Abstract: A medical fluid pump, such as a syringe pump or infusion pump, includes a housing, a front flap hinged to a front side of the housing, and a carrying handle pivotally connected to opposite first and second side surfaces. The carrying handle is pivotable from a storage position to a carrying position in which the carrying handle is disposed above the housing. A plurality of electrical and mechanical components, which are contained within the housing, are necessary for all of the intended functions of the medical fluid pump. A selection of components from the electrical and mechanical components are provided as tare elements, placed within the housing such that a center of gravity of the medical fluid pump is substantially below the carrying handle in the carrying position.

Abstract: A medical syringe pump includes a housing and a drive head movable linearly to the housing by a tube-shaped or rod-shaped retention arm for actuating a syringe inserted in the housing, for which purpose the retention arm is connected in an axially fixed manner with an advance carriage and is in engagement with an advance spindle via the advance carriage. The medical syringe pump includes a twist protection which protects the advance carriage from twisting about the axis of the retention arm.

Abstract: A medical fluid pump with an upper housing shell, a lower housing shell and a front lid pivotably hinged to the lower housing shell. A printed circuit board with essential control devices is arranged in the upper housing shell, and an energy storage is provided and fixed in the lower housing shell.

Abstract: A modular arrangement system for arranging medical devices, in particular infusion pumps, and a device having a housing which forms the modular arrangement system. The system has at least two arrangement modules which can be mechanically connected to one another. A first arrangement module has a first housing part with a first coupling structure arranged on at least two diametrically opposed sides. A second arrangement module has a second housing part adapted to be mounted on, below or laterally to the first housing part. The second housing part has a bar rotatably or slidably mounted in the second housing part for locking the two housing parts. The bar is designed in such a way that, by a singular actuation, it engages into the first coupling structure on at least two diametrically opposite sides of the first housing part, preferably simultaneously in an undercutting manner.

Abstract: A securing element for axially securing a shaft or a component on a shaft includes at least two sector elements that can be joined to each other to form an essentially closed ring form with a central through opening for the shaft. The sector elements have latching structures or snap-fit structures, by which they can be connected to each other. The latching structures include a groove-like indentation with a first snap-fit hook formed in a first one of the sector elements and a spring arm with a second snap-fit hook arranged on a second one of the sector elements and engaging in the indentation in the first sector element.

Abstract: A device for opening and closing an infusion tube clamp includes a slide link which is axially arranged to be movable on a flap and includes at least one projecting locking element for closing an infusion tube clamp. An infusion tube clamp includes a first clamping leg and a second clamping leg pivotally connected to each other at one end, and a keeper plate which is arranged on the first clamping leg. At the locking element, the slide link includes a slide link ramp at which a switching cam of the keeper plate is adapted to slide into a stress-free final closing position.

Abstract: The invention relates to a drive device for linear movement of an infusion syringe piston of an infusion syringe disposed on an infusion pump comprising a drive head unit including a main bearing means for supporting the infusion syringe piston, a fixing means for securing the infusion syringe piston to the main bearing unit as well as means for triggering the fixing means and comprising an advancing means for the drive head unit including a motor-drivable advancing spindle and a multi-part advancing spindle nut having at least one radially movable nut shell, wherein the drive head unit additionally comprises detecting means for detecting the infusion syringe piston ahead of the main bearing means, the detecting means including a multi-threshold sensor unit comprising an at least two-stage upstream detection means for detecting different positions of the infusion syringe piston ahead of the main bearing means.

Abstract: A drive device of an infusion syringe piston drive head for moving an infusion syringe piston is described. The device includes an advancing means including an advancing slide, an advancing spindle and a multi-part advancing spindle nut having at least one radially movable nut shell, and a blocking means adapted to be automatically triggered by a control sensor for blocking an infeed motion of the drive head in which the advancing slide is drivable by the advancing spindle nut at the advancing spindle and in which the drive head is arranged at the advancing slide, wherein the blocking means adapted to be automatically triggered by a control sensor includes the multi-part advancing spindle nut for blocking the infeed motion of the drive head on the advancing spindle.

Abstract: The invention relates to an infusion tube clamp for being inserted in an infusion pump comprising a base member having an infusion pump receiving area, a first clamping leg, and a second clamping leg for squeezing an infusion tube, wherein the two clamping legs are swivel-connected to each other at a first infusion tube clamp end. The infusion tube clamp also includes a click device for safely positioning the two clamping legs in more than one position relative to each other.

Abstract: The syringe pump comprises a receiving position for a syringe. The piston plate of the syringe is moved by a drive head which is fastened to a drive rod. For locking the piston rod prior to fixing the piston plate in the drive head, a braking element is provided on a syringe holding head. The syringe holding head further serves for determining the respective syringe size. After placing the syringe holding head against a syringe cylinder, the brake element is actuated to temporarily engage the piston rod and fix it relatively to the syringe cylinder.

Abstract: A pump hose for a peristaltic pump consists of two arcuate portions that merge along kink lines so that the undeformed hose lumen has the cross-sectional shape of a convex lens. The joinings of the arcuate portions are joined by outwardly extending ribs. When the hose is pressed, only minor squeezing occurs at the joinings. The hose has a considerably improved squeezing and restoring behavior. The ribs prevent an excessive squeezing.
