Kidney substitution device to standardize and/or automize blood sampling procedure in a kidney substitution treatment machine

摘要

The invention relates to a method and a device to standardize the blood sampling procedure in a kidney substitution treatment, wherein said standardization maximizes the accuracy of blood based Kt/V measurements, while it enhances the usability of the kidney substitution treatment machine by relieving the user of paying attention to the standard blood sampling procedure, wherein the kidney substitution treatment is provided by a machine, which has an extracorporeal blood system pumping the patient blood at a preset blood flow rate through the blood chamber of a dialyzer (3), which is divided by a semi-permeable membrane into the blood chamber (3a) and a dialyzing fluid chamber (3b), and wherein the dialyzing fluid flows at a preset flow rate through the dialyzing fluid system of the machine and collects the waste products from the patient after flowing through the dialyzing fluid chamber of the dialyzer (3), and wherein there is a special key either in the touch screen or the housing of the kidney substitution treatment machine, which triggers a sequence of actions standardizing the blood sampling procedure, and wherein different sequence of actions or protocols standardizing the blood sampling procedure are available and selectable either by the user or by the technician.
