Problems solved by technology

[0008] Such contamination can have an effect on subsequent treatment of another patient with the same blood therapy equipment
If extremely thorough cleaning procedures are not carried out in addition to the customary cleaning procedures, the dialysis fluid inlet line and thus the dialysis fluid compartment of the dialysis filter may be contaminated with pathogens from the blood of the patient being treated at the time of the rupture and contamination by other substances

Embodiment Construction

[0063] figure 1 A cross-sectional view of the blood treatment device 1000 according to the first embodiment of the present invention is schematically shown in a very simplified manner.

[0064] The blood treatment device 1000 includes a dialysate introduction line 1 with a first connector 3 and a second dialysate withdrawal line 5 with a second connector 7. If necessary, both the first connector 3 and the second connector 7 can be designed as Hansen couplers or other types of connectors.

[0065] The blood treatment device 1000 further includes a multi-part adaptor 9 as needed, so as to detachably hold the diafiltration filter 100 having a blood side and a dialysate side. The dialysate withdrawal line 5 includes a blood leakage sensor 11 to detect blood in the inside of the dialysate withdrawal line 5. However, as another alternative or in addition, the blood leakage sensor 11 may be provided at any other position that can detect the transfer of blood from the blood side of the di...

Abstract

The invention relates to a blood treatment device (1000), comprising a dialysis filter (100) or a receptacle (9) for a dialysis filter (100), a dialysis-fluid supply line (1) having a first connector (3) for supplying dialysis fluid to the dialysis filter (100), a dialysate discharge line (5) having a second connector (7) for discharging dialysate from the dialysis filter (100), a blood leakage sensor (11) configured and arranged to detect blood in or on the dialysis filter (100), in the dialysis-fluid supply line (1), and / or in the dialysate discharge line (5) and configured to output a blood leakage signal (BLS) if blood is detected, a short-circuit line (13) for connecting the dialysis-fluid supply line (1) and, or to, the dialysate discharge line (5) in fluid communication, wherein for this purpose the short-circuit line (13) has a third connector (15) and a fourth connector (17) each for connecting to one of the first and second connector (3, 7), and a controller (33).

Description

Technical field [0001] The invention relates to a blood treatment device as described in the preamble of claim 1. The invention further relates to a method according to the preamble of claim 10 and a method according to the preamble of claim 12 for replacing a diafilter or hemofilter of a blood treatment device. Background technique [0002] From practice, blood treatment devices with hemofilters or diafiltration filters are known. Both the blood and the dialysate are led through the dialysis filter to the compartments separated by the dialysis membrane (ie, the blood compartment and the dialysate compartment). The diafiltration filter is connected to the patient through the extracorporeal blood circuit and connected to the blood treatment equipment through the dialysis fluid feed line and the dialysis fluid discharge line. Each of these two lines includes a diafiltration filter for the dialysate discharge line. The connector to make the connection. These two connecting sides ...
