Abstract

The invention relates to a medical treatment apparatus comprising a tube set, a peristaltic pumpfor conveying fluid, and a monitoring apparatusfor monitoring the occlusion of the positive displacement elementsA,B of the peristaltic pump. In addition, the invention relates to a tube setfor a medical treatment apparatus, and to a method for monitoring the occlusion of the occlusion elements of a peristaltic pump for conveying a fluid for a medical treatment apparatus. The invention is based on the fact that the occlusion of the positive displacement elementsA,B of the peristaltic pumpis monitored in order to monitor the fluid flow in the hose line. For this purpose, the electrical resistance or a variable which correlates with the electrical resistance is measured between a first and a second electrodeA,B, the first electrodeA being arranged on the hose lineupstream of the occlusion elementsof the peristaltic pumpand the second electrodebeing arranged on the hose line downstream of the occlusion elements such that an electrical contact is produced between the first and second electrodeA,B and the fluid flowing in the hose line. The electrodesA,B are preferably integral component parts of a connecting piece, by means of which the hose segmentA to be inserted into the peristaltic pumpis fixed in the form of a loop.
