Abstract

A facial respiratory interface (1, 11) comprising an interface body (2, 12) which bears at least one thermistor (3) having an active end (4) which can be placed opposite the mouth of a user when the interface (1, 11) is put into position on the facial region of said user, wherein the length (L) separating the active end (4) from the interface body (2, 12) can be adjusted. The interface can be used for treating respiratory disorders in a patient, in particular sleep apnea.

Claims

1. A facial respiratory interface (1, 11) comprising an interface body (2, 12) which bears at least one thermistor (3) having an active end (4) which can be placed opposite the mouth of a user when the interface (1, 11) is put into position on the facial region of said user, wherein the length (L) separating the active end (4) from the interface body (2, 12) can be adjusted.

2. The interface as claimed in claim 1, wherein said active end (4) is moved away from the interface body (2, 12) by exerting a traction on said end in such a way as to increase the length (L).

3. The interface as claimed in either of claims 1 and 2, wherein the interface body (2, 12) comprises a support (5) bearing said thermistor (3).

4. The interface as claimed in one of claims 1 through 3, wherein the support (5) comprises a hollow elongate part within which the thermistor can slide, preferably a tubular part.

5. The interface as claimed in either of claims 3 and 4, wherein the elongate and hollow support part comprises a longitudinal slit (6).

6. The interface as claimed in one of claims 3 through 5, wherein the elongate and hollow support part comprises an extension (5) forming a T.

7. The interface as claimed in one of claims 1 through 6, wherein the interface is chosen from the group consisting of breathing masks and breathing clips.

8. The interface as claimed in one of claims 1 through 7, wherein it is connected via a gas channel to an apparatus for artificial ventilation.

9. A respiratory apparatus which can be used to treat or diagnose respiratory disorders of sleep in a person, comprising a facial respiratory interface (1, 11) as claimed in one of claims 1 through 8, said interface preferably being connected to said apparatus by way of one or more gas channels.

10. The apparatus as claimed in claim 9, being of the type with one or two pressure levels.
