Estimating the term…
According to one aspect, there is provided a device (4) for providing supplemental oxygen to a subject (8), the device (4) comprising a subject interface (10) through which the subject (8) can inhale; a container (12) that has a first outlet (18) connected to the subject interface (10) to allow gas with an elevated oxygen level stored in the container (12) to be inhaled by the subject (8), a first inlet (24), and a material (15) for removing a specific gas from air passing through the container (12) to increase the oxygen content of the air passing through the container (12); and an air blower (14) that is connected to the first inlet (24) of the container (12) and that is configured to supply air into the container (12) as the subject (8) uses the device (4).
A device (4) for providing supplemental oxygen to a subject (8), the device (4) comprising:
A device (4) as claimed in any preceding claim, wherein the first inlet (24) and the first outlet (18) are arranged with respect to each other such that air blown into the container (12) through the first inlet (24) by the air blower (14) pushes out gas with an elevated oxygen level stored in the container (12) through the first outlet (18).
A device (4) as claimed in any preceding claim, the device (4) further comprising a check valve (26) positioned between the air blower (14) and the first inlet (24), the check valve (26) being configured to close when the pressure of the gas with an elevated oxygen level stored in the container (12) is above atmospheric pressure in order to prevent gas in the container (12) from flowing through the air blower (14) when the air blower (14) is deactivated, and being configured to open when the pressure of the gas with an elevated oxygen level stored in the container (12) is at or below atmospheric pressure in order to allow air to be supplied into the container (12) by the air blower (14).
A device (4) as claimed in any preceding claim, the device (4) further comprising:
A device (4) as claimed in any preceding claim, the device (4) further comprising:
