An aerosol preparation assembly includes an entrainment chamber defining an entrainment volume. The entrainment chamber includes a gas inlet port, an aerosol inlet port and an outlet port. The entrainment chamber is configured such that a velocity of a flow of a gas within the entrainment volume is less than a velocity of the flow of the gas within the gas inlet port. The entrainment chamber is configured such that at least a portion of inlet aerosol is entrained into the flow of the gas within the entrainment volume to produce an entrained aerosol flow at the outlet port. The particle selection chamber is configured to receive the entrained aerosol flow and produce an outlet aerosol flow. The particle selection chamber and nozzle are collectively configured such that a volumetric median diameter of the outlet aerosol flow is less than a volumetric median diameter of the inlet aerosol.

Device and method of use are described in which a housing is configured and coupled to an aerosol generator which delivers aerosol into an oxygen stream transporting both to a patient via a nasal cannula, in a way to minimize condensation at low liters per minute flow rate.

A liquid atomizing device includes a medical solution cup connected to an air pump, and an output cover installed onto the medical solution cup and including an atomizing socket formed in the outer cover, and the top of the atomizing socket cover has a linear opening and a drainage groove for increasing the flow of a medical solution. When the medical solution is guided to flow upwardly through the drainage and sprayed from a specially designed linear opening to the outside through the drainage groove due to a high speed airflow, the medical solution is collided with a barrier rod disposed above the linear opening to form an atomized medical solution, and the linear opening has the effect of atomizing the medical solution stably.

The invention relates to devices for aerosol generation comprising a container holding a liquid, an aerosol generator having a supply container holding the liquid, and an apparatus for conditioning the aerosol of the aerosol generator, said apparatus having a collection container for liquid and an outlet for the aerosol, in a series connection, wherein the aerosol generator is connected to a pressurized gas generator. The invention also relates to uses of such devices. Said devices and uses are characterized in particular by interruption-free operation. For this purpose, the collection container is connected to the aerosol generator via a first non-return valve in the passage direction and via a first jet pump, wherein the opening pressure of the first non-return valve is smaller than the pressure that can be achieved by the first jet pump. Furthermore, the container is connected to the aerosol generator via a second non-return valve in the passage direction and via a second jet pump, wherein the opening pressure of the second non-return valve is greater than the pressure difference between the supply container of the aerosol generator and the surroundings of the device for aerosol generation and smaller than the pressure that can be achieved by the second jet pump.

One aspect of the present invention relates to an inhaler which is capable of generating super fine particle which has a uniform particle size and has a core-shell structure in which the core comprises a first liquid substance to be sprayed and the shell comprises a second liquid substance to be sprayed. According to this aspect, the present invention can spray superfine particles of liquid medicine and the like with a uniform particle size, and can perform coating for sustained release and the like for the superfine particles.

The present disclosure provides an atomization apparatus, which relates to the field of aromatherapy equipment. The atomization apparatus may include a body having an internal cavity, a reservoir chamber disposed in the internal cavity, a spacer disposed above the reservoir chamber, and an oil cup. The spacer and a top wall of the internal cavity may form an atomized gas passage. The atomized gas passage may be communicated with a nozzle of the body. The oil cup may be disposed inside the reservoir chamber and located outside a projection of the spacer onto the reservoir chamber. A bottom of the oil cup may be communicated with the reservoir chamber.

An aerosol inhalation spacer for use with a metered-dose inhaler canister is disclosed. The spacer includes a transparent chamber housing having a body with an input end and an output end and defining an interior space. A mouthpiece is connected to the output end of the chamber housing. An inhaler adapter is connected to the input end of the chamber housing. A valve member is disposed between the mouthpiece and the output end of the chamber housing, the valve member includes a one-way inhalation valve and a one-way exhalation valve. A flow indicator is connected to the inhaler adapter and extends into the interior space of the chamber housing for indicating an inhalation flow rate to the user.

The invention relates to a powder inhaler and to a powder inhaler set that contains the powder inhaler. The powder inhaler comprises two half-shells (3, 4), which are connected to each other by means of at least one film hinge and are formed as a single piece. In a joined arrangement, the two half-shells (3, 4) enclose an air inlet region, a powder deposition region and powder release region, and an outlet region, through which regions a fluid path extends, wherein at least one of the half-shells (3, 4) has at least one air inlet opening (8) in the air inlet region. Furthermore, one of the half-shells (3, 4) has at least one powder-accommodating recess (9) in the powder deposition region and powder release region, while the outlet region has at least one deagglomeration structure (17, 17) and an outlet for aerosol, which outlet is formed by the half-shells (3, 4).

A droplet delivery device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The droplet delivery device includes a housing, a reservoir, and ejector mechanism, and at least one differential pressure sensor. The droplet delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The droplet delivery device is then actuated to generate a stream of droplets having an average ejected droplet diameter within the respirable size range, e.g, less than about 5 m, so as to target the pulmonary system of the user.

A smoking system includes a capillary wick for holding liquid, at least one air inlet, at least one air outlet and a chamber between the air inlet and air outlet. The air inlet, the air outlet and the chamber are arranged so as to define an air flow route from the air inlet to the air outlet via the capillary wick so as to convey aerosol formed from the liquid to the air outlet. The smoking system further includes at least one guide for channeling the air flow in the air flow route, so as to control particle size in the aerosol. The smoking system optionally includes at least one heater for heating the liquid in at least a portion of the capillary wick to form the aerosol.
