Abstract
Abstract A tracheal tube for use in intubating a trachea, and which embodies passageways and openings therein which are constituted and arranged in a manner particularly effective for the passage of suction catheters, and the like, therethrough into bronchi, and the like. The tube preferably embodies a cuff mounted on the end and sides thereof for effecting a seal between the tube and the trachea, and for protecting the trachea against injury. The cuff embodies resilient means for maintaining it in expanded position, and is contractible by means of a vacuum applied thereinto by a secondary tube mounted on the tracheal tube.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
164 words
A tracheal tube comprising a. an elongated tube having 1. a distal end portion having a. an end wall, 2. a proximal end, and 3. a passageway extending longitudinally through said proximal end into said distal end portion, b. said distal end portion 1. being narrower in width transversely to the length of said tube than the portion of said tube adjacent said distal end portion, and 2. having a transverse opening therein in communication with said passageway, c. said transverse opening 1. being defined on one side by said end wall, and 2. extending from said end wall toward said proximal end, and d. a cuff (1) mounted on and extending around the outer surface of said portion of said tube which is adjacent to said distal end portion, and also (2) mounted on and extending along the outer surface of said end wall outwardly of said opening, said cuff having means therein normally expanding said cuff away from both said outer surfaces.
Claim 2
Dependent Claim
164 words
A tracheal tube comprising a. an elongated tube having 1. a distal end portion having a. an end wall, 2. a proximal end, and 3. a passageway extending longitudinally through said proximal end into said distal end portion, b. said distal end portion 1. being narrower in width transversely to the length of said tube than the portion of said tube adjacent said distal end portion, and 2. having a transverse opening therein in communication with said passageway, c. said transverse opening 1. being defined on one side by said end wall, and 2. extending from said end wall toward said proximal end, and d. a cuff (1) mounted on and extending around the outer surface of said portion of said tube which is adjacent to said distal end portion, and also (2) mounted on and extending along the outer surface of said end wall outwardly of said opening, said cuff having means therein normally expanding said cuff away from both said outer surfaces.
Claim 3
Dependent Claim
4 words
a proximal end, and
Claim 4
Dependent Claim
4 words
a proximal end, and
Claim 5
Dependent Claim
14 words
having a transverse opening therein in communication with said passageway, c. said transverse opening
Claim 6
Dependent Claim
14 words
having a transverse opening therein in communication with said passageway, c. said transverse opening
Claim 7
Dependent Claim
70 words
extending from said end wall toward said proximal end, and d. a cuff (1) mounted on and extending around the outer surface of said portion of said tube which is adjacent to said distal end portion, and also (2) mounted on and extending along the outer surface of said end wall outwardly of said opening, said cuff having means therein normally expanding said cuff away from both said outer surfaces.
Claim 8
Dependent Claim
70 words
extending from said end wall toward said proximal end, and d. a cuff (1) mounted on and extending around the outer surface of said portion of said tube which is adjacent to said distal end portion, and also (2) mounted on and extending along the outer surface of said end wall outwardly of said opening, said cuff having means therein normally expanding said cuff away from both said outer surfaces.
Claim 9
Dependent Claim
84 words
A tracheal tube as defined in claim 1, and in which a. said transverse opening extends through two opposite sides of said distal end portion, b. said distal end portion includes two oppositely disposed side walls extending from said end wall toward said proximal end in spaced relation to each other, c. said side walls define respective opposite sides of said opening, and d. said cuff is mounted on and extends along the outer peripheral surface of said side walls outwardly of said opening.
Claim 10
Dependent Claim
111 words
a resilient body portion a. mounted in said cover, and b. having (1'') normally an expanded position, wherein it is effective to hold a portion of said cover outwardly away from said portion and walls of said elongated tube, and (2'') a collapsed position, wherein the outer surface thereof is disposed closer to said elongated tube than in said expanded position to thereby permit said portion of said cover to assume a position closer to said elongated tube, and b. which includes means connected to said cuff for creating and releasing a vacuum in said cover to thereby cause said body portion to move toward said collapsed and expanded positions, respectively.
Claim 11
Dependent Claim
111 words
a resilient body portion a. mounted in said cover, and b. having (1'') normally an expanded position, wherein it is effective to hold a portion of said cover outwardly away from said portion and walls of said elongated tube, and (2'') a collapsed position, wherein the outer surface thereof is disposed closer to said elongated tube than in said expanded position to thereby permit said portion of said cover to assume a position closer to said elongated tube, and b. which includes means connected to said cuff for creating and releasing a vacuum in said cover to thereby cause said body portion to move toward said collapsed and expanded positions, respectively.
Claim 12
Dependent Claim
26 words
A tracheal tube as defined in claim 2, and in which a. said distal end portion extends along the longitudinal center line of said elongated tube.
Claim 13
Dependent Claim
18 words
a passageway extending longitudinally through said proximal end into said distal end portion, b. said distal end portion
Claim 14
Dependent Claim
18 words
a passageway extending longitudinally through said proximal end into said distal end portion, b. said distal end portion
Claim 15
Dependent Claim
68 words
A tracheal tube as defined in claim 3, and in which a. said cuff has 1 a normal position wherein it is disposed in outwardly expanded position relative to said elongated tube, and 2 another position wherein it extends a lesser distance from said elongated tube than in said normal position, and b. said cuff includes resilient means for normally yieldingly holding said cuff in said normal position.
Claim 16
Dependent Claim
15 words
A tracheal tube as defIned in claim 3, and a. in which said cuff comprises
