Disclosed is a device for suctioning bodily fluids and supplying a fluid substance to a human or animal body, comprising a drive unit (1, 1', 1"； 2) having a drive (20), a pump head (30, 30', 30") driven by the drive (20), and a connecting part (5, 7', 4") which can be detachably connected to the drive unit (1, 1', 1"； 2) and has a tubing guide (555, 710', 43"). The tubing guide (555, 710', 43") is designed to receive a tubing (I) in such a way that said tubing in combination with the pump head (30, 30', 30") forms a peristaltic pump (3) with which the fluid substance can be delivered through the tubing (I) and to the human or animal body. The pump head (30, 30', 30") is integrated into the connecting part (5, 7', 4") and the drive unit (1, 1', 1"； 2) has a coupling element (24, 24') connected to the drive (20), for coupling the pump head (30, 30', 30") to said drive (20).
