Abstract
Abstract A suction control arrangement for a suction catheter having a body portion with a passageway formed longitudinally therethrough and a port means formed therein to provide access to the interior of the passageway, and having a cap means mounted on the body portion with an opening formed in it. The cap means is movable on the body portion such that the opening in the cap means and the port in the body portion may be aligned to eliminate suction through the passageway and the body means when the body means is attached at its opposite ends to suction conduit means in a suction catheter system. Alternately, the cap means may be moved to a closed position over the port means to establish suction in the system. The body portion and cap means have cooperative locking means to maintain the cap means in selected open or closed position with respect to the body portion.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
193 words
A suction control arrangement for a suction catheter comprising: a body portion interconnecting two sections of the suction catheter; fluid conduit means formed in said body portion and providing a continuous flow path between the two sections of the suction catheter; port means formed in said body portion to provide access from the exterior of said body portion to said fluid conduit means; cap means mounted on said body portion for linear movement relative thereto; an openiNg formed in said cap means, movement of said cap means with respect to said body portion resulting in a desired amount of alignment between said opening and said port means to control the suction applied by the suction catheter; gripping means formed on said body portion and on said cap means to permit said cap means to be moved with respect to said body portion by one band of an operator; and complementary means formed on said body portion and said cap means to provide for selectively positioning said cap means at various relationships of said opening and said port means and to maintain said cap means in the slected positions to provide a constant suction.
Claim 2
Dependent Claim
193 words
A suction control arrangement for a suction catheter comprising: a body portion interconnecting two sections of the suction catheter; fluid conduit means formed in said body portion and providing a continuous flow path between the two sections of the suction catheter; port means formed in said body portion to provide access from the exterior of said body portion to said fluid conduit means; cap means mounted on said body portion for linear movement relative thereto; an openiNg formed in said cap means, movement of said cap means with respect to said body portion resulting in a desired amount of alignment between said opening and said port means to control the suction applied by the suction catheter; gripping means formed on said body portion and on said cap means to permit said cap means to be moved with respect to said body portion by one band of an operator; and complementary means formed on said body portion and said cap means to provide for selectively positioning said cap means at various relationships of said opening and said port means and to maintain said cap means in the slected positions to provide a constant suction.
Claim 3
Dependent Claim
90 words
A suction control arrangement as claimed in claim 1 wherein: said body portion comprises guide means formed thereon and extending longitudinally therealong; and said cap means comprises channel-shaped slide means mounted on said guide means for sliding movement therealong, said slide means being movable longitudinally along said guide means with respect to said body portion to allow said opening formed in said slide means to be moved to selected positions with respect to said port means to control the suction and thereby the fluid flow through said fluid conduit means.
Claim 4
Dependent Claim
76 words
A suction control arrangement as claimed in claim 1 wherein said complementary means comprises: notches formed in said body portion transverse to the longitudinal axis thereof; and ribs formed in said cap means to selectively engage desired ones of said notches, engagement of said ribs and said notches being effective to stop and lock said cap means in a selected position with respect to said body portion to provide a constant suction of a controlled magnitude.
Claim 5
Dependent Claim
258 words
A suction control arrangement for a suction catheter comprising: an extended body portion; attachment means formed at each end of said body portion to provide a fluid tight engagement between said body portion and two sections of the suction catheter; fluid conduit means formed in said body portion and providing a continuous flow path between the two sections of the suction catheter; a projecting guide means extending along the length of one side of said body portion; a port formed in said projecting guide means and said body portion to provide access from the exterior of said body portion to said fluid conduit means; channel-shaped slide means formed on said cap means to engage said projecting guide means on said body portion to provide for sliding movement between said body portion and said cap means, movement of said cap means with respect to said body portion resulting in varying degrees of alignment between said opening in said cap means and said port in said body portion to cause the suction catheter to produce a desired amount of suction; complementary means formed on said body portion and said cap means to provide for selectively positioning said cap means at various relationships of said opening and said port and to maintain said cap means in the selected positions to provide a constant suction of a desired magnitude; and gripping means formed on said body portion and on said cap means to permit said cap means to be moved with respect to said body portion by one hand of an operator.
Claim 6
Dependent Claim
258 words
A suction control arrangement for a suction catheter comprising: an extended body portion; attachment means formed at each end of said body portion to provide a fluid tight engagement between said body portion and two sections of the suction catheter; fluid conduit means formed in said body portion and providing a continuous flow path between the two sections of the suction catheter; a projecting guide means extending along the length of one side of said body portion; a port formed in said projecting guide means and said body portion to provide access from the exterior of said body portion to said fluid conduit means; channel-shaped slide means formed on said cap means to engage said projecting guide means on said body portion to provide for sliding movement between said body portion and said cap means, movement of said cap means with respect to said body portion resulting in varying degrees of alignment between said opening in said cap means and said port in said body portion to cause the suction catheter to produce a desired amount of suction; complementary means formed on said body portion and said cap means to provide for selectively positioning said cap means at various relationships of said opening and said port and to maintain said cap means in the selected positions to provide a constant suction of a desired magnitude; and gripping means formed on said body portion and on said cap means to permit said cap means to be moved with respect to said body portion by one hand of an operator.
Claim 7
Dependent Claim
71 words
A suction control arrangement as claimed in claim 4 wherein said complementary means comprises: notches formed in said body portion transverse to the longitudinal direction thereof; and ribs formed in said cap means for engagement with said notches, engagement of said ribs and said notches resulting in the locking of said cap means at selected positions with respect to said body portion to provide a constant suction of a desired magnitude.
