Disclosed is a drug vaporization and inhalation device. The present invention is configured such that when an infected patient with asthma, a coronavirus, or the like inhales a particulate drug, the drug is contained in vaporized steam, and therefore, the drug can sufficiently arrive at the lungs of the infected patient with asthma, a coronavirus, or the like, without loss, thereby preventing a given amount of the drug from remaining in an inhalation container and improving the drug inhalation efficiency of the infected patient with asthma, a coronavirus, or the like along with prevention of excessive inhalation of the drug.

A nasal delivery device for delivering substance to a nasal cavity of a subject, the delivery device comprising: a substance supply unit for supplying a dose of substance to be delivered to the nasal cavity of the subject, the substance supply unit including an inlet and an outlet; a nosepiece unit including a nosepiece for fitting to a nasal cavity of the subject and being in fluid communication with the outlet of the substance supply unit; and a mouthpiece unit including a mouthpiece in fluid communication with the inlet of the substance supply unit and through which the subject in use exhales such as to entrain substance from the container chamber and deliver the same through the nosepiece, and at least one temperature modifier for reducing a temperature of the exhaled air flow such as to reduce the absolute humidity thereof.

The invention provides an apparatus for use in aerosolized delivery of a powder, and comprises a first chamber containing gas at a first pressure higher than atmospheric pressure, and a second chamber containing gas at a second pressure higher than atmospheric pressure. The apparatus also comprises a powder, contained within the first or second chamber. The first chamber has a first external wall and a separating wall, the separating wall being shared with the second chamber. The first external wall or the separating wall is configured to rupture if the pressure difference across it becomes equal to or greater than a threshold pressure difference. In particular, the apparatus is configured so that the difference between the second pressure and atmospheric pressure is greater than the threshold pressure difference. In an initial state, the apparatus is configured such that the difference between the second pressure and the first pressure is less than the pressure difference required to rupture the separating wall, and the difference between the first pressure and atmospheric pressure is less than the pressure difference required to rupture the first external wall.

A fluid dispenser device having a dispenser head; an air expeller; and a reservoir containing a single dose of fluid. The reservoir includes a proximal axial end and a distal axial end, and is removably mounted so that after the device has been actuated, the empty reservoir can be removed from the device and replaced by a new full reservoir. The air expeller is adapted to return to its rest position to enable a new actuation with the new full reservoir. The dispenser head includes a proximal perforator tip to perforate the proximal axial end of the reservoir. The device includes a movable perforator member that slides axially around the dispenser head between a loading position and an actuation position and includes a distal perforator tip adapted to perforate the distal axial end of the reservoir when the movable perforator member is moved into its actuation position.

Devices, cartridges, and method are described herein for emulating smoking wherein a device generates an aerosol for inhalation by a subject by heating a viscous material that can have a tactile response in the mouth or respiratory tract, while reducing Hoffman analytes and mutagenic compounds delivered to the user as compared to a common tobacco cigarette.

The present invention relates to an inhaler device for delivering a dose of medicament in dry powder form from a container to a patient in need thereof. The inhaler comprises a swirl chamber in which particles of the medicament entrained in an airflow swirl upon inhalation thereby breaking up the agglomerates into finest dispersed powder.

Disclosed is a hand piece for an aesthetic and medical device including a first body portion having a cylindrical structure in which a cartridge mounting space a second body portion bound to a lower side of the first body portion and having a cylindrical structure having an upper side on which an air pressure providing portion configured to provide air pressure to the cartridge-mounting space and the auxiliary air flow paths is mounted and a spray head portion bound to an upper body of the first body portion and having a central part on which a spray needle bound to an upper body of the cartridge to upwardly spray the liquid cosmetic product or liquid medication accommodated in the cartridge is mounted.

The present invention relates to an inhalation device (1), to the use thereof, and to a kit comprising the inhalation device. The inhalation device (1) has an air inlet (14), an air outlet (15) designed as a mouthpiece or nosepiece, and a recess (17) which is designed to receive a container (2) with an inhalable substance. An air duct (L) extends from the air inlet (14) through the recess (17) to the air outlet (15). Moreover, the inhalation device (1) has at least one hollow mandrel (16, 16′) which protrudes into the recess (17) and from which at least one air delivery line (14′, 14″) extends to the air inlet (14) or at least one air outlet line (15′) extends to the air outlet (15). The inhalation device (1) is characterized in that the inhalation device (1) has two limbs (11, 12), each with a work end (11′, 12′) and with an actuation end (11″, 12″), wherein the limbs (11, 12) are connected by means of a joint (13) which lies between the work ends (11′, 12′) and the actuation ends (11″, 12″). Furthermore, the recess (17) is defined between the mutually facing sides of both limbs (11, 12) at the work ends (11′, 12′), wherein the at least one hollow mandrel (16, 16′) is arranged inside the recess (17) on one of the mutually facing sides of both limbs (11, 12). The air inlet (14) and the air outlet (15) are arranged at the work end (11′, 12′) on a side, directed away from the recess (17), of at least one of the limbs (11, 12).

A method of delivering a substance, such as one or more of a triptan, a nasal steroid or carbon dioxide gas, to the nasal cavity of a subject, in particular for the treatment of headaches, for example, migraine, or rhinosinusitis, for example, chronic rhinosinusitis, optionally with polyps, the method comprising the steps of fitting a nosepiece to one nostril of the subject, delivering the substance through the nosepiece to the posterior region of the nasal cavity of the subject.

Adherence monitors are disclosed, incorporating cap removal sensors together with a determined time period in order to determine that a dose of medicament has been dispensed. In another form, cap removal data is combined with acoustic data to determine that a dose of medicament has been dispensed. Several specific structural arrangements are also disclosed.
