Inhaler to deliver substances for prophylaxis or prevention of disease or injury caused by the inhalation of biological or chemical agents
A dry powder inhaler may include a powder storage region, an inlet channel, a dispersion chamber, and an outlet channel. A geometry of the inhaler may be such that a flow profile is generated within the dispersion chamber that causes an actuator to oscillate, enabling the actuator when oscillating to deaggregate powdered medicament within the dispersion chamber to be aerosolized and entrained by the air and delivered to a patient through the outlet channel.
LIQUID DRUG CARTRIDGES AND ASSOCIATED DISPENSER
Liquid drug cartridges and an associated inhaler are used to deliver one more separate doses of an aerosolized liquid drug. A cartridge includes a container for storing the liquid drug, an end cap having an ejection opening, a filter element, and a piston that is repositionable relative to the container to selectively eject a volume of liquid drug from the ejection opening. The filter element filters the liquid drug prior to ejection from the ejection opening. The liquid drug cartridge can be coupled with an inhaler that includes an aerosol generator. The aerosol generator includes a vibratable membrane onto which the liquid drug is ejected. The liquid drug is aerosolized by the vibration of the membrane for inhalation by a user.
THERMAL MODULATION OF AN INHALABLE MEDICAMENT
A thermally modulating inhalable medicament delivery device may deliver an inhalable medicament as an aerosol, vapor, or partial aerosol and partial vapor mixture. The inhalable medicament may be delivered to a target in a subject. Described herein are devices, systems, and methods for delivering an inhalable medicament to a subject.
Powder dispersion devices and methods
A dry powder inhaler may include a powder storage, an inlet channel, a dispersion chamber, and an outlet channel. A geometry of the inhaler may be such that a flow profile is generated within the dispersion chamber that causes an actuator to oscillate, enabling the actuator when oscillating to deaggregate powdered medicament within the dispersion chamber to be aerosolized and entrained by the air and delivered to a patient through the outlet channel.
Capsule having a liquid transporting element for uses with an electronic smoking device
A capsule for use with an electronic smoking device includes a shell (105) having a lateral wall (101, 102) and an end wall (103), wherein the lateral wall (101, 102) and the end wall (103) defines a cavity (110) open at one end (111). A puncturable membrane (104) seals the open end (111) of the cavity (110). A liquid is contained within the cavity (110) by the shell (105) and the puncturable membrane (104), wherein a liquid transporting element (120) is arranged within the cavity (110) enclosed by the puncturable membrane (104) and immersed in the liquid.
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.
Aerosolization apparatus with air inlet shield
An aerosolization apparatus comprises a housing defining a chamber having a plurality of air inlets. The chamber contains an aerosolizable pharmaceutical formulation or is sized to receive a receptacle which contains an aerosolizable pharmaceutical formulation. A shield covers at least one of the air inlets or a portion of at least one of the air inlets. The shield prevents blockage of the air inlet by a user grasping the apparatus and inadvertently covering the air inlet. An end section is associated with the housing. The end section is sized and shaped to be received in a user's mouth or nose so that the user may inhale through the end section to inhale aerosolized pharmaceutical formulation that has exited the receptacle.
Liquid drug cartridges and associated dispenser
Liquid drug cartridges and an associated inhaler are used to deliver one more separate doses of an aerosolized liquid drug. A cartridge includes a container for storing the liquid drug, an end cap having an ejection opening, a filter element, and a piston that is repositionable relative to the container to selectively eject a volume of liquid drug from the ejection opening. The filter element filters the liquid drug prior to ejection from the ejection opening. The liquid drug cartridge can be coupled with an inhaler that includes an aerosol generator. The aerosol generator includes a vibratable membrane onto which the liquid drug is ejected. The liquid drug is aerosolized by the vibration of the membrane for inhalation by a user.
Thermal modulation of an inhalable medicament
A thermally modulating inhalable medicament delivery device may deliver an inhalable medicament as an aerosol, vapor, or partial aerosol and partial vapor mixture. The inhalable medicament may be delivered to a target in a subject. Described herein are devices, systems, and methods for delivering an inhalable medicament to a subject.
Source material cartridge with temperature-controlled sealant
According to some embodiments there is provided a device configured for releasing at least one substance from source material, comprising: a housing; a plurality of source material sections positioned at fixed locations with respect to the housing; a plurality of airflow paths, each airflow path associated with at least one source material section; each airflow path associated with at least one blocking element which prevents flow of air through the path; and an actuator operably coupled to the blocking element, the actuator configured for unblocking the airflow path of at least one selected source material section to allow flow of air to and through source material within the selected section.
