Abstract:
A fluid passage/stop body (4), component, housing and apparatus, a ventilation treatment device, and an oxygen supply control method. The fluid passage/stop body (4) comprises a sliding plate (7) and a flexible connecting member; the flexible connecting member is connected to the sliding plate (7); the flexible connecting member is used for connecting to a first channel wall (11) of a first fluid channel (1) of a fluid passage/stop apparatus; and the sliding plate (7) is used for moving, driven by the pressure of a fluid in the first fluid channel (11), to drive the flexible connecting member to flexibly deform. The fluid passage/stop body (4) is simple in structure, can drive, in actual use, a passage/stop member (5) to safely and reliably achieve the passage/stop of a fluid, and can significantly improve, in a ventilation treatment device, the safety of oxygen supply of the ventilation treatment device.
