20090145436 | BREATHING APPARATUS AND INSTALLATION PROVIDING PROTECTION AGAINST HYPOXIA - The invention relates to a breathing apparatus for an aircraft crew member comprising at least one breathing mask ( | 06-11-2009 |
20100024821 | COCKPIT OXYGEN BREATHING DEVICE - The invention relates to an oxygen breathing device, in particular for cockpit crew member of an aircraft, comprising a pressurized oxygen source for storing pressurized oxygen, an oxygen mask, adapted to fit to nose and mouth of a person to be supplied with oxygen from the pressurized oxygen source, an oxygen supply line connecting the pressurized oxygen source with the oxygen mask, a pressure regulator/safety valve coupled in the oxygen supply line to selectively open or shut off oxygen flow from the pressurized oxygen source to the oxygen mask and/or to control pressure of said oxygen supplied to the oxygen mask. According to the invention, such oxygen breathing device is improved by having a pneumatic seal adapted to pneumatically seal the pressurized oxygen source in a non-use condition, an opening device adapted to open the pneumatic seal in case of an emergency situation requiring oxygen supply to the person, a change over valve adapted to selectively supply oxygen from the pressurized oxygen source or pressurized air from a pressurized air source to the oxygen mask. | 02-04-2010 |
20100263669 | ANTI-ASPHYXIATION VALVES - An anti-asphyxiation valve is disclosed, which is adapted for incorporation within a breathing circuit including a ventilator. The valve comprises one or more apertures for enabling passage of gas between the breathing circuit and the atmosphere, and a valve member deformable between an open configuration in which the one or more apertures are at least partially exposed and the passage of gas therethrough is enabled, and a closed configuration in which the valve member occludes the one or more apertures and the passage of gas therethrough is substantially prevented. The valve member is adapted such that the pressure within the breathing circuit at which the valve member deforms from the open configuration to the closed configuration is greater than the pressure within the breathing circuit at which the valve member deforms from the closed configuration to the open configuration. | 10-21-2010 |
20110011403 | Crew Mask Regulator Mechanical Curve Matching Dilution Valve - A demand regulator with air dilution regulates the pressure and flow of a respiratory gas with an outlet leading to a respiratory mask. A dilution valve controlled by a Bourdon tube varies the ratio of atmospheric air to oxygen in a crew mask based on ambient pressure. The Bourdon tube in the dilution valve assembly flexes in response to changes in atmospheric pressure causing the dilution valve to gradually open or close. As altitude increases the dilution valve gradually closes causing more oxygen to be provided to the facemask. The amount of added oxygen for a given atmospheric pressure can be accurately controlled at all altitudes due to the greater adjustment available in the device for calibration and operation compared to the current art. This greater operational capability eliminates the excess use of oxygen at low to intermediate altitudes as is common problem with the current art. | 01-20-2011 |
20110226249 | Informative Accessories - An optimized system for providing medical support to a patient is disclosed. The system has a plurality of modular components that may be assembled to create a connection between a support machine and the patient wherein at least one of the modular components comprises an information tag for the storage of data and at least one of the modular components comprises an information sensor for the reading and transmission of the data. Once read and transmitted by the sensor, the data may be used to optimize the operation of the support machine. | 09-22-2011 |
20130037029 | OXYGEN BREATHING DEVICE WITH REDUNDANT SIGNAL TRANSMISSION - The invention relates to an arrangement of a plurality of oxygen breathing devices, in particular for providing oxygen to passenger or crew of an aircraft, each oxygen breathing device comprising an oxygen source, wherein oxygen is stored, in particular in chemically bound form or compressed form, an oxygen guiding device for guiding oxygen from the oxygen source to a person. According to the invention, an arrangement of a plurality of oxygen breathing devices is provided, wherein a first one of said plurality of oxygen breathing devices further comprises an integrated transmitter comprising a sender adapted for wireless communication with a receiver of a second one of said oxygen breathing devices and a receiver adapted for wireless communication with a sender of said second oxygen breathing device. | 02-14-2013 |
20130340760 | AIRCRAFT LAVATORY EMERGENCY OXYGEN DEVICE - An aircraft emergency oxygen dispensing device includes an oxygen storage vessel having a frangible pressure seal, and a manifold, a pressure regulator, one or more flow control valves connected to the oxygen storage vessel. The manifold includes an initiator for breaking the pressure seal to initiate a flow of oxygen. A flow controller controls the flow control valves to dispense small quantities of oxygen by a pulse oxygen system or a modulated oxygen system based on ambient cabin air pressure. In the pulse oxygen system, the flow controller further controls the flow control valves based on input from at least one breathing mask air pressure sensor that monitors the breathing of a user. | 12-26-2013 |
20140158134 | RESPIRATORY APPARATUS - A flow generator for generating a flow of pressurized breathable gas includes a cylindrical housing and a motor supported in the housing. The motor has a shaft having a first end and a second end opposite the first end. The shaft is generally coincident with an axis of the motor. A first impeller is attached to the first end of the shaft and a second impeller is attached to the second end of the shaft. A stator directs an air flow from the first impeller back towards the motor axis. The housing includes an inlet adjacent the first end of the shaft having an inlet axis generally coincident with the motor axis and at least one outlet between the first and second impellers. The at least one outlet has an outlet axis generally tangential to the motor axis. | 06-12-2014 |
