Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to an atomization device. Background Art

[0002] The nebulizer device used for pulmonary inhalation mainly converts liquid preparations such as drugs, nutrients or nicotine liquid into tiny particles that can be inhaled into the human body through breathing, thereby achieving the purpose of painless, rapid and effective treatment.

[0003] At present, most of the atomizers on the market are disposable equipment. After the medicine bottle is installed inside the device body, it is difficult to disassemble. After the liquid medicine is consumed, the user can only discard it and replace it with a new one, which leads to high cost of use and waste of resources. Even if some atomizers support the replacement of medicine bottles, the medicine replacement operation is still relatively cumbersome, and it is easy to cause pollution to the internal structure of the device (such as pollution caused by mixing different medicines in the nozzle module, tube rack assembly, etc.) and / or affect the dosage accuracy (such as dosage changes caused by the displacement of the spring and tube rack assembly), which is not conducive to subsequent reuse by users.

[0004] In view of this, the present application proposes an atomization device that can quickly change medicines and at the same time solves the problems of device contamination and / or dosage fluctuations. Summary of the invention

[0044] Now, the exemplary embodiments will be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this invention will be more complete and comprehensive, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their repeated description will be omitted.

[0045] The words describing the expression position and direction in the present invention are all illustrated by taking the attached drawings as examples, but can be changed according to needs, and all the changes made are included in the protection scope of the present invention.

[0046] See Figures 1 to 12 As shown, the present invention discloses an atomizing device, which includes a housing 1, an upper sleeve 2, a medicine bottle 3, a lower sleeve 4 and a driving mechanism 5.

[0047] Among them, the housing 1 is generally a circular tube structure with both ends open, and its top and bottom are respectively used to connect the upper sleeve 2 and the lower sleeve 4 to form a slender pen-like appearance shape (see Figure 1 ), which is convenient to carry and beneficial to privacy protection. In some embodiments, the device can be designed to have a total length of 110 mm - 120 mm and a diameter of 16 mm - 20 mm for easy carrying and use.

[0048] See Figure 2 and Figure 3 As shown, in the atomizing device, the upper sleeve 2 is detachably arranged at the top of the housing 1 and forms a first space therewith, so as to facilitate the independent taking / putting of the medicine bottle 3, and a spray nozzle 21 is arranged at the top of the upper sleeve 2, and the spray can be released outward from this opening. It should be noted that in the present invention, the medicine bottle 3 supporting the device is a disposable item, which is replaceably arranged in the first space, and the capacity of the medicine bottle 3 is approximately 0.3 ml - 0.5 ml, which can be determined according to the specific needs of the patient. And, as Figure 4 and Figure 5 shown, the bottom of the medicine bottle 3 is open and a piston 31 for sealing the liquid is built in, and a nozzle module 32 for atomizing the liquid is arranged at the top. When in use, the piston 31 squeezes the liquid in the bottle, and the pressurized liquid is processed by the nozzle module 32 and can be transformed into mist-like droplets and released outward at one time, that is, the so-called spray is formed.

[0049] The lower sleeve 4 is rotatably arranged at the bottom of the housing 1 and forms a second space therewith for independently arranging the driving mechanism 5, so as to separate it from the medicine bottle 3 and avoid affecting the stability of its own driving. Combining Figure 6 shown, the driving mechanism 5 is arranged in the second space and part of it is connected to the lower sleeve 4. The driving mechanism 5 includes a push rod 53 extending into the medicine bottle 3 and connected to the piston 31. The push rod 53 is used to dock with the piston 31 to apply a constant thrust to it.

