The aerosol generator comprises a nozzle element, said nozzle consisting of at least a first part and a second part, said first part of the nozzle element being made of a more resilient material than said second part of the nozzle element, and said first part of the nozzle element being attached to said second part of the nozzle element. Owing to the resilient material, the nozzle can deform during cleaning and can return to the original shape without altering its initial geometry. ## Claims ### Claim 1 An inhalation therapy device comprising: a nebulising chamber, an aerosol generator, which is arranged to release an aerosol into the nebulising chamber with a medicament, and which comprises a nozzle element and at least one medicament channel extending between the nozzle element and an outer member, said nozzle element comprising at least a first part and a second part, said first part of the nozzle element comprising a resilient deformable material, and including a deformable tip having a nozzle outlet comprising a nozzle edge configured to deliver a reproducible droplet spectrum of said aerosol through the nozzle outlet; the nozzle outlet being in fluid communication with the at least one medicament channel; said first part of the nozzle element being attached to said second part of the nozzle element and tapering from the second part with the cross-section of the first part converging to the deformable nozzle tip, and wherein said outer member is removable to expose portions of the at least one medicament channel; and wherein the nozzle outlet comprises a reversible deformable material configured to widen in dependence on flow through said nozzle outlet so that a stable state is established between the flow and medicament sucked into the flow. ### Claim 2 (depends on 1) An inhalation therapy device according to claim 1, wherein the first part of the nozzle element has a cross-section which tapers further than that of the second part of said nozzle element. ### Claim 3 (depends on 1) An inhalation therapy device according to one claim 1, wherein the first part of the nozzle element is made of silicone rubber or a thermoplastic elastomer (TPE). ### Claim 4 (depends on 1) An inhalation therapy device according to claim 1, wherein the first part of the nozzle element and the second part of said nozzle element comprises a two-component structure having said first part of the nozzle element molded on said second part of the nozzle element. ### Claim 5 (depends on 1) An inhalation therapy device according to claim 1, wherein the nozzle has a third part containing the nozzle outlet. ### Claim 6 (depends on 5) An inhalation therapy device according to claim 5, wherein the third part of the nozzle element and the first part of the nozzle element comprise a two-component molded structure. ### Claim 7 (depends on 1) An inhalation therapy device according to claim 1, wherein a third part of the nozzle element has a cross-section which tapers further than that of the first part of the nozzle element. ### Claim 8 (depends on 1) An inhalation therapy device according to claim 1, wherein the first part of the nozzle element consists of a material resuming original geometry following deformation. ### Claim 9 (depends on 1) An inhalation therapy device according to claim 1, wherein the outer member includes a portion converging to an opening aligned with the nozzle outlet and in fluid communication with the nozzle outlet. ### Claim 10 (depends on 1) An inhalation therapy device according to claim 1, the nozzle edge being reversibly deformable. ### Claim 11 An inhalation therapy device comprising: a nebulising chamber; an aerosol generator, which is arranged to release an aerosol into the nebulising chamber with a medicament, and which comprises a nozzle element and at least one medicament channel extending between the nozzle element and an outer member; said nozzle element comprising at least a first part and a second part, said first part of the nozzle element comprising a resilient deformable material, and including a deformable tip having a nozzle outlet comprising a nozzle edge configured to deliver a reproducible droplet spectrum of said aerosol through the nozzle outlet; the nozzle outlet being in fluid communication with the at least one medicament channel; said first part of the nozzle element being attached to said second part of the nozzle element and tapering from the second part with the cross-section of the first part converging to the deformable nozzle tip; wherein said outer member is removable to expose portions of the at least one medicament channel, wherein the nozzle has a third part containing the nozzle outlet; wherein the third part of the nozzle element is made of a less resilient material than the first part of said nozzle element. ### Claim 12 An inhalation therapy device comprising: a nebulising chamber, and an aerosol generator comprising a nozzle element mounted to a member, the aerosol generator being arranged such that the nozzle element releases an aerosol into the nebulising chamber, said nozzle element comprising at least a first part, said first part of the nozzle element comprising a reversibly deformable resilient nozzle tip, the nozzle tip forming a nozzle outlet comprising a nozzle edge around the nozzle outlet, the nozzle edge configured to deliver a reproducible droplet spectrum of said aerosol; the reversibly deformable resilient nozzle tip converging from the member to which the nozzle element is mounted to the nozzle edge; wherein the nozzle outlet comprises a reversible deformable material configured to widen in dependence on flow through said nozzle outlet so that a stable state is established between the flow and medicament sucked into the flow. ### Claim 13 (depends on 12) An inhalation therapy device according to claim 12, wherein the first part of the nozzle element is made of silicone rubber or a thermoplastic elastomer (TPE). ### Claim 14 (depends on 12) An inhalation therapy device according to claim 12, wherein the first part of the nozzle element consists of a material resuming original geometry following deformation. ### Claim 15 (depends on 12) An inhalation therapy device according to claim 12, the nozzle edge being reversibly deformable. ### Claim 16 (depends on 12) An inhalation therapy device according to claim 12, wherein the nozzle element is molded to the member.
