A dry powder inhalation device is disclosed. In one optional aspect, the device includes a housing, a base plate, a receptacle for a medicament and a mouthpiece. The base plate is engageable with the housing to form a main space with a main air inlet. The mouthpiece includes an inner conduit connected to its outlet and is engageable with the base plate to fluidly connect the inner conduit to the receptacle. The receptacle is fluidly connected to the main space, so that upon inhalation by a user, air can be drawn through the main air inlet into the main space and onward through the receptacle into the inner conduit. The mouthpiece and the base plate form an auxiliary space with an auxiliary air inlet, wherein the auxiliary space is fluidly connected to the main space.

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.

The introduction of electronics into a drug delivery device may introduce certain technical challenges, such as durability, electro-mechanical integration, and drug delivery performance. The present disclosure provides solutions for inclusion of an electronics module with an inhaler. For example, heat stakes may be used to secure a printed circuit board (PCB) to an electronics module's housing. Also for example, a slider may be used to transfer vertical movement of an inhaler's yoke to an electronics module's switch. Also for example, certain seals may be used when interfacing the electronics module to other portions of the device's housing to achieve a desired performance.

A spacer device for use with a metered dose inhaler (MDI). The spacer device comprises an aerosol chamber for holding the aerosolized medication sprayed from the MDI. According to one particular design, the aerosol chamber has a forward shell, a rear shell, and an extendable barrel in between. The extendable barrel comprises a flexible plastic sheath that is supported by a coiled wire spring. The spacer device further comprises a mounting bracket to hold the MDI. The mounting bracket holds the MDI such that the spray outlet of the MDI is mated with the aerosol chamber. Also, the assembly is configured such that the aerosol chamber is aligned substantially parallel to the actuator boot of the MDI. During use, the aerosol chamber is folded downward away from the MDI. The aerosol chamber is then extended outward to increase its volume.

The present disclosure relates to aerosol delivery devices. The aerosol delivery devices may include a housing and a cartridge including an atomizer and a reservoir configured to contain an aerosol precursor composition. The cartridge may be configured to move relative to at least a portion of the housing between a retracted configuration and an extended configuration. Related assembly methods are also provided.

It is provided a dry powder inhaler (2) for a capsule containing dry powder, the dry powder inhaler (2) comprises: a mouth piece (14) with a mouth portion, wherein an opening of the mouth portion leads into a duct; a one-piece base body (10) comprising a capsule chamber portion and being attached to a covering body (6); and an actuator button (8) movable relative to the one-piece base body (10) from a normal position to a perforation position along an actuation direction, wherein the actuation direction is perpendicular to the longitudinal axis, and wherein perforation needles attached to the actuator button (8) extend into the capsule chamber when the actuator button (8) is in the perforation position.

An electronic smoking device (210, 310, 410) has two portions (12, 13) wherein one of the portions (12, 13) comprises a cavity (240, 340, 440) for a liquid reservoir (234, 334, 434). The portions (12, 13) can be moved with respect to each other, by a movement and a respective counter movement, at least between an insertion configuration and a closed cavity configuration. In the insertion configuration a liquid reservoir (234, 334, 434) can be inserted into the cavity (340, 440). In a closed cavity configuration, the cavity (240, 340, 440) is closed by the other portion and a liquid reservoir opening element (70) of said one or the other portion opens the housed liquid reservoir (234, 334, 434).

An upper-assembly electronic cigarette atomizer is provided. The atomizer may include a liquid storage cup having an upper opening, and a head cover component connected with the upper opening in a threaded manner. The liquid storage cup and the head cover component may form a closed space for containing an e-liquid. The head cover component may be configured to be detached from the liquid storage cup as an integral unit. An electronic cigarette containing an upper-assembly electronic cigarette atomizer and a method of assembly are also provided.

The disclosure relates to an electronic atomizing device and an atomizer and a liquid injection structure thereof. The liquid injection structure includes an outer pipe provided with an exhaust port and a liquid injection assembly including a sleeve pipe disposed in the outer pipe and a liquid injection pipe disposed in the sleeve pipe. The liquid injection pipe is provided with a liquid injection port, and is axially movable relative to the sleeve pipe between a first position where the sleeve pipe seals the liquid injection port and a second position where the seal of the liquid injection port by the sleeve pipe is released. The sleeve pipe is axially movable relative to the outer pipe between a third position where the sleeve pipe seals the exhaust port and a fourth position where the seal of the exhaust port by the sleeve pipe is released.

An apparatus for delivering a therapeutic agent may be associated with a cap for a bottle that contains a prescription for a drug to which the therapeutic agent corresponds. When the prescription bottle holds an opioid, the therapeutic agent may be a substance that counteracts the effects of the opioid. The apparatus may include a nozzle that facilitates nasal administration of the therapeutic agent. The apparatus may be capable of attaching to a cap for a prescription bottle, or the apparatus may have a configuration that enables it to serve as the cap for the prescription bottle.
