Abstract

Abstract Apparatus for endotracheal and esophageal intubation embodying an elongated tubular member having a first portion with an open outer end and a second portion with an open inner end and a lumen extending therebetween. A first inflatable member is carried about the second portion of the tubular member for inflation within a body canal to form a seal with the walls thereof. A second inflatable member within the lumen seals the lumen when inflated and an air control unit between the outer end of the tubular member and the second inflatable member selectively communicates the lumen with the exterior of the first portion.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 310 words
Apparatus for endotracheal and esophageal intubation comprising: (a) an elongated tubular member having a first portion with an open outer end and a second portion with an open inner end and a lumen extending between said outer and inner ends, (b) a first inflatable member carried about the outer walls of said second portion of said tubular member in spaced relation to said inner end for inflation within a body canal to form a seal with the walls thereof, (c) a second inflatable member mounted within said lumen of said tubular member for sealing said lumen when inflated, (d) a plurality of discharge openings through the walls of said first portion of said tubular member between said outer end and said second inflatable member, (e) a tubular insert of a size to telescope into said open outer end of said first portion of said tubular member with one end of said insert projecting outwardly of said open outer end of said first portion, (f) at least one discharge opening through the walls of said insert in position to move into alignment and communication with said discharge openings in said first portion upon movement of said insert to one position and to move out of alignment and communication with said discharge openings in said first portion upon movement of said insert to another position, (g) a laterally extending flange carried by said first portion of said tubular member adjacent the outer open end thereof, (h) a laterally extending flange carried by said insert in position to extend alongside said flange carried by said first portion, and (i) a projection carried by one laterally extending flange and angularly spaced recesses in the other laterally extending flange with said projection being adapted to snap into a selected angularly spaced recess to retain said insert selectively in said one portion and said another position.

Dependent Claim 310 words
Apparatus for endotracheal and esophageal intubation comprising: (a) an elongated tubular member having a first portion with an open outer end and a second portion with an open inner end and a lumen extending between said outer and inner ends, (b) a first inflatable member carried about the outer walls of said second portion of said tubular member in spaced relation to said inner end for inflation within a body canal to form a seal with the walls thereof, (c) a second inflatable member mounted within said lumen of said tubular member for sealing said lumen when inflated, (d) a plurality of discharge openings through the walls of said first portion of said tubular member between said outer end and said second inflatable member, (e) a tubular insert of a size to telescope into said open outer end of said first portion of said tubular member with one end of said insert projecting outwardly of said open outer end of said first portion, (f) at least one discharge opening through the walls of said insert in position to move into alignment and communication with said discharge openings in said first portion upon movement of said insert to one position and to move out of alignment and communication with said discharge openings in said first portion upon movement of said insert to another position, (g) a laterally extending flange carried by said first portion of said tubular member adjacent the outer open end thereof, (h) a laterally extending flange carried by said insert in position to extend alongside said flange carried by said first portion, and (i) a projection carried by one laterally extending flange and angularly spaced recesses in the other laterally extending flange with said projection being adapted to snap into a selected angularly spaced recess to retain said insert selectively in said one portion and said another position.
Claim 3
Dependent Claim 37 words
Apparatus as defined in claim 1 in which said angularly spaced recesses are in the flange carried by said first portion of said elongated member and said projection is mounted on the flange carried by said insert.
