Patent ID: 8556819

Claim:
A therapy device for extracorporeal blood treatment, comprising: a blood-pressure measuring device and a memory-supported controller that controls blood pressure of a patient using settable treatment parameters, wherein said memory-supported controller is configured to perform the following functions during a current therapy procedure: a) detecting and storing a temporal development of the blood pressure during the current therapy procedure; b) analytically comparing the temporal development of the blood pressure up to a current point of time during the current therapy procedure with temporal developments of the blood pressure of preceding therapy procedures up to a respective point of time corresponding to the current point of time of the current therapy procedure; c) selecting the temporal developments of the blood pressure of the preceding therapy procedures that are most similar up to the respective point of time to the temporal development of the blood pressure of the current therapy procedure up to the current point of time of the current therapy procedure; d) analyzing the selected temporal developments of the blood pressure of the preceding therapy procedures to detect in the selected temporal developments of the blood pressure of the preceding therapy procedures a decrease in the blood pressure beyond the respective point of time; e) choosing at least one of the selected temporal developments of the blood pressure of the preceding therapy procedures having the decrease in the blood pressure beyond the respective point of time; and f) preventing a decrease in the blood pressure of the current therapy procedure, wherein the temporal development of the at least one the selected temporal developments of the blood pressure of the preceding therapy procedures beyond the respective point of time used as a guide value to prospectively control the blood-pressure in time periods beyond the current point of time of the current therapy procedure.
