A patient interface face contact () element comprises a surface for contacting the face of a patient, and a connection face for coupling the patient interface face contact element to a support () using a magnetic coupling (). The support is also provided as well as the complete patient interface. Headgear strap clips can also be retained magnetically.

A patient interface device includes a cushion member having a main body portion having a surface structured to engage a face of a patient. A frame member is coupled to the cushion member, and a fluid coupling conduit is coupled to the frame member. An engagement member is coupled to the cushion member; and a rotatable cam wheel is disposed between the frame member and the engagement member. Rotation of the cam wheel changes a position of the main body portion relative to the frame member. The cushion member includes a flexible portion adjacent the main body portion, and the cam wheel is rotatable about the flexible portion, such that rotation of the cam wheel about the flexible portion causes the flexible portion to deflect thereby moving the cushion member relative to the frame member.

A patient interface device that includes a support member sized and configured to span at least a portion of a patient's face while remaining below the patient's eyes responsive to the patient interface device being donned by such a patient and a sealing assembly operatively coupled to the support member such that the support member is moveable relative to the support member. The support member defines a gas carrying conduit adapted to carry a flow of gas to the sealing assembly. The support member is a single-piece unitary member and includes a conduit coupling portion adapted to be coupled to a patient circuit.

Patient interface device

Patient interface devices () structured to deliver a flow of breathing gas to an airway of a patient include a member () structured to contact and adhere to a face of the patient responsive to the patient interface being donned by the patient, the member having a contact surface and an adhesive layer () provided on the contact surface.

Patient interface devices with adhesive attachnment

A patient interface device () that includes a support member () comprising a central support portion and of cheek mount supports () coupled to the central portion. Each cheek mount support is configured to apply a force a side a user's cheekbone while applying substantially no force over an apex of such a user's cheekbone responsive to the patient interface being worn by a user. A seal member () is coupled to the support portion. The seal member is adapted to seal against a surface of a user to communicate a flow of gas with an airway of such a user. A conduit coupling member () is coupled to the seal member.

Patient interface device with cheekbone stabilization

An elongated flexible conduit () includes an flow element () having a first elongated wall segment () and a second elongated wall segment () that are connected together at their sides to form a wall () that is continuous in a circumferential direction perpendicular to the direction of elongation (). The flow element is movable between a first configuration and a second configuration (), with the first configuration being an expanded configuration, and with the second configuration being a collapsed configuration. The flow element can be moved from its expanded configuration to its collapsed configuration, such as for purposes of packing during traveling, and can then be moved from its collapsed configuration back to its expanded configuration in any of a variety of fashions in order to return the flow element to a condition in which it can carry a flow of breathing gas from a CPAP machine () to a CPAP mask ().

Collapsible patient conduit a respiratory therapy system

A patient interface device includes a support structure, a pivot arm pivotably coupled to the support structure and structured to pivot about an axis, a patient coupling member, such as a mask or a forehead support, coupled to the pivot arm, and a cam wheel rotateably coupled to the support structure and engaging the pivot arm, wherein rotation of the cam wheel relative to the support structure and the pivot arm causes the pivot arm to pivot about the axis and the patient coupling member to move either forward or backward along a path of movement. Also, an alternative patient interface device includes a cam wheel rotatable about a cushion member that changes a position of a main body portion of the cushion member relative to a headgear frame member of the patient interface device.

A strap member for use in securing a mask to the head of a patient includes a strap portion formed from a first material. The first material comprises a silicone material. The strap member further includes a breathability enhancing element associated with the strap portion.

Condensation management techniques for a gas flow delivery system. The techniques include providing a radiant barrier associated with patient circuit and/or a patient interface, providing a water trap and/or an absorbent insert in the patient interface device, or a combination of these techniques. The radiant barrier prevents condensation from forming in the patient circuit and/or the patient interface. The water trap and absorbent insert in the patient interface control condensation that reaches or forms in the interior of the patient interface to prevent it from interfering the user of the gas delivery system.
