Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] In this document, the components and elements described herein are not limited to a specific number. This is merely for ease of explanation and to provide a general understanding of the scope of this invention. Furthermore, the terms "a" or "an" may be used to describe the components and elements described herein, and such descriptions should be understood to include one or at least one, with the singular also including multiples.

[0038] In this document, the terms "comprising," "having," or any other similar terms are intended to cover non-exclusive inclusions. For example, a component or structure containing multiple elements is not limited to those listed herein, but may include other elements not expressly listed but which are generally inherent to the component or structure.

[0039] First, please refer to Figures 1 to 6 The oral inhalation drug delivery device provided in the preferred embodiment of this utility model includes a connection unit 10, an inhalation unit 20, a drug storage unit 30, and a control unit 40.

[0040] The assembly unit 10 includes a first housing 11 and a connecting pipe 12. The two opposite ends of the connecting pipe 12 are a first end 121 and a second end 122, respectively. The first end 121 of the connecting pipe 12 passes through the first housing 11 and communicates with the inside of the first housing 11, while the second end 122 of the connecting pipe 12 is exposed outside the first housing 11.

[0041] The inhalation unit 20 is detachably mounted on the second end 122 of the connecting tube 12.

[0042] The medicine storage unit 30 includes a medicine storage bottle 31, a one-way device 32, a sealing member 33, a medicine outlet 34, an atomizing plate 35, a rubber stopper 36, and a spring 37. The medicine storage bottle 31 is disposed inside the first housing 11 and is used to store liquid medicine. The two opposite ends of the tube shaft of the medicine storage bottle 31 are the third end 311 and the fourth end 312, respectively.

[0043] A one-way device 32 is provided on the third end 311 of the medicine storage bottle 31 to allow the medicine to enter the medicine storage bottle 31 during the medicine injection process and to prevent the medicine from leaking.

[0044] The sealing element 33 is installed on the fourth end 312 of the medicine storage bottle 31 to seal off the connection with the outside world.

[0045] One end of the medicine outlet 34 is inserted through the medicine storage bottle 31 and communicates with the inside of the medicine storage bottle 31, while the other end of the medicine outlet 34 is connected to the first end 121 of the connecting pipe 12, so that the connecting pipe 12 communicates with the inside of the medicine storage bottle 31 through the medicine outlet 34.

[0046] The atomizing plate 35 is disposed inside the drug outlet 34 and between the drug storage bottle 31 and the connecting tube 12;

[0047] The rubber stopper 36 is slidably disposed inside the medicine storage bottle 31, and when it moves, it can push the liquid medicine in the medicine storage bottle 31 toward the atomizing plate 35 located in the medicine outlet 34, so as to ensure that the liquid medicine can smoothly enter the atomizing plate 35, thereby realizing the atomization function, and avoiding gaps or stagnation between the liquid medicine and the atomizing plate 35.

[0048] Spring 37 is installed inside medicine bottle 31. One end of spring 37 is connected to rubber stopper 36, and the other end abuts against sealing member 33, and is used to apply elastic restoring force to rubber stopper 36.

[0049] The control unit 40 is detachably mounted on the first housing 11 via the connection structure 50 and is electrically connected to the atomizing plate 35 so that it can provide the necessary power or signal to the atomizing plate 35 when the control unit 40 is working, thereby realizing the atomization function.

[0050] Based on the above structural description, the specific usage steps of this utility model are as follows:

[0051] First, the inside of the medicine bottle 31 is hollow, and the spring 37 is not compressed, so the rubber stopper 36 is positioned near the medicine outlet. Next, the medicine is injected into the medicine bottle 31 via the one-way device 32. As the amount of medicine in the medicine bottle 31 increases, the medicine pushes the rubber stopper 36 to move, simultaneously compressing the spring 37, thus completing the injection. The amount of medicine in the medicine bottle 31 is a predetermined dose, for example, 100 milliliters (ml).

