STOMA ADAPTER
First Claim
1. An apparatus for use in conjunction with a catheter having a conduit to extend into a stoma in a person'"'"''"'"'s body wall and having an enlargement surrounding the conduit and being larger than the stoma to contact the body wall with a portion of the conduit extending outwardly from said enlargement, said apparatus comprising:
- a base having two ends and walls between said two ends, said walls defining a truncated conical internal opening relatively large at one end and relatively small at the other, said large end being of a size to receive said enlargement, said base having an outward peripheral flange at said one end of said walls of a configuration to fit flat against said body wall about said stoma, said base having an opening at said other end to receive said portion of the conduit, whereby when said catheter is so positioned on said person'"'"''"'"'s body wall said base may be placed over the catheter with the enlargement within the large end of the internal opening and said portion extending through said end opening, said internal opening being of a size that said base walls will, when said catheter and base are so positioned, bear against the periphery of said enlargement to hold said enlargement against said stoma, and means for holding said base with its flange firmly against the person'"'"''"'"'s body and including a body-encircling band and a part in contact with the exterior of the base.

Abstract
A device for conveying fluids, such as aqueous suspensions of barium sulfate, into and out of a body opening such as a colostomy opening, including conduit means, a radial flange integral with the conduit means, pressure means for maintaining the flange in direct contact with a stoma, base means for engaging the abdominal wall, said base means being constructed to abut the abdominal wall closely adjacent the stoma, bodyencircling means for maintaining the base means in place, said pressure means being fixed with respect to said base means, whereby the body cavity is sealed at the stoma and fluid communication between the cavity and the exterior abdominal wall is prevented.

1. An apparatus for use in conjunction with a catheter having a conduit to extend into a stoma in a person'"'"''"'"'s body wall and having an enlargement surrounding the conduit and being larger than the stoma to contact the body wall with a portion of the conduit extending outwardly from said enlargement, said apparatus comprising:
- a base having two ends and walls between said two ends, said walls defining a truncated conical internal opening relatively large at one end and relatively small at the other, said large end being of a size to receive said enlargement, said base having an outward peripheral flange at said one end of said walls of a configuration to fit flat against said body wall about said stoma, said base having an opening at said other end to receive said portion of the conduit, whereby when said catheter is so positioned on said person'"'"''"'"'s body wall said base may be placed over the catheter with the enlargement within the large end of the internal opening and said portion extending through said end opening, said internal opening being of a size that said base walls will, when said catheter and base are so positioned, bear against the periphery of said enlargement to hold said enlargement against said stoma, and means for holding said base with its flange firmly against the person'"'"''"'"'s body and including a body-encircling band and a part in contact with the exterior of the base.
-
2. An apparatus as set forth in claim 1, wherein the exterior of said base defines a step of annular configuration between said ends and substantially parallel to said ends, and said part comprises a plate having an opening therein of a size to be received only over the portion of said base between said step and said other end.
-
3. An apparatus as set forth in claim 2, wherein there are a plurality of said steps with each step, commencing from said other end, being a larger annulus from that of the preceding step, whereby a plurality of said parts having openings therein of different sizes, may be interchanged one at a time to engage a respective sized step.
-
4. In the combination of a catheter and a device to hold it in place wherein the catheter has a conduit to extend into a stoma in a person'"'"''"'"'s body wall and having an enlargement surrounding the conduit and being larger than the stoma to contact the body wall with a portion of the conduit extending outwardly from said enlargement, the improvement wherein said device comprises:
- a base having two ends and walls between said two ends, said walls defining a truncated conical internal opening relatively large at one end and relatively small at the other, said large end receiving said enlargement, said base having an outward peripheral flange at said one end of said walls of a configuration to fit flat against said body wall about said stoma, said base having an opening at said other end receiving said portion of the conduit, said internal opening being of a size that said base walls will, when said catheter and base are so positioned, bear against the periphery of said enlargement to hold said enlargement against said stoma, and means for holding said base wiTh its flange firmly against the person'"'"''"'"'s body and including a body encircling band and a part in contact with the exterior of the base.
-
5. In the combination as set forth in claim 4, wherein the enlargement comprises a pneumatically expandable bulb.
-
6. In the combination as set forth in claim 5, wherein the exterior of said base defines a step of annular configuration between said ends and substantially parallel to said ends, and said part comprises a plate having an opening therein of a size to be received only over the portion of said base between said step and said other end.
-
7. In the combination as set forth in claim 6, wherein there are a plurality of said steps with each step commencing from said other end, being a larger annulus from that of the preceding step, whereby a plurality of said parts having openings therein of different sizes may be interchanged one at a time to engage a respective sized step.
-
8. In the combination as set forth in claim 4, wherein the exterior of said base defines a step of annular configuration between said ends and substantially parallel to said ends, and said part comprises a plate having an opening therein of a size to be received only over the portion of said base between said step and said other end.
-
9. In the combination as set forth in claim 8, wherein there are a plurality of said steps with each step commencing from said other end, being a larger annulus from that of the preceding step, whereby a plurality of said parts having openings therein of different sizes may be interchanged one at a time to engage a respective sized step.
