Description

[0001] This application is a divisional application of Chinese patent application CN202311651993.4, filed on December 5, 2023, entitled "A medicine bottle mounting structure and a soft mist device". Technical Field

[0002] This invention relates to the field of medical devices, and more particularly to a medicine bottle mounting structure and a soft mist device. Background Technology

[0003] Medical soft fog devices are mainly used to treat various respiratory diseases. The principle is to atomize the liquid medicine into tiny particles, and the medicine enters the respiratory tract and lungs through inhalation, thereby achieving the purpose of painless, rapid and effective treatment.

[0004] In the US patent with publication number US8733341 B2, the soft mist device uses a container 3 that always moves up and down synchronously with the delivery pipe 9 to deliver the medicine. This movable container makes it difficult for users to observe the remaining medicine in the container in real time, especially when the container is in the upward position (i.e., in the spraying state). Due to the obstruction of the spring 7 inside the soft mist device, the user cannot observe the container, which seriously affects the user experience.

[0005] Therefore, this application modifies the mounting structure of the medicine bottle to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a medicine bottle mounting structure and a soft mist device for fixing the position of the medicine bottle, so that the patient can easily observe the remaining amount of medicine in the bottle through the viewing window and make an appropriate judgment.

[0007] The objective of this invention is achieved through the following technical solution:

[0008] A medicine bottle mounting structure, comprising:

[0009] The lower housing has a cavity inside;

[0010] The bottle body is made of transparent material and is disposed within the cavity. A cap is provided at the mouth of the bottle body.

[0011] A spring seat is disposed above the bottle body, and the bottom surface of the spring seat abuts against the edge of the cap to confine the bottle body to the bottom region within the lower housing.

[0012] A viewing window is provided on the side wall of the lower housing, and the position of the viewing window corresponds to the position of the bottle body, so that the user can observe the remaining amount of medicine in the bottle through the viewing window.

[0013] In the above solution, the bottle position is fixed and a viewing window is provided on the side wall of the lower shell so that the user can observe the medicine in the bottle, so as to understand the usage, remaining amount, quality and safety of the medicine in the soft mist device, and ensure that the user receives accurate and safe treatment.

[0014] In some embodiments, a fitting member is provided above the cap, and the cap is fixed to the spring seat by interference through the fitting member.

[0015] In some embodiments, the cap is provided with an upwardly extending connecting portion;

[0016] The mating part is threaded onto the connecting part, and a groove is provided on the outer periphery of the mating part;

[0017] The inner wall of the spring seat is provided with a protrusion, which can be embedded in the groove to limit and fix the bottle body.

[0018] The above solution further enhances the reliability of bottle fixation. Furthermore, by using a mating component and a spring seat with interference fit, a quick assembly function between the bottle and the spring seat is achieved, facilitating the replacement of the medication.

[0019] In some embodiments, the connecting part is provided with a mounting groove, and a clamping member and a sealing ring are arranged sequentially from top to bottom in the mounting groove;

[0020] The clamping component is held and fixed by the connecting part and the mating part, and the clamping component is provided with a through hole coaxial with the sealing ring.

[0021] The sealing ring is pressed tightly to the bottom of the mounting groove by the clamping device, and the sealing ring is used to seal with the infusion tube that passes through the cap and extends into the bottle body.

[0022] The above solution solves the dynamic sealing problem during the raising and lowering of the infusion tube by setting a sealing structure, which can effectively prevent external gases or impurities from entering the inside of the bottle and contaminating the medicine.

[0023] In some embodiments, the cap is provided with a downwardly extending sealing portion;

[0024] The sealing part is a tubular structure with a puncture layer on its bottom surface, and at least part of the inner wall of the sealing part can be sealed with the infusion tube inserted into the bottle.

[0025] The above solution, by setting a sealing part, can seal the medicine in the bottle, and at the same time has a guiding function, which can improve the stability of the infusion tube movement.

[0026] In some embodiments, a flexible tube is provided at the bottom of the sealing portion, and the flexible tube extends to the inner bottom of the bottle.

[0027] The above solution solves the problem of the infusion tube being unable to draw medication from the bottom of the bottle later. By utilizing the flexibility of the tubing, it can move flexibly within the bottle, allowing the infusion tube to draw medication from the bottle. This indirectly increases the suction depth of the infusion tube, ensuring that the medication in the bottle can be fully utilized and reducing unnecessary waste of medication.

