MEASUREMENT DEVICE FOR DETERMINING THE FLOW AND PRESENCE OF FLUIDS FOR PARENTERAL NUTRITION, PHARMACEUTICALS OR BIOTECHNOLOGY OR OF BLOOD OR BLOOD COMPONENTS AS THE MEDIUM

摘要

The invention relates to measurement devices for determining the flow and presence of fluids for parenteral nutrition, pharmaceuticals or biotechnology or of blood or blood components as the medium having a measuring tube, two ultrasound converters for and having coupling to the measuring tube and a receptacle part. The measurement devices are particularly distinguished in that the flow and the presence of even the smallest quantities of the medium are easily and reliably measurable. To this end, the measuring tube is a tube closed on both ends with a tube bottom and having shell flanges arranged on the end regions as a connection. The receptacle part consists of housing parts, between which the measuring tube can be placed. The housing parts each have an ultrasound converter, wherein at least one of the ultrasound converters is movable by means of a piston. The receptacle part has at least one sensor for detecting the temperature of at least one region of the measuring tube and, consequently, of the medium in the measuring tube. Furthermore, the ultrasound converters and the sensor are connected to at least one data processing system.
