    Abstract: The invention discloses a safety mechanical system by which emergency oxygen is delivered to motor vehicle occupants during an accidental water submersion of the vehicle. The system utilizes an oxygen filled tank located in the trunk, or another concealed area. The tank is connected to a manifold system with an automatic valve. The valve is activated and opened when a series of sensors detects that the vehicle is partially or fully submerged. Upon such detection, the valve is opened and oxygen is delivered through the manifold, then to a series of flexible tubes to a set of drop down masks that automatically deploy from an overhead console in the vehicle's headliner. The drop down assembly is of an adequate length of coiled hose similar to that found on a commercial airliner for oxygen use during sudden decompression. With such an installed system, vehicle occupants are provided with a mask and oxygen until they can be rescued or escape on their own.

  • Publication number: 20110011403
    Abstract: 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.

  • Publication number: 20100263669
    Abstract: 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.

  • Patent number: 7810498
    Abstract: A volume expansion system increases the storage volume for breathing gas in a closed-circuit breathing gas apparatus. A flow controller is coupled to an inhalation side of the closed-circuit breathing gas apparatus and is also coupled to an expandable reservoir. The flow controller defines a first flow path that allows breathing gas in the inhalation side to automatically flow into the expandable reservoir when pressure in the inhalation side exceeds a threshold. The flow controller can also include the means to define a second flow path that allows on-demand return of the breathing gas in the expandable reservoir to the inhalation side of the breathing gas apparatus.

  • Publication number: 20100236553
    Abstract: This disclosure describes systems and methods for compensating for leakage when during delivery of gas from a medical ventilator in a proportional assist mode to a patient. The technology described herein includes systems and methods to compensate the delivery of PA ventilation for leakage in the patient circuit by using leak-compensated lung flows as well as leak-compensated respiratory mechanics parameters (lung compliance and lung resistance) estimated in a manner that compensates for elastic and inelastic leaks from the ventilation system.

  • Patent number: 7793680
    Abstract: The electromechanical regulator for passenger oxygen is a hybrid oxygen regulator that provides for electronic or mechanical regulation of oxygen flow. The electronic portion of the regulator consists of an inlet solenoid valve, an outlet solenoid valve, a cabin pressure transducer, a regulated output transducer and a PID based controller, and the solenoid valves are normally biased so that in the event of an electronic system failure or a power supply failure the system will automatically revert to mechanical operation.

  • Patent number: 7784462
    Abstract: Aircraft passengers who require a therapeutic oxygen supply independently of the prevailing cabin pressure, as distinguished from an emergency oxygen supply that depends on an inadequate cabin pressure, can breath therapeutic oxygen and/or emergency oxygen depending on the situation, through the same therapeutic oxygen masks. For this purpose a control accessible to the crew is used to connect a therapeutic oxygen supply to the emergency oxygen distribution system of the aircraft, whereby the source of oxygen is used either partially for therapeutic purposes or fully for emergency purposes.

  • Patent number: 7708016
    Abstract: A gas regulator includes a delivery valve assembly having a delivery outlet and a delivery valve member engageable with the delivery outlet for controlling flow of a gas from a gas source. A timing gas chamber receives gas from the gas source. Gas pressure within the timing gas chamber controls the operation of the delivery valve member. An adjustment system controls the amount of time required for the gas to fill the timing gas chamber so as to control the length of time that the delivery valve assembly is opened to conserve gas. In other embodiments, a capacity adjustment system can adjust the capacity of a gas reservoir system.

  • Patent number: 7708015
    Abstract: A process, system and device are provided for automatically recording pressure-vs.-volume curves during artificial respiration with a respirator. The inspiration pressure is increased during the supply of a breathing gas volume flow under the control of a control unit. The resulting breathing gas volume flow rate is detected and the volume is determined from the latter by integration. The control unit compares the breathing gas volume flow detected during the phase of expiration with a preselected set point and acts on an expiration valve (12) in the expiration line (8) by means of a controller in case of deviation from the set point in order to return the breathing gas volume flow to the set point.

  • Patent number: 7686032
    Abstract: In a scuba diving first stage pressure regulator soft silicone rubber is bonded to the first stage spring to prevent water from freezing between the coils of the spring thereby assuring unrestricted movement of the spring coils even during freezing conditions. By placing a soft molded material bonded directly to the spring surface through the method of chemical and/or mechanical bonding, a soft pliable silicone rubber encapsulates or cocoons the entire area between spring coils and works as a barrier to prevent water from filling the regions between the spring coils and freezing in cold diving conditions. The thickness and volume of the pliable material silicone is not critical as long as the area between the coils is occupied with enough material to prevent ice from forming and otherwise preventing the spring from deflecting. Further, a radial clearance hole is needed to allow the piston to fit inside the silicone bonded spring hollowed center.
