Cpap pressurized gas permeable mask cushion

Abstract

The present invention relates to a patient-contacting element (10) or a patient interface (12) including such a patient-contacting element (10) wherein the required minimum pressure for sealing may be realized for all different values of CPAP pressure. In particular, the present invention relates to a patient-contacting element (10) for a patient interface (12) for delivering a flow of gas to a user (20), said patient-contacting element (10) being configured to provide a substantially air-tight seal with the user's skin during use and comprises an inlet (14) for receiving at least part of the flow of gas (40), at least one gas-permeable element (16) that is disposed within the patient-contacting element (10) and arranged in fluidic communication with the inlet (14), and a first layer (18) of an air-tight material that is arranged between the at least one gas-permeable element (16) and an inner space (52) of the patient-contacting element (10) for receiving a nose and/or a mouth of the user (50), wherein the air-tight material has at least one opening (20) therein.
