Disposable absorber with adapter and lip seal
View Patent ↗An adapter is provided for adapting an absorber container ( 4 ) to a breathing system. A seal ( 405 ) is employed that has sealing surfaces ( 55, 56, 57 ), which extend in a jacket area ( 34 ) of a valve crater ( 15 ), which limits an outer gas channel. The seal ( 405 ) is provided between the absorber container ( 4 ) and the adapter.
1. An adapter for adapting an absorber container to a breathing system, the absorber container comprising a first gas channel, with a jacket surface, and a second gas channel, with a jacket surface, said first gas channel and said second gas channel extending into a connection area between said absorber container and the adapter, the adapter comprising:
an adapter housing cooperating with the absorber container to define the connection area;
seals in the connection area and at said first gas channel and at said second gas channel and extending between said absorber container and said adapter, at least one of said seals comprising plural sealing surfaces extending to said jacket surface of one of said first gas channel and said second gas channel.
2. An adapter in accordance with claim 1 , wherein said first gas channel comprises an inner gas channel and said second gas channel comprises an outer gas channel arranged concentrically to said inner gas channel.
3. An adapter in accordance with claim 2 , wherein said second gas channel has an outer valve crater with an outer jacket surface provided as a sealing surface.
4. An adapter in accordance with claim 1 , wherein in an area of said one of the first and second gas channel jacket surface said at least one of said seals has at least one sealing lip defining one of said sealing surfaces and extending in a ring-shaped pattern around said jacket surface of one of said first and said second gas channel.
5. An adapter in accordance with claim 4 , wherein a plurality of said sealing lips are arranged at spaced locations from one another in an area of said jacket surface of one of said first and second gas channels and are in contact with partial surfaces of said jacket surface of one of said first and said second gas channels.
6. An adapter in accordance with claim 3 , wherein a recessed surface is located below and adjacent to said valve crater of said outer gas channel as another sealing surface.
7. An adapter in accordance with claim 6 , wherein said at least one of said seals has another sealing lip in the area of said recessed surface.
8. An absorber container arrangement for adaptation to a breathing system, the arrangement comprising:
an absorber comprising a first gas channel with a jacket surface and a second gas channel with a jacket surface;
an absorber container to breathing system adapter comprising an adapter housing cooperating with the absorber container to define a connection area, each of said first gas channel and said second gas channel extending into said connection area between said absorber container and said adapter, and a plurality of seals, said seals sealing the connection area in a region of said first gas channel and at said second gas channel and extending between said absorber container and said adapter, at least one of said seals comprising plural sealing surfaces extending to said jacket surface of one of said first gas channel and said second gas channel.
9. An absorber container arrangement in accordance with claim 8 , wherein said first gas channel comprises an inner gas channel and said second gas channel comprises an outer gas channel arranged concentrically to said inner gas channel.
10. An absorber container arrangement in accordance with claim 9 , wherein said second gas channel has an outer valve crater with an outer jacket surface provided as a sealing surface.
11. An absorber container arrangement in accordance with claim 10 , wherein in an area of said outer jacket surface said at least one of said seals has at least one sealing lip defining one of said sealing surfaces and extending in a ring-shaped pattern around said outer jacket surface.
12. An absorber container arrangement in accordance with claim 11 , wherein a plurality of said sealing lips are arranged at spaced locations from one another in an area of said outer jacket surface and are in contact with partial surfaces of said outer jacket surface.
13. An absorber container arrangement in accordance with claim 12 , wherein a recessed surface is located below and adjacent to said valve crater of said outer gas channel as another sealing surface and one of said plurality of said sealing lips is in contact with said recessed surface as another sealing surface.