[0028] In some embodiments, a counterweight is provided at the end of the hose away from the seal.

[0029] The above solution adds a counterweight to the lower end of the tubing, so that the counterweight can move the tubing to the position where the medicine accumulates, whether the bottle is in a vertical or tilted position, ensuring that the medicine in the bottle can be drawn out by the infusion.

[0030] In some embodiments, a short-circuit line is provided between the hose and the sealing portion;

[0031] When the infusion tube penetrating the cap passes through the puncture layer, the tubing can be sealed onto the lower end of the infusion tube and separated from the tubing under the puncture pressure.

[0032] The above solution can also solve the problem of the infusion tube being unable to draw the medicine from the bottom of the bottle in the later stages, and can also effectively avoid the puncture layer fragments clogging the tubing. In addition, the tubing has a wider range of movement and is not restricted by the infusion tube.

[0033] In some embodiments, the cap is fastened to the bottle body with a snap fastener and a sealing gasket is provided between them for sealing.

[0034] In some embodiments, a rotating body is also provided in the cavity, and the rotating body rotates synchronously with the lower housing to drive the infusion tube extending into the bottle to rise or fall.

[0035] The outer wall of the spring seat is engaged and fixed to the rotating body.

[0036] The above solution connects the spring seat to the rotating body, thereby fixing the position of the spring seat and using it as the basis for fixing the bottle.

[0037] In some embodiments, the bottle body has a double-layer structure, and the bottle body includes:

[0038] Inner bag layer, the inner bag layer is used for filling medicine, and the inner bag layer is made of flexible material;

[0039] An outer layer, which covers the inner bag layer, is made of a rigid material.

[0040] A soft mist device includes the medicine bottle mounting structure described above.

[0041] The above solution enables users of soft fog devices to easily understand the usage, remaining quantity, quality, and safety of the medication inside the device, ensuring that users receive accurate and safe treatment.

[0042] In some embodiments, the soft mist device further includes a nozzle structure, the nozzle structure comprising:

[0043] Atomizing assembly, wherein the atomizing assembly is connected to an infusion tube extending into the bottle body;

[0044] A nozzle housing is fitted around the outer periphery of the atomizing assembly, and air inlets are symmetrically arranged on both sides of the nozzle housing;

[0045] Ventilation slots are disposed on the inner wall of the nozzle housing and are evenly spaced around the outer periphery of the atomizing component;

[0046] The air drawn in through the air inlet can mix with the medicine sprayed by the atomizing component to form a soft mist after passing through the ventilation slot.

[0047] The above solution solves the problem of poor airflow caused by the assembly of the atomizing component and / or nozzle housing due to tolerance by designing an air vent between the atomizing component and the nozzle housing. This ensures that the air drawn in from the air inlet can flow to the nozzle of the atomizing component and mix with the sprayed agent to form a soft mist.

[0048] Compared with the prior art, the beneficial effects of the present invention include at least the following: by modifying the infusion structure, the position of the bottle is fixed and remains stationary, and the user can clearly observe the medicine in the bottle through the viewing window in order to understand the usage, remaining amount, quality and safety of the medicine in the soft mist device, and ensure that the user receives accurate and safe treatment.

[0056] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided to make the invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0057] The terms used to express position and direction in this invention are illustrated with reference to the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this invention.

[0058] See Figure 1 and Figure 2 As shown, the present invention discloses a medicine bottle mounting structure, including a lower shell 1, a bottle body 2, a spring seat 3, and a viewing window 4.

[0059] like Figure 1 As shown, the lower housing 1 is roughly cylindrical, and its interior is provided with a cavity 101 for housing accessories such as the bottle body 2 and the spring seat 3 for the soft mist device.

[0060] In this application, the lower shell 1 is made of an opaque material to prevent direct light from shining into the medicine inside the bottle 2, which could cause the medicine to deteriorate or become ineffective. Preferably, the lower shell 1 can be made of opaque plastic injection molding to reduce its weight and production costs.

