Abstract

Abstract An endotracheal tube and holder comprising a flexible elongated endotracheal tube for insertion through a patient's mouth down into the patient's trachea to facilitate opening of the airways and a holder to keep the endotracheal tube in place after it has been appropriately inserted. The holder in accordance with this invention comprises a short sleeve having an inner diameter corresponding to the outer diameter of the endotracheal tube and slightly larger to permit the endotracheal tube to slide within the sleeve but still be held snugly within the sleeve when the tube is secured thereto, the sleeve portion of the holder being integrally connected to a base portion which comprises a relatively thin flat strip of flexible sheet material extending outwardly from each side of the sleeve. The outer end of the endotracheal tube has formed thereon a gear rack and the sleeve of the holder includes a pinion gear mounted for rotation on the sleeve wall with the gear teeth extending into the passageway of the sleeve a sufficient distance to engage the corresponding teeth of the gear rack on the endotracheal tube. A knob is attached to the pinion gear whereby the physician can rotate the pinion gear and move the endotracheal tube outwardly from the patient's trachea a pre-selected distance and back inwardly of the patient's trachea by rotating the pinion gear in the opposite direction.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 263 words
An endotracheal tube and holder comprising an elongated tubular member having a first outer end and a second insertable end to insert into the trachea of a patient, a holding member to hold said elongated tubular member in place when so inserted, said holding member including first elongated retaining means to frictionally engage an elongated peripheral wall portion of said elongated tubular member to hold it against any substantial lateral movement relative to said holding member, and second retaining means to hold said tubular member against any substantial longitudinal movement relative to said holding member, wherein said first elongated retaining means of said holding member comprises a tubular sleeve portion, said elongated tubular member being slidably received in said tubular sleeve portion, wherein said elongated tubular member includes an elongated gear rack positioned on its outer wall, longitudinally thereof, extending from a point inwardly of said first outer end toward said first outer end, and wherein said second retaining means includes a pinion gear rotatably mounted along the outer wall of said tubular sleeve portion of said holding member, an opening in said outer wall to permit gear teeth of said pinion gear to extend through said opening into the tubular passageway of said tubular sleeve portion to engage the gear teeth of said gear rack when said elongated tubular member is inserted through said passageway with its said gear rack positioned to face and engage said gear teeth of said pinion gear, said pinion gear thereby holding said tubular member against any substantial longitudinal movement relative to said holding member until rotated.
Claim 2
Dependent Claim 263 words
An endotracheal tube and holder comprising an elongated tubular member having a first outer end and a second insertable end to insert into the trachea of a patient, a holding member to hold said elongated tubular member in place when so inserted, said holding member including first elongated retaining means to frictionally engage an elongated peripheral wall portion of said elongated tubular member to hold it against any substantial lateral movement relative to said holding member, and second retaining means to hold said tubular member against any substantial longitudinal movement relative to said holding member, wherein said first elongated retaining means of said holding member comprises a tubular sleeve portion, said elongated tubular member being slidably received in said tubular sleeve portion, wherein said elongated tubular member includes an elongated gear rack positioned on its outer wall, longitudinally thereof, extending from a point inwardly of said first outer end toward said first outer end, and wherein said second retaining means includes a pinion gear rotatably mounted along the outer wall of said tubular sleeve portion of said holding member, an opening in said outer wall to permit gear teeth of said pinion gear to extend through said opening into the tubular passageway of said tubular sleeve portion to engage the gear teeth of said gear rack when said elongated tubular member is inserted through said passageway with its said gear rack positioned to face and engage said gear teeth of said pinion gear, said pinion gear thereby holding said tubular member against any substantial longitudinal movement relative to said holding member until rotated.
Claim 3
Dependent Claim 88 words
An endotracheal tube and holder as set forth in claim 1, wherein said pinion gear includes hand grasp means connected thereto for a user to manually grasp and rotate said pinion gear in engagement with said rack of said elongated tubular member, whereby said elongated tubular member may be moved longitudinally in the direction outwardly of a patient's trachea when said pinion gear is rotated in one direction and in the opposite direction inwardly of said patient's trachea when said pinion gear is rotated in the opposite direction.
Claim 4
Dependent Claim 42 words
An endotracheal tube and holder as set forth in claim 2, including markings on said elongated tubular member adjacent said gear rack to measure and indicate the distance said elongated tubular member may be moved longitudinally relative to said tubular sleeve portion.
Claim 5
Dependent Claim 51 words
An endotracheal tube and holder as set forth in claim 1, wherein said elongated tubular member is made of a relatively soft, flexible polymeric material, said gear rack is made of a relatively hard rigid polymeric material, said rack being bonded to the outer side wall of said elongated tubular member.
