Project Title
Radially Collapsible Endotracheal Tube
Design Challenge
Of the 51.7 million intubations that occur annually, 10% encounter complications, resulting in 5.3 million complications. These complications can mainly be attributed to poor visibility due to the large diameters of the endotracheal tubes (ETTs) necessary to maintain sufficient airflow to the lungs. Impaired visibility increases the chance that the clinician will hit the surrounding tissue, causing injuries that could ultimately become major medical and financial burdens to the patient. Our novel device inserts at a small diameter to ease intubation and then radially expands to enhance airflow, striking a compromise that current ETTs lack by only accommodating a single diameter. Our collapsible design decreases diameter by half to increase visibility around the ETT by 25%. This improved visibility will ease the process of intubation for clinicians, therefore improving patient outcomes.
