A seal and a respiraoty mask having a seal adapted for confronting engagement with a surface of a user to form an interface therewith. The seal includes a first portion defined by a gel substance. In one embodiment, the seal includes a selectively formable substance adapted to be molded from a first pattern into a second pattern and to retain the second pattern responsive to being so molded. The seal and mask having the seal in this embodiment is tailored to patient by causing the formable portion of the seal to be placed in a malleable state, applying the seal to the patient while the formable portion is in the malleable state, and causing the formable portion to be placed in a fixed state to retain a shape generally conforming to the portion of the patient underlying the seal.

Patient contacting seal and mask using same

A nasal mask assembly that includes a seal member defined from a unitary piece of elastomeric material. The seal member defines a nose receiving cavity and has a first end portion and a second end portion generally opposite the first end portion. A first opening in the first end portion allows at least a portion of a nose to enter the nose receiving cavity such that the nares of the patient communicate with the nose receiving cavity. The seal member includes a neck portion defined in the second end portion and a second opening defined in the neck portion in communication with the nose receiving cavity. A reinforcement area is provided on the side walls of the seal member. The reinforcement area comprises a saddle shaped contoured area on each side of the seal member. Each saddle shaped area has an upper and a lower protrusion portion for providing supporting contact with the face.

Nasal mask and system using same

A respiratory mask having a flexible, mask seal portion for engagement with the face of a user, a gel forehead cushion and a rotatable elbow coupling having integral exhaust ports. The mask seal portion has a thin section which permits the mask to more easily adapt to the contour of the face of the user. The gel forehead cushion provides increased compliancy and resiliency to better adapt to multiple user physical profiles. The elbow coupling includes tapered through holes in a polycarbonate arc piece to provide a quiet passage of gas through the holes.

Respiratory mask

An apparatus for selectively positioning intraoral anatomic features of a human patient to enhance upper airway stability for use alone or in combination with positive airway pressure as therapeutic treatment for obstructive sleep apnea and other conditions, such as snoring, which are symptomatic of upper airway instability.

Intraoral apparatus for enhancing airway patency

The present invention discloses a nasal mask assembly that includes a seal member defined from a unitary piece of elastomeric material. The seal member defines a nose receiving cavity and has a first end portion and a second end portion generally opposite the first end portion. A first opening in the first end portion allows at least a portion of a nose to enter the nose receiving cavity such that the nares of the patient communicate with the nose receiving cavity. The seal member includes a neck portion defined in the second end portion and a second opening defined in the neck portion in communication with the nose receiving cavity. A reinforcement area is provided on the side walls of the seal member. The reinforcement area comprises a saddle shaped contoured area on each side of the seal member. Each saddle shaped area has an upper and a lower protrusion portion for providing supporting contact with the face.

Nasal mask seal

A low contact nasal mask assembly that includes a seal member defined from a unitary piece of elastomeric material. The seal member defines a nose receiving cavity and has a first end portion and a second end portion generally opposite the first end portion. A first open is defined in the first end portion to allow at least a portion of a nose of a patient to enter the nose receiving cavity such that the nares of the patient communicate with the nose receiving cavity. The seal member also includes a neck portion defined in the second end portion and a second opening defined in the neck portion in communication with the nose receiving cavity. In addition, an outside diameter of the seal member and an inside diameter of the seal member increase generally linearly from the second end portion to the first end portion to minimize contact of the seal member with a patient and to minimize dead space. Furthermore, a collar coupled to the neck portion of the seal member provides a plurality of headgear attachment points spaced apart from the seal member. Also, a conduit coupling member is coupled to the collar and provides a mounting by which the nasal mask selectively couples to a breathing circuit.
