A novel dry powder inhaler. By providing a plurality of capsule chambers (1a, 1b, 1c, 1d) arranged in parallel in a capsule dry powder inhalation device, a medicine dispenser containing active components of a composite product or their mixture separately is provided. The dry powder inhaler has a simple structure and is convenient to operate. In addition, the parameters of air inlet channels and an air outlet channel can be adjusted by means of each capsule chamber (1a, 1b, 1c, 1d) according to the properties of powder of a medicine or a combination, so as to provide an appropriate particle distribution for each active component.

This invention relates to an inhalation device by which a user can inhale powdered pharmaceutical compositions or medications. Powdered medication is held in blister packs containing at least one or two separated pockets for two or more active pharmaceutical ingredients and is inhaled by users through inhalation devices. The invention also relates to an inhalation device for powdered pharmaceutical compositions comprising a medication blister pack containing two separated pockets to hold two active pharmaceutical ingredients, an opening station, and an outlet, the blister pack comprising two pockets for powdered medication contained between two members peelably secured to one another.

A multi-dose dry powder inhaler with a blister folding device is provided. The inhaler comprises a housing containing a blister strip, and a blister opening device. The blister strip comprises a plurality of individual blisters, each blister containing a dose of medicament for inhalation by a user. The blister opening device comprising a blister support element for supporting one of said blisters, and a blister folding element co-operable with the blister support element, the blister folding element and the blister support element being movable relative to each other between a first position, permitting movement of said blister into or onto the blister support element, and a second, burst, position in which the blister folding element has co-operated with the blister support element. Movement from the first position to the second position causes two spaced apart portions of said blister to each fold relative to the remainder of the blister to produce two spaced apart openings, each opening extending along the circumference of the blister bowl, beginning and terminating at points located on the fold line No piercing of the blister at any stage is required.

A heating unit comprising an electrically conductive substrate. A solid fuel layer comprising a metal reducing agent, a metal containing oxidizing agent and a binder is coated on a surface of the substrate, the solid fuel layer having a solid fuel surface spaced from the substrate. A first electrode coupled to the substrate. A second electrode coupled to the solid fuel surface. A power supply is configured to be selectively coupled to the first and second electrodes to provide a voltage between the metallic substrate and the solid fuel surface. The voltage acts to propagate an exothermic metal oxidation-reduction reaction without the use of an igniter.

A dry-powder inhaler may include a first casing portion, a second casing portion, and a hinge arrangement connecting the first casing portion and the second casing portion. The dry-powder inhaler may be assembled by folding the first casing portion and the second casing portion together. The first casing portion may include a cavity for receiving a dose blister foil, said cavity being adapted to contain a dry-powder medicament. The first casing portion and the second casing portion when folded together may be adapted to form an inlet for allowing a lidding foil extending out there from and an outlet for providing the medicament.

A method of purifying herbal extract(s) from an herbaceous plant composition includes heating the herbal extracts-containing composition to volatilize at least one of herbal extract(s) into a vapor and condensing the vapor on a substrate or wet extracting the herbal extract(s) by treatment of the herbaceous plant composition or a derivative thereof with a solvent for the herbal extract(s), separating the solution of herbal extract(s), forming a concentrate and casting the concentrate on the substrate to form a coating of the herbal extract(s) on the substrate. A corresponding delivery cartridge and delivery system can include a controllable heating element and the substrate coated with at least one of herbal extract(s). These are configured to allow passage of air over the substrate to volatilize or entrain the herbal extract(s) as a vapor, gas or aerosol for administration to a user.

A method for controlling a vaporizer device may include determining a first temperature, vaporizing an inhalable substance at the first temperature, raising the first temperature by a temperature quantity, wherein a second temperature is a sum of the temperature quantity and the first temperature; and vaporizing the inhalable substance at the second temperature, wherein the temperature quantity is less than 3 C.

A fluid dispenser device with a main body (10); a reservoir (21) containing a dose of powder; a reservoir opening mechanism (80); a dispenser orifice (5); a movable support mechanism (50) to displace a reservoir (21) against the opening mechanism on actuation and displaceable between a non-dispensing position and a dispensing position, urged towards the dispensing position, and held in the non-dispensing position by a blocking mechanism (100). An inhalation trigger system (60) is provided that has a deformable air chamber (61) and a trigger element (600) that co-operates firstly with the air chamber (61) and secondly with the blocking mechanism. The fluid dispenser device further includes an electronic dose counter or indicator device (300) including a sensor (306) to detect displacement or deformation of a portion of the fluid dispenser device, generated while the user is inhaling or after the user has inhaled.

A method of purifying herbal extract(s) from an herbaceous plant composition includes heating the herbal extracts-containing composition to volatilize at least one of herbal extract(s) into a vapor and condensing the vapor on a substrate or wet extracting the herbal extract(s) by treatment of the herbaceous plant composition or a derivative thereof with a solvent for the herbal extract(s), separating the solution of herbal extract(s), forming a concentrate and casting the concentrate on the substrate to form a coating of the herbal extract(s) on the substrate. A corresponding delivery cartridge and delivery system can include a controllable heating element and the substrate coated with at least one of herbal extract(s). These are configured to allow passage of air over the substrate to volatilize or entrain the herbal extract(s) as a vapor, gas or aerosol for administration to a user.

A respiratory system and method comprise a tracker module adaptable to be secured to a variety of inhalers, the tracker module sensing activation of the medication canister of the inhaler for delivery of medication to a user. The tracker module also senses the rate of inhalation air flow of the user when inhaling medication for determination of proper inhaler use. Upstream and downstream sensors provide flow information to determine quality of the inhalation. Other sensors are provided that monitor user presence at the inhaler, user technique in using the inhaler, and the attitude of the inhaler when it was used. Low power devices are used to conserve battery power.
