本発明は選択性酸素分離膜を利用した医療用酸素富化装

て説明する。Conventional Structure and Problems In a conventional oxygen enrichment device that supplies oxygen-enriched air from fresh air through a membrane, the humidity is constant because the system conditions are fixed. One embodiment will be described based on FIG. 1.

される。In the figure, fresh air entering the device is supplied through a filter 1 to a cirselective oxygen separation membrane 2. The oxygen-enriched air that has passed through the selective oxygen separation membrane 2 by the vacuum pump 3 is cooled by the heat exchanger 4 and dehumidified by the adiabatic expansion chamber 6. After that, the air passes through a filter 6, a flow meter 7, etc., and then is discharged through an oxygen-enriched air outlet 8. The degree of vacuum on the secondary side (permeation side) of the selective oxygen separation membrane 2 is measured by a vacuum gauge 9. On the other hand, the air that has not passed through the selective oxygen separation membrane 2 becomes nitrogen-enriched air, and is discharged through the nitrogen-enriched air outlet 11 while cooling the heat exchanger 4 by the fan 10.

に最適な湿度の酸素富化空気を供給できない欠点を有し
ていた。Since the humidity contained in the water enriched air is uniquely determined by factors such as the capacity of the heat exchanger 4 and the capacity of the adiabatic expansion chamber 5, it becomes impossible to adjust the humidity. As a result, it has the disadvantage that oxygen-enriched air with optimal humidity cannot be supplied to the patient.
発明の目的
本発明は上記欠点を解消するもので、使用条件に合一っ
た湿度調整を簡単にできることを目的とする。OBJECTS OF THE INVENTION The present invention is intended to eliminate the above-mentioned drawbacks, and an object thereof is to easily adjust the humidity in accordance with the conditions of use.

化空気の湿度を任意に調節することが可能となる。Structure of the Invention The oxygen enrichment device of the present invention is provided with a pressure regulating means such as a pressure regulating valve or an exchangeable orifice at the outlet of the heat exchanger,
Humidity, which adjusts the internal pressure of the heat exchanger to approximately Q~0.2 Kg/cA, is the percentage of water vapor pressure to the saturated vapor pressure, and water vapor pressure follows the gas equation of state, so the above By adjusting the pressure inside the heat exchanger, the humidity of the oxygen-enriched air can be adjusted as desired.
実施例の説明 本発明の一実施例を第２図に基づいて説明する。Description of examples An embodiment of the present invention will be described based on FIG. 2.

の望む任意の湿度となって供給される。The oxygen-enriched air that has passed through the selective oxygen separation membrane 2 is sent to a heat exchanger 4 by a vacuum pump 3, where it is cooled and dehumidified. Thereafter, the pressure is adjusted to a desired level using a pressure adjustment valve or an exchangeable orifice as a pressure adjustment means, and further dehumidified in the adiabatic expansion chamber 5. As a result, the humidity in the oxygen-enriched air is supplied at any humidity desired by the patient.
発明の効果

気体の状態方程式に沿って冷却除湿を行う。Effects of the Invention As described above, according to the present invention, a pressure adjustment means is provided between the heat exchanger and the adiabatic expansion chamber, and the pressure inside the heat exchanger is adjusted.
Cooling and dehumidification is performed according to the gas equation of state.
従って圧力調整手段を調整することにより湿度のコント

できるものである。Therefore, by adjusting the pressure regulating means, it is possible to control the humidity and supply optimal oxygen-enriched air to the patient.
