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: 13
Claim 1
Independent Claim
168 words
A breathing device for tracheostomy patients, comprising: (a) a holder to be detachably connected to an outer end of a trachea cannula terminating at the throat of the patient or to a stoma in the patient's throat, (b) a regenerative heat-moisture exchanger including a filter body and held by said holder, (c) said holder being formed as an air-proof receptacle having (d) (1) a first opening communicating with the outer end of the tracheal cannula or with the stoma in the throat, and (d) (2) a second opening situated opposite the first opening, (e) the heat-moisture exchanger sealingly and detachably engaging with the edges of said second opening, and (f) said first and second holder openings being substantially axially aligned wherein the filter body is cylindrical, having passageways for breathing air flowing towards and from the filter body substantially in parallel with a connecting line between the two openings, the distance between the openings being smaller than the extension of the filter body perpendicular to said connecting line.
Claim 2
Dependent Claim
168 words
A breathing device for tracheostomy patients, comprising: (a) a holder to be detachably connected to an outer end of a trachea cannula terminating at the throat of the patient or to a stoma in the patient's throat, (b) a regenerative heat-moisture exchanger including a filter body and held by said holder, (c) said holder being formed as an air-proof receptacle having (d) (1) a first opening communicating with the outer end of the tracheal cannula or with the stoma in the throat, and (d) (2) a second opening situated opposite the first opening, (e) the heat-moisture exchanger sealingly and detachably engaging with the edges of said second opening, and (f) said first and second holder openings being substantially axially aligned wherein the filter body is cylindrical, having passageways for breathing air flowing towards and from the filter body substantially in parallel with a connecting line between the two openings, the distance between the openings being smaller than the extension of the filter body perpendicular to said connecting line.
