Transparent model of a portion of human airways to study aerosol transport and visualization of air circulation and process for producing thereof

摘要

Model (1) airway man for examining the transport of aerosol by means of optical measuring methods and visualization of the airflow in the model (1) comprising an internal cavity with an inlet opening (20) for receiving an aerosol, and with a plurality of outlet openings (25) for output aerosol, and further includes an internal cavity which is spatially branched and wall model (1) consist of transparent silicone material thickness of 0.5 to 1 mm, reinforced in the region of the inlet opening (20) to a thickness in the range of 2 to 3 mm. In the production model (1) data about the shape of the inner cavity airway man put into an apparatus for rapid production of components and this unit is making a core having an outer shape corresponding to said shaped inner cavity, whereupon the core covers a transparent silicone layer of thickness 0, 5 to 1 mm at the tips thickened to 2 to 3 mm, then the silicon layer is cured, whereupon a cut end part of the model (1) forming the inlet (20) and outlet openings (25) and the core is leached and / or crumble and removed from the model (1).
