Electronic device for producing an aerosol for inhalation by a person
11690963 · 2023-07-04 · ·

An electronic device for producing an aerosol for inhalation by a person includes a mouthpiece, a liquid container, and a mesh assembly having a mesh material and a piezoelectric material. The mesh material is in contact with a liquid of the container. The mesh material is configured to vibrate when the piezoelectric material is actuated, whereby the aerosol is produced. The aerosol may be inhaled through the mouthpiece. The device also includes circuitry and a power supply for actuating the mesh assembly. The mouthpiece, the container, and the mesh assembly are located in-line along a longitudinal axis of the device between opposite longitudinal ends of the device, with the mesh assembly extending between and separating the mouthpiece and the container. The mesh material has a rigidity that is sufficient to prevent oscillations of varying amplitudes during actuation of the piezoelectric material of the mesh assembly for consistently producing the aerosol.

POWDER DISPERSION METHODS AND DEVICES

A dry powder inhaler includes a powder storage element configured to hold a powdered medicament and an inlet channel receives, powdered medicament from the powder storage element that is entrained in an airflow. The inlet channel has a first diameter and defines an opening. The inhaler includes a dispersion chamber that receives the airflow and the powdered medicament from the opening. The dispersion chamber has a second diameter. The inhaler includes an actuator housed within the dispersion chamber. The actuator oscillates within the dispersion chamber when exposed to the airflow to deaggregate the powdered medicament entrained by the airflow passing through the dispersion chamber. A ratio between the first diameter and the second diameter is between about 0.40 and 0.60 such that an audible sound is produced as the actuator oscillates. The inhaler includes an outlet channel through which the airflow and powdered medicament exit the inhaler.

Counting mechanism
11544520 · 2023-01-03 · ·

A counting mechanism (100) for a dispenser comprising: a first and a second housing part (110, 120) that are rotatable relative to each other; and a counting ring (130) disposed between the housing parts. The first housing part has a protrusion (111) which abuts the counting ring, holding a portion of the counting ring in contact with the second housing part. The relative rotation of the housing parts causes the protrusion to slide against the surface of the counting ring to drive a rolling movement of the counting ring around the circumference of the second housing part, such that a predefined rotation of the housing parts produces an incremental rotational displacement between the counting ring and second housing part to record a count. The counting mechanism provides a large gear reduction ratio in a compact form which is straightforward to manufacture and provides an accurate and reliable record of counts.

PORTABLE VAPORIZING DEVICE, CARTRIDGE AND METHODS
20250228298 · 2025-07-17 ·

A portable vaporizing device and/or cartridge comprises a product chamber capable of holding a vaporizable product therein, and a porous valve element configured to be heated to flow the vaporizable product therethrough and generate vapor from the vaporizable product, and optionally including a heat transfer element to heat the vaporizable product as it flows through the product chamber towards the porous valve element.

INHALATION DEVICE
20250229042 · 2025-07-17 ·

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. The drug seal system can also provide a method of tightly containing the drug until the package is opened, of directing airflow through the package and of managing and containing the drug during the package/device manufacturing process.