[0061] The bottle body 2 is located inside the cavity 101 of the lower shell 1. The bottle body 2 is made of a transparent material, such as transparent plastic or glass, to ensure that the medicine inside is visible.

[0062] In addition, such as Figure 2 As shown, a cap 5 is provided at the mouth of the bottle body 2. The cap 5 is used to seal the bottle body 2 and fix the position of the bottle body 2. Usually, the cap 5 is made of a hard material, such as an aluminum cap.

[0063] Or as Figure 1 As shown, the spring seat 3 is located above the bottle body 2 and its position is fixed inside the lower housing 1. It is usually used to support the actuator (i.e., spring, not labeled) of the soft mist device. This is prior art and will not be described here.

[0064] However, in this application, the spring seat 3 is also used to clamp the bottle body 2. Specifically, the bottom surface of the spring seat 3 abuts against the edge of the cap 5, forming a step-like stop structure, thereby restricting the bottle body 2 within the bottom area of ​​the lower housing 1, so that the bottom of the bottle body 2 abuts against the inner bottom of the lower housing 1, and the top of the bottom of the bottle body 2 abuts against the bottom surface of the spring seat 3. By clamping the bottle body 2, its freedom of movement in the height direction is restricted, thereby achieving a fixed effect.

[0065] like Figure 1 and Figure 4 As shown, the viewing window 4 is located on the side wall of the lower housing 1, and its position corresponds to the position of the bottle body 2. Both are located in the bottom area inside the lower housing 1, so that the user can observe the remaining amount of medicine in the bottle body 2 through the viewing window 4.

[0066] In this application, at least one window is provided on the side wall of the lower housing 1, and a viewing window 4 is disposed within the window. The viewing window 4 may also be made of transparent plastic. For example, there are two viewing windows 4, symmetrically distributed on both sides inside the lower housing 1.

[0067] See Figure 1 , Figure 2 and Figure 5 As shown, during assembly, the bottle mounting structure of this application involves inserting the bottle body 2 into the spring seat 3, ensuring the bottom surface of the spring seat 3 abuts against the edge of the cap 5. Then, the lower housing 1 is fitted until the inner bottom of the lower housing 1 abuts against the bottom of the bottle body 2, thus securing the bottle body 2. Medication delivery within the bottle body 2 is achieved through the infusion tube 9. In this application, the infusion tube 9 penetrates the cap 5 and extends into the bottle body 2. An actuator drives the infusion tube 9 to move up and down, drawing the medication from the bottle body 2 upwards to the nozzle structure. Throughout the process, the bottle body 2 remains in the bottom area within the lower housing 1. The user can clearly observe the medication within the bottle body 2 through the viewing window 4 to understand the usage, remaining quantity, quality, and safety of the medication in the soft mist device, ensuring accurate and safe treatment for the user.

[0068] Typically, the bottle 2, housed within the lower housing 1, is not removable, as it forms an integral structure with other components of the atomizing device (not shown) to ensure medication safety. However, in some other embodiments, the lower housing 1 and bottle 2 can be designed to be detachable, facilitating medication replacement or bottle 2 cleaning for the user; however, this process must be performed under the guidance of medical personnel.

[0069] In some embodiments, the lower housing 1 has a height of 60-80mm and a diameter of 20-30mm, which makes it convenient for users to hold and operate.

[0070] See Figure 1 As shown, in some embodiments, a mating part 6 is provided above the cap 5, and the cap is fixed to the spring seat 3 by interference through the mating part 6, thereby further enhancing the reliability of the bottle body 2. In addition, the interference relationship between the mating part 6 and the spring seat 3 enables the quick assembly of the bottle body 2 and the spring seat 3, facilitating the replacement of the medicine.

[0071] Specifically, the cap 5 is provided with an upwardly extending connecting part 501, which is generally cylindrical and may be threaded on its outer periphery. The mating part 6 may be a component similar to a screw cap, which is threaded onto the connecting part 501 to form an integral structure.

[0072] To ensure the connection and fixation between the mating part 6 and the spring seat 3, a groove 601 is provided on the outer periphery of the mating part 6, and correspondingly, a protrusion 301 is provided on the inner wall of the spring seat 3. In use, the protrusion 301 can be inserted into the groove 601 to fix the bottle body 2. The installation of the bottle body 2 is convenient and efficient, while also restricting the degree of freedom of the bottle body 2 in the radial direction, further improving the stability of the position of the bottle body 2.

