Abstract
Abstract A securing device for securing endotracheal tubes to a person, and for securing similar tubes extending from body cavities, is formed of a noose in a thin-walled elastomeric tubing by means of the passage of ends of the tubing through a ring of a thick-walled tubular section. Friction between the foregoing elements and between the noose and the tube secure the device to the tube. Free ends of the tubing are passed around the body of the person to be tied or secured by means of a clamp inserted into one end of the tubing.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
162 words
A device for securing a tube extending from a body, said device comprising: a thin-walled tubing of elastomeric material; a ring formed of a rigid tubular section; a noose formed by the passage of said tubing through said ring, said noose being adapted for encircling said tube without occluding same; said tubing being of such a size that when pulled to a snug fit flattens out against the wall of said tube, thereby increasing the surface contact area and thus the total frictional force between said tube and said tubing resulting in a secure slip-proof grip of said noose about said tube extending from said body; the ends of said tubing being flexibly extendable about a portion of said body for engagement with each other by means secured to at least one end of said tubing so as to secure said tube to said body; and said ring being made of an elastomeric material having a durometer in the range of 75-85.
Claim 2
Independent Claim
162 words
A device for securing a tube extending from a body, said device comprising: a thin-walled tubing of elastomeric material; a ring formed of a rigid tubular section; a noose formed by the passage of said tubing through said ring, said noose being adapted for encircling said tube without occluding same; said tubing being of such a size that when pulled to a snug fit flattens out against the wall of said tube, thereby increasing the surface contact area and thus the total frictional force between said tube and said tubing resulting in a secure slip-proof grip of said noose about said tube extending from said body; the ends of said tubing being flexibly extendable about a portion of said body for engagement with each other by means secured to at least one end of said tubing so as to secure said tube to said body; and said ring being made of an elastomeric material having a durometer in the range of 75-85.
Claim 3
Independent Claim
19 words
A device according to claims 1, wherein a loop of the noose comprises a plurality of strands of tubing.
Claim 4
Dependent Claim
13 words
A device according to claim 2, wherein said noose is a double noose.
Claim 5
Dependent Claim
31 words
A device according to claim 1, wherein said elastomeric material is a plastic selected from the group comprising a plasticized polyvinyl chloride polyurethane, co-polymers of polyethylene and other like elastomeric materials.
Claim 6
Dependent Claim
30 words
A device according to claim 1, wherein said thin-walled tubing comprises a tubular material having a wall thickness no greater than 15% of the outside diameter of said tubular material.
Claim 7
Independent Claim
169 words
A device for securing a tube extending from a body, said device comprising: a thin-walled tubing of elastomeric material; a ring formed of a rigid tubular section; a noose formed by the passage of said tubing through said ring, said noose being adapted for encircling said tube without occluding same; said tubing being of such a size that when pulled to a snug fit flattens out against the wall of said tube, thereby increasing the surface contact area and thus the total frictional force between said tube and said tubing resulting in a secure slip-proof grip of said noose about said tube extending from said body; the ends of said tubing being flexibly extendable about a portion of said body for engagement with each other by means secured to at least one end of said tubing so as to secure said tube to said body; and said thin-walled tubing comprising a tubular material having a wall thickness no greater than 15% of the outside diameter of said tubular material.
Claim 8
Independent Claim
169 words
A device for securing a tube extending from a body, said device comprising: a thin-walled tubing of elastomeric material; a ring formed of a rigid tubular section; a noose formed by the passage of said tubing through said ring, said noose being adapted for encircling said tube without occluding same; said tubing being of such a size that when pulled to a snug fit flattens out against the wall of said tube, thereby increasing the surface contact area and thus the total frictional force between said tube and said tubing resulting in a secure slip-proof grip of said noose about said tube extending from said body; the ends of said tubing being flexibly extendable about a portion of said body for engagement with each other by means secured to at least one end of said tubing so as to secure said tube to said body; and said thin-walled tubing comprising a tubular material having a wall thickness no greater than 15% of the outside diameter of said tubular material.
Claim 9
Dependent Claim
19 words
A device according to claim 6, wherein a loop of the noose comprises a plurality of strands of tubing.
Claim 10
Dependent Claim
13 words
A device according to claim 7, wherein said noose is a double noose.
Claim 11
Dependent Claim
23 words
A device according to claim 6, wherein said ring is made of an elastomeric material having a durometer in the range of 75-85.
Claim 12
Independent Claim
149 words
A device for securing a tube extending from a body, said device comprising: a thin-walled tubing of elastomeric material; a ring formed of a rigid tubular section; a noose formed by the passage of said tubing through said ring, said noose being adapted for encircling said tube without occluding same; said tubing being of such a size that when pulled to a snug fit flattens out against the wall of said tube, thereby increasing the surface contact area and thus the total frictional force between said tube and said tubing resulting in a secure slip-proof grip of said noose about said tube extending from said body; the ends of said tubing being flexibly extendable about a portion of said body for engagement with each other by means of interlocking hook and loop elements provided on the ends of said tubing so as to secure said tube to said body.
Claim 13
Independent Claim
149 words
A device for securing a tube extending from a body, said device comprising: a thin-walled tubing of elastomeric material; a ring formed of a rigid tubular section; a noose formed by the passage of said tubing through said ring, said noose being adapted for encircling said tube without occluding same; said tubing being of such a size that when pulled to a snug fit flattens out against the wall of said tube, thereby increasing the surface contact area and thus the total frictional force between said tube and said tubing resulting in a secure slip-proof grip of said noose about said tube extending from said body; the ends of said tubing being flexibly extendable about a portion of said body for engagement with each other by means of interlocking hook and loop elements provided on the ends of said tubing so as to secure said tube to said body.
