Blood treating device

摘要

A blood treatment unit has a blood treatment device which is part of an extracorporeal blood circulatory system. The unit has a control unit and a display and input unit having a touch screen. In order to simplify the operation of the blood treatment unit using the touch screen, the control unit and the display and input unit are suitable for representing various mode means on the touch screen which correspond to the various time modes of the blood treatment. The control unit automatically instigates the beginning of the following time mode at the end of at least one time mode, this being indicated by a change in the representation of the selected mode means on the touch screen. It is especially advantageous to use sensors through whose measured values the control unit identifies the end of one time mode and the beginning of the subsequent time mode.

1. A blood treatment unit comprising
a blood treatment device that is part of an extracorporeal blood circulatory system, said system including a blood line, a blood pump, and a contact sensor associated with the blood pump, actuators in at least one of the extracorporeal blood circulatory system and another fluid circulatory system, a control unit for controlling the actuators, and a display and input unit including a touch screen connected to the control unit, the display and input unit including on the touch screen a plurality of mode means selectable to influence operation of a blood treatment, the mode means being configured to display various time modes of the blood treatment to be selectable by an operator via the touch screen, and to be sequentially arranged with respect to one another in order of their occurrence in time during the blood treatment, and including a blood treatment preparation means that includes a blood system mode and a preparation mode, one blood treatment means, and one blood treatment after-preparation means, and the control unit being programmed (i) to identify the respectively running time mode and to instruct the display and input unit to show the corresponding mode means selected from other mode means, by showing the other mode means in a first type of symbol and the selected mode means in a second type of symbol, (ii) to establish an end of at least one of the time modes, (iii) to automatically initiate a beginning of a subsequent time mode, and (iv) to communicate the initiation of the time mode to the display and input unit for changing the representation of the selected mode means, with the blood treatment unit being configured such that at the beginning of the blood treatment, the blood treatment device initiates the blood system mode, and (a) if a proper insertion of the blood hose is not detected by the contact sensor, the blood system mode remains active, with the blood system mode being displayed on the control unit, and (b) once a proper insertion of the blood hose is detected by the contact sensor, the control unit initiates the end of the blood system mode and the initiation of the reparation mode, with the preparation mode being displayed on the control unit.
