摘要

The invention relates to an actuating device (1) for mechanically controlling a membrane pump device (2), having a base body (4) which comprises a mounting face (7) for a membrane pump device (2) and through which a control fluid line (33, 35) passes which extends from a control fluid port (78, 79) to a control fluid opening (34, 36) which opens at the mounting face (7), a control fluid valve (74, 75) being arranged in the control fluid line (33, 35), which control fluid valve is designed to influence a cross section of the control fluid line (33, 35), and having an adjustment device (9, 14), which comprises a fluid actuator (38) arranged on the mounting face (7) for providing an adjustment movement, and a working fluid valve (81, 82) which is designed to influence a cross section of a working fluid line (85, 86) which passes through the base body (4), and the control fluid valve (74, 75) and the working fluid valve (81, 82) being electrically connected to a control device (70) which is designed to electrically control the control fluid valve (74, 75) and the working fluid valve (81, 82). Moreover, the invention relates to a membrane pump which has such an actuating device and such a membrane pump device, as well as to a blood treatment device which has such a membrane pump.
