Abstract
A respiratory mask can be used to provide therapy to patients who also require a nasogastric (NG) tube. The mask seal can include a path that is designed to deform around an NG tube or other without lifting the mask away from a patient's face. The deforming path can help to minimize gaps that form between the patient's face and the mask seal as a result of the tube, thus reducing leaks and improving the efficacy of the treatment.
Claims26
A cushion for a respiratory mask, comprising:
- a face contacting portion having a face contacting surface configured to contact a face of a user and that surrounds nares and/or a mouth of the user;
- at least one conformable or compliant region located at least partially within the face contacting portion and that is more compliant and flexible than surrounding or adjacent portions of the cushion such that the at least one conformable or compliant region is configured to stretch and deform around a tube, wherein the at least one conformable or compliant region is configured to accommodate placement of the tube between the face contacting surface and the face of a user;
- wherein the at least one conformable or compliant region comprises a step in an external surface of the cushion, wherein a gap is defined within the step, and wherein the at least one conformable or compliant region is flexible enough to inflate under an air pressure that is applied by a prescribed therapy such that, in an absence of the placement of the tube between the face contacting surface and the face of the user in use, the inflation of the at least one conformable or compliant region is configured to at least partially fill the gap.
