Patent number: 10857291Abstract: 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.Type: GrantFiled: May 29, 2019Date of Patent: December 8, 2020Assignee: B.
