  • Patent number: 11672927
    Abstract: The present invention provides for the integration of drug dispersion methods into a drug or medicine delivery system. The drug dispersion methods used include shear (e.g., air across a drug, with or without a gas assist), capillary flow or a venturi effect, mechanical means such as spinning, vibration, or impaction, and turbulence (e.g., using mesh screens, or restrictions in the air path). These methods of drug dispersion allow for all of the drug in the system to be released, allowing control of the dosage size. These methods also provide for drug metering, fluidization, entrainment, deaggragation and deagglomeration. The present invention also provides for the integration of a drug sealing system into the device. The drug sealing system provides a way of blocking the migration of drug from one area of the package to another.

    Abstract: An inhalation delivery device for dry powder with adjusting resistance through detachable heads, which combines four different detachable heads and uses a single base. The desired resistance and the medicament delivery/allocation to the lungs, are set, offering a practical, low cost solution while, at the same time, a high performance personalized treatment. The detachable head (1) comprises a mouthpiece (2) for the mouth of the patient, a medicament intake orifice (3) sized to fit into the mouth of a patient and a protrusion (4) for a sliding connection between the detachable head (1) and the base (5), via notches (6) carried by the base (5). Each detachable head (1) possesses a corresponding protrusion (4) which may be fitted onto the base (5). The device comprises typically four different heads (1), covering the entire spectrum of patients accordingly to their inhalation capacity, the medicament type/dose and the targeted point of treatment.

  • Patent number: 11291781
    Abstract: An inhaler device for pulmonary delivery of at least one substance from a drug dose cartridge to an inhaling user, including: a first conduit for conducting a carrier airflow to a proximal opening of a mouthpiece for use by the user; a holder configured to position the dose cartridge within the carrier airflow; and a second conduit for conducting a shunting airflow to the mouthpiece without passing through the dose cartridge position. In some embodiments, a controller connected to a valve controls a rate of carrier airflow, for example by controlling the shunting airflow, based on a sensor indication of airflow rate and a target airflow profile.

  • Patent number: 11241039
    Abstract: The split airflow system for an electrically heated smoking system for generating aerosol, the split airflow system having a downstream end comprises a first channel defining a first flow route and a second channel defining a second flow route. The first flow route directs ambient air from outside the system to the downstream end of the system. The second flow route directs ambient air from outside the system towards a preferably substantially flat, fluid permeable, heating element before conveying the ambient air to the downstream end. The first channel and the second channel define a total volume of ambient air passing through the system and the first channel provides at least 50 percent of the total volume of ambient air passing through the system. The invention also refers to a method for guiding an airflow in an electrically heated smoking system for generating aerosol and an electrically heated smoking system comprising the split airflow system.

  • Patent number: 11229757
    Abstract: A dry powder inhaler dispenses a partial dosage of a powder from a dry powder chamber during a single user inhalation. In certain embodiments, the dry powder chamber is a dry powder capsule that spins in a chamber with a protrusion for limiting the spin of the capsule. In certain embodiments, a capsule slides in a proximal and distal direction for dispensing partial dosages of powder medicament. Air inlets in communication whit the external environment can be included in the inhaler housing for generating a smooth inhalation experience for the user and facilitating operation of partial dosage mechanisms. In other embodiments, a hinged member, sliding member, rotating member, spring tensioned member, pressure actuated valve, dry powder chamber with patterned holes or combinations of these are used as a mechanism for dispensing a partial dosage of powder medicament during a single inhalation.

  • Patent number: 11224704
    Abstract: Methods and devices for delivering a dose, such as a medicament, for inhalation. A dose may be stored by a delivery device and dispersed and delivered in a metered fashion to a subject, such as by the subject inhaling via a mouthpiece of the delivery device. One or more chambers of the device may have a toroidal shape and may be arranged to be selectively opened for fluid communication with a flow path of the delivery device, such as by sliding the chamber relative to a portion of the flow path. The flow path may include a restriction that permits air to bypass the chamber, and/or the chamber may be arranged so that fluid entering the chamber interacts with fluid exiting the chamber so as to enhance dispersion of the dose.
