An occlusive peristaltic pump type fluid pump that includes a pump rotor rotatable in the fluid pump. The fluid pump includes a base, a first cover element fastened to an upper side of the base and a second cover element fastened to a lower side of the base, and at least one pressure element accommodated in the base and including a pressure member for occluding a fluid-guiding hollow conductor portion against a rounded bearing surface on a housing portion of the fluid pump. The at least one pressure element is linearly guided in the effective direction of an occlusion force by the first cover element and the second cover element.

Fluid pump

A peristaltic pump for an apparatus for extracorporeal blood treatment, especially for a dialysis machine, for delivering fluid in the apparatus is disclosed. The peristaltic pump includes a rotor driven to rotate about a rotor axis and a pump casing surrounding the rotor at least in part and including a supporting surface being configured to be curved around the rotor axis, wherein an elastically deformable fluid line is adapted to be positioned between the rotor and the supporting surface and is deformed between the rotor and the supporting surface while forming a cross-sectional constriction for fluid delivery by rotation of the rotor, the pump casing having a modular design and including a supporting surface module forming the supporting surface and a casing module adapted to be coupled to the former and surrounding the rotor at least in part.

Peristaltic pump comprising modular casing

A peristaltic pump for an apparatus for extracorporeal blood treatment, especially for a dialysis machine, for conveying fluid in the apparatus is disclosed. The peristaltic pump includes a rotor driven by a drive shaft, the rotor interacting with an elastically deformable fluid line so as to form a cross-sectional constriction which is displaced along the fluid line for conveying fluid by rotation of the rotor, wherein the rotor is coupled to the drive shaft by a coupling structure so as to transmit a torque, wherein the coupling structure couples the rotor and the drive shaft with a play in the direction of rotation relative to each other.

The invention relates to a medical apparatus for extracorporeal blood treatment, comprising an antimicrobial surface coating, wherein the antimicrobial surface coating is a powder coating. It further relates to a method for controlling microbes and microorganisms on a surface of a medical apparatus, wherein a powder coating contains components, in particular additives, with an antimicrobial effect.

Medical apparatus comprising an antimicrobial surface coating and method for controlling microorganisms on the surface of such an apparatus

A machine for extracorporeal blood treatment including a housing for accommodating operational components of the machine for extracorporeal blood treatment and a light-emitting unit having no diffusion disk for displaying an operating and/or therapy condition of the machine according to the principle of ambient light. The light-emitting unit is arranged in a predetermined sequence and/or with predetermined shaping on at least one portion of the housing. The light-emitting unit is a flexible light conductor having at least one end-face light coupling surface at a first end and at least one end-face light output surface at a second end or alternatively a self-luminous flat and/or flexible OLED unit.

Machine for extracorporeal blood treatment comprising light-emitting unit

A device for integrating a monitor in a case comprises a support element made from plastic material and having a recess which corresponds to a predetermined visible area of the monitor. The support element includes a plurality of apertures which are arranged at a predetermined distribution outside the recess for passing through positioning and/or retaining elements and placing the support element at a predetermined position on a sheet-metal case in which the support element can be received, and a frame section which projects from a base area of the support element on a rear side thereof and is arranged in sandwich design for receiving components of the monitor. The components of the monitor received in the frame section are adapted to be fixed to the support element, and the support element is adapted to be fixed to the at least one of positioning or retaining elements on the sheet-metal case.
