[0031] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the drawings represent identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0032] The words expressing positions and directions described in the present invention are all explained with reference to the accompanying drawings as examples, but can be modified as needed, and all such modifications are within the scope of protection of the present invention.

[0033] The invention discloses an atomizing inhalation device, which converts liquid preparations such as medicines and nutrients into tiny particles that can be inhaled into the human body through breathing, thereby achieving the purpose of atomization treatment.

[0034] 1 to 6 , the atomizing inhalation device includes a nozzle structure, which includes an upper shell 1 , an atomizing module 2 and a nozzle housing 3 .

[0035] As shown in Figures 2 and 4, the upper housing 1 is generally cylindrical, with a through cavity 101 disposed therein for mounting the atomizer module 2. For example, the through cavity 101 is coaxially arranged with the upper housing 1, and the two can be integrally formed by injection molding. The through cavity 101 extends downward from the top of the upper housing 1 and is approximately half the length of the upper housing 1.

[0036] As shown in Figures 2 and 3, the atomization module 2 mainly includes a flow-guiding member 201 and an atomization unit 204 connected to the flow-guiding member 201. Liquid medicine can be transported to the atomization unit 204 through the flow-guiding member 201 and converted into mist droplets under pressure for release.

[0037] The atomizer module 2 is disposed within the through-cavity portion 101, and the two are fixed by interference. Specifically, the flow-guiding member 201 can be inserted downwardly from the top of the upper housing 1 into the through-cavity portion 101, and the flow-guiding member 201 and the through-cavity portion 101 are used to achieve fixed installation of the atomizer module 2. Preferably, the flow-guiding member 201 has four fixed wings evenly distributed around the circumference, and each has an interference surface capable of contacting the through-cavity portion 101, thereby forming four linear interferences to reduce assembly resistance and effectively ensure the stability of the force applied to the flow-guiding member 201 after installation.

[0038] In addition, the outer periphery of the flow-guiding member 201 is provided with a ring edge 202 that rests against the upper end surface of the through-cavity portion 101. For example, the ring edge 202 is located below the atomizing unit 204, and its outer diameter is larger than the inner diameter of the through-cavity portion 101, ensuring that the ring edge 202 can completely rest against the upper end surface of the through-cavity portion 101, thereby limiting the insertion depth of the atomizing module 2 and preventing the atomizing unit 204 from colliding with or being scratched by the through-cavity portion 101, thereby damaging the atomizing structure. In addition, the ring edge 202 can also serve as an anti-falling function, thereby improving the reliability of the atomizing module 2 after assembly.

[0039] As shown in FIG2 , FIG3 and FIG6 , the nozzle shell 3 is roughly trumpet-shaped and is mounted on the top of the atomization module 2 to protect the atomization module 2 and form an aerodynamic layout to improve the atomization treatment effect.

[0040] The bottom of the nozzle shell 3 is separately connected to the upper shell 1, so that the flow guide component 201 will not be obstructed by the nozzle shell 3 during the process of being installed into the through cavity 101, which is convenient for operation and is conducive to the subsequent cleaning or maintenance of the atomization module 2.

[0041] The assembly method of the nozzle structure in the above-mentioned atomizing inhalation device is as follows:

[0042] S1. Provide an upper shell 1, an atomization module 2, and a nozzle housing 3;

[0043] S2. Insert the atomizer module 2 from the top of the upper housing 1 downward into the through cavity 101 until the ring edge 202 abuts against the upper end surface of the through cavity 101. Use the interference fit between the flow guide member 201 and the through cavity 101 to secure the atomizer module 2.

[0044] S3. The nozzle housing 3 is mounted on the top of the atomizing module 2, and the bottom of the nozzle housing 3 is fixed to the upper shell 1 by snapping. This completes the assembly of the nozzle structure.

[0045] Compared with the prior art, the atomizing inhalation device of the present application has made significant changes to the assembly of the nozzle structure. By assembling the flow-guiding member 201 from top to bottom, the problem of difficulty in docking the flow-guiding member 201 with the through-cavity portion 101 and inconvenient assembly operation after the device is miniaturized is solved. It can also prevent the atomizing unit 204 from colliding or being scratched, thereby avoiding damage to the atomizing structure.

