Embodiment Construction

[0052] figure 1 An embodiment of a pressure support system according to an embodiment is illustrated. pressure support system in figure 1 The whole is indicated with the reference numeral 10 . System 10 is configured to deliver a pressurized flow of breathable gas to the airway of subject 12 (also denoted herein as patient 12). The pressurized flow of breathable gas may be provided according to a particular therapy regimen designed to treat respiratory disorders, such as obesity hyperventilation syndrome (OHS), obstructive sleep apnea (OSA), and / or other respiratory disorders. Treatment regimens call for maintenance of mean tidal volumes, maintenance of respiratory rate, and / or maintenance of positive inspiratory and expiratory pressures.

[0053] System 10 is configured to provide therapy to patient 12 to ensure patient 12 is breathing at a therapeutic breathing rate. An example of such a treatment is the use of continuous positive airway pressure (CPAP) or bipositive air...

Abstract

The present invention relates to a sealing cushion (24) for a patient interface (16), wherein the cushion (24) comprises a nose bridge contacting area (40) that is configured to contact a nose bridge of a patient (12) during use of the cushion (24), wherein the nose bridge contacting area (40) comprises a material having a secant stiffness of less than 0.45 N / mm at a material strain between 0.1 and 1, wherein the secant stiffness is defined as tensile force applied to the material per unit width of the material divided by the material strain, wherein the material strain denotes a ratio of material extension in length per unit of original length of the material.

Description

technical field [0001] The present invention relates to a sealing gasket for a patient interface which may be used in particular in a pressure support system for providing a flow of breathable gas to a patient. Background technique [0002] Patient interfaces, such as facial masks in pressure support systems, are used to deliver a flow of breathable gas to the user. Gases like air, clean air, oxygen or any modification thereof are provided to the user (also referred to as the patient) via the patient interface in a pressurized or unpressurized manner. [0003] For several chronic ailments or diseases, the use of such a patient interface is necessary or at least advisable. [0004] A non-limiting example of such a disease is obstructive sleep apnea or obstructive sleep apnea syndrome (OSA). OSA is usually caused by blockage of the upper airways. It is characterized by repeated interruptions in breathing during sleep and is often associated with a drop in blood oxygen satur...
