Description

Technical Field

[0001] This invention relates to a drug delivery device, specifically to a nasal inhaler for smoking cessation that delivers drugs via the nasal olfactory system and its drug carrier. Background Technology

[0002] Long-term smoking causes harmful substances such as tar and nicotine to enter the lungs and blood vessels, increasing the risk of lung cancer, heart disease, and stroke. Secondhand smoke also poses a serious threat to the health of others. Current smoking cessation methods include medication (such as varenicline tartrate tablets), nicotine replacement therapy (such as patches and chewing gum), and e-cigarettes.

[0003] However, existing technologies have the following drawbacks: First, prescription drug therapy requires doctor's guidance and may cause mucosal irritation or side effects; second, nicotine replacement therapy carries the risk of addiction and local respiratory discomfort; third, e-cigarette devices rely on battery power and high-temperature heating principles, which not only produce secondary pollution such as formaldehyde and heavy metals, but also pose safety hazards in extreme environments (such as high altitude and low pressure, deep sea and high pressure, or special places where open flames are prohibited).

[0004] Furthermore, among existing patented technologies, the "mask-style smoking cover" with application number 2013107344941 mainly focuses on physical coverage; being a mask, its smoking cessation effect is not ideal. The "secondhand smoke purification device" with application number 2022114772191 is mainly used to filter residual smoke and cannot be used as an active drug delivery method. In summary, existing technologies lack a highly efficient, safe, and pollution-free drug delivery solution that can directly act on the olfactory nerves of the nasal cavity and is unaffected by ambient air pressure. Summary of the Invention

[0005] To address the shortcomings of the prior art, this invention provides a nasal inhaler for smoking cessation and its drug carrier, which aims to deliver drugs directly to the nasal cavity, sinuses, and upper respiratory tract via the olfactory system through the pressure difference generated by nasal inhalation, thereby achieving efficient, low-dose, safe, and side-effect-free drug delivery.

[0006] This invention includes: a nasal inhaler and a drug carrier compartment communicating with the nasal inhaler; wherein, the drug carrier compartment has a release end near one end of the nasal inhaler, and the release end is connected to a clamping end. By generating a negative inhalation pressure in the nasal inhaler, air is driven to flow through the drug carrier in the drug carrier compartment, so that the drug is delivered to the nasal inhaler region via the release end.

[0007] In addition, the present invention has the following technical features: the nasal suction part can be configured as a nasal mask or nasal plug structure according to wearing requirements; the clamping end has a stepped inner diameter structure for fastening the drug carrier; the drug carrier compartment is provided with a bypass structure for adjusting the air intake.

[0008] The technical effects of this invention are as follows: 1. Highly efficient delivery: It acts directly on the olfactory sensory nerves in the nasal cavity, achieving the goal of smoking cessation through stimulation of a small amount of drug, thus improving the efficiency of the drug's effect on the nervous system; 2. High safety: No electronic components or high-temperature heating structures are required, eliminating the risks of battery explosion, high-temperature burns, and the generation of volatile harmful substances; 3. Strong environmental adaptability: It does not rely on electricity or air pressure to drive, is not affected by external air pressure fluctuations, and is suitable for high-altitude, underwater and special environments where open flames are prohibited; 4. Hygienic and environmentally friendly: It does not produce smoke or secondary pollution, the exhaled air is clean, and the structure is simple, making it easy to replace drug carriers of different specifications.

[0010] In the diagram, the markings are: 1-nasal inhalation section; 2-drug carrier compartment; 3-clamping end; 4-outer diameter of drug carrier compartment; 5-first inner diameter of drug carrier compartment; 6-second inner diameter of drug carrier compartment; 7-release end; 8-bypass of gas volume. Detailed Implementation

[0011] The specific technical solutions of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0012] The present invention provides a nasal inhaler for smoking cessation, the core working principle of which is to drive the drug from the carrier chamber to the respiratory tract and olfactory area through the pressure difference generated by nasal inhalation.

[0013] This nasal inhaler smoking cessation device has a drug carrier compartment 2 connected to the lower part of the nasal inhaler 1 for placing the drug carrier. The end of the drug carrier compartment 2 near the nasal inhaler 1 is a release end 7, which is connected to the clamping end 3.

[0014] Depending on the application scenario, the nasal suction section 1 has the following two structures: Example 1 (Nose Mask Structure): A drug carrier compartment 2 for placing a drug carrier is connected below the nasal suction section 1. The end of the drug carrier compartment 2 closest to the nasal suction section 1 is a release end 7, which is connected to the clamping end 3. The outer wall of the nose mask has a soft groove for gripping and cushioning the nose, and its inner release end has a buffer zone and an inhalation filter zone, with a filter material in the filter zone. The user inserts the drug carrier into the drug carrier compartment and inhales, allowing air to flow through the drug carrier and into the nasal cavity. Example 2 (Nasal Plug Structure): A drug carrier compartment 2 for placing a drug carrier is connected below the nasal suction unit 1. The drug carrier compartment 2 is connected to the nasal suction unit 1. It includes a nasal plug seat and a nasal plug pad installed on the nasal plug seat; the nasal plug seat is provided with a drug delivery channel communicating with the drug carrier compartment 2.

[0015] The clamping end 3 includes a first clamping end and a second clamping end, with the end closer to the inlet end of the drug carrier compartment being the first clamping end. A transition slope is provided between the first clamping end and the second clamping end, and the inner diameter of the first clamping end is larger than the inner diameter of the second clamping end. This stepped slope structure ensures sufficient tightness when drug carriers of different sizes are inserted into the drug carrier compartment.

[0016] The side wall of the drug carrier compartment 2 is provided with a bypass structure 8 for adjusting the air intake. In one option, the bypass is implemented by a rotatable or sliding adjustment kit; in another option, the air intake is changed by partially blocking the bypass hole by controlling the insertion depth of the drug carrier in the drug carrier compartment.

[0017] The drug carrier used in this invention is a cylindrical encapsulated structure, which encapsulates an active volatile drug. This drug carrier is permeable, allowing gas to pass through and circulate within the drug carrier chamber (2). In terms of specific dimensions, the outer diameter of the drug carrier chamber (2) is approximately 10 mm; its interior has two stepped inner diameters: a first inner diameter of 7.7-7.8 mm and a second inner diameter of 5.4-5.5 mm. By replacing drug carriers of different specifications, dosages, or active ingredients, this device can meet multifunctional therapeutic needs.

[0018] In summary, this invention achieves stable application in extreme environments (such as space stations, deep sea, and different air pressures) through structural optimization, and has the technical advantages of low pollution, easy portability, and high efficiency.

[0019] The above description is only a preferred embodiment of the present invention. Any modifications or equivalent transformations made based on the technical solution of the present invention should be included within the protection scope of the present invention.
