Abstract
Abstract An improved drug administering respiration endotracheal system which permits simultaneous multiple injection of life-saving medication into the lungs of the patient without interruption of the flow of life supporting gasses. The system includes a connector with a linear axial passageway for gasses and two (2) separate medication injection ports adapted to receive a hypodermic needle and a medical syringe.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
264 words
A 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; 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 coupled to the gas supply, a gas discharge end coupled to the proximal end of the tube and a linear axial passageway therebetween, the connector having a self-sealing hypodermic needle port coupled with a first aperture in the connector and extending into the linear passageway, the hypodermic needle port being rigid and 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 connector further having a self-sealing syringe port coupled with a second aperture in the connector and extending into the linear passageway, the syringe port being rigid and 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 ports being located between the ends of the connector, and the main axial passageway adapted for atomizing and entermixing of the flow of life-saving drugs with the life-supporting gas.
Claim 2
Dependent Claim

A 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; 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 coupled to the gas supply, a gas discharge end coupled to the proximal end of the tube and a linear axial passageway therebetween, the connector having a self-sealing hypodermic needle port coupled with a first aperture in the connector and extending into the linear passageway, the hypodermic needle port being rigid and 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 connector further having a self-sealing syringe port coupled with a second aperture in the connector and extending into the linear passageway, the syringe port being rigid and 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 ports being located between the ends of the connector, and the main axial passageway adapted for atomizing and entermixing of the flow of life-saving drugs with the life-supporting gas.
Claim 3
Dependent Claim
28 words
The drug administering endotracheal respiration system as set forth in claim 1 wherein the ports have axes which are co-planar with respect to the axis of the connector.
Claim 4
Dependent Claim
