Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical devices, in particular to a lower shell component and a soft mist 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] Currently, most medical nebulizers on the market are disposable. Their integrated housing design prevents easy replacement of the internal medicine bottles. For patients requiring multiple medications, they need multiple nebulizers, which is inconvenient to carry and manage. In particular, once the medication in the bottle is consumed, the nebulizer must be discarded and repurchased, increasing medication costs and harming the environment.
[0005] Based on the above problems, the present application improves the charging part of the atomizing device and proposes a new lower shell assembly. Utility Model Content

DETAILED DESCRIPTION
[0034] 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.
[0035] 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.
[0036] See also Figures 1 to 3 As shown, the utility model discloses a lower shell assembly, which includes a rotating body 1, an elastic arm 2 and a lower shell 3.
[0037] The rotating body 1 is a circular tube structure with two ends connected, and its internal space is configured to accommodate the target bottle 4. Figure 5 As shown, in this application, the rotating body 1 can be connected to the target bottle body 4 through the built-in pipe rack unit 6, so that the target bottle body 4 is accommodated in its internal space. The pipe rack unit 6 and the target bottle body 4 should be detachable to facilitate replacement. As an example, the pipe rack unit 6 and the target bottle body 4 can be fixedly connected by means of snap fasteners, threads, etc.
[0038] In addition, the rotating body 1 is provided with an avoidance hole 11 to realize the avoidance function. Specifically, when the elastic arm 2 is pressed and deflected inward, the avoidance hole 11 can provide space for the outer protrusion 21 to ensure that it can be smoothly received in the hole to prevent interference problems. Figure 1 and Figure 2 As shown, in the present application, there are two avoidance holes 11 , which are symmetrically distributed on both side walls of the rotating body 1 .
[0039] The elastic arm 2 is a strip-shaped structure, mounted on the sidewall of the rotating body 1. It is typically made of elastic metal or plastic, enabling radial displacement and resetting of the rotating body 1. In this application, two elastic arms 2 are provided to form a balanced and stable locking connection with the lower housing 3. Preferably, the elastic arm 2 is integrally formed with the rotating body 1, with a portion of the elastic arm 2 extending into the avoidance hole 11.
[0040] In addition, the elastic arm 2 is provided with an outer protrusion 21 extending outward from the avoidance hole 11, and the outer protrusion 21 is used to cooperate with the inner protrusion 31 on the inner side of the lower shell 3 to form a locking structure, thereby realizing the connection and locking function between the rotating body 1 and the lower shell 3. Figure 2 As shown, in the present application, the upper end surface of the outer protrusion 21 is a plane, and the plane extends to the outside of the side wall of the rotating body 1 to form a supporting portion that contacts the inner protrusion 31 of the lower shell 3.
[0041] The lower shell 3 is a cylindrical structure with an open top, and an inner convex portion 31 and a button portion 32 are respectively provided on its side walls. The inner convex portion 31 is located inside the side wall of the lower shell 3 and is used to cooperate with the outer convex portion 21 of the elastic arm 2 to form a locking structure to achieve the connection function between the rotating body 1 and the lower shell 3. Figure 3 As shown, in the present application, the lower end surface of the inner convex portion 31 is also a plane so as to contact and abut against the upper end surface of the outer convex portion 21 .
[0042] The button portion 32 is located outside the side wall of the lower shell 3, and its position must correspond to the outer protrusion 21 of the elastic arm 2, so as to press and control the deformation of the elastic arm 2 to achieve the unlocking function. Figure 1 and Figure 2As shown, in the present application, one end of the button portion 32 is integrally formed with the lower shell 3 , and the other end is located outside the outer protrusion 21 , and the button portion 32 protrudes from the surface of the lower shell 3 for pressing operation.
[0043] See also Figures 1 to 3 As shown, when assembling the lower shell assembly, the lower shell 3 is aligned with the rotating body 1 and inserted therein until the outer protrusion 21 of the elastic arm 2 contacts the inner protrusion 31 of the lower shell 3 to form a locking structure, thereby realizing the functions of quick connection and locking. At this time, the lower shell 3 is sleeved on the outer periphery of the rotating body 1, and the button portion 32 is located outside the outer protrusion 21. When disassembling the lower shell assembly, the button portion 32 is pressed, and the elastic arm 2 drives the outer protrusion 21 to deflect radially inward, causing the outer protrusion 21 to separate from the inner protrusion 31, thereby unlocking the locking structure. The lower shell 3 is then removed from the rotating body 1, exposing the target bottle body 4 accommodated in the rotating body 1, and the replacement operation can be carried out.
