A delivery device for and method of delivering substance, the delivery device comprising: an outlet member through which substance is in use delivered in an entraining gas flow; and a substance supply unit for supplying substance to be entrained by an entraining gas flow as one or both of a vapor or a fine aerosol mist, wherein the substance supply unit comprises a flow channel which is fluidly connected to the outlet member, and a substance supporting element for supporting substance, at least a surface of which is in use disposed in the flow channel.

An oscillating positive expiratory pressure device comprising a housing enclosing at least one chamber, a chamber inlet configured to receive exhaled air into the at least one chamber, and a chamber outlet configured to permit exhaled air to exit the at least one chamber. A channel is positioned in an exhalation flow path between the chamber inlet and the chamber outlet, with the channel being moveably connected to a chamber of the at least one chamber. An air flow regulator is moveable with respect to the channel between a first position, where the flow of air through the channel is restricted and a second position, where the flow of air through the channel is less restricted, the air flow regulator being configured to repeatedly move between the first position and the second position in response to a flow of exhaled air.

A delivery device for and method of delivering a powdered substance, in particular a triptan, such as sumatriptan, to the posterior region of a nasal cavity of a subject, in particular for the treatment of headaches, for example, cluster headaches and migraine, and neuropathic pain, the delivery device comprising: a nosepiece for insertion into a nasal cavity of a subject through which the powdered substance is delivered to the posterior region of the nasal cavity of the subject, in particular the upper posterior two thirds of the nasal cavity; and a substance supply unit which is operable to deliver the powdered substance through the nosepiece.

A nasal delivery device can include a nasal prong and an activation member. The nasal prong can have an opening at a top and bottom portion of the prong to allow for the passage of an aerosolized treatment agent through the nasal prong. The activation member can be positioned on the nasal delivery device at a location that is spaced apart from the subject's oral cavity when the nasal prong is received into the nostril of the subject. The activation member can detect a desired exhalation state of the subject and upon detection of the desired exhalation state, the activation member activates the delivery of the aerosolized treatment agent.

The present invention provides a device for delivering a predetermined volume of a substance, within at least one body cavity of a subject, comprising a predefined volume for containing the predetermined volume of the at least one substance; a delivery end for placement in proximity to the body cavity; the delivery end comprises at least one orifice of diameter D [mm]; a valve mechanically connectable to the container, characterized by at least two configurations: (i) an active configuration in which the valve enables delivery of predetermined amount M.sub.sub of the substance; and, (ii) an inactive configuration, in which the valve prevents delivery of the predetermined amount M.sub.sub of the substance from the container to the body cavity; and a fluid tight chamber configured to contain predetermined volume V.sub.gas of pressurized gas at a predetermined pressure, P.sub.gas.

A delivery device for and method of delivering a metered amount of substance, the delivery device comprising: a mouthpiece through which a user in use exhales; an outlet through which substance is in use delivered; a housing fluidly connected to the mouthpiece and the outlet, such that exhalation by the user through the mouthpiece creates an air flow through the housing and from the outlet; and a substance-dispensing unit which is disposed within the housing and operative to dispense a metered amount of substance into an entraining air flow as created through the housing.

A delivery device for delivering a metered amount of substance (L) in response to exhalation by a user, the delivery device comprising: a mouthpiece (5) through which the user in use exhales; an outlet (45) from which substance Is delivered; and a dispensing unit (35) which is operable to dispense a metered amount of substance through the outlet in response to exhalation by the user through the mouthpiece, wherein the dispensing unit comprises a body member (37) which includes a cavity (39) for containing a metered amount of substance, an outlet nozzle (43) which is fluidly connected to the cavity from which substance is in use delivered, and a dispensing (41) member which is movably disposed in the cavity and configured to be driven through the cavity by a driving pressure created by exhalation of the user, such as to cause substance to be delivered from the outlet nozzle.

A nasal delivery device can include a nasal prong and an activation member. The nasal prong can have an opening at a top and bottom portion of the prong to allow for the passage of an aerosolized treatment agent through the nasal prong. The activation member can be positioned on the nasal delivery device at a location that is spaced apart from the subject's oral cavity when the nasal prong is received into the nostril of the subject. The activation member can detect a desired exhalation state of the subject and upon detection of the desired exhalation state, the activation member activates the delivery of the aerosolized treatment agent.

The present disclosure relates to systems and methods for producing a consistent and effective herbal vapor. A sealed container pod may include a chamber wall defining an internal volume within which a pre-processed herbal composition (e.g., cannabis) is located. The container pod may include filters for the vapor produced from the herbal composition. The container pod may also include a support member for holding and evenly distributing the herbal composition within the internal volume during vaporization. A vaporizer may be configured to obtain information regarding the contents of the herbal composition. The vaporizer may expose the herbal composition to an automated series of timed temperature adjustments specifically tailored for producing a desirable herbal vapor. The herbal vapor may be collected into a bag and/or canister for subsequent consumption.

A hand-held, portable inhalator device is disclosed. The device has a mouthpiece with a chamber operatively coupled to a medication inlet and a fluid outlet. A trigger is configured to dispense medication from a medication source through the medication inlet and into the chamber after a threshold level of positive pressure is achieved within the chamber of the mouthpiece and maintained for a threshold period of time.
