Abstract: A plate provides guides for preferably two screws, which hold the screws in a stable way at an angle against the plate. Furthermore, the screws are preferably fixed in a stable and removable way with a clamping device against rotations around the screw barrel and shifts in the direction of the screw barrel. For this a special screw is suitable with an outer thread diameter, which is larger than the neighboring barrel diameter. To ensure a secure guidance, the barrel diameter is enlarged in the area of the screw head.

Abstract: The blood pump (BP) has an elongate tubular pump housing (10) wherein a motor (16) is arranged that drives a pump impeller wheel (22), the pump housing having an inlet (12) at one end and an outlet (18) at the opposite end. The motor (16) comprises a motor housing (15) sealed off against the blood flow. The pump impeller wheel (22) is located at the end of the motor housing (15) facing the inlet (12) and, together with a transition portion (13) of the pump housing (10), forms a rotary pump flown through diagonally, which creates an axial flow flowing around the motor housing (15). Here, the blood flow exclusively flows between stationary parts, thereby reducing the risk of blood decay caused by shear stresses.

Abstract: Apparatus for processing fluids, in particular blood, includes a housing having an fluid inlet port and a fluid outlet port, with the housing being formed by an outer tube, an intermediate tube set within the outer tube for forming a first chamber therebetween, and an inner tube set within the intermediate for forming a second chamber therebetween. Disposed within the chambers are a plurality of hollow fiber membranes for suitably conducting heat exchange fluid and gas. The first and second chambers are so interconnected to one another and the inlet port and outlet ports are so disposed as to effect a fluid flow path through the chambers in longitudinal direction of the tubes.