[0046] Furthermore, the design of the outer ring 202 eliminates the need for step processing on the inner wall, and maintains the structural strength of the miniaturized through-cavity 101. The separate connection between the upper shell 1 and the nozzle housing 3 facilitates the installation of the atomizer module 2, improves the convenience of assembly operations, and also facilitates the cleaning and maintenance of the atomizer module 2.

[0047] Referring to Figures 2, 4, and 6, in one embodiment, a first protrusion 301 is provided on the inner bottom of the nozzle housing 3. Exemplarily, the first protrusion 301 is integrally formed with the nozzle housing 3, and the cross-sectional shape of the first protrusion 301 is arcuate. The through-cavity portion 101 extends upward from the interior of the upper housing 1 to form an exposed section 102, and the outer periphery of the exposed section 102 is provided with a first groove 103. Exemplarily, the cross-sectional shape of the first groove 103 is trapezoidal and adapts to the first protrusion 301.

[0048] By matching the first groove 103 with the first protrusion 301, the nozzle housing 3 can be detachably fixed to the upper housing 1. This solution has the advantages of simple structure and easy operation.

[0049] 2 to 6 , in a preferred embodiment, the inner wall of the through-cavity portion 101 is provided with a first slot 104, which extends along the length of the through-cavity portion 101. Correspondingly, a slider 203 is further provided on the outer periphery of the flow-guiding member 201, which slidably engages with the first slot 104. The first slot 104 and the slider 203 cooperate to guide the flow-guiding member 201 during installation, while also limiting the circumferential freedom of the flow-guiding member 201, thereby preventing the atomizing module 2 from rotating out of position.

[0050] Furthermore, the outer periphery of the exposed section 102 is provided with a second slot 105, extending along the length of the through-cavity 101. Correspondingly, the inner wall of the nozzle housing 3 is provided with a rib 302, which engages with the second slot 105. The engagement of the second slot 105 with the rib 302 guides the nozzle housing 3 during installation and limits its circumferential freedom, thereby preventing rotational deviation.

[0051] The above solution utilizes the first slot 104 to cooperate with the slider 203 and the second slot 105 to cooperate with the rib 302, so that the positions of the upper shell 1, the atomization module 2 and the nozzle shell 3 are always consistent, thereby improving the assembly accuracy and the stability of the nozzle structure.

[0052] Referring to Figures 2 and 3, in a preferred embodiment, air holes 303 are provided on each side of the nozzle housing 3, and the air holes 303 are used to introduce external air. In addition, a plurality of ventilation grooves 304 are provided on the inner wall of the nozzle housing 3, and the ventilation grooves 304 are spaced around the periphery of the atomization module 2 to ensure that the air inhaled from the air holes 303 can flow to the atomization unit 204, thereby avoiding the problem of poor air flow caused by the assembly of the atomization unit 204 and / or the nozzle housing 3 due to tolerance reasons. The air inhaled from the air holes 303 can be mixed with the medicine released by the atomization module 2 after passing through the ventilation grooves 304, and the medicine droplets are further broken into soft mist under the mechanism of Rayleigh rupture, thereby improving the atomization effect.

[0053] 17 to 19 , in one embodiment, the atomization unit 204 includes a pre-filter 2041 and a chip 2042 that are sequentially arranged from bottom to top.

[0054] Pre-filter 2041 can be a PE filter. PE filters have good chemical stability and mechanical strength, and are not susceptible to hydration, making them suitable for front-end filtration of chip 2042. Pre-filter 2041 has a filtration accuracy of approximately 0.1mm-0.5mm, ensuring that larger particles and debris are intercepted to prevent clogging of chip 2042.

[0055] Chip 2042 comprises a first plate 20421, a second plate 20422, and a multi-stage filtration structure. In chip 2042, the second plate 20422 is positioned above the first plate 20421, with an inlet 20426 and an outlet 20427 formed at either end of the chip 2042. The agent enters the chip 2042 through the inlet 20426 and is converted into tiny droplets before being ejected from the outlet 20427. The multi-stage filtration structure is positioned between the first plate 20421 and the second plate 20422. It comprises a first microstructured filtration unit 20423, a second microstructured filtration unit 20424, and a third microstructured filtration unit 20425, arranged sequentially along the liquid flow direction. This achieves three-stage filtration of the liquid and minimizes the size of the ejected agent droplets.

