    • A diversion device is provided for diverting breathing gas, which is laden with CO2, from a pressurized region of an arrangement that includes a breathing mask and serves for delivering a breathing gas at a pressure level that is above the ambient pressure. The device has a tubular stub structure which defines a breathing gas conduit that extends between an inlet cross section on the hose side and an outlet cross section on the mask side, and which is provided, in a region located between the inlet cross section and the outlet cross section, with an outflow orifice portion by way of which the breathing gas to be carried reaches the environment. In a region located between the outflow orifice portion and the outlet cross section on the mask side of the breathing gas conduit, a double-walled structure that surrounds the breathing gas conduit is embodied for sampling the breathing gas to be carried away from a mask interior, while largely circumventing the breathing gas conduit.
    • 提供了一种分流装置,用于从包括呼吸面罩的装置的加压区域转移呼吸气体,其中CO 2 2含有CO 2 2,并用于将呼吸气体以高于 环境压力。 该装置具有管状短截线结构,其限定了在软管侧的入口横截面和掩模侧的出口横截面之间延伸的呼吸气体导管,并且其设置在位于入口横截面和入口横截面之间的区域中 出口横截面,具有流出孔部分,通过该流出孔部分将携带的呼吸气体到达环境。 在位于呼吸气体管道的掩模侧的流出孔部分和出口横截面之间的区域中,包围呼吸气体导管的双壁结构被实施为对呼吸气体进行取样以从掩模内部 ,同时在很大程度上绕过呼吸气体导管。