[0044] The detachable design of the lower shell assembly makes the soft mist device reusable. Patients can quickly change dressings by simply removing the lower shell 3 from the rotating body 1, making operation convenient and efficient, and effectively reducing patients' treatment costs. In addition, the lower shell assembly uses a locking structure on both sides, where the outer protrusion 21 and the inner protrusion 31 abut each other, forming a stable and reliable connection.
[0045] See also Figure 2 and Figure 3 As shown, in some embodiments, a limit block 12 is provided on the side wall of the rotating body 1. The limit block 12 is located above the outer protrusion 21 and is used to limit the upward movement of the inner protrusion 31, so that the lower shell 3 is always kept in place during assembly to avoid affecting the formation of the locking structure.
[0046] Furthermore, the lower end of the limit block 12 cooperates with the side wall of the rotating body 1 to form a concave corner 13, which is used to accommodate the inner convex portion 31 and also plays a certain avoidance role so that the inner convex portion 31 can move smoothly.
[0047] See also Figure 3 As shown, in some embodiments, the outer protrusion 21 is provided with a guide bevel 211 extending from the surface of the elastic arm 2 toward its outer side surface, and the included angle between the guide bevel 211 and the horizontal plane is 50°-60°. If the included angle is less than 50°, the guiding ability of the guide bevel 211 is reduced, resulting in increased resistance during assembly of the lower shell 3; if the included angle is greater than 60°, the thickness of the elastic arm 2 near the outer protrusion 21 increases, affecting its own elasticity. In the present application, when the included angle between the guide bevel 211 and the horizontal plane is 50°-60°, the lower shell assembly is relatively good in both assembly and operation.
[0048] See also Figure 1 and Figure 4As shown, in some embodiments, a first protrusion 22 is provided at the bottom of the elastic arm 2, and a second protrusion 33 is provided on the side wall of the lower shell 3 to interfere with the first protrusion 22, thereby further enhancing the connection between the rotating body 1 and the lower shell 3. In the present application, the first protrusion 22 and the second protrusion 33 are both small arc-shaped structures, and the first protrusion 22 is located below and to the side of the second protrusion 33.
[0049] See also Figure 2 As shown, in some embodiments, the lower shell 3 is made of an opaque material to reduce the exposure of light to the medicine in the bottle, which helps to maintain the stability and effectiveness of the medicine. However, at least one window 34 is provided on the side wall of the lower shell 3 for the patient to observe the internal situation of the lower shell 3, so as to make a judgment on whether the target medicine bottle needs to be replaced. In the present application, there are two windows 34, which are symmetrically distributed on both sides of the lower shell 3 so that the patient can observe from either side, thereby improving convenience. Preferably, the window 34 is a strip structure, and the length direction of the window 34 is consistent with the length direction of the lower shell 3, so as to improve its visual range.
[0050] Furthermore, the target bottle body 4 is made of a transparent material, such as a transparent plastic such as TPE or PP, to ensure drug storage safety. The target bottle body 4 includes a liquid reservoir 41 and an elongated neck 42 extending upward from the liquid reservoir 41. The elongated neck 42 increases the height of the target bottle body 4, ensuring that the liquid reservoir 41 is always within the visible range of the viewing window 34, making it easier for the patient to observe the remaining amount and status of the drug in the bottle.
[0051] See also Figure 5 As shown, the present invention also discloses a soft mist device, such as a nasal sprayer, which includes the above-mentioned lower shell assembly. By making the lower shell 3 detachable, it is convenient for patients to replace the medicine bottle by themselves, and the soft mist device can be reused, thereby reducing the cost of medication and improving convenience.
[0052] In some embodiments, the soft mist device further includes an upper shell 5, a tube support unit 6, and an atomizing mechanism 7. The upper shell 5 is disposed above the lower shell 3 and is rotatably connected to the rotating body 1; the tube support unit 6 is disposed within the rotating body 1 and is detachably connected to the target bottle 4; the atomizing mechanism 7 is disposed within the upper shell 5 and movably connected to the tube support unit 6. The atomizing mechanism 7 is configured to pump the liquid in the target bottle 4 and release it after atomizing it.
[0053] During use, one hand holds the upper housing 5, and the other hand rotates the rotating body 1 through the lower housing 3, causing the tube rack unit 6 to move up and down with the target bottle 4. The tube rack unit 6 moves downward to cooperate with the atomizing mechanism 7 to pump the liquid in the target bottle 4, and moves upward to cooperate with the atomizing mechanism 7 to atomize the liquid and release it outward. This is a prior art and will not be described in detail.
[0054] 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.
