摘要： A device for controlling respirating gas in an anaesthesia or respiratory apparatus contains a multiplicity of control elements. Each control element has a control chamber with control lines and a respirating gas chamber with respiratory gas lines, the control chamber and respirating gas chamber being separated from one another by a closure element. The respirating gas chambers and the control chambers are combined with each other so that as few component parts as possible have to be disassembled and assembled to facilitate cleaning and disinfection. For this purpose, the control chambers are combined into one control block and the respirating gas chambers are combined into one respirating gas block, such that the two blocks can be coupled together into a unit with a common sealing plate defining closure elements. The control chambers and respirating gas chambers are separated and yet are arranged so that the control chambers coact with corresponding ones of the respirating gas chambers.

摘要： With closed respiratory systems, the patient's respiratory tract is tightly connected to a closed volume to which breathing gas is supplied only in the amount taken in by the patient. To this end, the breathing gas supply must be controlled. The controlled variable is either the pressure in the ventilating circuit, or the concentration of oxygen or the anesthetic gas in the breathing gas. A dropping pressure indicates either an increased consumption or a leak. To avoid insufficient or excessive loading of the patient, it is very important to be able to distinguish consumption from a leak. The inventive device makes this distinction possible. The breathing gas amounts are adjusted in the ventilating circuit at preset different pressures and are compared with each other, and the leak portion is computed therefrom.
摘要翻译：在闭合呼吸系统中，患者的呼吸道紧密连接到仅由患者摄取的量供给呼吸气体的闭合容积。为此，必须控制呼吸气体供应。受控变量是通气回路中的压力，或呼吸气体中的氧气或麻醉气体的浓度。降低的压力表示消耗增加或泄漏。为了避免患者的不充分或过度的负担，能够区分消耗和泄漏是非常重要的。本发明的装置使得这种区分成为可能。呼吸气体量在通风回路中以预先设定的不同压力进行调节，并进行比较，由此计算泄漏部分。
