The present invention provides dry powder inhaler (DPI) devices (100) for dispensing dry powder and methods for using the same. The DPI devices feature vortex mechanisms for directing air in a turbulent manner sufficient to entrain an amount of a dry powder dose for delivery into a user's lungs. The DPI devices feature replaceable dry powder cartridges (200). The DPI devices also feature a retractable configuration for storage and for accidental dispensing of dry powder. The DPI devices dispense dry powder in controlled dosages.

A capsule may include a housing, an aerosol-forming substrate, and a heater. The housing defines inlet openings, outlet openings, and a chamber between the inlet openings and the outlet openings. The chamber may have a longest dimension extending from at least one of the inlet openings to a corresponding one of the outlet openings. The aerosol-forming substrate is within the chamber of the housing. The heater is embedded in the housing. The heater includes a first end section, an intermediate section, and a second end section. The intermediate section is disposed within the aerosol-forming substrate in the chamber. An aerosol-generating device may include a device body with a lid configured to open to permit an insertion of the capsule and configured to close to engage the capsule within the device body.

The present disclosure is a handheld apparatus that vaporizes plant-based or synthetic compounds, for the purpose of inhalation, or diffusion into an external environment. More specifically, the disclosure describes a handheld apparatus wherein a laser beam from an internal laser unit heats compounds, such as dried plant, tinctures, resins, or essential oils, to the compound's vaporization temperature for inhalation, or diffusion as part of aromatherapy or other holistic therapeutic treatments.

An apparatus to provide scent or other substances (e.g., active agent) includes a thin profile delivery apparatus that includes an actuator (e.g., nebulizer) and drive circuit to generate a spray, aerosol or vapor. The apparatus may have a slot to removably a media cartridge that carries the scent or other substances. The apparatus may include two contacts (e.g., buttons), opposed to one another across a dimension of the apparatus. Activation may require both engagement of both contacts, for instance concurrently, or even successive engagement of both contacts, in quick succession. Activation may further require a correct orientation of the apparatus. The apparatus may have a form factor similar to a conventional credit or debit card, and may be pliable or pliably resilient. The delivery apparatus can be used in entertainment (e.g., food or cooking programming), and in healthcare (e.g., control of metabolism).

A breath-powered, dry powder inhaler, a cartridge, and a pulmonary drug delivery system are provided. The dry powder inhaler can be provided with or without a unit dose cartridge for using with the inhaler. The inhaler and/or cartridge can be provided with a drug delivery formulation comprising, for example, a diketopiperazine and an active ingredient, including, peptides and proteins such as insulin, oxyntomodulin and glucagon-like peptide.

A collapsible spacer for use with a metered-dose-inhaler (MDI) medicament cartridge the spacer being movable between an expanded configuration for operation of the spacer and a collapsed configuration for transport or storage of the spacer. The spacer includes: an internal chamber for receiving a medicament dose when the spacer is in the expanded configuration and a cartridge dock for, in use, engaging with an MDI cartridge and permitting delivery of a medicament dose from the MDI cartridge to the internal chamber. The spacer further includes a mouthpiece permitting inhalation of a medicament dose from the internal chamber and a storage volume configured to accommodate the cartridge dock and an MDI cartridge. The cartridge dock is retractable into the storage volume in a retraction direction to store the MDI cartridge within the storage volume whilst maintaining engagement between the MDI cartridge and the cartridge dock. The cartridge dock is configured to receive and engage with the MDI cartridge in a cartridge orientation that is not aligned with the retraction direction.

A mesh nebulizer that nebulizes and ejects a medicinal liquid through a mesh portion, includes a main body including a vibration portion including a vibration surface, and a medicinal liquid pack to be detachably mounted on the main body. The medicinal liquid pack includes a lid in which the mesh portion is provided, and a medicinal liquid container that includes a recessed portion that is open toward the mesh portion and is covered by the lid, the medicinal liquid being contained in the recessed portion. At least a portion of a bottom surface of the recessed portion of the medicinal liquid container that is to oppose the vibration surface is made of a stretchable material. When the medicinal liquid pack is mounted on the main body, the stretchable material of the bottom surface stretches, allowing the vibration surface to approach the mesh portion of the lid.

An elongated aerosol-generating device to receive an aerosol-generating article is provided, including: a heater to heat the article, to penetrate an internal portion of article, and extending longitudinally with respect to the device; and an extractor to extract the article received in the device, the extractor being slidable within the device and between an operating position with the heater in contact with the article, and an extraction position with the heater separated from article, the extractor being removable from the device and including a cavity to receive the article, a first aperture defined through an end-wall of the cavity to allow the heater to penetrate the cavity when the extractor is moved between the positions, in which the extractor further defines an air-flow channel to allow air flow into the cavity, an inlet of the air-flow channel being positioned radially-outward of the first aperture.

My powder inhalers are described. The dry powder inhaler includes an air inlet, a reservoir and an airway assembly. A mouthpiece airway is connected to a first airway of the airway assembly. An airway head is attached to the airway assembly and it extends into the reservoir cavity. In certain embodiments, the airway head has a sharpened or beveled edge. At least one airway assembly opening is present in the airway assembly for connecting the reservoir cavity to the first airway. Methods for dispensing dry powder into an airway of a dry powder inhaler and inhaling dry powder from a dry powder inhaler is also disclosed. Embodiments of a dry powder inhaler having a two-stage air movement are also described.

A device for inhaling powdery substances contained in capsules has a housing, a capsule receiver, a closing cover, a mouth piece, and a closure cap. The closure cap is designed to cover simultaneously the mouthpiece, closing cover and capsule receiver, wherein the closure cap, mouthpiece and closing cover are hinged in a pivoting manner. Two pivot axes, which are different but run in the same direction, are formed, which, in respect of a side view in which geometric axes of the pivot axes are represented in the form of points, are arranged next to each other and on a same side of the capsule receiver. In a usage state of the device, the first pivot axis is arranged closer to the capsule receiver. The closing cover and the mouthpiece can be pivoted about the first pivot axis and only the closure cap can be pivoted about the second pivot axis.
