OXYGEN CONCENTRATOR

摘要

An oxygen concentrator for supplying high concentration oxygen stably to a patient regardless of the environmental temperature and/or the flow rate of high concentration oxygen gas. The oxygen concentrator comprises an oxygen concentration sensor for detecting the concentration of oxygen gas produced from the oxygen concentrator, a temperature sensor for measuring the environmental temperature and/or a flow sensor. The oxygen concentrator performs control for maintaining the concentration of oxygen at a predetermined level by increasing/decreasing the quantity of air supplied by a pressurized air supply means based on the detection value of oxygen concentration, and changes a control means by the measurements of the temperature sensor and/or the flow sensor of the oxygen concentrator.
