FIELD: medicine.
SUBSTANCE: group of inventions relates to a medical equipment, namely to a sealing cushion for a patient interface, comprising a nose bridge contacting area that is configured to contact a nose bridge of a patient during use of the cushion, wherein the nose bridge contacting area comprises a material having a secant stiffness of less than 0.2 N/mm at a material strain between 0.1 and 1, secant stiffness is defined as tensile force applied to the material per unit width of the material divided by the material strain, denoting a ratio of material extension in length per unit of original length of the material.
EFFECT: sealing cushion for a patient interface is proposed.
