    • A respiration system includes a patient connection (1), an inspiratory branch (3), an expiratory branch (13), a rebreathing line (99), a reservoir (25), a CO2 absorber (29), a radial compressor respiration drive (33), a fresh gas supply unit (51), an oxygen flushing device (55), connected to the rebreathing line, a pressure sensor (31) and an actuatable control valve (21), arranged in the rebreathing line between a second end (17) of the expiratory branch and the CO2 absorber. The compressor, oxygen flushing device and fresh gas supply unit are arranged in the rebreathing line between the CO2 absorber and a second end (7) of the inspiration branch. The compressor inlet points towards the CO2 absorber and the outlet points towards the second end of the inspiratory branch. The pressure sensor is arranged in the rebreathing line between the compressor and the second end of the inspiratory branch.

    • A respiration system feeds an anesthetic gas having, a density ρgas, with a Y-piece for connection to a patient, with a respiration circuit having an inspiration branch and an expiration branch, which extend away from the Y-piece. A first supply line from a branch in the expiration branch leads to an anesthetic gas discharge valve and a second supply line from the branch leads to a reservoir. A too high pressure, opposing expiration, cannot build up in the expiration branch and losses of anesthetic gas are kept to a minimum. A prestressing device exerts a prestressing force onto the valve body of the anesthetic gas discharge valve against the effect of gravity. The mass mvalve and the prestressing force determine a threshold pressure in the anesthetic gas discharge line that results in an opening of the anesthetic gas discharge valve.
    • 呼吸系统将具有密封气体的麻醉气体与用于连接到患者的Y形件一起进料,呼吸回路具有远离Y形件的吸气分支和呼气支路。 来自呼气支架中的分支的第一供应管线通向麻醉气体排出阀,并且来自分支的第二供应管线通向储液器。 过高的压力,相反的过期,不能在有效期内积累,麻醉气体的损失保持在最低限度。 预应力装置对重力作用施加麻醉气体排出阀的阀体上的预应力。 质量阀和预应力确定麻醉气体排放管道中的阈值压力,其导致麻醉气体排出阀的打开。
