PNEUMATIC MODULE AND PROCESS FOR SUPPLYING A CONSUMER WITH A PRESSURE SURGE-FREE STREAM OF MEDICAL GASES OR MEDICAL AIR

A pneumatic module (1) and a process supply a patient with breathing gas. An inlet (2) connects a medical gas source and an outlet (3) via a main flow duct (4) with a flow valve (5), setting a downstream volume flow, and a pressure relief valve (6) downstream of the flow valve (5) that vents the mai...

More Information
Summary:A pneumatic module (1) and a process supply a patient with breathing gas. An inlet (2) connects a medical gas source and an outlet (3) via a main flow duct (4) with a flow valve (5), setting a downstream volume flow, and a pressure relief valve (6) downstream of the flow valve (5) that vents the main flow duct (4) when a pressure is exceeded. A control duct (7), connected to a relief valve control port (8), branches off from the main flow duct (4) at a branch (15) upstream of the flow valve (5). A pressure control unit (9), arranged in the control duct, sets a flow value through the control duct (7), and acts on the control port (8) for setting a maximum pressure. The control port (8) is connected to a compensating element (10) providing a compensating volume (11) for the control duct (7).
