An incentive inhaler device includes an inhalation device, at least one incentive toy coupled to the inhalation device, and at least one separator. The inhalation device has a respiration device and a connector that is linkable to a delivery device. The delivery device can deliver drugs, aerosols, powder and gas. The incentive toy is respiration driven and has at least one of a visible characteristic and an audible characteristic. The separator decouples the toy from at least one component of the inhalation device to ensure directional flow of respirational air which drives the toy. The separator can include a valve, a filter, or a baffle.

The present invention relates to concentrates obtained from extraction from Cannabis, preferably cannabinoid and/or terpene concentrates, and formulation of the concentrates, particularly for use for direct vaporization, infusion into edible matrices, in electronic inhalation devices, and as nutraceuticals.

Aerosol formulations suitable for use in pressurised metered dose inhalers comprise a hydrofluoroalkane propellant, an medicament for inhalation and a surfactant which is a a C₈–C₁₆ fatty acid or salt thereof, a bile salt, a phospholipid, or an alkyl saccharide.

A non-burning type flavor inhaler includes an aerosol source that generates an aerosol; an atomizer that atomizes the aerosol source without burning; a power source that supplies power to the atomizer; a light-emitting element; and a control unit that controls the light-emitting element. The control unit controls the light-emitting element in a first light-emitting mode in a puff state inhaling the aerosol, and controls the light-emitting element in a second light-emitting mode different from the first light-emitting mode in a non-puff state not inhaling the aerosol. The second light-emitting mode changes according to a number of puff actions for inhaling the aerosol.

An aerosol solution composition for use in an aerosol inhaler comprises an active material, a propellant containing a hydrofluoroalkane, a cosolvent and optionally a low volatility component to increase the mass median aerodynamic diameter (MMAD) of the aerosol particles on actuation of the inhaler. The composition is stabilized by using a small amount of mineral acid and a suitable can having part or all of its internal metallic surfaces made of stainless steel, anodized aluminium or lined with an inert organic coating.

To provide an inhalation device which has improved use properties, particularly advanced moisture protection while in use, an inhalation device (1) for powder drugs is proposed comprising at least one storage chamber (13) for accommodating a plurality of drug powder doses and a dosing device which includes at least one dosing slider (15) which is movable approximately with a translatory movement in a dosing slider passage (16) at least from a filling position into an emptying position, wherein the inhalation device (1) further includes a device for inhalation-triggered automatic movement of the dosing slider (15) from its filling position into the emptying position and a return device for automatic movement of the dosing slider (15) back into the filling position.

The inhalation therapy assembly and method of use described herein increases the efficiency of metered dose inhalers by allowing delivery of the doses to a collapsible reservoir which can be manually pumped, ensuring that medicants contained therein are properly and completely delivered to the patient. Terminal and proximal valves of the one-way diaphragm type allow flow of the aerosol medicants while preventing improper expulsion. An exhalation valve is adjustable to ensure the patient exhales suitably to permit proper medicant absorption. A conventional metered dosage inhaler having an approved FDA canister provides proper dosage to the patient and is joined to the collapsible reservoir by a connector having a plurality of apertures for receiving the MDI and an accessory T-fitting.

The present invention is directed to a device for monitoring the usage of inhaled drugs by a patient. The device includes an inhaler, a use sensor, a microprocessor, a wireless transmitter and a battery compartment. These components allow information concerning drug usage to be transmitted to health care personnel that can evaluate the data to determine whether there are changes in drug usage characteristics that are indicative of an impending acute attack. The invention includes not only the device, but also the systems and methods in which the device is employed.

A composition for modifying a surface of a substrate, the composition comprising: (a) a first polyfluoropolyether silane of the Formula Ia: CF₃CF₂CF₂O(CF(CF₃)CF₂O)_pCF(CF₃)—C(O)NH(CH₂)₃Si(Y)₃ wherein each Y is independently a hydrolyzable group and wherein p is 3 to 50; and (b) a second polyfluoropolyether silane of the Formula IIa: (Y′)₃Si(CH₂)₃NHC(O)—CF₂O(CF₂O)_m(C₂F₄O)_qCF2-C(O)NH(CH₂)₃Si(Y′)₃ wherein each Y′ is independently a hydrolyzable group and wherein m is 1 to 50 and q is 3 to 40. A method of making a medicinal inhalation device or a component of a medicinal inhalation device comprising a step of applying to at least a portion of a surface of the device or the component, respectively, the composition.

The present invention provides a system and method for determining and maintaining a concentration level of medication in a patient sufficient to achieve and maintain a desired effect on that patient. Generally speaking, in accordance with one embodiment of the invention, a medication delivery controller uses a patient response profile to determine a concentration of medication in the patient that will achieve the desired effect on the patient. The patient response profile is a graphical, tabular or analytical expression of the relationship between the concentration of a medication and the effect of the medication at the specific concentration. Using this information, the medication delivery controller provides instructions to a medication delivery unit such as, for example, an infusion pump or inhalation device, to deliver the medication to the patient at a rate that will achieve the desired concentration level of the medication in the patient.

Engineered particles are provided may be used for the delivery of a bioactive agent to the respiratory tract of a patient. The particles may be used in the form of dry powders or in the form of stabilized dispersions comprising a nonaqueous continuous phase. In particularly preferred embodiments the particles may be used in conjunction with an inhalation device such as a dry powder inhaler, metered dose inhaler or a nebulizer.

A collapsible inhalation device for use with a metered dose inhaler (MDI) dispenser includes an outlet end member, an inlet end member and a tubular, pliable, collapsible sleeve member attached at either end to the inlet and outlet members. The outlet end member includes a mouthpiece. The inlet end member includes an inlet port and an MDI dispenser mount structure configured to receive and engage the MDI dispenser. The inhalation device is positionable in each of an open position, wherein the sleeve member defines a chamber, and a closed position, wherein the sleeve member is collapsed and enveloped by the outlet end member and the inlet end member. When the inhalation device is in the open position with the MDI dispenser mounted in the MDI dispenser mount structure, a dose of the medication can be dispensed from the MDI dispenser into the chamber through the inlet port to mix with air in the chamber and thereby form a mixture of the air and the dose of the medication that can be inhaled by a patient from the chamber through the mouthpiece.

An inhalation device for the uptake of medicaments that are in the form of dry powder contained in the blisters of specially designed single dose blister strips. The device is comprised of a mouthpiece (A), a strip support surface area (B). and one or more storage areas (C). Furthermore, the single dose blister strip is described. It is comprised of two sheets (17, 20) that are fixed in such a manner so that when they get separated the powder becomes available for inhalation.

A device having a first chamber for filtering smoke or vapor prior to inhalation of the smoke or vapor. A second chamber contains a substance to be heated or burned. A heating or burning plate is configured to heat or burn the contained substance to produce the smoke or vapor and a stirring component is configured for stirring and redistributing the substance while being heated or burned. A one-way valve passes the smoke or vapor in one direction, from the second chamber to the first chamber and prevent leakage of the smoke or vapor within the first chamber.
