Medical oxygen concentrator |
| abstract |
[PROBLEMS] A pressure-fluctuation adsorption type oxygen having adsorption performance stability which is intended to be used for home oxygen therapy and which guarantees a low failure rate and guarantees stable oxygen enrichment performance over a long period of time. Provide a concentrator. A pressure having at least one adsorption column filled with an adsorbent capable of selectively adsorbing nitrogen over oxygen and an air compressor for supplying air to the adsorption column and / or exhausting air under reduced pressure. A variable oxygen concentrator, comprising a nonwoven fabric filter for collecting abrasion powder from a sealing material between the adsorption cylinder and an air passage of the air compressor.
