摘要:
Deformable valves and atomizer designs for a vaporizer (e.g., electronic cigarette). The vaporizer may be used for vaporization of liquid and/or organic material. The vaporizer may enable enhanced flow control of fluid and may generate high quality and quantity of vapor efficiently. In some instances, flow path of the vaporizer may allow bulk fluid flow, e.g., in contrast to capillary flow, to deliver fluid to a vicinity of the vaporizer. In some instances, the vaporizer may utilize improved atomizer designs for vaporizing devices, where said designs can be configured optionally, with various embodiments of a breath-modulating deformable valve.

An inhaler, preferably for insertion into a nostril, in particular a horse's nostril, with a pressure generator, which has a tensioning device for the drive, and with a tensioning mechanism for tensioning the tensioning device, whereby the tensioning mechanism has a lever gear for tensioning the tensioning device.
摘要:
A pressurized refill canister containing a composition including a propellant. The canister has an outlet valve having a stem biased to a closed position by a first resilient member. The stem has a maximum outer diameter of greater than 3 mm. At the outlet end of the stem, at least part of the wall of the stem extends inwardly from the outside diameter for at least 50% of the radius.
摘要:
The present invention provides a cannabinoid inhaler, compositions, and methods for delivering a cannabinoid composition to a subject. The cannabinoid composition is delivered in the form of inhaled droplets of respirable size via pulmonary administration. The invention may be used in the treatment of a condition or disorder selected from the group consisting of neuropathic pain, cannabis addiction, nausea, motion sickness, arthritis, and neurodegenerative disease.
摘要:
This invention relates to an inhaler with a respiration indicator, whereby the inhaler has a chamber wall forming a chamber and a dispensing device for fluidic connection of the chamber to a bodily opening, preferably a nostril, whereby the respiration indicator has a wall section of the chamber wall or is formed in this way, whereby the wall section is designed to indicate a respiratory activity by deformation and/or movement.
摘要:
A method of delivering a therapeutic agent comprises providing an aerosol generator that produces an aerosol of particles or droplets containing a therapeutic agent and an excipient for delivery to a first portion of a respiratory tract. The particles or droplets have an initial diameter from about 1 μm to about 8 μm, and the initial momentum of the particles or droplets minimizes deposition in the first portion. The particles or droplets are exposed to relative humidity in the respiratory tract by delivering them at a flow rate that defines the residence time in the respiratory tract. The particles or droplets increase in diameter due to hygroscopic growth caused by relative humidity. The aerosol is nasally exhaled so that particles or droplets are delivered to the nasal cavity and deposited in the nasal turbinates or sinus in part because of their increased diameter.
摘要:
Systems and methods are provided for aerosolizing and delivering therapeutic substances in an electronic aerosol delivery device with airflow regulation. Calibrated airflow resistance settings enable adjustment and control of flow velocity and or flow volume of air, aerosolized air, and or entrained aerosol particles, through the device, for optimal aerosol delivery among diverse conditions and applications.
摘要:
An assembly and methods for providing a contoured biological tissue are described. The assembly comprises a first plate and a second plate. The first plate is configured to receive a biological tissue. The second plate is configured to apply a compressive force on the biological tissue that is disposed on the first plate. One or both of the first and second plates comprise a defined shape and a contoured area within the defined shape. The contoured area comprises at least first and second elevations and a continuous transition between the first and second transitions. One or more energy sources is associated with one or both of the first and second plates. The one or more energy sources delivers energy while the second plate applies the compressive force on the biological tissue disposed on the first plate.
摘要:
An inhaler comprising a reservoir of an inhalable composition with an outlet at one end through which the inhalable composition is discharged. A non-metered breath-activated valve is provided between the one end and the reservoir, the breath-activated valve comprising a flow path extending from the reservoir to the outlet end. At least a portion of the flow path is a deformable tube. A clamping member pinches the deformable tube closed when no suction force is applied to the device and releases the tube to open the flow path when suction is applied at the outlet, to provide uninterrupted flow from the reservoir to the outlet.
摘要:
A device for delivering a predetermined volume a substance within a body cavity. The device includes: at least one predefined volume sized and shaped to contain a predetermined volume the substance; a delivery end in fluid communication with a container; and at least one valve mechanically connected to the container and configurable between an active configuration in which the valve enables delivery of a volume of the substance and an inactive configuration, in which the valve prevents delivery.
