Abstract

The invention relates to a method and apparatus for optimizing an extracorporeal blood treatment using an extracorporeal blood treatment apparatus, an extracorporeal blood treatment apparatus with a device for optimizing the extracorporeal blood treatment, and a computer program to be executed on a processor for carrying out a method for optimizing the extracorporeal blood treatment. The method and apparatus are characterized in that at least one machine-specific treatment parameter for carrying out the treatment using the respective dialyzer or filter is determined with a computing unit for different types of dialyzers or filters. The computing unit determines the costs resulting from the determined machine-specific treatment parameters when using the respective dialyzer or filter. The determined costs for different types of dialyzers or filters are then displayed on a display unit. The doctor can then select the dialyzer or filter to keep the costs as low as possible.

a computing unit configured to determine a machine-specific treatment parameter from the one or more patient-specific treatment parameters for performing the treatment using each dialyzer or filter from a group of different types of dialyzers or filters having different dialyzing fluid flows and further determine a cost of the extracorporeal blood treatment resulting from the machine-specific treatment parameter using each dialyzer or filter; and

a display unit configured to display a cost resulting from the machine-specific treatment parameter using each dialyzer or filter from the group of different types of dialyzers or filters, the display unit comprising at least four display screen areas comprising;

a first screen area configured to display at least one therapeutic aim parameter,

a second screen area configured to display at least one patient parameter,

a third screen area configured to display at least one apparatus parameter, and

a fourth screen area configured to display a dialyzer or filter that would result in a lowest cost treatment;

inputting one or more patient-specific treatment parameters using the input unit, wherein said patient-specific treatment parameters are characteristic of the therapeutic aim, the patient to be treated, or both;

displaying the one or more inputted patient-specific treatment parameters in the second screen area;

displaying the group of different types of dialyzers or filters in the third screen area;

determining a respective machine-specific treatment parameter, from the one or more patient-specific treatment parameters, for performing the extracorporeal blood treatment, for each dialyzer or filter from the group of different types of dialyzers or filters displayed in the third screen area, using the computing unit;

calculating a quantity of the respective consumables or a quantity of energy that would be consumed in the performance of the extracorporeal blood treatment with the ascertained machine-specific treatment parameter, using the computing unit;

determining the cost of carrying out the extracorporeal blood treatment resulting from the ascertained machine-specific treatment parameter, based on the quantity of the respective consumables or the quantity of energy that would be consumed, for using each dialyzer or filter, using the computing unit;

displaying in the fourth screen area the respective cost that would result from carrying out the machine-specific treatment parameter using each dialyzer or filter displayed in the third screen area;

selecting the dialyzer or filter with the lowest cost resulting for carrying out the extracorporeal blood treatment; and

performing the extracorporeal blood treatment with the selected dialyzer or filter in the extracorporeal blood treatment apparatus.

2. The method according to claim 1, wherein the step of determining the cost of the extracorporeal blood treatment comprises the following steps:

storing the costs of each of the different types of dialyzers or filters in a memory unit, storing the costs of consumables or the energy costs in the memory unit; and

calculating the costs of the consumables or the cost of the energy consumed during the extracorporeal blood treatment, from the costs of the consumables or the energy costs, and from the calculated quantity of consumables or the calculated quantity of energy,

wherein the total cost for each dialyzer or filter is calculated with the computing unit from the sum of the stored costs of the respective dialyzer or filter and the calculated costs of the consumables or the energy consumed to carry out the extracorporeal blood treatment.

3. The method according to claim 1, further comprising displaying the different quantities of the machine-specific treatment parameter for the different dialyzers or filters, the total cost of the extracorporeal blood treatment resulting from the use of the given dialyzer or filter, and an adjustment of the given machine-specific treatment parameter, on the display unit.

4. The method according to claim 1, wherein the machine-specific treatment parameter comprises dialyzing fluid flow with which dialyzing fluid flows through the second chamber of the dialyzer or filter.

5. The method according to claim 1, wherein the one or more patient-specific treatment parameters are selected from the group consisting of:

blood distribution volume V, duration T of the extracorporeal blood treatment, the dialysis dose, clearance K, and blood flow Q_b in the extracorporeal blood circuit.

6. The method according to claim 1, further comprising:
