Abstract
Description
Technical Field
[0001] This invention relates to the field of medical nebulizer technology, and more particularly to a portable vibrating mesh nebulizer. Background Technology
[0002] Inhaled nebulized drug delivery is a common treatment for respiratory diseases. Vibrating mesh nebulizers are widely used in clinical and home settings due to their controllable atomization particle size and portability. However, most existing portable vibrating mesh nebulizers use a single drug storage chamber structure. If the drugs are two formulations that need to be mixed, they need to be exposed to air for premixing, which increases the contact time between the drugs and oxygen. Furthermore, some of the two drugs can undergo oxidation-reduction reactions after mixing, and some drugs may even precipitate, reducing drug activity. Drug deposits during nebulization can gradually clog the micropores of the nebulizer element, causing a decrease in nebulization volume or even interruption of nebulization, affecting the lifespan of the nebulizer element. In addition, the content of active ingredients in the nebulized drug decreases, affecting the therapeutic effect. Summary of the Invention
[0003] To overcome the shortcomings mentioned in the background above, the present invention provides a portable vibrating mesh atomizer.
[0004] The technical solution is as follows: A portable vibrating mesh atomizer includes a handle, an adapter block fixedly connected to the handle, an installation block fixedly connected to the adapter block, a microporous atomizing element and a duckbill-type one-way valve installed in the installation block, the microporous atomizing element and the duckbill-type one-way valve being connected in communication, a face mask being detachably connected to the installation block, a drug storage chamber fixedly connected to the adapter block, the drug storage chamber having two symmetrically distributed drug storage cavities, the two drug storage cavities being used to store different drug solutions respectively, the adapter block having drug solution flow channels corresponding to the drug storage cavities one by one, the drug solution flow channels being connected to the corresponding drug storage cavities, the adapter block having a manifold cavity, both drug solution flow channels being connected to the manifold cavity, the manifold cavity being connected to the duckbill-type one-way valve, the manifold cavity being used for drug solution mixing, and a first drug delivery tube fixedly connected to the drug storage chamber one by one, the first drug delivery tube being connected to the corresponding drug storage cavity, the first drug delivery tube being used for adding drug solution.
[0005] Furthermore, the first administration tube is slidably connected to the second administration tube, and a first return spring is fixed between the drug storage chamber and the second administration tube. The second administration tube has a first administration hole, and the first administration tube has a second administration hole. The first administration tube is used to block the corresponding first administration hole, and the second administration tube is used to block the corresponding second administration hole. The first administration hole and the corresponding second administration hole are used together to guide the liquid medicine into the corresponding drug storage chamber.
[0006] Furthermore, the width of the second administration orifice is smaller than the width of the first administration orifice.
[0007] Furthermore, the cross-section of the drug storage cavity is an inverted cone shape, which is used to guide the liquid medicine in the drug storage cavity to the corresponding liquid medicine flow channel.
[0008] Furthermore, the handle has a pressure chamber, a piston rod is slidably connected to the pressure chamber, and symmetrically distributed air guide tubes are fixed to the handle. All air guide tubes are connected to the pressure chamber, and the air guide tubes pass through the adapter block and the drug storage compartment and are connected to the corresponding drug storage compartment. A second return spring is provided between the handle and the piston rod, and a sliding plate is fixed to the piston rod. The sliding plate is slidably connected to the handle and is used to drive the piston rod to move.
[0009] Furthermore, the connection point between the air guide tube and the corresponding drug storage chamber is located at the upper part of the drug storage chamber.
[0010] Furthermore, a damping rod is installed inside the handle, and the telescopic end of the damping rod is fixedly connected to the sliding plate. The damping rod is used to realize the slow upward movement of the sliding plate.
[0011] Furthermore, the adapter block is provided with spiral guide grooves that correspond one-to-one with the liquid flow channels. The liquid flow channels are connected to the corresponding spiral guide grooves, and the spiral guide grooves are used to guide the liquid.
[0012] Furthermore, the liquid flow channel has a variable diameter section, which is used to change the liquid flow area.
[0013] Furthermore, the manifold is further provided with circumferentially distributed mixing blocks, which are used to agitate the liquid medicine.