[0056] Liquid medicine within flow-guiding member 201 passes through pre-filter 2041 and enters chip 2042. It is then filtered and refined by first, second, and third microstructured filtration units 20423, 20424, and 20425 before being ejected from outlet 20427 of chip 2042, forming fine droplets. During this process, air drawn in through pores 303 is squeezed and accelerated after passing through ventilation grooves 304. Upon contact with the droplets, it further breaks them apart (i.e., Rayleigh fracture), forming the desired soft mist.

[0057] Furthermore, as shown in FIG19 , in the chip 2042, the first microstructured filtration unit 20423 and the second microstructured filtration unit 20424 can be integrally formed on the first layer 20421, and the third microstructured filtration unit 20425 can be integrally formed on the second layer 20422, with a portion of the third microstructured filtration unit filling a portion of the second microstructured filtration unit 20424. By designing the chip 2042 as a double-layer structure, with the first microstructured filtration unit 20423 and the second microstructured filtration unit 20424 formed on the first layer 20421 and the third microstructured filtration unit 20425 formed on the second layer 20422, the concentrated etching of the first microstructured filtration unit 20423, the second microstructured filtration unit 20424, and the third microstructured filtration unit 20425 can be avoided (if the microstructure pattern is etched on a single layer, the precision requirement is higher), thereby reducing the precision requirements of the multi-stage filtration structure and facilitating the production of the chip 2042.

[0058] Furthermore, as shown in FIG18 , the chip 2042 includes two outlets 20427 symmetrically arranged about the centerline of the chip 2042. This dual-outlet 20427 design provides a larger atomization area, allowing the agent to be fully atomized and forming more and smaller droplets. Furthermore, the angle formed by the extended lines of the jet directions of the two outlets 20427 is an obtuse angle. This results in relatively dispersed jet directions, allowing the sprayed agent droplets to diffuse and mix over a longer distance, thereby forming a larger, more uniform atomization range. This improves the spray coverage, allowing the agent droplets to be more evenly distributed throughout the spray area, achieving a better atomization effect. Furthermore, the obtuse angle can also reduce mutual interference and collisions between the agent droplets during the spraying process, reduce aggregation between the agent droplets, and further refine the size of the agent droplets, thereby improving the quality effect.

[0059] 1 , 7 and 8 , in one embodiment, the atomizing inhalation device further includes a liquid storage structure, which includes a lower shell 4 , a bottle body 5 , a spring seat 6 , a fitting 7 and a viewing window 8 .

[0060] The lower housing 4 in the first liquid storage structure is generally cylindrical, with a cavity within it for accommodating components such as the bottle body 5 and spring seat 6. Lower housing 4 is preferably made of an opaque material. This reduces light exposure to the liquid in the bottle, helping to maintain its stability and effectiveness; it also prevents exposure of internal components within lower housing 4, which could affect the overall aesthetics of the device.

[0061] The lower housing 4 is disposed below the upper housing 1, and when assembled, the two form the main body of the aerosol inhalation device. Typically, the upper housing 1 and lower housing 4 are assembled so as to be inseparable to ensure medication safety. Of course, in some other embodiments, the upper housing 1 and lower housing 4 can also be disassembled after assembly.

[0062] The bottle body 5 is disposed within the lower housing 4 and is made of a transparent material, such as transparent plastic or glass, to ensure visibility of the medicine within the bottle body 5. Furthermore, a cap 9 is provided at the mouth of the bottle body 5 to seal the mouth and secure the bottle body 5 in place. The cap 9 is made of a rigid material, such as aluminum.

[0063] The spring seat 6 is arranged inside the lower shell 4 . The spring seat 6 is located above the bottle body 5 and its position remains unchanged, thereby serving as a basis for fixing the bottle body 5 .

[0064] The fitting member 7 is provided on the cap 9 . For example, a docking portion 901 is provided on the upper end of the cap 9 . The fitting member 7 is threadedly mounted on the outer periphery of the docking portion 901 to achieve the connection and fixation between the fitting member 7 and the cap 9 .

