Publication number: 20150000668Abstract: The invention relates to an emergency oxygen supply device for aircraft inhabitants, comprising a container, wherein an oxygen mask is positioned inside said container, a releasable cover and a latch mechanism comprising a latch locking said cover lid. According to the invention said latch mechanism comprises a permanent magnet interacting with a magnetisable element an exerting a magnetic holding force onto said magnetisable element to hold said latch in a locking position, wherein a solenoid is positioned adjacent to the permanent magnet, said solenoid being connected to a control unit said control unit being adapted to receive an opening signal and to provide a current flowing through said solenoid in response to such opening signal, wherein said solenoid is arranged and dimensioned such that the current flowing through said solenoid reduces said magnetic holding force to such a level that the latch is released in a n unlocking position.Type: ApplicationFiled: June 27, 2013Publication date: January 1, 2015Inventors: Marco Hollm, Hasso Weinmann, Andreas Westphal, Wolfgang Rittner, Rüdiger Meckes, Frederik Hoffman, Romain Ducos, Günter Boomgaarden, Benjamin Fleczok

Publication number: 20140373847Abstract: A full-face mask system for delivery of a supply of gas at positive pressure to a patient for medical treatment includes a shroud, a cushion module adapted to form a seal with the patient's nose and mouth, an elbow, and headgear. The cushion module includes a frame and a cushion. The frame includes an opening that releasably receives a distal end of the elbow with a snap-fit, wherein an inner edge of the opening and the distal end of the elbow together form a retention structure to retain the elbow to the frame.Type: ApplicationFiled: August 12, 2013Publication date: December 25, 2014Inventors: Eva NG, David James LOCKWOOD, Jamie Graeme WEHBEH, Zoran VALCIC, Errol Savio Alex D'SOUZA, Matthew EVES, Mahsita SARI

Publication number: 20140373835Abstract: In accordance with the present invention, there is provided is provided a tubing arrangement and associated connectors, including a delivery adaptor and a Y-connector, which may be used to facilitate the operative interface of a patient interface to a ventilator within a ventilation system. The delivery adaptor is connected between the outlet connector of the flow generator and the main delivery tube (i.e., the quad-lumen tube) in the ventilation system. The delivery adaptor functions to retain the pneumatic isolation of a sense line of the ventilation system from certain other lumens of the quad-lumen tube, and further connects one of the small lumens of the quad-lumen tube to an external oxygen source or an external humidification source. The oxygen or humidification is delivered to such lumen through the adaptor. The oxygen or humidification is then bled into the air stream at the outlet of such lumen which is at the Y-connector.Type: ApplicationFiled: June 25, 2013Publication date: December 25, 2014Inventors: Samir S. Ahmad, Mark J. Zechmeister, Enrico Brambilla, Leonardo Alberto Baloa Welzien

Patent number: 8915250Abstract: Described herein is a mask for delivery of gas, such as oxygen, to a patient and useable in a naso-gastric intubation procedure without disruption of the seal between the mask and the patient's face. The body of the mask includes a fenestration or opening through which the naso-gastric tube may be inserted. The fenestration is preferably shaped to support the tube in a manner that is comfortable for the patient and that eliminates or minimizes the amount of gas lost to the atmosphere outside the mask. In at least some embodiments, the fenestration is closed when a tube is not inserted therethrough so that the mask may be used normally without loss of the gas through the fenestration.Type: GrantFiled: May 11, 2011Date of Patent: December 23, 2014Assignee: CareFusion 207, Inc.Inventors: Greg J. Dugan, Khalid Said Mansour, Stephen J. Birch

Publication number: 20140366882Abstract: Apparatus for providing positive airway pressure therapy to the airways of a patient includes a mask, a gas delivery conduit coupled to the mask, and a vent located in the mask or near the mask in the gas delivery conduit, to allow washout of exhaled carbon dioxide. The vent includes a plurality of vent orifices, the vent orifices being constructed and arranged to be open in use at least during the inhalation and exhalation phases of the user's breathing cycle. Each of the vent orifices being molded into a surface as a curved flow path from an interior of the mask or gas delivery conduit to atmosphere so that a vent flow from each of the orifices is directed in different directions, into one another, and/or slightly offset from one another to create diffuse air flow.Type: ApplicationFiled: September 3, 2014Publication date: December 18, 2014Inventors: Eva NG, Robert Henry FRATER, Lee James VELISS, Barton John KENYON, Daniel Robert JUDSON, Robert Edward HENRY, Alison OLDENBURG, Renee Frances DOHERTY, Michael John REID
