A dose ring for a dry powder inhaler (DPI) device includes an aluminum foil member covering particulate medication cavities and through holes. The device includes hinged flaps formed by a cut so that one radial side is uncut and forms a hinge. Each flap can cover both a cavity for particulate medication and a through hole located between that cavity and the circular inside edge of the dose ring.

Dry powder inhaler systems for pulmonary delivery of pharmaceuticals are disclosed.

A container for holding, dispensing and/or storing a preferably liquid medicament preparation is proposed, which comprises an inner space for the medicament preparation and an at least partially multi-layered wall structure defining the inner space, the wall structure comprising a first layer with a first through-opening of less than 40 m. Alternatively or additionally, the wall structure comprises a second and third layer, a second through-opening being provided in the second layer and the third layer covering or closing off the wall structure.

A vaporizing assembly for an aerosol-generating system may comprise a delivery device and a heater assembly. The heater assembly may comprise a heat resistive substrate and a heating element. The delivery device is configured to deliver an aerosol-forming substrate to at least a surface of the heat resistive substrate, wherein the heating element is isolated or separated from the aerosol-forming substrate by the heat resistive substrate. The present disclosure is also directed to a method for generating an aerosol.

A breath actuated nebulizer for administration of an inhaled medication to a patient is provided with a generally cylindrical body in a horizontal orientation to the patient. Within the body is a Venturi configured to nebulizer a liquid medication in a reservoir. Within the body is a shaft integrated with a baffle and diaphragm that slides horizontally in response to the breathing of a patient. During inhalation by the patient, the diaphragm flexes shifting the baffle over the Venturi, allowing nebulization to occur. When the patient exhales, the diaphragm flexes to a default position in which the baffle is distal to the Venturi, thereby stopping the nebulization. The diaphragm is biased to rest in this default position until the patient inhales again.

The present disclosure relates to electronic smoking articles exhibiting improved moisture control of a reservoir contained therein. The reservoir can be formed of fibrous materials, such as cellulose acetate fiber, thermoplastic fiber, non-thermoplastic fiber, or a combination thereof. The disclosure further provides methods for forming electronic smoking articles and methods of packaging electronic smoking articles (including cartridges thereof) so as to improve moisture control of the reservoir.

An atomization core assembly (10A, 10B), an atomizer (100), and an electronic atomization device (300). The atomization core assembly (10A, 10B) comprises: a liquid guide element (10) comprising an atomization surface (11) and a liquid absorption surface (12) opposite to the atomization surface (11); a heating element (20) disposed on the atomization surface (11) and used for heating at least part of a liquid matrix absorbed by the liquid guide element (10) to generate aerosol; and a first sealing member (30) having a first open end (31), a first closed end (32) opposite to the first open end (31), and a sealing member sidewall (33) extending from the first closed end (32) to the first open end (31). The first sealing member (30) accommodates the liquid guide element (10) and exposes the atomization surface (11). The first sealing member (30) is further provided with a liquid inlet (34) in the sealing member sidewall (33), so that the liquid absorption surface (12) is communicated with the outside through the liquid inlet (34). The surfaces of the liquid guide element (10) other than the atomization surface (11) are covered by the first sealing member (30), so that liquid absorbed by the liquid guide element can be prevented from leaking from these surfaces.

An atomization core assembly (10A), an atomizer (100) and an electronic atomization device (300). The atomization core assembly (10A) comprises: a liquid guide element (10) comprising an atomization face (11) and a liquid absorption face (12); a heating element (20) arranged on the atomization face (11) and used for heating at least some of a liquid matrix absorbed by the liquid guide element (10), so as to generate aerosol; and a first holder (40) for accommodating the liquid guide element (10), wherein a holder side wall (44) of the first holder (40) is provided with a gas intake groove (47) and a liquid temporary-storage groove (48), the gas intake groove (47) is in communication with a space above the atomization face (11) via a gas inlet (471), the liquid temporary-storage groove (48) is in communication with the space above the atomization face (11) via an overflow port (481), and the gas intake groove (47) and the liquid temporary-storage groove (48) are separated by means of an isolation portion (442). In the atomization core assembly (10A), the liquid or condensate of an e-liquid can flow into the liquid temporary-storage groove (48) along the overflow port (481) and is then stored in the liquid temporary-storage groove (48), such that the liquid is not prone to leaking along the gas intake groove (47).

A medical device includes a user interface component and an energy harvesting system coupled to the user interface component. The energy harvesting system energy includes a harvesting component, a power storage device connected to the energy harvesting component and an output is coupled to the user interface and operably connected to the power storage device. A method of using the medical device is also provided.
