ABSTRACT:
An improved drug administering endotracheal respiration system for administering vital life-saving drugs into the lungs of a victim while maintaining the flow of life-supporting gas thereto via ventilation apparatus comprising in combination a gas supply; a tube for establishing gas flow exchange between the lungs of the victim and the gas supply, the tube having a proximal end and a distal end for insertion into the trachea of the victim; and a connector for coupling the proximal end of the tube to the gas supply, the connector being formed as a cylinder with a gas input end and a gas discharge end and a linear axial passageway therebetween, the connector having a hypodermic needle port adapted for receiving a hypodermic needle for injecting vital life-saving drugs in liquid form into the passageway and then into the distal end of the tube intermixed with the gas, the hypodermic needle port having a portion integrally formed with the connector and a portion separable therefrom, the connector further having a syringe port adapted for receiving a syringe for injecting vital life-saving drugs in liquid form into the passageway and then into the distal end of the tube intermixed with the gas, the syringe port having a portion integrally formed with the connector and a portion separable thereform, the main axial passageway adapted for atomizing and intermixing of the flow of life-saving drugs with the life-supporting gas.
