Abstract
A more comfortable ostomy bag that will not irritate the skin from relative movement. The ostomy bag has a pair of flexible flat sheets of material bonded together at juxtaposed edges to form a seam. A soft outer edge outside of the seam is formed by extensions of the sheets that either remain disconnected so as to form loose flaps or are slit radially to form finger-like extensions, or both. The ostomy bag further has an inlet opening formed through one of the flat sheets.
Core Innovation
An ostomy bag is provided with a pouch formed by a pair of flexible flat sheets of liquid impermeable material bonded together at juxtaposed edges at a peripheral seam to define an inner cavity. A soft outer edge is formed radially outward of the seam by disconnected outward extensions of the sheets that form loose flaps. The ostomy bag further includes an inlet opening and a stoma seal formed through one of the flat sheets and open to the inner cavity.
The pouch is defined with a long dimension and a short dimension perpendicular to the long dimension, and the soft outer edge has a radial dimension between 5-15% of the short dimension. The soft outer edge can be configured such that the disconnected outward extensions include scalloped configurations with varying radial dimensions around the outer edge, or can include slit radially to form finger-like projections.
The disclosure also includes configurations in which the outward extensions are continuous or scalloped with varying radial dimensions, and in which the finger-like projections form rectangular fingers with rounded outer ends. An outlet may be provided at one end that interrupts the peripheral seam, including variations where features near the outlet interrupt or modify the peripheral seam continuity.
Claims Coverage
The independent claims (1, 11, and 12) cover an ostomy bag formed from two flexible liquid impermeable flat sheets bonded at a peripheral seam, with a soft outer edge made from disconnected outward extensions (loose flaps), and an inlet opening with a stoma seal through one sheet. Across the independents, three main inventive feature groupings are used: a quantitative radial dimension ratio for the soft outer edge, scalloped configurations with varying radial dimensions, and slit finger-like projections forming the soft outer edge.
Loose flaps soft outer edge from disconnected outward extensions with defined radial dimension ratio
An ostomy bag with a pouch formed by bonded flexible flat sheets of liquid impermeable material at a peripheral seam, and a soft outer edge radially outward of the seam formed by disconnected outward extensions that form loose flaps; an inlet opening and a stoma seal formed through one of the flat sheets and open to the inner cavity; wherein the pouch has a long dimension and a short dimension perpendicular to the long dimension; and wherein the soft outer edge has a radial dimension of between 5-15% of the short dimension.
Scalloped configurations with varying radial dimensions for loose flap outer extensions
An ostomy bag with a pouch formed by bonded flexible flat sheets of liquid impermeable material at a peripheral seam, and a soft outer edge radially outward of the seam formed by disconnected outward extensions that form loose flaps; an inlet opening and a stoma seal formed through one of the flat sheets and open to the inner cavity; wherein the outward extensions have scalloped configurations with varying radial dimensions around the outer edge.
Soft outer edge formed by slitted sheet extensions producing finger-like projections
An ostomy bag with a pouch formed by bonded flexible flat sheets of liquid impermeable material at a peripheral seam, and a soft outer edge radially outward of the seam formed by outward extensions of the sheets that are slit radially to form finger-like projections; an inlet opening and a stoma seal formed through one of the flat sheets and open to the inner cavity.
Across claims 1, 11, and 12, the core claim coverage requires two flexible liquid impermeable sheets forming a pouch with an inlet opening and stoma seal through one sheet, together with a soft outer edge created by disconnected outward extensions. The independents further distinguish the outer-edge geometry by (i) applying a 5-15% radial dimension ratio, (ii) requiring scalloped configurations with varying radial dimensions, or (iii) requiring radially slit outward extensions that form finger-like projections.
