Abstract

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.
