摘要:
A patient interface that includes a support body having a cushion and cheek interfaces. Collectively, the cushion and cheek interfaces operate to distribute compressive forces exerted on the user's face. The support body of the patient interface is constructed from a flexible material to impart additional adjustability to the cheek interfaces. The support body also has arcuate eyelets designed to provide a hinge between the headgear assembly and the support body.

A patient interface assembly that includes a patient interface device, a headgear, and coupling member joining the interface device to a headgear assembly. In one embodiment, a spring biases the patient interface device against the patient's face when in use. In a further embodiment, the patient interface device is a nasal cushion that includes a formable support mounted to the nasal cushion for providing support and adjustment of the nasal cushion to improve fit and comfort. The headgear assembly in one embodiment is a semi-rigid, minimal contact harness assembly and includes an adjustment assembly that allows for a simultaneous adjustment of multiple straps. An adjustment assembly on the headgear provide a gross adjustment of the position of the interface relative to the patient and a biasing force to urge the patient interface device against the patient's face. In a further embodiment, a pair of rigid connecting members coupling the patient interface device to the headgear.

A patient interface gas delivery mask having a forehead and chin support system including a forehead support, a chin support, and a system for supplying a flow of gas to a patient that incorporates such a mask, forehead support, and chin support. The forehead support includes a supporting arm which is adjustably mounted to the mask shell, thereby allowing the adjustment of the distance between the forehead support bracket and the mask shell in order to adjust for patient's of different sizes. A forehead support bracket is pivotally connected to the support arm. Likewise the chin support is also adjustably mounted to the mask shell.

A forehead pad that includes a base member having a first side adapted to be coupled to a forehead support member. The pad also includes a patient contacting member having a first side adapted to contact a surface of a patient. A neck portion couples a second side of the base member and a second side of the first patient contacting member. The neck portion includes at least one cutout to allow at least a portion of the first patient contacting member to move relative to the base member so that the patient contacting portion of the pad is self-aligning with the surface of the patient even if the base member is not parallel with the surface of the patient.
摘要:
A patient interface that reliably and comfortably seals a user's face by providing an oral-nasal mask that includes an integrated nasal interface. The patient interface includes a seal member having an oral cushion portion configured to surround the user's mouth and a nasal interface portion that provides an interface with the user's nose. The seal member, including the oral cushion portion and the nasal interface portion, is a unitary member. Finally, the nasal interface portion remains below the bridge of the nose.
摘要:
A patient interface assembly that includes a substantially rigid support and a patient interface device coupled to a first end of the support. A first arm is coupled to a first side of the support and a second arm is coupled to a second side of the support. A cross member spans between the first arm and the second arm such that the cross member is disposed under a patient's mandible when the patient interface assembly is worn by a user. An addition, a conduit is coupled to a second end of the support.
摘要:
A patient interface system having a patient interface and chin support system for supporting the patient interface on the patient and for supplying a flow of gas from a patient circuit to the patient interface. In one embodiment, the chin support is formed from flexible hollow chambered support and extends from either side of the patient interface curving downwardly in front of the patient's cheeks, around the outside of the patient's mouth, to a position beneath the patient's mandible. In another embodiment, the chin support is coupled to a conduit that is coupled to the patient interface. The chin support includes at least a portion that is disposed under the patient's mandible.
摘要:
A functionalised graphene oxide and a method of making a functionalized graphene oxide comprising: (i) oxidizing graphite to form graphite oxide wherein the graphene sheets which make up the graphite independently of each other have a basal plane fraction of carbon atoms in the sp2-hybridised state between 0.1 and 0.9, wherein the remainder fraction comprises sp3-hybridised carbon atoms which are bonded to oxygen groups selected from hydroxyl and/or epoxy and/or carboxylic acid; and (ii) exfoliating and in-situ functionalizing the graphite oxide surface with one or more functional groups such that fictionalization of the surface is effected at a concentration greater than one functional group per 100 carbon atoms and less than one functional group per six carbon atoms. The functionalized graphene oxide is dispersible at high concentrations in appropriate solvents without aggregating or precipitating over extended periods at room temperature.
