Abstract

A cushion pad for a mask worn by a patient, comprising a first side to contact skin of the patient, and a second side, opposite the first side, to contact or face the mask. The pad has a main body portion having a central portion shaped to cover a portion of the patient's nose extending from above the nose tip to the nasal bridge region without obstructing the patient's line of sight, and lateral side portions to extend downward and terminate along the sides of the nose or on the patient's cheeks. The main body is made of a breathable material, e.g., foam. The pad may include adhesive and / or an attached portion, e.g., a ring, to couple the pad to the patient and / or portion of the mask.

[0003] The invention relates to a cushion for a respiratory mask for respiratory therapy of a patient. Various respiratory conditions include sleep-disordered breathing (SDB), and specifically obstructive sleep apnea (OSA). Respiratory therapies for the treatment of these conditions include continuous positive airway pressure (CPAP), non-invasive positive airway pressure (NIPPV) and variable positive airway pressure (VPAP).

Embodiment Construction

[0042] Generally, a mask system includes a frame, a cushion, and a headgear. The frame anchors the pads in place and allows for the attachment of the headgear. Typically, the frame is a rigid or semi-rigid component, such as polycarbonate. The cushion can seal against the patient's face to provide therapy to the patient. Typically, the pad is a flexible element made, for example, of silicone. In use, the headgear secures and supports the frame and pads in place on the patient's face. Typically, headgear is a flexible or semi-rigid element, such as fabric.

[0043] Due to various reasons such as unique facial contours, some patients may have difficulty achieving a seal when the mask system is placed on the patient's face (dynamic as well as static). Some patients may experience discomfort such as irritation due to prolonged contact with the mask system, especially the cushions. Additionally, if a patient has broken skin that may come into contact with the mask system, the ...