[0065] The outer wall of the mating member 7 engages with the inner wall of the spring seat 6 to secure the bottle body 5 in its preset position. For example, the outer wall of the mating member 7 is provided with a second groove 701; correspondingly, the inner wall of the spring seat 6 is provided with a second protrusion 601. The second groove 701 and the second protrusion 601 cooperate to secure the mating member 7 to the spring seat 6. Since the position of the spring seat 6 is fixed, the bottle body 5 is also restrained in the preset position.

[0066] The viewing window 8 is provided on the side wall of the lower shell 4 . There is at least one viewing window 8 . The viewing window 8 is preferably made of transparent plastic and corresponds to the position of the bottle body 5 so that the user can see the medicine in the bottle body 5 through the viewing window 8 .

[0067] By restricting the position of the bottle body 5 and providing a viewing window 8 on the lower housing 4, the user can observe the medication usage, remaining amount, quality, and safety in real time through the viewing window 8, ensuring accurate and safe treatment. Compared to the liquid storage structure in existing atomizing inhalation devices, this device solves the problem of the bottle body 5 moving upward during use, preventing the user from viewing the medication inside the bottle due to the obstruction of the spring 12, thereby improving user convenience.

[0068] Furthermore, as shown in FIG8 , the edge of the cap 9 extends to the lower end surface of the spring seat 6 and abuts against the lower end surface, forming a step-like stop structure, and cooperates with the inner bottom of the lower shell 4 to clamp the bottle body 5, limiting its axial freedom, preventing the spring seat 6 and the mating piece 7 from being forced to separate, and strengthening the fixing effect on the bottle body 5.

[0069] In the aforementioned liquid storage structure, since the bottle body 5 is fixed in position, to ensure the normal function of the drug delivery function, the infusion tube 11 must be able to move up and down relative to the bottle body 5. This also places requirements on the sealing between the infusion tube 11 and the bottle body 5. Therefore, as shown in Figure 8, in one embodiment, a sealing assembly is provided between the fitting 7 and the infusion tube 11. The sealing assembly includes a docking portion 901, a sealing member 14, and a pressing member 15.

[0070] Among them, the docking part 901 is arranged at the upper end of the cap 9, and the docking part 901 is formed by the upward extension of the cap 9, and a mounting groove is provided on the docking part 901; the sealing part 14 is arranged in the mounting groove, and the sealing part 14 is a sealing ring, which is used to seal the infusion tube 11; the pressing part 15 is arranged above the sealing part 14, which is used to press the sealing part 14 in the mounting groove; the matching part 7 is threadedly mounted on the outer periphery of the docking part 901, and the pressing part 15 is fixed to the docking part 901.

[0071] In the sealing assembly, the movement of the infusion tube 11 relies on the sealing member 14 to achieve reliable sealing, thereby ensuring the normal use of the medicine feeding function.

[0072] 1 , 9 and 10 , in one embodiment, the atomizing inhalation device further includes a liquid storage structure, which includes a lower shell 4 , a drive assembly, a bottle 5 and a window 8 .

[0073] The lower shell 4 in the second liquid storage structure is roughly cylindrical and is arranged below the upper shell 1, which will not be described in detail here.

[0074] The drive assembly is located above the lower housing 4 and includes a vertically movable tube rack 10 and an infusion tube 11 extending through the rack. When the rack 10 drives the infusion tube 11 downward, it draws the medication from the bottle 5 and delivers it to the atomizer module 2. When the rack 10 drives the infusion tube 11 upward, it squeezes the medication and releases it outward through the atomizer module 2. This is conventional technology.

[0075] The bottle body 5 is disposed in the lower shell 4 . The bottle body 5 is similar to a mallet-shaped structure and includes a liquid storage portion 501 and a long neck 502 extending upward from the liquid storage portion 501 .

[0076] The liquid reservoir 501 is used to store medication, and its outer diameter is larger than that of the long neck 502 to meet medication filling requirements. Furthermore, at least the liquid reservoir 501 is made of a transparent material. For example, the liquid reservoir 501 alone, or both the liquid reservoir 501 and the long neck 502, are made of transparent plastic, making it easier for the user to observe the real-time status of the medication in the bottle.

[0077] The extended neck 502 is used to extend the height of the bottle body 5, ensuring that the liquid storage portion 501 is always within the visible range of the viewing window 8, thereby preventing the spring 12 from obstructing the liquid storage portion 501 and obstructing the user's view. In addition, the bottle body 5 is connected to the drive assembly via the extended neck 502. Specifically, the extended neck 502 is fixedly engaged with the pipe frame 10 (the engaging structure is not limited; for example, refer to the connection between the nozzle housing 3 and the exposed section 102) and moves synchronously therewith, thereby transporting the medicine in the bottle body 5 to the atomization module 2 and releasing it outward.

