| Abstract Scope |
Life-saving interventions utilize endotracheal intubation to secure a patient's airway, but the performance of the clinical standard of care endotracheal tube (ETT) is inadequate. Patients undergoing prolonged intubations frequently experience health complications such as tracheal stenosis, pneumonia, and necrosis of the tracheal tissue as current ETTs are not designed for extended use. In this talk, we will present an improved ETT design that seeks to overcome these limitations by utilizing unique geometries which enable a novel expanding cylinder. The mechanism provides a better distribution of the contact forces between the ETT and the trachea, which should enhance patient tolerability. In-vivo tests show that at full expansion, the new ETT exerts pressures in the trachea well within the recommended standard of care. Also, preliminary manikin tests demonstrated that the new ETT can deliver similar performance in terms of air pressure and air volume when compared with the current gold standard ETT. |
