Abstract

This paper presents a development of a current design the Endotracheal tube holding device. At present, the medical teams have faced a lot of problems when doing the endotracheal intubation. Misplacement of endotracheal tube into the esophagus and extubation due to patient’s movement are among the problems by surgeons during medical treatment. This is important as the successful management of the potential risk can reduce the number of patients who suffer a serious consequence of endtracheal tube therapy such as a potential risk to patient safety, with associated risks varying from minor complications to death. This paper presents a product design specification for endotracheal tube-holding device is translated from user’s requirements by employing Quality Functional Deployment (QFD). Several design concepts are generated by using CATIA software to be evaluated by endotracheal tube-holding device users for concept selection. Selection of design concept was done in two phases which are concept screening and concept scoring. For selecting the design concept for further development, a prototype of endotracheal tube was fabricated by using Fused Deposition Modelling (FDM).
