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.

Locking mechanism for a modular organization system

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.

Apparatus and method for opening and closing an infusion tube clamp

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.

Drive device for the linear movement of an infusion syringe piston, infusion pump and method for replacing an infusion syringe

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.

Infusion pump with drive device and blocking mechanism for the infusion syringe piston drive head

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.

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.
