Abstract
A fluid passage/stop body, component, housing and apparatus, a ventilation treatment device, and an oxygen supply control method. The fluid passage/stop body comprises a sliding plate and a flexible connecting member; the flexible connecting member is connected to the sliding plate; the flexible connecting member is used for connecting to a first channel wall of a first fluid channel of a fluid passage/stop apparatus; and the sliding plate is used for moving, driven by the pressure of a fluid in the first fluid channel, to drive the flexible connecting member to flexibly deform. The fluid passage/stop body is simple in structure, can drive, in actual use, a passage/stop member 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.
