Breathing mask for feeding a breathing gas to a mask user and discharge device for discharging breathing gas
First Claim
1. A breathing mask arrangement for delivering breathable gas to a patient, comprising:
- a frame having a mask retaining portion;
a nasal mask having a body portion structured to be removably attachable to the mask retaining portion of the frame and a sealing portion structured to engage a patient'"'"'s face generally along nasal bridge, cheek, and lip regions of the patient'"'"'s face;
a T-shaped forehead support having an upper cross portion and a lower leg portion, the upper cross portion of the forehead support extending along a first axis and supporting elastomeric forehead padding that is structured to engage a patient'"'"'s forehead, the lower leg portion of the forehead support moveably coupled to the frame via a film hinge to allow movement of the forehead support relative to the frame about a second axis that is parallel to the first axis to thereby adjust the position of the forehead padding relative to the patient along an arcuate path;
a conduit member in fluid communication with the nasal mask to deliver breathable gas into a nasal breathing space of the nasal mask;
a hose connector coupled to the conduit member, the hose connector structured to be connected to a gas delivery tube; and
an adjustment arrangement including at least four recesses and a projection, the recesses being adapted to receive the projection to positively lock the forehead support relative to the frame to allow selective adjustment of the forehead support relative to the frame,wherein the forehead support supports the forehead padding at an elevated position with respect to the film hinge when the forehead support is positively locked relative to the frame.

Abstract
The invention relates to a breathing mask for feeding a breathing gas to a mask user and a discharging device for discharging breathing gas from an inner mask area defined by a breathing mask. The inventive breathing mask comprises a sealing lip device for sealing a mask bearing area, a mask base body for creating a space within the mask and a connecting device for connecting at least one breathing gas line, the mask base body and/or the connecting device being provided with at least one decoupling structure made of elastomer material. It is possible to obtain in an advantageous manner a relative movement between a peripheral base area on the side of the base body of the mask associated with the sealing lip device and the breathing gas line within a sufficient area of movement.
