 rotates to drive the piston plate 62 to move up and down. When the piston plate 62 moves upward, the pressure in the function box 31 decreases, and the water or disinfectant in the box body 41 enters the function box 31. When the piston plate 62 moves downward, the water or disinfectant in the function box 31 is squeezed into the first water pipe 21, realizing pulse water supply.

[0047] The working principle of the present invention is as follows:

[0048] During treatment, the liquid medicine is poured into the atomizer box 1 from the medicine inlet 11, and the hose of the inhaler is fixed on the hose interface 12. The liquid medicine is atomized in the atomizer box 1 and then enters the inhaler for inhalation treatment by the patient.

[0049] Before cleaning, disinfectant and pure water are poured into the box 41 respectively, wherein the disinfectant is poured into the side of the liquid separation plate 52 where the stirring element is located.

[0050] When cleaning, open the end cover of the drain port 13, turn on the motor 32, the motor 32 drives the reciprocating screw rod 33 to rotate, thereby driving the piston plate 62 to reciprocate up and down. When the piston plate 62 moves upward, the pressure in the function box 31 decreases, and the disinfectant in the box body 41 enters the function box 31. When the piston plate 62 moves downward, the disinfectant in the function box 31 is squeezed into the first water pipe 21. After entering the first water pipe 21, the disinfectant enters the second water pipe 22 and is finally sprayed out by the nozzle 24 to disinfect the atomization box 1. When the disinfectant flows in the second water pipe 22, it drives the impeller 26 to rotate, and the rotation of the impeller 26 drives the rotating rod 25 and the nozzle 24 to rotate. The head 24 rotates to expand the spray range of the nozzle 24, avoid drug residue or drug liquid remaining in the atomization box, increase the service life of the device, and ensure the treatment effect. Through the pulsed water supply method, the drug residue is washed away from the inner wall of the atomization box when the nozzle sprays water. When the nozzle stops spraying water, the drug residue follows the water flow to the bottom of the atomization box, avoiding the nozzle continuously spraying water and causing part of the drug residue to fail to flow to the bottom of the atomization box, thereby improving the cleaning effect. When the reciprocating screw 33 rotates, under the meshing action of the first column gear 34 and the second column gear 35, the first water pipe 21 drives the second water pipe 22 to rotate, so that the nozzle 24 disinfects and cleans the atomization box 1 in all directions.

[0051] When the second water pipe 22 rotates, it drives the central shaft 221 to rotate. Under the action of the reducer, the first rotating shaft 51 rotates slowly, and the disinfectant and pure water in the box body 41 are exchanged, so that the atomizer box 1 is disinfected first and then cleaned. There is no need to manually replace the cleaning liquid. The operation is simple and the work efficiency is high. When the first rotating shaft 51 rotates, it drives the mounting plate 53 and the second rotating shaft 54 ​​to rotate around the first rotating shaft 51. Under the meshing action of the third column gear 57 and the inner ring gear 56, the second rotating shaft 54 ​​drives the spiral blade 55 to rotate to stir the disinfectant, so as to avoid stratification of the disinfectant due to long-term standing, thereby ensuring the disinfection effect of the disinfectant.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
