Abstract
The invention relates to a medical treatment apparatus comprising a tube set 20, a peristaltic pump 6 for conveying fluid, and a monitoring apparatus 15 for monitoring the occlusion of the positive displacement elements 13A, 13B of the peristaltic pump. In addition, the invention relates to a tube set 20 for 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 elements 13A, 13B of the peristaltic pump 6 is monitored in order to monitor the fluid flow in the hose line 5. For this purpose, the electrical resistance or a variable which correlates with the electrical resistance is measured between a first and a second electrode 16A, 16B, the first electrode 16A being arranged on the hose line 5 upstream of the occlusion elements 12 of the peristaltic pump 6 and the second electrode 16b being arranged on the hose line downstream of the occlusion elements such that an electrical contact is produced between the first and second electrode 16A, 16B and the fluid flowing in the hose l…
