<p>PURPOSE: To provide a supplying system of gas for respiration capable of easily securing the working precision of a demand valve and positioning a gas generation means for respiration main body apart from a user, by setting the demand valve and an attached control means, etc., at the side of the user and the main body of the system apart from the user. CONSTITUTION: Oxygen from an oxygen generation means 1 stored in a pressure- fluctuating absorption type oxygen concentrating device 19 is switched by a continuous flow or flow pass switching means 2 controlled by a flow pass switching control means 3 of a continuous flow or a demand flow based on the detection result by a flow quantity detection means 4, and reaches an extended tube 6 as a duct means via a pass 5a or 5b, and is supplied to a user via a demand valve 7 based on the detection result of a respiration phase detection means 9 mounted on an at-hand-operator 12. As an automatic operation switching means provided to the operator 12, one built in a demand controller 8 in the at-hand-controller 12 is exemplified.</p> |