[0078] The viewing window 8 is provided on the side wall of the lower shell 4 and corresponds to the position of the liquid storage portion 501 , so that the user can observe the medicine in the bottle 5 .

[0079] The present invention provides a viewing window 8 on the lower shell 4 and utilizes an elongated neck 502 to extend the height of the bottle body 5, ensuring that the liquid storage portion 501 is always within the visible range of the viewing window 8. This facilitates the user's observation of the remaining amount and status of the medicine in the bottle body 5, thereby improving ease of use. Furthermore, compared to the first liquid storage structure, since the bottle body 5 moves up and down synchronously with the infusion tube 11, there is no need for a seal reinforcement design on the bottle body 5, resulting in a simpler structure and lower costs.

[0080] 10 and 11 , in one embodiment, the bottle body 5 is a double-layer structure, including an inner bag layer 5 a and an outer covering layer 5 b.

[0081] The inner bag layer 5a is flexible and is used to fill the medicine. The inner bag layer 5a can be made of flexible transparent plastic such as TPE, PVC, PP, etc. The thickness of the inner layer is about 1 / 8 of the outer bag layer, and it can be deformed and squeezed under the action of air pressure difference to squeeze the medicine.

[0082] The outer layer 5b is disposed outside the inner bag layer 5a. The outer layer 5b is hard and is used to protect the inner bag layer 5a. For example, the outer layer 5b can be made of acrylic or a hard transparent plastic such as PC, PMMA, PS, etc., so as to ensure that the outer layer 5b has a certain hardness and rigidity to meet the requirements of fixing the bottle body 5.

[0083] Compared to the prior art, the liquid storage structure of the present application eliminates the aluminum can enclosing the bottle body 5 and the corresponding piercing member (not shown; in the prior art, the piercing member is located on the inner wall of the lower shell 4 and is used to pierce the bottom of the aluminum can). This simplifies the internal design of the lower shell 4 and reduces production costs. The bottle body 5 is particularly suitable for situations where the long-term isolation and protection of the aluminum can are not required and the medicine needs to be used quickly due to its timeliness.

[0084] 8 and 12 , in one embodiment, the cap 9 is provided with a piercing portion 902 extending toward the interior of the bottle body 5. The piercing portion 902 is generally tubular and serves to guide the insertion of the infusion tube 11, thereby improving the stability of the infusion tube 11 during movement. Furthermore, the piercing portion 902 seals the bottle body 5, preventing leakage or deterioration of the medication.

[0085] Furthermore, a hose 16 is provided below the puncture portion 902. The hose 16 can be sealedly connected to the puncture portion 902. This design effectively solves the problem that the infusion tube 11 cannot absorb the medicine at the bottom of the bottle in the later stage. The flexibility of the hose 16 enables it to move flexibly within the bottle body 5. The infusion tube 11 can absorb the medicine in the bottle through the hose 16, which in turn increases the liquid absorption depth of the infusion tube 11, ensures that the medicine in the bottle can be fully utilized, and reduces unnecessary waste of medicine.

[0086] Alternatively, the hose 16 is connected to the puncture portion 902 via a dotted line. When the infusion tube 11, which passes through the cap, passes through the puncture layer, the hose 16 can be sealed around the lower end of the infusion tube 11 and separated from the hose 16 under the action of the puncture pressure. This design can also solve the problem of the infusion tube 11 being unable to draw medicine from the bottom of the bottle in the future. The difference is that the hose 16 can be separated from the puncture portion 902, thereby preventing the hose 16 from being blocked by debris from the puncture layer. Moreover, the hose 16 is sealed around the lower end of the infusion tube 11, allowing for a wider range of movement without being restricted by the infusion tube 11.

[0087] Furthermore, a configuration block (not shown) is provided at the lower end of the hose 16 , so that the hose 16 can better contact the medicine in the bottle 5 under the action of gravity.

[0088] 1 , 13 and 14 , in one embodiment, the atomizing inhalation device further includes a driving assembly, which includes a tube rack 10 , an infusion tube 11 , a spring 12 and a rotating body 13 .

