Device for venting and controlling the pressure inside a stoma collection bag
First Claim
1. A vent device configured to adapt to a stoma bag, said vent device comprising an essentially flat housing comprising:
- a base having a face inside the housing and a face outside the housing, said vent device being adapted to be fixed via said outside face to an exposed face of said bag and having an opening communicating with said bag, a cover configured to be removably assembled with said bag and to close said base when said cover and said base are assembled together, a valve which is closed at rest, the valve being formed by a valve member adapted to bear against the inside face of said opening in said base, said valve member being integral with said cover and being integral with resilient means for urging said valve member against said base with a predetermined return force, said resilient means being constituted by at least one resiliently deformable flat extending between said cover and said valve member, said housing being further provided with manual actuator means to place said valve member in a closed or opened position.

18. A collection system including a stoma collection bag and vent device comprising means defining a container for receiving and storing waste running from the stoma of a patient, said container including an opening configured to be put into communication with the stoma when the bag is applied to the body of said patient by means of an adhesive plate or a coupling system, said container further comprising a device for venting and controlling internal pressure, said vent device comprising an essentially flat housing comprising:
- a base having a face inside the housing and a face outside the housing, said vent device being adapted to be fixed via said outside face to an exposed face of said bag and having an opening communicating with said bag, a cover configured to be removably assembled with said bag and to close said base when said cover and said base are assembled together, a valve which is closed at rest, the valve being formed by a valve member adapted to bear against the inside face of said opening in said base, said valve member being integral with said cover and being integral with resilient means for urging said valve member against said base with predetermined return force, said resilient means being constituted by at least one resiliently deformable flat extending between said cover and said valve member, said housing being further provided with manual actuator means to place said valve member in a closed or open position.

19. A vent device configured to adapt to a stoma bag, said vent device comprising an essentially flat housing and comprising:
-
a base having a face inside the housing and a face outside the housing, adapted to be fixed via said outside face to an exposed face of said bag and provided with an opening communicating with said bag; a cover adapted to be removably assembled with said base and to close said base when said cover and said base are assembled together; a valve which is closed at rest which includes a valve member adapted to bear against the inside face of said opening in said base and being integral with resilient means for urging said valve member against said base with a predetermined return force, said valve member being integral with said cover; and said housing further comprising rotational guide means for rotating said cover relative to said base around the axis of said housing between a first position in which the valve is closed and a second position in which the valve is opened.
