Abstract: The present invention relates to a membrane unit for generating an aerosol in an aerosol therapy device, the membrane unit comprising a membrane (1) having an area (6) comprising a plurality of through-holes for nebulizing a fluid and a flange (7) circumferentially surrounding the area (6), and a substrate (2) having an opening (8) wherein the flange (7) of the membrane (1) is welded to the substrate (2) so that the area (6) is located in the opening (8) wherein the weld (5) comprises at least three discontinuous welds (5c) arranged at a distance from each other a long a circumference of the opening (8) and a first annular weld (5b) circumferentially surrounding the opening (8).

Abstract: A measuring probe head having a housing, which defines a receiving space and at least one coolant fluid supply channel fluidically connected thereto, and at least one sensor which is received, or is capable of being received, in the receiving space, wherein at least one partial region of the housing enclosing the receiving space has a porosity which defines a plurality of coolant fluid passage openings.

Abstract: A membrane nebulizer for producing aerosol in an aerosol therapy device includes a membrane having several through-holes for nebulizing a fluid; and a laminar carrier having an opening, the membrane being arranged in the opening and fastened to the carrier in such a way that the nebulizing occurs on a first side of the carrier and the fluid is present at the membrane on the opposite second side of the carrier, wherein the membrane is welded to the carrier by means of a resistance welding method.

Abstract: The invention relates to a method for operating an aerosol delivery device (10), comprising the steps of generating a predetermined amount of an aerosol in the device (10) and inducing a transport flow in the device (10) for transporting at least a portion of the predetermined amount of the aerosol outside the device (10). During the aerosol generating step, the transport flow is first induced, then stopped after a predetermined first period of time and then induced again after a predetermined second period of time.
