An intubation device for insertion into a patient's trachea is provided. The intubation device includes a catheter and an endotracheal tube coaxially positioned over the catheter, where an interior surface of the endotracheal tube and an exterior surface of the catheter define an interstitial space. The device also includes a hub that has a gas supply port configured to connect the body of the hub with a gas supply source, a first port in a proximal end and a second port in a distal end. Each of the first port and the second port is configured to receive the catheter and the hub also includes a connector configured to connect to the endotracheal tube such that the interstitial space is in fluid communication with the body and the gas supply port.
