Abstract
Abstract An enema administering apparatus insertable into the rectum for delivery of a contrast medium to internal portions of a patient's anatomy includes an enema tube joined to an enema tip wherein the enema tube and enema tip have a common contrast medium passageway extending therethrough and an air passageway which is exterior of the contrast medium passageway and is able to be coupled to a source of air for double contrast studies. The air passageway may be a passageway disposed within the enema tube and enema tip construction or may be a separate tubing member joined therewith in a suitable arrangement to introduce air for the double contrast studies once the barium has been evacuated from the patient. Air introduction means and contrast medium introduction means are provided by various arrangements suitable for use with the main enema administering apparatus concept disclosed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
75 words
An enema-administering related device for use with an enema-administering tip and stem for the purpose of conducting double contrast studies, said device comprising: cuff means adapted to be independently assembled to and removed from said enema-administering stem, said cuff means including an air delivery passageway disposed therein and extending therethrough; an inflatable annular element disposed about the periphery of said cuff means; and an air tube being adapted for air inflation of said annular element.
Claim 2
Dependent Claim
75 words
An enema-administering related device for use with an enema-administering tip and stem for the purpose of conducting double contrast studies, said device comprising: cuff means adapted to be independently assembled to and removed from said enema-administering stem, said cuff means including an air delivery passageway disposed therein and extending therethrough; an inflatable annular element disposed about the periphery of said cuff means; and an air tube being adapted for air inflation of said annular element.
Claim 3
Dependent Claim
18 words
The device of claim 1 wherein said device is molded as a single integral member from synthetic material.
Claim 4
Dependent Claim
91 words
An enema-administering related device for use with an enema-administering tip and stem for the purpose of conducting double contrast studies, said device comprising: cuff means adapted to be independently assembled to and removed from said enema-administering stem, said cuff means including an air delivery passageway disposed therein and extending therethrough; and an enlarged tip portion having a contrast medium passageway extending therethrough, said tip portion further having air delivery means flow coupled to said air delivery passageway, said air delivery means being adapted to provide air for said double contrast studies.
Claim 5
Dependent Claim
91 words
An enema-administering related device for use with an enema-administering tip and stem for the purpose of conducting double contrast studies, said device comprising: cuff means adapted to be independently assembled to and removed from said enema-administering stem, said cuff means including an air delivery passageway disposed therein and extending therethrough; and an enlarged tip portion having a contrast medium passageway extending therethrough, said tip portion further having air delivery means flow coupled to said air delivery passageway, said air delivery means being adapted to provide air for said double contrast studies.
Claim 6
Dependent Claim
18 words
The device of claim 3 wherein said device is molded as a single integral member from synthetic material.
Claim 7
Dependent Claim
30 words
The device of claim 3 wherein said cuff means further includes an inflatable annular element and an air tube, said tube being adapted for air inflation of said annular element.
Claim 8
Dependent Claim
18 words
The device of claim 5 wherein said device is molded as a single integral member from synthetic material.
Claim 9
Dependent Claim
127 words
An enema-administering related device for use with an enema-administering tip and stem for the purpose of conducting double contrast studies, said device comprising: cuff means adapted to be independently assembled to and removed from said enema-administering stem, said cuff means including an air delivery passageway disposed therein and extending therethrough; said cuff means further includes a stem-receiving portion and a collar portion spaced apart from said stem-receiving portion, said air delivery passageway being disposed in and extending through said collar portion; and a flexible hollow tube, said flexible hollow tube being slidably received within said air delivery passageway, said flexible hollow tube having a length sufficient for said tube to extend from a first location remote from said tip to an air delivery location adjacent said tip.
Claim 10
Dependent Claim
127 words
An enema-administering related device for use with an enema-administering tip and stem for the purpose of conducting double contrast studies, said device comprising: cuff means adapted to be independently assembled to and removed from said enema-administering stem, said cuff means including an air delivery passageway disposed therein and extending therethrough; said cuff means further includes a stem-receiving portion and a collar portion spaced apart from said stem-receiving portion, said air delivery passageway being disposed in and extending through said collar portion; and a flexible hollow tube, said flexible hollow tube being slidably received within said air delivery passageway, said flexible hollow tube having a length sufficient for said tube to extend from a first location remote from said tip to an air delivery location adjacent said tip.
Claim 11
Dependent Claim
18 words
The device of claim 7 wherein said device is molded as a single integral member from synthetic material.
Claim 12
Dependent Claim
31 words
The device of claim 7 wherein said cuff means further includes an inflatable annular element and an air tube, said air tube being adapted for air inflation of said annular element.
Claim 13
Dependent Claim
18 words
