Abstract
Abstract The present invention discloses an improvement in an ostomy bag which permits undesirable gases to escape only after passing through a separate deodorant filled chamber. The chamber is located at the top of the bag and an interconnecting tube provides for the passage of the gases from the bag to the deodorant chamber. A similar tube connected to the deodorant chamber allows the deodorized gases to pass into the atmosphere. A single use or renewable use design is disclosed.
