Abstract

A breathing mask arrangement for delivering breathable gas to a patient includes a frame having an open construction that provides an annular mask retaining portion, a nasal mask having a body portion structured to be removably attachable within 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 conduit member in fluid communication with the nasal mask to deliver breathable gas into a nasal breathing space of the nasal mask, and a hose connector coupled to the conduit member. The hose connector is structured to be connected to a gas delivery tube.

Claims

1-44. -44. (canceled)

45. A breathing mask arrangement for delivering breathable gas to a patient, comprising:

a frame having an open construction that provides an annular mask retaining portion;

a nasal mask having a body portion structured to be removably attachable within 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 conduit member in fluid communication with the nasal mask to deliver breathable gas into a nasal breathing space of the nasal mask; and

a hose connector coupled to the conduit member, the hose connector structured to be connected to a gas delivery tube.

46. The breathing mask arrangement according to claim 45, wherein the body portion of the nasal mask includes a groove to receive the open frame.

47. The breathing mask arrangement according to claim 45, wherein the body portion of the nasal mask includes a first side including said sealing portion and a second side defining a mask interior breathing chamber, the first and second sides being provided on opposite sides of the open frame.

48. 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 and a sealing portion integrally formed in one piece, the body portion defining a mask interior breathing chamber structured to accommodate the patient'"'"'s nose and being removably attachable to the mask retaining portion of the frame, and the sealing portion structured to engage a patient'"'"'s face generally along nasal bridge, cheek, and lip regions of the patient'"'"'s face;

a conduit member in fluid communication with the nasal mask to deliver breathable gas into a nasal breathing space of the nasal mask; and

a hose connector coupled to the conduit member, the hose connector structured to be connected to a gas delivery tube.

49. The breathing mask arrangement according to claim 48, further comprising a forehead support supporting elastomeric forehead padding that is structured to engage a patient'"'"'s forehead, the forehead support being moveably coupled to the frame to allow movement of the forehead support relative to the frame along an arcuate path to thereby adjust the position of the forehead padding relative to the patient.

50. The breathing mask arrangement according to claim 49, wherein the forehead padding of the forehead support is integrally formed in one piece along with the body portion and sealing portion of the nasal mask.
