Abstract:
A fireproof device, an oxygen therapy instrument, and a ventilation therapy system, which relate to the technical field of medical devices. The fireproof device comprises: a housing (10), a valve body (20), a torsion spring (30), and a fusible member (40), wherein a fluid channel (101) is provided in the housing (10), the fluid channel (101) is provided with a first opening (102) and a second opening (103), and the first opening (102) and the second opening (103) are respectively configured to communicate with a pipeline of an oxygen therapy instrument end or a patient end; the valve body (20) is located in the fluid channel (101) and is rotatably connected to the housing (10); the valve body (20) is provided with an accommodation cavity (201), and the fluid channel (101) and the accommodation cavity (201) are two independent spaces; the torsion spring (30) is embedded in the accommodation cavity (201) and configured to drive the valve body (20) to rotate relative to the housing (10); and the fusible member (40) is arranged on an inner wall of the fluid channel (101). When the fusible member (40) is in a non-fused state, the fusible member (40) supports the valve body (20) to be in a first position, where both the first opening (102) and the second opening (103) are in an open state; and when the fusible member (40) is in a fused state, the torsion spring (30) rotates the valve body (20) to a second position, wherein at least one of the first opening (102) and the second opening (103) is in a closed state.
