Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical devices, in particular to an atomization device. Background Art
[0002] Chronic obstructive pulmonary disease (COPD) is a common chronic disease characterized by airflow obstruction, including chronic bronchitis or emphysema, which can progress to cor pulmonale and respiratory failure. COPD is associated with an abnormal inflammatory response to harmful gases and particles, resulting in high rates of disability and mortality. The global prevalence of COPD in people over 40 years old is as high as 9% to 10%.
[0003] Pulmonary / nasal inhalation is an effective treatment for chronic obstructive pulmonary disease (COPD), characterized by targeted, high efficacy, rapid results, and minimal toxic side effects. Furthermore, pulmonary or nasal inhalation is frequently used in the treatment of respiratory diseases such as influenza and asthma. In the pharmaceutical field, a nebulizer device for delivering pharmaceutical compounds is commonly used for pulmonary or nasal inhalation. A nebulizer device contains the pharmaceutical compound, which is then drawn into the airways by the user's inhaled airflow, where it acts on the airways and lungs.
[0004] Traditional mechanical atomizers use a pre-compression reset member to eject a specified volume of liquid from a fluid channel through a nozzle to the outside to produce an aerosol. However, this type of atomizer usually requires the user to manually rotate the upper and lower shells of the atomizer to add the liquid medicine from the bottle to the nozzle. During this process, the user needs to use both hands to rotate the atomizer to pre-compress the reset member, and then press a button to trigger the pre-compression reset member to obtain an aerosol. The entire operation process is relatively complicated, making it difficult to release the aerosol quickly, and the pre-compression reset member must be used with both hands, which seriously affects the convenience of using the device.

DETAILED DESCRIPTION
[0032] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the 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 to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.
[0033] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.
[0034] See also Figure 1 and Figure 2 As shown, the utility model discloses an atomizing device, comprising an upper shell 1, a lower shell 2, a reset member 3 and an atomizing mechanism 4.
[0035] The upper shell 1 is generally T-shaped, with a first cavity 11 and a second cavity 12 disposed therein. The first cavity 11 is located above the second cavity 12, and the two are coaxially connected and arranged. In this application, the diameter of the first cavity 11 is smaller than the diameter of the second cavity 12. The first cavity 11 is used to install the atomization mechanism 4, and the second cavity 12 is used to install the lower shell 2.
[0036] In addition, a finger bracket 13 is provided on the outer side of the upper shell 1. The finger bracket 13 can be integrally formed on both sides of the upper shell 1, so that the user's index finger and middle finger can be buckled thereon for easy use.
[0037] The lower shell 2 is a cylindrical structure adapted to the upper shell 1, and is slidably disposed within the second cavity 12. The lower shell 2 moves in a manner similar to a syringe, and can move closer to or further away from the atomizing mechanism 4, thereby realizing a spray function. In the present application, the lower shell 2 includes a first half shell 21 and a second half shell 22 that are detachably connected, wherein the first half shell 21 is located above the second half shell 22, and the two are connected to form a space for accommodating the liquid storage bottle 5. Because the first and second half shells 21 and 22 are separable, when the liquid in the original liquid storage bottle 5 is exhausted, the second half shell 22 is separated from the first half shell 21, and a new liquid storage bottle 5 can be quickly replaced. The operation is convenient and efficient, and can effectively save medication costs.
[0038] The reset member 3 is arranged between the upper shell 1 and the lower shell 2, and its telescopic direction is consistent with the sliding direction of the lower shell 2, and is used to provide elastic force for resetting the lower shell 2. In this application, the reset member 3 is preferably a spring, which is easy to assemble and has good elastic control effect.
[0039] The atomizing mechanism 4 is disposed in the first cavity 11 and connected to the liquid storage bottle 5, and is used to pump the liquid in the liquid storage bottle 5 and release it after atomizing it. In the present application, the atomizing mechanism 4 includes a flow-guiding member, an infusion tube passing through the flow-guiding member, and an atomizing chip (not shown) disposed on the top of the flow-guiding member, wherein the atomizing chip is connected to the liquid storage bottle 5 via the infusion tube. The working principle of the atomizing mechanism 4 is the existing technology and is only briefly described here: when the infusion tube moves downward, the liquid in the liquid storage bottle 5 will be pumped into the flow-guiding member, and when the infusion tube moves upward, the liquid in the flow-guiding member will be squeezed to the atomizing chip and released outward in the form of mist droplets.
[0040] The use process of the atomizer device of this application is as follows:
[0041] 1. Remove the second half shell 22 of the lower shell 2 and select the liquid storage bottle 5 with a specific function;
[0042] 2. Install the liquid storage bottle 5 into the first half shell 21 and connect the atomizing mechanism 4 to the liquid storage bottle 5 (i.e., insert the infusion tube into the bottle). Then install the second half shell 22 and fix the liquid storage bottle 5 in the lower shell 2.
