Abstract

The device is for fitting on the upstream side of a transfusion pump, and compresses the tube system to a greater or lesser degree so as to allow the fluid to drip into the inside of it, at a frequency previously determined. Compression can be by the moving part of an electromagnet, working in a groove. Inside the coil is a plunger which is screw adjustable, and a scale arrangement enables external controlled fluid regulation.