[0050] See Figures 1 to 3 shown, the atomizing device of the present invention has two states: excitation and loading. As Figure 3 shown, in the excitation state, the push rod 53 can drive the piston 31 to move upward, so that the piston 31 squeezes the liquid in the bottle. After being atomized by the nozzle module 32, the liquid in the medicine bottle 3 is released at one time to form a spray. After the atomization is completed, as Figure 2As shown, rotating the lower sleeve body 4 can cause the push rod 53 to move downward, and the device returns to the loading state (for the state switching of the device and the principle of the driving mechanism 5, please refer to the following description). After each use of the device, the patient can quickly remove the used old medicine bottle 3 and replace it with the required new medicine bottle 3 by disassembling the upper sleeve body 2, waiting for the next use. It has the advantages of being reusable and convenient for changing medicine.

[0051] It is worth mentioning that in this application, the medicine bottle 3 and the driving mechanism 5 are separated in two independent spaces, and when the medicine bottle 3 is replaced, it only contacts the head of the push rod 53 of the driving mechanism 5. Therefore, it can effectively prevent the influence on the other components of the driving mechanism 5, thereby reducing or even completely avoiding the influence on the stroke accuracy or thrust stability of the driving mechanism 5. On the other hand, in this application, the nozzle module 32 is directly integrated at the mouth of the medicine bottle 3 instead of the upper sleeve body 2 of the device. While simplifying the structure of the device itself and reducing costs, it can effectively ensure that the next spray will not be mixed with the residue of the previous spray, resulting in contamination, and improving the safety of medication. Furthermore, the capacity of the disposable medicine bottle 3 is limited at the factory. With a stable thrust output, it is ensured that the liquid in the bottle can be completely released at one time, and the consistency of each spray of the device is better, which is helpful for the patient to use medicine accurately in daily life.

[0052] See Figure 2 and Figure 3 As shown, in some embodiments, the top of the outer shell 1 is provided with a first connecting portion 11 extending upward, and the bottom of the upper sleeve body 2 is provided with a second connecting portion 22 extending downward, and the two are cooperatively connected to each other. For example, the first connecting portion 11 and the second connecting portion 22 can be detachably connected together by means of threads, snap connections, plug connections, etc., which is convenient for disassembly and assembly.

[0053] See Figure 4 and Figure 5 As shown, in some embodiments, at least two sealing rings 311 are provided on the outer periphery of the piston 31 to enhance the seal between the piston 31 and the medicine bottle 3, prevent liquid leakage, and ensure the reliability of liquid storage. In addition, at least three protrusions 312 are provided at intervals on the bottom of the piston 31. The protrusions 312 can reduce the area of the push rod 53 acting on the piston 31, increase the pressure, and thus make it easier to push the piston 31 to move.

[0054] Still as Figure 2 and Figure 3 As shown, in some embodiments, a push platform 6 is provided at the top of the push rod 53. Different pistons 31 can be adapted through the push platform 6, and the versatility is better. Moreover, the push platform 6 can evenly distribute the thrust to each protrusion 312, causing the piston 31 to move smoothly.

[0055] Preferably, the push rod 53 and the piston 31 are connected to each other through a quick-connection structure. As Figure 11As shown, the quick-connect structure includes a T-shaped head 531 provided at the top of the push rod 53 and a docking hole 61 provided on the push table 6. Among them, the docking hole 61 consists of two parts, namely a bottom hole 611 axially provided at the lower end of the push table 6 and a T-shaped hole 612 radially provided on the side of the push table 6. In this docking hole 61, the bottom hole 611 has a flared section and a mating section arranged from bottom to top, and the T-shaped hole 612 is in communication with the bottom hole 611 and matches the T-shaped head 531.

[0056] During assembly, the T-shaped head 531 is axially aligned with the bottom hole 611, and after passing through the flared section, it enters the mating section, causing the T-shaped head 531 to be locked by the mating section, that is, the connection between the push rod 53 and the push table 6 is quickly completed. When separating, a radially applied force is exerted on the T-shaped head 531, causing local micro-deformation of the T-shaped hole 612 until the T-shaped head 531 moves outwards from the T-shaped hole 612, which has the advantages of convenient and efficient disassembly and assembly.

