Abstract
The portable aspiration pump unit of the invention, for the aspiration of bodily fluids, has a pump assembly housing (1) with a pump assembly (6) and at least one secretion or fluid collection reservoir (2) detachably connected to this pump assembly housing (1). The pump assembly housing has a front wall (11), a rear wall (10), and a side wall (16) arranged between these two walls, while the front wall and the rear wall each have one wall edge (100, 110) projecting beyond this side wall, and the fluid collection reservoir is held between these wall edges. In this way, the fluid collection reservoir can be secured easily to the pump assembly housing, yet be held firmly and protected inside it. This aspiration pump unit enables a simple and secure replacing of the fluid collection reservoir and affords the patient a heightened mobility.