[0089] The tube rack 10 is arranged in the upper shell 1; the infusion tube 11 is passed through the tube rack 10, and its lower end extends into the bottle body 5 and contacts the medicine; the spring 12 is arranged below the tube rack 10; the rotating body 13 is sleeved on the outer circumference of the spring 12, and the tube rack 10 rotates synchronously with the rotating body 13 and can move up and down relative to the rotating body 13.

[0090] The driving assembly has two working states: in the first working state, the infusion tube 11 moves downward relative to the bottle body 5 to extract the medicine in the bottle body 5 to the atomization module 2; in the second working state, the infusion tube 11 moves upward relative to the bottle body 5 to squeeze the medicine at the atomization module 2 and release it outward.

[0091] The driving assembly operates as follows: When the infusion tube 11 moves downward, the flow channel within the associated flow-guiding member 201 becomes vacuum-free, drawing the medicine from the bottle 5 into the flow-guiding member 201 under the negative pressure. When the infusion tube 11 moves upward, a one-way valve (not shown) at the top of the tube 11 forces the medicine inside the flow-guiding member 201 into the atomizing unit 204, where it is subsequently released as a soft mist. This is prior art and will not be elaborated upon here.

[0092] 13 to 16 , in one embodiment, a plurality of support plates 106 are provided at intervals on the inner top of the upper housing 1 , and an actuator 17 is provided between the support plates 106 and the rotating body 13 ;

[0093] The actuator 17 has two positions: in the first position, pressing the actuator 17 can release the restriction on the tube rack 10, and under the drive of the spring 12, the tube rack 10 and the infusion tube 11 move upward synchronously; in the second position, rotating the rotator 13 can drive the tube rack 10 and the infusion tube 11 to move downward synchronously, and at the same time, the actuator 17 is reset to restrict the tube rack 10 again.

[0094] The first position of the actuator 17 is an eccentric state, and the second position is a concentric state. Simply put, in the eccentric state, the actuator 17 presses against the tube holder 10, preventing it from moving upward. Pressing the actuator 17 moves the actuator 17 to the concentric state, whereupon the tube holder 10, driven by the spring 12, can move the infusion tube 11 upward. In the concentric state, the user rotates the lower housing 4, which in turn causes the rotator 13 to rotate, causing the tube holder 10 to rotate as well. Due to the action of the spring 12, the tube holder 10 remains in contact with the outer periphery of the through-cavity 101. A spiral guide structure (not shown) is provided between the two. This spiral guide structure allows the tube holder 10 to rotate and move downward. Simultaneously, an inclined guide structure (not shown) is provided between the actuator 17 and the rotator 13. As the tube holder 10 rotates downward, the actuator 17 gradually retracts and resets, until it again presses against the tube holder 10. This is prior art and will not be described in detail here.

[0095] Referring to Figures 14 to 16, in a preferred embodiment, a resistance slope 1061 is provided on the lower end surface of the support plate 106. The resistance slope 1061 is inclined downward from the inner edge of the lower end surface of the support plate 106, or the resistance slope 1061 is inclined downward from the middle of the lower end surface of the support plate 106, so as to increase the resistance of the pressing actuator 17 and prevent waste of medicine caused by accidental touch.

[0096] For example, the angle between the resistance slope 1061 and the horizontal plane is 3°-6°. If the angle is less than 3°, the resistance effect of pressing is not obvious. If the angle is greater than 6°, pressing becomes difficult and the operation is inconvenient. Preferably, the angle between the resistance slope 1061 and the horizontal plane is 4°-5°, and the angle of 5° is particularly effective.

[0097] As shown in Figures 3 and 16 , a button 18 is provided on the sidewall of the upper housing 1 , which is connected to the actuator 17 . A protective cover 19 is provided on the nozzle housing 3 to prevent impurities from entering and potentially clogging or contaminating the atomizer module 2 . A side cover 1901 is provided at the bottom of the protective cover 19 , covering the button 18. Together with the resistance ramp 1061 , this provides a dual protection against accidental touches, preventing medication waste.

[0098] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limiting the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the invention without departing from the principles and purpose of the present invention. All such changes shall fall within the scope of protection of the claims of the present invention.
