,TagSPECI:TECHNICAL FIELD

[001] The present subject matter described herein, in general, relates to devices and methods for generating and delivering a nicotine aerosol to a user, and more particularly to devices and methods for generating and delivering an aerosol of a Nicotine to a user's lungs without burning or heating of tobacco and/or nicotine thereby achieving effective, efficient and productive process with overall decrease in time of Nicotine Replacement Therapy.

BACKGROUND

[002] Considering the various ways and means of smoking cessation, Nicotine replacement therapy (NRT) appears promising. These products may not contain undesirable compounds that may be found in smoke. The goal of such therapies are to cut down the nicotine cravings and ease the symptoms of nicotine withdrawal.

[003] The primary form of smoking cessation is Nicotine Replacement Therapy (NRT). Such methods seek to deliver nicotine to the body through a pulmonary or buccal route. This ensures that no harsh components of smoke enter the bloodstream while satisfying the nicotine craving. Traditional methods of generating an aerosol so as to deliver nicotine to the body includes processes such as combustion, heat or a propellant of nicotine.

[004] Various attempts have been made at achieving the above viz., 6272/DELNP/2009 and 7127DELNP2011. The cited prior arts have inherent drawback in the design of the device to deliver the nicotine to the user. The prior-art documents ‘6272 and ‘7127 are three segmented in nature (third segment is optional) wherein, the gaseous carrier communicates with the delivery enhancing compound (acid) in the first internal area and subsequently, the said gaseous carrier with the delivery enhancing compound contacts the nicotine / alkaloids in the second internal area to generate aerosol.

[005] Apart from the above, there are various other prior-art documents that provides various different designs and forms of NRT devices/cigarettes/ devices to generate and deliver a nicotine aerosol to a subject.

[006] The prior-art document US8752557 discloses a device of three chambers, wherein it permits the air to pass through the first chamber with liquid nicotine to form nicotine vapour and then enters the second chamber containing volatile acid to form acid vapour and in the third chamber, the said acid vapour and nicotine vapour admix to form aerosol of a nicotine salt.

[007] The prior-art document US20140261399A1 relates to the delivery of liquid nicotine, large size droplets suitable for a buccal delivery.

[008] The prior-art document US4945929 relates to a nicotine dispensing aerosol device that has nicotine and propellant storage containers connected to atomization nozzle from which a nicotine-aerosol spray can flow.

[009] However, the above mentioned prior-art documents and the traditionally available approaches suffer with following issues:
· The key shortcomings of NRT devices is that they do not provide an experience through the conventional smoking articles such as:
o Rapid Nicotine Delivery through better pharmacokinetics for Instant Craving Relief;
o Hand-to-Mouth action to satisfy the behavioral ritual;
o Sensory Inhalation cues in the respiratory tract;
· The traditional approaches and NRT devices generates aerosol by a method of combustion, heat or a propellant.
· The traditional approaches and NRT device generates some toxic smoke components.
· The NRT devices are multi chambered devices/segmented devices with various compartments for various chemical material for generation of aerosol for delivery.

[0010] Hence, there is a dire need to address all the drawbacks known in the art through a device and method which delivers nicotine to the users without burning or heating of tobacco and/or nicotine thereby achieving effective, efficient and productive process with overall decrease in time of Nicotine Replacement Therapy. Further, there is also a need to provide a device which is similar to that of a conventional cigarette which when bought by consumer habituated to smoking cigarettes shall not feel much difference in usage. Also, most importantly, there is a need to provide a device which eliminates toxic smoke components and provides similar pleasure as that of convention cigarette.
