Actuating device and method for operating the actuating device, as well as a membrane pump having the actuating device and the membrane pump device, and a blood treatment apparatus having the membrane pump

摘要

The present invention relates to an operating device (1) for mechanically actuating a diaphragm pump device (2), the operating device comprising a mounting surface (7) for the diaphragm pump device (2) and a control fluid connection. It has a substrate (4) through which a control fluid line (33, 35) extends from (78, 79) to a control fluid opening (34, 36) in the mounting surface (7). The control fluid line (33, 35) includes a control fluid valve (74, 75) designed to modify the cross section of the control fluid line (33, 35). The actuating device also comprises an actuating device (9, 14) comprising a fluid actuator (38) located on the mounting surface (7) to provide actuating movement, and an actuating fluid line (85, 86) through the substrate (4). ) And a working fluid valve (81, 82) designed to change the cross section of the same. The control fluid valve (74, 75) and the working fluid valve (81, 82) are control devices (designed to electrically actuate the control fluid valve (74, 75) and the working fluid valve (81, 82). 70) electrically connected. The invention also relates to a diaphragm pump with an operating device of this kind and a diaphragm pump device of this kind, as well as a blood treatment apparatus with a diaphragm pump of this kind.