[0043] 3. Place your index and middle fingers on the finger bracket 13 of the upper shell 1, press the bottom end of the lower shell 2 with your thumb, and cooperate with the reset member 3 to make it move back and forth, so that the liquid in the liquid storage bottle 5 can be pumped and released outward after atomization.
[0044] See also Figure 2As shown, in some embodiments, the bottom of the first half shell 21 is provided with a first connection surface 211, and correspondingly, the top of the second half shell 22 is provided with a second connection surface 221, which can be formed by an upward extension of the upper end of the second half shell or by an outward depression of its inner wall. In the present application, the first connection surface 211 can be formed by an inward depression of the surface of the first half shell 21, and the second connection surface 221 can be formed by an outward depression of the inner wall of the second half shell 22. The two can be fixed by interference or by threading, thereby achieving a quick disassembly function and facilitating the replacement of the liquid storage bottle 5.
[0045] Furthermore, the length of the liquid storage bottle 5 is greater than that of the first half shell 21. This allows the second half shell 22 to be separated from the first half shell 21, partially exposing the liquid storage bottle 5, thereby facilitating its removal. Furthermore, the length of the liquid storage bottle 5 is less than or equal to the length of the lower shell 2. This allows the first and second half shells 21, 22 to be connected, clamping the liquid storage bottle 5 within the lower shell 2, ensuring a secure installation.
[0046] See also Figure 2 As shown, in some embodiments, a first limiting structure is provided between the upper shell 1 and the lower shell 2 to limit the sliding distance of the lower shell 2, ensure the consistency of the spray dosage, and avoid damage to the atomization mechanism 4 due to overtravel. In the present application, the first limiting structure includes a limiting groove 23 and a limiting block 6. The limiting groove 23 is provided on the side wall of the lower shell 2. For example, there are two limiting grooves 23, which are symmetrically distributed on the top of both sides of the first half shell 21; the limiting block 6 passes through the side wall of the upper shell 1 and extends into the limiting groove 23. The limiting block 6 slides with the limiting groove 23 to control the sliding distance of the lower shell 2.
[0047] Still like Figure 2 As shown, in some embodiments, a second limiting structure is provided between the upper shell 1 and the lower shell 2, and its function is the same as that of the first limiting structure, and is also used to limit the sliding distance of the lower shell 2, which has a dual protection function. In the present application, the second limiting structure includes an upper ring portion 14 and a lower ring portion 24. Among them, the upper ring portion 14 is arranged at the inner top of the upper shell 1, and it can be formed by extending downward from the first cavity portion 11; the lower ring portion 24 is arranged at the upper end of the lower shell 2, and it can be integrally formed with the lower shell 2. In this limiting structure, the upper ring portion 14 and the lower ring portion 24 are arranged relative to each other up and down, and the distance between the two is equal to the sliding distance of the lower shell 2. When the upper ring portion 14 conflicts with the lower ring portion 24, the lower shell 2 can be restricted from continuing to slide, thereby playing a limiting role.
[0048] Furthermore, in addition to the limiting function, the upper ring portion 14 and the lower ring portion 24 can also be used as a mounting seat for the reset member 3. Specifically, one end of the reset member 3 is sleeved on the upper ring portion 14, and the other end is sleeved on the lower ring portion 24, so as to facilitate the assembly of the reset member 3 and play a certain guiding role in the extension and retraction of the reset member 3.
[0049] In some embodiments, the sliding distance of the lower shell 2 is 10 mm to 20 mm. If the sliding distance is less than 10 mm, the short stroke will result in insufficient spray dosage, affecting the atomization treatment effect. If the sliding distance is greater than 20 mm, the excessively long stroke will make it inconvenient to press the lower shell 2 with the thumb, affecting the comfort of operation. Preferably, the sliding distance of the lower shell 2 can be 12 mm to 16 mm.
[0050] In some embodiments, at least the second half 22 of the lower housing 2 is transparent, allowing the user to observe the remaining liquid in the liquid storage bottle 5 through the second half 22 and determine whether it needs to be replaced. In the present application, the first half 21 is made of an opaque material to minimize the adverse effects of light on the liquid in the liquid storage bottle 5. The second half 22 can be made of a transparent plastic to achieve a partial visual function.
[0051] In some embodiments, a concave surface 131 is provided on the finger support 13 to better engage with the index finger and middle finger of the user, thereby achieving anti-slip and positioning effects and facilitating the pressing operation.
[0052] In some embodiments, the flow rate of the spray released by the atomization mechanism 4 is less than 5 m / s, for example, maintained between 1 m / s-4 m / s, between 0.8 m / s-2 m / s or basically constant, and at least 70% of the droplets in the spray have an average particle size of 3 μm-8 μm, preferably an average particle size of 3 μm-5 μm, so that the spray can roughly cooperate with the human body's inhalation action and then be effectively inhaled into the user's body.
[0053] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limiting the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the present invention.
