OXYGEN CONCENTRATOR FOR MEDICAL TREATMENT

摘要

A pressure varying adsorbing type oxygen concentrator used for home oxygen treatment and capable of providing device reliability assuring low rate of failure occurrence and adsorption stability assuring stable oxygen concentrating performance for long period, comprising at least one adsorption tube filled with adsorbent capable of adsorbing nitrogen more than oxygen and an air compressor for supplying air while pressurizing the air and/or discharging the air while reducing the pressure to and/or from the adsorption tube, characterized in that a nonwoven fabric filter for collecting seal material abrasion powder is installed in an air passage between the adsorption tube and the air compressor.
