<p><P>PROBLEM TO BE SOLVED: To provide an oxygen inhalator capable of reducing the consumption of a rechargeable battery by changing the rotational frequency of a motor of a compressor according to the cycle of oxygen feeding quantity estimated by an estimation means. <P>SOLUTION: The oxygen inhalator has an oxygen flow rate setting means for setting the oxygen feeding quantity. The consumption of electric power and the consumption of the rechargeable battery are reduced by estimating the cycle of oxygen feeding quantity to be fed based on the frequency of oxygen inhalation detected by a sensor of a demand valve 117 and changing the rotational frequency of the motor of the motor driving of the compressor to an optimum control pattern according to the estimated cycle of oxygen feeding quantity. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