[0057] See Figure 5 As shown, in some embodiments, an installation groove 33 is provided at the top of the medicine bottle 3, and the nozzle module 32 is integrally provided in the installation groove 33. The nozzle module 32 can be integrated by components such as a filter element 321 and an atomization chip 322. Among them, the filter element 321 plays a role of pre-filtration, and its filtration accuracy is approximately between 0.1 mm and 0.5 mm, which is used to intercept large-particle impurities in the liquid to avoid clogging of the atomization chip 322. The atomization chip 322 is held above the filter element 321, such as clamped by an elastic member on the outer periphery, and the atomization chip 322 has a multi-stage filtration structure (not shown) inside. After the pressurized liquid passes through the multi-stage filtration structure, fine liquid droplets can be formed, thereby realizing the atomization function. In this application, the nozzle module 32 is prefabricated and integrated into one body, and can be quickly installed in the installation groove 33, which is convenient for connecting with the medicine bottle 3 to form an integral structure.

[0058] Furthermore, as Figure 6 shown, a sealing ring 34 is provided at the bottom of the nozzle module 32. The sealing ring 34 is used to prevent liquid leakage to maintain a high-pressure environment of the liquid at the nozzle module 32 to ensure that the liquid can be effectively atomized. In addition, a fastener 35 is provided at the top of the nozzle module 32. The fastener 35 is fixedly connected to the medicine bottle 3, such as by screw connection, ultrasonic connection, etc., to enhance the fixing effect of the nozzle module 32.

[0059] See Figure 1 As shown, in some embodiments, the medicine bottle 3 is made of a transparent material, such as glass, PET, PP, PE, etc., and at least one viewing window 23 is provided on the side wall of the upper sleeve 2. The viewing window 23 corresponds to the position of the medicine bottle 3. This design allows the patient to observe the internal situation of the medicine bottle 3 through the viewing window without opening the upper sleeve 2, so as to know whether a new medicine bottle 3 needs to be replaced, which is convenient for operation.

[0060] See Figures 1 to 3 As shown, in some embodiments, air inlet holes 24 are symmetrically arranged on both sides of the upper sleeve body 2. The air inlet holes 24 communicate with the spray nozzle 21 through an air flow channel (formed by the inner wall of the upper sleeve body 2 and the outer wall of the medicine bottle 3). During the release of the spray by the device, the air inhaled from the air inlet holes 24 is accelerated under extrusion in the air flow channel. When it contacts the fine droplets released at the spray nozzle 21, it will further break them again, thereby improving the atomization effect.

[0061] Furthermore, a diversion groove 25 connecting the air inlet holes 24 and the spray nozzle 21 is arranged on the inner wall of the upper sleeve body 2, and the air flow channel is located in the diversion groove 25. Due to the influence of tolerance on the assembly of the medicine bottle 3 and the upper sleeve body 2, the air flow channel may be blocked after their assembly. The existence of the diversion groove 25 completely solves the problem of the blocked air flow channel, resulting in a significant improvement in the pneumatic performance of the device.

[0062] The driving mechanism 5 of the device will be described in detail below. See Figure 6 As shown, the driving mechanism 5 includes an actuating member 55 arranged in the outer shell 1 and capable of moving radially. Exemplarily, the actuating member 55 is an annular member, which is used to contact and cooperate with a part of the driving mechanism 5 (the rotating body 51 and the pipe bracket 52) to control the state of the device.

[0063] As Figure 2 and Figure 7 shown, in the loaded state, the actuating member 55 can lock the push rod 53 at the first position. At this time, the piston 31 is still at the bottom of the medicine bottle 3, and the device is waiting to be used. Continue to see Figure 3 and Figure 8 shown, after entering the firing state, the actuating member 55 can unlock the push rod 53 from the first position, causing it to quickly move up to the second position. At this time, the piston 31 moves to the top of the medicine bottle 3, and the device can release the spray outward.

