A valve arrangement () is for a patient interface device () having a frame portion (). The valve arrangement includes a valve member () having a coupling portion () and a blocking portion () extending from the coupling portion. The coupling portion of the valve member is structured to be coupled to the frame portion. The blocking portion is structured to move between a first position and a second position. The valve arrangement further includes a guard member () having a coupling portion () and a protecting portion () extending from the coupling portion of the guard member. The coupling portion of the guard member is structured to be coupled to the frame portion. When the blocking portion of the valve member moves from the first position toward the second position, the blocking portion moves toward the protecting portion of the guard member.

Valve arrangement for full face mask

A patient interface device is for a pressure support system that includes a flow generator that produces a flow of breathing gas to be delivered to an airway of a patient. The patient interface device includes a sealing element to engage a face of the patient and receive the flow of breathing gas; a lumen having a first end and a second end opposite and distal the first end, the first end being in fluid communication with an interior of the sealing element; a connector member coupled to the second end of the lumen; a pressure sensor coupled to the connector member, the pressure sensor sensing pressure of a gas exiting the second end of the lumen; and a surface provided on one of the lumen and the connector member, the surface defining a thru hole through which undesirable liquid in the lumen can escape.

Liquid removal in a patient interface assembly

A ventilation mask () includes a mask body (), a frame () and an elbow (). The mask body has a first opening () and a sealing member () configured to engage the face of a patient so as to surround at least a mouth and a nose of the patient. The frame is connected to an outer surface of the mask body, and has an interface member () configured to interlock with the mask body at the first opening. The elbow has a first end () connectable with a gas supply, and a second end () configured to be fixedly secured to the interface member of the frame and to enable flow of gas from the elbow into the mask body through the first opening.

Snap-in elbow for patient interface mask

A mask assembly is provided for delivering gas to a patient that includes a mask body and a breathing circuit interface. The mask body includes an opening for reception of the gas and includes a seal structure for sealingly engaging with the face of the patient and surrounding at least the nose and mouth of the patient. The breathing circuit interface includes a first portion rotatably connected with the mask body and a second portion that is constructed and arranged to releasably connect with a conduit for delivering the gas to the patient through the opening.

Face mask

A patient interface device () includes a patient sealing assembly () including a cushion (), and a frame member () coupled to the cushion, and an adjustable forehead support assembly () provided at the distal end () of the frame member. The adjustable forehead support assembly includes an adjustment mechanism () coupled to a forehead cushion (), wherein the adjustment mechanism includes a forehead cushion support member () having a base portion () coupled to the forehead cushion and an vertical/upright rotatable wheel member (). Rotation of the wheel member causes movement of the frame member and the cushion relative to the forehead cushion.

Patient interface device including an adjustable forehead support having a vertical wheel drive mechanism

A patient interface device () includes a patient sealing assembly () including a cushion () and a frame member (), and an adjustable forehead support assembly () provided at the distal end () of the frame member. The assembly includes an adjustment mechanism () coupled to a forehead cushion (), the adjustment mechanism including a housing (), a forehead cushion support member () having a base portion () and an elongated post member () extending from the base portion and received within the housing, and a locking member () structured to be selectively coupled to the elongated post member. In the locked condition, the locking member engages the elongated post member and prevents the elongated post member from moving relative to the housing, and in the unlocked condition the locking member does not engage the elongated post member such that the elongated post member and the housing are freely linearly movable with respect to one another.

Adjustable locking forehead support for a patient interface device

A patient interface device () includes a patient sealing assembly () adapted to communicate a flow of breathing gas within an airway of a patient, the patient sealing assembly including a cushion (), a frame member () coupled to the cushion, and an adjustable forehead support assembly () coupled to the frame member. The adjustable forehead support assembly includes a forehead cushion () and an inflatable and deflatable bladder () coupled to the forehead cushion, wherein inflation and deflation of the bladder causes the distal end () of the frame member to move relative to the forehead cushion in a manner wherein a pressure applied to a bridge of a nose of the patient by the cushion is adjusted.

Patient interface device including a pneumatically adjusting forehead support

A patient interface device () includes a mask component () structured to engage a face of the patient, a head support member () structured to rest on a head of the patient, and a coupling arm () having a first end () coupled to the mask component and a second end () coupled to the head support member. The second end of the coupling arm is coupled to the head support member in a manner wherein the mask component is selectively moveable relative to the head support member in multiple planes such that the mask component can be rotated at least 180 degrees in a plane that is parallel to the patient's face.

Patient interface system with articulating forehead pad attachment

A patient interface device storage system includes a patient interface device structured to deliver a flow of breathing gas to a patient, the patient interface device including a mask, and a storage shell having an outer peripheral wall and a bottom wall which together define a cavity. The cavity is sized and configured to receive and hold at least a portion of the mask. The bottom wall includes a first attachment member structured to be selectively engaged with a second attachment member associated with a gas delivery device in a manner such that the storage shell and the patient interface device are coupled to and held by the second attachment member.

Patient interface device storage system

A patient interface system () that includes a patient interface assembly () and a headgear assembly (). The patient interface assembly () includes a frame (), a patient circuit connector (), a seal member (), and a coupling assembly () extending from the frame. The coupling assembly () is directed toward the users forehead when worn. The headgear assembly () includes an elongated pad support (), a headgear attachment element () disposed on the pad support (), a headgear strap () coupled to the headgear attachment element (), and an elongated headgear pad () coupled to the pad support (). The pad support, pad, or both are configured so as to extend from the forehead of the user generally along a centerline of the head and terminate proximate to a top of a head. In addition, a coupling assembly attachment assembly () is operatively coupled to the pad support () to couple the coupling assembly () of the patient interface device to the headgear assembly ().

Patient interface system

A mask assembly () is provided for delivering gas to a patient that includes a mask body () and a breathing circuit interface (). The mask body includes an opening () for reception of the gas and includes a seal structure () for sealingly engaging with the face of the patient and surrounding at least the nose and mouth of the patient. The breathing circuit interface includes a first portion () rotatably connected with the mask body and a second portion () that is constructed and arranged to releasably connect with a conduit () for delivering the gas to the patient through the opening.
