Abstract

An extracorporeal blood purification system with at least one extracorporeal blood purification apparatus, preferably dialysis machine, which is prepared to go through a centrally controlled disinfection process for a blood purification process, as well as with an internal fluid line system which is disinfected at least during the disinfection process by a disinfectant, including an internal or external disinfecting or cleaning case which is at least during the disinfection process via at least one case connection connected to the internal fluid conduit system to receive disinfectant.

First claim

The invention claimed is:

1. An extracorporeal blood purification system comprising:
an extracorporeal blood purification machine configured for a centrally controlled disinfection process following a blood purification process;
an internal fluid line system within the extracorporeal blood purification machine through which a disinfectant may flow at least during the disinfection process, wherein the internal fluid line system has a fresh dialysis fluid line and a used dialysis fluid line, the fresh dialysis fluid line and the used dialysis fluid line configured to connect to a dialyzer of the extracorporeal blood purification machine;
a flushing bridge integral to the internal fluid line system placed within the extracorporeal blood purification machine, the flushing bridge arranged as a single separate line connected between the fresh dialysis fluid line and the used dialysis fluid line, the flushing bridge configured to short-circuit the dialyzer of the extracorporeal blood purification machine
a plurality of flushing bridge ports arranged on the flushing bridge between the fresh dialysis fluid line and the used dialysis fluid line; and
a disinfection case having a case supply line connected to one of the plurality of flushing bridge ports and a case drain line connected to another of the plurality of flushing bridge ports, the disinfection case configured to receive accessories, wherein, at least during the disinfection process, the one of the plurality of flushing bridge ports supplies fluid to the disinfection case via the case supply line, and the another of the plurality of flushing bridge ports drains the fluid from the disinfection case via the case drain line.

2. The extracorporeal blood treatment system according to claim 1 , wherein the disinfection case is external to the extracorporeal blood purification machine.

3. The extracorporeal blood purification system according to claim 1 , wherein fluid guiding means are provided on at least one of the blood treatment machine or the disinfection case for circulating fluid flow in a fluid guiding system either in a closed internal manner within the blood purification machine and for guiding the fluid flow through the disinfection case during the disinfection process.

4. The extracorporeal blood treatment system according to claim 3 , wherein the fluid guiding means constitute a respective switch point, a valve or a multiple-way cock.

5. The extracorporeal blood treatment system according to claim 3 , wherein the fluid guiding means are adapted to be controlled manually or automatically for changing over the fluid flow between a closed internal fluid circulation within the blood purification machine and the fluid flow through the disinfection case during the disinfection process.

6. The extracorporeal blood purification system according claim 2 , wherein the case supply line and the case drain line of the disinfection case form a circuit having a separate disinfectant supply being communicated with the internal fluid line system.

7. The extracorporeal blood purification system according to claim 1 , wherein the disinfection case includes mechanical connecting elements so that an exterior of the disinfection case can be rigidly coupled to the blood purification machine.

8. The extracorporeal blood purification system according to claim 1 , wherein the disinfection case is formed integrally with the blood purification machine.

9. The extracorporeal blood purification system according to claim 1 , wherein the disinfection case includes a lid sensor provided for detecting whether a case lid is in fluid-tight contact with a case body and hence the case lid is in a closed state or the case lid is not in fluid-tight contact with the case body and hence the case lid is in an open state.

10. The extracorporeal blood purification system according to claim 1 , wherein the disinfection case includes a filling level sensor provided for detecting the volume occupied by the disinfectant inside the case.
