Abstract

The invention discloses a liner for a breathing mask and the breathing mask. The liner comprises a connecting portion, a frame or a bend assembly for being connected to the breathing mask, a face contact portion for making contact with the face of a patient, and a middle portion connected between the connecting portion and the face contact portion, wherein the face contact portion and the connecting portion are oppositely arranged in the axial direction of the liner, the face contact portion is formed by a thin film, the liner comprises an upper area, a lower area and a middle area connected between the upper area and the lower area in the peripheral direction of the liner, and the face contact portion at least extends in the middle area from the middle portion to the peripheral side of the liner and is bent towards the inner circumferential side of the liner so that the sections of the face contact portion and the middle portion are in the inward hook shape in the axial direction of the liner. The liner forms the two sealing areas through the face contact portion to form reliable sealing, so that the identical sealing effect is achieved by applying small supporting force, and the wearing comfort is improved.

Description

technical field [0001] The invention relates to the technical field of breathing masks, in particular to a liner for a breathing mask and a breathing mask with the liner. Background technique [0002] Wearing a breathing mask as a non-invasive ventilation therapy has been widely used in the treatment of obstructive sleep apnea (OSA), chronic obstructive pulmonary emphysema (COPD), etc. The breathing mask is connected to the ventilator by tubing to deliver continuous pressure ventilation (CPAP) or variable pressure ventilation to the patient's airway, such as bi-level pressure ventilation that varies with the patient's breathing cycle or with patient monitoring conditions Automatic pressure regulation ventilation. This type of pressure support therapy is also commonly used in conditions such as obstructive sleep hypopnea, upper airway resistance syndrome (UARS) or congestive heart failure. [0003] Respirators typically include a frame and a cushion. When the respirator is...
