Abstract
An ostomy appliance includes a sound absorbing film comprising a triblock copolymer including polystyrene blocks and vinyl-bond rich rubber mid-block, and a sound absorbing non-woven material comprising the triblock copolymer including polystyrene blocks and vinyl-bond rich rubber mid-block. The ostomy appliance has improved sound absorbing properties to insulate flatulence noise.
Claims28
A sound insulating ostomy pouch, comprising:
- a first wall,
- a second wall, wherein the first wall and the second wall are sealed along their peripheral edges to define a cavity;
- and
- at least one sound absorbing non-woven layer including fibers formed from a polymer blend comprising a vinyl-bond rich triblock copolymer, wherein the at least one sound absorbing non-woven layer is attached to the first wall.
A sound absorbing non-woven material for ostomy appliances, comprising fibers including a non-hydrogenated vinyl-bond rich SIS block copolymer.
A sound absorbing non-woven material for ostomy appliances, comprising fibers are formed from a polymer blend comprising a hydrogenated vinyl-bond rich styrene-isoprene-styrene block copolymer.
A sound absorbing film for ostomy appliances, comprising at least one layer comprising at least 50% wt. of a non-hydrogenated vinyl-bond rich SIS block copolymer.
A sound absorbing multilayer film for ostomy appliances, comprising at least one layer comprising a hydrogenated vinyl-bond rich SIS block copolymer.
