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.

A metered dose inhaler having a body for receiving a medicinal canister. A dome shaped motorized unit is attached to the main body of the inhaler. A lower mouthpiece end is in communication with an output valve of the canister for issuing an atomized medicinal spray. A plurality of apertures are defined along any of the sides or front and back walls of the body such that, upon depressing a trigger associated with the canister in combination with patient inhalation, the actuation of the motor combines results in more efficient delivery of the spray and to better direct the spray into the patient's respiratory system. A further variant incorporates a motorized cap, such as for use by handicapped individuals who may be unable to actuate the metered dose inhaler due to anatomical or physiological disabilities.

An elastomeric component includes a body feature and a retaining feature coupled to the body feature. The retaining feature includes an insertion end portion, and a retention end portion spaced apart from the insertion end portion along a longitudinal axis. The insertion end portion defines a catch spaced apart from the retention end portion and having a contact location adapted to make first contact with an edge of a retaining hole. The contact location is spaced apart from the catch a first distance. The retaining feature has a blind pocket extending from the retention end portion interiorly of the retaining feature along the longitudinal axis. The blind pocket terminates at an end location spaced from the catch. The elastomeric component may be coupled to a wall defining the retaining hole. Methods of assembly, and an apparatus for installation, are also provided.

A micronization unit for a solid active agent, such as a salt, preferably table salt (NaCl), for inhalation, is described.

The micronization unit includes a closed rotary drum containing a solid active agent having a grain size, preferably 0.1-4 millimeters (mm). Wall surfaces of the micronization unit are made at least in part of a material having a filtering capacity of 0.1-1000 micrometers (m). The material preferably is a mesh-like or microperforated material. The rotary drum dispenses particles of reduced size as it rotates.

An inhaler for delivery of a medicament by inhalation is disclosed. The inhaler comprises the following components. An inhaler body for receiving a canister having a dispensing valve. A drive mechanism comprising a biasing means such as a spring and a moving component such as a yoke, the drive mechanism for driving the canister, when received in the inhaler body, from a rest position in which the valve is closed to at least an actuating position in which the valve is open. The drive mechanism drives the canister when the biasing means is released from a loaded configuration to move the moving component from a first position to a second position. A resetting mechanism, for example a mouthpiece cap arrangement for pushing upwardly on the yoke, for resetting the drive mechanism by moving the moving component from the second position to the first position and reloading the biasing means to the loaded configuration. A return mechanism for returning the canister from the actuating position to the rest position, wherein the return mechanism comprises a damping system, the damping system configured to enable the canister to automatically return from the actuating position to the rest position within a predetermined time period measured from the release of the biasing means from the loaded configuration. A method of operation of an inhaler is also disclosed.

The present invention provides a new inhaler device for the storage and/or administration of inhalable liquids to a patient offering one or more advantages or improvements over known inhalers, particularly inhalers for the delivery of halogenated volatile liquids such as methoxyflurane for use as an analgesic.

An inhalation system including a fluid transfer member, a valve member, a cartridge assembly, and a mouthpiece, and a method of use thereof are provided. The valve member connects to an open end of the fluid transfer member. The cartridge assembly, positioned within the valve member, includes a substance holder and an absorbent member accommodated within a cartridge for containing and absorbing an inhaling substance. When the valve member connects to a vaporizer, the vaporizer heats the absorbent member to vaporize and release an inhaling fluid into the fluid transfer member. When the valve member connects to the mouthpiece, the valve member receives and transfers the inhaling fluid vapor from the fluid transfer member to a user's mouth via the mouthpiece. The locking mouthpiece assembly allows authentication of the user prior to releasing the inhaling fluid to the user's mouth.

Nasal medication or drug delivery devices and methods for delivering adjustable or variable metered volumetric doses of medication or drugs to a nasal passageway of a user or patient. Relative movement between portions of a reservoir establish a set volume of medication for delivery. The delivery device may include a nosepiece for fitting into the nostril of the user or patient, a medication or drug reservoir or dosing chamber, and an external reservoir adapter for providing the medication from an external reservoir.

An inhaler, preferably for insertion into a nostril, in particular a horse's nostril, with an inhalation valve, which has a movable valve element, whereby the valve element is designed in an annular manner and has an outer edge and an inner edge, whereby the valve element is fastened at the outer edge, the inner edge forms the boundary of an indentation of the valve element, and the inhalation valve has a valve body seat that corresponds to the inner edge.

The present disclosure provides an aerosol delivery device and a cartridge for an aerosol delivery device. In various implementations, the cartridge may comprise a housing defining a liquid reservoir, an atomizer configured to produce an aerosol, the atomizer comprising a first liquid transport element, a second liquid transport element, and a microvalve located between the liquid reservoir and the second liquid transport element. The microvalve may comprise a base member including at least one channel, and an actuating member at least a portion of which comprises a shape-memory material, and which is configured to move between a first position and a second position, wherein in the first position, the actuating member substantially blocks fluid flow from the liquid reservoir through the channel, and in the second position, the actuating member allows fluid flow from the liquid reservoir through the channel and to the second liquid transport element.
