Abstract:The ArtPlac-project aims to build a combined lung and kidney support system that can be connected through the umbilical cord using a specialized, to be developed, cannula. The aim of this master’s thesis is to identify realistic materials and production processes that can be used to develop vasculature models for use in a realistic neonatal cannulation-simulator. Material choices for use in a cannulation-simulator were evaluated. For creating veins, four silicones and two 3D-printable materials were considered. Tensile-test results for Young’s modulus, tensile strength and breaking strain were compared to values found in literature for human umbilical veins. Veins were produced from HT33, Vascuflex, and Superflex, for further evaluation. Neonatologists performed simulated cannulation procedure on simulators and provided feedback on the materials through a survey. According to the survey, more flexible materials were preferred, especially for the Wharton’s jelly. Tensile strength and breaking strain did not seem to affect the simulator experience in terms of puncturing and tearing. Movement of the vein within the body was found to be imperceptible by participants. 3D-printing anatomically correct vasculature models using Superflex was found to be performing best in terms of haptic realism. To mimic Wharton’s-jelly, a more compliant material should be identified.
