Provided is a system including a plurality of inhalers that each include a processor configured to determine a value of a usage parameter relating to use of the respective first inhaler, encrypt data based on the value, and transmit the encrypted data. At least two of the inhalers include different medicament, such as a rescue medicament and a maintenance medicament. The system includes an external device that includes a processor configured to distinguish between the encrypted data of each respective inhaler, determine respective usage information relating to each of the distinct types of medicament based on the respective encrypted data, and control a user interface (e.g., of the external device) to communicate the usage information related to each inhaler and/or each respective type of medicament.

This invention relates to a fixed-dose dry powder inhalation formulation comprising fluticasone propionate and albuterol sulfate, together with an α-lactose monohydrate carrier. In the formulation, the albuterol sulfate stabilises fluticasone propionate.

Disclosed is a drug vaporization and inhalation device. The present invention is configured such that when an infected patient with asthma, a coronavirus, or the like inhales a particulate drug, the drug is contained in vaporized steam, and therefore, the drug can sufficiently arrive at the lungs of the infected patient with asthma, a coronavirus, or the like, without loss, thereby preventing a given amount of the drug from remaining in an inhalation container and improving the drug inhalation efficiency of the infected patient with asthma, a coronavirus, or the like along with prevention of excessive inhalation of the drug.

The present invention provides an aerosol generation system comprising: a controller for an inhalation device, the controller including a first power supply, a first connector, and a first processor configured to perform energization control of a heater which is used to heat an aerosol source, and a power supply device including a second power supply, a second connector which is connected to the first connector at the time of charging of the first power supply, and a second processor configured to perform control of power supply from the second power supply to the controller via the second connector, wherein a first voltage applied to a power supply terminal of the first processor and a second voltage applied to a power supply terminal of the second processor are different from each other.

A nasal delivery device for delivering substance to a nasal cavity of a subject, the delivery device comprising: a substance supply unit for supplying a dose of substance to be delivered to the nasal cavity of the subject, the substance supply unit including an inlet and an outlet; a nosepiece unit including a nosepiece for fitting to a nasal cavity of the subject and being in fluid communication with the outlet of the substance supply unit; and a mouthpiece unit including a mouthpiece in fluid communication with the inlet of the substance supply unit and through which the subject in use exhales such as to entrain substance from the container chamber and deliver the same through the nosepiece, and at least one temperature modifier for reducing a temperature of the exhaled air flow such as to reduce the absolute humidity thereof.

A nebulizer in accordance with the present invention comprises a nebulizing chamber including a vibratable micro micron mesh grid having a plurality of precision openings and passageways therethrough disposed in said chamber with a liquid pharmaceutical product contained in said nebulizing cartridge and passing through said openings in said vibratable micro micron mesh grid for producing particle sizes of said pharmaceutical product of about two (2) to five (5) microns; and an entrainment port for drawing air into and through the entrainment port into the nebulizing chamber and through the grid. A control circuit, a source of electrical energy in said circuit such as two 1.5 volt nickel cadmium batteries connected to said grid for producing vibration. A switch to turn said grid off and on and means for providing a first measured time period of about four seconds of time for taking a first breath of air through the entrainment port through the grid and through the thousands of passageways into the lungs and bloodstream of an individual. A second time period during which no vibration occurs.

A pulmonary delivery system includes an elongated body having an openable and closeable portion thereof for receiving an insertable and replaceable container such as a cartridge of pure medical product disposed in a saline solution. The medical product may be epinephrine, insulin or nicotine disposed in a saline solution. The system also incorporates a penetrating element that is disposed in the cylinder to pierce the cartridge and release the nicotine solution into the cylinder and into or on a micron mesh grid. A flow of air created by inhaling through a mouthpiece draws air into an individual's lungs from an entrainment port and onto a grid for atomizing a mist of micron droplets through the grid. It is recognized that the air from the entrainment port further dilutes the concentration of the medical product. The grid is connected to a source of electrical power to vibrate the mesh grid.

The invention relates to a method for manufacturing an inhaler article, the inhaler article comprising a body, a capsule cavity holding a capsule, a mouthpiece element and a deformable tubular element having an open distal end, the method comprising pre-treating the distal end of the deformable tubular element to obtain a pre-treated portion with reduced structural stability, and folding the pre-treated portion inwards by at least 90 degrees to at least partially close the distal end. The invention relates also to a device for manufacturing an inhaler article and to an inhaler article obtainable by the device.

A battery-operated foam inhalation device which comprises a cartridge (610) having a liquid for producing a foam and a foam outlet (654). Agitation means agitates the liquid to produce the foam, and the agitation means comprises an electric motor (762) and a battery (760) for energising the electric motor (762). A carrier (672) receives the cartridge (610) and has a carrier foam inlet (680) for fluid communication with the foam outlet (654) of the cartridge (610). A carrier foam outlet (682) dispenses the foam to a user.

A valved container assembly which has a container for containing a fluid, the container extending in an axial direction and having an open front end and a valve disposed in the container. The valved container assembly is configured so that forward axial movement of the valve relative to the container is inhibited. A plunger element is disposed axially rearward of the valve and is axially moveable in the container. The plunger element is configured to increase the pressure of a fluid in a first volume of the container upon forward axial movement relative to the valve. The valve includes a channel bypassing the permanent seal, the channel having a first opening in fluid communication with the atmosphere outside of the valved container assembly and a second opening selectively sealed from the first volume by a resilient seal.
