Abstract

Abstract An adjustably flexible guide is provided to aid in the insertion of a tubular-type device into a body duct or passage. The guide is especially suitable for use by an anesthesiologist in inserting an endotracheal tube for administering anesthetic gases in connection with respiratory care and resuscitation. The guide includes a flexible tube member with a rod member inserted therein. The rod member is slidable within the tube member, and the rod member and the tube member are firmly connected at the tip of the distal ends thereof. A handle means permits the rod member to move longitudinally within the tube member, which produces an arcuate bending of the distal end of the guide. The arcuate bending is facilitated by one or more slots provided in a portion of the surface of the tube member and in a portion of the rod member. Through manipulation of the handle, the anesthesiologist is able to selectively curve the distal end of the guide to permit its insertion in the desired duct or body passage, after which a tubular-type device, such as an endotracheal tube, is slid along the guide. The guide may be removed leaving the tubular-type device in the desired location.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 96 words
An adjustably flexible intubation guide for assisting in the introduction of a tubular device into a body passage, comprising: a tube member; a rod member slidably disposed within and longitudinally movable with respect to the tube member; a fastening means firmly joining the distal tips of the tube member and rod member; a handle means slidably joining the proximal ends of the tube member and rod member; at least one slot peripherally disposed in the distal portion of the tube member; and at least one oppositely disposed slot in the distal portion of the rod member.
Claim 2
Dependent Claim 96 words
An adjustably flexible intubation guide for assisting in the introduction of a tubular device into a body passage, comprising: a tube member; a rod member slidably disposed within and longitudinally movable with respect to the tube member; a fastening means firmly joining the distal tips of the tube member and rod member; a handle means slidably joining the proximal ends of the tube member and rod member; at least one slot peripherally disposed in the distal portion of the tube member; and at least one oppositely disposed slot in the distal portion of the rod member.
Claim 3
Dependent Claim 44 words
The intubation guide as claimed in claim 1, wherein said proximal portion of the tube member is of hollow cross section, and said distal portion of the tube member is of partially hollow cross section; and said rod member is of solid cross section.
Claim 4
Dependent Claim 26 words
The intubation guide as claimed in claim 2, wherein said slot of the rod member extends for substantially the entire length of the distal portion thereof.
Claim 5
Dependent Claim 26 words
The intubation guide as claimed in claim 1, wherein said tube member is of hollow cross section; and said rod member is of solid cross section.
Claim 6
Dependent Claim 26 words
The intubation guide as claimed in claim 1, wherein said tube member is of hollow cross section; and said rod member is of hollow cross section.
Claim 7
Dependent Claim 83 words
The intubation guide as claimed in claim 1, wherein said handle means comprises a stationary element connected to said tube member and a longitudinally slidable member connected to said rod member, whereby the distal portion of said guide is curved in a substantially arcuate upward direction as said slidable member is pushed toward the distal end, and whereby the distal portion of said guide is bent in a substantially arcuate downward direction as said slidable member is moved away from the distal end.
Claim 8
Dependent Claim 32 words
The intubation guide as claimed in claim 1, wherein said tube member has a plurality of slots, the slot nearest the proximal portion thereof being shallower than the rest of said slots.
Claim 9
Dependent Claim 48 words
The intubation guide as claimed in claim 1, wherein said tube member has a plurality of slots, the slots disposed in the extreme distal portion being larger in depth and lateral length and being more closely spaced than the slots disposed in the remainder of the distal portion.
Claim 10
Dependent Claim 128 words
The intubation guide as claimed in claim 1, wherein said tube member has a plurality of slots, first slots disposed in the extreme distal portion being along one side thereof and second slots disposed in the remainder of the distal portion being along the opposite side thereof; and wherein said rod member has a plurality of slots, first slots disposed in the extreme distal portion thereof being along one side thereof so that said first slots of said rod member are opposite said first slots in said tube member and second slots disposed in the remainder of the distal portion of said rod member being along the opposite side thereof so that the second slots of said rod member are opposite said second slots in said tube member.
Claim 11
Dependent Claim 45 words
The intubation guide as claimed in claim 1, wherein said tube member is hollow throughout, both the distal tip and the proximal end thereof being open; and wherein said rod member is hollow throughout, both the distal tip and the proximal end thereof being open.
