Device for insertion of endotracheal tube
View Patent ↗The present invention provides an apparatus for advancing an endotracheal tube through and along the length a patient's larynx with a laryngeal mask airway in place and without interrupting ventilation.
1. A system, comprising:
an endotracheal tube; and
a push rod for inserting the endotracheal tube into a patient where the patient has a laryngeal mask airway in place, wherein the push rod comprises two separate components comprising:
a tubular body portion for pushing the endotracheal tube into the patient through the laryngeal mask airway with uninterrupted ventilation, and
a tapered end portion, wherein the tapered end portion is stepped to a smaller outer diameter towards the endotracheal tube for direct connection to the endotracheal tube.
2. The system of claim 1 , wherein a larger end of the tapered end portion ranges from about 2.0 mm to about 9.0 mm in diameter.
3. The system of claim 2 , wherein the larger end of the tapered end portion ranges from about 4.0 mm to about 6.0 mm in diameter.
4. The system of claim 1 , wherein a smaller end of the tapered end portion ranges from about 1.0 mm to about 8.0 mm in diameter.
5. The system of claim 4 , wherein the smaller end of the tapered end portion ranges from about 2.0 mm to about 5.0 mm in diameter.
6. The system of claim 1 , wherein the push rod comprises a biocompatible material.
7. The system of claim 6 , wherein the biocompatible material is medical grade material.
8. The system of claim 6 , wherein the biocompatible material is a plastic, a polymer or metal.
9. The system of claim 6 , wherein the biocompatible material is medical grade polyvinyl chloride.
10. The system of claim 1 , wherein the push rod is semi-flexible.
11. The system of claim 1 , wherein the push rod is substantially rigid.
12. The system of claim 1 , wherein the tapered end portion is bidirectionally tapered.
