Abstract: This disclosure discloses a tracheal intubation device designed to improve safety during intubation attempts. The device allows for the delivery of medical gas (such as oxygen) flow through the endotracheal tube itself during intubation attempts. This moves the source of apneic oxygen lower in the patient's airway to bypass anatomy that otherwise can obstruct medical gas flow. The device can also switch on-demand to generating suction through the endotracheal tube to clear away fluids that block the intubator's view and that block medical gas flow. There are currently no devices that can deliver both medical gas and on-demand suction using the endotracheal tube as the flow conduit during the process of intubation. The present device accomplishes these tasks while incorporating non-obvious elements to optimize its use and efficacy.
