Inhalation therapy device with a nozzle nebuliser

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.

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.
