Device for extracorporeal blood treatment involving a change of concentrate

Abstract

A device for extracorporeal blood treatment comprising at least a first concentrate connection which is set up to feed at least a first concentrate into the device for extracorporeal blood treatment as the basis for generating a dialysate; at least a second concentrate connection which is configured to feed at least a second concentrate into the device for extracorporeal blood treatment as the basis for generating a dialysate; wherein the device for extracorporeal blood treatment is configured to switch over from supplying the at least first concentrate to supplying the at least second concentrate at a predetermined time or after a predetermined period of time during an ongoing blood treatment.

1 . Device for extracorporeal blood treatment, comprising:
 at least a first concentrate connection which is configured to feed at least a first concentrate into the device for extracorporeal blood treatment as a basis for generating a dialysate; and   at least a second concentrate connection which is configured to feed at least a second concentrate into the device for extracorporeal blood treatment as a basis for generating a dialysate; wherein   the device for extracorporeal blood treatment is configured to switch over at a predetermined time during an ongoing blood treatment or after a predetermined period of time from feeding the at least first concentrate to feeding the at least second concentrate.   
     
     
         2 . Device for extracorporeal blood treatment according to  claim 1 , wherein the device is configured to carry out the switchover from supplying the at least first concentrate to supplying the at least second concentrate automatically. 
     
     
         3 . Device for extracorporeal blood treatment according to  claim 1 , wherein the first concentrate is an acid concentrate and the first concentrate connection is a first acid concentrate connection, and the second concentrate is an acid concentrate and the second concentrate connection is a second acid concentrate connection. 
     
     
         4 . Device for extracorporeal blood treatment according to  claim 1 , wherein at least one of the first concentrate or the second concentrate is provided in the form of a liquid concentrate supply or a dry concentrate supply in at least one of a first or a second concentrate container, respectively, wherein the first concentrate container is connected to the first concentrate connection in a way which is permeable to concentrate and the second concentrate container is connected to the second concentrate connection in a way which is permeable to concentrate. 
     
     
         5 . Device for extracorporeal blood treatment according to  claim 1 , wherein at least one existing bicarbonate connection is configured as the first or the second concentrate connection in such a way that the first or the second concentrate can be supplied to the device via the existing bicarbonate connection, wherein bicarbonate (BI) can be supplied separately from the existing bicarbonate connection. 
     
     
         6 . Device for extracorporeal blood treatment according to  claim 1 , further comprising:
 at least one further concentrate connection.   
     
     
         7 . Device for extracorporeal blood treatment according to  claim 1 , wherein a large number of types of usable first and second concentrates are stored in advance in a storage facility of the device, and at least the first concentrate and at least the second concentrate are selected at the device from the large number of usable concentrates known to the device. 
     
     
         8 . Device for extracorporeal blood treatment according to  claim 1 , wherein the device is configured to log a concentrate changeover time in the course of an ongoing treatment and to make this logged concentrate changeover time available as a predefined time for at least one subsequent treatment. 
     
     
         9 . Device for extracorporeal blood treatment according to  claim 1 , wherein the device is configured to learn and save at least one correct patient-oriented selection of concentrates, mixture ratios of the same and a connection assignment to selected concentrates over the course of several treatments. 
     
     
         10 . Device for extracorporeal blood treatment according to  claim 1 , wherein when a change in a concentrate-related mixing ratio is registered by the device, the device is configured to request at least one of a verification or confirmation of a correct connection of at least one concentrate container being used.
