Abstract
A cushion for use with a patient interface device includes a first end portion, which typically contacts the patient's face when the patient interface device is worn, a second end and/or opposite the first end, which is typically coupled to a portion of the patient interface device, a chamber, which is typically disposed between the first and second end portions, and an orifice. The chamber is structured to receive and store a dampening medium therein; and the orifice, which is in operative communication with the chamber, controls the passage of the dampening medium into and/or out of the chamber. A patient interface device including a mask shell and the cushion is also described.
Claims29
A cushion for a patient interface device, the cushion comprising:
- a first end portion structured to contact a portion of a patient's face;
- a second end portion structured to couple to a portion of the patient interface device, the second end being opposite the first end;
- a chamber disposed between the first end and the second end, the chamber structured to receive and store a dampening medium therein;
- and
- an orifice in operative communication with the chamber, the orifice operable to control passage of such a dampening medium to and/or from the chamber.
A patient interface device comprising:
- a mask shell structured for receiving a flow of gas, the mask shell having a patient-side and an outer-side opposite the patient-side;
- and
- a cushion coupled to the mask shell, the cushion including a chamber and a number of orifices;
- wherein the chamber is structured to receive and store a dampening medium therein;
- and wherein the number of orifices are in operative communication with the chamber.
A cushioning system for a patient interface device, the cushioning system comprising:
- a first portion structured to provide active conformation in compression contact with a patient's face;
- and
- a second portion structured to provide passive position displacement, the second portion including a chamber with a dampening medium therein.
A cushion for a patient interface device, the cushion comprising:
- a first end portion structured to contact a portion of a patient's face;
- a second end portion coupled to a portion of the patient interface device, the second end being opposite the first end;
- and
- a dampening means disposed between the first end portion and the second end portion, the dampening means structured to provide passive position displacement.
A cushion for a patient interface device, the cushion comprising:
- a first end portion having a first end wall structured to contact a portion of a patient's face;
- a second end portion having a second end wall structured to be coupled to a portion of the patient interface device, the second end being opposite the first end;
- an outer wall connecting a first edge of the first end wall to a first edge of the second end wall;
- and
- an inner wall connecting a second edge of the first end wall to a second edge of the second end wall, wherein the first end portion, the second end portion, the inner wall, and the outer wall define a chamber therebetween.
