Endotracheal tube clamp

Claim 2

A disposable clamp for holding an endotracheal tube, comprising a pair of U-shaped clamping members each having a yoke portion and a pair of longitudinally extending parallel limb portions, and means associated with portions of said clamping members securing an attachment band to the clamping members, the clamping members being superimposed to define between the yoke portions and limb portions thereof an aperture for receiving the endotracheal tube, each clamping member defining a pair of longitudinally extending wall portions engaging the pair of longitudinally extending wall portions of the other clamping member, for retaining the members in superimposed relationship, each clamping member defining at least one longitudinally extending wall portion of sawtooth profile positioned to lockingly engage the corresponding sawtooth profiled wall portion of the other clamping member for preventing release of the clamping members, and one of the clamping members being formed with a line of weakness to permit said one member to be broken readily in order to separate the clamping members.

Claim 3

A disposable clamp for holding an endotracheal tube comprising a. a first U-shaped clamping member having a yoke portion, a pair of parallel longitudinally extending limb portions, and a projection integral with said yoke portion, the projection defining a first pair of longitudinally extending parallel walls of sawtooth profile, b. a second U-shaped clamping member having a yoke portion and a pair of parallel longitudinally extending limb portions, the limb portions providing a second pair of longitudinally extending parallel walls of sawtooth profile lockingly engaged with said sawtooth profiled portions of said first pair of walls, c. means associated with portions of said first and second clamping members for securing an attachment band define the clamping members, d. the clamping members being superimposed to define between the yoke portions and limb portions thereof an aperture for receiving the endotracheal tube, said pairs of parallel walls mutually engaging one another to prevent release of the clamping members, e. said clamping members being of interfitting dovetail formation for retaining the clamping members in superimposed relationship, and f. one of the clamping members having a line of weakness to permit said one Member to be broken readily in order to separate the clamping members.

Claim 4

A disposable clamp for holding an endotracheal tube comprising a. a first U-shaped clamping member having a yoke portion, a pair of parallel longitudinally extending limb portions, and a projection integral with said yoke portion, the projection defining a first pair of longitudinally extending parallel walls of sawtooth profile, b. a second U-shaped clamping member having a yoke portion and a pair of parallel longitudinally extending limb portions, the limb portions providing a second pair of longitudinally extending parallel walls of sawtooth profile lockingly engaged with said sawtooth profiled portions of said first pair of walls, c. means associated with portions of said first and second clamping members for securing an attachment band define the clamping members, d. the clamping members being superimposed to define between the yoke portions and limb portions thereof an aperture for receiving the endotracheal tube, said pairs of parallel walls mutually engaging one another to prevent release of the clamping members, e. said clamping members being of interfitting dovetail formation for retaining the clamping members in superimposed relationship, and f. one of the clamping members having a line of weakness to permit said one Member to be broken readily in order to separate the clamping members.

Claim 5

A disposable clamp for holding an endotracheal tube, comprising a. a first U-shaped clamping member having a yoke portion, a pair of longitudinally extending limb portions, a flat upper surface, and a projection from said flat upper surface, the projection defining a first pair of parallel longitudinally extending walls of sawtooth profile, b. a second U-shaped clamping member having a yoke portion, a pair of longitudinally extending limb portions, a flat lower surface, and a projection from said flat lower surface, the limb portions defining a second pair of longitudinally extending walls of sawtooth profile lockingly engaged with said sawtooth profiled portions of said first pair of walls, and the projection defining a pair of longitudinally extending retaining edges engageable with the limb portions of the first clamping member, c. means associated with portions of said first and second clamping members securing an attachment band to the clamping members, d. the clamping members being assembled with the flat surfaces thereof superimposed to define between the yoke portions and limb portions an aperture for receiving the endotracheal tube, said clamping members being retained in assembled relation by the mutual engagement of said pairs of longitudinally extending wall portions and by engagement of said retaining edges with the limb portions of the first clamping member, e. one of the clamping members having a line of weakness to permit said one member to be broken readily in order to separate the clamping members.

Claim 6

A disposable clamp for holding an endotracheal tube, comprising a. a first U-shaped clamping member having a yoke portion, a pair of longitudinally extending limb portions, a flat upper surface, and a projection from said flat upper surface, the projection defining a first pair of parallel longitudinally extending walls of sawtooth profile, b. a second U-shaped clamping member having a yoke portion, a pair of longitudinally extending limb portions, a flat lower surface, and a projection from said flat lower surface, the limb portions defining a second pair of longitudinally extending walls of sawtooth profile lockingly engaged with said sawtooth profiled portions of said first pair of walls, and the projection defining a pair of longitudinally extending retaining edges engageable with the limb portions of the first clamping member, c. means associated with portions of said first and second clamping members securing an attachment band to the clamping members, d. the clamping members being assembled with the flat surfaces thereof superimposed to define between the yoke portions and limb portions an aperture for receiving the endotracheal tube, said clamping members being retained in assembled relation by the mutual engagement of said pairs of longitudinally extending wall portions and by engagement of said retaining edges with the limb portions of the first clamping member, e. one of the clamping members having a line of weakness to permit said one member to be broken readily in order to separate the clamping members.

Claim 7

A disposable clamp according to claim 3, wherein the means securing the attachment band to the clamping members is an integral tab formed on a limb member of each clamping member.

Claim 8

A disposable clamp according to claim 3, wherein the clamping members are of moulded plastics material.