[0064] Specifically, still as Figure 2 and Figure 3 shown, the driving mechanism 5 in the present invention further includes a rotating body 51, a pipe bracket 52, and a spring 54. Among them, the rotating body 51 has a tubular structure, which is rotatably arranged in the outer shell 1 and partially extends into the lower sleeve body 4 and is connected to it. By rotating the lower sleeve body 4, the rotating body 51 can be driven to rotate. The pipe bracket 52 is generally in an H-shaped structure, and its middle part is connected to the push rod 53. For example, they can be integrally formed. The pipe bracket 52 is arranged in the rotating body 51 and always rotates with the rotating body 51; in addition, the pipe bracket 52 can also move up and down along the axial direction of the rotating body 51 to control the push rod 53 to make corresponding movements. The spring 54 is arranged below the pipe bracket 52, and after being compressed, it can provide a constant thrust to the push rod 53 through the pipe bracket 52. Among them, in the loaded state, as Figure 2 and Figure 7As shown, the actuator 55 intersects the rotating body 51 eccentrically and presses and limits the top part of the pipe support 52. At the same time, the spring 54 is compressed to store energy, and the device waits for use. In the excitation state (when the actuator 55 is radially translated by pressing), as Figure 3 and Figure 8 shown, when the actuator 55 is coaxial and collinear with the rotating body 51, the actuator 55 will release the restriction on the top part of the pipe support 52, causing the spring 54 to expand to push the pipe support 52 upward. At this time, under the action of the push rod 53, the piston 31, and the device can spray outward.

[0065] As can be seen from the above, the drive mechanism 5 of the present invention has a compact structure, convenient operation, and compared with the hand-push drive mode, the spring 54 can provide a more stable thrust for the push rod 53 each time, significantly improving the atomization effect of the device.

[0066] Furthermore, referring to Figure 9 shown, the drive mechanism 5 further includes a guiding part 56 provided on the inner top of the housing 1. The guiding part 56 can be integrally formed with the housing 1, and a first helical surface 561 is provided at the bottom of the guiding part 56. Correspondingly, a second helical surface 521 is provided on the inner wall of the pipe support 52. Among them, the second helical surface 521 can closely adhere to the first helical surface 561 under the action of the spring 54, that is, when the device enters the excitation state and after the atomization ends, the patient can rotate the rotating body 51 to make the second helical surface 521 move downward under the guidance of the first helical surface 561 and compress the spring 54 through the pipe support 52 until the device is switched back to the loading state and waits for the next use. Preferably, the number of the first helical surfaces 561 is two, symmetric about the center of the guiding part 56. Similarly, the number of the second helical surfaces 521 is also two, symmetric about the center of the pipe support 52.

[0067] Even further, referring to Figures 6 to 8 shown, a reset part 551 is provided on one side of the actuator 55 (specifically, the side far from the pressing force application), and a first biasing surface 5511 is provided on the reset part 551. Correspondingly, a mating part 511 is provided on each side of the top of the rotating body 51, for example, symmetrically distributed at 180°, and a second biasing surface 5111 is provided on the mating part 511. Among them, by rotating the rotating body 51, the first biasing surface 5511 can be biased by the second biasing surface 5111 to drive the actuator 55 to switch from the coaxial and collinear state with the rotating body 51 to the eccentric intersection state, and at the same time, the top part of the pipe support 52 is pressed and limited, so that the device is reliably maintained in the loading state and waits for the next excitation.

[0068] Referring to Figure 10As shown, in some embodiments, a mating groove 13 is provided inside the outer shell 1, and convex wings 515 are provided on both sides of the top of the rotary body 51. Among them, the convex wings 515 are rotatably arranged in the mating groove 13, so that the rotary body 51 is rotatably connected to the outer shell 1.

[0069] In addition, a slot 41 is axially provided on the inner wall of the lower sleeve body 4, and a bayonet 42 is provided in the slot 41. On the outer wall of the rotary body 51, a convex block 512 and a spring arm 513 are axially provided. Among them, the convex block 512 is arranged in the slot 41, and part of the spring arm 513 is arranged in the bayonet 42, so that the rotary body 51 is rigidly connected to the lower sleeve body 4.