[0052] When a user uses the oral inhalation drug delivery device, the control unit 40 controls the nebulizer 35 to atomize a measured amount of medication. Simultaneously, as the medication is consumed, the spring 37 moves the medication, adjusting the volume of the medication in the reservoir 31. This ensures stable and precise delivery of the medication, guaranteeing consistent dosage and complete contact between the nebulizer 35 and the medication. This prevents gaps or air bubbles from forming during medication consumption, which could cause the nebulizer 35 to stop working. For example, if each nebulization involves 10 ml of medication, 10 nebulization sessions can be performed.

[0053] In addition, compared with traditional technology, this utility model reduces the number of solenoid valves and only uses the restoring force provided by spring 37 to appropriately pressurize the liquid medicine, so as to avoid excessive pressure of the liquid medicine and cause leakage of the atomizing plate.

[0054] Furthermore, the detailed structural design of this utility model is described below.

[0055] like Figure 2 , Figure 4 , Figure 5 As shown, the one-way device 32 includes a one-way valve 321 and a Luer cap 322. The one-way valve 321 is disposed inside the port of the medicine storage bottle 31 at the third end 311. The Luer cap 322 includes a connector 3221 and a sealing cap 3222. One end of the connector 3221 is disposed on the medicine storage bottle 31 at the third end 311; the sealing cap 3222 is detachably covered on the other end of the connector 3221.

[0056] The atomizing plate 35 is a long-sound atomizing plate, which is composed of piezoelectric ceramic and metal plate. The control unit 40 provides the power or signal required for the operation of the long-sound atomizing plate, so that the piezoelectric ceramic drives the metal plate to vibrate and realize liquid atomization, which is convenient for inhalation.

[0057] like Figure 2 , Figure 4 , Figure 5 As shown, the first housing 11 includes a first sidewall 111, a second sidewall 112 opposite to the first sidewall 111, a connecting wall 113 disposed between the first sidewall 111 and the second sidewall 112, and a slot 114 formed by the first sidewall 111, the second sidewall 112 and the connecting wall 113. The connecting wall 113 also spans between two adjacent end sides of the first sidewall 111 and the second sidewall 112.

[0058] like Figure 1 , Figure 2 As shown, the drug storage unit 30 is fixed to the first housing 11 using a suitable assembly method to ensure its stability and safety during use. In this example, the drug storage unit 30 is fixed to the first housing 11 using a limiting structure 60. Specifically, the limiting structure 60 has a buckle 61, which is provided on the connecting wall 113 and extends into the first housing 11, and can hook onto the drug storage unit 30, thereby making the drug storage unit 30 stably and securely fixed to the first housing 11 without shaking and without being detachable.

[0059] like Figures 1 to 4As shown, the inhalation unit 20 includes a mouthpiece 21, a mouthpiece connector 22, and a quick-release assembly 23. The mouthpiece 21 is a common ergonomically designed mouthpiece, primarily curved or elliptical in shape, conforming to the user's mouth for a comfortable experience. Furthermore, the mouthpiece 21 has an airflow channel 212, serving as the path for delivering the atomized medication. The airflow channel 212 has a narrower inner diameter and a wider outer diameter to reduce resistance to the flow of the atomized medication and increase its smoothness. Additionally, the side wall of the mouthpiece 21 has an opening 211 of appropriate size.

[0060] One end of the nozzle connector 22 is mounted on the nozzle 21 and connected to one side of the air duct 212, while the other end of the nozzle connector 22 is detachably mounted on the second end 122 of the connecting tube 12.

[0061] Furthermore, in this example, the suction nozzle 21 and the suction nozzle tube 22 are integrally formed, and the suction unit 20 also has an outer cover 24 that is detachably provided on the suction nozzle 21 to prevent direct contact with the outside world when not in use.

