Abstract
Abstract An endotracheal tube splitter and a method for removing an endotracheal tube are disclosed. The endotracheal tube splitter includes a handle portion, a cutting edge for cutting the endotracheal tube as it is withdrawn from a patient, and a support member for preventing the cutting edge from turning to either side and for maintaining the cutting edge at least a minimum desired distance from the face of the patient. The endotracheal tube splitter allows the more rapid replacement of the endotracheal tube, and allows a bronchoscope to be used as the guide for placing the tube.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
188 words
An endotracheal tube splitter for removing endotracheal tubes from an inhibating position within a patient wherein a first end of the endotracheal tube is disposed in the trachea and a second end is adpated to be disposed outside the patient, the splitter comprising: handle means configured for gripping by a human hand; cutting means connected to the handle means for cutting through the endotracheal tube from the second end to the first end as the tube is withdrawn from the patient, stabilizing support means coupled to the handle means for inhibiting rotation of the cutting means so as to facilitate cutting of the endotracheal tube in a generally straight line continuously between the second and first ends, and for holding the cutting means at least a predetermined minimum distance from the patient, wherein the cutting means comprises a cutting blade and a forwardmost end defining a guide means for insertion into the endotracheal tube and for guiding the cutting blade along the endotracheal tube, and wherein the guide means comprises a first side for sliding along the endotracheal tube and a second, forwardmost side having a concave curvature.
Claim 2
Dependent Claim
188 words
An endotracheal tube splitter for removing endotracheal tubes from an inhibating position within a patient wherein a first end of the endotracheal tube is disposed in the trachea and a second end is adpated to be disposed outside the patient, the splitter comprising: handle means configured for gripping by a human hand; cutting means connected to the handle means for cutting through the endotracheal tube from the second end to the first end as the tube is withdrawn from the patient, stabilizing support means coupled to the handle means for inhibiting rotation of the cutting means so as to facilitate cutting of the endotracheal tube in a generally straight line continuously between the second and first ends, and for holding the cutting means at least a predetermined minimum distance from the patient, wherein the cutting means comprises a cutting blade and a forwardmost end defining a guide means for insertion into the endotracheal tube and for guiding the cutting blade along the endotracheal tube, and wherein the guide means comprises a first side for sliding along the endotracheal tube and a second, forwardmost side having a concave curvature.
Claim 3
Dependent Claim
56 words
The endotracheal tube splitter of claim 1, wherein the endotracheal tube splitter is configured for cutting an endotracheal tube from about a bronchoscope having a convex outer surface disposed within the endotracheal tube, and wherein the second, forwardmost side has a radius of curvature of at least as large as the outer surface of the bronchoscope.
Claim 4
Dependent Claim
188 words
An endotracheal tube splitter for removing endotracheal tubes from an inhibating position within a patient wherein a first end of the endotracheal tube is disposed in the trachea and a second end is adpated to be disposed outside the patient, the splitter comprising: handle means configured for gripping by a human hand; cutting means connected to the handle means for cutting through the endotracheal tube from the second end to the first end as the tube is withdrawn from the patient, stabilizing support means coupled to the handle means for inhibiting rotation of the cutting means so as to facilitate cutting of the endotracheal tube in a generally straight line continuously between the second and first ends, and for holding the cutting means at least a predetermined minimum distance from the patient, wherein the stabilizing support means comprises a support member extending generally downwardly from the handle means for resting on the patient's face; and wherein the support member has an upper portion for attachment to the handle means and a broad base portion extending transverse with respect to the handle means for resting on the patient's face.
Claim 5
Dependent Claim
188 words
An endotracheal tube splitter for removing endotracheal tubes from an inhibating position within a patient wherein a first end of the endotracheal tube is disposed in the trachea and a second end is adpated to be disposed outside the patient, the splitter comprising: handle means configured for gripping by a human hand; cutting means connected to the handle means for cutting through the endotracheal tube from the second end to the first end as the tube is withdrawn from the patient, stabilizing support means coupled to the handle means for inhibiting rotation of the cutting means so as to facilitate cutting of the endotracheal tube in a generally straight line continuously between the second and first ends, and for holding the cutting means at least a predetermined minimum distance from the patient, wherein the stabilizing support means comprises a support member extending generally downwardly from the handle means for resting on the patient's face; and wherein the support member has an upper portion for attachment to the handle means and a broad base portion extending transverse with respect to the handle means for resting on the patient's face.
Claim 6
Dependent Claim
37 words
The endotracheal tube splitter of claim 3, wherein the cutting means further comprises a pair of lateral sidewalls forming a wedge above the cutting blade for deflecting cut sides of the endotracheal tube away from one another.
Claim 7
Dependent Claim
15 words
The endotracheal tube splitter of claim 4, wherein the wedge comprises generally concave curved sidewalls.
Claim 8
Dependent Claim
29 words
The endotracheal tube splitter of claim 3, wherein the stabilizing support means extends downwardly so as to hold the cutting means at least one inch from the patient's face.
Claim 9
Dependent Claim
35 words
The endotracheal tube splitter of claim 3, wherein the base portion comprises a base layer disposed at an end of the base portion opposite the upper portion, the base layer comprising a slip resistant surface.
Claim 10
Dependent Claim
35 words
The endotracheal tube splitter of claim 3, wherein the base portion comprises a base layer disposed at an end of the base portion opposite the upper portion, the base layer comprising a force absorbing material.
Claim 11
Dependent Claim
41 words
The endotracheal tube splitter of claim 3, further comprising sight alignment means positioned generally parallel with a cutting plane of the blade for assisting in proper alignment of the cutting means and minimizing rotation of the blade to either lateral side.
