Abstract
Abstract A rectal applicator for the administration of an enema as practiced in the roentgen examination of the intestinal tract, comprising a device formed by joining a tubular nozzle section with a tubular stem section. The device is provided at the junction of its two sections with an enlargement, the proximal face of which is formed with concentric annular ridges spaced from the nozzle tube and one another, and engageable against the perianal surface of a body to seal externally the anal opening. In one embodiment, the enlargement with the sealing ridges is integral with the nozzle section and the stem section is provided with an enlargement underlying and supporting the nozzle tube enlargement. In the preferred embodiment a chamber is formed at the junction between the two sections by joining them peripherally into a single structure, with the chamber serving to lend compressibility and adaptability to the device when applied in the depth of the cleft space against the perianal surface, and also serving to receive the contrast fluid.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
An applicator for admininstering a fluid into the intestinal tract per rectum, comprising a tubular nozzle section and a tubular stem section joined to each other to form an integral structure, an enlargement formed at the junction of said nozzle and stem sections and extending normally to the axis of said integral structure, and a chamber within said enlargement to receive contrast fluid therein, and means on the proximal face of said enlargement adapted to be applied against the perianal area of a body into the rectum of which said nozzle is inserted to seal the anal opening thereof, said stem section having a posterior extension for providing indirect sealing of said opening.
Claim 2
Dependent Claim
113 words
An applicator for admininstering a fluid into the intestinal tract per rectum, comprising a tubular nozzle section and a tubular stem section joined to each other to form an integral structure, an enlargement formed at the junction of said nozzle and stem sections and extending normally to the axis of said integral structure, and a chamber within said enlargement to receive contrast fluid therein, and means on the proximal face of said enlargement adapted to be applied against the perianal area of a body into the rectum of which said nozzle is inserted to seal the anal opening thereof, said stem section having a posterior extension for providing indirect sealing of said opening.
Claim 3
Dependent Claim
40 words
The applicator of claim 1, wherein said proximal face of said enlargement is provided with at least one annular ridge surrounding and spaced from said nozzle section, said ridge adapted to be pressed into the surface oF said perianal area.
Claim 4
Dependent Claim
32 words
The applicator of claim 2, wherein said enlargement is formed integrally with said nozzle section and said stem section peripherally at said junction thereof, and said chamber is formed within said enlargement.
Claim 5
Dependent Claim
53 words
The applicator of claim 3, wherein said posterior extension comprises a horizontal plate and a sagittal flange formed integrally with and depending from the distal surface of said horizontal plate and connected to said tubular stem section to provide proximal leverage for the sealing and immobilizing of said applicator in anal sealing position.
Claim 6
Dependent Claim
36 words
The applicator of claim 3, wherein said chamber within said enlargement is formed with a proximal inlet opening connected to said tubular nozzle section and with an opposite distal opening connected to said tubular stem section.
Claim 7
Dependent Claim
40 words
The applicator of claim 3, wherein said chamber formed within said enlargement comprises at least two compartments, a first of said compartments being centrally located and substantially cylindrical, and a second of said compartments being peripherally located and substantially annular.
Claim 8
Dependent Claim
80 words
The applicator of claim 6, wherein said first compartment extends normally to the axis of said tubular nozzle section and includes a proximal inlet opening connected to said tubular nozzle section, said first compartment having a greater diameter than that of said proximal inlet opening, and an annular depending flange defining the outer periphery and distal extent of said first compartment, said flange having a distal opening formed above and separated from the proximal end of said tubular stem section.
Claim 9
Dependent Claim
36 words
The applicator of claim 6, wherein said chamber includes said first compartment and said second compartment, and further includes a circumferential channel interconnecting said compartments, said channel extending normally to the longitudinal axis of said applicator.
Claim 10
Dependent Claim
69 words
The applicator of claim 6, wherein said circumferential channel is located between the distal opening of said first compartment and the proximal opening of said tubular stem section, said tubular nozzle section and said tubular stem section being separated by said circumferential channel, said second compartment adapted to receive said contrast fluid from said circumferential channel and said tubular stem section to thereby provide opaque marking for said applicator.
