Abstract
In an extracorporeal blood treatment apparatus, a user interface (22) has a touch screen for displaying two bar-graphs (24) of pressures in the extracorporeal blood circuit. By touching a bar-graph three alpha-numeric values appear: a reference value (29), an upper safety interval (28) of the pressure, comprised between an upper limit value and the reference valve (29), and a lower interval value (30), comprised between the reference value and a lower limit value. The reference value is a measured pressure value. Four buttons also appear on the display for input of modifications to the upper interval and the lower interval. The setting of the total pressure safety interval is simple and immediate.

16. An extracorporeal blood treatment apparatus, comprising:
-
a blood treatment device having a blood chamber and a fluid chamber which are separated from one another by a semipermeable membrane; an extracorporeal blood circuit having a removal line for sending blood from a patient to the blood chamber, and a return line for returning the blood from the blood chamber to the patient; a fluid circuit connected to the fluid chamber; one or more sensors for measuring a value of a parameter in the extracorporeal blood circuit and in the fluid circuit; a user interface provided with a screen and connected to the one or more sensors; selecting means for enabling a user to modify at least a safety value via the screen, the at least a safety value being equal to an amount of an interval, the interval being comprised between a limit value for the parameter and a reference value for the parameter, the reference value being a measured value of the parameter. - View Dependent Claims (17, 18, 19)

32. An extracorporeal blood treatment apparatus comprising:
-
a blood treatment device having a blood chamber and a fluid chamber separated from one another by a semipermeable membrane; an extracorporeal blood circuit having a removal line for sending blood from a patient to the blood chamber, and a return line for returning the blood from the blood chamber to the patient; a fluid circuit connected to the fluid chamber; one or more sensors for measuring a value of a parameter in the extracorporeal blood circuit and in the fluid circuit, the parameter comprising a parameter selected from a following group of parameters;
an arterial pressure in the removal line, a venous pressure in the return line, a trans-membrane pressure between the blood chamber and the fluid chamber;a user interface provided with a screen and connected to the one or more sensors; selecting means for enabling a user to modify, via a screen, a first safety value and a second safety value, the selecting means comprising a video display on the screen including an alpha-numeric representation of both the at least a safety value and the reference value, the first safety value and the second safety value being equal to a size respectively of an upper interval and a lower interval, the upper interval being comprised between an upper limit value for the parameter and a reference value of the parameter, the lower interval being comprised between the reference value and a lower limit value of the parameter, the reference value being a measured value of the parameter. - View Dependent Claims (33)