[0062] The quick-release assembly 23 is detachably located at the connection point between the nozzle guide tube 22 and the connecting tube 12. Specifically, as follows... Figure 2 , Figure 3 , Figure 4 As shown, the quick-release assembly 23 has a buckle 231, which is set to correspond to the contour shape of the opening of the connecting tube 12. The buckle 231 is normally fixed to the outer wall of the connecting tube 12. More specifically, the buckle 231 includes a base 2311, a pair of latching arms 2312, and a button 2313. The base 2311 has a predetermined length, and the latching arms 2312 extend from both ends of the base 2311 in the same direction. The extension direction of the latching arms 2312 is perpendicular to the length direction of the base 2311. Accordingly, the base 2311 and the latching arms 2312 form a U-shaped structure or a C-shaped structure.

[0063] Button 2313 is located on the opposite side of the base 2311 from the extending direction of the latching arm 2312. When the nozzle tube 22 is sleeved on the connecting tube 12, button 2313 is embedded in the opening 211, and a portion of the free end of button 2313 is exposed outside the nozzle 21 through the opening 211.

[0064] Accordingly, the suction unit 20 adopts a quick-release design for easy installation and removal. Simply put, when the nozzle connector 22 is fitted onto the connecting tube 12, the snap fastener 231 secures the connecting tube 12 and presses down on the fitted nozzle connector 22, ensuring a stable installation of the suction unit 20 and improving the sealing of the connection. Next, when the suction unit 20 needs to be replaced or cleaned after use, pressing the button 2313 causes the snap fastener 231 to elastically deform, meaning the latch arm 2312 opens outwards and disengages from the connecting tube 12, thus easily removing the suction unit 20. Finally, after cleaning the connection area, a new suction unit 20 is installed to ensure the hygiene and proper functioning of the equipment.

[0065] The control unit 40 includes a second housing 41, a control module 42, and a battery 43. The second housing 41 is used to house the control module 42 and the battery 43. Its shape is usually designed as an L-shaped rectangular block structure, but it can also be designed as other geometric structures according to requirements.

[0066] Furthermore, the connecting structure 50 includes grooves 51 provided on two opposite sides of the second housing 41, and sliders 52 respectively provided on the first sidewall 111 and the second sidewall 112 of the first housing 11. During installation, a portion of the second housing 41 is embedded in the slot 114 of the first housing 11, and the sliders 52 are correspondingly inserted into and slide within the grooves 51, thereby achieving a stable connection between the second housing 41 and the first housing 11.

[0067] The control module 42 consists of components such as a microprocessor and a circuit board. It is housed in the second housing 41 and electrically connected to the nebulizer 35. It is used to receive user input signals or other instructions and control the nebulization time of the nebulizer 35 to achieve the required dosage, such as 10 ml per dose.

[0068] The battery 43 is disposed inside the second housing 41 and is electrically connected to the control module 42, providing the power required for the operation of the control module 42.

[0069] Accordingly, the present invention can achieve the following effects:

[0070] 1. Drug nebulization function: The nebulizer, driven by the control unit, can convert the liquid medicine in the storage bottle into fine droplets.

[0071] 2. Drug delivery function: The design of rubber stopper and spring regulates the volume change of the drug solution in the storage bottle, ensuring that the drug solution is smoothly and accurately delivered to the nebulizer, avoiding stagnation or gaps, thereby achieving a highly efficient and stable drug delivery process.

[0072] 3. Medicine storage function: The design of the medicine storage bottle and one-way device ensures the airtightness of the medicine storage, preventing the entry of external air or contaminants, while preventing medicine leakage and maintaining the stability and safety of the medicine.

[0073] 4. Detachable Design: The inhalation unit features a detachable design, avoiding the bacterial buildup caused by reusing the mouthpiece, reducing the possibility of cross-infection, and ensuring safe use. Furthermore, the assembly unit and control unit are also detachable. After the medication is used up, the control unit can be retained while other components are replaced, eliminating the need to replace the entire unit. This significantly reduces operating costs and improves the equipment's sustainability.

[0074] 5. Easy to operate and carry: Suitable for home and hospital environments, and convenient for long-term treatment.
