Embodiment Construction

[0043] The method of the invention is implemented in an extracorporeal blood treatment apparatus in the example presented here. The extracorporeal blood treatment device can be, for example, a known hemodialysis device as described in German patent document DE 10 2009 060 668 A1.

[0044] References are made by way of example to describe the hemodialysis apparatus presented here as a typical blood treatment apparatus for use in the present invention. The extracorporeal blood treatment device according to the invention has in particular a control processing unit and a machine-side drive for the impeller blood pump. The impeller blood pump comprises a housing with an impeller and is preferably part of an extracorporeal blood hose set. The extracorporeal blood hose set is particularly advantageously designed as a disposable blood collection cassette, the extracorporeal blood hose assembly being configured to be coupled to an extracorporeal blood treatment device.

Abstract

The invention relates to a method for monitoring an extracorporeal blood treatment device with an extracorporeal blood circuit, in particular a method for monitoring disconnection of a venous needle at the extracorporeal blood circuit by means of a pressure pulse measurement method. The invention also relates to a device for carrying out a monitoring method and a blood treatment device comprising a corresponding monitoring device.

Description

technical field [0001] The invention relates to a monitoring method of an extracorporeal blood treatment device according to the preamble of claim 1 , as well as a device implementing the method and a corresponding blood treatment device. Background technique [0002] The invention specifically addresses the problem of recognition of a disconnected venous needle by means of a pressure pulse measurement method at the extracorporeal blood circuit. [0003] An unrecognized disconnection of the venous needle may result in a horribly free flow of blood from the venous needle to the environment, if the pumping cycle of the corresponding blood pump is not interrupted. If such a serious error is not recognized immediately, the patient will bleed to death within minutes with a typical blood flow of 200ml / min to 300ml / min. However, the disconnection of the arterial needle is detected immediately and reliably by the air bubble detector, which is always present in the blood treatment d...
