A stand-alone chamber or multi-chamber inhalation system has at least two alternative vaporized test liquid supply systems for passive or self-administered delivery of vaporized test fluid and air to one or more test chambers, which can be passive or restraint chambers, based on operator selection of delivery on and off times in a passive mode or actuation of an actuator in the chamber by a test animal in a self-administered mode. In one case, a multiple inhalation chamber system has two or more separate test fluid delivery systems and provides options for selective passive uniform drug delivery to multiple chambers or selective delivery of two or more different drugs to different groups of chambers from different delivery systems so that two different drugs or different concentrations of delivered drugs can be tested simultaneously.

A dry powder inhaler including replaceable cartridges containing a dry powder for local or systemic delivery through the pulmonary tract and lungs is disclosed. The inhalers are used with inhalable dry powders, including medicament formulations comprising active agents for local or systemic delivery and for the treatment of diseases such as, pulmonary hypertension, cardiovascular disease, anaphylaxis, diabetes, obesity, cancer, and other diseases, or symptoms associated with these and other diseases, such as nausea, vomiting, pain and inflammation.

A nasal delivery device for delivering substance to a nasal cavity of a subject, the delivery device comprising: a substance supply unit for supplying a dose of substance to be delivered to the nasal cavity of the subject, the substance supply unit including an inlet and an outlet; a nosepiece unit including a nosepiece for fitting to a nasal cavity of the subject and being in fluid communication with the outlet of the substance supply unit; and a mouthpiece unit including a mouthpiece in fluid communication with the inlet of the substance supply unit and through which the subject in use exhales such as to entrain substance from the container chamber and deliver the same through the nosepiece, and at least one temperature modifier for reducing a temperature of the exhaled air flow such as to reduce the absolute humidity thereof.

A dry powder delivery device may be configured to provide micronized dry powder particles to airways of a user. The device may include a cylindrical container delimiting a chamber containing at least one magnetically-responsive object, a motor external to said chamber, a magnet external to the chamber and rotatably coupled with the motor, and an outflow member configured to direct airflow to a user. The magnetically-responsive object may be coated with micronized dry powder particles, and the motor may be operable to rotate the magnet about an axis. Rotation of the magnet creates a magnetic field that causes the magnetically-responsive object to move in response to the magnetic field and collide with a side wall of the container to deaggregate the dry powder particles and aerosolize the dry powder in the chamber.

A device for delivering a compound to the olfactory region of the nasal cavity includes an actuator body and a tip configured to removably couple to the actuator body. The actuator body comprises a propellant channel in fluid communication with a propellant canister. The tip comprises a tip stem, a dip tube, a delivery channel, one or more puncture members, and an outlet orifice. The tip stem receives a compound container containing the compound and the compound container moves between a sealed state and an unsealed state. The one or more puncture members are each configured to puncture the compound container when the compound container is in the unsealed state. Propellant released from the canister travels through the propellant channel and into the punctured compound container, thereby contacting the compound and propelling the compound through the delivery channel and out the outlet orifice.

Provided is a blister pack for a dry powder inhaler, which dry powder inhaler is configured to deliver a first powder medicament and a second powder medicament different from the first powder medicament. The first and second powder medicaments are contained within blister pockets defined in a strip. A series of blister pockets is defined in the strip, which series extends linearly along the length of the strip. The first and second powder medicaments are contained in blister pockets, e.g. respective blister pockets, of the series. Alternatively or additionally, each of the blister pockets is elongated such as to have a largest dimension parallel with the length of the strip. These measures, either individually or in combination, enable minimizing of the width of the strip in spite of the strip accommodating both the first and second powder medicaments. This, in turn, may enable the depth/thickness of the dry powder inhaler to be minimized, and/or additional space to be provided inside the dry powder inhaler for accommodating, for example, use detection and wireless connectivity electronics for sending use detection data to an external device, such as a smartphone.

Disclosed are dry powder inhalers for delivering medicament to a user from a blister pack, the blister pack having a plurality of spaced-apart blister pockets containing doses of the medicament. The inhalers comprise: a housing for accommodating unused and used portions of the blister pack together with a dispensing mechanism for selectively opening the blister pockets; and a manifold component through which air can be drawn in use of the inhaler. The manifold component comprises: a primary air inlet opening for receiving first external air; an air outlet opening for providing the external air from the primary air inlet opening into an opened blister pocket, the primary air inlet opening being fluidly connected to the air outlet opening by a primary air delivery conduit formed in the manifold component; a medicament inlet opening for receiving air-entrained medicament from the opened blister pocket, the air outlet opening and the medicament inlet opening being arranged side-by-side to enable simultaneous communication with the opened blister pocket; and a medicament outlet opening for delivery of the air-entrained medicament from the opened blister pocket to the user, the medicament inlet opening being fluidly connected to the medicament outlet opening by a medicament delivery conduit formed in the manifold component. The disclosed inhalers embodiments provide a variety of improvements to the design of the manifold component.

The invention relates to a mouthpiece for a product dispensing device including a product dispensing duct defining a longitudinal axis and including a connection opening designed to be connected to a dispensing member of the product dispensing device, and a dispensing opening designed to open freely into the mouth of a user, and a lingual cavity designed to receive at least one end of the tongue of the user, including a lingual opening allowing the tongue to be inserted into the lingual cavity and a contact surface designed to form a target for one end of the tongue of the user.

The invention also relates to a product dispensing device and to a method for dispensing a product.

Systems and methods are provided for delivering one or more drugs. In some embodiments, a drug delivery system includes a housing having a distal end with an inlet through which an inspiratory flow of air passes into the housing, a proximal end having a patient interface attached thereto, the patient interface being configured to interface with a user, and an inspiratory flow pathway extending from the distal end to the proximal end of the housing. A nitric oxide (NO) source is positioned within the housing and is configured to deliver NO-containing gas to the patient interface. A secondary drug source is positioned within the housing and is configured to deliver a secondary drug to the patient interface. A controller is configured to control an amount of NO-containing gas and an amount of the secondary drug delivered using a control scheme.

Devices, cartridges, and method are described herein for emulating smoking wherein a device generates an aerosol for inhalation by a subject by heating a viscous material that can have a tactile response in the mouth or respiratory tract, while reducing Hoffman analytes and mutagenic compounds delivered to the user as compared to a common tobacco cigarette.
