Abstract
Abstract A breathing device for tracheotomy patients, comprising a holder (12) detachably connected to the outer end of a tracheal cannula (11) or to a stoma in the patient's throat, the holder holding detachably a regenerative heat-moisture exchanger (14). The holder (12) is an air-proof receptacle having a first opening (12a) communicating with the outer end (11b) of the tracheal cannula (11) or with the stoma in the throat and a second opening (12b) situated opposite the first opening. The heat-moisture exchanger (14), which is provided with a filter body (16), sealingly engages with the edges of the second opening.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
120 words
1 A breathing device for tracheotomy patients, comprising a holder detachably connected to an outer end of a tracheal cannula terminating at the throat of the patient or to a stoma in the patient's throat, the holder holding a regenerative heat-moisture exchanger, characterized in that the holder (2; 12; 22) is an air-proof receptacle having a first opening (2a; 12a; 22a) communicating with the outer end (1a; 11b) of the tracheal cannula (1; 11) or with the stoma in the throat and a second opening (2b; 12b; 22b) situated opposite the first opening, the heat-moisture exchanger (4; 14; 24) , which is provided with a filter body (6; 16), sealingly and detachably engaging with the edges of the second opening.
Claim 2
Dependent Claim
120 words
1 A breathing device for tracheotomy patients, comprising a holder detachably connected to an outer end of a tracheal cannula terminating at the throat of the patient or to a stoma in the patient's throat, the holder holding a regenerative heat-moisture exchanger, characterized in that the holder (2; 12; 22) is an air-proof receptacle having a first opening (2a; 12a; 22a) communicating with the outer end (1a; 11b) of the tracheal cannula (1; 11) or with the stoma in the throat and a second opening (2b; 12b; 22b) situated opposite the first opening, the heat-moisture exchanger (4; 14; 24) , which is provided with a filter body (6; 16), sealingly and detachably engaging with the edges of the second opening.
