Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
179 words
A tracheotomy tube having a cuffed end with an aperture in the wall of the tube intermediate its ends and means slidably cooperable with the wall of the tube to selectively open and close the aperture therein, said means being such as to provide a minimum change and obstruction in the bore of the tube, said means comprising a removable insert slidable in the bore of the tube, the insert having substantially the same curvature as the tube and having a sealing surface adapted to cooperate with the aperture in the wall of the tube, and the removable insert comprising a thin wall tubular body having three axially extending cut-out portions such that in any plane normal to its length the insert is of part-annular section, a first and second of said cut-out portions being separated by a bridge piece formed in a lower portion of the insert remote from the sealing surface, and the third cut-out portion being formed in the upper portion of the insert and overlapping the adjacent ends of the first and second cut-out portions.
Claim 2
Dependent Claim
179 words
A tracheotomy tube having a cuffed end with an aperture in the wall of the tube intermediate its ends and means slidably cooperable with the wall of the tube to selectively open and close the aperture therein, said means being such as to provide a minimum change and obstruction in the bore of the tube, said means comprising a removable insert slidable in the bore of the tube, the insert having substantially the same curvature as the tube and having a sealing surface adapted to cooperate with the aperture in the wall of the tube, and the removable insert comprising a thin wall tubular body having three axially extending cut-out portions such that in any plane normal to its length the insert is of part-annular section, a first and second of said cut-out portions being separated by a bridge piece formed in a lower portion of the insert remote from the sealing surface, and the third cut-out portion being formed in the upper portion of the insert and overlapping the adjacent ends of the first and second cut-out portions.
Claim 3
Dependent Claim
32 words
A tracheotomy tube according to claim 1 in which the sealing surface is profiled and contoured to form a raised portion which fits into the aperture in the wall of the tube.
Claim 4
Dependent Claim
122 words
In combination, a tracheotomy tube and removable insert means, the tube having an inflatable cuffed end for insertion in a patient's trachea, an opposite end for releasable connection to a ventilator and an aperture in the wall of the tube intermediate its ends, the removable insert means cooperating with the tube to engage and seal the aperture in an airtight fit, said insert means being such as to provide a minimum change and obstruction in the bore of the tube whereby, in use, with the cuff inflated and said insert means in sealing engagement with the aperture a patient can be ventilated by the ventilator and upon removal of the insert means the patient can breathe spontaneously through the nose and mouth.
Claim 5
Dependent Claim
122 words
In combination, a tracheotomy tube and removable insert means, the tube having an inflatable cuffed end for insertion in a patient's trachea, an opposite end for releasable connection to a ventilator and an aperture in the wall of the tube intermediate its ends, the removable insert means cooperating with the tube to engage and seal the aperture in an airtight fit, said insert means being such as to provide a minimum change and obstruction in the bore of the tube whereby, in use, with the cuff inflated and said insert means in sealing engagement with the aperture a patient can be ventilated by the ventilator and upon removal of the insert means the patient can breathe spontaneously through the nose and mouth.
Claim 6
Dependent Claim
50 words
A combination according to claim 3, in which the insert means is formed with a sealing surface which is profiled and contoured to sealingly engage the aperture in the tube, the insert means being cooperable with the tube to continually urge the sealing surface into sealing engagement with the aperture.
Claim 7
Dependent Claim
38 words
A combination according to claim 4, including cooperable keying means on the tube and the insert means to prevent relative rotational movement therebetween when the insert means is located in the tube in sealing engagement with the aperture.
Claim 8
Dependent Claim
94 words
A combination according to claim 3, in which the insert means comprises a thin wall tubular body having three axially extending cut-out portions such that in any plane normal to its length the insert means is of part-annular section, a first and second of said cut-out portions being separated by a bridge piece formed in a lower portion of the insert means remote from the sealing surface, and the third cut-out portion being formed in the upper portion of the insert means and overlapping the adjacent ends of the first and second cut-out portions.
Claim 9
Dependent Claim
72 words
A combination according to claim 3, in which the insert means comprises an elongated insert member which is slidably positionable within the interior bore of the tube so that the insert member slidably engages only the upper internal wall of the interior bore, said insert member having a sealing portion which is profiled and contoured to sealingly engage the aperture in the tube when the insert member is positioned within the tube.
Claim 10
Dependent Claim
36 words
A combination according to claim 7, wherein the insert member continuously urges the sealing portion into sealing engagement with the aperture so as to close same when the insert member is properly positioned within the tube.
Claim 11
Dependent Claim
29 words
A combination according to claim 8, wherein the sealing portion of the insert member forms a raised or bulbous portion which fits into the aperture for sealingly closing same.
