An ostomy appliance with a front wall and a rear wall of flexible material forming a bag, the rear wall having an opening into the bag by which waste material can enter the bag. The bag has two or more vents through which gas may escape from the bag and a filter device covering each vent. Each filter device has gas inlet and outlet openings in communication with a respective filter body so that in use gas flows through the filter device from the inlet opening through the filter body to the outlet opening. The inlet openings communicate with the inner space of the bag and are located near the border of the bag, being spaced at an angle of at least 45 degrees along radii of a circle of reference having a perimeter concentric with the waste opening of the bag.

The invention is: 1. An ostomy appliance comprising a front wall and a rear wall of flexible material forming a bag, the rear wall having a waste opening into the bag by which waste material can enter an inner space of the bag, said bag having two or more vents through which gas may escape from the bag, each vent being covered by a separate filter device, each filter device being provided with a respective gas inlet opening in communication with the inner space of the bag and a respective filter body, and a respective outlet opening in communication with said filter body and a respective one of said vents so that in use gas flows through the filter device from the inlet opening through the filter body to the outlet opening, such gas flow being confined to said filter body, said two separate filter devices being provided in one of said walls and the respective inlet openings of said two filter devices being located at opposite sides of a vertical center line of said bag, less than three centimeters from a border of the bag and spaced from one another at an angle of at least about 45 degrees along radii of a circle of reference having a perimeter concentric with the waste opening of the bag. 2. The ostomy appliance as claimed in claim 1, wherein the filter devices have border lines being a part of a circle. 3. The ostomy appliance as claimed in claim 2, wherein at least a part of a top of the bag where the filters are secured has a border line that is part of a circle having the same diameter as that of the filter devices. 4. The ostomy appliance as claimed in claim 2, wherein a top of the bag has a border line that is a part of a circle having the same diameter as that of the filter devices. 5. The ostomy appliance as claimed in claim 2, wherein the separate filter devices are located end to end at a top of the bag. 6. An ostomy appliance comprising a front wall and a rear wall of flexible material forming a bag, the rear wall having a waste opening into the bag by which waste material can enter an inner space of the bag, said bag having two or more vents through which gas may escape from the bag, each vent being covered by a separate filter device, each filter device being provided with a respective gas inlet opening in communication with the inner space of the bag and a respective filter body, and a respective outlet opening in communication with said filter body and a respective one of said vents so that in use gas flows through the filter device from the inlet opening through the filter body to the outlet opening, such gas flow being confined to said filter body, each of the walls of the ostomy appliance being provided with at least one vent and a separate associated filter device, the inlet openings of said associated filter devices being located at opposite sides of a vertical center line of said bag, less than three centimeters from a border of the bag and spaced from one another at an angle of at least about 45 degrees along radii of a circle of reference having a perimeter concentric with the waste opening of the bag. 7. An ostomy appliance comprising a front wall and a rear wall of flexible material forming a bag, the rear wall having a waste opening into the bag by which waste material can enter an inner space of the bag, said bag having at least a first vent and a second vent through which gas may escape from the bag, a first filter device covering said first vent and a second filter device covering said second vent, said first and second filter devices being independent from one another, said first filter device being provided with a first gas inlet opening, a first filter body and a first gas outlet opening, said first gas inlet opening being in communication with the inner space of the bag and said first filter body, and said first outlet opening being in communication with said first filter body and said first vent so that in use gas flows from the inner space of the bag, through the first inlet opening through the first filter body to the first outlet opening and out the first vent, said second filter device being provided with a second gas inlet opening, a second filter body and a second gas outlet opening, said second gas inlet opening being in communication with the inner space of the bag and said second filter body, and said second outlet opening being in communication with said second filter body and said second vent so that in use gas flows from the inner space of the bag, through the second inlet opening through the second filter body to the second outlet opening and out the second vent, said first and second inlet openings of the filter devices being located at opposite sides of a vertical center line of said bag, less than three centimeters from a border of the bag and spaced from one another at an angle of at least about 45 degrees along radii of a circle of reference having a perimeter concentric with the waste opening of the bag. 8. The ostomy appliance as set forth in claim 7, wherein said first and second vents are both in one of said walls. 9. The ostomy appliance as set forth in claim 7, wherein said first vent is in said front wall and said second vent is in said rear wall. 10. The ostomy appliance as claimed in claim 7, wherein the first and second filter devices are located end to end at a top of the bag. 11. The ostomy appliance as claimed in claim 7, wherein the filter devices have border lines being a part of a circle. 12. The ostomy appliance as claimed in claim 11, wherein at least a part of a top of the bag where the filters are secured has a border line that is part of a circle having the same diameter as that of the filter devices. 13. The ostomy appliance as claimed in claim 11, wherein a top of the bag has a border line that is a part of a circle having the same diameter as that of the filter devices. 14. The ostomy appliance as claimed in claim 11, wherein the separate filter devices are located end to end at a top of the bag. 15. The ostomy appliance as claimed in claim 6, wherein the first and second filter devices are spaced from one another so that, although on separate walls, they are located end to end at a top of the bag. 16. The ostomy appliance as claimed in claim 6, wherein the filter devices have border lines being a part of a circle. 17. The ostomy appliance as claimed in claim 16, wherein at least a part of a top of the bag where the filters are secured has a border line that is part of a circle having the same diameter as that of the filter devices. 18. The ostomy appliance as claimed in claim 16, wherein a top of the bag has a border line that is a part of a circle having the same diameter as that of the filter devices.