[0014] Beneficial effects: This invention uses two independent drug storage chambers in the drug storage compartment to store different drug solutions. The drug is directly introduced into the corresponding drug storage chamber through the first drug delivery tube, reducing the time the drug solution is exposed to air to ensure the nebulization treatment effect. The two drug solutions are mixed only at the confluence chamber. The two drug solutions are isolated from each other before administration, further reducing the oxidation-reduction reaction that may occur due to premature contact between the two drug solutions and reducing the phenomenon of drug precipitation. The piston rod slides in the pressure chamber to generate negative pressure. When the first drug delivery port and the second drug delivery port are connected, the drug is drawn into the corresponding drug storage chamber. The first drug delivery tube blocks the first drug delivery port, and the second drug delivery tube blocks the second drug delivery port, effectively preventing outside air from entering the drug storage chamber, reducing the oxygen content in the drug storage chamber, further inhibiting drug oxidation and improving drug stability. Positive pressure drug delivery is achieved through the damping rod, and the spiral guide groove causes the drug to generate directional swirling flow. After the drug flow is accelerated by the variable diameter section, the two drugs are mixed more evenly under the guidance of the mixing block, improving the consistency of drug delivery and ensuring the therapeutic effect.

Detailed Implementation
[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0018] Example 1
[0019] A portable vibrating mesh atomizer, such as Figures 1-5 and Figure 7As shown, the device includes a handle 1, which houses a battery (not shown in detail in the figure). The outer shell has a silicone anti-slip surface and an atomizing switch. The battery powers the atomizing switch and the microporous atomizing element 4. The projection of the handle 1 onto the horizontal plane is elliptical. An adapter block 2 is fixedly attached to the handle 1, located on the upper side of the handle 1. A mounting block 3 is fixedly attached to the adapter block 2, located to the left of the adapter block 2. The mounting block 3 houses the microporous atomizing element 4 and a duckbill-type one-way valve 5. The microporous atomizing element 4 is located near the face mask 6, and the duckbill-type one-way valve 5 is located between the microporous atomizing element 4 and the manifold 10. The microporous atomizing element 4 and the duckbill-type one-way valve 5 are connected. The duckbill-type one-way valve 5 is used for one-way flow of the liquid medication and prevents air from entering the manifold 10. The mounting block 3 is detachably connected to a mask 6, which is located on the left side of the mounting block 3. The mask 6 is available in various models to suit different patients. The adapter block 2 is fixedly connected to a drug reservoir 7, which is located on the upper side of the adapter block 2. The drug reservoir 7 has two symmetrically distributed drug storage chambers 8. The cross-section of the drug storage chamber 8 is inverted conical, which is used to guide the liquid medication in the drug storage chamber 8 to the corresponding liquid medication channel 9. The inclined surface inside the drug storage chamber 8 allows the liquid medication to flow under its own weight. The liquids converge at the bottom and eventually flow through the corresponding liquid channel 9 to the confluence cavity 10. Two storage cavities 8 are used to store different liquids. The adapter block 2 has liquid channels 9 corresponding to the storage cavities 8, and these channels are connected. Both liquid channels 9 are at an angle to the horizontal plane. The side of the liquid channel 9 closest to the corresponding storage cavity 8 is higher than the side closest to the confluence cavity 10 to ensure the direction of liquid flow. The adapter block 2 has a confluence cavity 10 located on the left side of the adapter block 2. Both liquid channels 9 are connected to the confluence cavity 10. The axes of the two liquid channels 9 are aligned... The intersection point is located on the axis of the manifold 10. The liquid medicine flowing out of the liquid medicine channel 9 will be mixed in the manifold 10 and quickly absorbed by the negative pressure generated by the high-frequency vibration of the mesh in the microporous atomizing element 4, so that the mixed liquid medicine moves towards the mask 6 and finally achieves atomization. The manifold 10 is connected to the duckbill type one-way valve 5. The manifold 10 is used to supply liquid medicine mixing. The drug storage chamber 7 is fixedly connected to the first drug delivery tube 11 corresponding to the drug storage chamber 8. The first drug delivery tube 11 is connected to the corresponding drug storage chamber 8. The first drug delivery tube 11 is located on the upper side of the drug storage chamber 7 and is cylindrical. The first drug delivery tube 11 is used to add liquid medicine.
[0020] like Figure 1 and Figures 3-5As shown, a first administration tube 11 is slidably connected to a second administration tube 12. The second administration tube 12 has an inverted T-shaped cross-section. The axis of the first administration tube 11 is collinear with the axis of the corresponding second administration tube 12. The second administration tube 12 has a hollow cylindrical structure. A first return spring 13 is fixedly connected between the drug storage chamber 7 and the second administration tube 12. The first return spring 13 is used to return the second administration tube 12 to its original position. Under normal conditions, the first return spring 13 is at its natural length. The upper surface of the second administration tube 12 is higher than the upper surface of the corresponding first administration tube 11. The second administration tube 12 has two centrally symmetrically distributed first administration holes 14, which are located on the upper left and right sides of the corresponding second administration tube 12. The first administration tube 11 has two centrally symmetrically distributed second administration holes 15, which are located below the corresponding first administration tube 11. On the left and right sides of the part, the first administration tube 11 is a cylindrical tube closed at one end. The width of the second administration hole 15 is smaller than the width of the first administration hole 14 to ensure the entry of the liquid medicine when the first administration hole 14 and the corresponding second administration hole 15 are connected. When the second administration tube 12 is pressed and the corresponding first administration hole 14 is moved down, the second administration hole 15 is used to connect with the corresponding first administration hole 14, so that the corresponding second administration tube 12 and the corresponding first administration tube 11 are connected to allow the liquid medicine to enter. The first administration tube 11 is used to block the corresponding first administration hole 14, and the second administration tube 12 is used to block the corresponding second administration hole 15. Under normal conditions, the second administration tube 12 blocks the corresponding second administration hole 15, and the first administration tube 11 blocks the corresponding first administration hole 14. The first administration hole 14 and the corresponding second administration hole 15 are used together to guide the liquid medicine into the corresponding drug storage chamber 8.
[0021] like Figure 1 and Figures 6-8As shown, the handle 1 has a pressure chamber 16 located on the upper right side of the handle 1. A piston rod 17 is slidably connected to the pressure chamber 16. The piston rod 17 consists of a piston plate and a cylindrical rod. The piston plate of the piston rod 17 slidably seals with the pressure chamber 16, while the cylindrical rod of the piston rod 17 does not seal with the handle 1. The piston rod 17 is located on the upper right side of the handle 1, and its cross-section is T-shaped. Positive or negative pressure is generated in the pressure chamber 16 by the upward or downward movement of the piston rod 17. Two symmetrically distributed air guide tubes 18 are fixed to the handle 1. All air guide tubes 18 are connected to the pressure chamber 16. Located above pressure chamber 16, the air guide tube 18 is a non-collapseable rigid tube. The air guide tube 18 passes through the adapter block 2 and the drug storage chamber 7 and communicates with the corresponding drug storage chamber 8. The air guide tube 18 is used to draw air from the corresponding drug storage chamber 8, creating a negative pressure within it. When the second drug delivery tube 12 and the corresponding first drug delivery tube 11 of the drug storage chamber 8 are connected, the drug solution is rapidly drawn in through the corresponding second drug delivery port 15 and the corresponding first drug delivery port 14 under the negative pressure, reducing the time the drug solution is exposed to air. The connection point between the air guide tube 18 and the corresponding drug storage chamber 8 is located at the upper part of the drug storage chamber 8. The angle between the upper air inlet of the air duct 18 and the horizontal plane is less than 90° to prevent the accumulated medicine from being sucked into the air duct 18. A second return spring 19 is provided between the handle 1 and the piston rod 17. The second return spring 19 is located inside the pressure chamber 16 and sleeved on the outside of the piston rod 17. The second return spring 19 is used to return the piston rod 17 to its original position. Under normal conditions, the second return spring 19 is in its natural state. A sliding plate 20 is fixedly connected to the piston rod 17. The sliding plate 20 is located below the piston rod 17 and is slidably connected to the handle 1. The sliding plate 20 passes through the handle 1 and is used to drive the piston rod 17. When the piston rod 17 moves, a damping rod 21 is installed inside the handle 1. The telescopic end of the damping rod 21 is fixed to the sliding plate 20. The damping rod 21 is used to realize the slow upward movement of the sliding plate 20. When the sliding plate 20 is slid downward, the piston rod 17 moves down and compresses the second return spring 19. The sliding plate 20 compresses the telescopic end of the damping rod 21. After the sliding plate 20 is released, the piston rod 17 moves up slowly under the combined action of the damping force of the damping rod 21 and the elastic force of the second return spring 19, and a positive pressure environment is generated in the pressure chamber 16 and the drug storage chamber 8 to promote the flow of the drug liquid in the drug storage chamber 8 and increase the flow rate of the drug liquid.
[0022] Working principle: When nebulization therapy is required, open the two ampoules containing the medication (hereinafter referred to as Medication One and Medication Two). Then, press down on the sliding plate 20, causing it to slide downwards relative to the handle 1. Simultaneously, this moves the piston rod 17 downwards. During this process, the second return spring 19 is compressed, the extension end of the damping rod 21 retracts, and negative pressure is generated in the pressure chamber 16. This negative pressure is then generated in both drug storage chambers 8 through the air guide tube 18 until the sliding plate 20 reaches its limit position. Subsequently, the ampoule containing Medication One is inverted and inserted into one of the second drug delivery tubes 12. The ampoule is then pressed down further, causing the second drug delivery tube 12 to continue moving downwards and compressing the corresponding first return spring 13 until the first drug delivery hole 14 corresponding to the second drug delivery tube 12 is reached. The ampoule is connected to the corresponding second administration port 15 and the corresponding first administration tube 11. At this time, the first drug solution is instantly drawn into the storage chamber 8 through the corresponding first administration port 14, the corresponding second administration port 15 and the corresponding first administration tube 11 under the negative pressure of the storage chamber 8. After the first drug solution in the ampoule is emptied, the ampoule is removed. Under the push of the first return spring 13, the corresponding second administration tube 12 is reset relative to the corresponding first administration tube 11. At this time, the storage chamber 8 is in a state of near-normal pressure. The first administration port 14 is blocked by the corresponding first administration tube 11 and the second administration port 15 is blocked by the corresponding second administration tube 12. The method of adding the second drug solution is the same as that of the first drug solution. After the drug solution is added, the pressure chamber 16 and the two storage chambers 8 are in a state of near-normal pressure.
