Abstract
Abstract An endotracheal intubation control device is disclosed which is used with a flexible tube that is tapered for insertion into the trachea of a patient. A stylet is provided having a length greater than the tubular member and of a dimension allowing passage through the member with first magnetic means attached to one end of the stylet. A second magnetic means is provided for external placement over the tracheal orifice of a patient. The stylet is flexible and is inserted into the throat of the patient and acts as a guide for subsequent insertion of the endotracheal tube over the stylet.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
An endotracheal intubation assembly comprising a flexible intubating guide stylet; first magnetic means attached to one end of said stylet and movable therewith; an open ended flexible endotracheal tube having a lumen of a dimension substantially greater than the cross-sectional dimension of said stylet and said first magnetic means whereby said tube is freely movable over said stylet and said magnetic means, thereby permitting free flow of breathable gas along said lumen; and second magnetic means externally placeable over the tracheal orifice of a patient; whereby said one end of said stylet is inserted into the throat of said patient, with said first magnetic means being directed onto the trachea by said second magnetic means which is placed adjacent the external surface of said tracheal orifice area, and said endotracheal tube is threaded over said stylet and guided into the trachea by said stylet.
Claim 2
Dependent Claim
144 words
An endotracheal intubation assembly comprising a flexible intubating guide stylet; first magnetic means attached to one end of said stylet and movable therewith; an open ended flexible endotracheal tube having a lumen of a dimension substantially greater than the cross-sectional dimension of said stylet and said first magnetic means whereby said tube is freely movable over said stylet and said magnetic means, thereby permitting free flow of breathable gas along said lumen; and second magnetic means externally placeable over the tracheal orifice of a patient; whereby said one end of said stylet is inserted into the throat of said patient, with said first magnetic means being directed onto the trachea by said second magnetic means which is placed adjacent the external surface of said tracheal orifice area, and said endotracheal tube is threaded over said stylet and guided into the trachea by said stylet.
Claim 3
Dependent Claim
23 words
The device of claim 1 wherein said stylet comprises a spring coil member having said first magnetic means secured to one end thereof.
Claim 4
Dependent Claim
19 words
The device of claim 1 further comprising a spring bellows connected between said stylet and said first magnetic means.
Claim 5
Dependent Claim
21 words
The device of claim 2 further comprising a spring bellows connected between said spring coil member and said first magnetic means.
Claim 6
Dependent Claim
14 words
The device of claim 1 wherein said stylet comprises a tubular plastic flexible member.
Claim 7
Dependent Claim
29 words
The device of claim 1 wherein said magnetic means comprises a plurality of magnets having their poles arranged for adjacent magnetic attraction whereby articulation may occur between adjacent magnets.
Claim 8
Dependent Claim
23 words
The device of claim 1 further comprising means providing a substantially smooth arcuate termination at the distal end of said first magnetic means.
