Abstract

Systems and methods for using a guidewire to intubate a standard endotracheal tube in a patient. An insertion mechanism is used to enable delivery of a guidewire to the tracheal cavity of a patient. The guidewire is then threaded up the tracheal cavity, through the glottic opening and up either the oropharyngeal airway, so as to extend out of the patient'"'"'s mouth, or up the nasopharyngeal airway, so as to extend out of the patient'"'"'s a nostril. A typical endotracheal tube, having a channel that extends from a proximal end to a distal end of the tube, is coupled to the guidewire and is positioned into the tracheal cavity of the patient by using the guidewire to withdraw the tube down the airway and into the trachea. The endotracheal tube is decoupled from the guidewire, and the guidewire is removed from the patient, leaving the endotracheal tube properly intubated in the patient.

Claims

1. An intubation system configured to facilitate the positioning of an endotracheal tube in a patient, the system comprising:

a guidewire; and

a coupling mechanism to selectively couple the guidewire to a standard endotracheal tube, wherein the coupling mechanism comprises at least one of;

(i) a clamp; and

(ii) an inflatable bulb.

2. An intubation system as recited in claim 1, wherein the inflatable bulb is coupled to the guidewire and to a pump, which selectively inflates the bulb to couple the guidewire to a portion of an inside wall of the endotracheal tube.

3. An intubation system as recited in claim 2, wherein the inflated bulb provides a taper on a proximal end of the tube.

4. An intubation system as recited in claim 2, wherein the inflated bulb includes a configuration that allows air to pass through the channel while the bulb is inflated.

5. An intubation system as recited in claim 1, wherein at least a portion of the guidewire includes a coating thereon, wherein the coating includes a lubricating material.

6. An intubation system as recited in claim 1, further comprising an insertion mechanism to enable delivery of a portion of the guidewire into a tracheal cavity of the patient, wherein the insertion mechanism comprises at least one of:

(i) a needle; and

(ii) a sheath.

7. An intubation system as recited in claim 6, wherein the insertion mechanism is configured to receive the guidewire at an insertion channel that allows the guidewire to selectively pass therethrough.

8. An endotracheal intubation kit comprising:

a guidewire; and

a coupling mechanism configured to selectively couple the guidewire to a standard endotracheal tube for the intubation of the endotracheal tube into a patient, wherein the coupling mechanism comprises at least one of;

(i) a clamp; and

(ii) an inflatable bulb.

9. An endotracheal intubation kit as recited in claim 8, further comprising an insertion mechanism configured to facilitate insertion of the guidewire into the patient, wherein the insertion mechanism includes an insertion channel that is configured to receive the guidewire.

10. An endotracheal intubation kit as recited in claim 9, wherein the insertion mechanism comprises a sheath that is configured to be inserted into the patient.

11. An endotracheal intubation kit as recited in claim 9, wherein the inflatable bulb is coupled to the guidewire and is configured to pass through the insertion channel to enable delivery of the guidewire to a tracheal cavity of a patient when the bulb is deflated, and wherein the bulb is configured to couple the guidewire to at least a portion of the endotracheal tube when the bulb is inflated.

12. An endotracheal intubation kit as recited in claim 10, further comprising a pump to selectively inflate the bulb.

13. An endotracheal intubation kit as recited in claim 10, further comprising the endotracheal tube having a channel that extends from a proximal end of the tube to a distal end of the tube, and a hub that is selectively coupled to the distal end of the tube.

14. An endotracheal intubation kit as recited in claim 8, wherein the guidewire includes a coating on at least a portion thereof.

15. A method for performing endotracheal intubation, the method comprising the steps for:

threading a guidewire from a portion of a tracheal cavity of a patient through an airway of the patient;

coupling the guidewire to a standard endotracheal tube;

using the guidewire to intubate the standard endotracheal tube into the patient; and

removing the guidewire from the patient.

16. A method as recited in claim 15, wherein the step for using comprises the step for withdrawing the guidewire down the airway to the tracheal cavity to position a distal end of the tube in the tracheal cavity.

17. A method as recited in claim 16, further comprising the step for decoupling the guidewire from the tube.

18. A method as recited in claim 17, wherein the step for coupling comprises at least one of the steps for:

(i) using a clamp to couple the guidewire to the tube; and

(ii) inflating a bulb coupled to the guidewire to couple the guidewire to the tube.

19. A method as recited in claim 15, further comprising the step for using an insertion mechanism to deliver the guidewire to the tracheal cavity.

20. A method as recited in claim 19, wherein the step for using an insertion mechanism includes the steps for:

placing the insertion mechanism into the patient; and

threading at least a portion of the guidewire through an insertion channel of the insertion mechanism to deliver the guidewire to the portion of the tracheal cavity.
