PATIENT INTERFACE DEVICE WITH CUSTOMIZABLE CUSHION

摘要

A patient interface device (8) includes a cushion assembly (100) that is customizable to compensate for anatomical variances from patient-to-patient and, therefore, provides an effective seal with the patient's face. The cushion assembly includes a cushion member (102) having a first side structured to engage the patient's face, and a second side disposed opposite the first side, a plurality of plate members (108, 110, 112, 114, 116), and an adjustment mechanism (120, 122, 124). The adjustment mechanism is structured to adjust the position of the plate members, thereby changing the shape of the cushion member to gener ally conform to the patient's face.

主权项

1. A cushion assembly for a patient interface device, the cushion assembly comprising:
a cushion member including a first side structured to engage a patient's face, and a second side disposed opposite the first side; a plurality of plate members, the plate members being spaced apart from one another, thereby forming a groove in the cushion member between adjacent plate members; and an adjustment mechanism for adjusting the position of the plate members, thereby changing the shape of the cushion member to generally conform to the patient's face, wherein the adjustment mechanism comprises a number of connecting members each connecting a plurality of the plate members together and including a securing mechanism, wherein the connecting members are adjustable to move the plate members, thereby changing the spacing of the groove disposed therebetween; and wherein the securing mechanism secures the connecting member and the corresponding plate members in the desired position.
