  • Patent number: 11083839
    Abstract: An infusion arrangement for administering a medical fluid includes a pump apparatus with an elastomeric membrane which forms a pump volume. The elastomeric membrane is elastically extended in a fill state, filled at least partially with medical fluid, of the pump volume and produces a delivery pressure on the pump volume. An infusion line is connected to the pump volume and provided with a patient access for fluid-conducting connection. A main fluid channel transfers medical fluid from the pump volume to the patient access. A monitoring device is connected to the infusion line and configured for monitoring the pump apparatus. The monitoring device has a differential pressure-measuring element connected to the main fluid channel and designed such that differential pressure formed along a channel portion of the main fluid channel can be detected by the differential pressure-measuring element and a delivery rate of the medical fluid can be indicated.

  • Patent number: 10933215
    Abstract: A hose line includes a sheath extending axially between a first hose end and a second hose end, and has an outer face and an inner face, an axial passage enclosed by the inner face and extending between the hose ends, a radial passage which extends through the sheath and connects the axial passage to the outer face, and a closure which is arranged between the radial passage and the second hose end and closes the axial passage in a fluid-tight manner. The radial passage is formed by a sheath portion which is bent and partially separated from the rest of the sheath along a partition line. The closure is formed by placing the sheath portion onto the inner face and connecting the sheath portion to the inner face in a fluid-tight manner. The hose line can be used in a catheter hose line.

  • Patent number: 10857291
    Abstract: A medical pump, in particular an infusion pump for conveying a medium, includes a seating for a hose clamp which is separate from the pump and arranged on the hose. Two clamping portions of the hose clamp which can be moved relative to each other can be transferred into a closed relative position in which they pinch off the hose arranged therebetween in such a manner that it is not possible for any medium to flow through the interior of the hose. Moreover, the clamping portions can be moved with respect to each other into an opened relative position in which the hose arranged between the clamping portions is not pinched off, so that the medium is able to flow through the interior of the hose. The pump is distinguished in that a sensor is provided thereon, in particular in the seating for the hose clamp, which sensor detects at least when the hose clamp is received in the seating—whether their clamping portions are in the closed or opened relative position.
