Abstract

The utility model relates to a light aiming intubator, used for the trachea intubating process during general anesthesia and revival after first aid. The traditional trachea intubation is divided into the intubation under direct vision and blind intubation; as for the intubation under direct vision, during the glottis appearing process, especially when the trachea is difficult to be intubated, the lip and tongue easily gets hurt, even the tooth can loose or fall off; if the sufferer is revealed with a corpulent body, a short neck, a small mandible or a high larynx, the intubating process is difficult to be performed because of the difficulty of appearing the glottis; the blind intubation utilizes the breathing airflow sound to guide the intubating process and is lack of vision, so the intubation process is difficult, time consuming and more injuries. The light aiming intubator comprises a power supply box, a switch, a polyethylene hose, in which two copper insulated fine wires are arranged, an adapting tube joggled fixer, and a high-brightness light emitting diode, and is completed with the tracheal catheter. The light with low heat but high brightness can be emitted after switching on the power supply; when the opening at the distal end of the tracheal catheter approaches the glottis, the light visible at the cricothyroid membrane in front of the neck of the patient emits towards the trachea for guiding the intubating process. The utility model has the advantages of shortening the intubating time, increasing the intubating success rate and decreasing the injuries.