[0073] See Figure 1 and Figure 2 As shown, in some embodiments, the connecting part 501 is provided with an installation groove 5011, which is coaxially arranged with the bottle mouth of the bottle body 2, and the mounting groove 5011 is provided with a pressing member 7 and a sealing ring 8 from top to bottom.

[0074] The sealing ring 8 is used to seal with the infusion tube 9 that penetrates the cap 5 and extends into the bottle body 2. The sealing ring 8 and the infusion tube 9 are dynamically sealed. Under the premise of ensuring smooth movement of the infusion tube 9, it can effectively prevent external gas or impurities from entering the interior of the bottle body 2 and contaminating the medicine.

[0075] The shape of the clamping component 7 is adapted to the mounting groove 5011 and is used to press the sealing ring 8 into the bottom of the mounting groove 5011. The outer periphery of the clamping component 7 has protruding side wings, which can be clamped and fixed by the connecting part 501 and the mating part 6. The clamping component 7 is provided with a through hole for the infusion tube 9 to pass through.

[0076] See Figure 2 As shown, in some embodiments, a downwardly extending sealing portion 502 is provided inside the cap 5. The sealing portion 502 is used to seal the medicine inside the bottle 2, and also has a guiding function, which can improve the stability of the movement of the infusion tube 9.

[0077] The sealing part 502 in this application has a tubular structure with a puncture layer 5021 on its bottom surface. Before the medication in the bottle 2 is used, the puncture layer 5021 seals it. Furthermore, at least part of the inner wall of the sealing part 502 can seal against the infusion tube 9 that extends into the bottle 2. Specifically, the sealing part 502 includes an upper tube section, a transition section, and a lower tube section connected in sequence. The diameters of the upper tube section and the transition section are both larger than the diameter of the infusion tube 9. The transition section has a frustum-shaped structure, with its diameter gradually decreasing from top to bottom. This allows the infusion tube 9 to be smoothly inserted into the lower tube section in conjunction with the upper tube section. The diameter of the lower tube section is equal to or slightly smaller than the diameter of the infusion tube 9. This allows the inner wall of the lower tube section to form a second seal with the infusion tube 9 after it passes through the puncture layer 5021, in addition to the sealing ring 8, further improving the sealing performance between the infusion tube 9 and the bottle 2.

[0078] See also Figure 2 As shown, in some embodiments, a flexible tube 10 is provided at the bottom of the sealing part 502. For example, one end of the flexible tube 10 is sealed to the sealing part 502 (not shown), and the other end of the flexible tube 10 extends to the inner bottom of the bottle body 2. This design effectively solves the problem that the infusion tube 9 cannot draw the medicine from the bottom of the bottle later. By utilizing the flexibility of the flexible tube 10, it can be moved flexibly to any position of the bottle body 2. The infusion tube 9 can draw the medicine in the bottle through the flexible tube 10, which indirectly increases the suction depth of the infusion tube 9, ensuring that the medicine in the bottle can be fully utilized and reducing unnecessary waste of medicine.

[0079] Furthermore, a counterweight 11 is provided at the end of the hose 10 away from the sealing part 502, which allows the counterweight 11 to move the hose 10 to the position where the medicine accumulates, whether the bottle 2 is in a vertical or tilted state, ensuring that the medicine in the bottle 2 can be drawn out by the infusion tube 9.

[0080] See Figure 3 As shown, in another embodiment, a break line 12 is provided between the tubing 10 and the sealing part 502. When the infusion tube 9 penetrating the cap 5 passes through the puncture layer 5021, the tubing 10 can be sealed and fitted onto the lower end of the infusion tube 9 and separated from the tubing 10 under the puncture pressure. This design can also solve the problem of the infusion tube 9 being unable to draw the medicine from the bottom of the bottle later. The difference is that the tubing 10 can be separated from the sealing part 502, thereby preventing fragments of the puncture layer 5021 from clogging the tubing 10. In addition, the tubing 10 is sealed and fitted onto the lower end of the infusion tube 9, allowing for a greater range of motion and not being restricted by the infusion tube 9.

