Abstract: An ostomy bag device includes a bag with first and second chambers communicating via a first opening and a pressure sensitive interface. The bag includes a second opening interfacing with a stoma exit and receiving waste in the first chamber, a third opening expelling the waste from the first chamber, and a fourth opening releasing gas from the second chamber. The interface transitions from a first state in which the interface prevents a gas flow through the first opening from the first to second chambers and a second state in which the interface allows the flow. A first pressure differential in the first chamber relative to the second chamber causes the interface to assume the first state preventing the flow and a second pressure differential in the first chamber relative to the second chamber higher than the first differential causes the interface to assume the second state allowing the flow.
