Endotracheal tube insertion
An intubation system includes: a base configured to be secured relative to a subject; a guide movably coupled to the base to allow the guide to move relative to the base; and a connector configured to be connected to a distal end of the guide and to detachably connect to an endotracheal tube such that as the guide is moved relative to the base toward the subject, the endotracheal tube is inserted into the subject.
1. An intubation system comprising:
a base configured to be secured relative to a subject;
a guide movably coupled to the base to allow the guide to move relative to the base;
a securement apparatus connected to and extending away from the base for coupling the guide to the base; and
a connector configured to be connected to a distal end of the guide and to detachably connect to a first endotracheal tube such that as the guide is moved relative to the base toward the subject, the first endotracheal tube is inserted into the subject;
wherein the guide is sized and shaped to have a second endotracheal tube removed from the subject and slid over the guide while the securement apparatus secures the first endotracheal tube in the subject such that control of an airway of the subject is maintained while exchanging the first endotracheal tube for the second endotracheal tube in the airway of the subject.
2. The system of claim 1 , wherein the guide comprises a rod and a guide lock mechanism configured to lock the rod in place relative to the base.
3. The system of claim 1 , wherein the guide comprises a depth gauge.
4. The system of claim 3 , wherein the depth gauge is indicative of a position of the endotracheal tube relative to the base.
5. The system of claim 4 , wherein the guide comprises a depth lock mechanism configured to inhibit movement of the guide past a location corresponding to the depth lock mechanism to inhibit insertion of the endotracheal tube beyond a threshold depth in the subject.
6. The system of claim 5 , wherein the base comprises a mouthpiece having a shape approximating a shape of a face of the subject adjacent a mouth of the subject.
7. The system of claim 1 , further comprising the first endotracheal tube, wherein the first endotracheal tube is an expandable endotracheal tube configured such that at least a portion of a length of the first endotracheal tube has an expandable cross-section.
8. An intubation system comprising:
means for guiding an endotracheal tube into an existing endotracheal device in a subject and for guiding the existing endotracheal device while the existing endotracheal device is extracted from the subject;
means for holding the endotracheal tube in place relative to the subject while the existing endotracheal device is extracted from the subject such that control of an airway of the subject is maintained while exchanging the existing endotracheal device for the endotracheal tube in the airway of the subject; and
means for releasing the endotracheal tube.
9. The system of claim 8 , further comprising means for indicating a depth of the endotracheal tube in the subject.
10. The system of claim 8 , further comprising means for inhibiting insertion of the endotracheal tube beyond a desired depth in the subject.
11. The system of claim 8 , wherein the means for guiding comprise means for movably connecting the means for guiding relative to the subject.
12. A method of intubating a subject, the method comprising:
movably connecting a guide mechanism relative to the subject;
attaching the guide mechanism to an endotracheal tube;
inserting the endotracheal tube into an existing endotracheal device disposed in the subject until a desired insertion depth is reached as indicated by the guide mechanism and while maintaining control of an airway of the subject; and
extracting the existing endotracheal device from the subject by sliding the existing endotracheal device over the guide mechanism while maintaining control of the airway of the subject by leaving the endotracheal tube in the subject.
13. The method of claim 12 , further comprising setting the desired insertion depth on the guide mechanism before inserting the endotracheal tube into the subject.
14. The method of claim 12 , further comprising detaching the guide mechanism from the endotracheal tube after extracting the existing endotracheal device from the subject.
15. The method of claim 12 , further comprising expanding a cross-sectional area of the endotracheal tube to seal the endotracheal tube against a wall of a trachea of the subject after extracting the existing endotracheal device from the subject.
16. The method of claim 12 , wherein attaching the guide mechanism to the endotracheal tube comprises attaching the guide mechanism to the endotracheal tube at a connection point of the endotracheal tube such that the connection point is fixed relative to a length of the guide mechanism.
