人への適用も盛んに研究されている。この酸素富化手段
としては、従来酸素ボンベを用いている。In addition, its application to healthy people is being actively researched because it alleviates fatigue and provides a pleasant feeling. Conventionally, an oxygen cylinder is used as this oxygen enrichment means.
以下、上述した従来例について、図面を用いて今少し詳
細に説明する。Hereinafter, the above-mentioned conventional example will be explained in more detail with reference to the drawings.

いう欠点もある。Problems to be Solved by the Invention Conventionally, as mentioned above, a gas cylinder has been used to enrich the chamber with gas, but in this method, the flow rate supplied to the chamber can be adjusted using a valve. It is necessary to convert pressure to flow rate during operation, and the operation must be performed by a skilled person. Also, creating a certain concentration throughout the room requires very complicated operations such as mixing outside air. Furthermore, when using a gas cylinder whose concentration has been adjusted, the cost increases. Moreover,
Another disadvantage is that the supply may be temporarily interrupted when changing or refilling cylinders.

。In view of the above-mentioned drawbacks, the present invention uses a gas separation membrane unit using an organic membrane to supply gas at a required concentration and flow rate to a chamber by operating a switch.

ようにしたものである。Means for Solving the Problems In order to solve the above problems, the present invention provides a gas separation membrane unit, a suction pump that applies suction pressure to the gas separation membrane unit, and a control means that controls the rotation speed of the suction pump. The enriched gas is supplied to the chamber through a conduit.
作用 上述した本発明の作用は次のようになる。action The operation of the present invention described above is as follows.
有機膜を用いた気体分離膜ユニットに、吸引ポンプにて
圧力を与える。このとき吸引ポンプの排出口より、選択
された気体が富化され排出される。Pressure is applied to the gas separation membrane unit using an organic membrane using a suction pump. At this time, the selected gas is enriched and discharged from the discharge port of the suction pump.

離膜ユニットと組み合わせれば、この回転数制御により
、任意の圧ソバつまり任意の濃度、流量が設定できる。This enriched gas is sent into the chamber through a conduit, but at this time, the concentration and flow rate of the enriched gas are determined by the pressure applied to the membrane unit, so if the pressure is kept constant, the concentration and flow rate are stable.
Flow rate can be supplied. In the case of a positive displacement suction pump, the higher the rotation speed, the higher the discharge flow rate, so when combined with a gas separation membrane unit, this rotation speed control allows you to set any pressure soba, or any concentration and flow rate. .
又、稼動、休止はスイッチひとつで行え、ボンベの切替
え、補充時の一時的な供給のとたえもなくなる。In addition, operation and suspension can be performed with a single switch, eliminating the need for temporary supply during cylinder switching and refilling.
