Abstract
A frame assembly for a ventilator to deliver gas includes: a frame with a first interface set on the patient's forehead, a second interface near a nasal side of the patient, and a hollow tube; wing elements, to connect to a headgear to secure the frame on the patient's face, having a first wing element and a second wing element. The hollow tube extends from the patient's first nasal side, ascends towards the first temporal region, further rises to the forehead, then extends to the second temporal region and reaches the second nasal side, to form a contour that at least partially encircles the patient's eyes and nose. A support portion, set on an inner wall of the hollow tube, is to prevent the gas delivery device from bottoming out.

A frame assembly for a ventilator to deliver gas, configured to deliver positive pressure breathing gas from a flow generator to an airway of a patient for treatment of sleep breathing disorders, the frame assembly for the ventilator to deliver gas comprising:
- a frame comprising:
- a first interface configured to be provided on a forehead of the patient to receive positive pressure breathing gas,
- two second interfaces configured to be provided on, respectively, a first nasal side and a second nasal side of the patient, and
- a symmetrical hollow tube configured to be connected to the first interface positioned at a center of the frame and to the two second interfaces on both the first and the second nasal sides of the patient, the symmetrical hollow tube configured to deliver positive pressure breathing gas from the first interface to the two second interfaces, the hollow tube comprising:
- a front wall,
- a back wall,
- an inner edge, and
- an outer edge formed at a junction of the front wall and the back wall;
- wing elements, integrally formed with the frame and made of silicone with a hardness of at or between 30 A to 70 A on a Shore scale, configured to connect a headgear to secure the frame on a face of the patient, the wing elements are configured to extend towards an area above ears of the patient,
- wherein the wing elements have a force applied to the frame that is configured to extend towards a back part of the patient's head to draw the frame against the patient's face, and
- wherein the hollow tube is configured to extend from the first nasal side of the patient, to ascend towards a first temporal region of the patient, to further rise to a mid-point of the forehead of the patient at which the positive pressure breathing gas is received, to extend to a second temporal region of the patient, to reach the second nasal side of the patient, and to form a contour to at least partially encircle a nose and eyes of the patient.
A frame assembly for a ventilator to deliver gas, configured to deliver positive pressure breathing gas from a flow generator to an airway of a patient for treatment of sleep breathing disorders, the frame assembly for the ventilator to deliver gas comprising:

- two second interfaces configured to be provided on, respectively, a first nasal side and a second nasal side of the patient, and
- a symmetrical hollow tube, configured to be connected to the first interface positioned at a center of the frame and to the two second interfaces on both the first and the second nasal sides of the patient, rising to a mid-point of the forehead of the patient at which the positive pressure breathing gas is received, the symmetrical hollow tube configured to deliver positive pressure breathing gas from the first interface to the two second interfaces, the hollow tube comprising:
- a front wall,
- a back wall, and
- an inner edge and an outer edge formed at a junction of the front wall and the back wall;
- wing elements, integrally formed with the frame and made of silicone with a hardness of at or between 30 A to 70 A on a Shore scale, configured to connect to a headgear to secure the frame on a face of the patient, the wing elements are configured to extend towards an area above ears of the patient,
- wherein the wing elements have a force applied to the frame that is configured to extend towards a back part of the patient's head to draw the frame against the patient's face,
- a rigid interface configured to detachably connect to a patient interface cushion and being provided at an end of the second interface of the frame to form an undetachable connection with the two second interfaces.
A frame assembly for a ventilator to deliver gas, configured to deliver positive pressure breathing gas from a flow generator to an airway of a patient for treatment of sleep breathing disorders, the frame assembly for the ventilator to deliver gas comprising:
- a frame, made of continuous hollow elastomer, the frame comprising:
- a first interface to receive positive pressure breathing gas,
- a second interface configured to be provided near a nasal side of the patient, and
- a hollow tube configured to extend from the patient's eye and ear on each side to connect to both the first interface and the second interface and to rise to a mid-point of the forehead of the patient at which the positive pressure breathing gas is received;
- wing elements, integrally formed with the frame and made of silicone with a hardness of at or between 30 A to 70 A on a Shore scale, configured to connect to a headgear to secure the frame on a face of the patient, the wing elements are configured to extend from the hollow tube towards an area above ears and have at least one opening to connect to the headgear to provide the frame with a pulling force towards a back part of a head when in use,
- the pulling force being configured to draw the frame against the patient's face and pull a patient interface cushion nearer the airway of the patient;
- and
- wherein the hollow tube comprises:
- a support portion on an inner wall corresponding to the first interface configured to prevent a gas delivery device from bottoming out and sealing off a pressurized airflow when connected to the first interface.
A frame assembly for a ventilator to deliver gas, configured to deliver positive pressure breathing gas from a flow generator to an airway of a patient for treatment of sleep breathing disorders, the frame assembly for the ventilator to deliver gas comprising:
