Mouthpiece
First Claim
1. An apparatus for supplying breathing gases from a gases supply to a user through a breathing circuit to provide an elevated internal pressure in the user'"'"'s airways, the apparatus comprising:
- a first portion configured to contact the user at a first location, the first portion defining an opening configured to allow breathing gases to pass from the breathing circuit to the user;
a second portion configured to contact the user at a second location;
an adjustment mechanism that moves the second portion in a linear manner relative to the first portion along an adjustment axis that extends in a fore and aft direction relative to the user such that the apparatus can be adjusted to the user'"'"'s facial contours, wherein the adjustment mechanism comprises;
an adjuster rotatably clipped to the first portion for rotation relative to the first portion in a fixed axial position relative to the first portion, the adjuster comprising a first thread element;
a second thread element provided on the second portion, wherein the first thread element and the second thread element engage one another such that relative rotation of the first thread element and the second thread element causes the movement of the second portion relative to the first portion along the adjustment axis;
a linear slot on the second portion, wherein the linear slot extends in an axial direction and interrupts threads of the second thread element, and wherein spaces between the threads of the second thread element open to each side of the slot such that threads of the first thread element can move across the slot;
wherein, when the adjuster is rotated, the adjuster causes rotation of the first thread element with respect to the second thread element; and
an elbow connector configured to connect the apparatus with the breathing circuit.

Abstract
A mouthpiece having a vestibular shield overlapping a user'"'"'s teeth and gums, a gases passageway extending through the vestibular shield allowing for the passage of the gases through the mouthpiece and an extra oral sealing member is associated with the gases passageway. The passageway in use causes gases to be diffused when exiting from the gases passageway. The mouthpiece may have a noseflap to seal the user'"'"'s nose or provide a passageway for the user'"'"'s nasal passages. The mouthpiece may have an adjustment arrangement to alter a distance between the vestibular shield and the extra-oral sealing member.

11. A user interface for supplying breathing gases from a gases supply to a user through a breathing circuit to provide an elevated internal pressure in the user'"'"'s airways, the user interface comprising:
-
a first interface portion, the first interface portion defining an opening configured to allow breathing gases to pass from the breathing circuit to the user; a second interface portion; an adjustment mechanism configured to provide translation of the second interface portion relative to the first interface portion such that the apparatus can be adjusted to the user'"'"'s facial contours, wherein the adjustment mechanism comprises a rotational threaded connection between the first interface portion and the second interface portion, and wherein the adjustment mechanism further comprises a rotational adjuster configured to permit a user to operate the adjustment mechanism, wherein the second interface portion extends through the first interface portion to engage the rotational adjuster, wherein the threaded connection comprises a first thread element engaged with a second thread element, further comprising a linear slot on the second interface portion, wherein the linear slot extends in an axial direction and interrupts threads in the second thread element, wherein spaces between the threads of the second thread element open to each side of the slot such that threads of the first thread element can move across the slot; a conduit connector configured to connect the user interface with the breathing circuit. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
