Problems solved by technology

[0009] In peristaltic hose pump operation, a clogged hose line cannot be reliably detected solely by monitoring the pressure in the hose line, since the pressure does not rise further beyond a certain limit value when the displacement body is lifted

Embodiment Construction

[0036] In the present exemplary embodiment, the medical therapy device is an extracorporeal blood therapy device, in particular a hemodialysis device, which has a dialyzer 1 divided by a semipermeable membrane 2 into a blood chamber 3 and a dialysate chamber 4 . An arterial blood line 5 provided with a blood pump 6 leads from the patient to the inlet of the blood chamber 3 , while a venous blood line 7 leads from the outlet of the blood chamber to the patient.

[0037] Fresh dialysate is provided in dialysate source 8 . A dialysate supply line 9 leads from the dialysate source 8 to the inlet of the dialysate chamber 4 of the dialyzer 1 , while a dialysate outlet line 30 leads from the outlet of the dialysate chamber 4 to the drain 11 . The dialysate pump 12 is arranged in the dialysate discharge line 30 .

[0038] The blood pump 6 is a peristaltic hose pump, in particular a roller pump, wherein the arterial and venous blood lines 5, 7 are flexible hoses specially designed for...

Abstract

The invention relates to a medical treatment device having a hose set (20) and a peristaltic hose pump (6) for conveying fluid, and having a monitoring device (15) for monitoring the occlusion of thedisplacer (13A, 13B) of the hose pump. The invention further relates to a hose set (20) for a medical treatment device and to a method for monitoring the occlusion of the occlusion element of a peristaltic hose pump for conveying a fluid for a medical treatment device. The invention is based on the occlusion of the displacer (13A, 13B) of the peristaltic hose pump (6) being monitored in order to monitor the fluid flow in the hose line (5). In order to do so, the electrical resistance or a parameter correlating with the electrical resistance is measured between a first and a second electrode (16A, 16B), wherein the first electrode (16A) is arranged on the hose line (5), upstream of the occlusion element (12) of the peristaltic pump (6), and the second electrode (16b) is arranged on the hoseline (5), downstream of the occlusion element, such that an electrical contact between the first and second electrode (16A, 16B) and the fluid flowing in the hose line (5) is produced. The electrodes(16A, 16B) are preferably an integral component of a connector (10), by means of which the hose segment (5A) to be inserted into the hose pump (6) is fixed in the form of a loop.

Description

technical field [0001] The invention relates to a medical treatment device, in particular an extracorporeal blood treatment device, with a hose set and a peristaltic hose pump for conveying liquids and for monitoring a blockage of a squeeze body of the peristaltic hose pump Monitoring equipment. Furthermore, the invention relates to a hose set for a medical treatment device, in particular an extracorporeal blood treatment device, and a method for monitoring a blockage of an obstruction body of a peristaltic hose pump with For the delivery of liquids used in medical therapeutic devices. Background technique [0002] In extracorporeal blood therapy, the blood to be treated flows in an extracorporeal blood circuit through the blood compartment of a dialyzer, which is divided by a semipermeable membrane into a blood compartment and a dialysate compartment, while in a dialysate system the dialysate flows through the dialyser Dialysate compartment of the machine. The extracorpo...
