| 20080196727 | Patient Interface Assembly And System Using Same - A patient interface assembly that includes a patient interface device, a headgear, and pivoting 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. In a further embodiment, a pair of rigid connecting members couple the patient interface device to the headgear. | 08-21-2008 |
| 20080302366 | CUSHION FOR A PATIENT INTERFACE - A respiratory mask is provided having cushion and a shell wherein the cushion has a frustum portion that extends towards the face of the user to provide a larger more stable and comfortable interface with a user which is better able to conform to the complex geometry of the user's face. | 12-11-2008 |
| 20090032022 | Pressure Reducing Valve With Flexible Cuff - A pressure reducing valve for use in a system adapted to deliver a breathing gas to a patient. The pressure reducing valve is structured to communicate a flow of breathing gas to such a patient's airway during an inspiratory phase. The pressure reducing valve is structured to discharge the flow of breathing gas and a flow of exhaled gas to atmosphere during the expiratory phase. The flow of breathing gas and flow of exhaled gas are discharged to atmosphere through a number of exhaust ports. Because the flow of breathing gas and flow of exhalation gas are discharged through the exhaust ports, less effort is required by a patient during the expiratory phase. | 02-05-2009 |
| 20090272380 | EXHAUST PORT ASSEMBLY FOR A PRESSURE SUPPORT SYSTEM - An exhaust port assembly comprising a conduit carries a flow of gas. A vent assembly having a fixed exhaust area is provided on the conduit for venting a flow of exhaust gas from within the conduit to ambient atmosphere. The vent assembly is configured so as to minimize noise associated with the flow of exhaust gas passing to atmosphere, diffuse the flow of exhaust gas passing to ambient atmosphere over a relatively large area, and minimize the area occupied by the venting assembly on the conduit. | 11-05-2009 |
| 20100065060 | CUSHION INSIDE A CUSHION PATIENT INTERFACE - A patient interface device including a cushion assembly having a cushion-in-a-cushion arrangement and a system for supplying a flow of gas to a patient using such an interface device. The patient interface includes a mask shell having a patient side and an outer side opposite the patient side adapted for receiving a supply of gas. A seal cushion contacts a first area of a patient's face to form a seal therewith. A support cushion is disposed outside the seal cushion and includes a first end portion that contacts a second area of a patient's face. | 03-18-2010 |
| 20100236558 | PATIENT INTERFACE WITH FOREHEAD AND CHIN SUPPORT - 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. | 09-23-2010 |
| 20100307497 | MAGNETIC COUPLING ASSEMBLY AND METHOD OF USING SAME - A magnetic coupling assembly for use in coupling portions of a gas deliver system. The magnetic coupling assembly includes a first member and a second member to be coupled together. The attractive forces between the first plurality of magnetic elements on the first member and a second plurality of magnetic elements on the second member join these member. The poles of magnetic elements in the first and second plurality of magnetic elements is opposite that of an adjacent magnetic element. The first and second members are easily detached from one another simply by rotating the first member relative to the second member such that the magnetic poles of the magnetic elements in each plurality of magnetic elements become unaligned, causing an weakening of the attractive forces. | 12-09-2010 |
| 20110180070 | ADJUSTABLE CONDUIT COUPLING ASSEMBLY - 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. | 07-28-2011 |
