Model larynx for human use - one piece construction true-to-life in size, colour and texture

摘要

Life size larynx model is made of one body with a mouth opening and a pipe part, leading into the body which represents the larynx throat passage in a suitably developed form. The internal part is made of opaque material, it has a tongue (20) a soft palet and uvula (26) and portrays in colour and softness the real thing. In the larynx area there is an opening (19) and picture transmitting channel (28) into which photo slides (29) are inserted, so that when illuminated from source (30), via reflector (33), a picture is visible through the mouth and the larynx passage. Alternatively (29) can be replaced by a filter and in place of (30) a projector is provided, in order to throw a picture onto the transparent filter.
