Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
178 words
A dual-purpose catheter comprising an elongated tube having an insertion end and a valve connection end, said insertion end adapted for coupling to the human body and said valve connection end adapted for alternate connection to a source of suction or a source of oxygen. adjustable valve means connected to said valve connection end and disposed between said tube and said sources of suction and oxygen, said valve means including therein first and second through-passage means, said first through-passage means being adapted to be disposed (1) in a first position in which it is connected between said suction source and said tube and (2) in a second position in which it is connected between the environment and said suction source, and, when said first through-passage means is in said first position, said second through-passage means is in a first position in which it is connected between the atmosphere and said source of oxygen and, when said first through-passage means is in said second position, said second through-passage means is connected between said tube and said source of oxygen.
Claim 2
Dependent Claim
178 words
A dual-purpose catheter comprising an elongated tube having an insertion end and a valve connection end, said insertion end adapted for coupling to the human body and said valve connection end adapted for alternate connection to a source of suction or a source of oxygen. adjustable valve means connected to said valve connection end and disposed between said tube and said sources of suction and oxygen, said valve means including therein first and second through-passage means, said first through-passage means being adapted to be disposed (1) in a first position in which it is connected between said suction source and said tube and (2) in a second position in which it is connected between the environment and said suction source, and, when said first through-passage means is in said first position, said second through-passage means is in a first position in which it is connected between the atmosphere and said source of oxygen and, when said first through-passage means is in said second position, said second through-passage means is connected between said tube and said source of oxygen.
Claim 3
Dependent Claim
195 words
The apparatus defined in claim 1 wherein said valve means includes a tube having two pairs of holes, a first upper pair and a second lower pair aligned on a longitudinal axis and a second pair of holes, a third upper pair and a fourth lower pair aligned on the opposite longitudinal axis, said third pair of holes being offset upwardly above said first pair of holes, said fourth pair of holes being offset downwardly below said second pair of holes, a first nozzle covering said first pair of holes, a second nozzle covering said second pair of holes, a third nozzle covering the lower hole of said third pair of holes, a fourth nozzle covering the upper hold of said fourth pair of holes, a first passage means between the upper holes of said first and third pairs of holes and adapted to be moved to be disposed between the lower holes of said first and third pairs of holes, and a second passage means between the upper holes of said second and fourth pairs of holes and adapted to be moved to the lower holes of the second and fourth pairs of holes.
Claim 4
Dependent Claim
48 words
The apparatus defined in claim 2 wherein said valve means includes an outer tube and a slidable inner tube disposed within said outer tube, said outer tube carrying said first, second, third and fourth pairs of holes, and said inner tube carrying said first and second passage means.
Claim 5
Dependent Claim
64 words
The apparatus defined in claim 2 and including a spring in said first tube and urging said second tube upwardly out of said first tube, a first stop means in said first tube to limit the downward movement of said inner tube, and a second stop means at the upper end of said first tube to limit the upward movement of said inner tube.
Claim 6
Dependent Claim
15 words
The apparatus defined in claim 3 wherein said first and second tubes have rectangular cross-sections.
Claim 7
Dependent Claim
35 words
The apparatus defined in claim 3 wherein said first and second tubes have circular cross-sections and a mating notch and projection combination to prevent rotation of the second tube with respect to the first tube.
Claim 8
Dependent Claim
122 words
The apparatus defined in claim 1 wherein said valve means includes a first block having a first through passage means for connection to suction and a second through passage means for connection to oxygen, a slidable block positioned adjacent to said first block and having third and fourth through passage means for connection to said tube, said slidable block also having fifth and sixth passage means to the atmosphere, said slide being adapted to occupy (1) a first position in which said second and fourth passage means are aligned and said first and fifth passage means are aligned and (2) a second position in which said first and third passage means are aligned and said second and sixth passage means are aligned.
Claim 9
Dependent Claim
34 words
The apparatus defined in claim 1 wherein said tube assembly comprises first and second tubes coupled at one end to said valve means and coupled together at their other ends to a single catheter.
Claim 10
Dependent Claim
88 words
The apparatus defined in claim 1 wherein said tube assembly includes (1) a first suction catheter having one end coupled to said valve means and the other remote end adapted to be inserted in the body and (2) a second oxygen catheter having one end coupled to said valve means and its other remote end adapted to be inserted in said body but not extending as far as the remote end of the suction catheter, said suction catheter and oxygen catheter being secured together as an unitary assembly.