[0081] See Figure 2As shown, in some embodiments, the cap 5 is snapped together with the bottle body 2. For example, a hook is provided on the inner side of the cap 5, and a groove is provided at the neck of the bottle body 2. The cap 5 and the bottle body 2 are fixedly connected by the cooperation of the hook and the groove. Furthermore, a sealing gasket 13 is provided between the cap 5 and the bottle body 2 for sealing. For example, the sealing gasket 13 is a V-shaped sealing gasket 13, which can form two seals after being squeezed by the cap 5 and the bottle body 2, greatly ensuring the sealing performance between the cap 5 and the bottle body 2.

[0082] See Figure 1 and Figure 5 As shown, in some embodiments, a rotating body 14 is also provided inside the cavity 101. The rotating body 14 rotates synchronously with the lower housing 1 and drives the infusion tube 9, which extends into the bottle 2, to rise or fall through a compression actuator, thereby realizing the function of drug delivery. The spring seat 3 is fixed to the rotating body 14 by snapping it into its outer wall, thereby fixing its own position and using it as the basis for fixing the bottle 2.

[0083] See Figure 2 As shown, in some embodiments, the bottle body 2 has a double-layer structure, including an inner bag layer 21 and an outer packaging layer 22.

[0084] The inner bag layer 21 is used for filling with medicine. The inner bag layer 21 can be made of medical-grade flexible materials such as PVC or PP, with TPE being the preferred material. Inner bag layers 21 made of this material are relatively soft and can deform and compress the medicine under negative pressure, thus achieving the delivery function. Furthermore, TPE material has extremely low gas permeability and is thermally stable, allowing for excellent medicine storage.

[0085] The outer layer 22 covers the inner bag layer. The outer layer 22 can be made of rigid materials such as glass, PC, PMMA, PS, etc., to protect the inner bag layer 21 and at the same time give the bottle body 2 a certain rigidity to prevent it from being clamped and deformed, thus affecting the fixing effect.

[0086] Compared with the prior art, the bottle body 2 of this application does not need to be moved, so its outer layer does not need to be designed with aluminum can protection, and the inner bottom of the corresponding underground shell 1 does not need to be designed with a puncture structure, which not only reduces the cost, but also simplifies the structure of the soft fog device.

[0087] See Figures 4 to 6 As shown, the present invention also discloses a soft mist device, including the above-mentioned medicine bottle mounting structure, which allows users to easily understand the usage, remaining amount, quality and safety of the medicine in the soft mist device, ensuring that users receive accurate and safe treatment.

[0088] like Figure 5 and Figure 6As shown, in some embodiments, the soft mist device further includes a nozzle structure, which includes an atomizing component 15, a nozzle housing 16, and a ventilation channel 17.

[0089] The atomizing component 15 is connected to the infusion tube 9 that extends into the bottle body 2. The atomizing component 15 is used to convert the liquid medicine input by the infusion tube 9 into fine medicine droplets.

[0090] The nozzle housing 16 is fitted around the outer periphery of the atomizing assembly 15 to protect the atomizing assembly 15 and to give the sprayed soft mist a certain mist pattern, i.e., to set a deflection angle. In addition, air inlets 1601 are symmetrically arranged on both sides of the nozzle housing 16. The high-speed airflow drawn in through the air inlets 1601 will collide and mix with the agent sprayed by the atomizing assembly 15, forming a very small micro-jet soft mist under the action of the "Rayleigh rupture" mechanism.

[0091] The ventilation groove 17 is provided on the inner wall of the nozzle housing 16 and is evenly spaced around the outer periphery of the atomizing component 15. This ensures that the air drawn in by the air inlet 1601 can flow to the nozzle of the atomizing component 15, and avoids airflow obstruction caused by the assembly of the atomizing component 15 and / or the nozzle housing 16 due to tolerance reasons.

[0092] When in use, the user presses their mouth against the nozzle housing 16 and inhales, then activates the soft mist device by pressing the button (not shown). The air drawn in through the air inlet 1601 passes through the ventilation slot 17 and mixes with the agent sprayed from the atomizing component 15 to form a soft mist.

[0093] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the invention without departing from the principles and spirit of the invention, and all such changes should fall within the protection scope of the claims of the present invention.