[0023] Then, press the switch on the handle 1 to activate the microporous atomizing element 4 and release the sliding plate 20. Under the push of the second return spring 19 and the restriction of the extension end of the damping rod 21, the piston rod 17 slowly moves upward. During this process, the piston rod 17 compresses the air in the pressure chamber 16, causing the pressure in the pressure chamber 16 to increase. After passing through the two air guide tubes 18, the pressure in the corresponding drug storage chamber 8 increases, making the drug storage chamber 8 a positive pressure state. This allows drug liquid one and drug liquid two to flow into the manifold 10 through the corresponding drug liquid flow channels 9. In the manifold 10, drug liquid one and drug liquid two mix. After passing through the duckbill one-way valve 5, the mixed drug liquid is quickly absorbed and atomized by the negative pressure generated by the microporous atomizing element 4, prolonging the contact time between the two drug liquids. During the process, reduce the oxidation-reduction reaction that occurs due to premature contact between the two medications, and reduce the precipitation of drugs. Continue until both medications are used up. Press the switch on the handle 1 to turn off the microporous nebulizer element 4. If the sliding plate 20 has not returned to its original position relative to the handle 1 at this time, wait for the sliding plate 20 to return to its original position relative to the handle 1. If the sliding plate 20 has already returned to its original position, there is no need to wait. Then, inject clean water into the nebulizer through the first administration tube 11, the second administration tube 12, the first administration port 14, and the second administration port 15, and press and hold the switch on the handle 1 to enter the cleaning mode. After cleaning, let the device air dry. The nebulization treatment is now complete. If nebulization treatment is needed again, repeat the above operation.
[0024] Example 2
[0025] Based on Example 1, such as Figure 2 , Figure 3 and Figure 9 As shown, the adapter block 2 has spiral guide grooves 22 corresponding to the liquid flow channels 9. The spiral guide grooves 22 are located on the inner wall of the corresponding liquid flow channels 9. After the liquid flows through the corresponding spiral guide grooves 22, it will rotate and generate swirling flow, which facilitates the subsequent improvement of the uniformity of the liquid mixture. The liquid flow channels 9 are connected to the corresponding spiral guide grooves 22. The liquid flow channels 9 have a variable diameter section 23, which is used to change the flow area of the liquid. The flow area of the variable diameter section 23 gradually decreases from the side away from the manifold 10 to the side closer to the manifold 10. The flow rate of the two medicinal solutions is increased in one step, so that they collide and mix after entering the manifold 10. The spiral guide groove 22 is used to guide the medicinal solution. Three circumferentially distributed mixing blocks 24 are fixed in the manifold 10, and all three are located on the lower side of the manifold 10. The mixing blocks 24 are used to disturb the medicinal solution. After the medicinal solution is mixed by its own swirling and impact, it generates turbulence when it comes into contact with the mixing blocks 24 and makes the medicinal solution flow randomly, which further improves the mixing efficiency of the two medicinal solutions and enhances the uniformity of the mixed medicinal solution, thereby improving the therapeutic effect.
[0026] Working principle: As the first liquid flows through the corresponding liquid flow channel 9 to the manifold 10, the first liquid rotates and generates a swirling flow when it flows through the spiral guide groove 22. As the first liquid continues to flow, after passing through the variable diameter section 23, the flow area of the variable diameter section 23 decreases, and the flow speed of the first liquid further increases. Finally, it enters the manifold 10. The second liquid is the same as the first liquid. After passing through the corresponding spiral guide groove 22 and the variable diameter section 23, it enters the manifold 10. The first liquid and the second liquid collide and mix for the first time before contacting the mixing block 24. At this time, the first liquid and the second liquid are in disordered flow and collide repeatedly between all the mixing blocks 24, which further improves the mixing rate and improves the mixing uniformity, ensuring the therapeutic effect, until the mixed liquid is absorbed and atomized by the negative pressure generated by the microporous atomizing element 4. The subsequent operation is the same as in Example 1.

They should not be construed as limiting the scope of protection of the present invention.
