Embodiment Construction

[0029] Referring to the drawings, a humidifier for humidifying an aerosol will be explained in more detail.

[0030] The humidifier comprises a first water compartment 100 containing water flowing through an intermediate chamber 200 for humidifying the aerosol. The humidifier also contains a second water compartment 300 which also contains water for humidifying the aerosol. The intermediate chamber is sandwiched between the first water compartment 100 and the second water compartment 300 . Between the first water compartment 100 and the intermediate chamber 200 there is provided a first layer 10 which is water vapor permeable but liquid water impermeable. Between the chamber 200 and the second water compartment 300 a second layer 20 is provided which is water vapor permeable but liquid water impermeable.

[0031] The aerosol to be humidified enters the intermediate chamber through the aerosol inlet 210 . Channel 230 is constructed in the intermediate chamber, especially as ...

Abstract

The present invention relates to a humidifier configured to humidify an aerosol, said humidifier comprising: a first water compartment (100) containing water for humidifying said aerosol; a second water compartment (300) containing water for humidifying said aerosol; an intermediate chamber (200) located between said first water compartment and said second water compartment (100, 300), The intermediate chamber (200) comprises an aerosol inlet (210) and an aerosol outlet (220), and provides a first boundary surface of a channel (230) through which the aerosol to be humidified passes; the first layer (10) , which is permeable to water vapor and impermeable to liquid water, located between said first water compartment (100) and said intermediate chamber (200), wherein a section of said first layer provides said A second boundary surface of the channel; a second layer (20), permeable to water vapor and impermeable to liquid water, located between said second water compartment (300) and said intermediate chamber (200) , wherein the section of the second layer provides a third boundary surface of the channel (230) opposite the second boundary surface.

Description

technical field [0001] The present invention relates to humidifiers configured to humidify aerosols. Background technique [0002] In a device for aerosolizing dry aerosolizable materials, the aerosolizable material (e.g. a powdered pharmaceutical substance) is acted upon in a specially provided chamber with a compressed gas or a carrier gas , and by entraining the particles into the gas flow, the material is transformed within this chamber into a state known as an aerosol. The particles of the dry material are preferably present in homogeneous and finely dispersed form throughout the volume of the compressed gas. [0003] In the context of pharmaceuticals, such devices are used for the inhalational administration of pharmaceutical formulations to normally breathing patients as well as mechanically ventilated patients and patients requiring respiratory assistance, among others. In the first case, typical examples of such devices are hand-held dry powder inhalers (DPI) and ...
