Abstract
A device (FV) for filtering breathing gas has a housing (G) with a gas inlet (GE), a gas outlet (GA) and a filter (F), which is arranged in a first housing section (G1) formed between the gas inlet (GE) and the gas outlet (GA). The housing (G) has a second housing section (G2) gas-tightly separated from the first housing section (G1) with at least one first wall (W1, W2, W3), which establishes a thermal contact with a wall (W1, W2, W3) of the first housing section (G1). The second housing section (G2) has an opening on an outer side of the housing (G).
Claims13
A device for filtering breathing gas, the device comprising:
- a housing with a gas inlet and a gas outlet and having a first housing section formed between said gas inlet and said gas outlet, said first housing section having a first housing section wall surface and having a second housing section gas-tightly separated from said first housing section, said second housing section having a second housing section wall surface in thermal contact with said first housing section wall surface, said second housing section having an opening on an outer side of said housing;
- and
- a filter arranged in said first housing section.
A respiration system comprising:
- a device for providing breathing gas, which device has an outer wall;
- a filtering device comprising a housing with a gas inlet and a gas outlet and having a first housing section formed between said gas inlet and said gas outlet, said first housing section having a first housing section wall surface and a second housing section gas-tightly separated from said first housing section, said second housing section having a second housing section wall surface in thermal contact with said first housing section wall surface, said second housing section having an opening from an interior of said second housing section to an outer side of said housing and a filter arranged in said first housing section, wherein at least one outer wall of said second housing section is arranged adjacent to said outer wall of said device for providing breathing gas, which said outer wall of said device for providing breathing gas is formed in a recess, such that air flowing past in the recess at said outer wall of said device for providing breathing gas also flows along said at least one outer wall of said second housing section.
A respiration system comprising:
- a housing comprising a first housing section defining a breathing gas flow passage with a gas inlet and a gas outlet, and a second housing section defining a fluid space with an opening connecting said fluid space to outside of said housing, said first housing section being gas-tightly separated from said second housing section, said second housing section being in thermal contact with said first housing section for heat transfer from said fluid space to said gas flow passage;
- and
- a filter arranged in said first housing section.
