Standard For Medical Oxygen Concentrators

Oxygen purity: The oxygen produced by medical oxygen concentrators should meet the technical requirements for medical oxygen specified in GB8982-2009, and the oxygen concentration should be ≥ 90% (V/V). This means that under the condition of a maximum flow rate of 5L/min, the oxygen concentration should reach this standard after 30 minutes of startup. ‌1
Airtightness of the pneumatic system: All fasteners should be securely connected without any looseness, and various pipelines and pipes should be arranged neatly, with no air leakage at their connections.
Noise limit: The noise level of medical oxygen concentrators should be ≤ 60dB (A) to ensure quietness during use.
Flow regulation: Flow regulation should be continuously adjustable within the rated flow range, with a tolerance of ± 10%, to meet the needs of different users.
Safety performance: The safety performance of medical oxygen concentrators should comply with the requirements of GB9706.1-2007, YY0732-2009, and YY0709-2009 to ensure safety during use.
