Problems solved by technology

However, the force-bearing area between the middle part and the patient's face is small, which may cause the middle part to form a more obvious sense of pressure on the face
Although the double-layer film gasket can take into account the support and sealing performance, the structure of the double-layer film is usually complicated in manufacturing process, high in cost, inconvenient to clean, and not high in comfort

Abstract

The invention provides a breathing mask, an a pad and interface module for the breathing mask. The pad comprises a facial contact part and an intermediate part; the facial contact part is provided with a facial contact segment used for contacting the face of a patient and a connecting segment connecting to the facial contact segment, and the facial contact part is made from a first flexible material; the connecting segment of the facial contact part is connected to the first end of the intermediate part on the pad along the axial direction, and the intermediate part is made from a second flexible material; the Shore hardness of the first flexible material is greater than that of the second flexible material, and the thickness of the intermediate part is greater than that of the facial contact segment. By the arrangement that sealability and support performance of the pad are combined, convenience in washing is achieved, and the breathing mask is high in wearing comfortableness.

Description

technical field [0001] The invention relates to the technical field of breathing masks, in particular to a liner for a breathing mask, an interface assembly and a breathing mask. 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 respi...
