    • A device is provided for producing a cold treatment gas from nitrogen and air for the cryotherapy of rheumatic diseases in which liquid nitrogen vaporizes and is mixed in the desired ratio with the dry air which is at a higher pressure. The device includes a vessel for the storage of the liquid nitrogen which has a capacity for carrying out at least one or more treatments. Heat exchanging apparatuses are installed in the vessel for channeling a portion of the air which is at a higher pressure. A blending intersection for blending vaporized nitrogen, cooled air and non-cooled air is attached to the vessel. A blower is provided with a dryer having an outlet pipe which branches to a connection with the blending intersection and to a connection with the heat exchanging apparatus.
    • 提供了一种用于从氮气和空气中产生冷处理气体的装置,用于冷冻治疗风湿性疾病,其中液氮蒸发并以所需的比例与处于较高压力的干燥空气混合。 该装置包括用于储存液氮的容器,该容器具有进行至少一种或多种处理的能力。 热交换装置安装在容器中,用于引导处于较高压力的空气的一部分。 将蒸发的氮气,冷却空气和非冷却空气的混合交叉连接到容器。 鼓风机设置有具有分支到与混合交叉口的连接的出口管和与热交换装置的连接的干燥器。
