This is a model for this project on Hackaday
Babies in critical care (NICU) sometimes need nasal tubes for air etc. Nasal CPAP cannula.
But they come in only a couple of sizes for tiny babies. A baby's nasal passages are very soft and can get easily damaged and the baby uncomfortable, if the fit is not right.
This project by Ben Hartmann is to create 3D printed cannula individually fitted to a specific baby. Quickly and easily in the NICU.
This model is customisable and produces a mold which can be injected with a platinum cure silicone (baby safe) to make a cannula for a specific baby.
The 3 core measurments are the individual nare diameters (nasal openings) and the distance between them (septum distance).
These three measuremnts are the critical ones. The many other parameters are to adjust the size of the cannula and the diameter of the tubes that connect to either end.
Curvature of the entire device has not been implemenetd - more work is needed to make this better. Consider helping if you'd like (join the hackaday project).
