<p>PROBLEM TO BE SOLVED: To provide a small and light PSA type medical oxygen concentrator. SOLUTION: In the PSA type medical oxygen concentrator, a concentration detection means 16 for detecting the oxygen concentration of oxygen gas is connected to the outlet of a product tank 9 and its output signals are transmitted to a control part B18. A flow value (pure oxygen) per one minute, as indicated by an indicating part 17, is compared with the concentration of oxygen contained in the oxygen gas, and a control signal such that the amount of oxygen in the oxygen gas attains the flow value per one minute that is substantially equivalent to a value (prescribed value) indicated by the indicating part is outputted to a feed valve 21. Further, the oxygen concentrator is formed into a respiration-tuning-type in which the control signals are intermittently outputted by way of a respiration sensor 22, thereby, the oxygen concentrator can be further miniaturized.</p> |
