呼吸器。 A gas supply section in which a cartridge cylinder filled with breathing gas is attached to a breathing chamber comprising a mouthpiece and an exhalation port and an inhalation port on both sides of the mouthpiece with the mouthpiece in between; An exhaust valve and an outside air intake pipe are respectively disposed outside the exhalation port, and an exhalation check valve that opens when exhalation is disposed at the exhalation port, and an intake check valve that opens when inhalation is disposed at the intake port and the intake port. The exhalation port and the inhalation port are connected to each other by a flexible annular tube equipped with a carbon dioxide remover to form a closed circuit, and are slidable toward the breathing port side of the breathing chamber. When moved outward, the breathing chamber is connected to the exhalation port and the outside air intake pipe is closed; when moved inward, the breathing chamber is connected to the outside air intake pipe and the exhalation port is closed.
A respiratory device characterized by being equipped with a slide valve that can switch communication between a breathing chamber and an exhalation port and an outside air intake pipe.
