Abstract
Abstract The invention is concerned with an endotracheal tube holder formed of a generally rigid flat bar having a lateral cut-out leaving a reduced flexible neck connecting the remaining bar portions together for relative swinging about an axis through the neck generally perpendicular to the bar, the cut being configured to conformably receive and circumferentially clamp about a received tube, and one side edge of the bar being provided on respective bar portions with a releasably interengageable catch and a latch which automatically snap into interengagement upon relative swinging movement of the bar portions, all without adversely displacing the tube.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
196 words
A holder for an endotracheal tube, said holder being integrally fabricated of plastic and comprising a substantially rigid elongate flat bar, attachment means at opposite ends of said bar for attachment to a head strap, said bar having a slot entering laterally into one side edge at a location spaced between the ends of said bar and opening through opposite faces of said bar, said slot having an enlarged inner region defining a tube receiving cut-out located adjacent to and spaced from the other side edge of said bar to leave a reduced flexible neck opposite to said slot entering location, said bar being subdivided by said cut-out into substantially rigid portions on opposite sides of said cut-out connected by said neck for relative swinging movement of the bar portions toward and away from each other constrained only about an axis through said neck perpendicular to said bar for gripping and releasing a tube without substantial tube movement, a catch on said one side edge of one bar portion, and a latch on said side edge of the other bar portion and releasably interengagable with said catch when the bar portions are swung toward each other.
Claim 2
Dependent Claim
196 words
A holder for an endotracheal tube, said holder being integrally fabricated of plastic and comprising a substantially rigid elongate flat bar, attachment means at opposite ends of said bar for attachment to a head strap, said bar having a slot entering laterally into one side edge at a location spaced between the ends of said bar and opening through opposite faces of said bar, said slot having an enlarged inner region defining a tube receiving cut-out located adjacent to and spaced from the other side edge of said bar to leave a reduced flexible neck opposite to said slot entering location, said bar being subdivided by said cut-out into substantially rigid portions on opposite sides of said cut-out connected by said neck for relative swinging movement of the bar portions toward and away from each other constrained only about an axis through said neck perpendicular to said bar for gripping and releasing a tube without substantial tube movement, a catch on said one side edge of one bar portion, and a latch on said side edge of the other bar portion and releasably interengagable with said catch when the bar portions are swung toward each other.
Claim 3
Dependent Claim
50 words
An endotracheal tube holder according to claim 1, said cut-out having its internal surface of substantially circular configuration less than 360° by the width of said slot and substantially equally divided between respective bar portions, for equal clamping engagement of the bar portions with a tube received in said cut-out.
Claim 4
Dependent Claim
40 words
An endotracheal tube holder according to claim 1, said catch comprising an undercut facing away from said slot, and said latch comprising an arm extending over said slot and a hook on said arm for retaining engagement with said undercut.
Claim 5
Dependent Claim
56 words
An endotracheal tube holder according to claim 3, said catch comprising a ramp facing outwardly from said one bar portion, and said latch arm being resilient and including a cam facing inwardly towards said ramp and riding over the latter and snapping into said releasable interengagement upon relative swinging of said bar portions toward each other.
Claim 6
Dependent Claim
43 words
An endotracheal tube holder according to claim 4, said neck being resiliently flexible and assuming in its unstressed condition a position displacing said bar portions partially away from each other for free selective longitudinal displacement of a received tube relative to the holder.
Claim 7
Dependent Claim
44 words
An endotracheal tube holder according to claim 4, said ramp being located between said undercut and slot, and said cam being located on said latch arm outwardly beyond said hook, for relative riding of said cam and ramp and snapping into said releasable interengagement.
Claim 8
Dependent Claim
26 words
An endotracheal tube holder according to claim 6, said cut-out being beveled on one face of said bar to facilitate endwise tube insertion into said cut-out.
