摘要:
A patient interface of the present invention includes a faceplate including a plurality of headgear attachment elements, a seal member operatively coupled to the faceplate; and an adjustment mechanism coupling the seal member to the faceplate. The adjustment mechanism controls the position of the seal member relative to the faceplate such that the seal member is moveable from a first position to a second position and is maintained in the second position during use of the patient interface after being moved to the second position.
摘要:
A flexible connector that couples a delivery conduit to a patient interface device and a pressure support system that includes such a flexible connector. The flexible connector of the present invention prevents disruption of the seal between the patient interface and the patient's face. The flexible connector may have a bellows portion with a longitudinally directed portion, a narrowed neck portion, or a plurality of corrugations. The flexible connector may further have a swivel portion and/or an exhaust member, and/or a hinge member.
摘要:
A seal and a mask using a seal that includes a first end portion adapted to be coupled to a seal support, a second end portion adapted for sealing engagement with a face of a user, and a sidewall extending between the first end portion and the second end portion. The first end portion, second end portion, sidewall, or any combination thereof is formed from an elastomeric material having an elongation of at least 1000%. The seal preferably formed from a unitary piece of elastomeric material.
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 patient interface assembly for use with gas monitoring. The patient interface includes a mask shell having a portion that seals against the face of a patient and a mask attachment coupled to an opening of the shell. The mask attachment has a mask connection section coupled to the opening of the shell, an airway adapter section that serves as a gas measurement site for use in measuring a respiratory variable, and a breathing system connection section adapted to be coupled to a to a patient circuit. The gas measurement site, which includes a window, may be disposed on the conduit, the shell, or both. An access port, defined in the mask, the mask attachment, or both permits a sampling tube to be placed in fluid communication with an airway of a patient.
摘要:
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.
摘要:
A respiratory mask including a base plate adapted for connection to a gas source and a bladder secured to the base plate to form a generally fluid tight seal with the base plate, and defining at least one internal chamber with the base plate for receiving a fluidizing medium to fill the bladder and form a resilient cushion.
摘要:
A patient interface assembly that includes a patient interface device, a headgear, and coupling member joining the interface device to a headgear. In one embodiment, a spring biases the interface device against the face during use. In a further embodiment, the patient interface device is a nasal cushion having 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 and includes an adjustment assembly that allows for a simultaneous adjustment of multiple straps. An adjustment assembly on the headgear provides 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 couple the patient interface device to the headgear.
摘要:
A conduit coupling assembly for use in connection with a patient interface device. The conduit coupling assembly includes a coupling retention assembly for retaining the conduit coupling in a predetermined position with respect to the user's face, and an adjustment assembly that permits continuous adjustment of a position of the conduit coupling with respect to a user's face. The conduit coupling assembly is continuously adjustable and retainable in an adjusted position and orientation by the adjustment assembly.
