Abstract

Claims50
A method of controlled gas release from an ostomy port having a deployable waste collection bag, comprising:
- determining that there is a need to release gas from a body of a patient;
- and
- releasing said gas from said body to an outside thereof through a gas release pathway that starts inside said body and passes through a gas release mechanism comprising at least one dedicated exhaust lumen configured to be selectively opened, while said waste collection bag remains undeployed, by opening said dedicated exhaust lumen;
- wherein said gas release pathway does not enter the interior of said waste collection bag, when deployed and when undeployed.
1 more element
An ostomy port providing control of gas release, comprising:
- a waste conduction channel terminating at a waste collection bag;
- and
- a gas release mechanism comprising at least one dedicated exhaust lumen and adapted to release gas passing from a body of a patient through a portion of said waste conduction channel and out through said dedicated exhaust lumen without said gas entering said waste collection bag, when deployed and when undeployed;
- wherein:
- said gas release mechanism is configured to be selectively open.
2 more elements
A method of controlled gas release, from an ostomy port having a deployable waste collection bag, comprising:
- providing a gas release pathway comprising a closed gas release mechanism comprising at least one dedicated exhaust lumen, wherein said dedicated exhaust lumen is configured to release gas through said port from a body of a patient when said lumen is open,
- opening said dedicated exhaust lumen from said body to an outside thereof while said waste collection bag remains undeployed;
- wherein said gas pathway passes through said dedicated exhaust lumen and does not enter the interior of said waste collection bag, when deployed and when undeployed.
