US3878847A — Membrane stoma seal for ostomy patients

Claim 1

Independent Claim 119 words

A membrane for use as a stoma seal for a pouch in ostomy conditions, the membrane comprising a sheet of extremely thin material having a high degree of elasticity and a thinness functioning as of approximately about one thousanth of an inch to ten thousanths of an inch throughout its area, a means for embracing and sealing the stoma comprising an opening in its center for receiving the stoma, said opening being smaller in diameter than the diameter of the stoma to which the membrane is to be applied and defining a band-like means around the stoma when applied thereto so that the membrane maintains a seal with the outer circumference of the stoma wall completely around the stoma.

Claim 2

Dependent Claim 119 words

A membrane for use as a stoma seal for a pouch in ostomy conditions, the membrane comprising a sheet of extremely thin material having a high degree of elasticity and a thinness functioning as of approximately about one thousanth of an inch to ten thousanths of an inch throughout its area, a means for embracing and sealing the stoma comprising an opening in its center for receiving the stoma, said opening being smaller in diameter than the diameter of the stoma to which the membrane is to be applied and defining a band-like means around the stoma when applied thereto so that the membrane maintains a seal with the outer circumference of the stoma wall completely around the stoma.

Claim 3

Dependent Claim 119 words

A membrane for use as a stoma seal for a pouch in ostomy conditions, the membrane comprising a sheet of extremely thin material having a high degree of elasticity and a thinness functioning as of approximately about one thousanth of an inch to ten thousanths of an inch throughout its area, a means for embracing and sealing the stoma comprising an opening in its center for receiving the stoma, said opening being smaller in diameter than the diameter of the stoma to which the membrane is to be applied and defining a band-like means around the stoma when applied thereto so that the membrane maintains a seal with the outer circumference of the stoma wall completely around the stoma.

Claim 4

Dependent Claim 119 words

A membrane for use as a stoma seal for a pouch in ostomy conditions, the membrane comprising a sheet of extremely thin material having a high degree of elasticity and a thinness functioning as of approximately about one thousanth of an inch to ten thousanths of an inch throughout its area, a means for embracing and sealing the stoma comprising an opening in its center for receiving the stoma, said opening being smaller in diameter than the diameter of the stoma to which the membrane is to be applied and defining a band-like means around the stoma when applied thereto so that the membrane maintains a seal with the outer circumference of the stoma wall completely around the stoma.

Claim 5

Dependent Claim 26 words

For use in colostomy conditions, the subject matter set forth in claim 1, in which the membrane includes the ingredients vinyl chloride QYKV-2 and dioctyl phatalate.

Claim 6

Dependent Claim 47 words

For use in colostomy conditions, the subject matter set forth in claim 1, in which the membrane includes the ingredients silastic E RTV a silicone rubber compound supplied by Dow Corning Corporation, Midland, Michigan, one gram of silastic E RTV catalyst, and one gram silastic RTV thinner.

Claim 7

Dependent Claim 114 words

For use with a body fluid receiving means in colostomy conditions, a membrane for application to the patient''s the stoma, the throughout its area being of a thinness approximating one thousanth of an inch to ten thousanths of an inch, the membrane being of waterproof material that is soft, flexible, and very elastic, the membrane having in its center an opening smaller in diameter than the diameter of the stoma so that the central area of the membrane will stretch to provide a band-like contact seal means around the stoma when applied thereto and maintain sealing engagement with the circumference of the stoma in a substantial area completely around the wall of the stoma.

Claim 8

Dependent Claim 114 words

For use with a body fluid receiving means in colostomy conditions, a membrane for application to the patient''s the stoma, the throughout its area being of a thinness approximating one thousanth of an inch to ten thousanths of an inch, the membrane being of waterproof material that is soft, flexible, and very elastic, the membrane having in its center an opening smaller in diameter than the diameter of the stoma so that the central area of the membrane will stretch to provide a band-like contact seal means around the stoma when applied thereto and maintain sealing engagement with the circumference of the stoma in a substantial area completely around the wall of the stoma.

Claim 9

Dependent Claim 83 words

For use in colostomy conditions, a membrane as set forth in claim 4, and means for applying the membrane to a patient in a manner to provide a membrane area peripherally around said central area serving by its extreme thinness and elasticity to allow relative movements between said applying means and the stoma seal at the central area of the stoma, thereby providing a leak-proof stoma seal without strangulating or injuring the stoma and its seal under the varying conditions incident to use.

Claim 10

Dependent Claim 26 words

A membrane stoma seal as set forth in claim 1, in combination with means providing for leak-proof attachment of the membrane circumferentially thereof to a pouch.

Claim 11

Dependent Claim 73 words

A membrane stoma seal as set forth in claim 1, in combination with means providing a substantially rigid support for the membrane circumferentially thereof, and means for attaching said support to a pouch with the stoma extending into the pouch, whereby normal strains on the pouch when it is worn on a patient will not be transferred beyond said support in a manner to disturb the seal of the membrane with the stoma.

Claim 12

Dependent Claim 29 words

A membrane stoma seal as set forth in claim 1, in combination with means to isolate the membrane seal from external stresses when it is worn on a patient.

Claim 13

Dependent Claim 52 words

A membrane stoma seal as set forth in claim 1, in combination with a pouch and means for supporting the membrane in co-active relation with the pouch and with the membrane positioned so that the seal will only be subjected to the stress applied by inserting the stoma into the membrane opening.

Claim 14

Dependent Claim 30 words

For use in ostomy conditions, a membrane as set forth in claim 1, the membrane having a circumferential strengthening rim of the same material as the membrane and integral therewith.
