Abstract
|
|
|
Background and Objectives: Ventilation tube is a percutaneous prosthesis which is exposed to external stimuli. The duration of retention and complication rate of ventilation tube partly depends on which type of tube is used. The purpose of
this
study is to classify ventilation tubes according to biofunctional characteristics and to design new ventilation tubes experimentally using computer graphics. Materials and Method: Two hundred and forty seven ventilation tubes were
classified
according to shape, size and material. Experimental design of a ventilation tube was performed with various graphic modellings. Results: Grommet style was most common and most of flanges showed round type. Polymer has been a meterial of
choice in
making ventilation tubes. Length of the shaft ranged 1.5㎜-15㎜. Four kinds of models were created for designing a ventilation tube using computer graphics. Conclusion: Biofunctionality should be taken into account in designing ventilation
tubes.
