| 20090114221 | Method and apparatus for backspill prevention - A backspill prevention apparatus prevents water from a humidifier portion of a positive airway pressure (PAP) device from reaching a blower motor of a PAP device. The backspill prevention apparatus can include a variety of different devices, and is placed somewhere along an air passageway between a blower motor and a humidifier portion of a PAP device. | 05-07-2009 |
| 20090288660 | NEGATIVE-PRESSURE ORAL APPARATUS AND METHOD FOR MAINTAINING NEGATIVE ORAL PRESSURE AND COLLECTING LIQUID - The present invention discloses a negative-pressure oral apparatus capable of relieving discomfort of soft tissues in the oral cavity and improving fixation of the oral apparatus to prevent the oral apparatus from falling off due to mouth opening. The oral apparatus is compact and elastic so that it fits various shapes and sizes of the oral cavity and is easy to be put on and taken off to provide convenience and safety to the user. In another embodiment, a method for maintaining a negative oral pressure and collecting liquid by coupling the oral apparatus to a liquid collecting apparatus capable of effectively providing the oral cavity with a negative pressure to expel liquid in the oral apparatus and deliver the liquid to an absorbing element in the liquid collecting apparatus so as to prevent liquid leakage or contamination. | 11-26-2009 |
| 20110114093 | AUTOMATIC FITMENT DETECTION AND FLOW CALIBRATION USING NON-CONTACT SENSING IN POWERED AIR PURIFYING RESPIRATORS - A method and apparatus for operating an powered, air-purifying respirator. The apparatus includes an air mask, an air pump, a hose connecting the mask to the air pump, a magnetic actuator disposed on a portion of the hose that engages a housing of the air pump and a controller that provides a predetermined air flow from the pump to the mask based upon a magnetic flux from the actuator. | 05-19-2011 |
| 20120325210 | COCKPIT OXYGEN MASK - A cockpit oxygen mask includes a mask body, an oxygen inhalation valve, a mixed air inhalation valve, an exhalation valve as well as a control device. At least the oxygen inhalation valve is signal-connected to the control device. The oxygen inhalation valve is designed as an electromagnetically actuatable valve, and includes at least one throughflow path which may be closed by a magnetically movable valve body, wherein the throughflow path is limited by a magnetizable wall, and wherein the wall includes at least one discontinuous location which deforms a magnetic field produced in the wall. | 12-27-2012 |
