Abstract

A rinsing line for discharging a rinsing fluid out of a medical technical functional device having been rinsed by means of the rinsing fluid is described, in which the rinsing line is, on the one side, connected, provided or intended for being connected with a section of the medical technical functional device and in which the rinsing line is, on the other side, connected with, provided or intended for being connected with a fluid supplying device for supplying a medical fluid into the medical technical functional device. A medical technical functional device, a medical technical treatment apparatus, a method and a control unit are also described.

First claim

The invention claimed is:

1. A medical technical functional device comprising:
a rinsing line configured to discharge a rinsing fluid out of the medical technical functional device which was rinsed or flushed with the rinsing fluid;
an extracorporeal blood circuit comprising an arterial line section, wherein a blood pump is arranged along the arterial line section;
a predilution access, wherein a portion of the arterial line section extends from the blood pump to the predilution access; and
a rinsing valve directly connected to the rinsing line and directly connected to the portion of the arterial line section that extends from the blood pump to the predilution access,
wherein the rinsing line is connected with or configured to be connected with a fluid supplying device configured to supply a medical fluid into the medical technical functional device.

2. The medical technical functional device according to claim 1 , further comprising:
a port, the port comprising at least:
an inner tubing segment having a first lumen; and
an outer tubing segment having a second lumen, wherein the outer tubing segment is arranged at least around one area of the inner tubing segment such that a space is formed within the second lumen between an exterior of the inner tubing segment and the outer tubing segment;
wherein the first lumen of the inner tubing segment is configured to at least one of receive or conduct the medical fluid, and wherein the space of the outer tubing segment is configured to at least one of receive or conduct at least the rinsing fluid, or vice versa.

3. The medical technical functional device according to claim 1 , wherein the medical technical functional device is configured as one of an extracorporeal blood tubing set, a blood treatment cassette, or a disposable blood treatment cassette.

4. A medical technical treatment apparatus, connected with or configured to be connected with at least one medical technical functional device according to claim 1 .

5. A method comprising at least one of rinsing, flushing or priming the medical technical functional device according to claim 1 .

6. The method according to claim 5 , further comprising:
at least partially discharging or draining, respectively, the rinsing fluid out of the rinsed medical technical functional device through the rinsing line into a port or a machine connector for supplying substituate liquid from a medical technical treatment apparatus into the medical technical functional device.

7. A control unit, configured to be used with the medical technical treatment apparatus according to claim 4 , and configured for automatically performing or executing the method of at least one of rinsing, flushing or priming the at least one medical technical functional device.

8. The medical technical functional device according to claim 1 , wherein the medical technical functional device further comprises the fluid supplying device, wherein the fluid supplying device is a port for supplying a substituate liquid into the medical technical functional device.

9. The medical technical functional device according to claim 1 , wherein the medical technical functional device further comprises the fluid supplying device, wherein the fluid supplying device is or comprises a biluminal connection section configured to concurrently conduct two fluids.

10. The medical technical functional device according to claim 1 , wherein the medical technical functional device further comprises a blood cassette.

11. The medical technical functional device according to claim 10 , wherein the arterial line section of the extracorporeal blood circuit is arranged between (a) the blood pump or an intervention or engaging section of the extracorporeal blood circuit for the blood pump and (b) an extracorporeal blood treatment device.
