A medication inhalation apparatus includes an outer housing, movable between collapsed and expanded states, encompassing a first volume. An inner housing within the outer housing encompasses an inner volume. An inhaler opening to the first volume is within a wall of the outer housing at a first location. A mouth opening to the inner volume is within a wall of the outer housing and the inner housing at a second location. A one-way inhalation valve connecting the first volume and the inner volume is within a wall of the inner housing. A one-way exhalation valve connecting the inner volume and the exterior of the outer housing is within a wall of the outer housing and inner housing at a third location. In the expanded state, gas flows from the inhaler to the first volume, the first volume to the inner volume, and the inner volume to a user's mouth.

A stable-foam inhalation-device cartridge for a stable-foam inhalation device which dispenses a stable foam to be consumed by a user. The cartridge is devoid of an electrical energisation component. The cartridge includes a flexible mixing chamber, first and second foam-generation elements, an expansion chamber, a partitioning element having one or more mixing members for agitating a consumable foam and a discharge element. The discharge element has an outlet opening an inlet opening and a discharge conduit which interconnects the inlet opening with the outlet opening. The discharge conduit has a longitudinal extent which locates the inlet opening at a position closer to the partitioning element than to the outlet opening.

An accessory device for delivering medications from press and breath metered-dose inhalers (pMDIs), including those medications containing hydrofluoroalkane propellants. The device includes a collapsible flexible bag to which is attached a bidirectional mouthpiece and an adaptor that receives the press and breath MDI. The mouthpiece contains a reed that functions as an audible signal, and a screen to prevent inhalation of unwanted particles. The adaptor positions the press and breath MDI at an angle to direct the aerosol spray toward the center of the collapsible flexible bag. When the press and breath MDI is triggered, it discharges the aerosolized medication into the center of the collapsible flexible bag which is then inhaled by the user through the mouthpiece. This collapses the bag. The reed emits an audible sound if the user inhales above a pre-determined flow rate to maximize medication delivery and ensure dose-to-dose consistency.

An herb vaporizing apparatus includes an herb receiving port, a grinder to grind the herb, and a heating chamber for heating the ground herb to create a vapor. A first end of the heating chamber is positioned closer to a top of the apparatus than a second end of the heating chamber, such that the ground herb generally moves in at least a partially downward direction as it travels through the heating chamber. The apparatus further includes a screw feeder positioned within the heating chamber that rotates and moves the ground herb within the heating chamber. The apparatus further includes an air pump for pumping vapor out of the heating chamber and a valve positioned along an airway between the heating chamber and a vapor output. The valve permits air and the vapor to move from the heating chamber to the vapor output only while the air pump is activated.

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.

An improved spacer connects at one end to metered-dose inhalers with a connector configured to accept the mouth of the inhaler. Additionally, the spacer has a mouthpiece at its opposite end and a collapsible body made of a nonrigid material that maintains it shape with a resilient frame. The mouthpiece and body compress and nest within a cavity of the connector when the spacer is not in use. The spacer can further include a cover, a case, a vent to improve airflow, and/or a valve to cover the spacer to a valved holding chamber.

A hollow extension tube or extension assembly aids in increasing the quantity of any inhaled or aerosolized substance delivered to a patient's lungs from an inhaler or source. The length of the extension tube reduces the velocity and increases the temperature of the aerosolized substance, easing inhalation. The interior surface of the hollow extension tube has anti-static properties which reduces the amount of aerosolized substance trapped by the interior surface of the hollow extension tube. The interior surface of the extension tube may be formed of cardboard.

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.

A vapor blending device is provided, generally having a base, a carrier removably couplable to the base for carrying a first and second vapor generating system. The first and second vapor generating systems including airflow generators and controllers configured to vary voltage to each of the first and second vapor generating devices and the airflow generators. A container is positioned in fluid communication with the first and second vapor generating systems and configured to retain a quantity of vapor. In some examples, one controller is configured to cause the first vapor generating system to generate a quantity of a first vapor, and another controller is configured to cause the second vapor generating system to generate a quantity of a second vapor in a predetermined ratio to the quantity of the first vapor. The vapor in the predetermined ratio is stored in the container for later removal.
