Abstract
Abstract An adjustable rectal applicator in which an applicator tube is reciprocable within a sleeve for adjusting its discharge end within the rectum. The sleeve fits closely within the anal canal and is provided on its exterior with a surrounding enlargement that is engageable against a perianal surface to seal the anal opening. Means are provided for maintaining the applicator tube in adjusted position within the sleeve and also to seal the distal end of the sleeve bore. In one form, the applicator tube is formed with longitudinally spaced openings at its discharge end portion. In another form, a nozzle having a soft, resiliently flexible head section and a coupling section is secured to the applicator tube adapted to close the proximal end of the sleeve, and permitting the drainage of the rectum through the sleeve, when in non-closing position through an opening formed in the distal portion of the sleeve.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
156 words
An applicator for administering fluid into the intestinal tract per rectum, comprising a rigid tubular sleeve having an outer circumference adapted to fit snugly within an anal canal and an applicator tube of lesser outer circumfereNce than the inner circumference of said sleeve and freely slidable therewithin; sealing means on the exterior of said sleeve spaced distally from the proximal end thereof adapted to engage against the perianal surface to form a seal around the anal opening through which the proximal portion of said sleeve is inserted, said sealing means comprising a first enlargement on said sleeve having a proximal surface engageable against said perianal surface and a second enlargement on said sleeve of greater dimension than said first enlargement and in distally spaced relation to said first enlargement, said second enlargement having a proximal surface adaPted to engage against said perianal surface, and means adjustably fixing the position of said applicator tube within said sleeve.
Claim 2
Dependent Claim
156 words
An applicator for administering fluid into the intestinal tract per rectum, comprising a rigid tubular sleeve having an outer circumference adapted to fit snugly within an anal canal and an applicator tube of lesser outer circumfereNce than the inner circumference of said sleeve and freely slidable therewithin; sealing means on the exterior of said sleeve spaced distally from the proximal end thereof adapted to engage against the perianal surface to form a seal around the anal opening through which the proximal portion of said sleeve is inserted, said sealing means comprising a first enlargement on said sleeve having a proximal surface engageable against said perianal surface and a second enlargement on said sleeve of greater dimension than said first enlargement and in distally spaced relation to said first enlargement, said second enlargement having a proximal surface adaPted to engage against said perianal surface, and means adjustably fixing the position of said applicator tube within said sleeve.
Claim 3
Dependent Claim
48 words
The applicator of claim 1, wherein said applicator tube is formed with a restricted opening at its proximal end and is provided with spaced openings in opposed wall portions thereof distally of its proximal end, said openings in said opposed wall portions being of graduated, distally increasing size.
Claim 4
Dependent Claim
36 words
The applicator of claim 1, wherein said proximal surfaces of said first and second enlargements are provided with annular ridges surrounding said sleeve, said ridges adapted to be pressed into the tissues of said perianal surface.
Claim 5
Dependent Claim
90 words
The applicator of claim 1, wherein said means for fixedly securing said applicator tube in position within said sleeve comprises a locking collar fitted snugly and slidably over said applicator tube distally of said sleeve, the wall of said collar thickening distally from an outer circumference at its proximal end less than the inner circumference of said sleeve to an outer circumference at its distal end greater than the inner circumference of said sleeve, said collar adapted to be wedged into the distal end of the opening in said sleeve.
Claim 6
Dependent Claim
112 words
The applicator of claim 1, wherein a nozzle assembly is mounted on the proximal end of said applicator tube and comprises integrally formed proximal and distal sections, said proximal section being made of resiliently flexible material and said distal section being made of substantially rigid material which is chemically compatible with said flexible material, said proximal section being substantially dome-shaped and being provided with an outlet opening at its apex and having its open end of an inner diameter adapted to fit over the proximal end of said rigid tubular sleeve, said distal section being a tubular coupling means for mounting said nozzle assembly on said proximal end of said applicator tube.
Claim 7
Dependent Claim
116 words
The applicator of claim 5, wherein said proximal section of said nozzle assembly is formed with an inwardly extending sleeve defining said apical opening therein, and wherein said distal section of said nozzle assembly comprises a proximal tubular end fitting within said inwardly extending sleeve and a frusto-conical enlargement formed on said tubular coupling means, distally of said end thereof, said enlargement tapering distally and arranged to fit within the frontal end of said rigid tubular sleeve when said frontal end of said rigid tubular sleeve is disposed within the opening of said proximal section of said nozzle assembly, and a distally tapering portion of said enlargement engaged within said proximal opening of said applicator tube.
Claim 8
Dependent Claim
93 words
The applicator of claim 6, wherein said means for fixedly securing said applicator tube in position within said sleeve comprises a locking collar fitted snugly and slidably over said applicator tube and is frictionally engaged thereon distally of said sleeve, the wall of said collar thickening distally from an outer circumference less than the inner circumference of said sleeve to an outer circumference at its distal end greater than the inner circumference of said sleeve, said collar adapted to be wedged into the distal end of the bore of said first named sleeve.
Claim 9
Dependent Claim
56 words
The applicator of claim 7, wherein means are provided for draining the intestinal Track through said sleeve around said applicator tube when said nozzle assembly is held in position above the frontal end of said sleeve, said means comprising an opening formed in a wall portion of said sleeve, said opening connectable to a drainage tube.
Claim 10
Dependent Claim
66 words
The applicator of claim 8, wherein a sleeve extension is provided for said sleeve, around said applicator tube, distally of said sleeve and coupled therewith in fluid-tight relation, said sleeve extension having a bore of substantially corresponding size with said sleeve, said opening being formed in the wall of said sleeve extension and said locking collar being fitted into the distal end of said sleeve extension.
Claim 11
Dependent Claim
117 words
A nozzle assembly adapted for use with a rectal applicator, comprising two integrated segments, the first of said segments being a proximal and substantially hollow dome-shaped body of soft, resiliently flexible material, said body having an outlet opening formed therein at its apex, said opening being defined on the interior of said body by a tubular sleeve, and a second segment comprising a distal tubular coupling of substantially rigid material for mounting said nozzle assembly on the end of said rectal applicator, said coupling comprising a proximal tubular end fitting within said tubular sleeve and a frusto-conical enlargement formed on said coupling, said enlargement tapering distally and adapted to engage within the proximal opening of said applicator.
Claim 12
Dependent Claim
117 words
A nozzle assembly adapted for use with a rectal applicator, comprising two integrated segments, the first of said segments being a proximal and substantially hollow dome-shaped body of soft, resiliently flexible material, said body having an outlet opening formed therein at its apex, said opening being defined on the interior of said body by a tubular sleeve, and a second segment comprising a distal tubular coupling of substantially rigid material for mounting said nozzle assembly on the end of said rectal applicator, said coupling comprising a proximal tubular end fitting within said tubular sleeve and a frusto-conical enlargement formed on said coupling, said enlargement tapering distally and adapted to engage within the proximal opening of said applicator.
