Patient interface device and maintaining apparatus and maintaining member therefor
First Claim
1. A maintaining member for a patient interface device, the patient interface device comprising a cushion member structured to engage a face of a patient to deliver a flow of breathing gas to an airway of the patient, the maintaining member comprising:
- a body structured to be disposed on a single side of the face of the patient, the single side of the face of the patient being either a left side of the face or a right side of the face, the body comprising;
a coupling portion structured to be coupled to the cushion member; and
a maintaining portion extending from the coupling portion, the maintaining portion having a receiving portion disposed opposite and facing the coupling portion, the receiving portion being structured to be disposed on a back side of a head of the patient and being concave facing in a direction toward the coupling portion in order to maintain the patient interface device on the face of the patient.

15. A patient interface device comprising:
-
a cushion member; and a maintaining apparatus comprising a maintaining member, the maintaining member comprising; a body structured to be disposed on a single side of the face of the patient, the body comprising; a coupling portion coupled to the cushion member; and a maintaining portion extending from the coupling portion, the maintaining portion having a receiving portion disposed opposite and facing the coupling portion, the receiving portion being concave facing in a direction toward the coupling portion in order to maintain the patient interface device on the face of the patient, and wherein the coupling portion has a first distal portion and a second distal portion each being structured to engage the cushion member, and wherein the first distal portion and the second distal portion are structured to move both away from one another and toward one another in order to allow the maintaining member to be coupled to the cushion member by a snap-fit mechanism.