[0070] See Figure 6 As shown, in some embodiments, convex ribs 514 are axially provided on the inner wall of the rotary body 51, and grooves 523 are axially provided on the outer wall of the pipe support 5252. The convex ribs 514 and the grooves 523 are slidably engaged with each other, so that the pipe support 5252 can move up and down along its axis while rotating with the rotary body 51.

[0071] See Figure 9 As shown, in some embodiments, a guide hole 562 is provided at the center of the guide portion 56. The hole extends axially and its aperture is adapted to the push rod 53, and is used to guide the push rod 53 passing through it, so as to improve the stability of the up and down movement of the push rod 53.

[0072] Furthermore, the pipe support 52 has a convex platform 522 that abuts against the bottom of the guide hole 562. The convex platform 522 is used to keep the pipe support 52 connected to the push rod 53, which is convenient for the two to be integrally formed. On the other hand, the convex platform 522 can be in contact and cooperation with the bottom of the guide hole 562, so as to limit the upward movement stroke of the push rod 53, so that each upward movement stroke is kept uniform, thus ensuring the consistency of each spray.

[0073] See Figure 12 As shown, in some embodiments, a button 7 for connecting the actuating member 55 is provided on the outer shell 1, and the patient can operate and use the device through it. In addition, a plurality of support portions 12 are circumferentially spaced above the actuating member 55, and the two can be integrally formed. Each support member cooperates with the rotary body 51 to stably place the actuating member 55 in the outer shell 1.

[0074] Furthermore, a force - increasing section 121 is provided on some of the support portions 12 on the side away from the button 7. The force - increasing section 121 is inclined, and is used to increase the pressing resistance of the button 7, which can effectively prevent the device from being accidentally sprayed due to accidental touch and improve the reliability of the device. Exemplarily, the force - increasing section 121 can be formed by inclining downward from the inner edge of the lower end face of the corresponding support portion 12; or, the force - increasing section 121 can also be formed by inclining downward from the middle of the lower end face of the corresponding support portion 12.

[0075] Preferably, the angle α formed by the afterburner section 121 and the horizontal plane is 3°-6°. After repeated tests, if the angle α is less than 3°, the resistance effect of pressing is not obvious. If the angle α is greater than 6°, it will cause difficulty in pressing and inconvenient operation. When the angle α is between 3°-6°, it hardly affects the operation. Especially when the angle α is 5°, it has a good resistance effect.

[0076] See Figure 6 and Figure 12 As shown, in some embodiments, a guiding groove 552 is provided on the side of the actuator 55 away from the button 7, and the opening of the guiding groove 552 faces upward. Among the supporting portions 12, only one supporting portion 12 facing the button 7 is arranged in the guiding groove 552 and is slidably engaged therewith, thereby restricting the actuator 55 to move only in the pressing direction and ensuring the accuracy of its reset movement.

[0077] See Figure 1 As shown, in some embodiments, a cover 8 is provided on the upper sleeve 2, and the cover 8 functions to prevent dust and protect, avoiding the nozzle 21 from being contaminated.

[0078] In summary, the atomization device of the present invention operates as follows: Initially, the device is in the loading state. The patient can remove the upper sleeve 2 and install the required medicine bottle 3 on the top of the housing 1, making its piston 31 connected to the push rod 53 of the driving mechanism 5; Subsequently, the upper sleeve 2 is connected to the housing 1 again to fix the medicine bottle 3 in the device; Press the button 7 to make the driving mechanism 5 enter the firing state from the loading state. At this time, the push rod 53 pushes the piston 31 upward, prompting the device to generate a spray and release it outward; After atomization, rotate the lower sleeve 4 to switch the driving mechanism 5 from the firing state to the loading state. The patient repeats the previous actions to replace the new medicine bottle 3 and use it again.

[0079] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Without departing from the principles and purposes of the present invention, those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the invention, and all these changes should fall within the protection scope of the claims of the present invention.
