An oxygen generation apparatus of the first embodiment includes an outer container, a container lid, a piercing member, and an inner container. An annular flange is formed inside the inner container, and a surface of the annular flange is provided with two sealing films to accommodate an oxygen generating agent. The piercing member may move from a first position to a second position relative to the container lid, so as to break the sealing films to mix the oxygen generating agents to generate oxygen; an oxygen generation apparatus of the second embodiment includes two inner containers, where an annular flange is formed on one inner container to dispose a sealing film to accommodate an oxygen generating agent, a bottom surface of another inner container is provided in a concave manner with an accommodation space which accommodates the piercing member.

A portable oxygen generating system is provided that comprises a reaction chamber, a feed system for providing and controlling hydrogen peroxide solution to the reaction chamber, and a cooling/condensing system for cooling the hot oxygen and water vapor leaving the reactor and condensing and removing water. The portable chemical oxygen generation system produces humidified, breathable oxygen, that is substantially free of hydrogen peroxide and other contaminants, at a controlled flow and temperature over an extended period of time.

A respiratory system composes an oxygen supply, a vented respiratory mask, a hose coupled to the oxygen supply, and a connector apparatus joining the respiratory mask and the hose. The connector apparatus may comprise mask connector member to govern fluid flow through a vent in a mask, a mask valve received in a mask fluid flow passage movable between a rest position in which the mask fluid flow passage is blocked and an actuated position in which the mask fluid flow passage is unblocked, a biasing member biasing the mask valve towards the rest position, and a hose connector member to be secured to a fluid hose. The hose connector member includes a valve actuator to move the mask valve to the actuated position when the hose connector member is coupled to the mask connector member.
