1. A tracheal tube insertion facilitator having capability of ventilating a human or an animal, comprising:
a) an outer cylindrical member with a proximal end, a hollow body and a distal tip which is configured to bend forward;
wherein the outer cylindrical member near its distal tip houses one or more ventilation ports that is in fluid communication with an inner lumen of the outer cylindrical member allowing escape of ventilated gases into lungs;
a self-inflating dynamic cuff disposed on a portion of the outer cylindrical member, proximal to the ventilation ports, said self-inflating dynamic cuff including an inner surface being in fluid communication with the inner lumen of the outer cylindrical member through inflation ports and configured to mimic intraluminal pressures without any time lag or pressure gradient, thereby facilitating inflation of the self-inflating dynamic cuff during positive pressure ventilation (PPV) and jet ventilation;
b) a hollow metallic stylet with a proximal end, a hollow body and a distal end, the hollow metallic stylet being positioned in the inner lumen of the outer cylindrical member;
wherein the hollow metallic stylet is configured to support the outer cylindrical member and provide jet ventilation through an interior of the hollow metallic stylet;
wherein the body of the hollow metallic stylet houses one or more inflation apertures at a position enclosed by the self-inflating dynamic cuff; wherein the air from jet ventilation into the hollow metallic stylet, traverses through the inflation apertures to the inflation ports.
