Abstract: An oxygen system supplies either 100% oxygen to a demand valve in a or pulses of oxygen to the mask. Switching is automatic during a parachute descent. The system includes a valve manifold that is responsive to ambient pressure such that at low pressures it is configured to deliver gas from either an oxygen cylinder or an aircraft supply line to the mask demand valve and at higher pressures it is configured to deliver gas from the cylinder to a pulse gas delivery system. The mask also includes an inhalation valve that is closed if oxygen is supplied to the demand valve. Otherwise, the inhalation valve opens to allow ambient air to be drawn in and the pulse gas delivery system delivers a pulse of oxygen in response to the onset of inhalation.

Abstract: There is disclosed a lung demand valve comprising: a body within which is disposed a diaphragm and a valve assembly having a valve inlet, the valve assembly and diaphragm arranged to cooperate to control the delivery of breathable gas to a user. There is also provided a breathable gas inlet fluidically connected to the valve inlet inside the body and arranged to be fluidically connected to a supply of breathable gas; and a whistle coupled to the body. The whistle has a whistle inlet fluidically connected to the breathable gas inlet inside the body and a whistle outlet disposed outside the body. In use, when the pressure of the breathable gas in the breathable gas inlet is less than a threshold, breathable gas flows from the breathable gas inlet through the whistle inlet and outlet thereby causing the whistle to sound outside of the body.

Abstract: The delivery system has a control body in the form of a pendant to which oxygen is delivered and from which the oxygen is delivered to the patient. The body includes a reservoir which has a constant oxygen supply orifice. During rest conditions, the patient breathes only a portion of the reservoir contents. During physical activity, the patient breathes more deeply and inhales more oxygen from the reservoir. The reservoir has a flexible diaphragm and when breathing more deeply, the diaphragm moves to open a bolus oxygen supply valve to introduce a bolus of additional oxygen to the reservoir and thus to the patient.

Abstract: An airflow control valve (20) for use in a breathing apparatus (10) to control a flow of air from a pressurised air supply to a respirator. The valve comprises an inlet port (31) for connection to a pressurised air supply, and first (32) and second (33) outlets. The valve is configurable between a first position in which the inlet port is in restricted fluid communication with the first outlet to allow a restricted flow of air from the inlet port to the first outlet and in which the second outlet is sealed from the inlet port and, a second position in which the inlet port is in substantially unrestricted fluid communication with the second outlet to allow an unrestricted flow of air from the inlet port to the second outlet.

Abstract: A pulse oxygen system and methods for providing oxygen to a user are disclosed. An oxygen mask coupled to a metering valve is provided to a user. An oxygen prescription delivery amount is determined based on and as a function of a real-time operation condition. A metering valve timing is calculated based on the oxygen prescription delivery amount to obtain a pulse delivery time. A pressure and time regulated flow of the oxygen prescription delivery amount of pulsed oxygen is then dispensed to the oxygen mask for a duration of the pulse delivery time in response to detecting the user breathing through the oxygen mask.
