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 . The arterial blood line provided with the blood pump leads from the patient to the inlet of the blood chamber 3 , while the 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 is a peristaltic tube pump, in particular a roller pump, wherein the arterial and venous blood lines are flexible tube lines specially designed for ...

Abstract

The invention relates to a medical treatment device with a hose set 20 and a peristaltic hose pump 6 for conveying liquids, and a monitoring device for monitoring the obstruction of the obstruction bodies 13A, 13B of the hose pump. 15. The invention also relates to a hose set 20 for a medical treatment device and a method for monitoring a blockage of an obstruction body of a peristaltic hose pump for conveying a medical treatment device of liquid. The invention is based on the monitoring of a blockage of the blocking bodies 13A, 13B of the peristaltic hose pump 6 in order to monitor the fluid flow in the hose line 5 . For this, the resistance or a variable associated with said resistance is measured between the first electrode 16A, which is arranged on the hose line 5 upstream of the blocking body 12 of the peristaltic pump 6 and which is connected to the resistance. The second electrode 16B is arranged on the hose line 5 downstream of the blocking body, so that electrical contact is established between the first and second electrodes 16A, 16B and the liquid flowing in said hose line 5 . The electrodes 16A, 16B are preferably integral components of the connecting piece 10 , by means of which the hose section 5A in the form of a loop to be inserted into the hose pump 6 is fixed.

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...
