Patent number: 9669178Abstract: A patient interface device includes a patient sealing assembly having a cushion and a frame member having a faceplate portion and an extension portion extending from the faceplate portion. The cushion is coupled to the faceplate portion. A forehead member engages the forehead of the patient, and a flexible elongated member is coupled to the extension portion. A drive assembly selectively causes the second end portion of the flexible elongated member to move relative to the extension portion in a first direction. Movement of the flexible elongated member relative to the extension portion in the first direction causes movement of the frame member relative to the forehead member in a second direction transverse to the first direction.Type: GrantFiled: May 16, 2012Date of Patent: June 6, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Justin Edward Rothermel, Steven Charles Stegman, Karl Herbert Beitzel, Jason Anthony Belton

Patent number: 9661989Abstract: An overtube device for use in intubation during an endoscopic procedure is disclosed. The device includes an outer tube and an inner tube. The outer tube includes a distal end, a proximal end, and a first handle disposed on the proximal end. The inner tube includes a distal end, a proximal end, and a second handle disposed on the proximal end. The inner tube is inserted through an entire length of the outer tube such that the inner tube extends beyond the outer tube. At the proximal end of the device, a proximal end of the first handle is connected to a distal end of the second handle. When the inner tube is co-axially inserted within the outer tube, a clearance exists between a length of the inner and outer tubes, and between a length of the inner tube and the endoscope. Methods of use are disclosed.Type: GrantFiled: May 31, 2005Date of Patent: May 30, 2017Assignee: U.S. ENDOSCOPY GROUP, INC.Inventors: Dean J. Secrest, K. Randall John, Christopher J. Kaye

Patent number: 9592359Abstract: A respiratory mask assembly includes a respiratory mask including a mask shell and a mask cushion, a forehead support adjustably coupled to the mask, and an angular adjustment member. The forehead support includes a joining member provided to the mask shell and a cushion frame pivotally mounted to the joining member. The cushion frame is adapted to be selectively locked against pivotal movement in at least three predetermined angular positions relative to the joining member by a tongue and slot arrangement. The angular adjustment member allows relative angular adjustment between the cushion frame and the joining member. The angular adjustment member includes a pair of flexible arms that are adapted to be flexed towards one another to disengage the tongue from a respective one of the slots, and releasing the flexible arms allows the flexible arms to resiliently flex away from one another to engage the tongue and the respective slot.Type: GrantFiled: May 14, 2012Date of Patent: March 14, 2017Assignee: ResMed LimitedInventors: Philip R. Kwok, Michael K. Gunaratnam, Perry D. Lithgow, Jonathan P. Harrison, Jonathan L. Liston, Robert S. Matchett, Robert E. Styles

Patent number: 9415181Abstract: A face mask that may be used for bag-mask ventilation, during the induction of general anesthesia for example, and allows for two-handed or ambidextrous use. The face mask includes a dome connected to a deformable rim, which forms an enclosed air space when the rim is pressed against a patient's face. The dome has a connection port and a contoured outer surface adjacent the connection port. The contoured outer surface includes contour features such as a pair of crossed composite recesses which may each receive a different one of a user's thumbs. The connection port is aligned with the patient's mouth when the mask is in use and an adapter may be included that attaches to the connection port and provides a ventilation port as well as an intubation port that is aligned with the mouth.Type: GrantFiled: November 5, 2013Date of Patent: August 16, 2016Assignees: The Regents of the University of Michigan, The Regents of the University of CaliforniaInventors: Joel L. Kileny, Jeffrey Plott, Albert J. Shih, Lance Patak, Kevin Tremper, Daniel Edward Lee
